When Are Property Taxes Due in Georgia?

By Tanika Hall · October 2026 · 3 min read

There's no single property tax due date in Georgia, which is part of why people get caught. The state sets a default and then lets each county pick its own schedule. So the honest answer to "when is it due" is: it depends on your county, and you need to know yours.

The Georgia default

The default due date is December 20. Counties can move it to December 1 or November 15 or bill in installments. Many choose their own date entirely. You get 60 days from the postmark on your bill before interest starts.

Cobb County

Cobb mails bills by August 15, and they're due October 15. Your payment has to be received or postmarked by the U.S. Postal Service by that date. A metered or kiosk postmark doesn't count. Late payments get a 5% penalty plus monthly interest, and Cobb says late fees can't be waived. If you're reading this in late October and haven't paid, pay now. The penalty only grows.

If you're in another county, your bill and your tax commissioner's website will show the date. Put it in your calendar the day the bill arrives.

If your mortgage company pays it

Most people with a mortgage pay property tax through escrow. The lender collects a slice each month and pays the county when the bill comes due. Easy, right? Mostly. Two things trip people up:

When taxes go up, your escrow payment goes up too, usually after your lender's yearly escrow analysis. I wrote a separate guide on escrow shortages because that letter surprises a lot of people.

Deducting property tax on your federal return

You deduct property tax in the year it's actually paid. If you pay through escrow, you deduct what the lender paid to the county that year, not what you put into escrow. Your lender's year-end statement shows it. There's a cap on the state and local tax deduction, which for 2026 is $40,400 for most filers ($20,200 married filing separately). It phases down when modified adjusted gross income is over $505,000 ($252,500 married filing separately), but not below $10,000.

Landlords: property tax on a rental goes on Schedule E as a rental expense, not on your personal itemized deductions, and it doesn't count toward the SALT cap. More in rental property tax deductions.
