Who should pay estimated taxes?

If you are self-employed or receive income from a pension, capital gains, lottery or another source for which no Maryland tax (or not enough Maryland tax) is withheld, you can make quarterly estimated tax payments as part of a pay-as-you-go plan, using Form 502D or pre-printed vouchers supplied by us after you establish an estimated tax account.

If your employer does not withhold enough Maryland taxes from your pay, you may still be required to make quarterly estimated income tax payments if you develop a tax liability that exceeds the amount withheld by your employer by more than $500.
