# Request to Reduce Tax Deductions at Source

## Overview

When a Quebec court orders spousal support, your employer continues deducting tax as though your full salary is taxable income — because, without instruction from the Canada Revenue Agency, they have no mechanism to do otherwise. The result is overwithholding all year and a refund the following April, a cash-flow pattern that strains the post-separation budget when it is tightest.

The **T1213, Request to Reduce Tax Deductions at Source**, corrects this. It is a federal authorization request filed with the **Canada Revenue Agency (CRA)** that directs your employer or payer to reduce the income tax withheld from each paycheque, reflecting deductions and credits that the standard **Form TD1, Personal Tax Credits Return** cannot accommodate. For separated individuals across Montreal and Quebec, the most frequent uses are spousal support payments, child care expenses, and RRSP contributions made outside of payroll. The T1213 addresses federal tax only; Quebec provincial withholding requires a separate filing with Revenu Québec.

## What Does the T1213 Do?

The T1213 is an authorization request, not a tax return. When the CRA approves it, the agency issues a letter directing your employer or payer to reduce income tax withheld from your salary or lump-sum payments for the calendar year specified on the form. The reduction reflects deductions identified in Part 3 — amounts deductible under the _Income Tax Act_ but absent from your TD1, including spousal support, child care expenses, RRSP contributions, employment expenses, and medical expenses.

The form does not create an entitlement. It allows an entitlement you already hold to reduce your tax burden before year-end rather than producing a refund after you file.

> ⚠️ The T1213 reduces only federal income tax deducted at source. Montreal-area residents seeking relief on provincial withholding must file a separate source deduction request directly with Revenu Québec.

## When Do You Need a Request to Reduce Tax Deductions at Source?

A T1213 is appropriate any time you have deductions or credits that will reduce your federal tax owing but are not reflected on your TD1. In a family law context, common triggers include:

- Paying **spousal support** under a Quebec court order or written separation agreement. Child support payments are not deductible and cannot be claimed here.
- Incurring significant **child care expenses** paid from employment income.
- Making RRSP contributions directly — outside of payroll deductions — as part of a post-separation financial plan.
- Carrying employment expenses supported by a signed Form T2200 from your employer.

The T1213 must be filed each year. If your deductible spousal support payments remain the same or increase year over year, you may submit one combined request covering two consecutive years by providing a completed form for each.

> ⚠️ Only payments meeting the _Income Tax Act_ definition of a "support amount" — paid periodically under a court order or written agreement, with the recipient having full discretion over use — qualify. Child support does not meet this definition and cannot be included.

## Who Must File the T1213?

The individual taxpayer — not a lawyer, accountant, or employer — completes and signs the T1213. The certification in Part 4 is a personal attestation. An authorized representative may submit the completed form through the CRA's Represent a Client portal, but the underlying information and signature remain the taxpayer's responsibility.

Two conditions must be satisfied before filing: all prior-year income tax and benefit returns must have been filed and assessed by the CRA, and any outstanding balances must have been paid in full.

> ⚠️ The CRA will not approve a T1213 if you carry unpaid balances or have unfiled prior-year returns. Both must be resolved before submitting.

## How Do You File a T1213?

The T1213 is available from the CRA website. Complete all four parts: identification (Part 1), type of income being reduced — salary or lump sum (Part 2), itemized deductions and credits with supporting documents (Part 3), and the certification signature (Part 4).

Submit the completed form and all supporting documents online through the CRA's My Account portal — select "Submit documents," choose the topic "Contact Centre and International Correspondence," and upload — or by mail or fax to:

📍 Sudbury Tax Centre, PO Box 20000 Station A, Sudbury ON P3A 5C1 Fax: 418-562-3368 or 1-833-697-2401

There is no filing fee. The CRA issues an authorization letter upon approval, which you provide to your employer to adjust withholding for the remainder of the tax year.

> ⚠️ Submit as early in the calendar year as possible. An approval in January allows withholding to be reduced for the full year; one issued in October benefits only the final paycheques. Overwithholding from earlier months becomes a refund the following April, not a mid-year correction.

## What Documents and Information Do You Need?

Required supporting documents depend on which deductions you are claiming. For the most common family law applications:

- **Spousal support:** A copy of the court order or written separation agreement; **Form T1158**, Registration of Family Support Payments (if not previously filed with the CRA); and the recipient's name and social insurance number.
- **Child care expenses:** Details on a separate sheet or a completed **Form T778**, Child Care Expenses Deduction.
- **RRSP contributions:** Details or a copy of the payment arrangement contract. Exclude contributions already deducted from your pay by your employer.
- **Employment expenses:** A signed **Form T2200**, Declaration of Conditions of Employment, and **Form T777**, Statement of Employment Expenses.
- **Medical expenses:** An itemized list of each expense and the related amount.

Keep originals for your records; the CRA requires copies only.

> ⚠️ For spousal support claims, Form T1158 is required if the support arrangement has not been previously registered with the CRA. Omitting it is among the most common causes of processing delays on T1213 filings involving support payments.

## How Long Does a T1213 Request Take, and Is There a Fee?

There is no fee to file a T1213. The CRA does not publish a guaranteed processing timeline, and turnaround varies with submission volume. Online filing through My Account is generally faster than mailing a package to the Sudbury Tax Centre. Build several weeks of processing time into your submission date.

> ⚠️ The CRA authorization must reach your employer before adjusted withholding can begin. Account for this lead time when planning your submission, particularly if you need the adjustment to take effect early in the tax year.

## What Are the Family Law Implications of Support Payment Deductions?

Under the _Income Tax Act_, spousal support qualifies as a deductible "support amount" when it is paid periodically pursuant to a court order or written agreement and the recipient has discretion over its use. Child support paid under orders or agreements established after April 30, 1997 is neither deductible by the payer nor taxable in the recipient's hands — a design embedded in federal law since 1997 amendments to the _Income Tax Act_.

This distinction shapes separation negotiations. The net cost of deductible spousal support is meaningfully lower than the gross amount for higher-income earners, a key factor in family proceedings across Quebec. Separated individuals in Montreal and across Quebec often negotiate whether a payment structure will be characterized as spousal support, child support, or a hybrid specifically because the tax treatment differs fundamentally.

Informal or verbal support arrangements do not qualify under the _Income Tax Act_. A Quebec Superior Court order, or a notarized separation agreement, is the threshold document required.

> ⚠️ The T1213 does not confer eligibility — it depends on qualifying legal documentation already being in place. If your support arrangement has not been formalized in a court order or written agreement, the CRA will disallow the deduction regardless of what the form states.

## A Real-World Example

> 📌 **Parent A** lives in LaSalle and earns $90,000 per year. Under a Montreal Superior Court support order, **Parent A** pays **Parent B** $1,500 per month in spousal support — $18,000 annually. **Parent A**'s employer withholds income tax as though the full $90,000 is taxable. In January, **Parent A** files a T1213 with the CRA, attaching the support order, Form T1158, and **Parent B**'s social insurance number. The CRA approves the source deduction reduction request based on the $18,000 deduction. Once the authorization letter reaches **Parent A**'s payroll department, monthly withholding drops to reflect the reduced taxable income. **Parent A** receives approximately $420 more per month — money that had previously been overwithhheld and returned only the following April. The adjustment provides meaningful cash-flow relief during the period when post-separation financial pressure is typically highest.

## Frequently Asked Questions

### Can I use the T1213 to reduce withholding on child support payments?

No. Child support payments made under orders or agreements established after April 30, 1997 are not deductible under the _Income Tax Act_ and cannot be included on a T1213. Only spousal support meeting the statutory definition of a "support amount" qualifies. Characterizing child support as spousal support on a T1213 to claim a deduction exposes you to CRA reassessment and potential penalties.

### Do I need to file a new T1213 every year?

Generally, yes. The CRA reviews each request annually to confirm the claimed deductions will generate a refund based on that year's income. One exception applies: if your deductible spousal support payments remain the same or increase from one year to the next, you may submit a combined request covering two consecutive years by providing a completed T1213 for each year.

### Is there a Quebec provincial form I also need to file?

Yes. The T1213 covers only federal income tax withheld for the CRA. Quebec residents who want to reduce provincial income tax deducted at source must file a separate request with Revenu Québec. Both filings are typically required to achieve meaningful reduction in total withholding.

## Common Mistakes to Avoid

- **Claiming child support as a deductible support amount.** Child support is not deductible under current federal law. Including it results in that portion of the claim being disallowed and may subject the entire request to heightened review.
- **Omitting Form T1158 for unregistered support arrangements.** If the support order or agreement has not been previously registered with the CRA, Form T1158 must accompany the T1213. Missing it causes delays and frequently leads to the support deduction being denied outright.
- **Filing too late in the year.** An approval in November corrects only a handful of paycheques. Submitting in January or February gives the adjustment its full impact.
- **Including employer-deducted RRSP contributions.** Part 3 excludes RRSP amounts already withheld and remitted by your employer. Including them overstates the deduction and will cause the CRA to reduce or reject the waiver.
- **Submitting while carrying prior-year debts.** Outstanding balances or unfiled returns are automatic grounds for rejection. Clear these first.

## When to Get Legal Help

The T1213 is straightforward when a court order is clear, deductions are well-documented, and the support arrangement is formally registered. Complexity arises in hybrid support structures, lump-sum settlements, and situations where a Quebec support order is currently under variation proceedings. Whether a payment qualifies as deductible spousal support rather than non-deductible child support is not always obvious, and mischaracterizing it creates CRA reassessment exposure.

If your separation has not been formalized in a court order or notarized agreement, you may not be eligible to claim the deduction at all. A Montreal family lawyer can confirm whether your underlying documentation supports a T1213 filing — and, if it does not, can identify what steps are needed to get there.

## Speak with a Family Lawyer

The T1213 depends entirely on the legal quality of the underlying support arrangement. A small mischaracterization between spousal and child support, or an informal arrangement without written documentation, can result in a CRA reassessment and loss of the deduction after you have already planned your cash flow around it. Goldwater Droit advises separated individuals in Montreal and across Quebec on ensuring that support agreements are correctly characterized, formally documented, and structured to support both the federal T1213 filing and the corresponding Revenu Québec request.
