Tax Calendar – 2017

Here is a Quarter 1 calendar of the key tax-filing deadlines for 2017
Note: If a regular due date falls on a weekend or a national holiday, it is postponed to the next business day. If you operate on a fiscal-year schedule for tax purposes, rather than the usual calendar-year schedule, your due dates for each quarter will line up differently.

Using the 2017 calendar, here’s how you should calculate your deadlines:

 

Personal tax deadlines

Annual tax returns – Your personal tax return (Form 1040) is due on the 15th day of the fourth month following the close of your tax year.

Estimated tax payments – The first three quarterly installments of estimated tax (Form 1040-ES) are due on the 15th day of the fourth, sixth and ninth months of your tax year. The fourth and final installment is due on the 15th day of the first month following the close of your tax year.

 

Corporate tax deadlines

Annual tax returns – Your annual corporate return (Form 1120 or 1220-S) is due on the 15th day of the third month following the close of your corporation’s tax year. S corporations must provide each shareholder with a copy of Schedule K-1 or a substitute Schedule K-1.

Estimated tax payments – The quarterly installments of estimated taxes are due on the 15th day of the fourth, sixth, ninth and 12th months of the corporation’s tax year.

Switching to an S corp – The deadline is the 15th day of the third month of the year in which you want the election to apply. Make the election anytime in the preceding tax year (Form 2553).

 

Partnership tax deadlines

Annual returns – Your annual partnership return (Form 1065) is due on the 15th day of the fourth month following the close of the partnership’s tax year. Partnerships must provide each partner with a copy of Schedule K-1 or a substitute Schedule K-1.
