You can claim a credit for part of the real estate tax or rent you paid for the year if you have a 100 percent service-connected disability rating from the VA. The credit is up to $750 if you rent and up to $1,100 if you own your home, and it is limited by household income.
The source says to contact the county assessor's office where the property is located. The credit itself is claimed on a Missouri Property Tax Credit claim filed with the Department of Revenue, so check the qualification chart and confirm with the Department of Revenue before relying on the county.
