Instructions to Part 3
In the first line of each quarter, Part 3, Column C, enter the required payment from Part 2, line 9. Then complete each line across before
proceeding to the next line. Column C in each quarter must be brought to zero, unless all payments have already been applied, before
proceeding to the next quarter.
Column A-
Enter the date the estimated tax payment(s) was actually paid. Estimated tax payments and withholding payments which
are paid on or before the quarterly due date are considered timely paid; therefore, the date is preprinted on the form. Any
balance due, paid with your tax return, is considered a payment for this purpose and should be listed, using the date you
filed your return or the original due date, whichever is earlier.
Enter payments according to the date paid or deemed paid, the earliest date of payment being applied first. Only use the
Column B-
portion of a payment necessary to bring the balance due to zero.
Withholding payments are deemed paid on the quarterly due date(s). Enter on the withholding line tax(es) withheld, on or
before the quarterly due date, that have not been applied to a previous quarter.
Enter on the estimated tax line estimated tax payments paid on or before the quarterly due date, which have not been
applied to a previous quarter.
Enter on the tax payment line(s) any payment made after the quarterly due date. If more lines are needed for tax pay-
ments, list each payment separately on an attached schedule using Columns A through E.
Column C-
Compute the balance due after each payment. If there are no payments entered on the withholding and estimated tax
lines, bring the required payment down to the estimated tax line in Column C and complete Columns D & E.
Column D-
Column C balance, for each line, is considered past due until the next payment is made. Compute the number of days
past due from the date of this payment until the date of the next payment or the original due date of the return, if no pay-
ment is made.
Column E-
Column C x Number of days in Column D x 20%
divided by 365
