If you're an American freelancing or contracting in the UK, your US tax filing can feel disorienting — partly because the familiar US machinery (1099s arriving in January) simply doesn't exist here. UK clients won't send you anything for the IRS, yet you still have to report every penny to it. This guide is the practical forms checklist: exactly what you file, why the UK works differently, and how to handle the contractor-versus-employee question.
The short answer
An American freelancing in the UK files Form 1040 with Schedule C to report their freelance income, plus the cross-border relief forms — Form 2555 (Foreign Earned Income Exclusion) or Form 1116 (Foreign Tax Credit). You generally skip Schedule SE because the US-UK Totalization Agreement exempts you from US self-employment tax (you attach an HMRC certificate of coverage instead). Crucially, UK clients won't issue you a 1099 — that's a US form — so you self-report all income from your own records. Depending on your accounts, FBAR and Form 8938 may also apply.
Key takeaways
- Your core US filing is Form 1040 + Schedule C for freelance income.
- UK clients won't send a 1099 — you self-report everything from your own records.
- Use Form 2555 (FEIE) or Form 1116 (Foreign Tax Credit) to offset US income tax.
- You generally skip Schedule SE — the Totalization Agreement exempts you (certificate of coverage).
- Contractor-vs-employee classification matters in both countries and turns on substance.
Executive summary
For a US freelancer in the UK, the filing picture has three parts. First, income reporting: all your freelance income goes on Schedule C, regardless of whether any client issued a form — and UK clients won't. Second, relief: you offset the US income tax with the FEIE (Form 2555) or the Foreign Tax Credit (Form 1116). Third, self-employment tax: you generally avoid US SECA via the Totalization Agreement, attaching an HMRC certificate of coverage rather than filing Schedule SE. The recurring shock for Americans is the absence of 1099s — but the obligation to self-report is unchanged. Underlying all of it is the contractor-versus-employee question, which determines the whole treatment and turns on the substance of how you work, not the job title.
Why there are no 1099s in the UK
In the US, when a business pays an independent contractor, it issues a 1099-NEC so the IRS can match the income. Americans freelancing for the first time abroad often wait for those forms — and they never come. That's because UK clients operate under UK rules; they have no obligation (or mechanism) to issue US tax forms.
This changes your process but not your duty. You must self-report all your UK freelance income to the IRS on Schedule C, built from your own records — invoices, bank statements, accounting software. If anything, this makes good bookkeeping more important, not less, because nothing else is tracking your income for US purposes.
(If you also freelance for US clients, they may still issue you 1099s — but US-client and UK-client income alike all land on the same Schedule C as worldwide income.)
The US forms checklist
Here's what a typical American freelancer in the UK files on the US side:
| Form | Purpose | When it applies |
|---|---|---|
| Form 1040 | The main US return | Always |
| Schedule C | Reports freelance income and expenses | Always (self-employed) |
| Form 2555 | Foreign Earned Income Exclusion | If you use the FEIE |
| Form 1116 | Foreign Tax Credit | If you use the FTC |
| Schedule SE | Self-employment tax | Usually not — exempt via Totalization |
| FBAR (FinCEN 114) | Foreign account reporting | If accounts cross the threshold |
| Form 8938 | FATCA asset reporting | If assets cross the threshold |
The two you'll almost always file are 1040 + Schedule C. The relief form (2555 or 1116) depends on whether the FEIE or Foreign Tax Credit suits you better. The one you usually skip is Schedule SE — covered next.
Self-employment tax: usually exempt
Like any self-employed American in the UK, you're generally exempt from US self-employment tax under the US-UK Totalization Agreement, because as a UK resident you pay UK National Insurance instead. You evidence this with an HMRC certificate of coverage attached to your US return, and you generally don't complete Schedule SE. The full mechanics — including the certificate process and the fact that the FEIE does not remove self-employment tax — are in our dedicated guide: self-employed in the UK?

The contractor-versus-employee question
One classification sits underneath everything: are you genuinely an independent contractor, or does your arrangement actually look like employment? It matters on both sides:
- In the UK, the distinction affects how you're taxed and whether off-payroll rules (IR35) apply to contractors working through their own companies.
- In the US, it affects which forms and taxes apply — a true independent contractor reports as self-employed on Schedule C; an employment-like arrangement is treated differently.
The classification turns on the substance of the relationship — control, mutuality, who bears the risk — not the label on your contract. Genuinely borderline cases (a long-term "contractor" working like a staff member, for instance) are worth professional review, because getting it wrong has consequences in both countries.
Common mistakes we see
- Waiting for 1099s that never arrive, then under-reporting income.
- Filing Schedule SE and paying self-employment tax when the Totalization exemption applied.
- Poor record-keeping, because no 1099 is tracking income for you.
- Assuming a "contractor" label settles the classification — substance governs.
- Forgetting FBAR/Form 8938 on UK business and personal accounts.
