Maryland Estimated Tax Payments: What You Need to Know

Getting your taxes done on time is very important. If you're a taxpayer in Maryland, knowing about estimated tax payments is key in avoiding penalties and interest. Maryland makes some individuals and businesses do quarterly estimated tax payments. This is especially true if you anticipate owing $500 or more in state income taxes after doing your withholdings. This information guide organizes what you need to know about Maryland estimated tax payments, including deadlines, forms, and how to pay.

Does Maryland Require Quarterly Tax Payments?

Yes. Maryland law requires quarterly estimated tax payments for individuals, self-employed professionals, and businesses who expect to owe at least $500 in state income tax after accounting for withholding and credits.

The goal is to ensure taxpayers pay their taxes gradually throughout the year instead of waiting until the annual tax return is filed. Failing to make these payments can result in penalties and interest.

Who typically needs to pay?

• Self-employed individuals
• Small business owners
• Individuals with significant income from investments, rental properties, or side businesses
• Those receiving large bonuses or irregular income without withholding

If your income is fully covered by withholding from your job or pensions, you may not need to make estimated payments.

What Are the Due Dates for Quarterly Estimated Payments?

Maryland’s estimated tax payments are due four times a year, aligning roughly with the federal IRS schedule. The dates for the 2025 tax year are:

‍

Tips:

• If a due date falls on a weekend or holiday, the deadline is typically extended to the next business day.
• Missing a payment can trigger a penalty for underpayment, calculated based on the amount owed and the time overdue.

What Is the Form for Estimated Tax Payments in Maryland?

To make estimated tax payments, Maryland taxpayers generally use Form 502D – Maryland Estimated Income Tax Payment Voucher. This form allows you to report the expected income and calculate the estimated tax due for the quarter.

Key points about Form 502D:

• It’s designed for individuals only. Businesses may have separate forms.
• You must provide your Social Security number or Maryland tax ID on the voucher.
• Form 502D can be filed with a check or electronically, depending on your preference.

For businesses or other entities, Maryland provides separate forms such as Form 500D for corporations.

How Do I Make My Estimated Tax Payments?

Maryland offers several convenient options for paying estimated taxes:

1. Electronic Payment (Recommended)
   
   • Use Maryland’s Comptroller ePay system for a secure, fast, and accurate method.
   • Payments can be made via bank account transfer, credit card, or debit card.
   • You receive instant confirmation, which helps track your payments and avoid late penalties.
2. Mail Payment with Form 502D
   
   • Complete Form 502D with your estimated tax calculation.
   • Attach a check or money order payable to “Comptroller of Maryland”.
   • Mail to the address provided on the form.
3. Through a Tax Professional
   
   • Many taxpayers hire CPAs or tax advisors to calculate and submit estimated payments.
   • Professionals can also help adjust quarterly payments if your income fluctuates during the year.

Pro Tip: Keep a record of each payment to reconcile with your annual tax return. Maryland automatically credits your estimated payments toward your total tax liability when filing your state return.

• Avoids large year-end tax bills
