GST & Tax Guide for IT Professionals and Consultants: Export of Services, TDS, and ITR Filing

Independent IT professionals and consultants sit at an unusual intersection — most of their billing is often to clients outside India, which raises the "export of services" question that domestic-only professionals (like most of the professions covered elsewhere in this series) never need to think about.

Is Billing a Foreign Client Automatically GST-Exempt?

No — a common misconception. Export of services is zero-rated, not exempt, and the distinction matters. Zero-rated means GST registration and the export mechanics (LUT or pay-and-refund) still apply; exempt would mean GST doesn't enter the picture at all. For a service to qualify as an "export of service" under GST, all of these conditions must be met:

• The supplier is located in India
• The recipient is located outside India
• The place of supply is outside India
• Payment is received in convertible foreign exchange (or Indian Rupees where permitted by RBI)
• The supplier and recipient are not merely establishments of the same legal entity (i.e., not billing your own overseas branch/subsidiary)

An IT consultant meeting all five conditions can export under LUT without paying IGST upfront — the same mechanism covered in our dedicated LUT guide. Missing even one condition (e.g., the "recipient" is actually a group company, not an independent client) means it isn't treated as an export, and the transaction may need to be taxed as a normal domestic-equivalent supply.

GST Registration Threshold Still Applies

Even though export income is zero-rated, it still counts toward your aggregate turnover for GST registration purposes — an IT consultant earning ₹25 lakh entirely from a single US client still crosses the ₹20 lakh threshold and needs to register, file LUT, and report the zero-rated export in GSTR-1, even though no tax is actually collected on that income.

Mixed Domestic and Export Billing

Many IT consultants have a mix — a few Indian clients alongside overseas ones. Domestic billing is taxed normally at 18%, while export billing is zero-rated under LUT — both need to be correctly separated and reported in the relevant GSTR-1 tables (export invoices go in a distinct table from regular B2B invoices), and this separation is one of the most common reporting errors for consultants juggling both invoice types.

TDS on Consulting Fees

Domestic clients paying professional/technical fees above ₹30,000 in a year must deduct TDS at 10% under Section 194J — this only applies to payments from Indian entities; foreign clients paying directly from abroad don't deduct Indian TDS. A consultant with both types of clients should expect Form 16A only from domestic payers and reconcile that against Form 26AS, while overseas income needs to be tracked separately from invoices/bank statements since no TDS certificate will exist for it.

Income Tax: Presumptive Taxation Under Section 44ADA

IT consulting is a notified profession under Section 44ADA, so consultants with gross receipts up to ₹75 lakh (95%+ receipts through banking channels, which foreign wire transfers/digital payments typically satisfy) can declare 50% of receipts as taxable income without maintaining full books or getting audited. Given that many independent IT consultants have relatively low direct costs (no major equipment, minimal staff), the actual profit margin is often well above 50% — meaning 44ADA is frequently favourable purely on the tax-rate math, in addition to the compliance simplicity.

Practical Compliance Checklist

• Confirm each overseas client relationship genuinely meets all five export-of-service conditions before treating income as zero-rated
• Register for GST once turnover (domestic + export combined) crosses ₹20 lakh, and file LUT annually before the first export invoice of the year
• Separate domestic and export invoices correctly in GSTR-1 reporting
• Reconcile Form 26AS against Form 16A from domestic clients only; track foreign receipts independently
• Evaluate Section 44ADA against actual books each year based on your real expense ratio

Getting the export-of-service classification and LUT filing right from the start avoids both an unnecessary IGST cash-flow hit and a reporting mismatch later. Our GST registration service and ITR filing service cover both pieces for independent IT consultants.
