City of Calgary Property Tax: Rates, Payment, and Late Penalties

City of Calgary property tax is calculated by multiplying your property’s assessed value by the applicable tax rate, and it’s due on the last business day of June each year. For 2026, the combined rate is 0.0066499 for residential property and 0.0221488 for non-residential property, covering both the municipal portion set by City Council and the education portion set by the Government of Alberta.¹ A home assessed at $500,000 would owe roughly $3,325 for the year.

How Your Bill Is Calculated

Two numbers drive your tax bill: your assessed value and the tax rate. The city assesses every Calgary property annually based on what it would likely have sold for on the open market as of July 1 of the previous year. Your 2026 assessment reflects market value on July 1, 2025, with the physical condition of the property captured as of December 31, 2025 to account for renovations, additions, or damage.²

Assessment notices are mailed at the beginning of January. Tax bills follow in May. Review the assessment when it arrives, because it’s the number your tax bill will be built on.³

2026 Property Tax Rates

Your bill has two components on a single invoice: the municipal portion, which funds services like police, fire, transit, parks, and road maintenance, and the provincial education portion, which is pooled provincially and distributed to school boards on a per-student basis.⁴ For 2026:¹

Residential: municipal rate 0.0038906 plus provincial rate 0.0027593, combined 0.0066499
Non-residential: municipal rate 0.0179986 plus provincial rate 0.0041502, combined 0.0221488

Multiply your assessed value by the total rate to get what you owe. Council sets the municipal rate through the annual budget; the provincial education rate is set in Edmonton and is outside the city’s control.

How and When to Pay

Property tax is due on the last business day of June. The exact date shifts with the calendar each year, so confirm it on your bill.³ Your nine-digit roll number, printed on both your assessment notice and tax bill, is the account identifier for every payment method.⁵

You have four ways to pay:

Tax Instalment Payment Plan (TIPP). Instead of one lump sum, equal monthly amounts are withdrawn from your bank account on the first of each month. There’s no charge to join, and once you’re enrolled you don’t need to re-apply each year.⁶
Online banking. Add the City of Calgary as a payee at your financial institution and enter your nine-digit roll number as the account number.
In person at your bank. Allow two to five business days for processing.
By mail. The city goes by the Canada Post postmark date, so a payment postmarked on or before the due date is on time. If the postmark is missing or unreadable, the city uses the date it receives the payment.⁷

The city does not accept credit card payments directly. Some third-party services in Canada offer credit card payment, but the city does not endorse them, and if a third-party payment reaches the city late, you’re still on the hook for the penalty.⁷

What Happens if You Pay Late

The city charges a 7% penalty on unpaid current-year taxes on July 1 and another 7% on October 1. If a balance remains after December 31, it becomes tax arrears and accrues an additional 1% penalty on the first of every month.⁸

On a $3,300 tax bill left completely unpaid, that works out to roughly $231 on July 1, another $231 on October 1, and about $33 per month starting in January. Paying part of the bill before the deadline lowers the base the penalty is calculated on. Enrolling in TIPP for the following year prevents the same crunch from repeating.

Prolonged non-payment goes further than penalties. When a property has tax arrears for more than a year, the city registers a tax recovery notification against the title, which shows up on any title search and can block a sale or refinance. If the arrears still aren’t cleared, the property can be sold at the city’s annual real estate public auction. The city must notify the owner and other interested parties and advertise the auction before that step. Paying the full arrears at any point before the auction removes the lien.⁹

If Your Assessment Looks Wrong

Your tax rate isn’t up for debate, but your assessed value is. If you believe the assessment doesn’t reflect what your property was worth on July 1, you have 67 days from the mailing of the notice in January to act. This is called the Customer Review Period.¹⁰

Start by contacting a city assessor to walk through how your property was valued and flag any factual errors, such as wrong square footage or a bathroom that doesn’t exist. Many disputes end there. If you can’t reach agreement, you can file a formal complaint with the Calgary Assessment Review Board before the 67-day window closes.¹¹

The complaint fee is non-refundable. For residential properties with three or fewer dwellings, it’s $50, or $40 if the complaint is filed before January 31. For properties with four or more dwellings and all non-residential properties, it’s $650. Bring evidence: recent sales of comparable properties, a professional appraisal, or documentation of an error. The board can lower, raise, or leave your assessment unchanged.¹¹

Help if You Can’t Afford the Bill

Calgary runs a Property Tax Assistance Program for homeowners facing rising tax bills. It provides a credit or grant covering the year-over-year increase in your property tax. To qualify, you must have owned the property for at least 365 consecutive days by the end of the tax year and cannot own any other property in the city. Applications go through Fair Entry, the city’s centralized system for subsidized programs.¹²

If you or your spouse is 65 or older, the provincial Seniors Property Tax Deferral Program lets you defer all or part of your property taxes as a loan from the Alberta government. The current rate is 4.45% simple interest, charged only on the original loan amount from the date the province pays your bill. The rate is reviewed every six months, in April and October. The loan is repaid when the property is sold or ownership transfers.¹³

Extra Charges That May Show Up on Your Bill

Some properties see a local improvement charge for neighbourhood infrastructure work such as street paving, sidewalk replacement, lane paving, or curb and gutter installation. The charge includes financing costs and amortizes over a set period. You can pay off the remaining balance at any point to stop further interest.¹⁴

A handful of communities pay a separate Special Tax for boulevard or enhanced landscape maintenance. This applies in Christie Park, Citadel, Diamond Cove, Douglas Glen, Douglasdale, Edgemont, Hawkwood, McKenzie Lake, Patterson Hills, Royal Oak Estates, Valley Ridge, and Scenic Acres. The levy results from a community petition and requires annual City Council approval.¹⁴

If you bought a newly built home, your first tax bill typically covers only the vacant land value because the building hadn’t been assessed yet. Once the finished structure is assessed, you’ll get a supplementary tax bill prorated to the months construction was complete or the home was occupied during the year. If you’re on TIPP, your monthly payment automatically recalculates. If you’re not on TIPP and your closing was before June 30, the supplementary amount is due by June 30; if closing was after June 30, it’s due within 30 days of the supplementary bill.

School Support Designation

Every Calgary property owner should file a School Support Notice directing the education portion of the tax to either the public or the Roman Catholic separate school board. Roman Catholic owners must direct their tax to the separate district; other owners direct theirs to the public district. On a jointly owned property where one owner is Roman Catholic and the other isn’t, the tax splits based on each owner’s percentage.¹⁵

If no notice is filed, the property is deemed undeclared and the education tax goes to the Alberta School Foundation Fund, which distributes it equally per student across both boards. You can file or update your notice at any time online, by mail, or in person, but changes take effect only in the following tax year. The education portion cannot be directed to a private school.¹⁵
