Johns Creek property owners have until Friday, July 31, to challenge their 2026 assessed values with the Fulton County Board of Assessors, a deadline that arrives one week after the board reviews the latest digest data and appeal outcomes at its Friday, July 24, meeting.

The county mailed Notices of Assessment to all property owners on June 16, starting a 45-day appeal clock created by state Senate Bill 141, which extended the old 30-day window. Notices are also available at fultonassessor.org.

District 1 Commissioner Bridget Thorne, who represents Johns Creek on the Fulton County Board of Commissioners, is hosting two Property Tax Assessment Town Halls for residents on Thursday, July 23, and Tuesday, July 28. Thorne promoted the events on her Facebook page, inviting residents with questions about their 2026 notices.

Specific times and locations for the town halls had not been confirmed in county records as of Tuesday, July 21. Residents can check the Fulton County calendar at fultoncountyga.gov for details.

What's different on the 2026 notice

This year's assessments reflect changes required by state Senate Bill 566, effective for the 2026 tax year. Instead of showing an estimated rollback rate or tax liability, notices now display each taxpayer's Estimated Tax Savings, including applicable discounts and exemptions. The notices also show fair market value rather than the 40% assessed value shown in prior years.

A sample notice in the county's official guide shows a Johns Creek property with a 2025 and 2026 fair market value of $592,500. The Johns Creek tax district carried a total market value of $22.2 billion in 2025, according to the Board of Assessors' annual report.

The notices are not tax bills. Each of the 18 taxing jurisdictions in Fulton County will set its own millage rate later this summer, and actual tax bills will follow.

How to appeal

Property owners can appeal if they believe their assessed value is too high, does not reflect the property's condition, or does not match recent sales of comparable homes. The preferred method is filing online at fultonassessor.org. Appeals can also be mailed or hand-delivered to the Board of Assessors' main office at 235 Peachtree St. NE, Suite 1200, Atlanta. The board will not accept appeals by email or fax.

If an appeal has not been resolved when tax bills are mailed, owners must pay the temporary bill to avoid penalties. Once the appeal is resolved, the bill will be recalculated. Billing questions go to the Fulton County Tax Commissioner's office at 404-613-6100.

Missed the homestead deadline?

Homeowners who owned their property as of January 1, 2026, and qualified for a homestead exemption but missed the April 1 application deadline can still apply during the appeal window through July 31. That includes new senior exemptions for Fulton County Schools created by the Georgia General Assembly and adopted by voters in 2025.

What's on the July 24 agenda

The Board of Assessors meets Friday, July 24, at 12:30 p.m. at 235 Peachtree St. NE, Suite 1400, Atlanta. Chief Appraiser Roderick Conley will present a 2026 Digest Update. The agenda also includes residential administrative changes, 2025 appeal value changes, 2026 appeal withdrawals, and settlement conference agreements for residential properties. The board is chaired by Lee Morris.

The appeal deadline is Friday, July 31. Residents can reach the Board of Assessors at 404-612-6440.
