Introduction
Indian Chartered Accountants expanding into US tax services will increasingly encounter NRI clients earning US-source self-employment income. Schedule C is often the backbone of these filings, but the compliance nuances for NRIs differ materially from resident taxpayers.
This article equips practitioners with a practical, end-to-end framework to handle Schedule C self-employment tax for NRIs. We cover who is treated as self-employed, how to report income and expenses, when SE tax applies, and where treaty relief changes outcomes.
You will also find NRI-specific scenarios, deduction checklists, and common errors—framed as “how to handle this for your clients.” Where relevant, we flag advanced forms (Forms 461 and 3800), statutory employee differences, and documentation standards that withstand IRS scrutiny.
The goal is simple: help you deliver accurate, defensible US returns while building scalable US tax capability within your CA practice.
Understanding Self-Employment Income for NRIs
Who is considered self-employed under US tax law?
Under IRS rules, a person is self-employed if they carry on a trade or business as a sole proprietor or independent contractor. Income reported on Form 1099-NEC typically indicates self-employment, but facts and circumstances prevail.
Statutory employees are an exception. They receive Form W-2 with the statutory employee box checked; their income is reported on Schedule C, but they are not subject to SE tax on that income.
Resident vs Non-Resident Alien treatment
NRIs classified as Non-Resident Aliens (NRAs) report only US-source income on Form 1040NR. Resident Aliens report worldwide income on Form 1040.
Dual-status years require careful allocation between periods; refer to our guide on dual status tax return preparation when advising clients with mid-year status changes.
Common self-employment scenarios for NRIs
Typical cases include freelance consultants serving US clients, remote tech developers paid by US companies, Amazon FBA sellers with US inventory, and independent contractors receiving 1099-NEC.
Each scenario demands source-of-income analysis and treaty review before concluding Schedule C and SE tax exposure.
What Is Schedule C and Who Needs to File It?
Purpose of Schedule C
Schedule C reports profit or loss from a sole proprietorship. It captures gross receipts, expenses, and net profit that flows into the main return.
For authoritative context, see the IRS overview of Schedule C (Form 1040).
Who must file Schedule C
Sole proprietors, freelancers, gig workers, and single-member LLCs (disregarded entities) file Schedule C. Qualified joint ventures may split income and expenses between spouses, subject to eligibility.
Agricultural activities are reported on Schedule F, not Schedule C—an important distinction for NRI clients with US farm income.
Schedule C vs other business schedules
Partnerships file Form 1065; S-corporations file Form 1120-S. Misclassification leads to penalties and amended returns.
How to Report Self-Employment Income on Schedule C
Part I – Income
Report gross receipts from US-source activities, including amounts received via platforms and direct client payments. Reconcile totals to 1099-NEC forms and client books.
Foreign-source income is included only if taxable in the US under sourcing rules and treaty positions.
Part II – Business Expenses
Deduct ordinary and necessary expenses incurred to earn the income. Common categories include advertising, software subscriptions, professional fees, internet, and depreciation.
Be mindful of capitalization rules and depreciation elections, particularly for equipment used partly outside the US.
Part III to V – Additional details
Inventory accounting (Part III) applies to sellers like Amazon FBA. Parts IV and V require vehicle details and other expenses—often the first areas reviewed in audits.
Practitioner Tip: Maintain mileage logs contemporaneously; reconciling after year-end invites disallowance.
What Is Self-Employment Tax and How Is It Calculated?
Understanding Self-Employment Tax
SE tax funds Social Security and Medicare at a combined 15.3% on net earnings. The Social Security portion applies up to the annual wage base.
Role of Schedule SE
Schedule SE computes SE tax based on Schedule C net profit. Refer to IRS guidance on Schedule SE and self-employment tax for calculation mechanics.
When NRIs may be exempt from SE tax
Under Totalization Agreements, NRIs covered by Indian social security may be exempt from US SE tax. Proper Certificates of Coverage are essential.
Form 461 can limit excess business losses; plan carryforwards proactively.
Business Expenses and Deductions Available to NRIs
Ordinary and necessary business expenses
Allowable deductions include software, cloud services, accounting fees, insurance, and depreciation. Credits may be available via Form 3800 for eligible activities.
Home Office Deduction
NRIs may claim home office deductions if the space is used exclusively and regularly for business. Allocation must be reasonable and well-documented.
Vehicle and travel expenses
Choose between standard mileage and actual cost methods. Actual costs include fuel, repairs, insurance, registration, and depreciation.
Travel requires substantiation of business purpose, dates, and amounts.
NRI-Specific Deduction Checklist and Compliance Tips
Commonly missed deductions for NRIs
Distinguish foreign tax credits from business deductions; do not double-count. Treaty benefits must be disclosed consistently.
Forms and records to maintain
Retain invoices, contracts, mileage logs, and Certificates of Coverage. Keep records for at least 7 years.
Common errors to avoid
Avoid overstating expenses, misclassifying income, or ignoring Form 461 limits. Align facts across years to reduce audit risk.
Conclusion
Schedule C and SE tax issues for NRIs require precise classification, sourcing, and documentation. Indian CAs who master these mechanics can confidently deliver compliant US returns.
Focus on reconciling income, substantiating deductions, and leveraging treaty relief where available. Build standardized checklists and review protocols to scale this service line.
With disciplined processes, Schedule C engagements become a repeatable and profitable offering within your US tax practice.
