Most taxpayers have until Wednesday, April 15, 2015, to file their 2014 tax returns and pay any tax due. Consistently, April 15th of each year is the official day that most taxes are due.
Partnerships and corporations and other employers may have different dates. It's always best to check the IRS Publication 509 (2014). More information about how to file taxes, when payments are due, and whether or not a tax return is required can be found at the following website: www.irs.gov.
