If you’re trying to scrape up some extra money for the holidays, you might want to check with the Internal Revenue Service. I-R-S spokeswoman Donna Migazzi says about three thousand Iowans are due advanced tax credit payments, or are still owed refunds from past tax years. Migazzi says the I-R-S has been unable to locate the owners of the checks as the Postal Service doesn’t have any forwarding address.She says the checks add up to thousands of dollars.There are about 25-hundred advance tax credit payment checks worth about 783-thousand dollars, the tax refunds total from one dollar to over 11-thousand dollars. Migazzi says it’s easy to find out if you’re owed money, just call the I-R-S at 1-800-Tax-1040. Migazzi says a deadline is approaching for advance tax credit payments.You need to contact the I-R-S by December 5th to have it paid by the end of the year, or you have to claim it on next year’s taxes as a credit.
