The tax slip for your Canada Pension Plan disability benefits is the T4A(P), officially titled the Statement of Canada Pension Plan Benefits. Service Canada mails it by the end of February each year, and it shows the total disability income paid to you during the calendar year along with any federal tax that was withheld. Because CPP disability payments are taxable under section 56 of the Income Tax Act, the numbers on this slip go straight onto your T1 return.1Department of Justice Canada. Income Tax Act – Section 56
What the T4A(P) Records
One T4A(P) covers every type of CPP benefit paid to you in the year: retirement, survivor, disability, children’s, and post-retirement, each in its own numbered box.2Canada Revenue Agency. T4A(P) Statement of Canada Pension Plan Benefits The CRA already has a copy, and it matches what you file against what the slip shows, so the amounts you enter need to line up exactly.
Before you do anything else, check that the tax year and your Social Insurance Number on the slip are correct.
The Three Boxes That Matter
If you receive only CPP disability, three boxes carry all the information you need.
Box 16 — Disability benefit. The gross disability amount paid to you during the year. For 2026, the maximum monthly CPP disability payment is $1,741.20, so Box 16 could show up to roughly $20,894 for a full year at the maximum rate.3Government of Canada. Canada Pension Plan Disability Benefits – Overview
Box 20 — Taxable CPP benefits. The total of all CPP benefits paid to you, combining Boxes 14 through 19. This is the figure you actually report as income. If disability is your only CPP benefit, Box 20 will match Box 16.4Canada Revenue Agency. Line 11400 – CPP or QPP Benefits
Box 22 — Income tax deducted. The federal income tax already withheld from your monthly payments. It acts as a credit against what you owe.2Canada Revenue Agency. T4A(P) Statement of Canada Pension Plan Benefits
You may also see Box 17 (children’s benefits paid for your dependent children) or Box 18 (death benefits). Both are already folded into Box 20, so you don’t add them separately.
Where Each Box Goes on Your Return
Three transfers, and you’re done with the CPP portion of your return:
- Box 20 goes on line 11400. This is your actual CPP income for the year.4Canada Revenue Agency. Line 11400 – CPP or QPP Benefits
- Box 16 goes on line 11410. This is informational only. The amount is already included in Box 20, so you are not adding it to your income a second time.2Canada Revenue Agency. T4A(P) Statement of Canada Pension Plan Benefits
- Box 22 goes on line 43700, where it offsets your total tax owing. If it exceeds what you owe, the difference comes back as a refund.2Canada Revenue Agency. T4A(P) Statement of Canada Pension Plan Benefits
The filing deadline for most individuals is April 30.5Canada Revenue Agency. Due Dates and Payment Dates – Personal Income Tax Most tax software can pull these numbers in through Auto-fill My Return, which imports directly from CRA records and eliminates transcription errors. The CRA generally has slip data ready for auto-fill by mid-March.6Canada Revenue Agency. Auto-fill My Return Compare the auto-filled figures against the slip in front of you before you submit.
Getting Your Slip or Replacing a Lost One
Paper T4A(P) slips are mailed by the last day of February. If you want it sooner, or if yours went missing, sign in to My Service Canada Account and choose “View my tax slips.” Electronic slips for the current year and the past six years are available there, and the CRA treats digital slips as official documents with the same weight as paper.7Canada.ca. Canada Pension Plan in MSCA
If your paper slip never arrives, you can request a replacement through the online portal or by phone. Update your mailing address with Service Canada before slip season if you have moved recently.
Why Box 22 Might Show Zero
Tax is not automatically withheld from CPP disability payments.8Canada.ca. Managing Your Taxes Unless you asked for withholding, Box 22 will show zero and you will owe the full tax on your disability income when you file. For someone at or near the maximum benefit, that can mean several thousand dollars due on April 30.
You can start or change withholding three ways: complete Form ISP3520CPP (Request for Voluntary Federal Income Tax Deductions) and mail it to Service Canada, adjust it through My Service Canada Account, or call Service Canada directly.8Canada.ca. Managing Your Taxes Setting it up early in the year is the simplest way to avoid a bill at filing time.
If Your Slip Includes a Retroactive Lump Sum
CPP disability applications often take months to process, and once approved, Service Canada usually pays a lump sum covering the months back to your eligibility date. The whole retroactive amount lands on one T4A(P) in the year you receive it, which can push you into a higher tax bracket even though the money relates to earlier years.
For qualifying retroactive lump-sum payments of $3,000 or more, the CRA can calculate your tax as if the income had been spread across the years it actually relates to. You pay whichever is lower: the tax on the lump sum in the current year, or the tax that would have applied if the payment had been allocated to prior years.9Canada.ca. Qualifying Retroactive Lump-Sum Payments Form T1198 is used for this calculation. The payment must relate to the 1978 tax year or later, and you must have been a Canadian resident during the years covered. Check whether your slip came with a breakdown showing how the lump sum allocates across prior years, and consider a tax professional if the retroactive period spans several years.
Two Things to Check While You’re Filing
Being approved for CPP disability does not automatically qualify you for the Disability Tax Credit. The DTC is a separate non-refundable credit that requires its own application on Form T2201, with a qualified medical practitioner completing Part B to certify your impairment.10Canada Revenue Agency. How to Apply – Disability Tax Credit Form It is worth checking your eligibility: the federal disability amount was $10,138 for the 2025 tax year.11Canada Revenue Agency. Claiming the Credit – Disability Tax Credit (DTC) The CRA recommends submitting the DTC application before you file to avoid assessment delays.
If you worked at all during the year, that income appears on separate slips (T4 or T4A) alongside your T4A(P), and it is taxable in the normal way. It can also affect your benefits. In 2026, once your gross earnings reach $7,400, you must contact Service Canada to report the work. Earnings between $7,400 and $20,971.45 may prompt a review, and earnings of $20,971.45 or more will likely end your disability benefits.3Government of Canada. Canada Pension Plan Disability Benefits – Overview The thresholds apply to gross income, not net.
