RRSP season, the first weeks of the year before the contribution deadline, is when many Canadian side hustlers decide what to do with last year’s earnings. Start by setting aside what you owe: side hustle income is taxed at your marginal rate, and self-employed people pay both shares of CPP, 11.9% on pensionable earnings above the $3,500 basic exemption in 2026. With the remainder, an RRSP contribution can lower your taxable income, and your net self-employment earnings count as earned income, which builds RRSP room for the next year at 18% of earned income up to the annual limit ($33,810 for 2026, $35,390 for 2027). A TFSA or, for first-time buyers, an FHSA may fit better depending on your income. This guide explains the rules, not which account or product to choose.

How does side hustle income affect your RRSP room?
Net self-employment income counts toward earned income, which sets next year’s RRSP room. The CRA’s T4040 guide says earned income adds employment earnings, self-employment earnings, and certain other income, then subtracts specific employment expenses and business or rental losses. Your RRSP deduction limit is generally 18% of the previous year’s earned income, up to the annual dollar limit, adjusted for pension adjustments and plus unused room carried forward. Your notice of assessment shows your exact limit.
| Limit | 2026 | 2027 | Source |
|---|---|---|---|
| RRSP dollar limit | $33,810 | $35,390 | CRA limits |
| TFSA dollar limit | $7,000 | Not yet listed | CRA limits |
| CPP earnings ceiling (YMPE) | $74,600 | Not yet listed | CRA limits |
| FHSA first-year room | $8,000 | Not listed | FHSA |
When is the RRSP deadline for the 2026 tax year?
Contributions made in the first 60 days of 2027 can generally be deducted on your 2026 return. For the 2025 tax year, the CRA counted contributions made from March 4, 2025 to March 2, 2026 (RRSP deduction limit). By the same 60-day count, the window for 2026 would end March 1, 2027; confirm the date on the CRA’s page before relying on it. Contributions that exceed your deduction limit by more than $2,000 are generally taxed at 1% per month.
What should a side hustler do with money before contributing?
Cover what you owe first, then decide between accounts. In order:
- Set aside income tax and CPP on your net side hustle income; see how much tax to set aside.
- Check instalments. If your net tax owing is more than $3,000 ($1,800 in Quebec) in the current year and either of the two previous years, you may have to pay quarterly instalments on March 15, June 15, September 15, and December 15. See CRA tax instalments for side hustlers for the calculation options.
- Pay any balance by April 30, 2027. Self-employed people can file by June 15, but the CRA’s filing rules make the balance due April 30.
- Then compare an RRSP, TFSA, or FHSA for any extra money.
How do the RRSP, TFSA, and FHSA compare for side hustle money?
All three shelter investment growth, but they treat contributions and withdrawals differently.
| Account | Contribution deductible? | Room built by | Notes |
|---|---|---|---|
| RRSP | Yes | 18% of prior-year earned income, up to the limit | Withdrawals are generally taxable |
| TFSA | No | Annual dollar limit ($7,000 for 2026) | Check your room in your CRA account (TFSA) |
| FHSA | Yes | $8,000 in the first year you open it | For first-time home buyers; transfers from an RRSP are not deductible |
Illustrative example
Assume $10,000 in net side hustle income in 2026, no other earned income changes, and a 30% combined marginal tax rate. The income and rate are assumptions; real rates depend on your province and total income.
- RRSP room created for 2027 from this income: 18% × $10,000 = $1,800.
- Effect of a $2,000 RRSP contribution on 2026 tax, if you have the room: 30% × $2,000 = $600 less tax.
- CPP on the side hustle, if your employment income already covers the $3,500 exemption: 11.9% × $10,000 = $1,190, which an RRSP deduction does not reduce.
What RRSP-season mistakes do side hustlers make?
The common mistakes are contributing tax money and assuming room without checking.
- Contributing money owed to the CRA. Pay tax and CPP first.
- Guessing your limit. Use your notice of assessment or CRA account.
- Over-contributing. Amounts more than $2,000 over your limit are taxed at 1% a month.
- Forgetting CPP. RRSP deductions lower income tax, not self-employed CPP contributions.
- Missing the window. Contribute within the first 60 days of 2027 to count for 2026.
Which tax rules apply when you file in 2027?
Report side hustle income on Form T2125 and claim RRSP deductions on your return. Tax software such as Wealthsimple Tax TODO-AFFILIATE or TurboTax Canada TODO-AFFILIATE handles both, or you can use a professional. See tax on reselling and gig apps for platform slips and record keeping for receipts.

What are the common questions?
Does side hustle income create RRSP room?
Generally yes. The CRA's T4040 guide counts self-employment earnings in earned income, and RRSP room is generally 18% of the previous year's earned income up to the annual limit, adjusted for pension adjustments.
What is the RRSP limit for 2026?
The CRA lists the RRSP dollar limit as $33,810 for 2026 and $35,390 for 2027. Your personal limit depends on your earned income and carried-forward room and is shown on your notice of assessment.
When is the RRSP deadline for 2026 contributions?
Contributions made in the first 60 days of 2027 can generally count for 2026. For 2025, the CRA counted contributions up to March 2, 2026. Confirm the 2027 date on the CRA's page.
Should I put side hustle money in an RRSP or TFSA?
It depends on your income, plans, and room. RRSP contributions are deductible and withdrawals are generally taxable; TFSA contributions are not deductible. Set aside tax and CPP first. This is not financial advice.
Does an RRSP contribution reduce CPP on self-employment income?
No. RRSP deductions reduce taxable income, but self-employed CPP contributions are based on net business income. Self-employed people pay 11.9% on pensionable earnings above the $3,500 exemption in 2026.
