TFSA vs RRSP: Which Is Better?

The Core Difference

Both accounts shelter investments from tax while they grow — but the tax treatment is reversed. RRSP: Contributions are tax-deductible (you get money back now), growth compounds tax-deferred, and withdrawals are taxed as ordinary income. TFSA: Contributions come from after-tax dollars (no deduction), growth is completely tax-free, and withdrawals are never taxed — under any circumstances.

The question is not which account is 'better.' It is: at what marginal tax rate are you contributing, and at what marginal tax rate will you withdraw? If your current rate is higher than your expected retirement rate, RRSP wins. If they're equal or your retirement rate is higher, TFSA wins.

2026 Contribution Limits

TFSA: The 2026 annual contribution limit is $7,000. If you have never contributed and were 18 or older in 2009, your total cumulative TFSA room as of January 1, 2026 is $102,000. Unused room carries forward indefinitely. Withdrawals restore contribution room the following January 1 — you can re-contribute in a future year without penalty.

RRSP: The 2026 contribution limit is 18% of your prior year earned income, to a maximum of approximately $32,490 (the 2025 limit; the 2026 limit is announced in November). Unused RRSP room also carries forward indefinitely. The RRSP contribution deadline for the current tax year is March 1 of the following year.

A Concrete Tax Comparison

Assume you earn $100,000 and face a 43.41% marginal rate (Ontario). You contribute $10,000. Into RRSP: you save $4,341 in tax this year, but owe tax on withdrawal. If you withdraw at $60,000 income in retirement (29.65% marginal rate), the net savings is $4,341 − $2,965 = $1,376 per $10,000 contributed.

Into TFSA: no tax refund now, but withdrawals are 100% tax-free regardless of your income. RRSP wins in this scenario because your current rate (43%) exceeds your retirement rate (29%). Now flip it: if you earn $50,000 (marginal rate ~29%) and retire on $55,000 income (marginal rate ~31%), the TFSA wins because your retirement rate exceeds your contribution rate.

When to Prioritize RRSP

RRSP is superior when: your current marginal rate is 30% or higher and you expect it to be lower in retirement; you are in your peak earning years (40s–50s) and expect a significant income drop at retirement; you have a defined benefit pension and want the RRSP deduction to offset high working income; you plan to use the Home Buyers' Plan (HBP) or Lifelong Learning Plan (LLP); or you want to use spousal RRSP contributions to equalize retirement income between spouses. The RRSP is also the right vehicle for income from employment, self-employment, or rental properties where your marginal rate in working years is meaningfully higher than retirement.

When to Prioritize TFSA

TFSA is superior when: your income is below $50,000 (the RRSP deduction is worth less in a low bracket); you are retired or semi-retired and want flexible, tax-free income; your income in retirement will be similar to your working income (common for business owners with corporate distributions, or those with large DB pensions); you are at risk of OAS clawback — TFSA withdrawals do not count toward the $90,997 clawback threshold; you qualify or might qualify for GIS — TFSA withdrawals do not count as income for GIS eligibility; you want to leave a tax-free estate — TFSAs can pass to a spouse as a successor holder with no tax consequences.

Impact on OAS Clawback and GIS

This is where the TFSA has a decisive advantage in retirement. RRIF withdrawals (mandatory from former RRSPs after age 71) count as taxable income and can trigger or worsen OAS clawback. At income above $90,997, you lose 15% of OAS for every dollar over the threshold. A retiree with $110,000 of RRIF income loses approximately $2,850/year in OAS.

Replacing that RRIF income with equivalent TFSA withdrawals — by having built the TFSA instead of the RRSP — preserves full OAS. Similarly, every dollar of TFSA withdrawal preserves GIS eligibility for low-income retirees, whereas RRSP/RRIF withdrawals reduce GIS by 50 cents per dollar. This makes TFSA the single best account for low-income Canadians regardless of age.

The Optimal Strategy for Most Canadians

For most middle-income Canadians earning $60,000–$130,000, the best approach is to use both accounts strategically: During peak earning years, maximize RRSP first (the deduction at 33%+ rates is too valuable to pass up), then contribute remaining savings to TFSA. In early retirement (before CPP/OAS begins), draw RRSP/RRIF income in amounts that keep you in low tax brackets — this is the RRSP meltdown strategy. Direct the after-tax proceeds to TFSA.

From age 65–70, use TFSA income to supplement CPP and OAS without triggering clawback. After 70, preserve the TFSA as long as possible — it grows tax-free and passes to your estate without tax when left to a spouse.

Spousal RRSP: A Third Tool for Couples

Couples have an additional option: the Spousal RRSP. The higher-income spouse contributes to an RRSP registered in the lower-income spouse's name, claiming the deduction themselves. When the lower-income spouse withdraws in retirement (after a 3-year attribution period), the withdrawal is taxed at their lower rate.

This achieves income splitting before retirement — particularly useful for couples where one partner has a large DB pension and the other has minimal retirement income. Combined with pension income splitting at 65, a spousal RRSP can save a couple thousands of dollars annually.

Withdrawal Rules Compared

RRSP: Withdrawals at any time are subject to withholding tax (10% under $5,000; 20% on $5,000–$15,000; 30% above $15,000 in most provinces) and full income tax at year-end. RRSP must be converted to a RRIF by December 31 of the year you turn 71. RRIF minimum withdrawals are mandatory starting the following year, escalating with age (roughly 5.28% at 72 rising to 20% at 95+). TFSA: No withholding tax, no mandatory withdrawals, no deadlines.

Withdrawals at any time, for any reason, with no tax consequence. Contribution room is restored the following January 1. No RRIF conversion ever required.
