The Northwest Territories levies no territorial sales tax, so only the 5% federal GST applies and there is one filing stream. Residents who live there for at least six consecutive months beginning or ending in the year can also claim the Zone A northern residents deduction. The NWT levies a 2% payroll tax on employee remuneration, withheld from wages and remitted by the employer.

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.
Sign in to CRA My Account and open the tax returns section, which lists your assessed returns, notices of assessment and reassessment, and carry-forward amounts for earlier years. You can also download a proof of income statement, request a copy by phone, or ask whoever prepared the return for you. Keep your own copy and the supporting records for six years from the end of the tax year they relate to.
Gather your slips and receipts, then use NETFILE certified software and its auto-fill feature to pull in the slips the CRA already holds. Add what the CRA cannot see, such as self-employment income, medical expenses, donations and child care, review the summary line by line, and file electronically. For the 2025 tax year the deadline was 30 April 2026, or 15 June 2026 where you or your spouse were self-employed, with any balance still due 30 April 2026.
Income tax starts once taxable income passes the basic personal amount, and a separate provincial or territorial amount applies on top, so the break-even point shifts every year with indexation and differs by where you live. Look up the current amounts on the CRA site or in the year's return package. Credits for tuition, disability, pension income or dependants push the point higher. Filing can still be worthwhile or required with no tax owing, for benefits and credits.
A TD1 Personal Tax Credits Return tells your employer which personal credits to build into your income tax withholding, so the right amount comes off each pay. You normally complete a federal TD1 and a provincial or territorial TD1 when you start a job. File a fresh pair whenever your situation changes, for instance a new dependant, tuition, or a second employer, where you should not claim the basic personal amount twice.
The federal goods and services tax is 5% in 2026, and has been since it dropped from 6% to 5% on 1 January 2008. You pay the 5% on its own in Alberta, the Northwest Territories, Nunavut and Yukon. In British Columbia, Manitoba, Saskatchewan and Quebec it sits alongside a separate provincial tax, and in the five participating provinces it is folded into the HST rate.
Canada taxes residents on their worldwide income for the calendar year, reported by the taxpayer on a T1 return. Employers and other payers withhold tax through the year, and the return reconciles what was withheld against what is owed, producing a refund or a balance to pay. Rates are progressive and layered, federal plus provincial. Deductions lower taxable income and credits lower the tax itself. The 2025 return was due 30 April 2026.
Contact your municipality’s tax or revenue office and ask for a reissued bill; most cities also let you view and pay it in an online property tax account set up with your roll number. Not receiving the bill does not cancel the obligation or stop late-payment charges, so ask for the amount and due dates straight away. Update your mailing address, and check whether your lender already pays the tax through your mortgage.
There is no set number of months. Property tax is handled as a closing adjustment: your lawyer prorates the year's tax to the closing date, so you reimburse the seller for any paid period falling after closing, or take a credit for tax the seller has left unpaid. Where the lender collects tax with the mortgage payment, it may also want an opening cushion. The statement of adjustments shows the exact amount for your deal.
You owe a balance when the tax withheld or paid during the year came to less than your total tax for the year. Common causes are two employers each applying the basic personal amount, self-employment or rental income with no withholding at all, investment income, RRSP withdrawals taxed at a flat rate, and CPP or OAS with little tax taken off. For the 2025 tax year the balance was due 30 April 2026. Extra withholding or instalments stops it recurring.
