RRSP $33,810 Limit: The 18% Formula, Explained

$33,810 is the headline RRSP number for 2026 — but most people do not get that much new room. Your new room is 18% of last year's earned income, capped at $33,810. Here is the exact income where the cap kicks in, and the worked math below it.

How we check the numbers: every figure on this page is calculated from official CRA, Statistics Canada or Bank of Canada data and cross-checked with the free calculators on this site — run them yourself to verify.

The short version

2026 RRSP dollar limit$33,810

Formula18% of earned income

Income to hit the cap$187,834

2025 dollar limit$32,490

The rule is simple: new RRSP room = the smaller of 18% of your previous year's earned income and the year's dollar limit. For 2026, that means 18% of your 2025 earned income, capped at $33,810. The CRA prints your exact total deduction limit — including any unused room carried forward — on your Notice of Assessment and in CRA My Account.

The $187,834 threshold, step by step

Divide the cap by the rate: $33,810 ÷ 0.18 = $187,833.33. So $187,834 of 2025 earned income is the first whole-dollar income that fully reaches the cap. The rounding matters by six cents: at $187,833, 18% is $33,809.94, not quite $33,810. Many tables round the threshold to $187,833; the exact division is $187,833.33.

Above that income, extra earnings create no extra new room — the dollar cap binds. Below it, every extra dollar of earned income adds 18 cents of new room.

Worked examples: new room at each income

$50,000 earned income$9,000 new room

$100,000 earned income$18,000 new room

$150,000 earned income$27,000 new room

$187,834 earned income$33,810 new room

$50,000 × 18% = $9,000. Well under the cap, so the 18% figure is your new room.
$80,000 × 18% = $14,400. Still the 18% figure.
$100,000 × 18% = $18,000. Just over half the cap.
$150,000 × 18% = $27,000. Still $6,810 short of the cap.
$250,000 × 18% = $45,000, capped at $33,810. The cap cuts $11,190 off the 18% figure.

These are new room only, before two adjustments: minus any pension adjustment, plus any unused room carried forward from earlier years. Unused room never expires.

What counts as earned income — and what does not

Counts: employment income, net self-employment income, net rental income, and certain other items such as taxable support received.

Does not count: investment income — interest, dividends, capital gains — pension income, and government benefits. A year lived entirely on investment income creates no new RRSP room, no matter how large the portfolio.

This is the most common surprise in the formula: it is 18% of earned income, not 18% of total income.

Two things that change your personal limit

Pension adjustment (PA). If you belong to a workplace pension plan or DPSP, the value of the benefit you earned — shown in box 52 of your T4 — is subtracted from your new room. A generous defined benefit pension can use up most or all of it, even at a high salary.
Unused room carried forward. Room you never used stacks on top of each year's new room, with no expiry. That is why your personal deduction limit on your Notice of Assessment can be far above $33,810, even though $33,810 caps only one year's new room.
Spousal RRSPs share your room. Contributions to your spouse's RRSP use your deduction limit, so your own and spousal contributions combined cannot exceed it.

Over-contributing: the $2,000 buffer and the 1% penalty

The CRA allows a $2,000 lifetime over-contribution buffer with no penalty. Any excess above that buffer is taxed at 1% per month for each month it stays in the plan, until you withdraw it or gain new room. Check your Notice of Assessment figure before contributing near the limit — the CRA's number does not yet include contributions it has not been told about.

For the 2026 tax year, contributions made in the first 60 days of 2027 — up to March 1, 2027 — can still be deducted on your 2026 return.

How the limit has moved

2025: $32,490 — income to hit the cap: $180,500.
2026: $33,810 — income to hit the cap: $187,834 (up $1,320, or 4.06%, from 2025).
2027: $35,390 already confirmed — income to hit the cap: $196,611.

The 2027 figure is already known because each year's RRSP dollar limit equals the previous year's money purchase limit. If your 2026 earned income is near the threshold, expect roughly $35,390 of new room for 2027 only if your 2026 earned income reaches about $196,611.

Frequently asked questions

What is the RRSP limit for 2026?

Your new RRSP room for 2026 is 18% of your 2025 earned income, up to a dollar limit of $33,810. Your total deduction limit can be higher if you have unused room carried forward, or lower if a pension adjustment applies.

How much income do you need to get the full $33,810 of RRSP room?

$33,810 divided by 18% is $187,833.33, so $187,834 of 2025 earned income is the first whole-dollar income that fully reaches the cap. At $187,833, 18% is $33,809.94 — six cents short.

What counts as earned income for RRSP room?

Employment income, net self-employment income and net rental income count, among other items. Investment income such as interest, dividends and capital gains, pension income and government benefits do not create RRSP room.

Does a workplace pension reduce my RRSP room?

Yes. Your pension adjustment — the value of the pension benefit you earned in a workplace plan, shown in box 52 of your T4 — is subtracted from your new RRSP room. A generous defined benefit pension can use up most or all of it.

What happens if I contribute more than my RRSP limit?

The CRA allows a $2,000 lifetime over-contribution buffer with no penalty. Any excess above that buffer is taxed at 1% per month for each month it stays in the plan until you withdraw it or gain new room.
