We fight your property assessment.
Put in your Calgary address. We compare your assessment against similar properties in your community using the City's own published data, show you exactly what we found, and tell you whether it is worth fighting. If it is not, we say so and charge you nothing.
What we actually do
Screen it
We pull your parcel from the City's assessment roll and compare it against properties of the same type and era in your community. You see the comparables, the gap, and every error we found in your record.
Talk to the assessor
During the customer review period we take it up with the City directly. A correction agreed here needs no hearing and no board.
File the complaint
We file with the Assessment Review Board before the deadline as a backstop, and run a written or virtual hearing if it comes to that. You do not attend.
What we will not tell you
We will not quote you a success rate. We have not run a Calgary cycle yet, and a performance claim you cannot substantiate is both dishonest and against the law. When we have our own results we will publish them.
We will not promise a number. Every saving on this site is an estimate with a range, built from published data, and it says which data and how old.
We will not hide the downside. The Assessment Review Board can lower your assessment, leave it alone, or raise it. That is on the record before you decide anything.
The numbers behind all of this
| Figure | Value | Source |
|---|---|---|
| Calgary combined residential tax rate, 2026 | 0.0066499 | City of Calgary, effective 2026-03-31 |
| Board filing fee, residential | $50 | Calgary Assessment Review Board, checked 2026-09-13. Paid by you to the board, not to us |
| Board filing fee before January 31 | $40 | AR 201/2017, Schedule 1 Section 6, and s.12(2) for the withdrawal case. This supersedes an earlier reading that treated the refund as City practice only. |
| 2026 complaint deadline | 2026-03-23 | Read the date off your own notice, it governs |
If the board decides in your favour, or if the assessor corrects every issue under complaint and the complaint is withdrawn before the hearing, the filing fee is refunded to you.
TaxFight launches for the 2027 Calgary assessment cycle. The 2027 dates are not published yet. The 2026 dates above are shown as the pattern, and the date on your own notice is the one that governs.
