AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A US LLC with you and a Nigeria-resident co-founder as members is taxed as a partnership by default, and the IRS requires the LLC to withhold tax on effectively connected income allocated to a foreign partner (37% for an individual). An S corporation is ruled out because it cannot have nonresident alien shareholders. Many founders choose either a two-member LLC with a careful operating agreement or a C corporation if they plan to raise investment.
The pattern is common: one founder moved to the US, the other stayed in Lagos or Abuja, and the business sells to customers in America. Which US entity you choose affects tax, paperwork and what investors will accept. Tax points here are information, not advice; a US preparer who works with foreign owners should confirm your case.
Your options at a glance
| Structure | How the IRS treats it | Nigeria-resident co-founder |
|---|---|---|
| Two-member LLC (default) | Partnership: files a partnership return; members get K-1s | Allowed; LLC must apply section 1446 withholding on their share of effectively connected income |
| LLC electing corporate tax (Form 8832) | Taxed as a corporation | Allowed |
| S corporation | Pass-through corporation | Not allowed: no nonresident alien shareholders |
| C corporation | Pays corporate tax; dividends taxed when paid | Allowed; usual choice for venture investment |
The two-member LLC and section 1446
The IRS says a domestic LLC with two or more members is a partnership for tax by default. When a partnership has income effectively connected with a US trade or business, it must withhold on the share allocable to each foreign partner. The IRS page (reviewed July 2026) gives the rate as 37% for non-corporate foreign partners and 21% for corporate ones. The mechanics:
- Form 8813 to pay the withheld tax to the Treasury;
- Form 8804, the partnership's annual return of its withholding liability, with a Form 8805 for each foreign partner;
- a copy of Form 8805 to each foreign partner, even if no tax was paid;
- Form 8804-C, which a foreign partner can use to certify deductions or losses that reduce the withholding.
The tax is due on income allocated, whether or not the LLC actually pays the money out. That catches founders who leave profits in the business. Budget for it from the first profitable year.
Selling a stake has its own rule: under section 1446(f), the buyer of a partnership interest must generally withhold 10% of the amount realised where the gain would be effectively connected.
A worked example
As an example only: a Houston LLC owned 50/50 by you and a co-founder in Abuja has $100,000 of effectively connected taxable income for the year and decides to keep it all in the business.
- Income allocated to the Abuja co-founder (example)
- $50,000
- Section 1446 rate, non-corporate foreign partner
- 37%
- Withholding the LLC must pay
- $18,500
- Cash distributed to the co-founder
- $0
The LLC owes the $18,500 even though nothing was paid out, which is why the operating agreement should allow tax distributions and the LLC should hold cash for it. The co-founder may later file a US return to settle the actual tax due; the Form 8805 copy the LLC must give them shows the amount withheld on their behalf.
Why not an S corporation?
The IRS Form 2553 instructions say an S corporation cannot have nonresident alien shareholders (other than in a narrow trust exception). A co-founder living in Nigeria who is not a US citizen or resident for tax would end the election. If you already have an S corporation and plan to bring in a Nigeria-based partner, deal with this first.
The C corporation route
A C corporation pays corporate tax on its profits, and shareholders are taxed on dividends. It does not pass income through, so there is no section 1446 withholding on a foreign shareholder's share of profits. It is also the structure most US investors expect. The trade-off is two layers of tax on distributed profit. See C corporations for founders raising money and LLC or corporation.
There is no income tax treaty between the US and Nigeria, according to the IRS treaty list, so treaty reductions are not available on either side.
What the operating agreement should cover
- Capital: who puts in what, in cash or work, and what happens if more is needed.
- Percentages and vesting, so a co-founder who leaves early does not keep a full share.
- Roles and who may sign contracts, open accounts and hire.
- How decisions are made and how deadlock is broken.
- Tax distributions, so the LLC can cover withholding and each member's tax.
- Transfers: who can sell, to whom, and the right of first refusal.
- What happens on death, divorce or relocation.

Paperwork that changed in 2026
FinCEN's beneficial ownership page (updated August 2026) says a final rule effective 14 August 2026 exempts US-formed companies from beneficial ownership reporting. Your bank will still identify owners of 25% or more when you open an account.
Where Pryme fits
When one founder is in Lagos and one in Houston, both need to see the same money. A Pryme Business Account holds NGN and USD in one place, and the Chief of Staff agent prepares work that a named person approves above a set ceiling, with each action recorded.
