Veterans who served on active duty during the Cold War get a 10 or 15 percent reduction in the assessed value of their primary residence, whichever their taxing jurisdiction adopted, up to local maximum limits. If you have a service-connected disability you incurred while serving during the Cold War, you get a further reduction equal to half your disability rating. The base exemption lasts 10 years unless your taxing jurisdiction made it indefinite; the disability part has no time limit.
Apply to the assessor, or the city or town clerk, where the property is located. Ask whether your jurisdiction offers this exemption, which percentage it adopted, whether it made the exemption indefinite, and what the filing deadline is.
Official proof of honorable service between September 2, 1945 and December 26, 1991, and your VA disability documentation if you are claiming the disability reduction.
