For Calendar Year Taxpayers Only

Please keep in mind that the calendar below is for calendar year taxpayers only, that is, taxpayers whose tax year runs from January 1 – December 31.  If you or your business use a fiscal year as your tax year, you’ll have to figure out your tax deadlines separately.

Nobody likes paying taxes, but it’s something we all have to do.  And it’s especially important that you pay your taxes timely unless you want to incur a penalty from the IRS and possibly your state or local taxing authority as well.

The tax deadline calendar below is categorized by type of taxpayer.  Most IRS tax calendars online simply give all the deadlines in chronological order, but I personally think organizing the calendar by entity makes it a bit easier to navigate.

Individual Deadlines

January 15, 2020: Make Q4 2019 Estimated Tax Payment

If you still owe estimated taxes for tax year 2019, you should make your fourth quarter payment using Form 1040-ES by January 15 to avoid incurring a Q4 estimated tax penalty.

Exception: If you file your 2019 tax return and pay any tax due by January 31, 2020, you can likewise avoid a Q4 estimated tax penalty.

February 17, 2020: Give Employer Updated Form W-4

This deadline only applies to a minority of individual taxpayers, namely those that claimed an exemption from income tax withholding in 2019.

If you claimed such an exemption, you must give your employer a new Form W-4 by February 17 to continue your exemption throughout 2020.

Either way, if your S corporation owes tax, it should be paid by March 16 to avoid a late payment penalty.

S Corporation Owing Tax? Say What?

I know what you’re thinking, “Wait, what did you just say about S corporations owing tax?  I thought that S corps were passthrough entities, meaning that they don’t pay any income tax themselves but rather the shareholders pay tax on what’s reported to them on their K-1s.”  Relax; you’re right.  This is the case for the vast majority of S corps.  But some S corps that previously existed as C corporations may have some “leftover” tax due from their C corp years.

If you extended your S corporation tax return for six months using Form 7004, September 15 is the extended due date of your return.  By this date, you must file Form 1120S and provide each shareholder with a copy of their Schedule K-1 to avoid incurring a late filing penalty.
