Introduction
Every year, thousands of Ontario retirees pay more income tax than necessary—not because they made a mistake, but because the rules quietly changed.
Imagine sitting down with your spouse to compare last year's tax return with this year's. Your retirement income hasn't changed very much. Your investments are similar. Yet somehow your tax bill is lower, and your Old Age Security (OAS) payments have increased.
How did that happen?
Many retirees never notice because they simply hand their tax slips to an accountant and sign wherever they're told. Unfortunately, tax rules don't stay the same.
Some changes quietly save you money.
Others quietly cost you money.
In this article, you'll learn five important retirement tax changes that every Ontario retired couple should understand in 2026, including:
A federal tax cut that automatically lowers your taxes
Two valuable tax credits many retirees overlook
Two income thresholds that can quietly reduce your retirement benefits
Why your TFSA has become one of the most powerful retirement planning tools available
Let's begin.
The Federal Tax Rate Has Dropped
One of the biggest tax changes is also one of the easiest to miss.
The lowest federal income tax rate has been reduced from 15% to 14%.
While one percentage point doesn't sound significant, it affects every dollar earned within the first federal tax bracket.
For retirees earning approximately $50,000 of taxable income, this can translate into roughly $500 of annual federal tax savings.
For retired couples, that savings can potentially double.
Over a retirement lasting 20 to 30 years, those annual savings can easily add up to many thousands of dollars.
The Basic Personal Amount Has Also Increased
Along with the lower tax rate, Canadians also benefit from a larger Basic Personal Amount.
In 2026, each eligible Canadian can earn $16,452 before paying federal income tax.
For married couples, that's nearly $33,000 of household income protected from federal tax.
Although these savings happen automatically, understanding them helps explain why your tax return may look different from previous years.
The Age Amount Tax Credit Is Worth More Than Ever
Once you turn 65, you become eligible for the federal Age Amount tax credit.
For 2026, the maximum federal Age Amount is approximately $9,208.
Combined with provincial credits, this can reduce taxes by approximately $1,800 to $2,000 per person, depending on where you live.
For couples over age 65, both spouses may qualify.
That means the household could save between $3,500 and $4,000 annually.
However, there is an important catch.
Beware of the Age Amount Phase-Out
Many retirees don't realize the Age Amount is income-tested.
Once your individual net income exceeds approximately $46,432, the credit begins to shrink.
Notice the word individual.
This is one of the biggest differences between tax planning for singles and tax planning for couples.
Consider this example.
Suppose one spouse withdraws a large amount from their RRIF while the other withdraws very little.
Although the household income stays the same, one spouse could lose a significant portion of their Age Amount credit simply because their income isn't evenly distributed.
Smart retirement tax planning isn't only about how much you withdraw.
It's also about whose account the money comes from.
The OAS Clawback Still Matters
Old Age Security remains one of Canada's most valuable retirement benefits.
However, once your individual income exceeds approximately $95,323, your OAS begins to be clawed back.
Every dollar above that threshold reduces your benefit.
Many couples assume they don't need to worry because their combined income isn't exceptionally high.
The problem is that OAS is measured per person, not per household.
A couple earning $96,000 together may receive their full OAS.
A surviving spouse earning that same amount alone could lose a significant portion of their benefits.
The Survivor's Tax Trap
One of the least discussed retirement planning issues occurs after the death of a spouse.
When one spouse passes away:
Pension splitting may disappear.
RRIF income becomes concentrated on one tax return.
OAS clawback becomes more likely.
Higher tax brackets may apply.
Planning for this situation years in advance can significantly reduce future taxes.
The Capital Gains Inclusion Rate Stayed at 50%
Over the past two years, many Canadians worried about proposed changes to capital gains taxation.
Some retirees even sold cottages or investment properties earlier than planned because they feared higher taxes.
That proposal has now been abandoned.
The capital gains inclusion rate remains 50%.
For retirees, this means investment decisions can once again be made based on financial goals rather than tax uncertainty.
If you own appreciated assets, you now have more flexibility to plan when—and how—you sell them.
Why the TFSA Is More Valuable Than Ever
If there is one retirement planning strategy that ties all these tax changes together, it's maximizing your Tax-Free Savings Account (TFSA).
Unlike RRIF withdrawals:
TFSA withdrawals are tax-free.
They don't count toward OAS clawback.
They don't reduce the Age Amount.
They don't increase taxable retirement income.
For couples, this creates enormous planning opportunities.
Instead of funding retirement entirely through RRIF withdrawals, many retirees can combine RRIF and TFSA withdrawals to keep both spouses below important tax thresholds.
That strategy may preserve thousands of dollars in tax credits and government benefits over retirement.
Five Action Steps for Ontario Retirees
If you're retired—or planning to retire soon—consider taking these five steps this year:
Review Your Tax Returns Together
Compare both spouses' tax returns side by side to identify differences and opportunities.
Monitor Your Age Amount
Watch whether either spouse's income is approaching the Age Amount phase-out threshold.
Watch Your OAS Income
Avoid unnecessary RRIF withdrawals that could trigger an OAS clawback.
Plan Large Capital Gains Carefully
Now that the inclusion rate remains at 50%, plan property or investment sales strategically rather than reacting to rumours.
Maximize Your TFSA
Whenever appropriate, use TFSA withdrawals to reduce taxable income and preserve valuable tax credits.
Frequently Asked Questions
Do these tax changes affect only Ontario retirees?
The federal tax changes apply across Canada. However, provincial tax credits and retirement planning strategies may differ by province.
Does the OAS clawback use household income?
No. OAS clawback is based on each individual's net income, not household income.
Is the Age Amount based on combined income?
No. The Age Amount is calculated separately for each spouse.
Why is the TFSA so valuable in retirement?
Because TFSA withdrawals are tax-free and don't count toward income-tested benefits such as the Age Amount or OAS clawback.
Final Thoughts
The biggest retirement tax savings often don't come from finding a secret investment or chasing higher returns.
They come from understanding how Canada's tax rules work—and making informed withdrawal decisions each year.
For retired couples, small adjustments to RRIF withdrawals, TFSA usage, pension income splitting, and tax planning can preserve thousands of dollars over a long retirement.
Rather than waiting until tax season, review your retirement income strategy annually. A proactive plan can help reduce taxes, protect government benefits, and provide greater confidence throughout retirement.
