Columbia Association Fees

If you locate your business within the boundaries of Howard County that are part of the Columbia Association, there is an association fee that applies. The current rate has been set to a maximum of 75 cents per $100 of valuation assessed on 50 percent of the fair market value, as determined by the State of Maryland for real estate tax purposes. The Columbia Association applies the same methodology used by Howard County and the State with respect to their caps on property taxes, and they don’t apply those caps in calculating taxes due on a property in the year following the purchase.  In FY2011, the annual charge rate was 68 cents.
