How do I file my extended return electronically by 10/15/25 with small payment?

You can efile your return and say you will mail a check.   See this recent post

Not sure what you mean by "small payment."   Will the payment pay your tax due as shown on line 37 of your  Form 1040 in full?  Or is it a "partial" payment of the amount you owe the IRS?    You can tell the software that you will pay your tax by mailing a check and then pay by a variety of methods.  E-filing is available until October 15, 2025; after that your return has to be filed by mail.

 

 

 If you have federal tax due you can pay by mailing your payment with the 1040V voucher, (which has the address printed on it, having the payment taken out of a designated bank account, or you can pay directly on the IRS website.

You must pay your state tax due using the state’s preferred method of receiving payment.  For most states that will be by making a payment to the state’s own tax website, or by mailing a check or money order.
