CORPORATION DECLARATION OF
ESTIMATED INCOME TAX
Purpose of Form Form 500D is used by a corporation to
declare and remit estimated income tax.
Corporations expected to be subject to estimated tax
requirements should use Form 500D to remit any payment
NOTE: Do not use this form to remit estimated tax for Form
510 or to remit employer withholding tax.
General Requirements Every corporation that reasonably
expects its Maryland taxable income to develop a tax in
excess of $1,000 for the tax year or period must make
estimated income tax payments. The total estimated tax
payments for the year must be at least 90% of the tax
developed for the current year or 110% of the tax that was
developed for the prior year to avoid interest and/or
penalty. At least 25% of the total estimated tax must be
remitted by each of the installment due dates. The
annualization method for calculating estimated tax is not
permitted for corporations.
In the case of a short tax period, the total estimated tax
payment required is the same as for a regular tax year: 90%
of the tax developed for the current (short) tax year or
110% of the tax that was developed for the prior tax year.
The minimum estimated tax for each of the installment due
dates is the total estimated tax required divided by the
number of installment due dates occurring during the short
tax year. However, if the corporation has a short tax period
of less than 4 months, it does not have to pay estimated
tax nor file Form 500D.
Maryland law provides for the accrual of interest and
imposition of penalty for failure to pay any tax when due.
If it is necessary to amend the estimate, recalculate the
amount of estimated tax required using the estimated tax
worksheet provided. Adjust the amount of the next
installment to reflect any previous underpayment or
overpayment. The remaining installments must be at least
25% of the amended estimated tax due for the year.
Consolidated returns are not allowed under Maryland law.
Affiliated corporations that file a consolidated federal return
must file separate Maryland declarations for each member
When to File File Form 500D on or before the 15th day of
the 4th, 6th, 9th and 12th months following the beginning

overpayment from the prior year Form 500 – Maryland
Corporation Income Tax Return to the estimated tax
obligation for this year.
