Corporate tax accountant for Toronto corporations

The year-end covers the T2 with Schedule 1 and Schedule 50, the CCA schedule, the small business deduction, T4 or T5 slips for the owner’s pay, and the instalments for the year ahead.

One return, two layers of tax

Active business income eligible for the small business deduction is taxed at a combined 11.2% on a $500,000 business limit. That is 9% federal plus Ontario’s 2.2% lower rate for days after 30 June 2026 (12.2% before; a straddling year is prorated by days). A T2 tax filing consultant in Ontario therefore works from one return, with the provincial layer calculated inside the federal T2 rather than on a separate return.

General income is taxed at 26.5% (15% federal plus Ontario’s 11.5%). The pairing is unusual: Ontario’s small-business rate is the highest among the provinces and its general rate among the lowest, so the gap between qualifying and non-qualifying income is narrower than almost anywhere. It is the figure a T2 corporate tax accountant should model with a growing company before the year end, not after it.

HST instead of two sales taxes

Ontario harmonized its sales tax with the GST: a single 13% HST, administered federally. That means one registration, one return and, critically, a provincial component recoverable as an input tax credit like the federal one, so no provincial sales tax hides in cost of goods sold. Toronto companies often meet the difference only when they start trading with a province that still charges separate PST. Input tax credits covers what is recoverable and the records the CRA expects.

Employer health tax: the rate is chosen before the exemption

Ontario’s employer health tax has a feature that catches employers out. The rate band is set by total Ontario remuneration before the exemption; only then is the exemption subtracted. Crossing a band boundary raises the rate on everything, not just the excess.

The exemption is $1,000,000, and none is available where the employer or its associated group has over $5,000,000 of annual Ontario payroll. Associated employers must file an allocation agreement to share one exemption. Model the cost before hiring, not after.

The registry annual return is a separate filing

An Ontario corporation files its annual return through the Ontario Business Registry within six months of fiscal year end. It is not part of the T2 and produces no tax assessment if missed, so it gets forgotten. It keeps the company in good standing; neglect stays administrative until a lender, purchaser or lawyer asks for a certificate of status. Corporate annual returns explains how it differs by jurisdiction of incorporation.

Dividends out of a Toronto professional or agency corporation

Many Toronto corporations in professional services, design, marketing and technology have a spouse or family member as shareholder. Under the extended tax on split income, their dividends can be taxed at the top marginal rate regardless of other income unless an excluded-share, labour-contribution or age-based exception applies. Those turn on facts, so analyse before declaring the dividend. Tax on split income sets out the exceptions.

Instalments once the corporation is profitable

After its first profitable year, a Toronto corporation generally pays instalments of combined federal and Ontario tax. They are based on the prior year, so a fast-growing company pays too little, then meets a large balance plus interest at filing; a shrinking one overpays unless the estimate is revised. The balance is generally due before the return. T2 deadlines and penalties sets out the dates.

Working with a CPA outside Ontario

EverStone is a fully virtual, one-CPA firm with no Toronto office, branch or local staff. Ontario corporate tax is reported inside the federal return under the same rules wherever the preparer sits, and filed electronically. You give up dropping paperwork at a downtown reception desk; you get the same CPA from first question to filed return.

With a rate change mid-year, the year-end target matters more, and a budget built from the operations fixes it before December.
