I recently received a letter from the city of Xenia informing me that I overpaid my income tax to the city for 2009. It was nice of them to inform me and be honest about my mistake; but no refund check was included, and there was no indication of when the surplus amount would be refunded to me.
The letter simply stated that my overpayment would be applied to the next year's tax filing…I guess in case of under-payment on my part, the City of Xenia is holding my 2009 over-payment as collateral, as an interest-free loan.
