Title 26 › Subtitle F — Procedure and Administration › CHAPTER 66 — LIMITATIONS › Subchapter B — Limitations on Credit or Refund › § 6513
Treats early tax returns and early payments as if they were made on the last day they were due. If you file a return or pay any part of a tax before its due date, the law counts the filing or payment as made on the final due date. That final due date is figured without counting any extension or a choice to pay in installments. For some payroll and withholding taxes tied to a calendar year, if the return or payment is made before April 15 of the next year, it is treated as filed or paid on April 15. One-line descriptions: tax withheld under chapter 24 — income tax taken from pay and sent to the government; estimated income tax — payments made ahead for the year; tax withheld under chapter 3 or 4 — tax taken from certain payments and sent to the government. Withheld tax under chapter 24 is treated as paid on the 15th day of the fourth month following the close of the taxpayer’s year. Estimated payments and many other withholdings are treated as paid on the regular return due date (no extensions). An overpayment applied to next year’s estimated tax counts as a payment for that next year and cannot be refunded for the earlier year. Payments of Federal unemployment tax made during a year but paid before the year’s return due date are treated as paid on that last day.
