Maryland LLC Tax Guide for Non-Resident Entrepreneurs

Everything you need to know about forming and maintaining an LLC in Maryland, including state taxes, formation costs, annual requirements, and federal compliance obligations.

Why Choose Maryland for Your LLC?

Proximity to Washington D.C. and federal government agencies, strong cybersecurity sector, access to top research institutions (Johns Hopkins, NIH), and a well-educated workforce.

Maryland Tax Overview

Understanding Maryland's tax structure is essential for non-resident LLC owners. Here's a comprehensive breakdown of all applicable taxes.

Tax TypeRateApplies to LLCs?
Personal Income Tax2% – 5.75%Yes, on MD-sourced income
Corporate/Entity Tax8.25%C-corps and entities with nexus
Sales Tax6%If selling taxable goods/services
Annual Fee$300 annual report + personal property returnYes

Personal Income Tax

Maryland imposes a personal income tax at rates of 2% – 5.75%. If your LLC is taxed as a disregarded entity or partnership, your share of the LLC's Maryland-sourced income may be subject to state income tax. Non-residents are generally only taxed on income sourced within Maryland.

If your LLC has no physical presence, employees, or customers in Maryland, you likely won't owe state income tax — but you should confirm this with a tax professional familiar with Maryland nexus rules.

Corporate / Entity Tax

Maryland imposes a corporate tax rate of 8.25%. This applies to LLCs that have elected to be taxed as C-corporations. Single-member LLCs treated as disregarded entities for federal tax purposes are generally not subject to the state corporate income tax.

Sales Tax

Maryland has a state sales tax rate of 6%. Local jurisdictions may impose additional sales taxes. If your LLC sells taxable goods or services in Maryland, you'll need to collect and remit sales tax. Remote sellers may be required to collect Maryland sales tax if they exceed the state's economic nexus thresholds (typically $100,000 in sales or 200 transactions).

LLC Formation Requirements

Forming an LLC in Maryland involves the following steps and costs:

  • Formation fee: $100
  • File with: Maryland State Department of Assessments and Taxation
  • Registered agent: Required (must have a physical address in Maryland)
  • Operating agreement: Recommended but not always required to be filed with the state
  • EIN application: Required for tax filing (Form SS-4)

Formation Tip for Non-Residents

As a non-resident entrepreneur, you'll need a registered agent service in Maryland to receive legal and tax documents on your behalf. Registered agent services typically cost $50–$300 per year. You don't need to live in or visit Maryland to form or maintain an LLC there.

Annual Requirements & Fees

After forming your Maryland LLC, you'll need to maintain compliance with these ongoing requirements:

RequirementDetails
Annual/Biennial ReportDue April 15
Annual Fee$300 annual report + personal property return
Registered AgentMust maintain continuously
State Tax FilingMay be required if MD-sourced income

Important Note

Maryland requires LLCs to file a Personal Property Return along with the annual report. The state also has local income taxes imposed by counties, adding 2.25%–3.2% on top of the state rate. The combined state and local income tax burden can be significant.

Federal Tax Obligations

Regardless of which state your LLC is formed in, non-resident LLC owners must comply with these federal requirements:

  • Form 5472: Required for all foreign-owned single-member LLCs to report transactions between the LLC and its foreign owner. Penalty for non-filing: $25,000.
  • Pro Forma Form 1120: Filed together with Form 5472 as an information return for disregarded entities.
  • ITIN (Form W-7): Non-residents need an Individual Taxpayer Identification Number to file US tax returns.
  • EIN (Form SS-4): Required for all LLCs to open bank accounts and file taxes.
  • FBAR (FinCEN 114): Required if your US financial accounts exceed $10,000 at any point during the year.

Key Federal Deadlines

Form 5472 + 1120: Due April 15 (6-month extension available to October 15)

FBAR: Due April 15 (automatic extension to October 15)
