Why Understanding US Business Taxes is Important

If you’re a non-resident running a business in the US, understanding your tax obligations is crucial. Many international entrepreneurs believe that if they don’t live in the US, they don’t owe taxes—but that’s not always the case.

Whether you operate an LLC, C-Corp, or any other entity, you must comply with US tax laws to avoid IRS penalties and maintain good standing. This guide explains US business taxes for non-residents in 2025, key filing requirements, and recent tax updates.

Do Non-Residents Need to Pay US Business Taxes?

If you are a foreign entrepreneur with a US-based business, your tax obligations depend on:

• Your business structure (LLC, C-Corp, etc.).
• Whether your business has effectively connected income (ECI) in the US.
• If you have a physical presence in the US (employees, office, etc.).
• Whether you generate US-source income (selling to US customers, working with US suppliers, etc.).

Who Pays US Business Taxes?

Single-Member LLC (Disregarded Entity) – If your LLC has US income, you must file taxes, but profits pass through to the owner.
Multi-Member LLC – Taxed as a partnership, meaning each owner must report income based on their share.
C-Corp – Pays corporate income tax (21%) + owners pay taxes on dividends.
S-Corp – Non-residents cannot own an S-Corp.

If you only sell digital products/services from outside the US and have no US presence, employees, or inventory, you may not owe US taxes. However, you must still file tax forms to report business activity.

US Tax Obligations Based on Business Type

Single-Owner Foreign LLC

A foreign-owned Single-Member LLC (SMLLC) is a disregarded entity for tax purposes. However, you must:

• File Form 5472 & Pro Forma 1120 (mandatory for all foreign LLCs).
• Report any US-generated income on Form 1040-NR (Non-Resident Tax Return).
• If the LLC has no US-source income, you may not owe taxes but still must file compliance forms.

Multi-Owner Foreign LLC

A multi-member LLC is treated as a partnership, meaning:

• Each owner reports their share of income on Form 1065.
• All foreign owners must file Form 1040-NR if they have US-source income.
• If you sell to US customers, taxes may apply based on tax treaties between your country and the US.

C-Corp Owned by Non-Residents

If a non-resident owns a C-Corp, the company is taxed as follows:

• 21% corporate tax rate on net profits.
• If the company distributes dividends, foreign shareholders may owe a 30% withholding tax (or lower, based on tax treaties).
• The C-Corp files Form 1120 (US Corporate Tax Return).

US Tax Filing for Digital Nomads & Remote Entrepreneurs

• If you run a 100% online business with no US employees or office, your tax liability depends on how you receive payments.
• Accepting Stripe, PayPal, or US bank transactions could create “effectively connected income (ECI)”, meaning you may have to pay taxes.
• Even if you don’t owe taxes, compliance filing is required to keep your business legally active.
