Low-Cost Corporate Reorganization Tax Planning for Canadian Businesses

Corporate tax is income tax a corporation pays on its own profits, reported on a T2 return that is separate from the owner's personal return. Both federal and provincial tax apply. For 2026 the federal small business rate is 9% on the first $500,000 of active business income and the federal general net rate is 15%, with the province adding its own rate on top. An unincorporated business pays no corporate tax; its profit is taxed in the owner's hands.

A tax specialist prepares and files returns, works out how the rules apply to your particular facts, and deals with the CRA on reviews, audits and objections. On the planning side that covers timing income, choosing between salary and dividends, structuring a sale of a business, or correcting a filed year through an adjustment request. Fees vary with complexity, so get the price in writing before work starts and confirm whether CRA follow-up is included.

Different taxes run on different clocks. A corporation files its T2 six months after the fiscal year end, with the balance due two months after year end, or three months for an eligible CCPC claiming the small business deduction, and pays instalments monthly or quarterly once its tax is more than a small amount. GST/HST returns are monthly, quarterly or annual depending on revenue. Payroll deductions are remitted at least monthly, and sole proprietors pay quarterly instalments.

From its first profitable year: there is no tax-free start-up period. A sole proprietor reports business income on a T2125 with the T1 and pays with the personal return. A corporation files a T2 six months after each fiscal year end, with the balance due two months later, or three months for an eligible small business corporation. GST/HST registration is separate and begins once taxable revenue passes $30,000, and payroll remittances start with the first employee.

If you are incorporated, you can take salary, dividends, or a mix of both. Salary is deductible to the corporation, builds RRSP room and CPP entitlement, and requires payroll registration and regular remittances. Dividends need no payroll but come out of after-tax corporate income and create no RRSP room. Sole proprietors and partners simply draw money and pay tax on the business profit. The right mix depends on your cash needs and the corporation's tax position, so model both.

RM identifies the GST/HST program account inside a CRA business number. A business number is nine digits, then a two-letter program code and a four-digit reference, so 123456789 RM0001 is your first GST/HST account. Other codes cover payroll, corporate income tax and import-export. Use the RM account when filing or remitting a GST/HST return, and quote the full fifteen characters so the payment lands on the right account.

File as soon as you can. If you owe, the late-filing penalty is 5% of the balance owing plus 1% for each full month the return is late, to a maximum of 12 months, and compound interest runs on the unpaid amount. If you are due a refund there is no late-filing penalty, but benefit and credit payments such as the Canada child benefit can pause until the return is assessed. The 2025 deadline was 30 April 2026.

There is no federal credit for paying rent. Relief, where it exists, is provincial and usually income tested. Ontario folds rent into the Ontario Energy and Property Tax Credit, paid through the Ontario Trillium Benefit; Manitoba has a renters tax credit; Quebec has a solidarity tax credit with a housing component. You claim these on the provincial part of your return, so keep rent receipts and your landlord details. Rent paid for a home office is claimed separately.

Canada RIT stands for refund of income tax, so it is your assessed T1 refund or an adjustment paid after a reassessment. Canada FPT covers federal-provincial-territorial credits, most often the GST/HST credit and related provincial amounts, so it is not your income tax refund. Canada PRO is a provincial program payment, which in Ontario is the Ontario Trillium Benefit. Match the amount and date against your notice of assessment or the benefit payment dates in CRA My Account.

A private creditor cannot take a refund from the CRA directly. CRA itself can apply your refund against tax you owe, and under federal set-off it can be redirected to other government debts such as defaulted student loans or benefit overpayments. Once the money reaches your bank account it is an ordinary asset, so a collection agency holding a court judgment and a garnishment order can seize it there. Unpaid tax is not reported to credit bureaus, although CRA can register a lien.

Each province sets its own top bracket, which sits on top of the federal top bracket, so the highest combined marginal rate depends on where you live, and both rates and thresholds are adjusted each year. Look up the current combined table for your province rather than relying on a single national figure. It is a marginal rate: only the income above the threshold is taxed at it, never your whole income.

There is no federal credit for children's sport, arts or activity fees, and Ontario's own children's activity credit ended years ago, so hockey, dance and camp registration is not deductible on your return. A few provinces still run their own activity credit, so check your province's information on canada.ca. Day camps and after-school care that let you work may instead qualify as child care expenses, which are normally claimed by the lower-income spouse.
