Not necessarily.
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.
