Homestead exemption is a reduction in the assessed valuation of the real estate you use as your main home (which results in an overall lower real estate tax bill). The exemption is not entered anywhere on your federal income tax return.
Homestead exemptions are usually filed at your county courthouse, at the tax assessor's office.
You may also apply in person at 75 Langley Drive in Lawrenceville, or by mailing your application to P.O. Box 372, Lawrenceville, GA 30046. We recommend U.S.P.S. certified mail. Metered dates are not accepted as timely.
The deadline to apply for all homestead exemptions is April 1.
