What is 'IRS Publication 509: Tax Calendars'

IRS Publication 509: Tax Calendars is a document published by the Internal Revenue Service (IRS) that provides the dates on which tax forms and tax payments are due. IRS Publication 509 covers due dates for both individual taxpayers and employers, as well as which other IRS documents should be examined for further information. 

BREAKING DOWN 'IRS Publication 509: Tax Calendars'

IRS Publication 509: Tax Calendars reamains primarily of interest to businesses; self-employed individuals; and workers who earn tips as part of their compensation. Regular wage earners whose taxes are withheld by their employer have no need to consult the tax calendar.

But for businesses and individuals who need to schedule frequent tax payments to the IRS, Publication 509 provides timely reminders of due dates for any type of payment. For example, the IRS divides the 12-month calendar into quarters and requires some tax payments, such as estimated individual taxes, to be made each quarter. The regular dates for quarterly tax payments are April 15, June 15, September 15 and January 15; the payment for the final quarter of the year is held off until January to give taxpayers a break during the busy December holiday period.

However, when quarterly payment dates fall on a weekend or holiday, the due date is the following business day. This is often an issue in January because the 15th of that month sometimes falls on Martin Luther King Day; and in April, when the 15th can fall on Emancipation Day, a Washington DC holiday during which the IRS is closed. Residents of some states also get an extra day when certain state holidays fall on the 15th. Publication 509 lists all of these dates and exceptions for every year.

Important Dates for Individuals...

Other important dates on the tax calendar for individuals include the 10th of every month, when tipped employees must file Form 4070 to their employers, detailing their tipped income for the previous month; and October 15, which is the date that anyone who has requested a six-month extension on their annual tax return must file their 1040, 1040A or 1040EZ.

...and for Businesses

For businesses, important dates include January 31, when businesses must send Form 1099 statements to contractors and freelancers who have been paid non-employee compensation during the previous year; and March 15, when partnerships must provide partners with Schedule K-1 detailing loss or gain for the previous year;

While most important tax dates are covered in the document, due dates for certain tax types, such as estate, gift and trust taxes, are not included.
