Estimated Tax

If you are self-employed or do not have Maryland income taxes withheld by an employer, you can make quarterly estimated tax payments as part of a pay-as-you-go plan, using Form 502D or pre-printed vouchers.

If your employer does withhold 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.

If you receive $500 or more in income from awards, prizes, lotteries, racetracks or raffles, you must file Form 502D - along with your full estimated tax payment - within 60 days of receiving the income.
