Formula & methodology

Formula used

claim amount = BPA + age amount (if 65+) + disability amount (if eligible) + spousal + dependants + credits
tax saving = claim amount × lowest marginal rate, federal + provincial
recommended withholding = bracket_tax(taxable income) − tax saving

Every TD1 claim amount is valued at the lowest marginal tax rate (federal 14%, provincial varies) and subtracted from the tax otherwise owed on your bracket-computed tax — this mirrors how the CRA's actual TD1 worksheet converts claim amounts into reduced withholding.

Step-by-step calculation

1. Taxable income
Annual salary minus RRSP, pension, union dues, and other authorized deductions.
2. Tax without claims
Federal and provincial bracket tax computed on taxable income, with no credits applied.
3. Federal claim amount
Basic personal amount + age amount (if 65+) + disability amount (if eligible) + spousal amount + dependant amounts + tuition/medical/donation credits.
4. Provincial claim amount
Same structure using your province's basic personal amount and claim amounts.
5. Tax saving and recommended withholding
Each claim amount is valued at its jurisdiction's lowest marginal rate and subtracted from the no-claims tax to reach the recommended annual withholding.

Limitations

Dependant and provincial spousal amounts use simplified fixed figures rather than each province's exact TD1 worksheet formula.
Does not model the age amount's income-based phase-out at higher income levels.
Tuition, medical, and donation amounts are valued at the lowest marginal rate here; medical and donation credits actually use different CRA formulas above certain thresholds.

This page is educational. It applies published rates and thresholds to the figures you enter and shows the arithmetic behind the result. It is an estimate, not a tax determination: your actual liability depends on circumstances this calculator does not collect, and only the relevant tax authority — or an accountant who can see your full position — can confirm what you owe.

Help & FAQs

Frequently Asked Questions

Clear answers to common questions to help you use this calculator confidently.

What is the TD1 form and how does it affect my paycheque?

Tap to view the answer

TD1 (Personal Tax Credits Return) tells your employer which personal tax credits you qualify for — basic, age, disability, spousal, dependants — so they withhold the correct amount of income tax. More credits claimed means less tax withheld and higher take-home pay throughout the year.

What is the basic personal amount for 2026?

Tap to view the answer

The federal basic personal amount is $16,452 for 2026. Provincial basic amounts vary by province — Ontario's is $12,989. Every taxpayer can claim both.

What's the difference between the federal and provincial TD1?

Tap to view the answer

The federal TD1 reduces federal tax withholding; the provincial TD1 (TD1-QC in Quebec) reduces provincial tax withholding. Both use similar credit types (basic, age, disability, spousal), but the dollar amounts differ by jurisdiction.

Do self-employed people need to fill out a TD1?

Tap to view the answer

No. TD1 is for employees who receive a T4 slip and have tax withheld by an employer. Self-employed individuals calculate their own tax and make instalment payments directly to the CRA.

What happens if I claim too much on my TD1?

Tap to view the answer

Claiming credits you're not entitled to means too little tax gets withheld, which can leave you with a balance owing — plus possible interest — when you file. Review your TD1 whenever your marital status, age, or eligibility for credits changes.

Understanding the TD1 and Payroll Withholding

What the TD1 form does

The TD1 Personal Tax Credits Return tells your employer how much tax to withhold from your pay. You complete a federal TD1 and a provincial one when you start a job, and whenever your circumstances change.

The form lists the non-refundable credits you expect to claim. Payroll converts your total claim into a reduced withholding amount, so a larger claim means less tax off each cheque. It does not change the tax you ultimately owe — that is settled on your return — it changes the timing. Getting the TD1 right means your withholding matches your actual liability, so you neither lend the government money for a year nor face a bill in April.

The basic personal amount and the two-job trap

Everyone claims the basic personal amount: $16,452 federally for 2026, plus a provincial amount — about $12,989 in Ontario. For most people with one job, this is the only line they fill in, and that is correct.

The trap arrives with a second job. If you claim the basic personal amount at both employers, each withholds as though its salary is your only income, so both shelter the same first $16,452 and both assume you are in a low bracket. Combined, your real income sits higher and not enough tax was withheld. Claim the basic personal amount at your highest-paying job only, and tick the box indicating more than one employer on the second form.

Credits worth claiming on the form

Several credits are worth declaring rather than waiting for a refund. The age amount applies from 65 — $9,208 federally for 2026. The disability amount is $10,341 if you have an approved Disability Tax Credit, and an unused portion transferred from a dependant can be claimed too.

The spouse or common-law partner amount applies where your partner's income is low, and the eligible dependant amount is available to single parents supporting a child. Tuition can be claimed by a student in the year it is paid. Each of these reduces withholding immediately. If you are entitled to them and do not claim them here, you simply get the money back a year later instead.

TD1 credits versus T1 deductions

The TD1 handles non-refundable credits only. It does not cover deductions such as RRSP contributions, childcare expenses, or support payments, and it does not cover credits claimed at year end like medical expenses or charitable donations.

If you have large ongoing deductions, the tool is form T1213, Request to Reduce Tax Deductions at Source. Submit it with supporting documentation and, if approved, the CRA authorises your employer to withhold less. This is genuinely valuable for someone making substantial monthly RRSP contributions outside payroll: rather than waiting until spring for a $4,000 refund, you receive roughly $330 more in each monthly cheque and can invest it a year earlier.

Asking for extra tax to be withheld

The TD1 also lets you request additional tax be deducted each pay period, and this is one of its most useful features.

It suits anyone with income their employer knows nothing about: self-employment on the side, rental income, investment income, or a second job. Rather than facing a large balance in April and possibly quarterly instalment requirements, you smooth it across the year. It also helps people who consistently owe a small amount. The CRA charges interest on balances owing and can require instalments if you owe more than $3,000 in the current year and either of the two preceding years, so pre-empting it is worthwhile.

When to update the form

A TD1 is not a one-time task. Update it when you turn 65 and become eligible for the age amount, when a Disability Tax Credit is approved, when you marry or separate, when a spouse's income changes substantially, when you start or stop a second job, or when a dependant's circumstances change.

Employers are required to keep the most recent form on file, and if you do not submit one they must withhold using the basic personal amount alone. That is the safe default for them but often the wrong answer for you. A five-minute update after a life change is usually the difference between an accurate paycheque and a surprise the following April.

Formula & methodology

Formula used

claim amount = BPA + age amount (if 65+) + disability amount (if eligible) + spousal + dependants + credits
tax saving = claim amount × lowest marginal rate, federal + provincial
recommended withholding = bracket_tax(taxable income) − tax saving

Step-by-step calculation

1. Taxable income
Annual salary minus RRSP, pension, union dues, and other authorized deductions.
2. Tax without claims
Federal and provincial bracket tax computed on taxable income, with no credits applied.
3. Federal claim amount
Basic personal amount + age amount (if 65+) + disability amount (if eligible) + spousal amount + dependant amounts + tuition/medical/donation credits.
4. Provincial claim amount
Same structure using your province's basic personal amount and claim amounts.
5. Tax saving and recommended withholding
Each claim amount is valued at its jurisdiction's lowest marginal rate and subtracted from the no-claims tax to reach the recommended annual withholding.

Limitations

Dependant and provincial spousal amounts use simplified fixed figures rather than each province's exact TD1 worksheet formula.
Does not model the age amount's income-based phase-out at higher income levels.
Tuition, medical, and donation amounts are valued at the lowest marginal rate here; medical and donation credits actually use different CRA formulas above certain thresholds.
