Maryland Estimated Tax Payments 2026

Maryland’s test is dollars of tax in excess of withholding: if you must file a Maryland return and no tax (or not enough) was withheld, estimated payments are required once the tax would be more than $500.

• If you must file a Maryland return and no tax (or not enough) was withheld, you must pay estimated tax when your gross income would develop a tax of more than $500 in excess of any withholding.

  “If you are required to file a Maryland income tax return, and no taxes were withheld (or not enough), and your gross income would be expected to develop a tax of more than $500 in excess of any withholding, then you must file and pay estimated taxes to Maryland.”

• If income not subject to withholding arrives during the year and results in a tax liability of $500 or more, file Form PV or your preprinted voucher and prorate payments over the remaining quarters.

  “If you receive taxable income during the year which is not subject to withholding and which results in a tax liability of $500 or more, you should file Form PV or your preprinted voucher and prorate payments over the remaining quarters.”

Maryland’s tip says four equal installments, paid on time, must total the smaller of two amounts to avoid interest, and each quarterly payment must be at least 25 percent of your required total. The Comptroller’s 2025 Form 502UP words the same exception: no interest if you paid four quarterly payments as required, each at least one-fourth of 110% of last year’s taxes or 90% of the current year’s taxes.

• One amount is 90 percent of the state income tax developed for the current year.

  “90 percent of the state income tax developed for the current year, or”

• The other is 110 percent of the previous year’s state tax liability paid quarterly as required, unless the income is from wagering, awards or prizes.

  “110 percent of the previous year's state tax liability paid quarterly as required, unless the income is from wagering, awards or prizes.”

• Each quarterly payment must be at least 25 percent of your required total.

  “Each quarterly payment must be at least 25 percent of your required total.”

Maryland’s skip rule has an extra condition: the first three quarterly payments must have been filed.

• If you filed the first three quarterly payments and file your final return before January 31st, paying the balance due with it, you would not have to file and pay the fourth quarter payment normally due on January 15th.

  “If you filed the first three quarterly payments and you file your final individual return before January 31st, paying the balance due with that return, then you would not be required to file and pay the fourth quarter declaration payment normally due on January 15th.”

• If a due date falls on a Saturday, Sunday or legal holiday, the voucher is due on the next business day.

  “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.”

Maryland uses Form PV, the Personal Tax Payment Voucher, for estimated payments: box 1 is labeled Estimated Payment/Quarterly (502D). The newest Form PV this page could read is the 2024 edition. To pay by mail, make the check or money order payable to Comptroller of Maryland and send it with the voucher to Comptroller of Maryland, Payment Processing, PO Box 8888, Annapolis, MD 21401-8888.

The tip names the Comptroller’s iFile program for electronic estimated payments, and the Form PV instructions say you may pay electronically at marylandtaxes.gov by selecting Payments under Individual (that note is written for a balance due on a return). Both are older documents, so confirm the current online payment screen on marylandtaxes.gov.

• If you are filing estimated taxes for the first time, you must complete and file Form PV to establish your account.

  “If you are filing estimated taxes for the first time, you must complete and file Form PV to establish your account.”

• On Form PV, if you check box 1 (estimated payment), also check box 1a if you are a first-time estimated filer or your filing status has changed.

  “If Box 1 is checked, also check box 1a., if first time estimated filer or if filing status has changed.”

• The Comptroller’s tip says you may file and pay estimated taxes electronically with its iFile program, including scheduling all of your payments at one time.

  “You may file and pay your estimated taxes electronically using our iFile program.”

Maryland charges interest, not a flat penalty, on underpaid estimated tax, and figures it on Form 502UP, Underpayment of Estimated Income Tax by Individuals. This page does not state an interest rate: the 2025 form lists rates for 2025 periods and the 2026 rates were not read. The form says no interest is due if either exception applies:

• No interest is due if the tax liability on gross income after Maryland withholding is $500 or less, or if you made four quarterly payments as required, each at least one-fourth of 110% of last year’s taxes or 90% of the current year’s taxes.

  “No interest is due and this form should not be filed if: A. The tax liability on gross income after deducting Maryland withholding is $500 or less, or, B. You have made four quarterly payments as required, each equal to or more than one-fourth of either of the following: (1) 110% of last year’s taxes, or (2) 90% of the current year’s taxes.”
