OAS Deferral Calculator: Quebec Couple With $390K in Non-Registered GICs, QPP at 65, and the $95,323 Clawback Threshold in 2026

The Setup: A Laval Couple, Both 65, With Four Income Streams Each

A Laval couple, both turning 65 in 2026, are deciding whether to start OAS immediately or defer. Both retired from professional careers with defined-benefit pensions. Their combined income picture:

Each spouse also holds $200,000 in RRSPs that haven't been converted to RRIFs yet. That conversion isn't mandatory until the year they turn 71. The RRSPs are the strategic asset in this deferral decision — more on that below.

What Happens If Both Take OAS at 65

The maximum monthly OAS for a 65–74-year-old in 2026 is $742.31, or $8,908/year. Adding this to each spouse's $93,875 of existing income:

Each spouse loses $1,119/year to the OAS recovery tax — about 12.6% of their gross OAS. Combined, the couple forfeits $2,238/year in clawback. They're receiving $742.31/month on paper, but netting about $649/month each after the recovery tax.

OAS at 65, 67, and 70: Net-of-Clawback Comparison Table

OAS increases by 0.6% per month of deferral past 65 — that's 7.2% per year, to a maximum 36% enhancement at age 70. Here's how the three start ages compare for each spouse, accounting for clawback at every stage:

The Clawback Mechanics: How the $95,323 Threshold Works

Under section 180.2 of the Income Tax Act, the OAS recovery tax is 15% of every dollar of net income above $95,323. It's calculated on your individual T1 return — not combined household income. Each spouse's clawback is independent.

OAS is fully eliminated when net income reaches approximately $155,000 for recipients aged 65–74. This couple is nowhere near full clawback — their issue is the partial clawback zone, where every additional dollar of income (including OAS itself) triggers a 15-cent recovery.

A common misconception: OAS income counts toward the clawback calculation. Your gross OAS is included in line 11300 of your T1, which flows into net income on line 23600. So the OAS you receive can itself push you further into clawback territory — a self-reinforcing effect that makes the recovery tax slightly larger than a simple “15% of income over $95,323” would suggest.

Quebec's 16.5% Federal Abatement: What It Does and Doesn't Affect

Quebec residents receive a 16.5% abatement on basic federal tax — this compensates for Quebec collecting its own provincial income tax rather than piggybacking on the federal system. The abatement means Quebec retirees typically pay less federal income tax on pension income, including OAS.

In practice, this means the effective tax rate on OAS income is slightly lower for Quebec residents (because the federal portion is reduced by 16.5%), but the clawback calculation is identical. For planning purposes, the deferral decision is driven almost entirely by the clawback math and life expectancy — the abatement is a rounding error in the analysis.

The Breakeven Calculation: When Does Deferring to 70 Pay Off?

Each spouse who defers from 65 to 70 forgoes five years of net OAS payments. Here's the cumulative math, broken into the three phases that matter:

Phase 1: Ages 65–69 (Deferring Spouse Receives $0)

Phase 2: Ages 70–74 (Enhanced OAS Begins, Before Age-75 Bump)

Phase 3: Ages 75+ (10% OAS Increase Kicks In)

At 75, all OAS recipients get a permanent 10% increase (effective since July 2022). This compounds on the deferral enhancement:

The remaining $25,320 deficit at age 75, divided by the $2,999 annual advantage, is 8.4 years. Add that to age 75: breakeven at approximately age 83–84.

The RRSP Meltdown Window: Why Deferral Opens a Tax Planning Door

Here's where the deferral strategy connects to the rest of the retirement plan. Each spouse holds $200,000 in RRSPs that must be converted to a RRIF by December 31 of the year they turn 71. Once inside a RRIF, mandatory minimum withdrawals begin — 5.28% at age 71, rising to 6.82% at 80 and 11.92% at 90. Those mandatory withdrawals are fully taxable and count toward OAS clawback.

If both spouses take OAS at 65, they have almost no room to do RRSP withdrawals without deepening their clawback. Their pre-OAS income is $93,875, and adding OAS pushes them to $102,783. Every additional dollar of RRSP withdrawal adds 15 cents of OAS recovery tax on top of the marginal income tax.

If they defer OAS to 70, the picture changes. From 65 to 69, their net income is $93,875 — $1,448 below the clawback threshold. They're not receiving OAS, so there's nothing to claw back. They can withdraw up to $1,448 of RRSP per year with zero clawback consequence. And even above that amount, the only cost is income tax on the RRSP withdrawal — no OAS recovery tax stacking on top.

This is the piece that no OAS deferral calculator captures in isolation. The deferral isn't just about the 36% OAS enhancement — it's about the five-year window where you can reorganize your registered assets without the clawback penalty. For a Quebec couple holding $400,000 of combined RRSPs, the RRIF-reduction benefit can be worth as much as the deferral enhancement itself.

When Deferral Is the Wrong Call

The breakeven at 83–84 assumes both spouses live into their mid-80s. The deferral math breaks down in specific situations:

• Health flag: A terminal diagnosis or strong family history of death before 80 makes the five-year opportunity cost too large. Take OAS at 65 and invest the difference.
• Cash-flow need: If the couple needs every dollar of income to cover expenses between 65 and 70 (unlikely at $93,875/year each, but possible with major medical costs or family obligations), deferral creates a real gap.
• One spouse with much lower income: If Spouse B earned significantly less and has pre-OAS income below $95,323 even with full OAS, that spouse should take OAS at 65 (no clawback) while the higher-income spouse defers. Staggering also hedges against one spouse dying before breakeven.
• GIS eligibility: Not relevant here (this couple is far above GIS thresholds), but for lower-income retirees, OAS deferral can interact with the Guaranteed Income Supplement in unexpected ways.

QPP vs. CPP: Does the Pension Source Change the OAS Analysis?

No. The Québec Pension Plan and Canada Pension Plan are coordinated programs with identical benefit structures and contribution rates. QPP income is reported on your T1 return the same way CPP income is — it's fully taxable and fully counted in the net income calculation that determines OAS clawback.

The one Quebec-specific wrinkle: QPP is administered by Retraite Québec, not Service Canada. If this couple defers OAS, they request the deferral through Service Canada (federal), not through their QPP administrator. The two systems don't automatically coordinate timing — you can start QPP at 65 and defer OAS to 70 (or vice versa) independently. For a deeper dive on how QPP fits into the deferral decision, see our Quebec retiree OAS deferral guide.

The Bottom Line for This Laval Couple

Both spouses should defer OAS to 70. The 36% enhancement, the clawback-reduction benefit, and the RRSP meltdown window all point the same direction. The breakeven is age 83–84, and both are statistically favoured to live past it. Between 65 and 70, they should aggressively draw down their RRSPs into TFSAs, shrinking their future RRIF obligations and keeping income below the clawback line once the enhanced OAS starts flowing.

The combined benefit of deferral plus RRSP meltdown, compared to taking OAS at 65 and leaving the RRSPs alone until mandatory RRIF conversion at 71, is in the range of $40,000–$60,000 per spouse over a 20-year retirement — driven by the enhanced OAS payments, the avoided clawback, and the tax-free TFSA growth on the converted funds.
