Most UK founders researching this topic have the same four questions: Do I need to live in Maryland? Should I form an LLC or a corporation? How do I actually get paid in US dollars? And what happens on the UK side once the money starts moving? This guide walks through planning, entity selection, the Maryland filing sequence, cross-border tax and banking, and the costs you should budget for before you file anything.
This article is general information, not legal or tax advice. Maryland fees, IRS procedures, and UK-US treaty positions change, so confirm current details with a licensed attorney and a cross-border tax adviser before you form or trade.
Key Takeaways
- UK founders can form a Maryland LLC or corporation without US residency; formation is separate from immigration status.
- Core path: validate the idea, pick an entity, appoint a Maryland registered agent, file with SDAT, get an EIN, register taxes, open a business account.
- Budget beyond the filing fee for agent renewals, advice, insurance, banking, and annual Maryland reports.
- A Maryland entity does not grant US live or work rights; review UK-US tax treatment before you trade.
Planning Your Maryland Business Before Formation
Before you file anything, define what the US business will actually do. Are you selling software subscriptions to American customers, running an e-commerce operation, or opening a physical location with staff? The answer changes almost every decision that follows.
Map out:
- Customers and revenue flow: who pays you, in what currency, and how often
- People: employees, contractors, or just yourself
- Premises: a home office, coworking space, warehouse, or none at all
- Structure: subsidiary of your UK company, standalone US business, or branch-style operation reporting back to the UK
Choosing Between Sole Proprietorship, LLC, and Corporation
| Structure | Liability | Typical use for UK founders |
|---|---|---|
| Sole proprietorship | No legal separation from the owner | Rarely suitable once real US contracts or risk are involved |
| LLC | Liability wrapper; flexible ownership | Common default; single-member LLCs are disregarded for federal tax by default, multi-member LLCs default to partnership treatment |
| Corporation | Liability wrapper; stock-based ownership | Useful for fundraising or a UK parent-subsidiary structure; nonresident aliens can't hold S-corp stock, so C-corporation is the default for UK owners |
A Maryland corporation's taxable income is taxed at a flat 8.25% state rate, separate from federal corporate tax. That's worth knowing before you assume an LLC is automatically cheaper; it depends on your profit distribution plans.
Naming and Protecting the Business
Search the Maryland Business Entity Search to confirm your chosen name is distinguishable from existing filings. That check does not clear trademark rights, though. Search the UK Intellectual Property Office register and the USPTO trademark database separately, and check domain availability, before you commit to a brand across both markets.
Finally, sketch a short financial model: startup costs, working capital, currency conversion losses, contractor or payroll costs, insurance, professional fees, and expected Maryland and federal tax. This is the step founders skip most often, and the one that saves the most stress later.
How to Start a Business in Maryland from the UK: Step-by-Step
Once you've decided on the entity and structure, the formation process itself is a fairly linear sequence.
Prepare governance documents. For an LLC, that's Articles of Organization and an operating agreement. For a corporation, it's Articles of Incorporation and bylaws. If your Maryland entity sits under a UK parent, document that ownership relationship clearly from day one. It matters later for tax and banking.
Appoint a Maryland resident agent. Maryland requires a resident agent with a physical Maryland street address (not a PO box) who can accept official notices and service of process during business hours. As a UK founder without a Maryland address, you'll almost certainly need a professional resident-agent service rather than trying to use a friend or acquaintance.
File your formation document with SDAT. Submit through Maryland Business Express to the State Department of Assessments and Taxation. Standard processing can run up to six weeks; online filings usually clear in about seven business days. Confirm current expedited and same-day fees on SDAT's site before you set a launch date.
Apply for an EIN from the IRS. You do not need a US Social Security number. The IRS SS-4 instructions allow "foreign" or "N/A" where the responsible party (the person who ultimately owns or controls the entity) isn't eligible for an SSN or ITIN. Fax applications typically process in about four business days; mailed applications can take roughly four weeks.
Register for Maryland tax accounts. Use the Comptroller's Combined Registration Application. You'll need a sales and use tax licence if you sell taxable goods in Maryland, and an employer withholding account if you pay wages to anyone, including nonresident employees. Don't register for accounts your activity doesn't require. Base this on what the business actually does, not on entity type alone.
Set up post-formation operations. Open a dedicated US business bank account, establish bookkeeping separate from personal or UK-company funds, document any capital contributions or intercompany payments, and arrange appropriate business insurance. Keep every formation and tax record — you'll need them for the annual report and for any future bank or IRS query.
UK-Specific Tax, Banking, and Compliance Considerations
This is the section most guides gloss over, and it's where UK founders run into the most expensive surprises.
Formation Isn't Residence, and It Isn't Immigration Status
Forming a Maryland LLC or corporation does not give you the right to live or work in the United States. Company formation and immigration status are entirely separate legal questions. Plan any physical relocation or work authorisation through the correct immigration channel, not through business registration.
Federal and Maryland Tax Classification Gets Complicated Fast
Your LLC's default federal tax treatment depends on ownership structure:
- Single-member LLC: disregarded by default
- Multi-member LLC: partnership treatment by default
- Optional election: corporate treatment via Form 8832
Here's the trap: a foreign-owned, single-member disregarded LLC is still treated as a corporation for information-reporting purposes under section 6038A.
If there's a reportable transaction with a related party (for example, a management fee paid to your UK company), you'll likely need to file Form 5472 alongside a pro forma Form 1120, even though the entity itself has no standard income tax return obligation. This catches out founders who assume "disregarded" means "no filing required."
What Happens Back in the UK
Setting up in Maryland doesn't pause your UK obligations. Depending on your structure, you may need to consider:
- UK Self Assessment reporting for foreign income, using the foreign section of your return
- HMRC's Controlled Foreign Company rules, which can apply where a UK-resident-controlled company sits outside the UK
- Dividend withholding under the US-UK tax treaty, which caps US source-state tax on qualifying dividends
- Transfer-pricing documentation if related-party transactions flow between your UK and US entities
None of this is a DIY exercise. Get coordinated UK-US advice before money starts moving between the two entities.
The 183-Day Question, Answered Properly
The IRS substantial presence test is genuinely misunderstood. It is not a flat 183-day count. Days are weighted across three years: all current-year days, one-third of the prior year's days, and one-sixth of the year before that, and you need at least 31 days in the current year for the test to apply at all.
That test determines an individual's US tax residency status. It says nothing about whether your Maryland entity owes tax, needs to file Form 5472, or has to submit an annual report. Staying under 183 days does not erase your entity's compliance calendar.
Banking as a UK-Owned Maryland Business
Opening a US business account is its own gate, separate from SDAT approving your filing. Under FinCEN's Customer Due Diligence rule, banks must collect and verify identifying information for every individual owning 25% or more of the entity, plus one control person. A passport typically suffices for a foreign owner.
Come prepared with:
- Passports for all relevant owners
- Formation documents and your EIN letter
- A clear, specific description of the business activity
- Ownership structure documentation, especially if a UK entity holds shares
Keep personal, UK-company, and Maryland-company funds strictly separate from account opening onward, and reconcile foreign-exchange movements as they occur rather than at year-end.
VJM Global coordinates cross-border accounting, tax compliance, and financial reporting for UK businesses with US operations. It is not Maryland legal counsel and does not maintain a Maryland office, but it can help keep UK and US accounting and reporting aligned as money and filings move between the two.
Licences, Costs, and Preparing to Launch
Building a Realistic Cost Checklist
Don't anchor on a single "cost to start a Maryland business" figure. The filing fee is one line among many.
| Cost category | What it covers |
|---|---|
| SDAT formation filing | Certificate of Organization (LLC) or Articles of Incorporation (corporation) |
| Optional expedited processing | Faster turnaround at an added fee |
| Registered agent | Annual renewal for your Maryland address and service-of-process handling |
| EIN assistance | Optional if you use a professional rather than filing directly with the IRS |
| Legal and tax advice | One-off setup review plus ongoing coordination |
| Business insurance | Varies heavily by industry and coverage limits |
| Banking and accounting | Account fees, bookkeeping software, or outsourced bookkeeping |
| Annual Maryland filings | Recurring annual report and any personal property return |
Verify the live SDAT fee schedule before paying anything — figures change, and the difference between standard and same-day processing can be substantial.
Licences Depend on Activity, Not Entity Type
Maryland Business Express is clear that most businesses need some form of licence or permit, but requirements vary by industry and location. Check:
- Professional licensing (if you're in a regulated field)
- Sales-tax registration for retail activity
- Food, health, or safety permits where relevant
- Employment-related registrations if you're hiring
- County or municipal rules specific to where you operate
An online-only business isn't automatically licence-free. Confirm this against your actual activity, not assumptions.
Staying in Good Standing
Maryland requires an annual report (Form 1) with a filing deadline and fee, plus a personal property return where applicable. Other obligations run on their own calendars:
- Registered-agent renewals
- Payroll filings
- Sales-tax returns
Missing these quietly erodes your entity's good standing, which can complicate banking, contracts, and future financing.
Launch Checklist
- Confirm ownership documents and any UK-parent agreements are signed and filed
- Set up bookkeeping before your first transaction, not after
- Decide on payroll versus contractor arrangements
- Secure appropriate business insurance
- Build a US-facing website and payment process
- Schedule recurring compliance reminders for Maryland and IRS deadlines
Consult a US business attorney and a tax adviser experienced with non-US owners before you file. That step matters especially if you'll hire staff, hold premises, sell taxable goods, or run the Maryland entity alongside an existing UK company.
Frequently Asked Questions
How much does it cost to start a business in Maryland?
Maryland formation fees are one-off SDAT filing charges and only part of your budget. Plan also for registered agent renewals, professional advice, banking, insurance, and annual Maryland reports. Check current SDAT fee schedules before you finalise figures, as charges change.
What is the 183-day rule in Maryland and how does it work?
The 183-day rule is a federal, weighted test for an individual's US tax residency, not a test for whether your Maryland company owes tax. Your entity's filing obligations continue regardless of how many days you personally spend in the US.
What is the best business to start in Maryland?
It depends on demand, your skills, available capital, competition, and regulatory requirements in your sector. Research Maryland's industries and validate the idea with real customers before you file formation documents.
Can a UK citizen start a business in Maryland?
Yes. Non-US citizens can generally form a Maryland LLC or corporation, subject to standard requirements around a registered agent, EIN application, banking, and tax registration. Immigration status is a separate legal matter entirely.
Do I need to move to the US to form a Maryland business?
No. You do not need to relocate to file formation documents. You will need a Maryland registered agent, a plan for banking and management from the UK, and separate immigration arrangements if you ever intend to work on US soil.
