Foreign-owned and U.S.-based companies must meet federal and state compliance requirements. This guide covers key annual filings, including IRS forms, state franchise taxes, and Form 5472, tailored to the needs of cross-border and domestic businesses.
What Is Annual Tax Filing in the USA?
Annual tax filing in the USA refers to the mandatory submission of financial and business information to federal and state authorities each year. These filings ensure that a company is in good standing and compliant with U.S. tax laws, regardless of whether it earned any income during the year.
For foreign-owned companies, annual tax filing typically involves reporting to the Internal Revenue Service (IRS) and to the state in which the business is incorporated. This includes income tax returns, franchise tax payments, and informational filings such as Form 5472 for foreign-owned entities.
Key aspects of U.S. annual tax filing include:
- Filing a federal tax return with the IRS based on the company’s entity type (LLC, C-Corp, etc.)
- Submitting state-level filings like franchise tax reports or annual statements
- Disclosing foreign ownership through forms like Form 5472, even if no income was earned
- Keeping the company’s Employer Identification Number (EIN) and registered agent information current
- Ensuring proper bookkeeping and record retention for audit readiness
Whether operating a holding company, remote business, or active U.S. subsidiary, annual tax filing is a legal obligation that applies to all U.S.-registered entities. Failure to comply can lead to penalties, interest charges, and even dissolution of the company.
Filing Requirements for Annual Compliance in USA
Filing requirements differ based on the type of entity (LLC, C-Corp, Partnership) and whether the business is domestic or foreign-owned. Here’s a breakdown:
1. Federal Tax Filings (IRS)
| Entity Type | Required Forms | Deadline | Notes |
|---|---|---|---|
| LLC (Single-Member) | Form 1040 + Schedule C (if owned by U.S. person) OR Form 5472 + Pro Forma 1120 (if foreign-owned) | April 15 | EIN mandatory |
| LLC (Multi-Member) | Form 1065 + K-1s | March 15 | Treated as partnership |
| C-Corp | Form 1120 | April 15 (calendar year) | Flat 21% corporate tax |
| S-Corp | Form 1120S | March 15 | Not eligible for non-residents |
| Foreign-Owned LLC | Form 5472 + Pro Forma 1120 | April 15 | Mandatory even with $0 income |
Penalty for failing to file Form 5472: Minimum $25,000 per year

2. State-Level Annual Reports & Franchise Tax
Each state has different rules. Most foreign founders register in Delaware, Wyoming, or Florida. Here’s a look at Delaware, the most common:
| Requirement | Form | Due Date | Fees |
|---|---|---|---|
| C-Corp Franchise Tax | Franchise Tax + Annual Report | March 1 | Starts at $225; can exceed $100,000 |
| LLC Annual Tax | Flat Franchise Tax (no report) | June 1 | $300 |
| Registered Agent Maintenance | Not a filing, but ongoing | Annual | ~$100–$300/year |
3. Employer Identification Number (EIN)
- EIN is required for opening U.S. bank accounts, paying U.S. taxes, or processing payments via Stripe, PayPal, etc.
- No annual filing for EIN, but notify IRS if ownership or address changes.
- Apply or update via: IRS EIN Portal
4. Form 5472: Essential for Foreign-Owned LLCs
If your U.S. LLC is 100% foreign-owned, even if inactive, you must file:
Required for reporting any “reportable transactions” between the entity and its foreign owner (e.g., funding, expenses, transfers).
5. State Sales Tax Nexus and Registration
If your U.S. entity sells goods/services to customers within a state, you may trigger sales tax nexus:
- Threshold: Often $100,000 in sales or 200 transactions annually
- Must register in that state and file periodic sales tax returns
- Use tools like Commenda for sales tax automation

6. Bookkeeping and Record Retention
The IRS requires that businesses retain:
- Receipts
- Contracts
- Invoices
- Financial statements
- Bank records
For at least 3 years (best practice: 5–7 years). Organized records help during audits and ensure accurate tax filings.

Common Mistakes Foreign Companies Should Avoid
- Missing Form 5472 — One of the most overlooked filings; it’s mandatory for 100% foreign-owned LLCs.
- Assuming zero income = zero filing — The IRS still expects returns, even with no revenue.
- Forgetting franchise tax — Especially in Delaware; can lead to company dissolution.
- No registered agent renewal — All states require an active agent; missing this can void your company’s existence.
- Incorrectly classifying your LLC — Improper filing as S-Corp (which foreigners cannot own) leads to rejections.
