Annual Tax Filing for Maryland LLC Owners: The Complete 2026 Guide

Maryland has one of the most robust economies along the Eastern Seaboard, due in large part to an educated workforce, accessible regulatory policies, proximity to the capital, and proximity to the capital. These are all major benefits of operating a Maryland LLC.

Of course, once the LLC is formed, there are many compliance issues that the LLC owner needs to understand to avoid penalties, including:

  • Annual state filing compliance
  • Other tax compliance
  • Federal obligations
  • Ongoing compliance

This guide covers every Maryland LLC owner’s annual tax liabilities, including:

  • Pass-through taxation
  • Franchise tax
  • Personal taxation obligations
  • Non-residents’ requirements when operating an LLC in Maryland

1. Overview of Taxation for a Maryland LLC

Importantly, Maryland LLCs are considered to be pass-through entities. This means:

  • An LLC does not, as a business entity, pay income tax;
  • Any profits are distributed to the members (owners); and.
  • Each owner is then responsible for tax payments on their portion of the income, which is ultimately reported as part of their personal income tax filings (or corporate filings, if applicable).

Unlike most other states, Maryland has the following requirements:

✅ Each LLC must submit an Annual Report

✅ Each LLC must submit a Personal Property Tax Return (if applicable)

✅ Each member must file a State Income Tax Return (if they live in Maryland or have MD-sourced income)

✅ Each member must submit Federal Tax Returns

✅ Employer filings (if applicable)

Maryland LLC requirements must be complied with by all U.S. residents and foreign business owners to avoid penalties and/or loss of good standing and avoid administrative dissolution.

2. Annual Report in Maryland (All LLCs must file)

If your LLC possesses, leases, or utilizes personal property in Maryland — like:

  • Tools
  • Inventory

— you must submit a Personal Property Tax Return along with the Annual Report.

4. Maryland State Income Tax for LLC Members

Since LLCs have a pass-through tax structure, owners’ personal tax compliance depends on their state of residence.

a) Maryland Residents (U.S. citizens or residents)

If you reside in Maryland, you have to file state income tax on all income earned through the LLC, regardless of whether it was earned in Maryland.

b) Non-Residents (Living in another U.S. state)

You must file a Maryland non-resident income tax return for Maryland-sourced income only.

c) International (Non-U.S. Residents)

If you are an international founder operating a Maryland LLC from another country:

  • Your LLC’s income will likely be considered foreign-sourced, meaning you won’t have to pay any Maryland personal income tax, provided the LLC does not have any office, employees, or physical presence in the U.S.
  • If your LLC does have Maryland-sourced income (customers, operations, warehouse, etc.), you must file Maryland non-resident tax returns.

Maryland Individual Tax Forms:

  • Form 502 (resident)
  • Form 505 (non-resident)
  • Pass-through entity K-1 documents

5. Maryland Pass-Through Entity Tax (PTE Tax)

Maryland allows LLCs to elect to pay Pass-Through Entity (PTE) Tax on behalf of their members.

This can help members claim a credit on their personal tax returns and reduce the impact of the federal SALT cap limitation.

PTE Tax Is Useful If:

  • The LLC has high income
  • Members want the LLC to pay the tax instead of paying individually
  • Members want to maximize deductible tax payments

Filing Requirements:

  • Form 510
  • Form 511 (PTE tax return, if applicable)
