TWIN FALLS, Idaho (KLIX) – You have a few more days this year to file your income tax return. The regular deadline date is April 15 – unless it falls on a holiday, like it does this year.

You didn't know about the holiday, did you?

Even though we’re not celebrating anything in south-central Idaho on Friday, the District of Columbia is celebrating, which affects us here in the Gem State and the rest of the country.

“The term ‘legal holiday’ includes a legal holiday observed in the District of Columbia,” reads the IRS Revenue Ruling 2015-13. “Emancipation Day, April 16, is a legal holiday in the District of Columbia. When April 16 is a Saturday, the preceding day is the observed holiday.”

Since Emancipation Day will be observed on Friday this year, it gets precedence over the April 15 tax deadline – and you get three more days to file your taxes.

“Therefore,” according to the IRS, “most individuals will have until Monday, April 18 … to file their income tax return.”
