Tax Planning for Retirees: Brackets, OAS, Splitting

Tax planning in retirement is a different exercise from tax planning while you work. During your career the question is usually how to defer and deduct. In retirement it becomes how to draw income in the most tax-efficient order and rhythm, year after year, so your lifetime tax bill is as low and as smooth as possible. The retirees who do this well are rarely chasing the lowest tax in a single year; they are managing their taxable income deliberately across decades.

This guide is for retired and soon-to-retire Canadians in Ottawa and across Canada, particularly couples and those with meaningful registered balances. It is general information, not advice for your situation; confirm the specifics with your accountant.

Think in terms of your taxable income each year

The organising idea of retirement tax planning is control over your taxable income. Unlike a salary, much of your retirement income is within your control: how much you withdraw from an RRSP or RRIF, when you realise gains in a non-registered account, when you start CPP and OAS, and how much you draw tax-free from a TFSA. Each of these is a lever on your taxable income, and therefore on your marginal rate.

Because rates rise with income, the aim is to avoid spiking into high brackets in some years while leaving low brackets unused in others. Smoothing income across years often reduces the total tax paid over a retirement, even if it means paying a little more in the early years. Understanding your marginal vs. average tax rate is the foundation for every decision that follows.

Split pension income with your spouse

For couples, pension income splitting is one of the most valuable tools available. It lets you allocate up to half of eligible pension income to a lower-income spouse on your tax returns, equalising taxable income between you. That equalisation lowers combined tax, can preserve credits, and reduces exposure to the OAS clawback. It is a simple annual election, not a transfer of money. Our dedicated guide, pension income splitting, covers which income qualifies and how age affects it.

Watch the OAS clawback

Old Age Security is subject to a recovery tax, commonly called the clawback, once your individual net income passes an annual threshold. In the income zone above that threshold, each extra dollar of income not only attracts regular tax but also reduces your OAS, which effectively raises your marginal rate. Retirees manage this by:

• splitting pension income to keep each spouse’s income below the threshold,
• drawing from a TFSA, which does not count as income, to top up cash flow without raising net income, and
• smoothing withdrawals so income does not spike above the threshold in a single year.

The threshold is set annually, so plan against the current year’s figure. Our note on the OAS clawback explained covers the mechanics in detail.

Plan the order you draw your accounts

The sequence in which you draw from your accounts has a surprisingly large effect on lifetime tax. The three broad buckets behave differently:

• Registered (RRSP/RRIF): fully taxable on withdrawal, with mandatory RRIF minimums from the year after conversion.
• Non-registered: only the gains are taxed, at the capital gains inclusion rate, and you control timing.
• TFSA: entirely tax-free and does not count as income.

A common approach is to draw taxable registered income up to the top of a lower bracket each year, then use TFSA withdrawals to meet any remaining need without raising taxable income. This keeps you out of higher brackets and away from the clawback. The right order is personal, and our guide to retirement withdrawal order in Canada explores the trade-offs.

By the end of the year you turn 71, your RRSP must become a RRIF or an annuity, and the RRIF carries a mandatory minimum withdrawal each year, rising with age. These minimums are taxable income whether you need the cash or not. A large RRSP left untouched until 71 can force high, fully taxable withdrawals later, sometimes pushing you into higher brackets or the clawback. This is why some retirees deliberately draw modest RRSP income in their sixties, in lower-income years, to reduce the balance before minimums begin. Our guides to RRSP to RRIF conversion and RRIF minimum withdrawal rules cover the details.

A simplified illustration

The table below is an illustrative, hypothetical example comparing two drawdown styles for the same retiree. Figures are rounded, use simplified assumptions, and are not a forecast; your result depends on your province, balances, and circumstances.

Approach	Early retirement (60s)	Later retirement (70s+)	Illustrative lifetime effect
Leave RRSP untouched, draw TFSA/non-registered	Low taxable income	Large forced RRIF minimums; higher brackets, clawback risk	Higher lifetime tax
Draw modest RRSP income early, smooth throughout	Moderate taxable income	Smaller RRIF minimums; steadier brackets	Lower lifetime tax

The numbers are illustrative, but the principle is dependable: smoothing registered withdrawals across the whole retirement usually beats deferring everything and facing large mandatory withdrawals later. The right amount to draw early depends on your bracket and your other income.

When you start CPP and OAS is itself a tax and income decision. Deferring CPP increases the eventual benefit by about 0.7% per month to age 70, and deferring OAS increases it by 0.6% per month, but the extra income also counts toward the clawback and your bracket. For some retirees, deferring government benefits while drawing down registered accounts in the interim lowers lifetime tax and increases guaranteed indexed income later. Our guide to when to start CPP weighs the considerations.

Managing non-registered gains and dividends

Retirees with a taxable account have additional levers. Because only 50% of a capital gain is included in income, and eligible Canadian dividends receive a tax credit, non-registered income can be relatively tax-efficient when managed well. The timing of realised gains is within your control: harvesting losses against gains, spreading a large disposition across two calendar years, and realising gains in lower-income years can all reduce the tax. Our note on tax-loss harvesting in Canada covers offsetting gains with losses, a technique that remains useful in retirement.

One caution specific to retirees is that the dividend gross-up can quietly raise net income and, with it, exposure to the OAS clawback. A portfolio heavy in eligible dividends can push a retiree closer to the clawback threshold even when the actual cash received is modest, because the grossed-up amount is what counts. This is a reason to look at the whole income picture rather than any single source, and it connects to the broader discipline of tax-efficient investing in Canada.

The TFSA deserves special mention, because it is the one account whose withdrawals do not count as income at all. That makes it uniquely useful late in retirement: it can fund a large one-time expense, a new vehicle or a home repair, without pushing you into a higher bracket or triggering the OAS clawback in that year. Retirees who kept contributing to their TFSA through their working years often find it the most flexible tool they have for managing taxable income in retirement. Where possible, preserving some TFSA capacity as a tax-free reserve, rather than spending it first, gives you room to smooth income in the years it matters most.

Bringing it together

Good retirement tax planning is a yearly discipline: split pension income, watch the clawback threshold, draw accounts in a sensible order, manage RRIF minimums, and coordinate benefit timing. None of these is dramatic alone, and all of them interact, which is why they belong in a single coordinated plan rather than handled piecemeal. Our tax planning and retirement planning services are designed to keep them working together across a long retirement.

Next step

The tax you pay in retirement is far more controllable than most people assume, and small adjustments each year compound into meaningful savings over decades.
