Form CPT30 is the CRA election that lets an employee stop paying Canada Pension Plan contributions. You can use it if you're at least 65 but under 70 and already receive a CPP or QPP retirement pension. It takes effect on the first day of the month after you give your employer a copy, and the same form restarts contributions later if you change your mind.
This guide follows the CRA's CPT30 E (26) and its CPT30 form page, as of October 2026.
Who can use it
- You're an employee aged at least 65 but under 70. The earliest you can sign is the day after your 65th birthday.
- You're receiving a CPP or QPP retirement pension.
- You haven't already made a change, stopping or restarting, in this calendar year.
All three have to be true. If you're not yet drawing your pension, you can't elect to stop, so the order matters: apply for the retirement pension first. The application form for that is ISP-1000.
When not to use it
The form isn't for Quebec Pension Plan contributions; to stop those you go to Retraite Quebec. It also isn't for you if all your income is from self-employment. In that case your choice is made on Schedule 8 of your return, or Form RC381 if you worked in more than one province.
When you do file a CPT30, it covers all your pensionable employment income, including any self-employment earnings you also have.
How to stop contributions
- Fill in Part A (your details) and Part B (eligibility), then Part C. Leave Part D blank.
- Sign it in pen or ink. A handwritten signature is required, and you can't backdate it.
- Give each current employer a copy of the signed form, proof of age such as a driver's licence or passport, and proof you get a CPP or QPP pension, such as your notice of entitlement or a benefit statement.
- Send the original to Employer Services, Winnipeg Tax Centre, Box 14000, Winnipeg MB R3C 3M2.
- Keep a copy for future employers.
The first time you fill it in, the date you enter must be the date you give the copy to your employer. If your employer offers to send the original to the CRA for you, that's accepted too.
When it takes effect
Your election starts on the first day of the month after the date you give your employer the copy. Your employer stops deducting from the first pay in the following month. If you underpaid before that date, your employer can adjust your contributions.
So timing matters. Hand the copy over at the end of a month and the change starts days later; hand it over on the 1st and you'll wait a full month.
A worked timeline
Here's how the dates fit together. Say you turn 65 in March and you're already receiving your CPP retirement pension. The earliest you can sign is the day after your birthday. If you sign and hand your employer a copy later that month, the election takes effect on April 1, and your employer stops deducting from the first April pay. If they deducted too little before then, they can still adjust it.
Then say you change your mind in October. You can't restart in the same calendar year you stopped, so the earliest you can sign Part D is January of the next year.
Changing jobs doesn't reset it
The election stays valid when you move jobs or take a second job, so don't fill in a new form. Give a copy of the original to every new employer. If you go back to an old employer, for seasonal work for example, check they still have it on file.
Changing your mind
You can only make one change a calendar year. If you stopped contributions this year, you wait until at least January before you can restart. To restart, fill in Parts A, B and D, give a copy to each employer promptly and send the original to Winnipeg.
Contributions restart on the first day of the month after you give your employer the revocation. Your employer starts deducting from the first pay dated in the month after you signed Part D, as long as you give them enough notice.
Lost your copy?
If you've already sent the original and need a copy back, write to the Speciality Services Section at the Winnipeg address. If you've revoked an election since you last worked for a previous employer, give them a copy of the revocation too, so they start deducting again.

How long it lasts
An election stays in force until you revoke it or turn 70, so the form only matters for the years between 65 and 70. For this year's contribution rules see the CPP contributions guide.
The verdict
If you're 65 to 69, working and already drawing CPP, a CPT30 stops the deductions from the month after your employer gets it. Get your pension in place first, sign in ink, give every employer a copy with proof of age and pension, and send the original to Winnipeg. Remember you only get one change a year.
