City of Columbus Tax Increase Effective Oct. 1
Effective Oct. 1 the City of Columbus is implementing a 0.5% income tax increase. The increase reflects the passage of Issue 1 on the Aug. 4, 2009 ballot. You will see this change on the following pay dates:
- Biweekly paid: Oct. 23, 2009
- Monthly paid: Oct. 30, 2009
The tax rate increase impacts all individuals residing in as well as those working in the City of Columbus.
Columbus will continue to give full credit to residents for local tax paid to another tax jurisdiction. If the tax rate of the jurisdiction where a Columbus resident works is less than 2.5%, then the resident will owe additional tax to the City of Columbus so as to result in a total local tax paid of 2.5%.
Additional information on the tax increase can be found at www.columbustax.net.
