The Math Has Changed – BC Property Tax Deferral Changes
Feb 26, 2026
Many homeowners use the BC Property Tax Deferment Program to delay paying their property taxes. In the past, this program worked like a low-interest loan from the province. Interest was relatively modest and was calculated using simple interest, meaning interest was charged only on the original amount deferred. For many people, this made deferring property taxes an affordable way to improve monthly cash flow or invest.
A common strategy for many of our clients was to defer their property taxes, invest those cashflows in their corporations, cash accounts or TFSAs and win the spread, which is the difference between your return on investment and the interest you pay on the borrowed funds. Going forward, from 2026 onward, the math has changed.
Starting with 2026 property taxes, deferred property taxes will now charge higher interest, and that interest will compound, meaning interest is charged on both the original amount and previously added interest. Over time, this can cause the balance to grow much faster than before.

Property Tax Deferment: Old Rules vs. New Rules
Example: $50,000 deferred for 10 years
(Illustration only – assumes a 5.0% prime rate)
| Old Rules (Before 2026) | New Rules (2026 and later) | |
| Interest type | Simple interest | Compound interest (monthly) |
| Interest rate used | Prime – 2% (≈ 3.0%) | Prime + 2% (≈ 7.0%) |
| How interest works | Interest only on original amount | Interest on balance and prior interest |
| Interest over 10 years | ~$15,000 | ~$50,000 |
| Total owing after 10 years | ~$65,000 | ~$100,000 |
Bottom line
Under the old rules, deferring $50,000 for 10 years added about $15,000 in interest. Under the new rules, that same deferral could add $50,000 in interest, mainly due to higher rates and compounding. If you are currently deferring, or planning to defer in the future, it’s important to understand that this program is now more expensive and should be reviewed carefully as part of your overall financial plan.
