GST on Google & Meta Ads: How RCM Applies to Digital Marketing

Digital Advertising & RCM

If you pay Google Asia Pacific (Singapore) or Meta Platforms Ireland for business advertisements using an Indian credit card, you must pay 18% IGST on reverse charge. These companies do not charge Indian tax on business accounts that provide an active GSTIN. It is your responsibility to self-assess the tax and claim ITC, completing the compliance loop.

Self-Invoicing Requirement

Create a self-invoice for each month''s billing statements, charging yourself the 18% IGST. Declare this liability under GSTR-3B table 3.1(d) and claim the matching input tax credit in table 4(A)(3) of the same return. Check the meta-ads specific guide to learn about address layouts.

Failing to pay the RCM tax triggers interest liabilities at 18% per year under GST Section 50.

Statutory Compliance & GST Export Framework

Under Section 16 of the Integrated Goods and Services Tax (IGST) Act, 2017, export transactions are categorized as Zero-Rated Supplies. This legal position allows exporters to conduct business operations without tax liability. However, to maintain this tax-exempt status, businesses must adhere strictly to the rules laid down in Rule 96A of the CGST Rules, 2017. Under this rule, you must either export under a Letter of Undertaking (LUT) in Form GST RFD-11 or pay the applicable integrated tax (IGST) upfront and later claim a refund of the paid tax. Read more on filing and invoicing in our LUT Witness & Invoice Setup Guide.

Filing the Letter of Undertaking (LUT) is a mandatory step that must be completed prior to the commencement of export operations for each financial year. Exporters often make the mistake of issuing invoices with zero tax before filing the LUT. This omission is flagged during tax audits, resulting in demand notices from the department. The LUT is valid only for a single financial year (from April 1 to March 31), and a fresh application must be submitted online on the official GST Portal (gst.gov.in) at the start of every new fiscal period to prevent compliance disruptions.

Additionally, the place of supply for cross-border services must be determined in accordance with Section 13 of the IGST Act. In most cases involving remote consultancy, software development, and digital marketing, the Place of Supply is the location of the recipient outside India. However, if the services are classified as intermediary services (where the exporter merely facilitates a supply between two parties), the Place of Supply shifts to India, making the transaction subject to 18% IGST. Understanding this distinction is vital for digital agencies to avoid audit assessments, as discussed in our analysis of the GST Place of Supply rules.

Step-by-Step GST Portal Navigation for RFD-11

To file the Letter of Undertaking on the GST portal, follow this precise navigation pathway:

1. Log into the GST Portal using your registered tax credentials.
2. Navigate to the top menu and select Services > User Services > File LUT (RFD-11).
3. Select the correct Financial Year for which you are submitting the LUT from the drop-down menu.
4. If you have previously filed an LUT for the prior financial year, upload the previous LUT ARN receipt as supporting evidence.
5. Fill in the declaration check-boxes confirming that you will realize export proceeds within the mandated timeline.
6. Enter the details (Name, Address, PAN, and signatures) of two independent witnesses. Ensure their details match their official tax records. You can download the template from our LUT Witness affidavit guide.
7. Sign the application using your Digital Signature Certificate (DSC) or through Electronic Verification Code (EVC) OTP, then click submit.

Once submitted, the portal will generate an Application Reference Number (ARN) receipt. You must print this ARN number on all your commercial export invoices to satisfy customs and bank compliance officers during audits.

Reverse Charge Mechanism (RCM) & SaaS Import Rules

Under Section 9(3) and 9(4) of the CGST Act, 2017, the liability to pay GST shifts from the supplier to the recipient in specific transactions. This is known as the Reverse Charge Mechanism (RCM). When an Indian business imports services from an overseas provider (such as Slack, GitHub, Amazon Web Services, or OpenAI), the foreign vendor does not charge Indian GST. Instead, the importing business in India must self-assess the 18% IGST and pay it to the government. Read our Startup RCM Checklist.

A common mistake made by startups and digital agencies is failing to declare and pay RCM on foreign SaaS tool purchases. During audits, tax officers review bank statements and credit card logs to identify payments made to overseas entities. If they detect non-payment of RCM, they issue notices demanding the tax amount plus 18% interest under GST Section 50. Paying the RCM tax is mandatory even if the business is eligible to claim the paid amount back as Input Tax Credit (ITC), as explained in our Google & Meta Ads RCM Guide.

Under GST rules, the recipient of RCM services must issue a **Self-Invoice** under Section 31(3)(f) of the CGST Act. The self-invoice details the supplier's address, transaction value, and the applicable IGST rate. Once the tax is paid in the monthly GSTR-3B return, the business can claim the matching input credit in Table 4 of the same return, completing the compliance loop.

Step-by-Step RCM Reporting in GSTR-3B

To declare and reconcile RCM payments in your monthly GSTR-3B return, complete these steps:

1. Reconcile credit card statements and bank wires to identify payments made to foreign software or service providers.
2. Generate self-invoices for each RCM transaction and charge the 18% IGST.
3. Declare the total RCM taxable value and IGST liability in Table 3.1(d) (Inward supplies liable to reverse charge) of GSTR-3B on the GST Portal.
4. Pay the tax amount using the cash ledger (RCM liabilities cannot be settled using input tax credits).
5. Claim the paid IGST as Input Tax Credit in Table 4(A)(3) (Inward supplies liable to reverse charge) of the same return.
6. Ensure all entries match your purchase ledger to pass GSTR-9 annual audits.

FEMA & RBI Regulatory Inward Remittance Guidelines

The Foreign Exchange Management Act (FEMA) regulates all cross-border transactions in India. The Reserve Bank of India (RBI) mandates that all export proceeds, including earnings from software development, SaaS sales, and consulting services, must be repatriated to India within a strict timeline (currently nine months for goods and services). Failing to bring foreign currency into your local bank account inside this window constitutes a severe foreign exchange violation, subject to significant penalties from the RBI. Read the details in our FEMA 2026 consolidation guidelines.

When foreign exchange is received in India, the Authorized Dealer Category-I (AD Cat-I) bank is responsible for reporting the transaction to the RBI. This reporting relies on selecting the correct FEMA Purpose Code. The purpose code classifies the nature of the transaction (e.g., P0802 for software implementation services, P0807 for data hosting, and P1006 for general business support services). Mismatches between your invoice description and the selected banking purpose code will cause transaction holds or trigger scrutiny during tax reviews. Check the correct codes in our Freelance Purpose Codes Guide.

Furthermore, payment aggregators like Stripe, Wise, and PayPal process transactions through partner banks in India, which generate electronic Foreign Inward Remittance Advices (e-FIRAs). Exporters must actively download these advices to prove the source of funds during GST audits. FiscLane provides automated reconciliation dashboards to match banking remittance details with commercial invoices, making it easy to spot errors before they result in compliance failures. Learn more in our Wise & Stripe e-FIRA download walkthrough.

FEMA Compliance Checklist for Service Exporters

To ensure full compliance with FEMA and RBI regulations, service exporters should follow this verification checklist:

• Verify Purpose Codes: Confirm that the banking remittance profile uses the correct purpose code corresponding to the services detailed in client agreements.
• Realization Timeline: Track payment collection dates to ensure all foreign invoices are settled within the nine-month FEMA window.
• Download e-FIRAs: Download the electronic FIRA/FIRC documents from your payment processor within 15 days of settlement.
• EEFC Account Utilization: Open an Exchange Earners Foreign Currency (EEFC) account to hold foreign currency and avoid daily conversion losses.
• FDI Reporting: Ensure any foreign equity investments are reported on the official RBI FIRMS Portal (firms.rbi.org.in) within 30 days of share allotment.
