What does T1213 change?
Form T1213 asks CRA to authorize reduced tax deductions at source for eligible deductions or credits not covered by TD1. If implemented by payroll, more cash can reach you during the year instead of through a later refund. It does not create an extra deduction or reduce annual tax twice.

Illustrate relief across remaining pays
Start with a reviewed tax-relief estimate. Subtract relief already reflected in withholding and choose the number of covered payments. This is an allocation illustration, not an approved payroll reduction.
Tax relief, sooner
Timing onlyTax dollars, not the RRSP contribution or interest expense. Use a reviewed tax estimate. The default is illustrative.
Only payments covered by the relevant authorization. This does not estimate approval timing.
Relief already received
Subtract amounts already received through payroll so the same relief is not allocated twice.

- Already received through withholding
- $0.00
- Relief allocated to remaining pays
- $3,000.00
This divides an entered tax estimate across payments; it does not reproduce a CRA letter or payroll formula. Actual reductions depend on authorization, implementation dates and tax available to withhold. CPP/QPP, EI/QPIP and annual tax liability are unchanged by timing alone. Receiving relief now can reduce a later refund.

Start with an eligible deduction and an authorization
Review the current CRA form and supporting-document instructions. Apply for the relevant period, wait for the letter of authority where required, and provide the authorization to payroll. A calculator is not approval, and an expected deduction is not itself permission to change withholding. Processing and payroll implementation dates vary.

RRSP contributions through payroll are a separate case
CRA’s employer guide describes how an eligible RRSP contribution withheld and remitted directly by the employer can reduce remuneration subject to income-tax deductions. Personally made RRSP contributions may instead require a letter of authority. Confirm the actual arrangement with payroll; do not count relief already reflected in your cheque again.

Give Québec its own treatment
Revenu Québec has a separate reduction process using form TP-1016-V. A CRA authorization should not be assumed to cover Québec provincial withholding. The timing illustration does not split federal and Québec authorizations or reproduce either payroll calculation.

A timing example, not a larger refund
If a reviewed annual tax-relief estimate is $3,000, and $400 has already reached payroll, $2,600 remains to allocate. Dividing that amount over 26 covered payments illustrates $100 per pay. The annual tax effect is still $3,000. Reducing withholding during the year generally leaves less excess tax available for a later refund, all else equal.

How the illustration works
Calculation version ca-illustrations-v1. No financial inputs are sent to a tax authority or Analytics.
Allocate an amount that is already estimated
Remaining relief equals the entered total estimate less relief already received through withholding. Amounts are rounded to cents. Each covered pay gets the whole-cent quotient; leftover cents are allocated one at a time to the earliest payments. This preserves the total exactly, including small amounts.
For example, $0.26 over 52 payments gives $0.01 on 26 payments and zero on the others. It does not create negative adjustments or lose cents.
Authorization comes from the authority
Neither this allocation nor the RRSP tax estimate predicts the terms of a letter, the available payroll withholding, or your actual next cheque. A deductible expense and its tax reduction are different amounts. Use the official forms and employer process; the site does not submit requests or collect tax records.
Common questions
Should I enter my RRSP contribution as tax relief?
No. Enter estimated tax dollars saved, not the deductible contribution or expense. The RRSP calculator estimates the tax reduction from a deduction using reviewed 2026 Canadian rules. Your authorization and actual payroll implementation may differ.
Does T1213 create additional tax savings?
No. For an unchanged eligible deduction and tax situation, it changes when relief reaches you. Receiving relief through withholding and claiming the deduction on the return do not create two separate tax savings.
Does this predict my next paycheque?
No. It evenly allocates an entered remaining tax-relief estimate. Authorization terms, start dates, payroll calculations and the tax otherwise withheld determine the actual reduction. It does not change CPP/QPP or EI/QPIP contributions.
Can DollarMath submit the form or store my tax records?
No. Read and submit forms through the official tax-authority process. This page does not collect a SIN, employer details, authorization letter or tax documents. Comparisons stay in your browser.
Can I save plans or use my results in Excel or Google Sheets?
Yes. Save named plans in this browser without an account, then reopen, compare, rename or duplicate them. JSON backups can restore editable plans after local validation and a review step. Download a spreadsheet for typed inputs, results and detailed schedules where available, then open it in Excel or import it into Google Sheets yourself. Workbooks are snapshots, not live calculator formulas. Plans and files are not encrypted; clearing browser data can remove device plans. Nothing is automatically uploaded or synchronized.
