The T1032 Pension Splitting Trap: How Seniors Accidentally Reduce Their Own GIS

Pension splitting using the T1032 election is a popular tax strategy for Canadian couples — it can reduce your household tax bill by shifting income from a higher-earning spouse to a lower-earning one. But for couples where one spouse receives GIS, pension splitting can be a financial trap that costs far more than it saves. Every year, Canadian couples accidentally reduce or eliminate their GIS by filing T1032 without understanding the downstream consequences.

How Does Pension Splitting Work?

Pension splitting allows one spouse to transfer up to 50% of eligible pension income to their partner on their tax return. Eligible income includes workplace pensions, RRSP annuities, and certain other pension payments. CPP, OAS, and GIS are not eligible for splitting.

The result is that the higher-earning spouse reports less income, and the lower-earning spouse reports more. In many cases, this reduces overall household tax because the income moves from a higher tax bracket to a lower one.

Pension splitting is purely a tax-reporting mechanism. The actual money doesn’t move between bank accounts — only the income attribution changes on paper. But that paper change has real consequences for GIS, which is calculated based on individual reported income.

Why T1032 Reduces the Lower-Income Spouse’s GIS

GIS is income-tested based on your individual net income — not your household income. When you split pension income to the lower-earning spouse, their reported individual income increases. If that increase pushes them above the GIS threshold, their monthly payment drops or disappears entirely.

In practice: A couple in Ottawa uses 50% pension splitting to save $600/year in income tax. They don’t realize that the split eliminates the lower-income spouse’s GIS entitlement of $875/month. The annual GIS loss: $10,500. The net result: they saved $600 on taxes and lost $10,500 in benefits. A $9,900 mistake.

How to Know If T1032 Is Hurting Your GIS

1. Find last year’s T1 return and look for a completed T1032 form (Pension Income Splitting Election)
2. Note the amount of pension income transferred to each spouse
3. Add the transferred pension income to the receiving spouse’s total income
4. Compare that total to the GIS income threshold for their situation (~$21,624 for single; combined thresholds for couples)
5. If the combined income exceeds the threshold after the split, GIS is being reduced or eliminated
6. Calculate the GIS loss using the reduction rate ($1 lost per $2 of income above zero for single recipients)

Should You Always Avoid Pension Splitting?

Not necessarily — the answer depends on both spouses’ incomes relative to the GIS threshold. If the lower-income spouse’s income after splitting still falls below the threshold, GIS isn’t affected and splitting may still save taxes.

The truth is: pension splitting is only beneficial when the tax savings exceed the GIS reduction. In most cases involving a low-income spouse on GIS, the GIS loss far outweighs the tax savings. Run the numbers before filing T1032 every year.

A tax professional who understands GIS can model both scenarios — with and without splitting — to show you which outcome is financially better. Don’t rely on software defaults, which optimize for tax minimization without accounting for GIS impacts.

What If You’ve Already Filed T1032 This Year?

1. Check whether your return has been assessed by CRA (log in to CRA My Account)
2. If the return has NOT yet been assessed, contact CRA at 1-800-959-8281 and ask about amending your return to remove the T1032 election — this may be possible before assessment
3. If already assessed, you’ll need to file a T1-ADJ (Adjustment Request) to change the election — this requires supporting documentation and can take several months
4. Going forward, omit T1032 from next year’s return and recalculate GIS impact before filing

Service Canada’s July GIS reassessment uses the income figures on your final assessed return. If you successfully amend your T1032 election before July, the corrected income figures will be used for your GIS calculation. Speed matters.

Frequently Asked Questions

Can I split CPP income with my spouse?
CPP credit splitting (not the same as pension income splitting) is a separate process managed by Service Canada. It applies to CPP contributions made during a marriage or common-law partnership. Unlike T1032 pension splitting, CPP credit splitting is a permanent administrative action, not an annual election. It can also affect GIS — contact Service Canada before requesting CPP credit splitting.

What if my spouse doesn’t receive GIS — does T1032 still affect anything?
If neither spouse receives GIS and neither is close to the threshold, T1032 is generally safe from a benefits perspective. The concern applies specifically when one spouse receives or is close to qualifying for GIS. Always model the GIS impact before filing the election.

Does T1032 affect the Allowance for a spouse aged 60–64?
The Allowance is income-tested for the GIS-receiving spouse’s income level, not the Allowance recipient’s. However, pension splitting can indirectly affect Allowance eligibility if it changes the combined income used for threshold calculations. Seek specific advice for your situation.

Is there a way to split income without using T1032?
Some alternative strategies include pension income from income-splitting-eligible accounts like RRSPs that are converted to joint spousal RRIFs, or contributions to a spousal RRSP. These are longer-term planning tools, not quick annual elections. A financial advisor can help evaluate which approach minimizes taxes while protecting GIS.

What if we’ve been splitting pensions for 10 years?
Check whether the lower-income spouse has received reduced GIS during those years as a result. If you suspect the splitting has been reducing GIS, consider whether the tax savings have actually offset the GIS reductions over time. Going forward, you can simply choose not to use T1032 — the election is optional each year.

Does omitting T1032 this year fix the GIS problem for July 2026?
Yes — if you don’t use T1032 on your 2025 tax return (filed by April 30, 2026), the lower-income spouse’s income will reflect only their actual income, not any transferred amount. This should restore their GIS entitlement at the July 2026 reassessment, assuming their actual income remains below the threshold.

Model Before You File — Every Year

Pension splitting is optional. It’s a choice made on each year’s return. That means you have the chance every year to assess whether it’s helping or hurting your household’s overall financial position.

Before filing T1032, run two scenarios: one with splitting, one without. Add up the tax saving and the GIS impact. Choose the option that puts more money in your household account — not just less on your tax bill.
