Economical Corporate Investment Income Planning for Canadian Businesses

Most tax saving comes from a short list of levers: contributing to an RRSP or a spousal RRSP, holding investments inside a TFSA, FHSA or RESP so growth is sheltered, claiming every deduction and credit you actually qualify for, and splitting income where the rules allow, such as pension income splitting. Business owners add expense timing and salary versus dividend planning. Order matters, so decide before year end rather than at filing time.

The HST is a single sales tax blending the federal 5% GST with a participating province's own sales tax, collected and administered by the CRA. For 2026 it is 13% in Ontario, 14% in Nova Scotia since 1 April 2025, and 15% in New Brunswick, Newfoundland and Labrador, and Prince Edward Island. A registrant charges HST on taxable supplies, claims input tax credits on its purchases, and remits the difference on one return. Elsewhere you charge the 5% GST plus any separate provincial tax.

Start with total income from every source for the year, including employment, self-employment, investments and pensions. Subtract the deductions you qualify for, such as RRSP contributions, child care costs, union dues and deductible employment expenses, to reach net income. Take off any further deductions that apply at the next stage, losses carried forward among them, and what remains is taxable income, the figure the brackets are applied to. Credits reduce the tax calculated on that figure rather than the income itself.

Wait for your notice of assessment, then use Change my return in CRA My Account, ReFILE through approved tax software, or mail a T1-ADJ with supporting documents. Adjustments are allowed for the current year and a set number of earlier years; the CRA's Change my return page states the limit. Explain each line you are changing and attach the receipts. A change takes longer to process than an original return, and interest on any extra tax runs from the original due date.

No single revenue line makes a business small. Tax rules use their own tests: the federal small business rate of 9% applies to the first $500,000 of active business income of a Canadian-controlled private corporation for 2026, and GST/HST registration becomes mandatory once taxable revenue passes $30,000 over four consecutive calendar quarters or within a single quarter. Lending and grant programs set separate revenue or employee-count limits of their own.

Start with the structure. An unincorporated business reports on form T2125 inside your personal T1, due 15 June 2026 for the 2025 year, with any balance still payable by 30 April 2026. A corporation files a T2, due six months after its fiscal year end. Either way, reconcile your bookkeeping first, separate business from personal spending, keep records for six years, and claim capital purchases through depreciation rather than as an outright expense.

There is no set percentage. A refund is simply the difference between the tax withheld from your pay or paid in instalments and the tax your return actually calculates, so someone over-withheld with large RRSP contributions gets a lot back while someone with side income owes. Your notice of assessment shows the arithmetic. Online returns for the 2025 tax year are generally processed in about two weeks; a non-resident return can take up to sixteen.

A bed tax is the informal name for a municipal or provincial tax on short-term accommodation, charged on a hotel, motel or short-term rental night. Municipalities in Ontario, Alberta, British Columbia and elsewhere levy it under their own legislation, usually as a percentage of the room charge, and rates and names differ by city. GST/HST applies on top. Operators collect and remit it to the city or province, not to the CRA. Check your municipality's bylaw for the current rate.

TRACS is Alberta's Tax and Revenue Administration Client Self-Service portal. Corporations and other filers use it to submit and view Alberta provincial returns, make payments, check balances and authorise representatives. It matters because Alberta does not have the CRA administer its corporate income tax: an Alberta corporation files a federal T2 with the CRA and a separate Alberta corporate return with the province through TRACS. Quebec runs a comparable system.

Before. A price reduction the seller gives at the time of sale, such as a store-funded coupon, a percentage off or a marked sale price, reduces the consideration, and GST/HST is then charged on the discounted amount shown on the receipt. Manufacturer coupons and rebates paid after the sale are handled differently, and the tax may be calculated on the pre-discount price. The receipt shows the taxable amount the tax was computed on.

Personal rate and bracket changes almost always apply from 1 January of the tax year, so 2026 rates apply to income earned in 2026 and show up on the return you file in 2027. Federal 2026 brackets start at 14%. Corporate changes can land mid-year: Ontario's small business rate is 3.2% and falls to 2.2% effective 1 July 2026, and a fiscal year straddling that date is prorated between the two rates.

Tax revenue is the money governments receive from taxes: personal and corporate income tax, GST/HST and provincial sales taxes, payroll contributions, excise duties and property taxes. It funds health care, schools, roads, defence, pensions and benefit programs, and it is also used to shape behaviour through targeted credits and levies. In Canada the CRA collects most federal and provincial income tax and GST/HST, while municipalities collect property tax directly.
