How Potomac compares
Think your bill is too high?
Divide your yearly tax by your home's market value. If your result is well above what neighbors with similar homes pay, your assessed value may be too high or an exemption may be missing.
- Check the market value on your notice against recent sales nearby.
- Make sure every exemption you qualify for is listed, starting with the homestead exemption.
- File an appeal before the deadline. Filing is usually free or costs little.
