An RRSP withholding tax refund happens when the flat rate your financial institution deducted from your withdrawal was higher than your actual tax rate for the year. To claim it, you file a T1 return, report the withdrawal as income, and credit the tax already withheld against your total tax owing. If the withholding overshot your real liability, the Canada Revenue Agency (CRA) refunds the difference.
Why the Withholding Is Often Too Much
Every RRSP withdrawal counts as taxable income for the year you take it out. Your bank deducts tax upfront at a flat rate set by the size of the withdrawal, then sends you the rest. That flat rate has nothing to do with your personal tax situation. Your real tax bill on the withdrawal depends on your marginal rate, which is set by your total income for the year. When the flat rate is higher than your marginal rate, you have overpaid, and the return is what recovers the difference.
The Withholding Rates That Got Applied
For Canadian residents outside Quebec, the federal withholding on a lump-sum RRSP withdrawal is:
- 10% on amounts up to $5,000
- 20% on amounts from $5,001 to $15,000
- 30% on amounts over $15,000
These rates are mandatory and your institution cannot waive them at the time of withdrawal.1Canada Revenue Agency. Tax Rates on Withdrawals Quebec residents see lower federal withholding at the same tiers (5%, 10%, and 15%) because Revenu Québec collects separate provincial withholding on top; contact your institution or Revenu Québec for the combined amount. Non-residents face a flat 25% federal withholding, subject to reduction under a tax treaty.2Canada Revenue Agency. Non-Residents and Income Tax
Check your withdrawal amount against these tiers to confirm which rate hit your account.
How the Refund Amount Is Worked Out
At tax time, the withdrawal gets added to the rest of your income for the year, and your total tax is calculated on the combined figure using graduated brackets. The federal brackets begin at 15% on roughly the first $57,000 of taxable income in 2026, then move through 20.5%, 26%, 29%, and 33%.3Canada Revenue Agency.

An example makes the math obvious. Someone who withdrew $20,000 during a low-income year triggered 30% withholding, meaning $6,000 went to the CRA upfront. If their marginal federal rate on that withdrawal turns out to be 15%, the federal tax actually owed on it is closer to $3,000, and the $3,000 gap comes back as a refund (adjusted for provincial tax and credits).1Canada Revenue Agency.

The reverse also happens. Someone earning $150,000 in employment income who then pulls $20,000 from an RRSP may find the 30% withholding was not enough, because the withdrawal sits in a bracket taxed at 26% or 29% federally with provincial tax layered on top. That person owes a balance instead of getting a refund. If your other income for the year was low, a refund is likely. If you were already deep into a middle or upper bracket, prepare to pay more.
The T4RSP Slip and Where the Numbers Go
Your financial institution issues a T4RSP slip for any year you took money out of an RRSP. It usually arrives by late February, either in the mail or through CRA’s My Account portal. Two boxes drive the refund calculation:
- Box 22: the gross amount withdrawn before deductions
- Box 30: the income tax the institution withheld
Box 22 goes on line 12900 of your T1 as RRSP income. Box 30 counts toward the total tax you have already paid for the year.4Canada Revenue Agency. T4RSP Statement of RRSP Income5Canada Revenue Agency. Withdrawing From Your Own RRSPs Tax software handles the arithmetic once you enter both figures alongside your other income slips. Keep a copy of the T4RSP in case the CRA asks for verification.
Withdrawals made under the Home Buyers’ Plan or Lifelong Learning Plan are a separate story. Those programs have no withholding tax and no income inclusion when you follow the repayment schedule, so no refund question arises from them.
Filing Method and Processing Times
File electronically through NETFILE for the fastest turnaround. The CRA targets processing 95% of electronic returns within four weeks and paper returns within eight weeks, though returns pulled for review take longer.6Canada Revenue Agency. Check CRA Processing Times
After processing, the CRA sends a Notice of Assessment showing the final calculation and any refund amount or balance owing.7Canada Revenue Agency. Notices of Assessment If you have direct deposit registered with the CRA, the refund lands in your account soon after. Otherwise it comes by cheque, which adds mailing time.
If You Are a Non-Resident: Section 217
For non-residents, the 25% withholding is normally the final tax obligation, so there is nothing to reconcile on a Canadian return. Section 217 of the Income Tax Act offers a route around that. If your Canadian-source income for the year was relatively low, you can elect to file a Canadian return under Section 217 and be taxed at graduated resident rates on the withdrawal instead of the flat 25%. When the graduated calculation comes out lower, the CRA refunds part or all of the withholding.8Canada Revenue Agency. Electing Under Section 217 The election is not automatically better; running the numbers both ways before filing is the only way to know.
One Thing the Refund Does Not Give Back
The refund recovers the overpaid tax. It does not restore the RRSP contribution room you used up. Outside the Home Buyers’ Plan and Lifelong Learning Plan, withdrawn RRSP room is gone permanently, and so is the tax-sheltered growth that money would have generated over the years it stayed invested. Getting the withholding back is a real win. Losing the room is a separate cost that no return will refund.
