US & EU Compliance Centre

1. US Tax Compliance Overview

The US tax system has specific requirements for anyone receiving US-source income — including freelancers abroad. Understanding your classification and which forms to use is essential to avoid over-withholding and stay compliant.

Important Disclaimer

This guide is for informational purposes only and does not constitute tax advice. Tax obligations vary by individual circumstance. Always consult a qualified tax professional for your specific situation.

US Persons (Citizens, Green Card Holders, Resident Aliens)

Provide Form W-9 to US clients — includes your SSN or EIN
Clients report payments to you on Form 1099-NEC (if $600+ in a year)
Report all freelance income on Schedule C (Form 1040)
Pay self-employment tax (15.3%) via Schedule SE
Make quarterly estimated tax payments using Form 1040-ES

Non-US Persons (Foreign Freelancers)

Provide Form W-8BEN to claim foreign status and treaty benefits
Most freelance/independent personal services income is not subject to US withholding if performed entirely outside the US
Use Form W-8ECI only if your income is "effectively connected" with a US trade or business
Withholding rate defaults to 30% without a valid W-8 form on file
Tax treaties between the US and your country may reduce or eliminate withholding on certain income types

2. EU VAT Obligations for Freelancers

VAT (Value Added Tax) rules for freelancers selling services to EU clients depend on whether your client is a business (B2B) or a consumer (B2C), and where they are located.

B2B Services (Business Clients)

When both you and your client are VAT-registered businesses, the reverse charge mechanism applies:

You issue a VAT-exempt invoice (no VAT charged)
Your client accounts for VAT in their own country via the reverse charge
Include your client's VAT number and a reverse charge note on the invoice
You generally do not need to register for VAT in the client's country

B2C Services (Consumer Clients)

For services to non-business clients, VAT is charged at the rate of your own country:

Charge your local VAT rate on the invoice
If your country has a VAT registration threshold, you may not need to register below it
For digital services to EU consumers, the VAT MOSS scheme may apply

VAT MOSS (Mini One Stop Shop)

If you sell digital services (e-books, software, online courses, etc.) to consumers in other EU countries, VAT MOSS lets you register and file in one country instead of every country you sell to. The tax is then distributed to the correct member state.

3. Invoicing Requirements

Both the US and EU have specific requirements for what must appear on a freelancer's invoice. Non-compliance can delay payments or create tax issues.

US Invoice Requirements

Your name / business name and address
Client's name and address
Invoice number (unique, sequential)
Invoice date and payment due date
Description of services rendered
Amount due and payment terms
Tax ID (SSN/EIN) — only if requested for 1099

EU Invoice Requirements

Your name, address, and VAT registration number
Client's name, address, and VAT number (B2B)
Unique sequential invoice number
Invoice date and supply date (if different)
Description of services and quantity
Net amount, VAT rate, and VAT amount per line
Reverse charge statement (if applicable)
Currency of the invoice

4. Form Reference Guide

Quick-reference cards for the most common US tax forms freelancers encounter:

Form W-9 — Request for Taxpayer Identification Number

Who: US persons (citizens, residents, US entities).
When: When a US client requests it before making payment.
Purpose: Provides your TIN (SSN or EIN) so the client can issue a 1099.

Form W-8BEN — Certificate of Foreign Status

Who: Non-US individuals (foreign freelancers).
When: When receiving US-source income and a client or platform requests it.
Purpose: Certifies foreign status and claims tax treaty benefits to reduce withholding. Valid for 3 years.

Form W-8BEN-E — For Foreign Entities

Who: Foreign companies, LLCs, or other entities (not individuals).
When: Same as W-8BEN but for business entities.
Purpose: Certifies foreign entity status and claims treaty benefits. Includes FATCA status.

Form W-8ECI — Effectively Connected Income

Who: Non-US persons with income effectively connected to a US trade or business.
When: When you operate through a US business or have a US office.
Purpose: Exempts income from withholding but requires filing a US tax return (1040-NR).

5. Key Deadlines & Filing Dates

6. Penalties & Common Mistakes

Avoid these common pitfalls that can lead to penalties, over-withholding, or delayed payments:

Not Submitting W-8BEN to US Clients

Without a valid W-8BEN, US clients or platforms must withhold 30% of your gross payment. Many freelancers lose thousands simply because they didn't submit the form. Use our Tax Compliance Tool to determine which form applies to you.

Missing Quarterly Estimated Tax Payments (US)

The US requires pay-as-you-go tax payments. If you owe $1,000+ in tax for the year, you must make quarterly payments. Failure to do so results in underpayment penalties — even if you file on time.

Incorrect VAT Treatment on EU Invoices

Charging VAT when the reverse charge applies (or vice versa) creates compliance issues for both you and your client. Always verify your client's VAT registration status and include the correct notes on your invoice.

Poor Record Keeping

Disorganised records lead to missed deductions, incorrect filings, and stress during tax season. Use our Invoice Generator and Receipt Generator to maintain professional documentation from day one.
