Reg. § 301.7502-1 Timely mailing of documents and payments treated as timely filing and paying.

26 CFR § 301.7502-1eCFR, current through 2026-07-14

(a) General rule Section provides that, if the requirements of that section are met, a document or payment is deemed to be filed or paid on the date of the postmark stamped on the envelope or other appropriate wrapper (envelope) in which the document or payment was mailed. Thus, if the envelope that contains the document or payment has a timely postmark, the document or payment is considered timely filed or paid even if it is received after the last date, or the last day of the period, prescribed for filing the document or making the payment. Section does not apply in determining whether a failure to file a return or pay a tax has continued for an additional month or fraction thereof for purposes of computing the penalties and additions to tax imposed by section . Except as provided in section and , relating to the timely mailing of deposits, and of this section, relating to electronically filed documents, section is applicable only to those documents or payments as defined in of this section and only if the document or payment is mailed in accordance with of this section and is delivered in accordance with of this section.

(b) Definitions

(1) Document defined

(i) The term document, as used in this section, means any return, claim, statement, or other document required to be filed within a prescribed period or on or before a prescribed date under authority of any provision of the internal revenue laws, except as provided in , , or of this section.

(ii) The term does not include returns, claims, statements, or other documents that are required under any provision of the internal revenue laws or the regulations thereunder to be delivered by any method other than mailing.

(iii) The term does not include any document filed in any court other than the Tax Court, but the term does include any document filed with the Tax Court, including a petition and a notice of appeal of a decision of the Tax Court.

(iv) The term does not include any document that is mailed to an authorized financial institution under section . However, see for special rules relating to the timeliness of deposits and documents required to be filed with deposits.

(2) Claims for refund

(i) In general In the case of certain taxes, a return may constitute a claim for credit or refund. Section is applicable to the determination of whether a claim for credit or refund is timely filed for purposes of section if the conditions of section are met, irrespective of whether the claim is also a return. For rules regarding claims for refund on late filed tax returns, see of this section. Section is also applicable when a claim for credit or refund is delivered after the last day of the period specified in section or in any other corresponding provision of law relating to the limit on the amount of credit or refund that is allowable.

(ii) Example The rules of of this section are illustrated by the following example:

Example.

(A) Taxpayer A, an individual, mailed his 2004 Form 1040, “U.S. Individual Income Tax Return,” on May 10, 2005, but no tax was paid at that time because the tax liability disclosed by the return had been completely satisfied by the income tax that had been withheld on A's wages. On April 15, 2008, A mails, in accordance with the requirements of this section, a Form 1040X, “Amended U.S. Individual Income Tax Return,” claiming a refund of a portion of the tax that had been paid through withholding during 2004. The date of the postmark on the envelope containing the claim for refund is April 15, 2008. The claim is received by the IRS on April 18, 2008.

(B) Under section , A's claim for refund is timely if filed within three years from May 10, 2005, the date on which A's 2004 return was filed. As a result of the limitations of section , if A's claim is not filed within three years after April 15, 2005, the date on which A is deemed under section to have paid his 2004 tax, A is not entitled to any refund. Because A's claim for refund is postmarked and mailed in accordance with the requirements of this section and is delivered after the last day of the period specified in section , section is applicable and the claim is deemed to have been filed on April 15, 2008.

(3) Payment defined

(i) The term payment, as used in this section, means any payment required to be made within a prescribed period or on or before a prescribed date under the authority of any provision of the internal revenue laws, except as provided in , , , or of this section.

(ii) The term does not include any payment that is required under any provision of the internal revenue laws or the regulations thereunder to be delivered by any method other than mailing. See, for example, section and the regulations thereunder regarding electronic funds transfer.

(iii) The term does not include any payment, whether it is made in the form of currency or other medium of payment, unless it is actually received and accounted for. For example, if a check is used as the form of payment, this section does not apply unless the check is honored upon presentation.

(iv) The term does not include any payment to any court other than the Tax Court.

(v) The term does not include any deposit that is required to be made with an authorized financial institution under section . However, see for rules relating to the timeliness of deposits.

(4) Last date or last day prescribed As used in this section, the term the last date, or the last day of the period, prescribed for filing the document or making the payment includes any extension of time granted for that action. When the last date, or the last day of the period, prescribed for filing the document or making the payment falls on a Saturday, Sunday or legal holiday, section applies. Therefore, in applying the rules of this , the next succeeding day that is not a Saturday, Sunday, or legal holiday is treated as the last date, or the last day of the period, prescribed for filing the document or making the payment. Also, when the last date, or the last day of the period, prescribed for filing the document or making the payment falls within a period disregarded under section or section , the next succeeding day after the expiration of the section period or section period that is not a Saturday, Sunday, or legal holiday is treated as the last date, or the last day of the period, prescribed for filing the document or making the payment.

(c) Mailing requirements

(1) In general Section does not apply unless the document or payment is mailed in accordance with the following requirements:

(i) Envelope and address The document or payment must be contained in an envelope, properly addressed to the agency, officer, or office with which the document is required to be filed or to which the payment is required to be made.

(ii) Timely deposited in U.S. mail The document or payment must be deposited within the prescribed time in the mail in the United States with sufficient postage prepaid. For this purpose, a document or payment is deposited in the mail in the United States when it is deposited with the domestic mail service of the U.S. Postal Service. The domestic mail service of the U.S. Postal Service, as defined by the Domestic Mail Manual as incorporated by reference in the postal regulations, includes mail transmitted within, among, and between the United States of America, its territories and possessions, and Army post offices (APO), fleet post offices (FPO), and the United Nations, NY. (See Domestic Mail Manual, section G011.2.1, as incorporated by reference in 39 CFR 111.1.) Section does not apply to any document or payment that is deposited with the mail service of any other country.

(iii) Postmark

(A) U.S. Postal Service postmark If the postmark on the envelope is made by the U.S. Postal Service, the postmark must bear a date on or before the last date, or the last day of the period, prescribed for filing the document or making the payment. If the postmark does not bear a date on or before the last date, or the last day of the period, prescribed for filing the document or making the payment, the document or payment is considered not to be timely filed or paid, regardless of when the document or payment is deposited in the mail. Accordingly, the sender who relies upon the applicability of section assumes the risk that the postmark will bear a date on or before the last date, or the last day of the period, prescribed for filing the document or making the payment. See, however, of this section with respect to the use of registered mail or certified mail to avoid this risk. If the postmark on the envelope is made by the U.S. Postal Service but is not legible, the person who is required to file the document or make the payment has the burden of proving the date that the postmark was made. Furthermore, if the envelope that contains a document or payment has a timely postmark made by the U.S. Postal Service, but it is received after the time when a document or payment postmarked and mailed at that time would ordinarily be received, the sender may be required to prove that it was timely mailed.

(B) Postmark made by other than U.S. Postal Service

(1) In general If the postmark on the envelope is made other than by the U.S. Postal Service—

(i) The postmark so made must bear a legible date on or before the last date, or the last day of the period, prescribed for filing the document or making the payment; and

(ii) The document or payment must be received by the agency, officer, or office with which it is required to be filed not later than the time when a document or payment contained in an envelope that is properly addressed, mailed, and sent by the same class of mail would ordinarily be received if it were postmarked at the same point of origin by the U.S. Postal Service on the last date, or the last day of the period, prescribed for filing the document or making the payment.

(2) Document or payment received late If a document or payment described in paragraph (c)(1)(iii)(B)(1) is received after the time when a document or payment so mailed and so postmarked by the U.S. Postal Service would ordinarily be received, the document or payment is treated as having been received at the time when a document or payment so mailed and so postmarked would ordinarily be received if the person who is required to file the document or make the payment establishes—

(i) That it was actually deposited in the U.S. mail before the last collection of mail from the place of deposit that was postmarked (except for the metered mail) by the U.S. Postal Service on or before the last date, or the last day of the period, prescribed for filing the document or making the payment;

(ii) That the delay in receiving the document or payment was due to a delay in the transmission of the U.S. mail; and

(iii) The cause of the delay.

(3) U.S. and non-U.S. postmarks If the envelope has a postmark made by the U.S. Postal Service in addition to a postmark not so made, the postmark that was not made by the U.S. Postal Service is disregarded, and whether the envelope was mailed in accordance with this will be determined solely by applying the rule of of this section.

(2) Registered or certified mail If the document or payment is sent by U.S. registered mail, the date of registration of the document or payment is treated as the postmark date. If the document or payment is sent by U.S. certified mail and the sender's receipt is postmarked by the postal employee to whom the document or payment is presented, the date of the U.S. postmark on the receipt is treated as the postmark date of the document or payment. Accordingly, the risk that the document or payment will not be postmarked on the day that it is deposited in the mail may be eliminated by the use of registered or certified mail.

(3) Private delivery services Under section , a service of a private delivery service (PDS) may be treated as an equivalent to United States mail for purposes of the postmark rule if the Commissioner determines that the service satisfies the conditions of section . Thus, the Commissioner may, in guidance published in the Internal Revenue Bulletin (see ), prescribe procedures and additional rules to designate a service of a PDS for purposes of the postmark rule of section .

(d) Electronically filed documents

(1) In general A document filed electronically with an electronic return transmitter (as defined in of this section and authorized pursuant to of this section) in the manner and time prescribed by the Commissioner is deemed to be filed on the date of the electronic postmark (as defined in of this section) given by the authorized electronic return transmitter. Thus, if the electronic postmark is timely, the document is considered filed timely although it is received by the agency, officer, or office after the last date, or the last day of the period, prescribed for filing such document.

(2) Authorized electronic return transmitters The Commissioner may enter into an agreement with an electronic return transmitter or prescribe in forms, instructions, or other appropriate guidance the procedures under which the electronic return transmitter is authorized to provide taxpayers with an electronic postmark to acknowledge the date and time that the electronic return transmitter received the electronically filed document.

(3) Definitions

(i) Electronic return transmitter For purposes of this , the term electronic return transmitter has the same meaning as contained in of Rev. Proc. 2000-31 (2000-31 I.R.B. 146 (July 31, 2000))(see ) or in procedures prescribed by the Commissioner.

(ii) Electronic postmark For purposes of this , the term electronic postmark means a record of the date and time (in a particular time zone) that an authorized electronic return transmitter receives the transmission of a taxpayer's electronically filed document on its host system. However, if the taxpayer and the electronic return transmitter are located in different time zones, it is the taxpayer's time zone that controls the timeliness of the electronically filed document.

(e) Delivery

(1) General rule Except as provided in section and and of this section, section is not applicable unless the document or payment is delivered by U.S. mail to the agency, officer, or office with which the document is required to be filed or to which payment is required to be made.

(2) Exceptions to actual delivery

(i) Registered and certified mail In the case of a document (but not a payment) sent by registered or certified mail, proof that the document was properly registered or that a postmarked certified mail sender's receipt was properly issued and that the envelope was properly addressed to the agency, officer, or office constitutes prima facie evidence that the document was delivered to the agency, officer, or office. Other than direct proof of actual delivery, proof of proper use of registered or certified mail, and proof of proper use of a duly designated PDS as provided for by of this section, are the exclusive means to establish prima facie evidence of delivery of a document to the agency, officer, or office with which the document is required to be filed. No other evidence of a postmark or of mailing will be prima facie evidence of delivery or raise a presumption that the document was delivered.

(ii) Equivalents of registered and certified mail Under section , the Secretary may extend the prima facie evidence of delivery rule of section to a service of a designated PDS, which is substantially equivalent to United States registered or certified mail. Thus, the Commissioner may, in guidance published in the Internal Revenue Bulletin (see ), prescribe procedures and additional rules to designate a service of a PDS for purposes of demonstrating prima facie evidence of delivery of a document pursuant to section .

(f) Claim for credit or refund on late filed tax return

(1) In general Generally, an original income tax return may constitute a claim for credit or refund of income tax. See . Other original tax returns can also be considered claims for credit or refund if the liability disclosed on the return is less than the amount of tax that has been paid. If section would not apply to a return (but for the operation of of this section) that is also considered a claim for credit or refund because the envelope that contains the return does not have a postmark dated on or before the due date of the return, section will apply separately to the claim for credit or refund if—

(i) The date of the postmark on the envelope is within the period that is three years (plus the period of any extension of time to file) from the day the tax is paid or considered paid (see section ), and the claim for credit or refund is delivered after this three-year period; and

(ii) The conditions of section are otherwise met.

(2) Filing date of late filed return If the conditions of of this section are met, the late filed return will be deemed filed on the postmark date.

(3) Example The rules of this are illustrated by the following example:

Example.

(i) Taxpayer A, an individual, mailed his 2001 Form 1040, “U.S. Individual Income Tax Return,” on April 15, 2005, claiming a refund of amounts paid through withholding during 2001. The date of the postmark on the envelope containing the return and claim for refund is April 15, 2005. The return and claim for refund are received by the Internal Revenue Service (IRS) on April 18, 2005. Amounts withheld in 2001 exceeded A's tax liability for 2001 and are treated as paid on April 15, 2002, pursuant to section .

(ii) Even though the date of the postmark on the envelope is after the due date of the return, the claim for refund and the late filed return are treated as filed on the postmark date for purposes of this . Accordingly, the return will be treated as filed on April 15, 2005. In addition, the claim for refund will be treated as timely filed on April 15, 2005. Further, the entire amount of the refund attributable to withholding is allowable as a refund under section .

(g) Effective date

(1) In general Except as provided in and of this section, the rules of this section apply to any payment or document mailed and delivered in accordance with the requirements of this section in an envelope bearing a postmark dated after January 11, 2001.

(2) Claim for credit or refund on late filed tax return of this section applies to any claim for credit or refund on a late filed tax return described in of this section except for those claims for credit or refund which (without regard to of this section) were barred by the operation of section or any other law or rule of law (including res judicata) as of January 11, 2001.

(3) Electronically filed documents This section applies to any electronically filed return, claim, statement, or other document transmitted to an electronic return transmitter that is authorized to provide an electronic postmark pursuant to of this section after January 11, 2001.

(4) Registered or certified mail as the means to prove delivery of a document will apply to all documents mailed after September 21, 2004.
