Manitoba Property Tax Credit When Buying or Selling a House

The Credit Follows the Principal Residence

The Homeowners Affordability Tax Credit applies to an eligible principal residence. When you sell one home and buy another within the same tax year, the tax bill advance and any eligible claim depend on the annual bill, your residence, and closing adjustments. The process is not automatic, and the timing matters.

What Happens on the Selling Side

The annual property tax bill for the home you're selling was issued earlier in the year with the HATC advance already applied. At closing, your lawyer handles a standard statement of adjustments that prorates taxes between buyer and seller based on the closing date. The municipality does not retroactively claw back the HATC advance from you — it stays on the bill, and the proration adjusts only the net taxes.

The bill may already show the HATC advance. Check the closing statement to see how the taxes were prorated, and confirm with the municipality whether any current-year declaration or claim is needed.

What Happens on the Buying Side

Here is where problems start. If you buy a property mid-year, the municipality may have already issued the original tax bill to the previous owner. A later added or supplementary bill will not include the HATC advance.

Municipalities do not apply the HATC advance retroactively on supplementary or added bills. If an eligible credit was not applied, claim it through Form MB479 using the instructions for that tax year.

The Self-Declaration Step

Many municipalities — Winnipeg in particular — require a self-declaration that the property is your principal residence before they apply the HATC advance to future bills. If you bought in 2026 but don't file the self-declaration until late in the year, your 2027 bill may still arrive without the credit.

In Winnipeg, you can submit the declaration through the city's online portal or contact 311. Rural municipalities set their own processes, so check whether your municipality accepts an online, mailed, or in-person declaration. Do this as soon as you take possession — don't wait for the next bill cycle.

Claiming Both Properties in One Year

You can only claim the HATC on one principal residence at a time. If you owned two properties simultaneously during the year (closing on the new home before the old one sold), the credit goes to whichever property was your principal residence. You can't split it across two properties.

If you sold in March and bought in April, the closing statement shows how the annual taxes were prorated. Ask the municipality which residence's school taxes qualify for a current-year HATC claim, and use the matching MB479 instructions for any eligible amount not shown as an advance.

What to Do Right Now

1. File the self-declaration with your new municipality immediately after closing.
2. Keep your old property's tax statement — you need it for the tax return.
3. Keep any added or supplementary bill — it will not show the HATC advance; use the matching MB479 instructions for any eligible credit claim.
4. File MB479 in the spring, entering school taxes paid on your principal residence.
