The RRSP contribution limit for 2026 is 18% of your earned income from last year, to a ceiling of $33,810, plus any room you didn’t use before. If a pension plan at work took a bite, subtract that too. Most people never hit the ceiling. Your own number is the one that matters, and it’s printed on your notice of assessment.
How is your RRSP contribution limit worked out?
There are three pieces. Start with the lesser of 18% of last year’s earned income and the dollar limit. Add unused room from earlier years. Then take away your pension adjustment, which is the value of the pension you earned at work. What’s left is your deduction limit for the year.
Earned income here isn’t the same as total income, and the CRA has its own definition of it. Your notice of assessment prints the final room figure, so use that one rather than doing the sums from memory. The table below is for getting a feel for the size of the number, not for filing.
How do you find your own limit?
Pull out the notice of assessment from your latest return. It states your RRSP deduction limit for the coming year, which is the figure the CRA will hold you to. If the paper copy is gone, you can find the same number in your CRA account. The CRA’s page on contributing to an RRSP has a link for where to find deduction limits and another for what contributions do to them.
Say Tom in Moncton filed his 2025 return in March and wants to top up his RRSP in the fall. He opens the notice, finds a limit of $13,200, and sees from his bank statements that he’s already put in $9,000 this year. He has $4,200 of room left, so a $5,000 lump sum would put him $800 over. That’s inside the $2,000 buffer, but he couldn’t deduct the extra $800, so he sends $4,200 instead.
If you haven’t filed for a year or two, file first. The CRA builds your room from the returns it has, so missing returns can mean missing room. Your T4 helps too: the pension adjustment sits in box 52, which tells you what workplace pension did to your number.
What does the limit look like at different incomes?
We ran four cases through the RRSP calculator, each with no unused room from earlier years.
| Last year’s earned income | Pension adjustment | Room for 2026 |
|---|---|---|
| $50,000 | $0 | $9,000 |
| $90,000 | $0 | $16,200 |
| $90,000 | $5,000 | $11,200 |
| $250,000 | $0 | $33,810 |
The $50,000 row is plain arithmetic (18% of $50,000). The others are the calculator’s output. You’d need earned income of about $187,834 to reach the cap.
Why does the pension adjustment matter so much?
Because it comes straight off the top. A worker earning $90,000 with a workplace pension worth $5,000 a year has $5,000 less room than a neighbour on the same pay with no pension. That’s $11,200 against $16,200 in our table.
Ask your employer’s plan administrator for the figure if you don’t know it. A wrong guess shows up later as a surprise on your notice of assessment, when it’s too late to adjust what you put in.
What is the RRSP contribution limit worth in tax?
Take the $90,000 earner again. Putting $10,000 into an RRSP cuts Ontario income tax from $17,034 to $14,069. That’s $2,965 back, so the real cost of the $10,000 is $7,035. At $250,000 of income the same $10,000 saves $4,982, since the deduction comes off at a higher rate.
Notice that the limit controls what you may put in, and your tax rate decides the value of each dollar. Two people with the same room can have very different refunds, because someone in a higher bracket saves more on each dollar than someone in a lower one. The marginal tax rate calculator shows your rate, and the tax refund calculator shows where the refund lands.
Where people get the limit wrong
The most common slip is using last year’s dollar limit. For 2025 it was $32,490, and for 2026 it is $33,810, so a figure pulled from an old article can be off by more than $1,000.
The second is forgetting that room carries forward. If you skipped contributions for three years, that room is still there, and it stacks on top of this year’s. The third is leaving the pension adjustment out of the sums when you have a workplace plan. It shrinks your room, and the CRA counts it whether or not you noticed.
Remember that the room is a ceiling on the deduction, not a promise to use it. You can contribute now and claim later, in a year with a higher rate. What could the money grow to by retirement? The retirement savings calculator gives a rough answer. Even a few bucks from every paycheque adds up over a few decades.
The sources behind this page
The dollar limits for 2025 and 2026 and the 18% rule come from the Canada Revenue Agency‘s table of RRSP and related limits and its page on how contributions affect your deduction limit. The room amounts in the table are results from our own calculator, which assumes no unused room from earlier years. We didn’t find a CRA page that prints the income needed to reach the cap, so that figure is our arithmetic. This site is independent and isn’t connected to the CRA.
Frequently asked questions
What is the RRSP contribution limit for 2026?
The dollar limit is $33,810. Your own limit is 18% of last year's earned income up to that cap, plus unused room, minus any pension adjustment.
Where do I find my personal RRSP room?
On your latest notice of assessment, and in your CRA My Account.
Does unused room expire?
No. Room you don't use carries forward to later years.
Does a workplace pension reduce my room?
Yes. The pension adjustment on your T4 reduces your room the following year.
Is there any slack if I go over?
The CRA allows a $2,000 buffer of over-contribution without penalty. Above that, the tax is 1% a month on the excess.
