Budget-Friendly T4A Slip Preparation for Canadian Businesses

For the 2026 tax year, federal rates are 14% on the first $58,523 of taxable income, 20.5% from there to $117,045, 26% to $181,440, 29% to $258,482, and 33% above that. Each rate applies only to the income inside its own band, so moving into a higher bracket does not raise the tax on the income below it. Provincial or territorial tax is added on top.

The basic personal amount is a non-refundable credit that shelters a base level of income from federal tax, so income below it carries no federal tax. The amount is indexed every year, and the enhanced portion is phased out across the second-highest federal bracket, so taxpayers in the top bracket receive only the base amount. Each province and territory sets its own version. On Form TD1 you claim it so your employer withholds less; claim it with one employer only, or too little tax is withheld.

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.

It should not. A T4A reports fees for services before sales tax, so the box amount is meant to exclude GST/HST. Some payers get this wrong and include the tax, which overstates the income the CRA sees against your name. Compare the slip with your own invoices and ask the payer for an amended slip if it is inflated. Report revenue net of GST/HST on your T2125 and account for the tax collected on your GST/HST return.

The consumer bears it; the business collects it. A registered vendor adds GST/HST to taxable sales, holds it in trust and remits it to the CRA, recovering the tax it paid on its own inputs through input tax credits. So businesses in the chain are generally neutral, while the final buyer pays. Some purchasers, including certain Indigenous purchases on reserve, governments and diplomats, have relief, and low-income households receive the quarterly GST/HST credit.

The claim code is the number payroll uses to turn the credits you claimed on your federal and provincial personal tax credits returns into the tax withheld from each pay. A higher code means larger credits claimed and less tax deducted; the lowest code means no credits, so tax comes off every dollar. Most people sit at the code matching the basic personal amount, which is $16,452 federally for 2026. File a fresh return when your situation changes.

A flat monthly cash allowance for a phone is taxable employment income and appears on the T4. If the employer instead pays the carrier directly, or reimburses the business portion of a bill on receipts, and the plan is reasonable and mainly for work, there is normally no taxable benefit; personal use of a basic plan the employer already pays for is generally accepted. Keep records showing the business purpose.

Tax legislation is the written law that imposes and administers tax: federally the Income Tax Act and the Excise Tax Act, plus each province's own statutes and the municipal bylaws behind property tax. A change usually begins as a budget announcement, is drafted into a bill, passes Parliament and takes effect on royal assent. Regulations and CRA guidance sit beneath the statutes and explain administration without replacing them. Some proposals are administered before they pass, and a few never do.

Sometimes, depending on the type. A non-refundable credit reduces tax payable and can only take it to zero, so once you owe nothing, extra non-refundable credits add nothing to a refund. A refundable credit is paid out even when no tax is owing, so it does increase what you get back. Deductions work differently again, lowering taxable income before the rates apply. If you already owe nothing, look for refundable credits and benefits instead.

The CRA charges compound daily interest on any balance still unpaid after the payment deadline, and it keeps accruing until the balance is cleared. Where the return itself was filed on time there is no separate late-payment penalty, only interest. For the 2025 personal tax year the payment deadline was 30 April 2026, including for self-employed filers who had until 15 June 2026 to file. Municipal property tax is a different system, with charges set by your municipality.

You pay tax of 1% per month on the highest excess amount in the account for each month the excess is there, and this remains the rule for 2026. Unlike an RRSP there is no buffer, so the tax starts on the first dollar over. It keeps running until you withdraw the excess or new January room absorbs it, and you have to file a TFSA return. The CRA can waive the tax for a reasonable error.

Line 10400 is other employment income: employment amounts that do not arrive on a T4. Typical entries are tips and gratuities, casual or occasional earnings, foreign employment income, net research grants, wage-loss replacement payments and royalties from your own work. It is added to your T4 employment income in the total income section. Nothing was usually withheld at source on these amounts, so reporting tips here often creates a balance owing at filing time.
