Taxes, OAS, GIS & CPP — What Actually Happens

This is the most important page on this website for retirees living on fixed income. If you receive the Guaranteed Income Supplement (GIS), are near the OAS clawback threshold, or are worried about a large reverse mortgage deposit being treated as taxable income — read this carefully.

The short version: reverse mortgage proceeds are a loan. Under Canadian tax law, a loan is not income. It is not taxable. It does not affect your government benefits. Full stop.

Now let us explain exactly why, with specifics for each government program.

The Fundamental Principle: A Loan Is Not Income

When you take a reverse mortgage, the lender gives you money and registers a lien (mortgage) against your property. You owe this money back. Under Canadian tax law — specifically the Income Tax Act — borrowed money is not income. It does not matter how much you borrow, how you receive it, or what you do with it.

This is the same principle that applies to all other loans. When you take out a car loan, that money is not income. When you use a credit card, the available balance is not income. When you draw on a HELOC, those funds are not income. A reverse mortgage is no different.

Reverse mortgage proceeds:

• Are not reported on your T1 General tax return
• Do not appear on any T-slip (T4, T5, T4A, etc.)
• Are not included in your "net income" calculation (Line 23600)
• Are not included in your "total income" calculation (Line 15000)
• Are not subject to withholding tax

The lender does not issue you a tax slip for the funds you receive. The CRA is not notified that you received the money as income. There is no reporting mechanism because there is nothing to report — it is a debt obligation, not earnings.

OAS (Old Age Security) — No Clawback

Old Age Security is a monthly payment available to Canadians aged 65 and older. The amount depends on how long you have lived in Canada. As of 2025-2026, the maximum OAS payment is approximately $727 per month (ages 65-74) or $800 per month (ages 75+).

The OAS clawback — officially called the "OAS recovery tax" — kicks in when your net income exceeds $90,997 (2025-2026 threshold). For every dollar of net income above this threshold, 15 cents of OAS is clawed back. If your net income exceeds approximately $148,000, your OAS is eliminated entirely.

Here is why a reverse mortgage does not trigger the clawback: the clawback is based on net income (Line 23600 of your tax return), and reverse mortgage proceeds are not income.

Worked Example: OAS

Margaret, age 72, has the following annual income:

• CPP: $14,400
• OAS: $8,724
• Private pension: $22,000
• RRIF minimum withdrawal: $8,000
• Total net income: $53,124

Margaret receives a $175,000 lump sum from a reverse mortgage. Her net income for the year remains $53,124 — unchanged. The $175,000 does not appear on her tax return. She is well below the $90,997 clawback threshold. Her OAS payment is completely unaffected.

Now compare: if Margaret had withdrawn $175,000 from her RRSP instead, her net income would have jumped to $228,124 — well above the OAS elimination threshold. She would lose her entire OAS for the year and owe significant income tax on the withdrawal. The reverse mortgage avoids both consequences entirely.

GIS (Guaranteed Income Supplement) — Fully Protected

The Guaranteed Income Supplement is a monthly benefit for low-income seniors who receive OAS. It is the most income-sensitive benefit in the Canadian retirement system — GIS is reduced by 50 cents for every dollar of income above the threshold, and it disappears entirely at relatively modest income levels.

For a single senior in 2025-2026, GIS is eliminated when annual income (excluding OAS) exceeds approximately $21,624. For a couple where both receive OAS, the combined income threshold is approximately $28,560.

GIS is calculated based on your income — not your assets, not your bank balance, not the value of your home. This distinction is critical.

Worked Example: GIS

Robert, age 69, is a single senior with the following annual income:

• CPP: $9,600
• OAS: $8,724
• GIS: $7,200 (based on his income level)
• No pension, no RRSP, no other income
• Total income (for GIS calculation, excluding OAS): $9,600

Robert takes a $150,000 lump sum from a reverse mortgage. The next day, his bank account shows $150,000 more than it did yesterday. Does his GIS change? No.

His income for GIS purposes remains $9,600 (his CPP). The $150,000 reverse mortgage proceeds are not income. They are not reported anywhere. GIS is not an asset-tested benefit — the fact that Robert now has $150,000 in his bank account does not matter. Only his income matters, and his income has not changed.

Robert continues to receive his full GIS payment of $7,200 per year. If he had instead withdrawn $150,000 from an RRSP, his income would have jumped to $159,600, his GIS would be eliminated entirely, and he would owe approximately $45,000 in income tax. The reverse mortgage avoids all of this.

CPP (Canada Pension Plan) — No Effect Whatsoever

CPP payments are based on your contribution history during your working years (ages 18 to 65 or 70). Your CPP amount was determined by how much you earned and contributed over your career. Nothing you do in retirement changes it.

A reverse mortgage has zero effect on your CPP payment. Your CPP will be the same amount whether you take a $50,000 reverse mortgage, a $500,000 reverse mortgage, or no reverse mortgage at all.

What About the Provincial Benefits?

Several provinces offer additional income-tested benefits for seniors:

• Ontario: Ontario Trillium Benefit, Ontario Senior Homeowners' Property Tax Grant — based on income, not affected by reverse mortgage proceeds
• British Columbia: BC Senior's Supplement — income-tested, not affected by reverse mortgage proceeds
• Alberta: Alberta Seniors Benefit — income-tested, not affected by reverse mortgage proceeds
• Quebec: Solidarity Tax Credit senior component — income-tested, not affected

The principle is universal: any benefit that is calculated based on income is unaffected by reverse mortgage proceeds, because reverse mortgage proceeds are not income.

Can I Invest the Proceeds?

Yes — but where you invest matters for tax and benefit purposes.

TFSA (Tax-Free Savings Account)

You can deposit reverse mortgage proceeds into your TFSA, up to your available contribution room. Investment income earned inside a TFSA is completely tax-free and is not counted as income for OAS, GIS, or any other income-tested benefit. This makes a TFSA the ideal vehicle for reverse mortgage proceeds that you want to invest.

RRSP (Registered Retirement Savings Plan)

You cannot contribute reverse mortgage proceeds to an RRSP, because RRSP contributions require "earned income" (employment income, self-employment income, or rental income). Reverse mortgage proceeds are a loan, not earned income, so they do not create RRSP contribution room and cannot be contributed.

If you are under 71 and still have unused RRSP room from prior years, you can use that room — but the reverse mortgage itself does not generate new room.

Non-Registered Investments

You can invest reverse mortgage proceeds in a non-registered (taxable) investment account. However, any income earned (interest, dividends, capital gains) will be taxable and will count toward your net income for OAS and GIS purposes. This could affect your benefits.

For example: if Robert (from our GIS example above) invests $150,000 in a non-registered account earning 4% interest, he would earn $6,000 per year in interest income. That $6,000 would be added to his net income and would reduce his GIS. The reverse mortgage itself did not affect GIS, but the investment income from the proceeds did.

Strategy tip: If you are a GIS recipient, deposit reverse mortgage proceeds in a TFSA (up to your room) or a high-interest savings account within a TFSA. Any investment income earned inside the TFSA is invisible to the GIS calculation.

Will a Large Deposit Trigger a CRA Audit?

This is a common fear, and the answer is no. A large bank deposit from a reverse mortgage will not trigger a CRA audit.

The CRA monitors income — specifically, it compares the income you report on your tax return against the T-slips issued by your employers, banks, and investment companies. A reverse mortgage lender does not issue a T-slip. There is nothing for the CRA to compare against or flag.

Financial institutions are required to report certain transactions to FINTRAC (the Financial Transactions and Reports Analysis Centre of Canada) for anti-money-laundering purposes — specifically, cash transactions over $10,000 or suspicious transactions. A reverse mortgage disbursement is an electronic transfer from a regulated lender to your bank account. It is a documented, legitimate loan. It is not a cash transaction and it is not suspicious.

Your bank may ask about a large incoming deposit as part of their standard procedures. "It's a reverse mortgage disbursement from [lender name]" is the complete answer. There is nothing unusual or concerning about it.

What About the Interest? Is It Tax-Deductible?

Under Canadian tax law, interest on borrowed money is deductible only if the borrowed funds are used for the purpose of earning income from a business or property. This means:

• If you use reverse mortgage proceeds for personal expenses (living costs, home renovations, travel, paying off debt), the interest is not tax-deductible.
• If you use the proceeds to invest in income-producing assets (stocks, bonds, rental property), the interest may be deductible. Consult your accountant for specifics.

Most reverse mortgage borrowers use the funds for personal purposes, so the interest is not deductible. However, for borrowers who invest the proceeds, there may be a tax advantage to claiming the interest as a deduction. This is an area where professional tax advice is worth the cost.

Summary: The Tax and Benefits Picture

The Bottom Line for Retirees on Fixed Income

If you are a Canadian retiree receiving OAS, GIS, or CPP, a reverse mortgage is one of the few ways to access a large sum of money without any tax consequences or benefit reductions. No other source of funds — not RRSP withdrawals, not pension commutations, not investment sales — can offer the same combination of tax-free proceeds and zero impact on income-tested benefits.

For GIS recipients in particular, this is profound. GIS is the most aggressively clawed-back benefit in the Canadian system, and it serves the lowest-income seniors. A reverse mortgage lets these individuals access $50,000, $100,000, or even $200,000 without losing a single dollar of GIS. No other financial product can do this.
