Your Alberta property assessment, explained

In Alberta, your municipality assesses every property each year and mails you a notice. Your property tax bill is based on that assessed value. If your home is assessed higher than similar homes nearby, you can ask for a review and, if needed, file a complaint.

You may be fairly assessed. If you are, we'll tell you.

The check is free and you don't need an account to see your result.

The one date that matters: 60 days from your notice

Your complaint deadline is 60 days after the notice of assessment date printed on your notice. That is the date on the notice itself, not the day it arrived in your mailbox. If day 60 falls on a Saturday, Sunday or holiday, the deadline moves to the next business day.

Source: Municipal Government Act, RSA 2000, c. M-26 (consolidated to May 14, 2026), s. 284(4) ('complaint deadline' = 60 days after the notice of assessment date set under s. 308.1 or 324(2)(a.1)); s. 309(1)(b)-(c); s. 461(1)(b), (1.1) (late complaint invalid); roll: Interpretation Act, RSA 2000, c. I-8, s. 22(1)-(2)

Two things to know:

• Your notice prints the deadline. If the date on your notice differs from what you worked out, use the date on your notice, and call us if you're unsure.
• Late complaints don't count. The Municipal Government Act makes a complaint filed after the deadline invalid. There is no grace period.

Step one: ask the assessor to look again

Calgary and Edmonton each offer a review period after notices go out. During that time you can talk to an assessor, point out an error or share comparable homes, and ask for a correction without a formal complaint.

This is how we work in every Alberta file. We ask the assessor to review your assessment first, and we file a formal complaint only to protect your rights if the review isn't resolved 7 business days before the deadline. In practice we aim to file at least 5 business days before your complaint window closes.

Step two, if needed: a complaint to the assessment review board

If the review doesn't settle it, a complaint goes to your municipality's assessment review board. It is an independent panel that hears the owner (or their agent) and the assessor, and then decides the value. Which panel hears your complaint depends on the type of property. Your municipality will tell you.

A complaint must include the municipality's filing fee. When you work with us, we pay the complaint fee when we file. What happens to that fee if the complaint succeeds is set out in your engagement letter.

If your file goes to a hearing, a person represents you. Software never appears in front of a board.

Calgary, Edmonton and the rest of Alberta

• Calgary and Edmonton: both cities publish their assessment rolls as open data, so we can compare your home with similar homes and show you the result right away. See our Calgary and Edmonton pages.
• Other Alberta municipalities: the same 60-day rule applies. Most don't publish their rolls, so we'll ask you to send your notice, and a person will check it by hand for free.

What we look for

We compare your assessment per square foot with similar homes in your community, built around the same time and of a similar size. We also look for errors in the facts on file, such as the wrong living area, a basement recorded as finished when it isn't, or the wrong garage type. Our methodology page explains exactly how we choose comparable homes.

If a review could plausibly raise your assessment, we tell you and don't recommend filing.

You can do this yourself

You don't need us: you can contact your assessor or file a complaint yourself. Your notice explains how. If you'd rather have someone handle it, see how it works and what it costs.

Every year is a new year

Alberta assesses every year, so a reduction this year doesn't carry forward automatically. Every year is a new decision: we show you the new number and fee, and nothing is filed or charged unless you approve it.
