GIS: The Benefit Lower-Income Retirees Keep Leaving on the Table

The benefit too many modest savers overlook

Brigitte is 67, retired and living in Sudbury, Ontario, on what most people would call a tight budget. She worked hard her whole life in jobs that never came with a pension, set aside what she could, and ended up with a small RRSP, a TFSA she had nurtured carefully, and her Old Age Security. She had heard of something called the Guaranteed Income Supplement, but she assumed it was for people with nothing at all — certainly not for someone like her who had managed to save a little. That assumption was costing her real money every single month.

Brigitte's story is worth telling because she is far from alone. The Guaranteed Income Supplement is one of the most under-claimed and most misunderstood benefits available to lower-income Canadian retirees, and a surprising number of people who qualify either never apply or unknowingly arrange their income in a way that shrinks what they receive.

What the GIS actually is

Here is the public, well-established part. The Guaranteed Income Supplement is a monthly, non-taxable payment added on top of Old Age Security for lower-income seniors. To receive it you must already be receiving OAS, and — this is the crucial part — it is income-tested. The amount you get depends on your income, and as your income rises, your GIS is gradually reduced. Above a certain income level, it disappears entirely.

That single feature, the income test, is the whole ballgame. The GIS is not based on how much you have saved or what your assets are worth. It is based on your income for the year. And that distinction is exactly where most people go wrong, because not every dollar that funds your retirement counts as income in the eyes of this test.

"I always thought GIS was charity for people with nothing," Brigitte said. "Nobody told me it was about my income — or that I had any say over what counts."

Why the account you draw from matters so much

This is the insight that changed everything for Brigitte. Different accounts produce different kinds of income for tax and benefit purposes. Money you withdraw from an RRSP or a RRIF is fully taxable income — it lands squarely in the figure that the GIS income test looks at. A withdrawal from a Tax-Free Savings Account, on the other hand, is not taxable income at all, and so it does not show up in that figure.

Think about what that means for a retiree near the GIS threshold. If Brigitte pulls a thousand dollars out of her RRSP to cover an expense, that thousand dollars counts as income and can reduce her GIS for the year. If she pulls the same thousand dollars out of her TFSA instead, it funds the exact same expense — but to the income test, it is invisible. Same money in her pocket. Completely different effect on her benefit.

That is not a loophole or a trick. It is simply how these accounts are designed, and arranging your withdrawals sensibly around it is no different from any other piece of ordinary planning. The catch is that almost nobody explains it, so well-meaning retirees draw from whichever account feels natural and never realize they are trading away a benefit in the process.

Brigitte's situation

When Brigitte first sat down to look at her numbers, she had been doing what felt responsible: drawing what she needed from her RRSP first, and treating her TFSA as untouchable savings for emergencies. It is the same instinct a lot of careful people have. The trouble was that those RRSP withdrawals were lifting her taxable income just enough to claw back a meaningful slice of GIS she could otherwise have received.

She was, in effect, paying twice for that money — once in tax, and again in lost supplement. And because the lost GIS never appeared as a line on any statement, she had no idea it was happening.

What she did differently

Brigitte used TrackMoola's GIS estimator to see how her benefit responded as she changed where her retirement income came from. She did not change how much she needed to live on. She did not suddenly have more money. She simply reshaped which account funded her spending.

The comparison pointed clearly toward leaning more on her TFSA for the income that had been tipping her over, and drawing less from her RRSP in the years when staying under the threshold mattered most. TrackMoola did not lecture her on the mechanics or prescribe a formula; it let her see how much GIS she qualified for under each arrangement, side by side, and the better shape became obvious once she could see it.

Measure	Drawing mostly from RRSP	Leaning on TFSA instead
Taxable income for the year	Higher	Lower
GIS reduced by the income test	A large slice lost	Largely preserved
Monthly benefit (illustrative)	Baseline	About $220 more per month

For Brigitte's situation, reshaping which account she drew from translated into roughly an extra $220 a month of Guaranteed Income Supplement — a little over twenty-six hundred dollars a year of tax-free benefit she had been quietly leaving behind. On a budget as tight as hers, that was not a rounding error. It was the difference between watching every grocery receipt and breathing a little easier. These figures are illustrative; they describe Brigitte's circumstances and goals, not yours.

Why this is so easy to miss

The reason intelligent, careful people walk past this is that nothing about it feels like a mistake in the moment. Drawing from your RRSP to pay a bill is a perfectly ordinary thing to do. The cost does not show up as a penalty or a warning; it shows up as a smaller GIS payment that you have no easy way to connect back to the withdrawal that caused it. The damage is invisible, so the instinct never gets corrected.

There is also a psychological hurdle. Many lower-income retirees, like Brigitte, have spent years thinking of their TFSA as sacred — the account you never touch, the safety net of last resort. Being told that, in their case, the smarter move might be to spend the TFSA before the RRSP can feel backwards, almost reckless. It took seeing the benefit respond in front of her for Brigitte to trust that drawing on the TFSA was not throwing away her security but protecting a payment she relied on.

A note on what this is — and is not

It is worth being clear that none of this is about hiding income or gaming the system. Every dollar Brigitte withdrew was reported exactly as it should be. She simply chose, within the ordinary rules everyone plays by, which account to draw from. The GIS income test is part of how the benefit is designed, and arranging your withdrawals thoughtfully around it is no different from claiming a credit you are entitled to. Brigitte was not avoiding anything she owed — she was keeping a benefit she had every right to receive.

It is also worth saying that this is highly personal. The GIS interacts with your OAS, your other income, and your spouse's income if you have one. The thresholds shift each year. What worked for Brigitte will not be the right shape for everyone, which is exactly why seeing your own numbers matters more than any rule of thumb.

What her story illustrates

• The GIS is income-tested, not asset-tested. What you have saved matters far less than what shows up as income each year.
• Not all withdrawals count the same. RRSP and RRIF money is taxable income that can reduce GIS; TFSA withdrawals do not feed that figure at all.
• The account you draw from is a lever. Funding the same spending from a different account can preserve a benefit worth thousands a year.
• The cost is invisible. Lost GIS never appears on a statement, which is why so many people never realize they are giving it up.

Try it yourself

If your retirement income is modest and you are receiving — or expecting — Old Age Security, it is genuinely worth checking whether the Guaranteed Income Supplement could be part of your picture, and whether the way you draw your income is shrinking it. Put your own numbers into TrackMoola's GIS estimator and see how your benefit responds as you change which accounts fund your spending. Like Brigitte, you may discover there is real money on the table that you have every right to claim.
