Your cancelled check will be your receipt. If an alternate receipt is desired, send the entire bill (including the taxpayer copy just as it was mailed to you) and a self addressed, stamped envelope with your payment. We will date stamp “paid” on your taxpayer copy and mail it back to you. On the second payment in January, again mail us the taxpayer copy along with the second payment due coupon and we will stamp the taxpayer copy for the second time and mail it back to you.Please retain the stamped copy for your records. This may be needed when filing state and government taxes each year.
