Maryland Estimated Tax

For tax year 2008, you should file your quarterly estimated tax payments using this Form 502D (or your preprinted voucher) with your payment by the following dates:

First quarter - April 15, 2008
Second quarter - June 16, 2008
Third quarter - September 16, 2008
Fourth quarter - January 16, 2009

If the due date falls on a Saturday, Sunday or legal holiday, then the return or voucher would be due on the next business day.

If you file your first three quarterly payments, you don’t have to file and pay the fourth quarter estimated payment due on January 15 as long as you file your final individual return before January 31 and pay your full balance due with that return.
