Do not combine sales and use tax refunds on the same claim; file a separate claim for each tax account type. If you are submitting this claim for a third party, you must include a Power of Attorney (DR 0145). Keep all documentation supporting refund claims at the location of your business records. For assistance in determining the breakdown of the tax rate on your invoice, see publication DR 1002.
