Without these, we calculate only tax credits and rebates (~$8,444 + Bill C-4). With them, you see the full stack.

Choose 0 if you don't have an FHSA yet. The 5-year clock starts at account opening (not first contribution).

HBP allows withdrawing up to $60,000 per person. Funds must be in your RRSP for at least 90 days.

What's next?

The calculation above provides the financial picture. Here are the two key items to know before the next step.

The Quebec credit ($5,875) in brief

This is a REFUNDABLE credit — Revenu Québec pays the difference even when no tax is owed. The credit may be claimed from October 2026 onwards without waiting for the tax return if the eligible amount exceeds $1,000.

Bill C-4 (up to $50,000) for new construction

For new construction with an agreement signed after March 20, 2025, the GST rebate can reach 100% on the first $1,000,000. The builder often applies it at source at signing.

Year-by-year action plan

Stacking $75,000 or more is the result of a sequence of decisions taken before signing. Here is the methodology applied in pre-approval.

Today — even if the purchase is 4 to 5 years away

  • Open the FHSA. Contribute a symbolic $100 if needed — the 5-year window begins at account opening, not at first contribution.
  • Verify your eligibility under the 5-year rule, accounting for any prior joint ownership with a former spouse.
  • If you already hold an RRSP, note the balance to plan your HBP.
Anthony King's tip: the FHSA account must be 5 years old at the withdrawal date to unlock the full $40,000. A client lost $8,000 of annual rights by opening her FHSA 3 months before signing rather than 3 years before.

Year 1 before purchase

  • Maximize the FHSA: $8,000 per person.
  • Contribute to the RRSP — funds must be deposited 90 days before any HBP withdrawal.
  • Obtain mortgage pre-approval through your broker.

Year 2 — new construction vs resale decision

  • Year 2 FHSA contribution.
  • Reinvest the Year 1 FHSA tax refund into the RRSP for the HBP.
  • Decide: Bill C-4 pays up to $50,000 in GST on eligible new construction, and zero on resale.
Anthony King's tip: if a 12 to 18-month delivery is feasible, Bill C-4-eligible new construction becomes mathematically difficult to beat. A new $400,000 condo generates $20,000 of GST — fully recovered by Bill C-4. On a $750,000 new build, that's $37,500 recovered.

Year 3 — purchase year

  • Final FHSA contribution.
  • Confirm Bill C-4 eligibility with the builder if the property is new construction.
  • Active property search with stack calculations per target address.
Anthony King's tip: explicitly ask the builder whether the Bill C-4 rebate is applied AT SOURCE (net payment at signing) or must be claimed via CRA after occupancy (8 to 16-week delay). This affects your closing liquidity need by $20,000 to $50,000.

Month of signing

  • Coordinate FHSA and HBP withdrawals with the notary calendar.
  • Keep every document: purchase agreement, construction contract, GCR certification, welcome tax invoice, notarial deed.
  • If parents co-sign on title, verify the impact on your first-time buyer status (case-by-case analysis).

After signing

  • Pay the welcome tax to the municipality within 30 days of invoicing (typically 90 days after the deed).
  • If the eligible credit exceeds $1,000, request the advance payment from October 2026 onwards (saves 12 to 18 months of waiting compared to claiming at the tax return).
  • Claim the non-refundable credits (Quebec $1,400 + federal HBTC $1,169) at your next tax return.
Anthony King's tip: do not settle the welcome tax with a line of credit while awaiting the advance credit. The advance credit arrives within weeks, but the tax is due within 30 days. Use an emergency fund or a short non-HBP RRSP advance instead. A $1,200 line of credit balance adds approximately $60 per month in unnecessary interest.
Why a calculator doesn't replace the full file

This calculator applies the official formulas mechanically. It does not substitute for pre-approval for four concrete reasons:

  • Real eligibility depends on edge cases: spouse having been an owner within 5 years, construction with agreement straddling March 20, 2025, multi-generational co-signing on title.
  • Best rates are not displayed to retail clients — comparison across 14 lenders typically represents a 0.50% to 1.00% gap from posted rates.
  • FHSA and HBP withdrawal timing must align with the notary calendar and builder delivery (minimum 90 days in RRSP for HBP). A sequencing error blocks the withdrawals.
  • Certain major renovations may be treated as new construction for Bill C-4 purposes — an interpretive rule to validate with a tax specialist before the offer.

At Anthony King — Architectes Hypothécaires, this stacking calculation has been integrated into every first-time buyer pre-approval since April 2026. You receive a precise estimate based on your target municipality, a complete cash-flow timeline (including the October 2026 advance payment where applicable), a new construction vs resale comparison, and notary and builder coordination. Free consultation, no commitment.

Calculator assumptions
  • The calculator assumes all buyers are 18 years or older (required for FHSA and Bill C-4). If a buyer is younger or a parent co-signs on title, validate with your broker — co-signing may affect first-time buyer status.
  • The 5-year rule is presumed satisfied: neither you nor your spouse occupied a home owned by either of you during the year of acquisition or any of the four preceding calendar years. The rule includes joint ownership with a former spouse.
  • The welcome tax is computed on standard provincial brackets, without Montreal municipal surtax. For Montreal purchases above $500,000, the actual tax is higher — however the Quebec credit remains capped at $5,875 regardless of the total.
  • The provincial QST rebate for new construction is not included in this calculation — it applies separately under its own thresholds. Your broker can integrate this calculation into the full context of your file.
