What's included in our GST/HST filing services

GST/HST looks simple: charge it, collect it, send it in. In practice most of the problems we see come from small things done wrong for months: a registration that started late, Ontario HST charged to a customer in Alberta, ITCs claimed on receipts with no supplier number, or a return filed from bank deposits instead of reconciled books. Our GST/HST filing services deal with all of it.

  • Registration. We work out whether and when you need to register, register you with the CRA, and pick the effective date and filing frequency that suit you.
  • Return preparation. We work out the GST/HST you collected and the input tax credits (ITCs) on your expenses, and reconcile both to your books.
  • Filing and payment reminders. We file through GST/HST NETFILE or Represent a Client, and tell you what to pay and when.
  • Quick method review. If your business qualifies, we check whether the quick method would leave you with less to remit.
  • Clean-up of missed returns. Unfiled or late returns are quoted as a fixed-fee catch-up. When the books are behind too, our catch-up bookkeeping starts from $1,800 per year.
  • Voluntary disclosures. Where it helps, we prepare a Voluntary Disclosures Program (VDP) application so penalties and part of the interest can be relieved. Quoted after a call.
  • CRA reviews. If the CRA asks for support for your ITCs, we pull the receipts and respond with you.
  • Account changes and closing. We change your filing frequency, add or close program accounts, and file the final return when you stop.
  • Provincial sales tax for clients. We file Manitoba RST returns for clients through TAXcess. (see below)

What's on a GST/HST return, line by line

A GST/HST return is a short form, but every line has to tie to your books:

← Swipe to compare →

LineWhat it reportsWhat we check
101Sales and other revenue for the periodAgrees to the revenue in your books and, over the year, to the revenue on your T2 or T2125
103GST/HST collected or collectibleMatches the GST/HST payable account in your books
105Total GST/HST and adjustments (line 103 plus line 104 adjustments)Includes any adjustments, such as tax on bad debts recovered
108Total ITCs and adjustments (line 106 ITCs plus line 107 deductions, such as GST/HST in bad debts or the quick method 1% credit)Supported by receipts that meet the documentation rules
109Net tax (line 105 minus line 108)The amount owing or refundable
205 / 405205: GST/HST due on purchases of taxable real property (or emission allowances) where you self-assess. 405: other GST/HST to be self-assessed, such as imported services or the provincial part of HSTIncluded where you bought taxable property or imported services

The CRA compares the sales you report for GST/HST with the revenue on your income tax return, so a gap between the two is a common reason for a review. We reconcile both every year.

Law: Excise Tax Act s.225(1) (net tax); Excise Tax Act s.238(1) (filing returns).

Do you need to register for GST/HST?

Most businesses must register once their worldwide taxable supplies, together with associated businesses, go over $30,000 in a single calendar quarter or over four consecutive calendar quarters. Below that you’re a small supplier and registering is optional, though registering voluntarily lets you claim ITCs. Taxi, rideshare and some other businesses must register from their first dollar. Source: CRA: when to register for and start charging GST/HST. Our guide when does a Canadian business have to register for a GST/HST number? goes into more detail.

Law: Excise Tax Act s.240(1) (registration required); Excise Tax Act s.148(1) (small suppliers).

How the $30,000 small supplier test works

The test is about taxable supplies (sales), not profit, and it counts zero-rated sales such as exports too. It doesn’t count exempt supplies such as residential rent, most financial services, or the sale of capital property. Associated businesses are added together, so two corporations with the same owner can each be under $30,000 and still have to register.

← Swipe to compare →

SituationWhen you must start charging GST/HSTWhen you must register
Over $30,000 in a single calendar quarterOn the sale that takes you over $30,000Within 29 days of that sale
Over $30,000 over four consecutive quarters, but not in one quarterFrom the first day of the second month after the quarter you went overBy the day you must start charging
Taxi, limousine or commercial ride-sharing driverFrom your first fareBefore your first fare
Non-resident performer or event seller in CanadaFrom your first saleBefore your first sale
Public service body (charity, non-profit, municipality)Threshold is $50,000, not $30,000Within 29 days of going over

Evergreen note: the $30,000 threshold has not changed since 1991, but always check the CRA page linked above before relying on it.

Should you register voluntarily?

Registering before you have to can be worth it. As a registrant you claim back the GST/HST you pay on equipment, software, rent, a vehicle and professional fees, which can be meaningful in the first year when expenses are high and sales are low. You also look established to larger customers, many of whom expect a GST/HST number on every invoice.

The trade-off is that you must charge GST/HST on every taxable sale and file every return, including nil returns. If your customers are mainly consumers who can’t claim ITCs, charging 13% may make you more expensive than an unregistered competitor.

← Swipe to compare →

Voluntary registrationUsually worth itUsually not worth it
CustomersMostly GST/HST-registered businessesMostly consumers who can't claim the tax back
Start-up costsHigh (equipment, fit-out, software)Low
Growth plansExpect to pass $30,000 soonSide income likely to stay small
AdminBooks already kept monthlyNo bookkeeping in place

Once registered voluntarily, you generally have to stay registered for at least one year before you can cancel.

Getting the registration details right

  • Effective date. It sets the first day you must charge tax and the first day you can claim ITCs. When you register voluntarily you can usually ask for an effective date up to 30 days before the day you apply. A corporation's effective date can't be before its incorporation date. Going back more than 30 days needs a written request to the CRA.
  • Program accounts. GST/HST is the RT account on your business number. At the same time we check whether you also need payroll (RP), corporate income tax (RC) or import-export (RM) accounts.
  • Fiscal year and reporting period. Your GST/HST fiscal year normally follows your income tax year-end, and the reporting period you elect sets your filing rhythm.
  • Elections from day one. If the quick method or the simplified ITC method suits you, we set it up from your first period.
  • Invoices and software. Once registered, your invoices must show your GST/HST number on sales to registrants, and we set the right tax codes in QuickBooks Online or Xero so each sale is taxed correctly.

Non-resident businesses

A non-resident that carries on business in Canada registers under the normal rules and, if it has no permanent establishment here, usually has to post security with the CRA. A non-resident selling digital products or services to Canadian consumers, with no business in Canada, uses the simplified registration instead (see below). We tell you which applies.

GST/HST rates by province

In Ontario, HST is 13%. Other provinces charge GST alone or a different HST rate, and what you charge depends on where your customer is (CRA: GST/HST rates).

← Swipe to compare →

Province or territoryTax you charge (GST/HST)Separate provincial sales tax
OntarioHST 13%None
New BrunswickHST 15%None
Newfoundland and LabradorHST 15%None

ManitobaGST 5%RST 7% (administered by MB)
QuebecGST 5%QST 9.975% (administered by Revenu Québec)
AlbertaGST 5%None
Yukon, Northwest Territories, NunavutGST 5%None

Evergreen note: rates as of October 2026. Provinces change their rates from time to time (Nova Scotia last did on April 1, 2025), so the CRA rates page linked above is the one to check before you invoice.

Law: Excise Tax Act s.165(1) (GST imposed); Excise Tax Act s.165(2) (tax in participating provinces).

Which rate to charge: place of supply in plain English

The rate follows the customer, not you. An Ontario business shipping goods to a customer in Calgary charges 5% GST, not 13% HST. For services the rule usually looks at the customer’s business or home address you get in the normal course of business. For real property, it’s where the property is. Exports of goods and many services to non-residents are zero-rated: you charge 0% but still claim your ITCs.

← Swipe to compare →

You are in Ontario and you sell…Customer inUsually charge
Goods delivered to the customerNova Scotia14% HST
Goods delivered to the customerAlberta5% GST
Consulting servicesBritish Columbia (BC address)5% GST (the BC client handles BC PST separately)
Consulting servicesUnited States (non-resident, not registered)0% (zero-rated), in most cases
Repairs to a buildingBuilding in New Brunswick15% HST

Exempt vs zero-rated, with examples. Exempt supplies include most health care services, child care, residential rent, music lessons and most financial services; you charge no tax and can’t claim ITCs on the costs of making them. Zero-rated supplies include basic groceries, prescription drugs and most exports; you charge 0% and claim your ITCs. Getting the category wrong either overcharges customers or leaves you paying the tax yourself.

Imports. Goods you import are charged GST by the CBSA at the border, and as a registrant you can usually claim it back as an ITC. If you import commercial goods into an HST province, you generally self-assess the provincial part of the HST on line 405 of your return (and can usually claim it back as an ITC in the same return). Keep the customs accounting documents (B3 or CARM statements) as support.

Charging Ontario HST to every customer is one of the most common errors we fix. If the customer is a registrant they may just claim it back, but a consumer overcharged by 8 points won’t be happy, and undercharging leaves you paying the difference.

Saskatchewan PST and Manitoba RST

British Columbia, Saskatchewan, Manitoba and Quebec run their own sales taxes alongside GST, with separate registration and returns. We do file Manitoba RST returns for clients through Manitoba’s TAXcess portal. If you sell into BC, Saskatchewan, Manitoba or Quebec, we’ll tell you whether you need a provincial registration as well as your GST/HST number.

How often you file

Annual taxable supplies (you and associates)Default filing frequencyOptional
$1.5 million or lessAnnualQuarterly or monthly
More than $1.5 million up to $6 millionQuarterlyMonthly
More than $6 millionMonthly–

Source: CRA: reporting periods. See also our post on GST/HST remittance frequencies.

Annual is the least work, but it means one large bill a year. Many small businesses choose quarterly so the tax they’ve collected never sits in the bank long enough to get spent. If you usually get refunds (exporters, start-ups, heavy equipment buyers), monthly gets your money back faster.

Law: Excise Tax Act s.245(2) (reporting period of registrant); Excise Tax Act s.246(1) (monthly election); Excise Tax Act s.247(1) (quarterly election); Excise Tax Act s.248(1) (annual election).

Filing and payment deadlines

← Swipe to compare →

Filing periodReturn and payment due
Monthly or quarterlyOne month after the end of the reporting period
Annual (most businesses)Three months after your fiscal year-end
Annual, individual with business income and a Dec 31 year-endReturn due June 15; payment due April 30

Annual filers may also have to pay quarterly instalments, generally when net tax for the year (or the previous year) is $3,000 or more. Instalments are due one month after the end of each quarter of your fiscal year. Most registrants must file electronically, and all must file a return for every period, even when nothing happened (a nil return).

If you can’t pay, file anyway. The late-filing penalty is based on filing, so filing on time and paying later avoids it, but interest still runs on the unpaid balance from the day after the due date. If you need to change your reporting period (for example to monthly to get refunds faster), you file an election (Form GST20 or online), which generally takes effect on the first day of a fiscal year. Each return we file through NETFILE or Represent a Client gets a CRA confirmation number, which we keep on your file.

Evergreen note: if a due date falls on a Saturday, Sunday or public holiday, the CRA treats the return as on time if it’s filed the next business day.

Law: Excise Tax Act s.238(1) (filing required); Excise Tax Act s.237(1) (instalments).

Input tax credits and records

Input tax credits let you recover the GST/HST you paid on business expenses. They’re where most of the value in a GST/HST return sits, and where most CRA reviews focus.

Law: Excise Tax Act s.169(1) (input tax credits); Excise Tax Act s.169(4) (required documentation); Excise Tax Act s.286(1) (books and records).

What you can and can't claim

  • GST/HST on inventory, supplies, rent, software, phone and internet (business share), professional fees, advertising and equipment
  • The business share of a vehicle, with special limits for passenger vehicles
  • Only 50% of the GST/HST on meals and entertainment, in most cases
  • Nothing on exempt purchases (for example insurance, bank fees, residential rent), because no GST/HST was charged
  • Nothing on personal expenses, or on purchases used to make exempt supplies
  • Nothing on club or recreational facility memberships
  • Only the business-use share of mixed-use costs such as a vehicle, a home office or a phone; for capital property the rules depend on whether business use is more than 50%

What the receipt must show

← Swipe to compare →

Purchase amount (tax included)What your records must show
Under $100Supplier name, date, total paid, and GST/HST charged (or that it's included)
$100 to $499.99All of the above, plus the supplier's GST/HST registration number
$500 or moreAll of the above, plus your name, the terms of payment and a description of what you bought

A bank or credit card statement alone isn’t enough. That’s why we use Dext: you snap the receipt and it’s matched to the transaction in QuickBooks Online or Xero.

Time limits and record keeping

  • Most businesses have four years from the due date of the return for the period the ITC arose in to claim it
  • Keep your books and receipts for six years from the end of the year they relate to
  • Records must be kept in Canada or made available in Canada, and electronic records count
  • We reconcile the GST/HST collected and paid accounts to the general ledger before every return, so small coding errors don't build up across periods

Fixing a mistake on a filed return

If you find an error after filing, you can usually request an adjustment to the return through My Business Account or Represent a Client, or, for some errors such as a missed ITC, claim it on a later return within the time limit. We tell you which route applies.

The quick method and the simplified ITC method

Small businesses can use one of two simpler ways to work out their GST/HST. They’re different, and they’re often confused.

The quick method of accounting lets you remit a fixed percentage of your GST/HST-included sales instead of tracking ITCs on day-to-day expenses. You still claim ITCs on capital purchases such as equipment and vehicles. You can use it if your annual worldwide taxable supplies, including those of associates and including GST/HST, are $400,000 or less, and you elect with Form GST74. Accountants, bookkeepers, lawyers, financial consultants, tax preparers and some others can’t use it.

← Swipe to compare →

Quick method, permanent establishment in OntarioRemittance rate on HST-included sales
Services (for example consultants, trades, cleaners, designers)8.8%
Buying and reselling goods (where cost of goods is at least 40% of sales)4.4%
Credit1% on the first $30,000 of eligible supplies each year

Evergreen note: quick method rates change whenever an HST rate changes. Check CRA’s quick method rates for other provinces and current figures.

A simple example: a consultant in Ontario bills $80,000 + HST/GST, so $90,400 including HST. Under the quick method they remit 8.8% × $90,400 = $7,955.20, less the 1% credit on the first $30,000 ($300), so $7,655.20. Under the regular method they’d remit $10,400 less their ITCs. If their business expenses carry less than about $2,745 of HST, the quick method leaves more in their pocket. We run both before you elect.

The simplified method for claiming ITCs is different: you still remit all the GST/HST you collect, but you can add up your GST/HST-included eligible purchases and multiply by a single fraction (for example 13/113 in Ontario) instead of tracking the tax on each receipt. It’s available if your annual taxable supplies are $1 million or less and your annual taxable purchases are $4 million or less.

Late filing and remittance penalties

Late returns cost 1% of the balance owing plus 0.25% for each full month late, up to 12 months, with interest on top (CRA: penalties and interest).

← Swipe to compare →

What went wrongWhat the CRA charges
Return filed late with a balance owing1% of the amount owing, plus 0.25% of it for each full month late, up to 12 months
Payment late (even if the return was on time)Interest at the prescribed rate, compounded daily
Late or missed instalmentsInterest, and an instalment penalty if the interest is high
Not filing electronically when requiredA failure-to-file-electronically penalty per return
Gross negligence or false statementsA penalty of 25% of the tax involved, with a minimum of $250
Not registering when requiredGST/HST you should have charged, assessed back to the start, plus penalties and interest

Evergreen note: the CRA sets its interest rate every quarter. Check the CRA’s prescribed interest rates page for the current rate.

A late nil return doesn’t trigger the 1% penalty because there’s no balance owing, but it can hold up refunds and the CRA can still issue a demand to file. If you should have charged GST/HST but didn’t, and your customer was a registrant who could have claimed the full amount back (a “wash transaction”), the CRA will consider waiving interest above 4% of the tax not collected, if certain conditions are met (for example, the error was not careless and has been fixed). Under the VDP, wash transactions can get 100% relief. If a penalty came from circumstances outside your control, such as a serious illness, we can ask the CRA for taxpayer relief.

Law: Excise Tax Act s.280(1) (interest); Excise Tax Act s.280.1 (failure to file penalty).

CRA reviews, audits and objections

GST/HST reviews usually focus on ITCs and on zero-rated or out-of-province sales. Here’s how we handle them:

  • ITC reviews. The CRA may ask for receipts before a refund is paid (pre-assessment) or after (post-assessment). We send the invoices and a reconciliation by the deadline in the letter.
  • Audits. We act as your representative through Represent a Client or Form AUT-01, so the auditor deals with us directly.
  • Zero-rated and out-of-province sales. We assemble the shipping documents, contracts and customer addresses that prove the rate you charged.
  • Objections. If you disagree with a reassessment, a Notice of Objection is generally due within 90 days of the notice date. We prepare it so your right to appeal is preserved.

Law: Excise Tax Act s.288(1) (inspections); Excise Tax Act s.296(1) (assessments); Excise Tax Act s.301(1.1) (objection, 90 days).

Catching up on overdue GST/HST returns

Falling behind on GST/HST is common, especially in the first years of a business or after a bookkeeper leaves. The CRA doesn’t forget, though: missing returns hold up refunds, can lead to estimated assessments (arbitrary assessments) that are often higher than what you’d really owe, and eventually to collections action.

Our catch-up process:

  1. Find out where you stand. We pull your CRA account through Represent a Client, list every missing period and any notional assessments.
  2. Bring the books up to date. If your books are behind, our catch-up bookkeeping starts from $1,800 per year.
  3. Prepare every missing return from reconciled books, with the ITCs you can support.
  4. Decide on a voluntary disclosure. If penalties are large and the CRA hasn’t contacted you yet, a VDP application may be the better route.
  5. File, and plan for the balance. If you can’t pay it all at once, we can negotiate a payment arrangement with the CRA for you. That’s a separate service, quoted separately.

Overdue returns where your books are already done are quoted as a fixed fee after we see how many periods are missing.

Law: Excise Tax Act s.238(1) (filing required); Excise Tax Act s.280.1 (failure to file penalty).

Voluntary disclosures (VDP)

The CRA’s Voluntary Disclosures Program lets you correct past GST/HST errors or missing returns in exchange for relief from penalties and some interest. Under the updated program for applications from October 1, 2025, general relief (when the CRA hasn’t contacted you) can waive 100% of penalties and 75% of interest, and partial relief can waive up to 100% of penalties and 25% of interest. The disclosure must be voluntary, complete, involve an error or omission with interest or penalties (or both), include information at least one year past its filing due date, and include payment of the estimated tax owing (or a request for a payment arrangement). Source: CRA: Voluntary Disclosures Program.

Evergreen note: the VDP rules were last changed in October 2025. Check the CRA page above for the current relief levels.

Real estate and new housing rebates, briefly

Real estate is where GST/HST gets expensive to get wrong. A few points every owner should know:

  • The sale of a used home is generally exempt, but a new or substantially renovated home is taxable
  • Commercial property sales are taxable; a registered buyer usually self-assesses the GST/HST instead of paying it to the seller
  • Builders, including individuals who build or substantially renovate a home to sell or rent, can owe GST/HST on the fair market value under the self-supply rules
  • Short-term rentals (under one month at a time) are taxable once you pass the small supplier threshold

Law: Excise Tax Act s.254 (new housing rebate); Excise Tax Act s.256 (owner-built homes rebate).

Digital and platform rules, briefly

Since July 1, 2021, GST/HST applies more widely to online sales:

  • Non-resident sellers of digital products and services to Canadian consumers register under a simplified regime
  • Platform operators (for example Amazon, Airbnb and Etsy) may have to collect GST/HST on sales they facilitate, including short-term accommodation
  • Rideshare and taxi drivers must register from their first fare; some rideshare platforms collect and remit the GST/HST on rides on drivers' behalf, but drivers still have to file their own returns
  • Canadian sellers who use a fulfilment warehouse in Canada and sell through a platform need to know which of them is collecting the tax

If you sell through Amazon, Shopify, Uber, Airbnb or similar, we reconcile the platform reports to your returns so tax isn’t counted twice or missed. See also CRA: digital economy.

Law: Excise Tax Act s.211.1 (digital economy rules, Subdivision E).

Closing your GST/HST account

When you sell your business, wind up a corporation or stop making taxable sales, you close the GST/HST program account. It’s more than a form:

  • Ask the CRA to close the account (Form RC145, or online through My Business Account or Represent a Client)
  • File a final return for the period up to the closing date, plus any missing returns
  • When you stop being a registrant, you're treated as selling your remaining inventory and capital property at fair market value, so GST/HST may be owing on them
  • Pay any balance; a refund on the final return is only issued once every return is filed
  • If you sell the whole business to a registered buyer, a joint election under section 167 (Form GST44) can mean no GST/HST on the sale
  • Small suppliers who registered voluntarily can usually cancel once they've been registered for a year and are back under $30,000; cancelling early can mean paying back ITCs through the deemed-sale rules

Law: Excise Tax Act s.242(1) (cancellation of registration).

Common GST/HST mistakes we fix

  • Claiming ITCs without the supplier's GST/HST number on the receipt
  • Claiming the full HST on meals and entertainment (usually only 50% is claimable)
  • Charging Ontario HST to customers in other provinces, or the reverse
  • Forgetting to report HST on the sale of business assets
  • Returns filed from bank deposits instead of reconciled books
  • Registering late and never charging HST on the sales before registration
  • Missing nil returns, which hold up refunds

Frequently asked questions

When do I need to register for GST/HST?

Most businesses must register once their worldwide taxable supplies, including associated businesses, go over $30,000 in one calendar quarter or over four consecutive calendar quarters. Taxi and rideshare drivers must register from their first fare. You can register voluntarily before then to claim input tax credits.

Should I register voluntarily if I'm under $30,000?

If your customers are mostly businesses and you have real start-up costs, often yes: you claim back the tax on your expenses and your customers claim back what you charge. If you sell mainly to consumers, registering can make you 13% more expensive in Ontario. We’ll run the numbers with you.

Does my side business count toward the $30,000?

Yes, if it’s yours. The test counts the worldwide taxable supplies of you and any associated businesses, so a sole proprietorship and a corporation you control are added together.

How long does registration take?

Registering through Business Registration Online usually gives you a number the same day. Picking the right effective date matters more than speed, because it decides when you must start charging.

What is the HST rate in Ontario?

HST in Ontario is 13%. If you sell to customers in other provinces, the rate depends on where the customer is.

Do I charge HST to customers outside Ontario?

You charge the rate of the customer’s province: 5% GST in Alberta, 15% HST in New Brunswick, 14% in Nova Scotia, and so on. Most exports and many services to non-residents are zero-rated. Always check CRA: GST/HST rates for the current rates.

Do I also need to charge PST?

Only in BC, Saskatchewan, Manitoba and Quebec, which run their own sales taxes with separate registration. We file Manitoba RST returns for clients through TAXcess, and we’ll tell you whether you need a provincial number.

What's the difference between zero-rated and exempt?

Both mean no GST/HST on the sale. Zero-rated sales (basic groceries, most exports) still let you claim ITCs; exempt sales (residential rent, most financial services) don’t.

What is a GST/HST return, and who has to file one?

It’s the report that tells the CRA how much GST/HST you charged and how much you’re claiming back in ITCs, with the difference paid or refunded. Every GST/HST registrant files one for every reporting period, whether a corporation, a sole proprietor or a partnership.

Can I change how often I file?

Yes. You can elect to file more often at any time. Going back to a less frequent period is only possible once your taxable supplies have stayed below the thresholds of your assigned period for 12 months. Elections generally take effect from the start of a fiscal year. Monthly suits businesses that usually get refunds; annual suits those who want the least paperwork.

How often do I have to file GST/HST returns?

It depends on your annual taxable supplies. At $1.5 million or less you file annually by default, from over $1.5 million up to $6 million quarterly, and over $6 million monthly. Smaller businesses can choose to file more often.

When are GST/HST returns due?

Monthly and quarterly returns are due one month after the end of the period. Annual returns are generally due three months after year-end. Individuals with business income and a December 31 year-end file by June 15 but must pay by April 30.

Do I have to file if I had no sales?

Yes. Every registrant files a return for every period, even a nil return. Missing nil returns can hold up refunds and lead to a demand to file.

Should I use the quick method?

Sometimes. The quick method can mean remitting less for some small service and retail businesses, but you generally can’t claim ITCs on most operating expenses. We run the numbers both ways before you choose.

What records do I need to keep for GST/HST?

Sales invoices, purchase receipts that meet the ITC documentation rules, customs documents for imports, contracts for large or zero-rated sales, and the working papers for each return. Keep them for six years from the end of the year they relate to.

What are input tax credits?

Input tax credits let you recover the GST/HST you paid on business expenses. You need proper records, including the supplier’s GST/HST number for most purchases, and we check them before every return.

What happens if I file a GST/HST return late?

If you owe, the CRA charges a penalty of 1% of the balance plus 0.25% per full month late, up to 12 months, and interest on top. If you’ve missed returns, we can catch you up for a fixed fee.

I haven't filed GST/HST returns for years. What now?

Don’t wait for the CRA to estimate them. We pull your CRA account, bring the books up to date and file every missing return. If the CRA hasn’t contacted you, a voluntary disclosure may relieve penalties and part of the interest.

How far back can I claim missed ITCs?

Most businesses have four years from the due date of the return for the period the ITC arose in. We check for missed ITCs when we catch up old periods.

Do I charge GST/HST when I sell real estate?

Selling your used home is generally exempt, but new homes, substantial renovations and commercial property are taxable. Rebates may apply. Book a call before you sign anything.

I sell on Amazon, Airbnb or Uber. Who collects the tax?

It depends on the platform and what you sell. Some platforms collect GST/HST for you, but you may still have to register and file. We reconcile the platform reports to your returns.

How do I close my GST/HST account?

File any missing returns, a final return to the closing date, and ask the CRA to close the account. GST/HST may be owing on assets you still hold when you stop.
