01What the bill is made of
Two different suppliers bill you for one campaign. The ad platform charges for the media — the impressions and clicks you bought. Whoever builds and runs the campaign charges a service fee. Both are taxable supplies, invoiced separately, on different dates, by different entities.
Advertising services are taxed at the standard GST rate of 18%. Rates, service classifications and who is liable to pay are your accountant's call, not ours — but the shape of the bill does not change: media spend, service fee, tax on each.
So when someone says a campaign costs ₹50,000 a month, the honest number is larger, and how much larger depends on a question most businesses have not answered yet: are you registered under GST.
02Whose invoice you get, and why it matters
This is the part that decides what you can do with the tax you paid, and it is set by account configuration rather than by preference.
- Ad platform. On Google Ads, the billing country and currency are fixed when the account is created and cannot be switched later — so an account set up in the wrong country is a permanent problem, not a settings change (Google's own payment documentation). Meta describes adding your GSTIN to the billing setup so the monthly invoice carries your tax details (Meta's help page on GST for India).
- Agency or freelancer. Their fee is a separate Indian service invoice, carrying their GSTIN, and only if they are registered. Ask for the invoice format before signing, not after.
- Anything else in the stack. Hosting, a domain, tools, stock photo subscriptions — many are billed by foreign entities. Those have their own GST treatment, and it is the same question: who invoiced you, and from where.
03When the credit is claimable
Input tax credit is not a rebate that arrives; it is a set-off against GST you owe on your own taxable sales. In practice, four things have to be true before anyone can claim it:
- The business is registered under GST.
- The invoice is a tax invoice in the business's name, carrying its GSTIN, with the tax shown separately.
- The supplier has reported and paid that tax.
- The business charges GST on what it sells, so there is an output liability to set the credit against.
If the business is not registered — below the threshold, or selling things that are exempt — there is no credit to claim and the GST is simply part of the cost of advertising. If the credit cannot be claimed, a ₹50,000 media budget is a ₹59,000 cost before anyone's fee.
Where the invoice comes from outside India, the tax question becomes an import of services, and liability can fall on the recipient rather than the supplier. Whether a particular bill lands that way depends on which entity actually invoiced you — which is exactly the question to put to a chartered accountant, in writing, with the invoice attached.
04Four questions to sort before the first campaign
- Are we registered under GST? It decides whether the tax is recoverable or a cost.
- In whose name is the ad account, and which country is it billed in? Ask whoever sets it up to show you, not to promise.
- Will the invoices carry our GSTIN? Every month, from every supplier, or the credit is not claimable.
- Can our accountant see the ad invoices monthly? The people who get this wrong do it once a year, at filing time.
None of these are hard. All of them are cheaper to ask before the money moves than after.
05Questions people ask us
Does paying in dollars avoid the tax?
No. Currency is a billing setting, not a tax position. If the supply is treated as an import of services, GST is still in play, and switching a Google Ads account to dollars after the fact is not possible anyway.
Is GST charged on the media budget or on your fee?
Both, separately. The platform bills the media with its own tax line; we bill the service fee with ours. Knowing which invoices are coming, and from whom, is the difference between a clean file and an argument.
Can a small business with no GST registration claim it back?
Not through GST. Unregistered, there is no output liability to set the credit against, so the tax is a cost of the channel. That is a reason to plan the budget at 18% above media, not a reason to skip it.
The platform invoice does not have our GSTIN. Fixable?
Usually yes, going forward. Add the GSTIN to the billing setup and ask for a corrected or fresh invoice for the period. Back-dated tax invoices are the accountant's problem to judge, not ours.
Do you handle the GST side?
We get the setup right and hand you the invoices — the tax position is yours and your accountant's. Anyone who wants to advise you on your GST from inside a media plan is doing two jobs, and usually one of them badly.
06Where this fits
Billing country and account ownership belong to the same conversation as Google Ads setup — that page covers who holds the payment method and what happens to the account later. The media side of the same invoice is Meta Ads, and the fee side is whatever engagement you agree. If the paperwork is the thing standing between you and a campaign, ask us — it is a fair first question. The other two guides pick up from here: local services covers what to run when the area is narrow, and leads without orders covers what to fix once enquiries arrive.
