US Tax Compliance Checklist for Indian Founders with U.S. Companies | 2025 Guide

Expanding to the United States can be a game-changer for Indian entrepreneurs but with opportunity comes responsibility. Navigating the US tax system can feel daunting, especially when your company spans two jurisdictions with different regulations, deadlines, and forms. Missing a single form like 5472 or FBAR could cost you thousands in penalties.

Here’s a comprehensive US tax filing compliance checklist tailored for Indian founders with US entities from filing requirements to cross-border tax treaties.

1. Understand Your Filing Requirements

If you’ve formed a Delaware C-Corp, LLC, or Wyoming entity, your U.S. business has federal (and possibly state) tax obligations. You may be required to file:

• Form 1120 (U.S. Corporation Income Tax Return)
• Form 5472 (for foreign owners or related-party transactions)
• FBAR (FinCEN Form 114) if you have authority over foreign bank accounts
• State tax returns, franchise tax, and annual reports
• As of March 21, 2025, only foreign entities registered to do business in the U.S. are required to file BOI reports under the Corporate Transparency Act. Domestic entities, such as Delaware C-Corps and Wyoming LLCs, are currently exempt from this requirement.

Even if your U.S. company had no income, you must still file zero-revenue forms to remain compliant.

2. Organize Your Financial Records

Keeping accurate records is the bedrock of tax compliance. U.S. accounting follows GAAP (Generally Accepted Accounting Principles), which differ slightly from Indian accounting standards.

You’ll need to prepare:

• Profit & Loss statements
• Balance Sheets
• Payroll and contractor expense records
• Receipts (software, meals, travel, etc.)
• Cross-border payment reports

Tools like QuickBooks Online, Xero, or Virtual CFO platforms streamline reconciliation and audit readiness.

3. Review Changes in Tax Laws

U.S. tax law is dynamic. The IRS, state tax boards, and even international regulations like BEPS 2.0 impact your obligations. For instance:

• Corporate tax rate remains at 21%, but GILTI (Global Intangible Low-Taxed Income) may apply if your U.S. company owns a foreign subsidiary.
• Form 5472 is now mandatory even for single-member LLCs owned by foreigners
• Recent updates to BOI rules under the Corporate Transparency Act require reporting the beneficial owners of US entities

As of 2024, any U.S. business filing 10 or more forms annually (like 1120, 1099s, W-2s) must e-file them under IRS mandate T.D. 9972 even small startups.

4. Maximize Deductions and Credits

Many Indian founders miss out on tax-saving opportunities simply due to lack of local expertise.

Key U.S. tax deductions include:

• Software subscriptions (AWS, HubSpot, Zoom)
• Home office expenses (if managed remotely from India)
• Startup costs up to $5,000
• Travel to the U.S. for business
• Depreciation of equipment and laptops

Potential tax credits:

• R&D tax credit (for software and tech startups)
• Foreign tax credit (if you’ve paid Indian corporate tax)

Use a qualified CPA or Virtual CFO who understands both Indian and U.S. systems to optimize deductions without raising red flags.

Evaluate State-wise Tax Rates & Incentives

Beyond federal taxes, each U.S. state has its own corporate tax structure. Some states are tax-friendly for startups, while others impose higher burdens through corporate income tax, franchise fees, or sales tax.

State-wise Tax Rates & Startup Friendliness Rating (2025):

Tip: Where you incorporate vs. where you operate affects your tax exposure. Even if a company is registered in Delaware, it may still be subject to California taxes if it conducts business in the state.

Working with a Virtual CFO ensures you register only in necessary states, minimize filing burdens, and take advantage of state-specific tax credits, such as R&D credits in California or startup incentives in New York.

5. Assess Quarterly Estimated Payments

For calendar-year corporations, quarterly estimated tax payments are due on April 15, June 15, September 15, and December 15.

For fiscal-year corporations (e.g., year ending March 31), payments are due on the 15th day of the 4th, 6th, 9th, and 12th months of the fiscal year.

(Note: January 15 deadlines generally apply to individuals, not corporations.).

6. Conduct a Comprehensive Tax Review

Before you file your taxes, conduct a complete review of your:

• Financial statements
• Vendor payments (especially international)
• Foreign account disclosures (like Wise, Mercury, or Indian bank accounts)
• Transfer pricing documentation (if billing between U.S. and Indian entities)

Check if you’re eligible for elections (e.g., S-Corp status for tax purposes) or if changes in ownership structure might reduce liability in the next fiscal year.

7. File Your Taxes Timely

Failing to file Forms 5472 or 1120 on time may result in an automatic $25,000 penalty.

Important deadlines:

Filing extensions can buy you time but don’t delay payments interest accrues from April. You must file Form 1120 if your U.S. corporation is active even with zero income. Foreign-owned entities must also file Form 5472 to report reportable transactions.

8. Maintain Communication with Tax Authorities

If you receive an IRS letter, don’t panic but don’t ignore it either. Timely response is crucial. Common notices include:

• CP2100: Incorrect TIN reported
• CP2000: Underreported income
• Notice of Civil Penalty (Form 5472): $25,000 penalty for late or incomplete foreign ownership disclosure, pursuant to IRC §6038A

Proactively update your U.S. business address, registered agent, and EIN records. Your virtual CFO or CPA can respond on your behalf, avoiding miscommunication.

9. Key IRS Deadlines: Forms 5472, 1120, FBAR

These three forms are especially important for Indian founders:

Form 5472

• Required if your U.S. company is 25%+ foreign-owned
• Reports capital contributions, loans, and payments to related parties
• Due with Form 1120

Form 1120

• Corporate tax return for U.S. entities
• Includes income, expenses, deductions, and tax owed

FBAR (FinCEN 114)

• Required if foreign accounts (including Indian) exceed $10,000
• File online through the BSA E-Filing System
• Missing any of these can result in steep penalties and audit risk.

10. What’s Taxable in the US vs. India?

Indian founders often ask: “Do I pay tax in both countries?”

Here’s the basic breakdown:

For example, if your US company earns $100,000 from US clients, it’s taxable in the U.S. But if you repatriate profits to India, those may be taxed again unless offset via DTAA (explained below).

11. Double Taxation Agreement (DTAA) Explained Simply

The DTAA between India and the U.S. helps avoid double taxation on the same income.

• Taxes paid in the U.S. can be claimed as a foreign tax credit in India, subject to DTAA provisions.
• Dividends, interest, and royalties may have reduced withholding rates (5–15%)
• Avoids legal double taxation but not compliance duplication you still file in both countries

This US tax treaty is especially useful if you’re repatriating profits or drawing salary from a U.S. company.

12. Role of a Virtual CFO in Handling Filings

Managing US compliance from India is hard different time zones, unfamiliar terms, and aggressive IRS rules. That’s where a Virtual CFO adds value:

• Ensures monthly reconciliation and documentation
• Files all IRS, state, and FinCEN forms on time
• Handles correspondence with IRS
• Coordinates with your Indian CA for DTAA filings

Final Thoughts
