Tax FAQ

Rate vs. Bill?

If a sales tax rate moves from 5% to 6%, that is a '1 percentage point' increase, but a '20% relative increase' in the tax burden.

Why did my property tax go up?

Either your local government raised the tax rate (mill rate), OR your property's assessed value went up. Often both happen at once.
