Here are the key tax-filing deadlines for 2013.
Strategy: Keep this tax calendar handy for reference, when needed, during the year.
Note: If a regular due date falls on a weekend or 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 2013 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.
