Overview: Consultants with a US LLC
A US LLC gives consultants a professional entity that US clients trust, access to US payment infrastructure, and liability protection. Many large US companies require consultants to invoice through a US entity.
Best Business Structure
For consultants, we recommend: Single-Member LLC (Disregarded Entity)
A US LLC gives consultants a professional entity that US clients trust, access to US payment infrastructure, and liability protection. Many large US companies require consultants to invoice through a US entity.
Tax Considerations for Consultants
Consulting income is generally sourced where the services are performed. If you perform all consulting work outside the US, the income is typically not ECI even if paid by US clients. However, if you occasionally travel to the US for client meetings, that time spent in the US could create ECI for the portion of services performed in the US.
Important Note for Consultants
Non-resident consultants who visit the US for short-term projects should check their country's tax treaty with the US. Many treaties provide an exemption for independent personal services if you're present in the US for fewer than 183 days and your income doesn't exceed a threshold (often $3,000). Without a treaty, any US-source consulting income is subject to US tax.
Required Tax Forms
As a non-resident consultant with a US LLC, you'll typically need these forms:
- Form 5472 + Pro Forma 1120 (required annually)
- Form W-8BEN or W-8BEN-E (for clients requesting withholding certificates)
- Form 1040-NR (if you have US-source consulting income)
- Form W-7 (ITIN application)
Key Filing Deadline
Form 5472 + Pro Forma 1120: Due April 15 (extension available to October 15). Penalty for non-filing: $25,000. This applies even if your LLC had zero income.
Common Deductions for Consultants
These business expenses are typically deductible for consultants operating through a US LLC:
- Professional development and certifications
- Conference and networking event expenses
- Marketing and business development costs
- Professional liability insurance
- Software and research tools
- Client entertainment expenses (with limitations)
- Home office expenses
- Travel to client sites
Tips for Tax Compliance
- Get a W-8BEN or W-8BEN-E to your US clients before they pay you
- If you visit the US for client work, track your days carefully
- Consider whether your consulting constitutes independent personal services under treaty
- Structure contracts to clearly define where services are performed
- Invoice through your LLC for all US client work
- Maintain detailed records of all transactions with the LLC
