OAS Taxation, GIS, and What Happens to Payments When You Leave Canada or Pass Away

The Old Age Security (OAS) program offers guaranteed income for seniors, but there are important rules about how OAS is taxed, how it interacts with other supports like the Guaranteed Income Supplement (GIS), and what happens if you leave Canada or pass away.

Understanding these aspects ensures you’re making informed decisions about your OAS benefits throughout retirement.

How OAS Payments Are Taxed

OAS payments are considered taxable income:

They are added to your total taxable income for the year.
Taxes are withheld based on your estimated income, but final tax owed is reconciled when you file your tax return.
OAS is taxed at your marginal tax rate, alongside other income sources like CPP, pensions, and investment income.

Unlike RRSP withdrawals, OAS does not benefit from tax-deferral strategies. However, effective income planning can help minimize the tax impact.

At Optimize, we build OAS taxation into your comprehensive retirement cash flow plan to ensure tax efficiency.

The Guaranteed Income Supplement (GIS): Extra Support for Low-Income Seniors

For lower-income retirees, the Guaranteed Income Supplement (GIS) provides additional monthly income:

Feature of GIS	Explanation
Eligibility	Available to OAS recipients with limited additional income.
Income-tested	Payments based on annual household income.
Tax treatment	GIS benefits are non-taxable.
Reduction with income	Payments gradually reduced as income rises, similar to OAS clawback.

As income increases, GIS payments are gradually reduced, similar to the OAS clawback. Optimize helps you navigate GIS eligibility and coordinates it within your broader income strategy.

Receiving OAS Benefits While Living Outside Canada

If you move outside Canada, your OAS eligibility depends on:

Your prior Canadian residency history.
Typically, you must have lived in Canada for at least 20 years after age 18 to continue receiving OAS abroad.
For those with less than 20 years of residency, benefits may stop after six months outside Canada unless covered by international social security agreements.

Note: Payments are adjusted to reflect your non-resident tax obligations. Optimize assists with planning for OAS continuation if you’re considering living abroad.

What Happens to OAS Payments Upon Death

OAS payments stop immediately upon the beneficiary’s death. Unlike CPP, there are:

No survivor benefits or death benefits specifically associated with OAS.
Payments made after death must be repaid to the government.

It is the responsibility of the estate or surviving family to notify Service Canada to ensure payments are halted promptly.

Optimize supports your family with clear guidance on OAS cessation and estate-related considerations.
