Does Form 4868 extend the time to pay my taxes?

No. The IRS states Form 4868 extends only your time to file, not your time to pay. You should estimate and pay any tax owed by the regular due date to limit interest and possible penalties.

How long is the extension?

Most filers get an automatic 6-month extension (to October 15 for a calendar-year return). Filers who are 'out of the country' may have a different period — see the IRS instructions on the form.

Does AttachKit file Form 4868 with the IRS?

No. AttachKit only helps you fill the PDF in your browser. It does not submit the form, calculate your tax, or fill the Part II tax lines. You file the completed form with the IRS yourself.
