Preparing for Your First POSC Access
- Be an active or recently retired Maryland state government employee paid by the Central Payroll Bureau.
- Have access to your most recent pay stub (within the last 8 weeks) for initial sign-up, which contains your Agency Number and Check/Advice Number.
- Your Social Security Number and Date of Birth for identity verification during sign-up and for account recovery.
- An email address, which will be used for multi-factor authentication (MFA) and account recovery, especially for the new secure PIN system as of March 2026.
- A stable internet connection and a compatible web browser.
Entering the Maryland Payroll Online Service Center
- Navigate to the Central Payroll Bureau Website: Visit the official Comptroller of Maryland website, typically marylandtaxes.gov.
- Locate the POSC Link: Look for the POSC (Payroll Online Service Center) link, usually found on the right side of the screen or within the payroll services section.
- Click "Logon": On the POSC Start Page, select the Logon option to proceed.
- Enter Credentials: Input your established Logon ID and Password into the respective fields.
- Complete Multi-Factor Authentication (MFA): As of March 2026, a secure PIN will be sent to the email address registered with your POSC account. You must enter this PIN to gain access.
Exploring Your Payroll Online Services
- View and Print Pay Stubs: Access up to 12 rolling months of your most recent pay stub information, including year-end summaries. Employees using direct deposit can view an entire current calendar year's history, while those receiving printed checks can view the two most recent.
- Duplicate W-2 Data: View and print duplicate copies of your W-2s for the most recent three reporting years.
- Eliminate Printed Pay Advice: Opt out of receiving physical pay stubs from the Central Payroll Bureau.
- Address Updates: Submit changes to your official payroll address directly online. Note that this typically does not update addresses for benefits, which may require separate forms.
- Direct Deposit Updates: Modify existing direct deposit information, such as bank routing numbers and account numbers. Initial direct deposit setups usually require an original paper form.
- W4 Withholding Updates: Submit updates to your W4 tax withholding information. New employees or those claiming "Exempt" status for federal or state taxes might still need to submit original paper forms.
- Web Only Access: Enable this feature for enhanced access to current and prior year-end pay stub information (up to 5 years of history starting from 2005 for year-end).
Regaining Access to Your Payroll Account
⚠️ Forgot Logon ID or Password
Cause: User cannot recall their login credentials.
Solution: Utilize the Recover LogonID / Reset Forgotten Password process available on the POSC login page. This process uses your Social Security Number and Date of Birth for authentication. An email address is also important for this process.
⚠️ Locked Out of Your Account
Cause: Multiple failed login attempts or system-imposed security lock.
Solution: We know being locked out is stressful. If you are locked out, contact the help desk directly via email at [email protected]. Include your Full Name, Contact Phone Number, and a brief description of the issue.
⚠️ Cannot Sign Up - Missing Pay Stub Information
Cause: Lacking the required Agency Number or Check/Advice Number from a recent pay stub (within the last 8 weeks).
Solution: If you do not have access to your most recent pay stub, contact your agency's payroll representative for assistance.
⚠️ Unable to Receive Secure PIN for MFA
Cause: The email address registered with POSC is incorrect or outdated.
Solution: Ensure your email address within POSC is current, especially since Multi-Factor Authentication (MFA) sending a PIN to your registered email became mandatory in March 2026. You can check your registered email under the "Modify User Logon" menu after logging in, or contact support if you cannot log in at all.
Securing Your Personal Payroll Data
- 🔒 Strong Password Practices: Create a password that is difficult for others to guess. Avoid using easily accessible personal information like your Social Security Number, birthday, or maiden name. Use a mixture of letters and numbers, and do not use common or newsworthy words.
- 🔒 Multi-Factor Authentication (MFA): Be aware that as of March 2026, a secure PIN will be sent to your registered email address for login verification. Keep your email address updated within the portal.
- 🔒 Protect Your Credentials: Never share your Logon ID or Password with anyone. The combination of these credentials provides secure access to your personal payroll data.
- 🔒 Official Website Verification: Always ensure you are on the official Comptroller of Maryland website (marylandtaxes.gov) before entering your login information. Official government websites use the .gov domain and HTTPS for security.
- 🔒 Regularly Review Information: Periodically check your pay stubs, W-2s, and personal information within POSC to ensure accuracy and detect any unauthorized changes.
🎧 Official Support & Help Center
Email for POSC assistance: [email protected]. For inquiries about pay stubs older than 12 months (if your agency cannot help), you can call Central Payroll at 410-260-7401.
Quick Answers for Maryland State Employees
Q: How do I obtain copies of my pay stubs online?
The best way to get your pay stubs is by signing up for and logging into the POSC digital portal. You can view and print your last 12 months of pay stubs, plus previous year-end pay stubs. If you need older pay stubs (beyond 12 months), first contact your agency's payroll department.
Q: Can I update my address through the Maryland POSC portal?
Yes, you can submit updates to your official payroll address directly through POSC. This is the most efficient method for updating your address with Central Payroll. Remember that this might not update your address for benefits, and you may need to update it separately in systems like WORKDAY.
Q: How can I reset my POSC password if I forget it?
If you've forgotten your Logon ID or Password, use the Recover LogonID / Reset Forgotten Password option on the POSC login page. You will need your Social Security Number and Date of Birth to verify your identity. An email address is also critical for this recovery process.
Q: What is Multi-Factor Authentication (MFA) for POSC and when did it start?
Multi-Factor Authentication (MFA) for POSC involves sending a secure PIN to your registered email address when you attempt to log in. This extra security measure began on March 30, 2026, to help protect employee information and payroll data. It's crucial to have a valid email address on file.
Q: Where can I find my W-2 forms in POSC?
Within the POSC portal, you can access and print duplicate copies of your W-2 data for the most recent three reporting years.
