Is it too late to file Form T1213 for this year?
Not necessarily, but part of the benefit has already gone. The authorisation reduces tax withheld from pay or pension payments going forward, from the pay period after your employer or payer receives the CRA letter. It is not applied backwards to pay you have already received. A request made part-way through the year therefore reduces withholding for the remaining pay periods only. The rest is recovered in the ordinary way when the return for that year is filed and the deductions and credits are claimed. If the request has slipped, send it anyway, and put next year's in before the first pay period.
What is the penalty for filing Form T1213 late?
There is none for the request itself. It is a request for authorisation, not a return, so lateness costs cash flow rather than a penalty. The penalty exposure sits on the income tax return for the year. For the 2025 tax year the CRA late-filing penalty is 5 per cent of the balance owing plus 1 per cent of that balance for each full month the return is late, to a maximum of 12 months. For the same tax year it is 10 per cent plus 2 per cent per full month, to a maximum of 20 months, where the CRA issued a demand to file and had charged a late-filing penalty in any of the three preceding tax years. The penalty does not compound. Interest compounds daily on the unpaid balance.
Can my employer reduce my withholding before the CRA letter arrives?
No. Payroll is required to withhold on the statutory basis until it holds the authorisation, and a payroll department that reduces tax on the strength of a draft calculation is taking the exposure itself. Most will refuse, correctly. The authorisation identifies the payer and the period it covers, and payroll applies it from the pay period after it receives a copy. If you move between employers during the year, the authorisation does not travel with you. A fresh request is needed for the new payer.
Do I need to file Form T1213 every year?
Treat it as a yearly exercise. The authorisation is given for a period of withholding rather than indefinitely, so a fresh request is needed for each new one. Because the CRA reviews the supporting figures before approving, a request sent after the period has begun costs the pay periods that pass while it is considered. Where the deductions are stable year on year, such as a recurring foreign tax credit or carrying charges on an investment loan, the practical answer is a standing calendar entry that puts the request in before the first pay period, with the previous year's assessment attached as evidence that the pattern is real.
Can a foreign tax credit support a reduction of Canadian tax at source?
It can, and this is the case where the request matters most. A Canadian resident taxed first in another country on the same employment or pension income may carry a foreign tax credit large enough that the Canadian return produces a refund every year. Left alone, that means tax deducted at source all year and returned months after the year ends. The request asks the CRA to take the credit into account in setting withholding, so the money stays with you in the meantime. The CRA will want to see the foreign withholding evidence and the basis of the credit, not an estimate.
If the request is approved late, do I lose the refund?
No. Nothing is forfeited by a late request. The deductions and credits are claimed on the return as usual and the over-withheld tax comes back as a refund. What a late request costs is the use of your own money for the months it sat with the payer, which for someone with a large and predictable credit can be a substantial sum carried at no interest. That is the whole point of the exercise. The tax outcome is the same either way, and the timing is not.
Is the sale of foreign property taxable where I live?
For a resident, yes — worldwide gains are taxable, and the gain is computed in your own currency, so the exchange rate at purchase and at sale changes the number even when the local-currency price did not move. The country where the property sits usually taxes it too, often with a withholding or clearance step before closing, and that tax becomes a credit. A principal residence relief may apply to a home abroad on the same terms as one at home. See principal residence and foreign property.
Branch or subsidiary — which should we use to expand?
A branch keeps one taxpayer: results consolidate at home, losses are usable sooner, and the exposure is that the branch is a permanent establishment whose profit the host country taxes, sometimes with a branch tax on repatriation. A subsidiary is a separate taxpayer with limited liability and local rates, at the cost of withholding on dividends home and transfer pricing on everything between them. The deciding facts are usually expected losses, liability and exit plans. See branch against subsidiary.
