Co-Buying + FHSA + HBP Stacking 2026: How Two Buyers Combine Every Program.
Two buyers, one home: how co-buyers stack FHSA rooms, HBP withdrawals, and the home buyers tax credit on a single 2026 purchase without double-counting.
Stacking is where co-buying pays double: the programs attach to buyers, not to the property. Pillars: Co-Buying a Home in Canada and the FHSA Guide Canada 2026.
Stacking order that works
- Max FHSA first — deductible contributions, tax-free qualifying withdrawals, no repayment. Deadline logic: FHSA 2026 Deadlines.
- Layer HBP withdrawals — tax-free now, repaid over 15 years. Compare: FHSA vs HBP.
- Paper the split — whose FHSA funded which share of the down payment goes in the co-ownership agreement: Co-Buying Agreement Checklist.
Traps
- A buyer who owned (and lived in) a home in the last four years generally fails first-time-buyer tests — verify both buyers before counting both rooms.
- HBP repayments start on a fixed clock; FHSA has none. Budget the repayment alongside the new mortgage — see Income Needed for a $400,000 Mortgage.
- Keep program funds traceable to each buyer for lender down-payment sourcing.
