Digital advertising on Google and Meta platforms is a primary marketing expense for Indian businesses. Claiming input tax credit (ITC) on these spends requires verifying the legal contracting entity on the invoice. Depending on whether you are billed by an Indian entity or an overseas entity, the compliance route under GST law is completely different.
Two billing models: domestic billing versus foreign billing
Before claiming credit in Form GSTR-3B, inspect the header and tax details of your advertising invoice. Ad platforms bill Indian accounts through one of two structures:
- Domestic Indian entity: Billed by an entity registered under GST in India, such as Google India Private Limited. The invoice includes Indian GST (18% IGST or 9% CGST + 9% SGST) and displays the supplier GSTIN along with your GSTIN.
- Overseas entity: Billed by an overseas corporate office, such as Meta Platforms Ireland Limited or Google Asia Pacific Pte. Ltd. (Singapore). The invoice charges 0% GST or zero-rated tax because the supplier is outside India.
Common mistake: Treating an overseas invoice as a domestic purchase. If your invoice is from an entity outside India with no GST charged, you cannot take credit directly in Table 4(A)(5). Doing so without discharging reverse charge tax creates unpaid tax liability under Section 5(3) of the IGST Act.
Domestic billing: matching invoices in GSTR-2B
When billed by an Indian entity, credit eligibility follows standard input tax rules under Section 16(2) of the CGST Act. To claim credit:
- You must hold a valid tax invoice with your GSTIN under Section 16(2)(a).
- The ad service must be received and used in the course or furtherance of business under Section 16(1).
- Under Section 16(2)(aa), the supplier must file Form GSTR-1, and the invoice details must be communicated to you in Form GSTR-2B.
If you fail to add your business GSTIN in your Google Ads or Meta Ads billing profile, the platform treats your account as an unregistered B2C consumer. In that case, the supplier files the transaction in Table 7 (B2C supplies) of GSTR-1, no credit flows to your GSTIN, and the ITC is lost.
Foreign billing: reverse charge on import of services
When the invoicing entity is located outside India, the transaction is treated as an import of services. Under Section 2(11) of the IGST Act, an import of services occurs when:
- The supplier of service is located outside India;
- The recipient of service is located in India; and
- The place of supply of service is in India.
Under Entry 1 of Notification No. 10/2017-Integrated Tax (Rate), any service supplied by any person located in a non-taxable territory to any person other than a non-taxable online recipient (NTOR) is taxable on reverse charge basis under Section 5(3) of the IGST Act. As a GST-registered business receiving digital advertising services, you are liable to pay the tax.
How to report foreign ad invoices in Form GSTR-3B
According to the GST portal guidelines on Form GSTR-3B Table 4 structure, follow these reporting steps:
- Discharge tax in cash: Declare the taxable value and 18% IGST under Table 3.1(d) (Inward supplies liable to reverse charge). Pay this liability using your electronic cash ledger. You cannot set off reverse charge liability against existing ITC balances.
- Avail input tax credit: In the same tax period, claim the integrated tax paid as credit under Table 4(A)(2) (Import of services).
Worked example: domestic billing versus foreign billing
Consider an Indian business spending ₹1,00,000 on digital marketing across two platforms in a tax period. The business verifies invoices and discharges liabilities as follows:
| Platform & Entity | Invoice Value | Tax Mechanism | Tax Payable | ITC in GSTR-3B |
|---|---|---|---|---|
| Google India (Domestic) | ₹60,000 | Forward charge (18% IGST) | ₹0 (Paid to vendor) | ₹10,800 in Table 4(A)(5) |
| Meta Ireland (Foreign) | ₹40,000 | Reverse charge (18% IGST) | ₹7,200 in Cash (Table 3.1(d)) | ₹7,200 in Table 4(A)(2) |
Calculation details:
- Google India invoice: Taxable value = ₹60,000. IGST at 18% = ₹10,800 (Formula: 60,000 × 18 / 100). Vendor files GSTR-1, invoice reflects in GSTR-2B, and credit is availed in Table 4(A)(5).
- Meta Ireland invoice: Taxable value = ₹40,000. Under RCM, IGST at 18% = ₹7,200 (Formula: 40,000 × 18 / 100). The business pays ₹7,200 in cash under Table 3.1(d) and claims ₹7,200 ITC under Table 4(A)(2).
Step-by-step checklist for claiming ad spend ITC
- Update platform tax settings: Log into your Google Ads and Meta Business Suite accounts. Add your registered GSTIN, correct legal trade name, and Indian registered office address.
- Download monthly tax invoices: Do not rely on credit card charge slips or summary receipts. Download official monthly statements marked as Tax Invoice.
- Verify GSTR-2B: For Indian billing entities, confirm that the supplier GSTIN and invoice appear in your GSTR-2B for the respective tax period.
- Pay RCM for foreign invoices: If billed by an overseas entity, compute 18% IGST, report under Table 3.1(d), pay via electronic cash ledger, and avail ITC under Table 4(A)(2).
Frequently asked questions
Can I claim ITC on Google Ads if my GSTIN is missing from the invoice?
No. Under Section 16(2)(a) and Rule 36(1) of the CGST Rules, a valid tax invoice with your GSTIN is mandatory. If you do not add your GSTIN to your billing profile, the platform issues a B2C invoice and does not report it against your GSTIN in GSTR-1, so it cannot appear in your GSTR-2B.
How do I claim ITC when billed by Meta Ireland under reverse charge?
When billed by a foreign entity, the transaction is an import of services under Section 2(11) of the IGST Act. You must report and pay 18% IGST under reverse charge in Table 3.1(d) of Form GSTR-3B using cash ledger funds. You then claim ITC in Table 4(A)(2) of the same return.
Can I pay reverse charge tax on foreign ad invoices using existing input tax credit?
No. Reverse charge liability cannot be settled by utilising input tax credit. It must be discharged in cash through the electronic cash ledger. Once paid, the tax becomes available as input tax credit in Table 4(A)(2) of Form GSTR-3B.
Reconcile marketing invoices in your GSTR-2B
Verify whether domestic ad invoices from Google India or digital marketing agencies reflect in your auto-drafted GSTR-2B. Your GSTR-2B and purchase register files are read in your browser and never uploaded to any server.
