Grab your calendar, or put date alerts on your phone! Deadline for submitting 2017 Federal Income Tax Returns is April 17, 2018 [because of a weekend, and a Monday holiday in Washington DC].
Due dates for State Income Tax Returns vary by state. Due date for New Mexico state income tax returns is April 17, 2018. Date to file NM State Income Tax Extension is also April 17, 2018, at which time income tax return then becomes due by October 15, 2018.
** NOTE: Extension of time to file is NOT an extension of time to pay. If certain amounts due on 2017 tax returns (both Federal and New Mexico State returns) have not been paid by April 17, penalties may apply. E-Filing deadline and due date for Federal Income Tax Returns is from early January to October 15, 2018. E-Filing is suspended as of that date.
Corporations (C-corp, LLC, S-corp, partnerships, and other entities similarly-structured) business owners are required to file their income tax returns on the 15th day of the third month after the end of the tax year. For calendar-year corporations, the return is due by March 15. Think of this deadline as required of entities who must issue Schedule K-1 to various individuals, so that those individuals have time to include the K-1 in their personal tax returns.
And then there are Non-Profits returns, completed on Form 990, 990-EZ, or 990-PF. These entities must file by the 15th day of the 5th month after the end of the organization’s accounting period. Thus, for a calendar year NP taxpayer, these forms are due by May 15 following year-end 2017.
