Introduction
Indiana rarely tops the list when UK entrepreneurs think about US expansion. It should. Low filing costs, a central logistics position, and an LLC formation process that asks nothing about your residency or citizenship make it a practical entry point into the US market.
Here's the catch many founders miss: registering the entity is the easy part. The real complexity sits in what comes after — getting an EIN without a US Social Security Number, opening a business bank account as a non-resident, and keeping both HMRC and the IRS satisfied at the same time.
This guide walks through entity choice, the exact registration steps on Indiana's INBiz portal, the tax and compliance obligations that follow, and where a US visa actually becomes relevant.
Key Takeaways
- UK citizens can form an Indiana LLC or corporation entirely remotely: no US residency or citizenship required
- Indiana charges no franchise tax, with state filing fees among the lowest in the US
- An EIN, US business bank account, and Indiana registered agent are mandatory before you trade
- UK founders face dual reporting duties: US federal/state filings plus HMRC self-assessment on foreign income
- Incorporating remotely doesn't need a visa; physically working in the business does
Why Indiana Is a Strategic Market for UK Entrepreneurs
Indiana's economy generated $545.2 billion in GDP in 2025 (FRED/BEA data), and its cost base undercuts many coastal alternatives. Indianapolis office space averages $22.88 per square foot, roughly half of comparable downtown Chicago rates near $44.29 PSF (Colliers Q4 2025 report).
Geography does a lot of the heavy lifting. Indiana sits on more pass-through interstates than almost any other state and hosts FedEx's second-largest global air hub. Businesses also get one-day truck access to over 80% of the US population, with the Port of Indiana-Burns Harbor sitting just 18 nautical miles from Chicago.
For UK founders specifically, the trade backdrop is strong: total UK-US trade reached £331.7 billion in 2025, representing 17.5% of all UK trade.
Indiana's strongest sectors for UK businesses:
- Advanced manufacturing (over 25% of state GDP)
- Logistics and freight
- Life sciences and agbiosciences (152,000+ workers at that intersection)
- Agri-tech
Formation is practical for remote founders too. Registration runs almost entirely through INBiz, Indiana's online business portal: no in-person filing and no notarised paperwork mailed across the Atlantic.
Choosing the Right Business Structure in Indiana
Indiana gives UK founders three practical paths. Choose based on how you plan to fund the business, how you want profits taxed, and whether you already operate a UK limited company.
Quick fit:
- LLC — most solo or bootstrapped UK founders
- C-Corp — venture capital or multi-investor stock plans
- Foreign qualification — trade in Indiana through your existing UK Ltd
Limited Liability Company (LLC)
The LLC is the default choice for most UK founders. It offers pass-through taxation, so profits flow to the owners' personal returns rather than being taxed at the entity level first.
There's no minimum capital requirement, and a single UK founder can own the entire LLC without a US co-owner.
Corporation (C-Corp)
A C-Corp suits founders planning to raise venture capital or issue stock to multiple investors. The trade-off is double taxation: the corporation pays tax on profits, then shareholders pay tax again on dividends.
If you're bootstrapping or running a lean operation, this structure adds complexity without much upside.
Foreign Qualification / Branch
If you already run a UK limited company, you can register it as a "foreign entity" in Indiana rather than forming a brand-new US company. This uses State Form 56369 through INBiz and lets your existing UK company transact business in Indiana directly.
That route keeps you on one entity instead of two, but you must still maintain an Indiana registered agent at all times.
For most UK founders starting fresh, form an Indiana LLC first unless investor plans or an existing UK Ltd clearly point elsewhere.
How to Register a Business in Indiana from the UK – Step by Step
Follow these steps in order. Skipping ahead (especially the registered agent) will stall your filing.
Check name availability: Log into INBiz, select Online Services, then Name Reservations. Available names can be held for 120 days before you file.
Appoint a registered agent: Every Indiana entity must keep a registered agent with a physical Indiana address. Non-resident owners cannot skip this; it is your legal point of contact for state notices.
File your formation documents: Submit Articles of Organization (LLC) or Articles of Incorporation (Corp) through INBiz. Paper filing is $100; Indiana Code sets a $75 electronic fee for corporations. INBiz gives no guaranteed turnaround, so build in buffer.
Obtain your EIN from the IRS: Non-US applicants hit friction here. Without a Social Security Number, you cannot use the IRS online EIN tool. Instead:
- Complete Form SS-4, entering "foreign" or "N/A" on line 7b
- Apply by phone (267-941-1099), fax, or mail
- Fax processing typically takes about 4 business days; mail can take roughly 4 weeks
Open a US business bank account: Traditional Indiana banks often require an in-person visit, which is impractical for non-residents. Digital-first platforms such as Wise, Mercury, or Relay are the practical option for UK founders running the business remotely.
Register for Indiana state taxes via INTIME: If you sell goods, register to collect Indiana's 7% sales tax. If you hire staff, register for employer withholding once you have your EIN.
UK founders often lose momentum here, juggling IRS fax lines, state tax portals, and bank checks across time zones. VJM Global's US entity formation team handles the state filing, EIN application, and coordination as one engagement rather than six separate tasks.
Tax, Compliance, and Cross-Border Obligations
US and Indiana Tax Rates
Indiana's corporate adjusted gross income tax sits at 4.90%, a rate unchanged since July 2021. Alongside the federal corporate rate of 21% (per IRS Publication 542), Indiana remains competitive against higher-tax states like California or New York.
For UK founders, the recurring obligations usually look like this:
- Pay federal corporate tax at 21% and Indiana AGI tax at 4.90%
- File Indiana’s Business Entity Report every two years
- Apply the UK-US tax treaty correctly (federal only, not state)
- Report foreign income to HMRC and claim double-tax relief
The Biennial Business Entity Report
Every Indiana entity must file a Business Entity Report every two years, due by the end of the month of formation. Filing costs $32 online or $50 by other methods. Miss it, and Indiana moves toward administrative dissolution: a real risk for UK founders who lose track of state deadlines while managing HMRC obligations.
The UK-US Double Taxation Treaty
Article 7 of the UK-US tax treaty prevents your business profits from being taxed twice. Profits are generally taxable only in the state where the enterprise operates, unless you maintain a "permanent establishment" in the other country.
One important caveat: this treaty does not cover state-level income taxes, per IRS guidance, so Indiana's 4.90% state tax sits outside treaty protection.
HMRC Reporting Back Home
As a UK tax resident, you must declare foreign business income to HMRC through Self Assessment, using the SA106 form to claim foreign tax credit relief where US tax has already been paid.
That dual-filing setup—IRS on one side, HMRC on the other—is where cross-border advice matters most. VJM Global's cross-border tax advisory maps US filings to HMRC disclosure so relief is claimed cleanly and nothing is missed between the two systems.
Visa and Physical Presence Considerations for UK Founders
Here's the distinction that trips people up: incorporating and managing an Indiana business remotely from the UK does not require a US visa. You can own 100% of an Indiana LLC, sign contracts, and run payroll without ever setting foot in the country.
Physical presence is different. If you need to work on the ground in the US, these routes matter:
- E-2 Treaty Investor visa — For actively running or investing substantially in the US business on the ground. USCIS requires UK nationality (a qualifying treaty country), a real investment, 50%+ ownership or operational control, and a business that generates more than minimal living support.
- ESTA / Visa Waiver Program — Short business trips of 90 days or less: meetings, scouting locations, contract negotiations. Does not permit employment.
- B-1 visa — Similar to ESTA: consultations, negotiations, conferences. You cannot draw a US salary under B-1 status.
If you manage Indiana operations from London while staff or contractors handle the ground work, none of these visas apply.
Frequently Asked Questions
How much does it cost to start a business in Indiana?
State filing runs $75-$100 depending on entity type and filing method, plus registered agent fees (typically charged separately by your chosen provider). Budget for the biennial $32-$50 Business Entity Report as an ongoing cost.
How can I register a foreign business in Indiana?
If you already have a UK company, file a Foreign Registration Statement (State Form 56369) through INBiz rather than forming a new US entity. You'll still need a continuously maintained Indiana registered agent.
What do I need to start a small business in Indiana?
At minimum you need:
- A registered agent with an Indiana address
- An EIN from the IRS and a US business bank account
- Registration for applicable state taxes (sales tax or employer withholding) through INTIME
Can a UK citizen start a business in Indiana?
Yes. There's no citizenship or residency requirement to form an Indiana LLC or corporation. A visa only becomes necessary if you plan to physically work inside the US, not to incorporate or manage the business remotely.
