US Company Formation from Brunei (2026): No Personal Income Tax, Shariah-Compliant Structuring, US LLC or C-Corp and No US Treaty

Brunei is one of the few countries in the world with no personal income tax. Companies pay 18.5% on profits from Brunei, but individuals pay nothing on salaries, business income, dividends or capital gains. For a Bruneian who owns a US company, that changes the planning: whatever tax the USA charges is usually the only tax, with nothing at home to credit it against.

Brunei is also a Malay Islamic Monarchy where many people and businesses want their affairs to be Shariah-compliant. That affects how a US company is funded and how its money is held. And under its Wawasan Brunei 2035 vision, the government is pushing SMEs and exporters, especially in halal food, to sell beyond Brunei and ASEAN. This guide brings those three points together and compares US LLC formation with US C-Corp formation for Bruneian owners.

In short: Bruneians and Brunei residents can own 100% of a US LLC or C-Corporation, formed remotely. Brunei has no personal income tax, and corporate income tax is 18.5% on Brunei-source income. Brunei withholds 2.5% on interest and 10% on royalties paid to non-residents. There is no US–Brunei treaty, so US corporate dividends carry 30% withholding with no Brunei credit to offset it. A single-member LLC with no US operations usually pays no US income tax at all. A US company can be funded and run in a Shariah-compliant way, mainly through equity rather than interest-bearing loans. With UCB, a Wyoming LLC with EIN is $249 and a Delaware corporation with EIN is $358, all-in.

How Brunei's tax system affects a US company

• Individuals: no tax on income of any kind, including dividends from a US corporation or profits of a US LLC.
• Companies: corporate income tax at 18.5% on income accrued in, derived from or received in Brunei, with relief for small companies and pioneer status incentives.
• Withholding on payments to non-residents: 2.5% on interest and 10% on royalties and some technical fees, when paid by a Brunei payer to a non-resident such as a US company.
• No exchange control. The Brunei dollar is interchangeable with the Singapore dollar at par, and money moves freely.

This produces three rules of thumb:

1. For a Bruneian individual, every dollar of US tax is a final cost. It cannot be credited at home.
2. For a Brunei company, US profits may still be taxed in Brunei if they are received in Brunei, with credit rules that depend on the case. Ask your tax agent before routing US profits to a Brunei company.
3. US dividends are expensive. A US corporation's after-tax profit paid to a Bruneian loses another 30%.

Shariah-compliant structuring

Nothing in US company law conflicts with Islamic finance, but a few choices make a US company easier to run in a Shariah-compliant way.

• Fund the company with equity, not loans. Capital contributions to an LLC or share subscriptions in a corporation are fine. An interest-bearing loan from the owner, or from a conventional US bank, is not. If the company needs finance, it can use profit-sharing arrangements (musharakah or mudarabah) with investors, or US Islamic finance providers for property.
• Choose a non-interest-bearing business account. Most US business checking accounts pay no interest by default. Decline interest-bearing sweeps and savings products, or give any interest earned to charity.
• Pick halal activities. US banks do not ask, but your own standards will. Keep the operating agreement or bylaws consistent with them. An LLC operating agreement can include a clause restricting the business to Shariah-compliant activities.
• Zakat is calculated on the owner's wealth, including the value of the US company. Keep the company's accounts current so the value can be worked out each year.

A US LLC's flexible operating agreement makes it easier to write profit-sharing and Shariah-compliance clauses than in a corporation's standard bylaws.

No US–Brunei treaty

The USA and Brunei have no income tax treaty. US domestic withholding applies:

• 30% on dividends from a US corporation;
• 30% on royalties;
• 30% on related-party interest.

US LLC formation from Brunei

US tax position

The IRS disregards a single-member LLC with a non-resident owner and treats its income as the owner's. If the owner runs the business from Brunei, and the LLC has no US office, employees or dependent agents, its income is generally not connected with a US trade or business and is not taxed in the USA (see effectively connected income explained). With no personal income tax in Brunei either, profits are untaxed in both countries, legitimately, as long as the facts stay that way. The LLC files Form 5472 with a pro forma Form 1120 every year, and the penalty for missing it is $25,000 (see Form 5472 explained).

Example: an online modest-fashion brand

These are illustrative figures, not a client case, at B$1.30 to the dollar.

Nurul runs a modest-fashion label from Bandar Seri Begawan. Her designs are made by a partner factory in Malaysia and sold online, and her fastest-growing market is the USA. She forms a Wyoming LLC with a US business account, takes card payments through a US processor, and uses a US third-party logistics warehouse that ships orders. Annual US sales are US$150,000.

• USA: the warehouse is an independent contractor, and Nurul manages everything from Brunei, so the sales are generally not US business income. She must collect state sales tax in states where her sales exceed economic nexus thresholds (see state taxes for a foreign-owned LLC). The LLC files Form 5472 and a pro forma 1120.
• Brunei: no personal income tax on her share of the profit.
• Shariah: the LLC is funded by her own capital, holds no interest-bearing balances, and her operating agreement limits its activities.

If she later hires a US employee or rents a US showroom, the LLC's profits become US business income, taxed at US individual rates. At that point she should move the US operation into a corporation.

US C-Corp formation from Brunei

US tax position

A US corporation pays 21% federal tax on its profits plus state tax, and files Form 1120 and Form 5472 every year (see the 21% corporate tax explained and the C-Corp guide for non-residents). Dividends to Brunei are withheld at 30%, with nothing to credit it against at home.

Example: a halal food exporter's US importer

Take an illustrative case: a Brunei food company that makes halal-certified sauces and ready meals under the Brunei Halal brand wants to sell to US Muslim grocery chains and online. It forms a Delaware corporation as its US importer.

• The US corporation registers with the FDA, holds stock in a US warehouse, employs a sales manager in New Jersey and sells to retailers. Its US profits are taxed at 21% plus state tax.
• The Brunei company sells the products to the US corporation at arm's-length prices. Its profit is taxed at 18.5% in Brunei.
• Profits are reinvested in US growth rather than paid as dividends, which would lose 30%.
• Funding comes from share capital, not interest-bearing intercompany loans, both for Shariah reasons and because Brunei interest withholding and US interest deduction limits make loans less attractive anyway.

See US subsidiary for a foreign company.

Other cases

• Start-ups raising investment, which need a Delaware C-Corporation (see raising US investment as a foreign founder).
• Long-term US property portfolios held in a corporation that reinvests its rental income.

US property

Some Bruneian families invest in US property, often for children studying in the USA. Rental income is US-source and taxed in the USA. An owner usually elects to be taxed on net rent after expenses and depreciation, and files a US non-resident return each year. Shariah-compliant home financing is available in the USA from specialist providers, which use ijara and musharakah structures. See real estate investment LLC for foreigners.

Which state

• Wyoming or New Mexico for an online or services LLC run from Brunei.
• Delaware for a corporation, an importer or a start-up.
• The state where US staff or a warehouse will be.

See best state for non-residents and the state selector.

What it costs

UCB's prices include state fees and the first year of registered agent service:

• Wyoming LLC with EIN: $249, or $348 with a US bank account application.
• Delaware corporation with EIN: $358.

A Wyoming LLC costs $121 a year to keep active, or $421 with the annual federal return. A US business address with your own suite number is $60 a year. See what a US LLC costs every year.

Banking and documents

Use your Brunei passport. For proof of address, a DES electricity bill, a water bill, an Imagine or DST bill, or a bank statement.

US banks and fintechs generally accept Bruneian owners. What helps:

• a specific description of the business and its customers;
• an English website;
• invoices or supplier contracts;
• a US business address with your own suite number.

Payments to BIBD, Baiduri Bank, Standard Chartered Brunei or TAIB arrive as US-dollar transfers. BIBD and TAIB operate on Islamic principles and can hold the funds in Shariah-compliant accounts. See US business bank accounts for non-residents, Stripe for non-residents and why banks reject non-resident applications.

Mistakes to avoid

• Hiring US staff through a single-member LLC, which turns its profits into US-taxed income of its Bruneian owner.
• Paying dividends from a US corporation to Brunei at 30% with no credit at home.
• Funding the company with interest-bearing loans when you want it to be Shariah-compliant.
• Forgetting state sales tax on US online sales.
• Missing Form 5472 in a year when no US tax was due.
