GST on Forex Conversion: Complete Guide for Travellers, Exporters and Importers (2026)
Every time you buy foreign currency, load a forex card, or send money abroad, a GST charge quietly appears on your invoice. Most people have no idea how it is calculated — or that in many cases, it can be avoided or claimed back. This guide explains everything clearly.
Key Facts at a Glance
- GST rate on forex services: 18% — but NOT on the full amount converted. Only on the “value of service” computed under Rule 32(2) of CGST Rules.
- Maximum GST on any single forex transaction: Rs.10,800 (service value capped at Rs.60,000 by law, regardless of transaction size).
- SAC code: 997153 (Currency conversion and foreign exchange services).
- Inward remittances (export receipts): Zero-rated — no GST on receiving foreign payment for export of goods or services.
- Outward remittances (travel, LRS, import payments): GST applies on the service component.
- Businesses: Can claim Input Tax Credit (ITC) on GST paid for forex services used in business. Individuals cannot.
- Legal basis: Section 15 of CGST Act + Rule 32(2) of CGST Rules, 2017.
The Biggest Myth About GST on Forex — Busted First
Before anything else, let us clear the most widespread misunderstanding that causes panic every time someone sees a GST charge on their bank statement.
“I am converting Rs.5 lakh to USD. The bank will charge 18% GST on Rs.5 lakh = Rs.90,000 GST!”
This belief stops people from transacting and causes unnecessary fear. It is completely wrong.
GST applies only on the small “service value” component, not on the full amount converted.
On Rs.5 lakh conversion, the taxable service value is only Rs.3,000. GST at 18% on Rs.3,000 = just Rs.540. Not Rs.90,000.
GST on foreign exchange is a tax on the service of converting currency — the bank’s fee for doing the conversion — not on the money you are converting. The government has a special formula (Rule 32(2) of the CGST Rules) to calculate this service value, which keeps the GST amount very small even for large transactions.
What is GST on Forex and Who Charges It?
When you walk into a bank or authorised money exchanger (called an Authorised Dealer or AD bank under FEMA) and exchange rupees for dollars, euros, or any foreign currency, the bank is providing you a service. That service is taxable under GST. The tax is at 18% — but crucially, it applies only to the computed value of that service, not the currency amount.
The following entities charge GST on forex services:
- AD Banks (SBI, HDFC, Axis, ICICI, Union Bank, etc.) — for currency purchase, wire transfers, LRS remittances
- Full Fledged Money Changers (FFMC) — Thomas Cook, BookMyForex, ExTravelMoney, Matrix Forex
- Prepaid forex card issuers — Niyo, HDFC ForexPlus, Axis Multi-Currency, etc.
- Online remittance platforms — Wise, Instarem, etc. (for outward transactions)
Every one of these entities must issue a GST tax invoice showing SAC Code 997153, the computed taxable value, and 18% GST split as CGST + SGST (for intra-state) or IGST (for inter-state transactions, which most forex transactions are).
How GST on Forex is Calculated: Rule 32(2) Explained Simply
The government knows that calculating the exact “service value” of a currency conversion in real time is complex. So Rule 32(2) of the CGST Rules gives banks two options to choose from. The bank picks one method and uses it for the entire financial year — it cannot switch mid-year.
Method 1: The Slab Method (Most Common)
Most banks and money changers in India use this method. The service value is calculated in three slabs based on the INR amount exchanged:
| INR Amount Converted | Taxable Value (Service Component) | GST at 18% | Minimum / Maximum |
|---|---|---|---|
| Up to Rs.1,00,000 | 1% of the amount exchanged | 18% of service value | Minimum taxable value: Rs.250 (so minimum GST = Rs.45) |
| Rs.1,00,001 to Rs.10,00,000 | Rs.1,000 + 0.5% of amount exceeding Rs.1 lakh | 18% of service value | — |
| Above Rs.10,00,000 | Rs.5,500 + 0.1% of amount exceeding Rs.10 lakh | 18% of service value | Maximum taxable value capped at Rs.60,000 → Max GST = Rs.10,800 |
Method 2: The Margin/Spread Method (Used by Some Banks)
Under this method, the taxable value is the difference between the rate offered to the customer and the RBI reference rate for that day, multiplied by the total units of currency exchanged.
For example: RBI reference rate for USD is Rs.83.50. Bank offers you Rs.82.80. Difference = Rs.0.70 per USD. If you buy USD 5,000 → Taxable value = Rs.0.70 × 5,000 = Rs.3,500. GST at 18% = Rs.630.
This method results in a higher or lower GST depending on how competitive the bank’s rate is. Banks with better exchange rates will generate lower GST under this method. Online forex platforms often use this method.
Worked Examples: Exactly How Much GST Will You Pay?
Example 1 — Buying EUR 1,000 for a Europe holiday (approx. Rs.91,000)
| INR amount converted | Rs.91,000 |
| Slab applicable | Up to Rs.1,00,000 → 1% of amount |
| Taxable service value | 1% of Rs.91,000 = Rs.910 |
| GST at 18% | Rs.910 × 18% = Rs.163.80 |
| Total GST you pay | Rs.164 (approx.) — Not Rs.16,380 |
Example 2 — Loading Forex Card with Rs.5,00,000 for USA trip
| INR amount loaded | Rs.5,00,000 |
| Slab applicable | Rs.1 lakh to Rs.10 lakh → Rs.1,000 + 0.5% of excess |
| Excess over Rs.1 lakh | Rs.5,00,000 − Rs.1,00,000 = Rs.4,00,000 |
| Taxable service value | Rs.1,000 + (0.5% of Rs.4,00,000) = Rs.1,000 + Rs.2,000 = Rs.3,000 |
| GST at 18% | Rs.3,000 × 18% = Rs.540 |
| Total GST you pay | Rs.540 on a Rs.5 lakh transaction |
Example 3 — LRS wire transfer of Rs.25,00,000 for child’s education abroad
| INR amount remitted | Rs.25,00,000 |
| Slab applicable | Above Rs.10 lakh → Rs.5,500 + 0.1% of excess |
| Excess over Rs.10 lakh | Rs.25,00,000 − Rs.10,00,000 = Rs.15,00,000 |
| Taxable service value | Rs.5,500 + (0.1% of Rs.15,00,000) = Rs.5,500 + Rs.1,500 = Rs.7,000 |
| GST at 18% | Rs.7,000 × 18% = Rs.1,260 |
| Total GST you pay | Rs.1,260 on a Rs.25 lakh remittance |
Even on Rs.25 lakh, the GST is just Rs.1,260 — because the law limits the tax to the service component, not the full amount.
Example 4 — Rs.1 crore import payment (large business transaction)
| INR amount converted | Rs.1,00,00,000 |
| Taxable value (uncapped) | Rs.5,500 + (0.1% of Rs.90,00,000) = Rs.5,500 + Rs.9,000 = Rs.14,500 |
| Law cap on taxable value | Rs.60,000 (cap applies since Rs.14,500 < Rs.60,000 — cap not hit here) |
| GST at 18% | Rs.14,500 × 18% = Rs.2,610 |
| Total GST you pay | Rs.2,610 on Rs.1 crore import payment |
The cap of Rs.60,000 (max GST Rs.10,800) kicks in only when the transaction exceeds approx. Rs.65 crore in a single transaction.
GST on Different Types of Forex Transactions
The GST treatment changes depending on whether you are sending money out or receiving it, and whether you are an individual or a business. Here is a clear breakdown:
| Transaction Type | Direction | Who Does It | GST Applicable? | Rate / Notes |
|---|---|---|---|---|
| Buying foreign currency for travel | Outward | Individuals | Yes | 18% on slab value. Shown on invoice from AD bank / money changer. |
| Loading a forex card | Outward | Individuals | Yes | 18% on slab value. Same as buying currency. |
| LRS outward remittance (education, maintenance, travel) | Outward | Individuals | Yes | 18% on slab value. Separate from TCS — both apply independently. |
| Import payment (goods/services) | Outward | Businesses | Yes | 18% on slab value. ITC can be claimed if used for taxable supply. |
| Export receipt — inward remittance | Inward | Exporters (goods & services) | Zero-rated — No GST | Section 16 IGST Act. Exporter receives USD/EUR, bank converts to INR — no GST on conversion service for export receipts. |
| Freelancer / IT services receipt from abroad | Inward | Freelancers, IT companies | Zero-rated — No GST | Export of services. FIRC/eFIRA is proof. File LUT before invoicing. Do not charge GST on international invoice. |
| International credit card transactions abroad | Outward | Individuals | Yes | Bank charges forex markup + 18% GST on markup. Appears in monthly statement. |
| NRI sending money to India (NRO/NRE account) | Inward | NRIs | No GST | Inward remittance. Bank converts at prevailing rate. No GST on this service. |
GST and TCS: Two Different Taxes on the Same Transaction
This is where most people get confused. When you send money abroad under LRS, two completely separate taxes can apply — GST and TCS. They are governed by different laws and collected by different parties for different purposes.
| Feature | GST on Forex Service | TCS on LRS Remittance |
|---|---|---|
| What it taxes | The service of converting currency | The remittance amount itself |
| Legal basis | CGST Act + Rule 32(2) CGST Rules | Section 394, Income Tax Act 2025 |
| Rate | 18% on service value (very small) | 2% or 20% on amount above Rs.10 lakh |
| Threshold | Minimum GST = Rs.45 (no upper threshold below Rs.60,000 service value) | Rs.10 lakh per PAN per FY (no threshold for overseas tour packages) |
| Collected by | Bank/AD bank → remits to GST department | Bank/AD bank → remits to Income Tax department |
| Refundable? | Only for GST-registered businesses via ITC | Yes — for individuals via ITR as tax credit (Form 26AS) |
| Applies to | All forex transactions (buying, loading, remitting) | Outward LRS remittances only |
Can You Claim GST Back? ITC for Businesses vs Individuals
Individuals — No ITC, No Refund
If you are an individual converting currency for personal travel, education, or maintenance, the GST paid on forex services is a final cost. You cannot claim it back in your income tax return, and you cannot claim ITC because you are not a GST-registered entity making taxable supplies. The amount is small (typically Rs.45 to Rs.1,260 for most retail transactions), so the practical impact is limited.
GST-Registered Businesses — ITC Possible
If your business is GST-registered and you convert foreign currency for business purposes (paying an overseas vendor, import payments, business travel), you may be eligible to claim Input Tax Credit on the GST paid for the forex conversion service. The following conditions must be met:
- The AD bank or forex dealer must issue a proper GST tax invoice showing your company’s GSTIN
- The forex transaction must be for a business purpose, not personal
- The input (forex service) must be used to make taxable outward supplies
- The GSTR-2B must reflect the supplier’s filing
Always provide your company’s GSTIN to the bank at the time of the forex transaction to ensure the invoice is issued in the company’s name. An invoice in your personal name cannot be used to claim ITC for your company.
Exporters — Zero-Rated, Claim IGST Refund
If you are an exporter receiving foreign payment (inward remittance for export of goods or services), there is no GST on the inward conversion. This is a zero-rated transaction. Additionally, all GST paid on your business inputs (raw materials, services used to produce your exports) can be refunded by filing a refund claim under Rule 89 of CGST Rules. Maintain FIRC (Foreign Inward Remittance Certificate) or eFIRA for every export receipt as primary evidence.
Practical Scenarios: Real-Life GST on Forex Questions Answered
Scenario 1: A salaried person buys USD 2,000 for a USA holiday (Rs.1,70,000 approx.)
Slab: Rs.1 lakh to Rs.10 lakh. Service value = Rs.1,000 + 0.5% of Rs.70,000 = Rs.1,000 + Rs.350 = Rs.1,350. GST = 18% of Rs.1,350 = Rs.243.
✔ GST payable: Rs.243 only. Cannot be claimed back. Small, unavoidable cost of the transaction.
Scenario 2: A freelancer receives USD 5,000 from a US client for web design services
This is an inward remittance for export of services. The bank converts USD 5,000 to INR at the prevailing rate. The freelancer does not charge GST on the international invoice (export of services is zero-rated). No GST on the currency conversion service either. The freelancer must have filed a Letter of Undertaking (LUT) to claim zero-rated status and must collect the eFIRA from the bank.
✔ GST payable by freelancer: Nil. But LUT filing and FIRC collection are mandatory for compliance.
Scenario 3: An importer pays EUR 50,000 to a German supplier (approx. Rs.47,00,000)
The company converts Rs.47 lakh to EUR through their AD bank. Slab: Above Rs.10 lakh. Service value = Rs.5,500 + 0.1% of Rs.37,00,000 = Rs.5,500 + Rs.3,700 = Rs.9,200. GST = 18% of Rs.9,200 = Rs.1,656. Since the company is GST-registered and this is a business payment, they can claim Rs.1,656 as ITC — provided the bank issues the invoice with the company’s GSTIN.
✔ GST payable: Rs.1,656 — but recoverable as ITC for GST-registered importer.
Scenario 4: Parent remits Rs.18 lakh for child’s university fees in UK
Outward LRS remittance. Slab: Above Rs.10 lakh. Service value = Rs.5,500 + 0.1% of Rs.8,00,000 = Rs.5,500 + Rs.800 = Rs.6,300. GST = Rs.6,300 × 18% = Rs.1,134. Separately, TCS at 2% on Rs.8 lakh excess (education purpose) = Rs.16,000. Total deductions: Rs.1,134 GST (gone) + Rs.16,000 TCS (claimable in ITR).
✔ GST Rs.1,134 is a cost. TCS Rs.16,000 is recoverable via ITR as credit against income tax liability.
Common Mistakes That Cost People Money
Quick GST Checklist Before Any Forex Transaction
Before You Convert Foreign Currency — Check These
- Ask for a GST invoice from the bank or money changer. It is your legal right.
- Check that the invoice shows SAC Code 997153 and 18% GST rate.
- If you are a business — give your GSTIN before the transaction, not after.
- Verify the taxable value on the invoice matches the slab calculation (check the examples above).
- If you are an exporter receiving payment — ask the bank for the eFIRA within 15 days of credit.
- If you are a freelancer invoicing a foreign client — do not add GST. File your LUT first.
- Keep all forex GST invoices for at least 6 years (GST audit period).
- Do not confuse TCS deduction with GST. Check your bank debit advice for both line items separately.
