How to Pay International Contractors Legally: A US Employer's Step-by-Step Guide

Paying international contractors legally is simpler than paying international employees — but it's not without compliance obligations. US companies frequently make payment errors that create tax liability, banking issues, or contractor disputes. This guide covers the legally compliant approach for each major offshore market.

The Legal Basis for International Contractor Payments

Before making the first payment, ensure the legal foundation is correct: the contractor is genuinely independent (not a misclassified employee), the contract specifies the governing law, payment currency, invoicing requirements, and IP assignment, and both parties have tax identification numbers for their respective jurisdictions.

Payment Methods for International Contractors

Wire transfer (SWIFT)

Direct bank-to-bank international wire is the most straightforward method. Requirements: contractor's IBAN (EU) or account number + SWIFT/BIC code + bank name and address. Fees: $15–$45 per transfer for the sender; potential receiving bank fees on the contractor's side. FX rate: the bank's spot rate plus a markup of typically 1–3%.

Wise (TransferWise) Business

Lower FX markup than banks (0.35–1% depending on currency), transparent fee structure, fast settlement (1–2 business days to India). Widely used for regular contractor payments. Requires Wise Business account setup. Good for regular monthly payments up to $50,000/transfer.

Contractor payment platforms (Deel, Remote)

Platforms like Deel's contractor module or Remote's contractor tool aggregate payments, generate compliant contractor agreements, and handle currency conversion. Fee: typically $35–$49/month per contractor or a percentage. Best for companies managing 5+ international contractors with compliance documentation needs.

PayPal / Payoneer

Fast, accessible, but not ideal for professional B2B contractor payments. Higher fees, less professional invoicing infrastructure, and contractor may face higher inbound fees. Better as a fallback than a primary method.

India-Specific Contractor Payment Rules

FEMA compliance

Foreign payments to Indian contractors fall under the Foreign Exchange Management Act (FEMA). The contractor must have a valid GST registration or declaration of services if above the GST threshold, report foreign income in their ITR, and comply with FEMA repatriation timelines (repatriate within 9 months of service delivery under most categories).

GST on exports

Indian contractors providing services to US companies are exporting services — this is generally GST-exempt (zero-rated) under Indian GST rules. The contractor should issue a zero-rated invoice. Verify they have a GST registration number on their invoices even if GST is zero-rated.

TDS withholding

For contractor payments sourced from India (if you have an India entity), TDS at 10% (Section 194J, professional services) or 1–2% (Section 194C, contracts) must be deducted and remitted. For pure USD payments from a US company with no India PE, TDS obligations on the US company's side are generally nil — but the contractor still has Indian income tax obligations on their ITR.

US Tax Obligations for International Contractor Payments

Form W-8BEN / W-8BEN-E

Before making the first payment to a foreign contractor, collect a completed Form W-8BEN (individual) or W-8BEN-E (entity) from the contractor. This certifies their foreign status and exempts you from US backup withholding (24%) on the payment. Without this form, you're technically required to withhold.

Form 1099 reporting

Form 1099-NEC is not required for payments to foreign contractors (non-US persons). It's only required for US persons. If you collect the W-8BEN certifying foreign status, no 1099 is needed.

FATCA considerations

For larger contractor relationships (above $600 annually, and particularly for service-based payments), ensure your contractor's bank has FATCA compliance — most major banks in India, EU, and Philippines are FATCA-compliant, so this is rarely a practical issue.

Contractor Invoice Requirements

Your contractor's invoices should include:

• Contractor's legal name and address
• Contractor's tax identification number (PAN in India, NIP in Poland, TIN in Philippines)
• GST registration number if applicable (India)
• Service description with clear reference to the contract and deliverable period
• Invoice amount in agreed currency (USD is fine for most foreign contractor invoices)
• Bank account details (account number, IFSC in India; IBAN + BIC in EU; routing + account in US-based banks)
• Invoice date and payment due date

Contractor vs Employee: The Payment Red Flags

• Paying a 'contractor' at a fixed monthly rate regardless of deliverables — looks like salary
• Paying the same contractor for 12+ consecutive months exclusively — looks like employment
• Including benefits like health insurance or paid leave in contractor agreements — removes the independent contractor distinction
• Reimbursing equipment purchases for a contractor — employees have equipment provided; contractors supply their own
