A filled-in Form DE 938 example: a bakery adds unreported wages

Form DE 938 example filled out, example: a bakery adds unreported wages
Dana Sample's bakery files the DE 938 to correct its DE 3D. It found 5,000.00 in unreported wages, so it checks the box for only adjusting the DE 3D. The picture shows page 1, and every value in it is made up. The added wages raise only Total Subject Wages and VPDI Taxable Wages, so UI Taxable Wages stay 7,000.00, SDI Taxable Wages stay 0.00 and PIT Withheld stays 1,000.00. The rates are UI 3.4, ETT 0.1, SDI 1.1 and VPDI 0.5 percent. Line K is 0.00, 1,345.00 was paid on Line L, and the interest on Line O is 0.50. A balance is due and no credit is requested, so nothing goes in Line Q, SDI and PIT Overpayments because no credit is requested.
