How to Pay Your Montgomery County Property Tax
Where and how to pay Montgomery County property tax
Montgomery County property taxes are collected by the Department of Finance, and you can pay online, by mail, in person, or by phone. The online portal at montgomerycountymd.gov is the fastest route — you can pay immediately with a bank account or credit card, and you'll get a confirmation number right away. If you prefer to mail a check, send it to the address printed on your tax bill; allow at least two weeks for it to arrive and post to your account.
You can also pay in person at the Department of Finance office during business hours, or call their payment line to pay by phone with a debit or credit card. Whichever method you choose, have your property account number (printed on your bill) ready. Payments are due by the date shown on your bill — typically in two installments per year, though the exact dates depend on your property class and when the county assesses it.
If you pay online or by phone with a credit card, the county charges a convenience fee on top of your tax amount. Paying by check, in person, or through a bank's bill-pay service avoids this fee. The fee varies depending on the payment processor, so check the website before you submit payment.

What happens if you miss a payment deadline
If your payment does not arrive by the due date shown on your bill, Montgomery County adds a penalty and interest to your account. The penalty is a percentage of the unpaid tax (the exact rate depends on how late the payment is), and interest accrues daily on the unpaid balance. These charges stack, so a late payment grows more expensive the longer it sits.
After a bill remains unpaid for a certain period, the county may place a lien on your property, which means the county has a legal claim against it. A lien does not force you to sell, but it stays on the property record and can complicate a future sale or refinance. The county can also refer the debt to a collection agency or pursue other legal action to recover the money.
If you realize you will miss a deadline, contact the Department of Finance before the due date. They may be able to set up a payment plan that lets you pay in installments rather than all at once, which stops penalties from accruing on the unpaid portion.
Setting up automatic payments or a payment plan
You can arrange for automatic payments through the online portal, which withdraws money from your bank account on a date you choose. This is useful if you want to pay in installments throughout the year rather than waiting for the county's official due dates. Automatic payments reduce the risk of forgetting a deadline, though you are still responsible for making sure the amount is correct and your account has sufficient funds.
If you cannot pay the full amount by the due date and want to avoid penalties, call the Department of Finance to discuss a formal payment plan. The county may allow you to split the debt into smaller monthly payments, though you will typically still owe interest on the unpaid balance. A payment plan must be arranged before the bill becomes delinquent — waiting until after the deadline makes it harder to negotiate.
Understanding your property tax bill
Your Montgomery County property tax bill shows your property account number, the assessed value of your property, the tax rate for your property class, and the total amount due. The bill also lists the due date and any penalties or interest from previous unpaid bills. If you do not recognize a charge or believe the assessed value is wrong, you can dispute it through a separate process (the assessment appeals process), but you should still pay the bill by the due date to avoid penalties while your dispute is being reviewed.
Property tax bills are mailed to the address on file with the county. If you move or change your mailing address, update it with the Department of Finance so you do not miss a bill. You can also sign up for email notifications through the online portal, which alerts you when a new bill is ready or a payment is due.
Checking your payment history and account balance
You can look up your property tax account online using your property address or account number. The county's website shows your current balance, payment history, and any penalties or interest owed. This is useful if you want to verify that a payment you mailed has posted, or if you need to know exactly how much you owe before making a payment.
If you notice a payment is missing from your history or a charge you do not recognize, contact the Department of Finance with your account number and the date you made the payment. If you paid by check, have the check number ready. The department can research the payment and correct the record if there was an error.

Frequently Asked Questions
What if I pay my property tax late but before the lien is filed?
You will owe the penalty and interest that accrued during the late period, but paying before a lien is filed stops the county from taking further collection action. The exact penalty depends on how many days late the payment is. Contact the Department of Finance to confirm the total amount owed, including penalties and interest, before you submit payment.
Can I pay my property tax with a credit card without a convenience fee?
No. The online portal charges a convenience fee when you use a credit card. You can avoid the fee by paying with a bank account through the online portal, by mailing a check, by paying in person, or by using your bank's bill-pay service. The fee amount varies, so check the website before you choose your payment method.
What if I disagree with the assessed value on my tax bill?
You can file an appeal with the county's assessment office, usually within a set time frame after your bill is issued. The appeal process is separate from paying your bill — you should still pay by the due date to avoid penalties while your appeal is being reviewed. Information about filing an appeal is available on the Department of Finance website or by calling the assessment office.
Do I need to pay property tax if I rent instead of own?
No. Renters do not pay property tax directly. The property owner pays the tax, and the cost is typically factored into the rent. If you are a renter and receive a property tax bill, contact the Department of Finance to verify that the property is registered to the correct owner.
How do I know if my property qualifies for a tax relief program?
Each program has different income limits, age requirements, and other may be able to access rules. The Department of Finance website lists all available programs and their requirements. You can also call their office to discuss your situation and learn which programs you may be able to apply for. Applications are usually due by a specific date each year.
