What is Form T1172?
Accumulated income payments (AIPs) are the investment earnings paid out of an RESP to the subscriber when they aren't used for a beneficiary's education. They are reported in box 040 of a T4A, included in income on line 13000, and also attract an additional tax. Form T1172, Additional Tax on Accumulated Income Payments from RESPs, is how you calculate that additional tax for any year from 1999 on.
Part A is for original subscribers and people who stepped into their shoes in the situations the form lists: you can reduce the AIPs subject to the tax by RRSP, PRPP or SPP contributions you deducted, up to the $50,000 lifetime limit. Part B is for everyone else, and taxes the whole AIP. Part C applies a 60% adjustment for people who lived in Quebec on December 31 of that year.
FileIt asks which part applies and whether you lived in Quebec, takes your AIP and contribution amounts, and works out every remaining line on the CRA's own PDF (edition T1172 E (25)). The result is saved in the person's vault folder. You attach it to your return yourself; FileIt doesn't file anything.

How to fill out Form T1172, step by step
1 Choose Part A or Part B
Part A covers the original subscriber, someone who acquired the subscriber's rights on a marriage breakdown, the spouse or common-law partner of a deceased original subscriber where there's no subscriber left, and someone who acquired a public primary caregiver's rights. Everyone else uses Part B.
2 Part A – lines 1 to 10
Enter your total AIPs (line 1), the contributions you deducted (line 2) and amounts used in earlier years (line 5). FileIt takes the lesser of lines 1 and 2, limits it by what's left of $50,000, and applies 20% to the rest.
3 Part B – lines 11 to 13
Enter your total AIPs; the additional tax is 20% of the whole amount.
4 Part C – Quebec
If you lived in Quebec on December 31, the tax from line 10 or 13 is multiplied by 60%. The result goes on line 41800.
Common mistakes to avoid
- Counting contributions you didn't deduct on line 20800, or more than your deduction limit.
- Leaving out amounts used on earlier T1172 forms, which shrink the $50,000 lifetime limit.
- Using Part A when you became a subscriber after the original subscriber died.
- Forgetting Part C as a Quebec resident.
- Missing the balance-due date for the additional tax.
After you fill it out
Print the PDF from your FileIt vault, sign and date it, and attach a copy to your return for the year you received the AIPs. Enter the line 10, 13 or 16 amount on line 41800. FileIt doesn't file it for you.
Pay the additional tax by the balance-due date for your regular tax, usually April 30 of the next year (for a trust, 90 days after its year end). Keep the form in your vault: next time you'll need its line 7 for line 5.

What is the additional tax on AIPs?
An extra 20% tax on the AIPs that aren't sheltered by deducted RRSP, PRPP or SPP contributions, on top of the regular tax on the AIP as income.
Where does the result go?
On line 41800 of your income tax and benefit return for the year you received the AIPs.
Why does Quebec get a different amount?
Part C multiplies the tax by 60% for people who lived in Quebec on December 31 of that year, as printed on the form.
Do I still need this if the promoter transferred the AIP to my RRSP?
Yes. The T1171 only stops tax being withheld; the T1172 works out whether any additional tax is owed.
