Pocket-Friendly Bookkeeping Workflow Automation for Canadian Businesses

For the 2025 tax year the filing and payment deadline is 30 April 2026. If you or your spouse carried on a business, the return itself is due 15 June 2026, but any balance owing is still due 30 April 2026. Interest runs on unpaid amounts after the payment deadline, and a late-filed return with a balance owing also attracts a late-filing penalty. Filing on time keeps benefit and credit payments flowing.

A balance owing means the tax withheld or paid by instalments during the year came to less than the tax your return calculates. Common causes are two employers each withholding as though theirs was your only job, self-employment or gig income with nothing withheld, investment or rental income, an RRSP or RRIF withdrawal where only the base amount was held back, pension and OAS payments taken without deductions, or a benefit you have to repay.

Divide the total by one plus the rate. At Ontario's 13% in 2026, a $113 tax-included total is $113 divided by 1.13, or $100 before tax and $13 of HST. Use 1.14 in Nova Scotia, 1.15 in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and 1.05 where only the 5% GST applies. Multiplying the total by 13 over 113 gives the Ontario tax directly.

Most bank charges are exempt rather than zero rated. Financial services such as account fees, interest, loan arrangement and most transfers fall in the exempt category, so no GST or HST is charged and there is no input tax credit to recover. Some bank services are taxable, including safety deposit boxes and certain administrative or advisory fees, and those do carry tax and an input tax credit. Check each statement line instead of assuming.

Most corporations pay no capital tax at all in Canada. The federal large corporations tax and the general provincial capital taxes were phased out, so an ordinary operating company is outside the system entirely and needs no exemption. What survives is provincial capital tax on financial institutions such as banks, trust and loan companies and insurers, each province setting its own threshold and deduction. If your corporation is not a financial institution, check the relevant provincial ministry of finance page to confirm.

Yes, and it is usually worth doing. Filing with little or no income keeps benefits flowing, because the GST/HST credit, the Canada Child Benefit and provincial credits are all recalculated from a filed return. It also lets you carry forward tuition and other unused amounts. Report EI benefits, severance and any RRSP withdrawals: those slips are income even in a year you were not working. New RRSP room needs earned income.

Telecommunications services are taxable, so the bill carries 5% GST plus whatever provincial tax applies where the service is supplied: 7% PST in British Columbia, 6% in Saskatchewan, or the provincial part folded into HST at 13% in Ontario and 14% in Nova Scotia since 1 April 2025. Alberta and the territories see only the 5% GST. A business can recover the GST or HST portion as an input tax credit; PST is not recoverable.

Yes. Provincial and territorial governments generally pay GST/HST on their purchases and recover it through their arrangements with the federal government, so invoice a government department the way you would any other customer. A small number of buyers hold documented relief, including certain Indigenous purchases and specific certificate arrangements, and that relief has to be evidenced when the sale is made. Keep the documentation with the invoice, because the CRA will otherwise look to you for the tax.

You cannot write off the income itself, but you deduct the costs of earning it. Common current expenses are mortgage interest (not principal), property tax, insurance, utilities you pay, condo fees, advertising, property management, and repairs that maintain the property. Improvements that better the property are capital and depreciated instead. Only the rented portion counts where you also live there. Keep invoices for six years from the end of the tax year they relate to.

No fixed multiplier works, because income tax is progressive and CPP and EI stop at annual ceilings, so the deduction rate changes as pay rises. The practical method is iterative: pick a gross figure, run it through the CRA's payroll deductions online calculator, compare the net to your target and adjust until they meet. Payroll software runs the same loop automatically. Where an employer guarantees a fixed net amount, the employer absorbs the tax and the calculation is redone each period.

Reportable income is every amount you have to show on your return, which is wider than the amount you finally pay tax on. It takes in employment income, self-employment and side income, tips, interest, dividends, capital gains, rent, pensions and most benefits, slip or no slip. Foreign income is reportable too, even where tax was already paid abroad. Report everything first, then claim the deductions and credits that reduce what is taxable and what you owe.

Deductible contributions are those to a registered retirement savings plan, a registered pension plan and a first home savings account. Contributions to a tax-free savings account, a registered education savings plan or a registered disability savings plan are not deductible, since the benefit comes from sheltered growth and government grants instead. Charitable and political contributions produce non-refundable credits rather than deductions, and amounts contributed above your available room can attract a monthly penalty tax.
