United States: dealer versus investor status
The IRS doesn't look at holding period alone — it weighs a pattern of conduct: frequency of flips, intent at purchase, and whether flipping is a primary business activity. If a taxpayer is classified as a "dealer," flipped properties are treated as inventory, not capital assets, under IRC §1221(a)(1).
| Dealer | Investor | |
|---|---|---|
| Tax treatment | Ordinary income (10–37%) | Capital gain (short or long-term) |
| Self-employment tax | 15.3% on net earnings | None |
| 1031 exchange | Not available | Available (investment property) |
| Held under 12 months | Ordinary income either way | Short-term capital gain (still ordinary rates) |
| Held over 12 months | Still ordinary income (dealer status overrides) | Long-term capital gain (0/15/20%) |
The practical takeaway: dealer status is expensive specifically because of the added self-employment tax layer on top of ordinary income rates — and holding a flip longer doesn't fix this the way it would for a genuine investment property, since dealer classification overrides the holding-period benefit entirely.
Canada: the Residential Property Flipping Rule
Effective for dispositions on or after January 1, 2023, Canada's federal Residential Property Flipping Rule works differently — it's a bright-line test, not a multi-factor judgment call. Any residential property (including rental property) held for fewer than 365 consecutive days before sale is automatically deemed to produce fully taxable business income, regardless of the seller's stated intent.
- No access to the 50% capital gains inclusion rate — the full gain is taxable.
- No principal residence exemption, even if the seller lived in the property.
- The CRA does not need to prove flipping intent — the rule applies automatically based purely on the holding period.
- Limited exceptions exist for specific qualifying life events (death, disability, job relocation, divorce, and similar circumstances).
This matters directly for how a flip should be modelled: a typical flip's holding period (often well under a year) means most Canadian flips fall squarely inside this rule by default, not as an edge case.
Why this matters for your numbers, not just your tax return
Neither of these tax treatments is reflected in a flip's headline profit or ROI number — both are pre-tax figures. A deal that looks strong on paper can look meaningfully different after roughly 37%+ combined US dealer tax, or after Canada's full business-income treatment with no exemptions. Building an estimate of after-tax proceeds into a deal review, rather than treating pre-tax profit as the final answer, is worth doing before relying on a projected return.
This is general information based on current published rules as of 2026, not tax advice specific to your situation — both the US dealer/investor classification and Canada's exceptions involve fact-specific tests. Confirm your own treatment with a qualified accountant before making a decision based on this.
