Oshawa is Durham Region’s largest city, and its economy still carries the mark of the auto industry. Around the General Motors plant you find parts suppliers, logistics firms, machine shops and the trades that serve them, while Ontario Tech University and Durham College have brought engineering, energy and IT start-ups. Downtown and along Simcoe Street there are restaurants and retailers, and steady housing growth means many landlords and contractors.
I’m Wajahat Ajmal, CPA, FCCA. We work with Oshawa clients by phone, video and email, with cloud bookkeeping in QuickBooks Online or Xero, so distance from our offices does not matter. If you would rather meet in person, our offices in Etobicoke and Mississauga are available by appointment.

Oshawa rules that show up in your books
Oshawa is a lower-tier city in Durham Region, so you deal with the City, Durham Region Health, Ontario and the CRA. Here is what comes up most. (Official sources checked October 2026.)
← Swipe to compare →
| Rule | Who it affects | Official source |
|---|---|---|
| City of Oshawa business licences | Business Licensing By-law 122-2024, in force since November 4, 2024, licenses food shops, vehicle establishments (sales, repair, fuelling and rental), public halls, refreshment vehicles, second-hand dealers, short-term rental operators and other trades. Licence fees are a deductible business cost. | City of Oshawa business licences |
| Durham Region Health food inspections | Food premises in Oshawa are inspected by the Durham Region Health Department under Ontario's food premises rules. | Durham Region Health food safety |
| Rental and short-term rental licences | Oshawa's by-law also covers rental units in its designated rental area and short-term rental operators. Licence costs are deductible against the rental income. | City of Oshawa business licences |
| No municipal land transfer tax | Buyers of Oshawa property pay Ontario land transfer tax only (plus Ontario's non-resident speculation tax for foreign buyers). Toronto's municipal land transfer tax does not apply. | Ontario land transfer tax |
Law: Municipal Act, 2001 s.151(1) (business licensing); Land Transfer Tax Act s.2(1) (Ontario land transfer tax); Health Protection and Promotion Act s.16(1) (food premises).
Ontario tax rules every Oshawa business deals with
← Swipe to compare →
| Rule | What it means | Official source |
|---|---|---|
| HST is 13% in Ontario | Businesses registered for GST/HST. Registration is required once taxable revenue passes $30,000 in a single calendar quarter or over four consecutive quarters. | CRA GST/HST rates page |
| Ontario small business rate: 2.2% from July 1, 2026 | Canadian-controlled private corporations, on the first $500,000 of active business income. With the federal 9%, that is 11.2% combined, prorated for tax years that straddle July 1. | Ontario's corporate income tax page |
| Employer Health Tax (EHT) | Employers with Ontario payroll above the $1 million exemption (shared by associated employers; no exemption once group payroll passes $5 million). Rates 0.98% to 1.95%; annual return due March 15. | Ontario's EHT guide |
| WSIB coverage | Most Ontario businesses that hire workers must register with WSIB within 10 days of hiring their first worker. Some industries are exempt. | WSIB registration |
| Ontario annual return | Every Ontario corporation files an annual return with the Ontario Business Registry. It is separate from the T2. | Ontario Business Registry |
Income above the $500,000 small business limit is taxed at 26.5% combined (15% federal plus 11.5% Ontario). Some older tables online, including the CRA’s, may still show Ontario’s previous 3.2% small business rate; Ontario’s corporate income tax page has the current figure. More in our guides to corporate tax rates in Canada, the Ontario HST rate and GST/HST filing deadlines. If a government page and this summary ever disagree, the government page wins.
Law: Excise Tax Act s.165(2) (HST in participating provinces); Excise Tax Act s.240(1) (registration required); Excise Tax Act s.148(1) (small suppliers); Income Tax Act s.125(1) (small business deduction); Taxation Act, 2007 (Ontario corporate income tax); Employer Health Tax Act s.2(1); Workplace Safety and Insurance Act, 1997 s.75(1) (WSIB registration within 10 days); Corporations Information Act s.3.1 (annual return).
Behind on your books? Catch-up is our speciality
If you are a few years behind, you are not unusual, and it is fixable. We start with your bank and credit card statements, rebuild the oldest year first, then file what is outstanding in the right order: HST returns, T2s and personal returns. If the CRA has sent letters or estimated assessments, we deal with them as part of the job. Penalties and interest keep growing until you file, so waiting rarely helps.
Catch-up work starts from $1,800 per year + HST/GST. See catch-up bookkeeping, back tax filing and a real file in our catch-up case study.
Behind with the CRA? Voluntary disclosure
If you have unfiled returns or income you never reported, the CRA’s Voluntary Disclosures Program (VDP) lets you correct it before the CRA contacts you, with relief on penalties and part of the interest. Many Oshawa owners come to us only after a CRA letter arrives; coming forward first usually gets a better result.
- The law behind it: the CRA can waive or cancel penalties and interest for up to 10 calendar years back under Income Tax Act s.220(3.1) (income tax) and Excise Tax Act s.281.1 (GST/HST). The VDP is how the CRA applies that power to people who come forward.
- Unprompted applications (no CRA contact about the issue yet) normally get 100% penalty relief and 75% interest relief. Prompted applications (after a CRA letter that names a specific error or sets a deadline) normally get up to 100% penalty relief and 25% interest relief. These rules apply to applications received on or after October 1, 2025 (CRA Information Circular IC00-1R7).
- Who qualifies: you must apply before an audit or investigation starts, include all the corrected returns and documents, be at least one year or one reporting period past the due date, and pay the estimated tax or ask for a payment arrangement (CRA’s VDP eligibility page).
We rebuild the missing years, prepare the corrected T1, T2 and GST/HST returns, and file them with Form RC199 so the CRA reviews everything together. Pricing depends on how many years are involved and is part of our catch-up bookkeeping quote, which starts from $1,800 per year + HST/GST. The CRA decides each application case by case, so relief is never guaranteed.
Law: Income Tax Act s.150(1) (filing deadlines); Income Tax Act s.162(1) (late-filing penalty); Income Tax Act s.161(1) (interest on unpaid tax); Income Tax Act s.152(7) (assessment not dependent on return); Excise Tax Act s.238(1) (GST/HST returns).

Yes. We prepare SR&ED claims end to end: the eligibility review, project write-ups, the T661 claim form and the T2 filing, plus support if the CRA reviews the claim. Pricing depends on the claim and is quoted after a free consultation.
Yes. Under By-law 122-2024, vehicle establishments, including sales and repair services, need a City of Oshawa licence. We record the fee as a business expense.

Yes, it is our speciality. We rebuild the books from bank statements, file the overdue HST returns and T2s in the right order (personal T1 returns are quoted separately), and deal with any CRA letters. Catch-up work starts from $1,800 per year + HST/GST.
From July 1, 2026, a Canadian-controlled private corporation pays 11.2% combined (9% federal plus 2.2% Ontario) on the first $500,000 of active business income, prorated for tax years that straddle July 1.
Once your taxable revenue passes $30,000 in a single calendar quarter or over four consecutive quarters. You can register voluntarily before that, which lets you claim input tax credits on your costs.
Most Ontario businesses that hire workers must register with WSIB within 10 days of hiring their first worker, though some industries are exempt. Our payroll service includes WSIB reporting.

The VDP application is quoted separately after a free review. Any catch-up bookkeeping starts from $1,800 per year + HST/GST.
Not always. If the letter names a specific error or sets a deadline, your application is treated as prompted and normally gets up to 100% penalty relief and 25% interest relief. Once an audit or investigation has started on that issue, the VDP is closed to you, so it is worth acting quickly.
