Maryland Unfiled Payroll Tax Returns Checklist
Introduction
Maryland employers must withhold state income taxes and file payroll tax returns in accordance with schedules set by the Comptroller of Maryland. When returns remain unfiled, the state begins formal collection procedures that can result in interest and penalties, tax liabilities, and enforcement actions.
Unfiled tax returns create compliance gaps that trigger escalating contact from the state and growing financial liability. This checklist explains the administrative process and provides steps to resolve unfiled payroll tax returns effectively, covering both state and federal employment taxes.
What This Issue Means
An unfiled payroll tax return occurs when an employer fails to submit required state payroll tax documentation by the deadline established by the Comptroller of Maryland. Employers typically file quarterly or monthly returns, depending on their withholding amounts: quarterly filers owe less than $700 per quarter, and monthly filers owe $700 or more.
This differs from late payment, because a return can remain unfiled even if the employer paid some or all of the taxes owed. When returns stay unfiled, the state lacks official records of wages paid, employees covered, and withholding taxes collected for Social Security and Medicare tax purposes.
Why the State Requires This
Maryland requires payroll tax returns to maintain accurate records of wages paid and taxes withheld from employees working in Maryland. These returns allow the Comptroller's Office to verify that employers withhold correct amounts for state income taxes and local income taxes, that employees receive proper credit for taxes paid, and that the state can track tax revenue for budgeting purposes.
When returns go unfiled, the state cannot perform verification functions or maintain documentation needed for accounting records. The Comptroller's Office contacts employers when filings become significantly overdue and escalates to formal collection procedures if employers do not respond.
What Happens If This Is Ignored
When unfiled returns remain unaddressed, the Comptroller's Office sends written notices to the employer's last known address requesting immediate filing and tax payment. If the employer does not respond, the state escalates collection efforts through additional notices, referrals to collection agencies, and potential liens against business property or levies against bank accounts to recover delinquent taxes.
The state may assess estimated tax amounts if the employer does not provide actual return information, as the Internal Revenue Service does with substitute return assessments. Under Maryland Tax-General Code Section 13-707, the Comptroller may suspend or revoke business licenses for willful failure to withhold or pay income tax.
What This Does Not Mean
An unfiled return notice does not mean the business faces criminal charges or criminal prosecution for tax evasion immediately. It does not mean the state has frozen all business accounts or seized assets, as those actions follow specific legal procedures.
An unfiled return does not automatically establish the correct tax liability because the state needs the actual return to calculate the final liability. This issue does not indicate that employees' state income tax credits have been permanently denied, though delays in proper wage reporting may occur until returns are filed and processed.
Understanding Related Federal Requirements
Employers with unfiled Maryland payroll tax returns often have corresponding federal employment tax obligations that require attention. Federal forms include Form 941 (Employer's Quarterly Federal Tax Return) for quarterly federal tax liability reporting, Form 940 for federal unemployment taxes, and Form W-2 for annual wage statements.
The Internal Revenue Service requires these employment tax reporting forms to be filed on specific schedules, and failure to file can result in trust fund recovery penalty assessments against responsible parties. Employers should verify that both state and federal tax return filing requirements are up to date to avoid compounding tax issues.
Step-by-Step Checklist
Step 1: Gather Payroll Records
Collect all payroll documentation for the unfiled periods, including wage records, withholding amounts, employment taxes withheld, and quarterly or monthly payroll summaries organized by pay period or filing period.
Step 2: Identify Unfiled Periods
Review notices from the Comptroller's Office or your filing records to determine exactly which quarters or months remain unfiled and verify which specific delinquent returns are missing.
Step 3: Calculate Payroll Information
Use gathered payroll records to calculate or reconstruct wages paid, employees covered, and withholding taxes collected for each unfiled period while documenting any estimation methods if exact figures cannot be determined.
Step 4: Contact the Comptroller's Office
Reach out to the Comptroller of Maryland at 1-800-638-2937 or 410-260-7980 to discuss unfiled returns and request information about procedures for filing past due tax returns and required forms.
Step 5: Obtain Current Filing Instructions
Request the specific forms needed, confirm whether returns can be filed electronically through Maryland Tax Connect or require paper returns, and verify all mailing addresses or online submission portals.
Step 6: Complete Required Forms
Use reconstructed payroll information to complete Form MW506 or appropriate Maryland payroll tax return forms for unfiled periods, ensuring all required information, including employee details and taxes withheld, is accurate.
Step 7: Prepare Cover Letter
Write a brief letter, including the business name, Central Registration Number, and contact information, that explains why returns were not filed previously and specifies which periods are being submitted.
Step 8: Copy All Documents
Make complete copies of all returns and supporting documentation before submission, label the copies with the submission date, and store them securely for your business records and potential audit reconsideration.
Step 9: Submit Returns
Submit completed returns and cover letter according to Comptroller's Office instructions using the specified delivery method, and keep receipts and tracking information if mailing via certified mail.
Step 10: Document Submission
Create a submission record that includes the date, method, tracking or confirmation number, and what was submitted, along with the names of any state employees contacted during the filing process.
Step 11: Monitor State Correspondence
Watch for acknowledgment correspondence and follow-up notices after submission, noting that processing times vary depending on the completeness of the return, and do not assume resolution until receiving official acknowledgment.
Step 12: Address Payment Obligations
Determine total amounts owed if the state assesses taxes, penalties, and interest, then contact the Comptroller's Office about payment plans or installment agreements if full payment cannot be made immediately.
Step 13: Consider Professional Assistance
Evaluate whether tax attorneys or experienced tax professionals are needed if the tax issue involves multiple unfiled periods, substantial unpaid taxes, or potential personal liability under trust fund taxes provisions.
Common Mistakes to Avoid
• Ignoring Initial Notices: Many employers delay responding to unfiled return notices, hoping the issue resolves itself, which typically results in escalated collection efforts and additional penalties. The Comptroller's Office maintains detailed correspondence records that strengthen enforcement actions when employers fail to comply with requirements.
• Submitting Incomplete Returns: Filing returns with missing information, calculation errors, or incorrect employee data triggers state requests for corrections that delay resolution and may result in additional notices. Double-check all figures and ensure all required fields are completed before submission to avoid becoming a non-criminal non-filer and incurring mounting service charges.
• Missing Follow-Up Deadlines: The state may request additional documentation or information to process the return, and these requests typically include deadlines. Missing response deadlines can result in the state using estimated figures or proceeding with enforcement actions in place of the return process.
• Assuming Penalty Elimination: Late-filing penalties apply when returns are not filed by the original due dates, even if the employer eventually files them. The state generally applies applicable penalties automatically unless the taxpayer requests formal penalty abatement through a separate process demonstrating reasonable cause.
• Neglecting Federal Requirements: Focusing only on Maryland taxes while ignoring corresponding federal employment taxes creates additional compliance problems with the Internal Revenue Service. Employers should verify that Form 941, Form 940, and Form W-2 filings are current to address all employment tax liabilities comprehensively.

Frequently Asked Questions
Can I File Returns Myself, or Do I Need a Professional?
Employers can file returns themselves using the state forms and instructions provided by the Comptroller of Maryland. However, reconstructing payroll information for multiple past due tax returns can be complex, so many employers choose to work with tax preparers, payroll companies, or tax attorneys for legal services. The Comptroller's Office cannot provide tax advice but can answer procedural questions about filing requirements and submission methods for compliance programs.
Will Filing Resolve All Penalties and Interest?
Filing unfiled returns resolves the compliance issue, but interest and penalties will still be calculated and assessed based on original due dates. Late filing penalties typically apply when returns were originally due, regardless of when they are filed, and interest accrues on unpaid taxes from the original due dates. Maryland withholding penalty assessments remain in effect unless the employer requests penalty abatement and demonstrates reasonable cause to the Comptroller's Office through proper appeal procedures.
Can Responsible Individuals Be Held Personally Liable?
Maryland law imposes personal and individual liability on any employer or payer who negligently fails to withhold required tax or pay it to the Comptroller. If the employer is a corporation, personal liability extends to the officer or agent who is responsible for withholding and transmitting the tax under the trust fund recovery penalty provisions. This is statutory liability under the Maryland Tax-General Article that applies when individuals are responsible for payroll tax compliance and can result in a personal assessment for back taxes owed.
How Do State and Federal Tax Issues Interact?
Employers with unfiled Maryland payroll tax returns often have corresponding federal tax return issues that require coordinated resolution strategies. The Internal Revenue Service and Maryland Comptroller's Office operate independently but share employment tax information that can trigger audits or enforcement in both jurisdictions. Addressing both state and federal employment taxes simultaneously through comprehensive compliance programs prevents compounding penalties and demonstrates a good faith effort to resolve all outstanding tax liabilities with both authorities.
