The Calgary Landlord's Annual Compliance Calendar (2026)

Quick answer. Calgary landlord annual compliance touches five frameworks: the Alberta Residential Tenancies Act (lease renewals, deposit interest, rent increase notices, RTDRS deadlines), the Canada Revenue Agency (T776 filing by April 30 for personal taxpayers, June 15 for self-employed, T1 corporate returns within 6 months of year end), the City of Calgary (property tax due June 30, business license renewals where applicable, secondary suite registration), insurance (annual policy review and renewal, tenant insurance proof at each renewal), and operational maintenance (furnace service in fall, annual inspections, smoke detector and CO detector testing). A documented calendar reduces missed deadlines and the cascading consequences of falling behind.

January: New Year Reset

Confirm trust account interest rate for the year against Service Alberta's published Security Deposit Interest Rate Regulation.
Review and update the rental application form and lease template against any RTA amendments effective for the new year.
Confirm rent ledgers reconcile to bank statements for the prior year close.
Begin gathering documents for T776 tax filing: rent ledger, expense receipts, contractor invoices, mortgage interest statements, property tax bills.
Review landlord insurance renewal dates and prepare for any mid-year renewals.

February: Tax Preparation

Issue T5 slips to any persons paid interest in the prior year (rare for individual landlords).
Complete T776 preparation for personal tax filings due April 30.
Reconcile any year-end statements from the property manager against your own records.
Address any rent increase plans for spring effective dates; remember the 3 full tenancy months notice rule for periodic tenancies.

March: Furnace Filter and Smoke Detector Check

Schedule a spring property visit (with 24-hour written notice under section 23 of the RTA).
Test smoke and carbon monoxide detectors and replace batteries.
Replace furnace filters (typically every 3 months in winter, less often when furnace is off).
Conduct a visual exterior inspection: roof, eaves, downspouts, foundation, fence, deck.
Identify any spring maintenance items: yard work, gutter cleaning, exterior painting, deck staining.

April: Tax Filing and Spring Maintenance

File T776 with personal T1 by April 30 deadline.
Pay any balance owing to CRA by April 30.
Schedule any spring maintenance identified in March: gutter cleaning, yard cleanup, exterior repairs.
Coordinate any landlord-paid utility transfers if tenants are changing.
Confirm tenant insurance is current for every tenancy; request renewal proof if any policy has lapsed.

May: Leasing Season Begins

Calgary leasing season runs May to August. Prepare for any anticipated tenant turnover.
Refresh listing photos for vacant or upcoming-vacant units.
Update rent estimates against current rentfaster.ca comps.
Confirm any expiring fixed-term leases and engage tenants on renewal terms 60 to 90 days before expiry.
Issue any rent increase notices that need to take effect later in the year (3 full tenancy months notice for periodic tenancies).

June: Property Tax Due

Calgary property tax is due June 30 for the current year. Mark the date and pay on time to avoid penalties.
Set up the City of Calgary TIPP (Tax Installment Payment Plan) for the next year if not already enrolled.
Mid-year review of operating expenses vs budget.
Confirm rent collection patterns are healthy heading into summer.
Refresh photos and listings for any upcoming summer vacancies.

July: Mid-Year Insurance Review

Most Calgary landlord insurance policies renew in summer; review coverage limits against current Calgary construction costs.
Confirm hail coverage is in place (not auto-included in Alberta).
Confirm sewer backup endorsement limit is sufficient.
Confirm liability limit is appropriate for the property value and unit count.
Request and file proof of current tenant insurance from each tenant.

August: Renewal Season

Many Calgary leases turn over in August (tenants moving for the new school year or job changes).
Conduct move-out inspections within one week of vacancy under section 19 of the RTA.
Return security deposits with itemized statements within 10 days of vacancy.
Conduct move-in inspections within one week of new tenant possession.
Update lease files, tenant insurance, and trust account records for new tenancies.

September: Pre-Winter Furnace Service

Replace furnace filter.
Test heating in every unit before the cold weather arrives.
Confirm hot water tank function and check for signs of wear (rust, leaks).
Inspect window seals and weatherstripping for energy efficiency.

October: Annual Inspection Season

Conduct annual inspections with 24-hour written notice.
Photograph every room and compare to the move-in and prior annual inspection records.
Identify any maintenance items emerging from the inspection.
Confirm smoke and CO detectors are functional and replace batteries.
Test sump pumps if applicable.

November: Winter Preparation

Wrap exterior pipes and protect against freezing.
Confirm snow removal arrangements per the lease.

Begin gathering 2027 tax filing documents.
Review tenant relationships and identify any renewal or termination plans for the new year.

Quarterly Compliance Themes

Beyond the month-by-month calendar, four quarterly themes anchor Calgary landlord operations through the year.

Q1 (January-March): Tax and lease housekeeping

Q1 is dominated by the tax filing cycle and any rent increase notices needing time to take effect in Q2 or later. Calgary landlords with December year-end personal taxes should be gathering documentation in January and February for the April 30 deadline. Trust account interest rates published by Service Alberta should be confirmed in January and applied to any deposits returned during the year. Q1 is also a good time to update lease templates against any RTA amendments that took effect with the new calendar year.

Q2 (April-June): Leasing season and property tax

Q2 is the busiest operational quarter for Calgary landlords. The leasing season opens in May and runs through August, so listings, showings, and screening volumes spike. Calgary property tax is due June 30, and landlords not on the TIPP installment plan need to be ready for the full annual payment in one transaction. Q2 is the right time for spring exterior maintenance: gutters, eavestroughs, deck inspection, fence repair, lawn care setup, and any exterior painting that benefits from warm weather.

Q3 (July-September): Turnover and winter preparation

Q3 sees the highest concentration of tenant turnover in Calgary, especially August moves coordinated to the school calendar and job changes. Move-in and move-out inspections, security deposit returns within 10 days, and refreshed listings for new vacancies dominate operational time. September shifts focus to winter preparation: furnace service before the heating season, hot water tank check, smoke and carbon monoxide detector testing.

Q4 (October-December): Inspections and capex planning

Q4 is the right time for annual inspections with 24-hour written notice under section 23 of the RTA. The inspection cycle also informs capex planning for the following year: items approaching the end of useful life (furnaces at 15+ years, hot water tanks at 10+ years, roofs showing wear) should be flagged for replacement in the year ahead. December year-end reconciliation prepares the books for Q1 tax preparation.

Documentation Standards Across the Year

The calendar itself is only as useful as the documentation that supports each entry. Standards Calgary landlords should maintain:

Every notice served has a corresponding affidavit of service or equivalent proof in the tenant file.
Every inspection produces a signed report retained for at least three years after the tenancy ends under section 19 of the RTA.
Every contractor engagement produces an invoice with vendor details, scope of work, date, and amount.
Every rent payment is recorded in the ledger with date, amount, method, and applicable rental period within 24 hours of receipt.
Every communication with the tenant about a material issue (maintenance, rent, lease changes, RTDRS) is documented in writing.
Every insurance renewal, policy review, and claim file is retained.
Every CRA-filed document (T776, capital expenditure records, depreciation schedules) is retained for at least six years per CRA standard retention.

Frequently Asked Questions

When is Calgary property tax due?

June 30 for the current calendar year. The City of Calgary offers the TIPP (Tax Installment Payment Plan) for monthly installments instead of a single annual payment.

When does T776 need to be filed in Canada?

T776 is filed with the personal T1 return. The personal tax filing deadline is April 30 of the following year (June 15 if the taxpayer or spouse is self-employed, though any balance owing is still due April 30).

How often should I inspect a Calgary rental property?

Mandatory under section 19 of the RTA: move-in and move-out inspections within one week of possession changes. Recommended: an annual inspection with 24-hour written notice, often in October. Semi-annual inspections may be appropriate for higher-risk properties or after significant maintenance work.

What is the deadline for returning a security deposit in Alberta?

10 days from the date the tenant vacates and returns possession, per section 46 of the RTA. An itemized statement of account must accompany the return.

When should I service my Calgary rental property furnace?

Annually, ideally in September or early October before the heating season. Furnaces typically need filter changes more frequently (every 1 to 3 months) and full professional service annually.

What is the rent increase notice period in Alberta?

At least 3 full tenancy months for periodic tenancies. Fixed-term leases cannot have rent raised during the term; increases happen at renewal. The 365-day rule between increases applies in both cases.

When are landlord insurance policies typically renewed in Calgary?

Annually, often in the summer months. Review coverage carefully at each renewal against current Calgary construction costs, any changes to the property, and any changes to the insurance market.

Does Calgary require any business licensing for landlords?

Standard long-term residential rental does not require a City of Calgary business license. Short-term rentals (under 30 consecutive days) operating under the Short-Term Rental Bylaw require a city license, annual fees, and compliance with bylaw-specific safety and operational standards. Property managers acting for others must hold a RECA license under provincial regulation but not a city business license for residential management.

What happens if I miss the Calgary property tax deadline?

Penalties apply on unpaid balances after June 30 at rates set by the City of Calgary, typically with monthly compounding. The TIPP installment plan avoids the single-payment deadline by spreading the obligation across the year. If the property tax becomes seriously delinquent over multiple years, the City has authority to initiate tax-recovery sale proceedings.

When do I need to apply for a Calgary secondary suite registration?

If you have an existing unpermitted or non-conforming secondary suite, the Calgary Secondary Suites Amnesty Program waives development permit and registration fees until December 31, 2026. Applications and inspections should be initiated well before the deadline. The federal Housing Accelerator Fund supporting the $10,000 Secondary Suite Incentive Program may reach capacity before the deadline, so applying early protects the incentive.

How early should I issue a rent increase notice in Alberta?

For periodic tenancies, at least 3 full tenancy months before the new rent takes effect. For example, a rent increase intended to take effect September 1 must be served on or before May 31 (giving June, July, and August as the three full intervening tenancy months). Most Calgary landlords issue rent increase notices 4 to 6 months ahead to provide buffer for any service issues and tenant communication.

What documents should I have ready for an annual portfolio review?

Rent ledger reconciled to bank statements, every lease and amendment, every move-in and move-out inspection report, all maintenance records, insurance policies and certificates of insurance, property tax notices, mortgage statements, contractor invoices, year-end accounting statements from the property manager if applicable, and capex projection for the year ahead.

Bottom Line

A documented annual calendar transforms Calgary landlord operations from reactive to proactive. The deadlines that matter most are property tax (June 30), T776 filing (April 30), rent increase notices (3 full tenancy months), security deposit returns (10 days from vacancy), and pre-winter furnace service. Most disputes and missed deadlines trace back to inconsistent attention to these recurring obligations. UrbanLease maintains the full compliance calendar for owner-clients as part of one flat management fee, with year-end statements ready for tax filing in February each year.
