Overview: Software Developers with a US LLC
Software developers use US LLCs to contract with US tech companies, publish on the App Store and Google Play, and access US developer programs. Many US clients prefer to work with US-based entities for IP protection and contract simplicity.
Best Business Structure
For software developers, we recommend: Single-Member LLC (Disregarded Entity)
Software developers use US LLCs to contract with US tech companies, publish on the App Store and Google Play, and access US developer programs. Many US clients prefer to work with US-based entities for IP protection and contract simplicity.
Tax Considerations for Software Developers
Software development services performed entirely outside the US are generally not ECI. However, if you develop software that generates US royalties (licensing, SaaS subscriptions from US customers), those royalties may be subject to US withholding. App store revenue is typically classified as royalty income.
Important Note for Software Developers
Software developers should understand the difference between selling development services (service income, sourced where performed) and licensing software (royalty income, sourced where the payer is located). This distinction affects your US tax obligations significantly. Development services performed outside the US are generally not taxable, while royalties from US licensees may be subject to 30% withholding (reduced by treaty).
Required Tax Forms
As a non-resident software developer 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 and platforms)
- Form 1040-NR (if you have US-source income)
- Form W-7 (ITIN application)
- Form SS-4 (EIN 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 Software Developers
These business expenses are typically deductible for software developers operating through a US LLC:
- Development hardware (laptops, monitors, servers)
- Software licenses and developer tools
- Cloud hosting and API costs
- Code review and quality assurance services
- Online courses and technical certifications
- Open-source project contributions (in some cases)
- Professional conferences and meetups
- Co-working space membership
Tips for Tax Compliance
- Distinguish between service income (development work) and royalty income (licensing)
- Register as a developer on Apple/Google with your LLC
- Consider IP assignment agreements between you and your LLC
- If building a product, consider whether a C-corp election makes sense for future investment
- Track time spent on different projects for accurate income allocation
- Use proper contracts that define IP ownership clearly
