RRSP Contribution Room: Reading Your CRA Notice

It's a Saturday in late spring, and Joanna is at the kitchen table in her Burnaby townhouse with a mug of coffee and a brown envelope from the Canada Revenue Agency. Her partner Rey is out at their son's soccer game. She flips past the first page of the notice of assessment, lands on a box labelled "RRSP Deduction Limit Statement," and frowns. There's a "deduction limit." There are "unused contributions." Her bank's app shows something else again. So how much can she actually put in this year?

If that's you, you're in good company. Two numbers that sound alike mean slightly different things, and mixing them up is how people end up overcontributing or leaving room on the table. Let's walk through how to read the statement, using the CRA's own wording.

Deduction limit vs RRSP contribution room: the short version

Your RRSP deduction limit is the maximum you can deduct on your tax return for a given year. The CRA explains that it's built from your unused deduction room at the end of the previous year, plus the lesser of 18% of your previous year's earned income or that year's annual dollar limit, then reduced by any pension adjustment (PA) and net past service pension adjustment (PSPA), and increased by any pension adjustment reversal (PAR) (CRA, How contributions affect your RRSP deduction limit).

Your RRSP contribution room, in everyday terms, is how much new money you can put in without creating an excess. That's usually not the same as the deduction limit, because money you've already contributed but haven't deducted yet uses up some of that room.

A simple way to think about it:

• Deduction limit = the ceiling the CRA calculated for you
• Unused contributions = money already sitting in your RRSP that you haven't claimed as a deduction yet
• Room for new contributions ≈ deduction limit minus unused contributions

That last line is the one most people miss.

The annual dollar limits, checked against the CRA table

The 18% calculation is capped by a yearly dollar amount. According to the CRA's published table of registered plan limits, the RRSP dollar limit is $32,490 for 2025, $33,810 for 2026 and $35,390 for 2027 (CRA, MP, DB, RRSP, DPSP, ALDA, TFSA limits and the YMPE). The CRA also confirms "for 2025, the annual limit is $32,490" on its deduction limit page.

Here's the part that trips people up. Those dollar figures are a cap on the new room you earn, not the amount you personally get. If your earned income last year was $80,000, 18% of that is $14,400, which is well under the cap, so $14,400 is the most new room that year's income could add. Then your pension adjustment, if you're in a workplace pension plan, takes some of it back. Teachers, nurses, and many municipal and provincial employees around Metro Vancouver often see a much smaller number than they expect for exactly this reason.

Where to find your number

The CRA lists a few places to look (CRA, Where can you find your RRSP deduction limit):

• The RRSP Deduction Limit Statement on your latest notice of assessment or reassessment
• Your CRA online account (My Account)
• Form T1028, Your RRSP Information, which the CRA sends if something changed or the statement wasn't on your notice
• The CRA's automated phone service

The same page adds a useful warning: "Future assessments or reassessments may change the information found in the calculation of the RRSP deduction limit statement." If you've had a reassessment, use the newest statement, not the one in your drawer from last spring.

Reading the statement line by line

When Joanna looks closer, she'll find a line about unused contributions. The CRA says your unused RRSP, PRPP or SPP contributions are shown on the line "Unused RRSP contributions previously reported and available to deduct" on the statement (CRA, What to do with unused RRSP, PRPP or SPP contributions).

Why would anyone have unused contributions? Because the CRA lets you contribute now and deduct later. You can leave contributions in the plan and claim them in a future year, which some people do when they expect to be in a higher tax bracket later. Those amounts are reported on Schedule 7. The CRA's current page refers to Schedule 7 for contributions made from March 1, 2025 to March 2, 2026.

So if Joanna's statement shows a deduction limit of $20,000 and unused contributions of $5,000, she doesn't have $20,000 of fresh space. She has roughly $15,000 she can add before she starts eating into the overcontribution buffer. (Those are illustrative numbers, not hers or yours.)

What happens if you go over

The CRA describes an excess contribution as contributing more to your RRSP, PRPP or SPP than your RRSP deduction limit allows. There's a small cushion: generally, the tax applies to unused contributions that exceed your deduction limit by more than $2,000, and you only qualify for that extra $2,000 if you were 18 or older during the relevant year (CRA, Excess contributions).

The cost is real. The CRA says you generally pay a tax of 1% per month on the amount above that buffer. It also notes that withdrawals under the Home Buyers' Plan or Lifelong Learning Plan don't get you out of the 1% tax. If you think you might owe it, the CRA walks you through how to tell whether you need to file a T1-OVP return (CRA, Determine if you have to complete a T1-OVP). One of the situations where you may avoid the tax on some of the excess is withdrawing it before the end of the month the excess contribution was made, so acting quickly matters.

The $2,000 cushion is meant as a margin for error. It isn't extra room to plan around, and it doesn't come with a deduction.

A few practical habits

• Check the statement every year. Your limit changes with your income, pension adjustment and contributions.
• Track contributions made early in the year. Money you put in during the first part of the year can count toward the previous tax year, which is easy to lose track of if you contribute through more than one bank or a workplace group plan.
• Remember group plans. Payroll contributions to a group RRSP use your room too.
• Look at the whole picture. Your TFSA and FHSA have their own separate room and rules, so RRSP room is only one piece of deciding where your next dollar goes.

What this doesn't tell you

The rules above are clear, but applying them to your situation isn't always simple:

• Your statement can be out of date. It reflects what the CRA knew when it assessed you. Contributions you've made since then, or a reassessment, can change the real picture.
• Pension adjustments vary a lot. Two people with the same salary can have very different room depending on their workplace pension. Your T4 and plan administrator are the authority on your PA.
• Deducting isn't always the right move right away. Whether to claim a contribution now or carry it forward depends on your income this year versus later, and that's a personal call.
• Spousal RRSPs, HBP repayments and other situations add their own rules that this article doesn't cover.
• Rules and limits change. The figures here come from CRA pages as read in October 2026. Always check the current CRA page before acting.
