The deadline to file pass through entity business tax returns is today, and unless they are ready and filed by midnight, they will be subject to penalties and fees.
An extension will allow an additional six months to file the business return, so it will not need to be filed until September 15th, 2019.
The extension does not change when the actual taxes are due. Since the taxes resulting from a pass through entity will ultimately be due on the personal return, the payment of the taxes is due no later than April 15th, 2019. You can prevent the late filing fees and penalties by submitting an extension request for the business return today (and if applicable, for the state return), and avoid penalties and interest on the tax due by paying the estimated tax for the personal return by April 15th.
We wanted to alert you now, so that you will not be penalized for late filing, or for late payment of taxes owed.
Below is a link to IRS Form 7004 for the extension request, if you need more time.
and here are the instructions on how to file:
