1- Get your property taxes deferred. Single? Do you make less than $50K a year? Then you may be able to get a deferment. Unfortunately this doesn’t look like the same deferment I had. Those were 5 wonderful years of not paying any property tax, then one year, I made about $500 too much, and that was the end of that. It looks like you fill out the second (1st half is for old people) part of form FP-110.
2- Are you 65 years or older OR do you receive SSDI? Pay less on your property taxes than those suckers with just a Homestead Deduction. Go to the forms page, fill out FP-100.
3- Did you for some odd reason not take the $5000 if you bought during or before 2011, the 1st time homeowner tax credit? Really? That was just free money. Since there can’t be too many people that qualify for this, I’m going to move on.
4- Do you make $20K or less? You don’t have to be a homeowner for this, renters can qualify. On your DC state income tax, fill out Schedule H, you’ll get a credit.
