Managing US Business Travel from India: GST, INR Billing, and Multi-Currency Explained

An Indian company sending 20 employees to the US in 2026 handles three compliance frameworks simultaneously.

India-side GST applies at 18% on TMC service fees, with GSTIN capture and Input Tax Credit (ITC) eligibility. TDS on TMC payments falls under Section 194C at 1 to 2%. TCS on overseas tour packages falls under Section 206C(1G) at 5% up to ₹7 lakh per year or 20% above that.

Plus US-side IRS Publication 463 substantiation applies to any US expense claims.

Getting one framework wrong shows up at quarterly GST return filing, income tax audit, or the US IRS if a traveler claims US expenses without documentation. Getting all three right requires operational workflow, not just tax knowledge.

This guide is for Indian CFOs, controllers, AP managers, tax heads, and Chartered Accountants running US business travel programs from Indian entities in 2026.

We cover the three compliance frameworks in detail (GST mechanics, TDS on TMC services under Section 194C, TCS on overseas tour packages under Section 206C(1G)), when to bill in INR versus USD, how multi-currency corporate cards and forex mechanics actually work, the six common India-to-US compliance mistakes finance teams make, and the seven-step operational playbook that keeps quarterly filings clean.

Three compliance frameworks Indian companies handle simultaneously

Three distinct tax frameworks govern India-to-US corporate travel in 2026. Each has different rates, different triggers, and different filing requirements.

• Framework 1: GST: Governed by the CGST, SGST, and IGST Acts. Applies to domestic TMC service fees at 18% and to domestic flight legs at 5 or 12%. International flights from India are zero-rated. ITC eligibility depends on whether the travel is for business purposes.
• Framework 2: TDS on payments to contractors: Section 194C of the Income Tax Act. Applies to payments made to travel management companies, travel agents, and vendors. Rate is 1% for individual or HUF payees, 2% for other entities. Triggers when a single transaction exceeds ₹30,000 or aggregate payments exceed ₹1,00,000 per year.
• Framework 3: TCS on overseas tour packages: Section 206C(1G) of the Income Tax Act. Applies to sale of overseas tour packages. Rate is 5% up to ₹7 lakh per financial year and 20% above that threshold. Whether it applies depends on how the travel is structured, not just where the traveler is going.

Getting all three right requires knowing which framework triggers on which transaction. The next three sections cover each in operational detail.

GST on US business travel: what to charge, claim, and file

GST mechanics on India-to-US business travel split cleanly into four rules.

• Rule 1: International flights are zero-rated: Under Section 16 of the IGST Act, international flights from India carry zero GST on the fare. The airline still issues an invoice, but GST is nil on the international leg. Ancillary services (seat selection, meals, extra baggage) may attract GST at standard rates.
• Rule 2: Domestic flight legs are standard-rated: A domestic leg (Bangalore to Delhi as part of a Bangalore-Delhi-New York itinerary) attracts GST at 5% for economy or 12% for premium economy, business, and first. Airlines issue standard GST invoices on domestic legs.
• Rule 3: TMC service fees attract 18% GST: Travel management companies and travel agents charge 18% GST on their service fees. This is a business expense with ITC eligibility where the travel is for business purposes and the GSTIN is captured at booking.
• Rule 4: US-side hotels, meals, and ground transport carry no Indian GST: Expenses incurred in the US are foreign-supplier transactions outside the GST net. They flow through the expense system in USD and get converted to INR for accounting purposes.

Operational workflow for GST:

• Capture GSTIN at booking on every India-side invoice
• Verify TMC invoices show zero-rated on international flight legs
• Book domestic legs separately if the TMC's booking flow does not split correctly
• Monthly reconciliation of GSTR-2A/2B to catch TMC invoicing errors
• Include US-travel-related ITC claims in GSTR-3B with clear documentation

A finance manager at a multi-country manufacturing customer told us their program needed to "handle policies across multiple currencies (USD, INR, EUR)" and that European operations required per-diem and mileage reimbursement rates by country because compliance requirements were legally mandated.

The multi-jurisdiction reality means Indian companies with US travel plus European or APAC exposure need platform-level multi-currency and multi-jurisdiction support, not spreadsheet workarounds.

TDS on TMC services under Section 194C: 1% or 2%

TDS under Section 194C triggers on payments to travel management companies, travel agents, and vendors providing services (as distinct from airline ticket purchases directly).

When TDS applies: Payments to TMCs for service fees, booking fees, program management fees, and reporting services. Direct airline ticket purchases from IATA-recognized carriers do not attract TDS on the ticket itself, but do attract TDS on any commission or service fee component.

Rate

• 1% if the payee is an individual or Hindu Undivided Family (HUF)
• 2% if the payee is any other entity (company, LLP, partnership firm)

Trigger threshold

• Single transaction exceeds ₹30,000, OR
• Aggregate payments to the same payee exceed ₹1,00,000 in a financial year

How to deduct

• Deduct TDS at the invoice-processing step, not at payment
• Deposit TDS by the 7th of the following month (or 30 April for March-end deductions)
• File TDS return quarterly in Form 26Q

Common mistake: Some finance teams deduct TDS on the ticket portion of a TMC invoice as well as the service fee. TDS applies to the service component, not the ticket. Deducting on the ticket portion produces reconciliation errors with the TMC and understates payable amounts. Confirm the invoice breakdown before deducting.

TCS on overseas tour packages under Section 206C(1G): 5% and 20% thresholds

TCS under Section 206C(1G) applies to sellers of overseas tour packages. The rate is 5% up to ₹7 lakh per financial year and 20% above that 

When TCS applies: 

TCS applies when the transaction is characterized as an overseas tour package. A tour package under the section is broadly a bundled offering that includes travel, lodging, and other components sold together at a single price.

When TCS typically does NOT apply: 

• Air tickets booked separately from lodging (unbundled)
• Direct hotel bookings not sold as part of a tour package
• Business travel booked leg-by-leg through a TMC where flight and hotel are billed separately
• Corporate travel where the TMC does not sell a bundled tour package

Adjustment against income tax liability.

TCS collected under Section 206C(1G) is credited to the traveler's or the entity's PAN and can be adjusted against income tax liability at year-end. It is not a permanent tax; it is a collection-at-source mechanism.

Implication for Indian corporates

Most corporate US business travel booked through a TMC on an unbundled basis (flight, hotel, ground transport booked as separate line items) does not trigger TCS. Confirm the invoice structure with your TMC. If the TMC bills as a bundled tour package, TCS applies at the applicable rate.

INR vs USD billing: which currency and when

The choice of billing currency for US business travel affects GST paperwork, forex costs, and reconciliation complexity.

Bill in INR through an Indian TMC when:

• International flight is the primary spend line
• Hotel is booked through the Indian TMC's international inventory
• The traveler is on India-issued corporate cards
• The company files primarily in INR

Bill in USD through a US-side vendor when:

• Hotel is booked directly with a US chain that does not accept Indian TMC billing
• Ground transport is post-arrival (Uber, rental car in the US)
• Meals and incidentals are unavoidably USD
• The traveler carries a USD-denominated corporate card

Implication.

INR-billed transactions carry GST paperwork end-to-end but limit currency-hedging optionality. USD-billed transactions carry no Indian GST but require monthly forex conversion at the applicable RBI reference rate for accounting.

Most Indian mid-market programs land on a hybrid: pre-trip bookings (flight, primary hotel) in INR through the TMC, in-trip incidentals (secondary hotels, meals, ground transport) in USD on the corporate card. The TMC handles the INR side; the corporate card handles the USD side; monthly reconciliation ties both back to the trip record.

For deeper coverage of the corporate card options that pair with this hybrid model, see our guide to business travel and expense cards.

Multi-currency corporate cards and forex mechanics

Multi-currency corporate cards for Indian companies with US travel fall into three categories.

Category 1: INR-issued corporate cards used internationally

Kotak Business Card, HDFC Corporate Card, ICICI Bank Business Cards, Axis Bank Business Cards, and Yes Bank Corporate Cards typically carry 3 to 3.5% forex markup on international transactions, unless a specific zero-forex-markup product is selected.

Some banks offer premium corporate variants (Kotak Wealth, HDFC Signature Corporate) that reduce the forex markup to 1 to 1.5%. Compare markup carefully at corporate card selection.

Category 2: USD-denominated corporate cards for Indian entities

Companies with US subsidiaries can issue USD-denominated corporate cards through the US entity (Chase Ink Business, Amex Business Platinum, Brex, Ramp). These cards spend in USD without forex markup for US transactions and consolidate US spend at the US entity level.

Requires the corporate structure to include a US legal entity. Not accessible to purely India-domiciled companies without US presence.

Category 3: Multi-currency virtual cards

Newer platforms offer virtual multi-currency corporate cards that hold both INR and USD balances. Spend is charged in the destination currency without conversion. Common for platforms integrated with corporate travel systems.

Point-of-sale currency conversion (DCC) trap

At US point-of-sale (hotels, restaurants, rental car counters), the merchant sometimes offers to charge the card in INR instead of USD. This point-of-sale currency conversion (called DCC in banking) applies an exchange rate typically 4 to 8% worse than the card network rate. Always decline DCC and pay in USD.

Six common India-to-US compliance mistakes

Six mistakes recur across Indian finance teams managing US business travel.

• ‍Not capturing GSTIN at booking: Some travel platforms and TMCs allow booking without GSTIN. Every India-issued invoice needs the corporate GSTIN captured at booking. Retroactive GSTIN addition after invoice generation is difficult and sometimes impossible.‍
• Deducting TDS on the ticket portion: TDS under Section 194C applies to the TMC service fee component, not the airline ticket component. Deducting TDS on the full invoice creates reconciliation errors.‍
• Treating US business travel as an overseas tour package for TCS: Most corporate US business travel booked as unbundled flight plus hotel does not trigger TCS under Section 206C(1G). Applying TCS unnecessarily reduces cash flow and creates PAN-mapping confusion.‍
• Accepting DCC at US point-of-sale: The DCC rate is 4 to 8% worse than the card network rate. Travelers accepting DCC to see the INR amount overpay by that margin. Train travelers to always pay in USD.‍
• Missing GSTR-2A/2B reconciliation: Monthly reconciliation of the company's ITC claims against vendor filings catches TMC invoicing errors early. Programs without monthly reconciliation surface errors at quarterly return filing, which is 3x more work to fix.
• Assuming LRS applies to corporate business travel: The Liberalized Remittance Scheme's $250,000 per financial year limit applies to resident individuals for personal purposes. Corporate business travel expenses are outside LRS when properly documented as business. Some finance teams incorrectly restrict business travel against LRS limits.

The seven-step operational playbook for Indian finance teams

Seven ordered steps build an operating workflow that keeps quarterly filings clean and reconciliation predictable.

Step 1: Standardize GSTIN capture at booking

Every India-side booking must capture the corporate GSTIN before invoice generation. Configure the TMC or platform to require GSTIN as a mandatory field. Retrofit is difficult after the fact.

Step 2: Apply zero-rated treatment on international legs

Verify the TMC applies zero-rated GST on international flight fares under Section 16 of the IGST Act. Domestic legs remain standard-rated. If the TMC does not split correctly, book international and domestic legs separately.

Step 3: Deduct TDS at TMC invoice processing

Deduct TDS under Section 194C at the invoice processing step, on the service fee component only. Deposit by the 7th of the following month. File quarterly TDS return in Form 26Q.

Step 4: Evaluate TCS applicability per booking

For each US booking, verify whether the transaction is bundled (tour package) or unbundled (separate flight and hotel). Most unbundled corporate travel does not trigger TCS under Section 206C(1G). Bundled packages do.

Step 5: Choose INR or USD billing per trip leg

Pre-trip bookings (flight, primary hotel) typically bill in INR through the Indian TMC. In-trip incidentals (US ground transport, meals, secondary hotels) bill in USD on corporate cards. Configure the workflow so both flow to the same trip record.

Step 6: Monthly GSTR-2A/2B reconciliation

Match ITC claims against vendor GST filings monthly. Catch TMC invoicing errors, missing GSTINs, and rate misclassifications before quarterly filing.

Step 7: Quarterly return filing with US-travel line items separated

GSTR-1 and GSTR-3B should have clear line-item separation for US-travel-related ITC claims. This supports audit response and simplifies year-end reconciliation.
