I have a tax extension - when are they now due?

The first extension is due August 15th. There is a way to extend until October 15th if you absolutely need to though.

The tax payment itself was due in April, you'll be paying interest/penalties if you owed. An extension is only for the return, not the money owed.

I agree with the answer above. A four month extension would make your tax return due August 15. I hope this answers your question. Thank you.

Well if it is your first extension then it would be due 3 or 6 months after the fact. Basically the extension will buy you an extra 6 months at the most. The latest you can push it off to would be 6 months after the 15th of April. If you are late after that you are in bad shape. There are two tax extensions one is 3 months the other would be the 6 month tax extension. You hopefully know which one you got. Most likely it would be the 3 month extension first. If you still need time you can buy another 3 months. It really depends on your current situation. However as I think someone stated above the longest you can get is until the date of the 15th of October.

The first extension is only until August 15, and only for filing the forms. Any tax that was due was due without any extension available on or before April 15. If you end up owing any tax with your extended return, you must also calculate and pay late payment penalties and interest; the interest grows every day. You can avoid adding interest even now if you contact the IRS and arrange to pay an estimated tax immediately.

A second extension is available until October 15, again, only for filing the documents. You have to apply for it before August 15, and you have to list a valid reason for requesting the additional time. There is no extension available beyond October 15. If you have not filed by that date, there may also be a late filing fee.

If your return results in a refund, there will not be any penalties. If you expect to pay, there will be late payment penalties and added interest, calculated daily until you pay in full. The sooner you pay, the lower that added interest. You should visit your tax preparer immediately to get this resolved.
