RRSP vs TFSA in Retirement — The Best Withdrawal Strategy

You have spent decades building your RRSP and TFSA. Now you are retiring and the question shifts: which account do you draw from first?

It seems like a simple question. It is not. The order in which you draw down your accounts has a significant impact on your lifetime tax bill — potentially worth tens of thousands of dollars. Most Canadians get this wrong, either by defaulting to the RRSP first or by drawing randomly without a plan.

Understanding What Each Account Does in Retirement

Before discussing strategy, it helps to be clear on what each account actually does when you start withdrawing.

Account	Tax on Withdrawal	Impact on Benefits	Growth Inside
RRSP / RRIF	Fully taxable as income	Counts toward OAS clawback threshold	Tax-deferred
TFSA	Zero tax	Does not affect OAS or GIS	Tax-free
Non-registered	Capital gains / dividend tax	Counts toward income-tested benefits	Taxable annually

The OAS Clawback Problem

Old Age Security (OAS) begins clawing back at a net income threshold of approximately $93,000 in 2026. For every dollar of income above that threshold, you repay 15 cents of OAS. At around $150,000 of income, your OAS is fully clawed back.

If your RRIF mandatory withdrawals, CPP, OAS, and other income push you above $93,000, you are losing OAS you already earned. This is one of the most painful — and most avoidable — tax hits in retirement.

The solution: strategically draw down your RRSP before CPP and OAS begin, when your income is lower. This reduces the RRIF balance that will generate mandatory withdrawals later, and keeps your income below the clawback threshold.

The Withdrawal Sequence That Works

There is no single universal answer — your situation depends on your income sources, account sizes, and tax bracket. But for most Alberta professionals who retire with significant RRSPs and TFSAs, this sequence works well:

Phase 1: Early Retirement (Age 60–65)

If you retire before CPP and OAS begin, your taxable income is at its lowest point. This is the ideal time to draw from your RRSP — you are filling up low tax brackets deliberately. Use TFSA withdrawals sparingly here. The goal is to reduce the RRSP balance while the tax cost is lowest.

Phase 2: CPP and OAS Begin (Age 65–71)

Now CPP and OAS are flowing in. Your taxable income rises. Switch to drawing more from your TFSA and non-registered accounts, which have more favourable tax treatment. Continue modest RRSP/RRIF withdrawals to avoid bracket creep at 71.

Phase 3: Mandatory RRIF Withdrawals (Age 71+)

At 71, your RRSP converts to a RRIF and mandatory minimums begin. If you have done the earlier planning right, your RRIF balance is manageable and the forced withdrawals do not push you above the OAS clawback threshold. Use TFSA to supplement income as needed — it is completely tax-free and does not affect OAS.

Why the TFSA Is So Valuable Late in Retirement

The TFSA is often described as a short-term savings tool. In retirement, it is actually most powerful as a late-stage income supplement and estate planning vehicle.

• Withdrawals are not counted as income — they do not trigger OAS clawbacks or affect income-tested benefits like GIS
• Room is restored the following calendar year, so you can re-contribute if your situation changes
• On death, the TFSA passes to a spouse as a successor holder with no tax consequences
• It is the most flexible account you have — no mandatory withdrawals, ever

Couples: The Spousal Dimension

Retirement income splitting opens additional planning opportunities for couples. CPP can be split between spouses. Pension income from a RRIF can be split after age 65. Drawing from the higher-income spouse’s RRSP first while the lower-income spouse draws from their TFSA can equalize incomes and reduce the household tax bill significantly.

For couples where one spouse has significantly more RRSP savings than the other, spousal RRSP contributions during the working years (if any remain) can smooth out this imbalance before retirement.

Non-Registered Accounts: Where They Fit

If you have non-registered investments — a taxable brokerage account — the general rule is to hold them longer than your RRSP when possible. Capital gains are taxed at a lower rate than RRSP income, and eligible dividends receive the dividend tax credit. Drawing from non-registered accounts before depleting the RRSP can make sense in higher-income years when you want to avoid additional RRIF withdrawals.

The exception: if your non-registered account holds investments with large accrued capital gains, selling triggers tax immediately. Plan dispositions carefully.

The Right Answer for Alberta Professionals

Alberta has no provincial sales tax and no provincial supplemental pension. High-earning years in energy, engineering, or business often mean large RRSP balances accumulated during peak income. This combination — large RRSPs, no provincial safety net, high prior-year contributions — makes withdrawal sequencing especially important here.

The professionals I work with who do this well share one characteristic: they started the planning early. Not at 71 when the RRIF conversion forces their hand — but at 58 or 60, when they still had a decade to reshape their income landscape.

If you are in that window, the conversation is worth having now.
