Paper Sales Tax Returns to Receive Closer Look

Posted: January 10, 2012


Beginning with January sales tax returns due in February, businesses that file state sales tax returns on paper must completely and accurately fill out the form to avoid math adjustments that may result in more tax due and billing notices. The department's tax accounting system enables the state to conduct detailed reviews of paper sales tax returns and detect errors more efficiently.

On the DR 0100 paper return, line 4 must equal line 1. If these amounts are different, the deductions must be reported on lines 2a and 2b and the exemptions must be reported on lines 3a, 3b and 3c.
