If you pay late

Penalty after the due date; dates shift year to year.

Bills mailed in August. If a due date lands on a weekend or public holiday, most counties move it to the next business day — check the county's own notice before relying on the shift.

How to pay

Online: through www.fultoncountytaxes.org — the only portal this county operates.
By post: mail a cheque to the treasurer's office; the postmark date usually counts, not the arrival date.
In person: the treasurer's office during business hours; bring your bill or parcel number.
Mortgage escrow: if your taxes are escrowed, the servicer pays — you still owe the difference if your escrow is short.
