Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Gwinnett County Board of Assessors.
Relief programs
The filing guidance for this county is: April 1, 2026; Gwinnett's official property-tax brochure identifies April 1 as the annual personal-property-return deadline and the ordinary homestead deadline. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationGwinnett's official 2026 tax information identifies age-based school-tax exemptions and the county Value Offset Exemption; exact senior eligibility and amounts depend on the applicable program and must be confirmed with the Tax Commissioner.
Gwinnett County's Value Offset Exemption holds the assessed value constant for the county portion of qualifying homestead tax bills at the base-year value; it does not necessarily freeze school or city portions.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: 45 days after the Notice of Assessment is issued; Gwinnett's official Board of Assessors information states the 2026 appeal must be filed within that period. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
