Questions people ask
Can an overpayment be applied to next year’s tax?
Yes. Enter the amount of your overpayment you want applied to your 2026 tax on line 46. Subtract that amount from line 45 to determine the refund on line 47.
What information is needed for direct deposit?
Provide the routing number and account number, and select checking or savings. Mark the box if the refund is going to an account outside the United States or its territories.
What extra entries are needed for an amended return?
Mark the amended return box. Line 38 is for previously issued refunds, and line 39 is for payments made with the original return.
What if there are more than 10 composite tax participants?
Attach a statement with the same information requested in Schedule IV. Report the total composite tax from those statements on line 11 of Part IV.
