Pass-Through Taxation
Pass-through taxation is a US business structure where income "passes through" to the owner's personal tax return instead of being taxed at the business level. For non-US founders building US LLCs, this is usually the default and simplest option.
What Is Pass-Through Taxation?
In the US tax system, pass-through entities do not pay corporate income tax. Instead, all profits and losses flow directly to the owner's personal tax return. The business itself files an informational return, but the actual tax is paid by the individual.
A simple example: you are a German founder with a US LLC earning $50,000 in net profit. The LLC files Form 1065 (partnership return) or Schedule C (sole proprietor). You report that $50,000 on your personal tax return and pay tax on it once, at your individual rate. There is no separate business-level tax.
Why This Matters for Non-US Founders
Pass-through taxation avoids double taxation. A C Corporation, by contrast, pays tax on its profit, then shareholders pay tax again on dividends. That penalty is costly and rarely makes sense for early-stage founders.
Most US LLCs default to pass-through treatment. A single-member LLC (owned by one person) is treated as a sole proprietorship unless you elect otherwise. A multi-member LLC is treated as a partnership.
How It Fits Your US Journey
When you form a US LLC as a non-US founder (using an ITIN instead of a Social Security number), you will typically use pass-through taxation. You will need a US EIN to open a business bank account and accept US clients or investors. Your ITIN and EIN together unlock remote banking, credit cards, and professional credibility.
Founders Credit handles the full LLC formation, ITIN application, EIN registration, and banking setup so you can focus on growth. The pass-through structure means your US business integrates cleanly with your personal finances and simplifies annual compliance.
Key Points
- Income is taxed once, at the owner level, not twice
- The business files an informational return (Form 1065 or Schedule C)
- Standard default for US LLCs, especially for founders
- Requires honest and timely reporting on personal tax returns
- Works globally: non-US residents can use pass-through US LLCs with proper ITIN setup
Comparison: Pass-Through vs. C Corporation
| Feature | Pass-Through (LLC/Sole Prop) | C Corporation |

| Business-level tax | No | Yes (21% federal) |
| Owner-level tax | Yes (on distributed profit) | Yes (on dividends) |
| Total taxation | Single tax | Double tax (usually) |
| Filing complexity | Simple (Form 1065 or Schedule C) | Complex (Form 1120, separate entity) |
| Best for | Early founders, service providers | Venture-backed startups, retention |
Important Caveat for Foreign-Owned LLCs
If your LLC is foreign-owned and taxed as a disregarded entity (single-member, no election), the IRS still requires Form 5472 (information about foreign ownership) and may require a pro-forma Form 1120 annually, even at zero income. Non-compliance carries a $25,000 penalty per Form 5472. This is informational and does not itself calculate tax, but must be filed if you have a US trade or business.
Founders Credit ensures your ITIN and Form 5472 compliance from day one so you avoid costly mistakes.
Frequently asked questions
Is pass-through taxation the same as not paying US tax?
No. You still owe US tax on all business income; pass-through means it is taxed once at your personal rate, not at both business and personal levels.
Can I change from pass-through to C Corporation later?
Yes, you can elect to be taxed as a C Corporation (using Form 8832), but this is rarely done early on.
Do I need to file US tax returns if my LLC earned zero profit?
Yes, you must still file an informational return (Form 1065 or Schedule C) and likely Form 5472 if foreign-owned, even at zero income.
What is a pro-forma 1120 for a foreign-owned LLC?
A pro-forma (hypothetical) corporate tax return filed alongside the informational partnership return to show what tax would be owed if the LLC were treated as a corporation.
Does pass-through taxation work for non-US tax residents?
Yes. Your US LLC will be subject to US tax on US business income regardless of your residence. Your home country may also tax it if they claim worldwide income; consult a cross-border accountant.
