Lake of Bays Airbnb MAT 2026: How to Report and Pay

The Township of Lake of Bays launched a 4% Municipal Accommodation Tax on January 1, 2026. It is filed quarterly, and Airbnb does not collect it for you, so the responsibility is yours.

Here is how the new tax works and how to file it.

New for 2026

Lake of Bays Council passed the MAT under By-law 2025-139, effective January 1, 2026, at 4% of the accommodation cost. One helpful transition rule: reservations made before January 1, 2026 are not subject to the tax, even if the stay happens in 2026.

Airbnb Does Not Collect It

Straight from the Township: "Airbnb does not collect the MAT on behalf of the Township of Lake of Bays hosts." Airbnb does offer an "add tax" feature in its professional hosting tools, but the collecting and remitting is on you. You file and pay 4% on all qualifying bookings.

The Rate and What It Applies To

The rate is 4% of the accommodation cost, applied to hotels, motels, bed and breakfasts, and licensed short-term rentals offering stays of less than 30 continuous days. The MAT must appear as a separate charge on the accommodation portion of each guest invoice. HST is also payable on the MAT portion. Note that a valid short-term rental licence is required to operate; the Township states that renting without one is unlawful.

How to File and Pay

Lake of Bays uses a single online form for both filing and payment.

1

Open the remittance form

Go to the Township's Municipal Accommodation Tax Quarterly Remittance Form on its webforms site.

2

Enter your numbers

Provide your contact details, the reporting period, your total accommodation revenue subject to MAT, and the tax payable, then complete the attestation.

3

Choose a payment option

Pay securely online by major credit card at the end of the form, or pay in person (cash, debit, cheque, or money order) at the Municipal Office, or mail a cheque, certified cheque, or money order payable to The Township of Lake of Bays, Attn: Finance Department, 1012 Dwight Beach Road, Dwight, ON P0A 1H0.

To clear an outstanding balance, file the overdue quarter on the same form and pay by one of the methods above.
