GST on Home Interiors: 18% or 12%, and What Belongs on Your Invoice
Two GST rates float around interior quotes in Bengaluru — 18% and 12% — and the difference is not a discount, it is a classification. This guide settles which rate applies to what, why homeowners cannot claim input tax credit, how GST should appear on a clean quote, and what a missing bill really tells you about the materials going into your home.
Is GST on home interiors 18% or 12%?
Quick answer
Both rates genuinely exist, which is why the confusion persists. A turnkey interior works contract — design, material and installation supplied together — attracts 18% GST. Some unbranded custom furniture items can fall at 12%. The rate depends entirely on what is actually being supplied.
If you have collected three quotes in Bengaluru, you may have seen 18% on one, 12% on another, and no tax line at all on the third. None of that necessarily means anyone is cheating — but it does mean the three firms are describing your project differently, and only one description usually fits a full-home interior.
A turnkey interior project — where one firm designs, supplies material and installs it in your home as a single scope — is a works contract, and works contracts carry 18% GST. That is the rate that applies to the way most Bengaluru homes actually get done: kitchen, wardrobes, ceiling, painting and installation under one agreement.
The 12% figure is not a myth either. Some unbranded custom furniture items can fall at 12% — and this single fact is the source of most homeowner confusion. The classification turns on what is being supplied, not on which number sounds better in a sales conversation.
Why do two firms quote different GST rates for the same home?
Quick answer
Because GST classification follows the supply, not the room. A firm delivering a turnkey works contract charges 18%. A vendor selling you an unbranded custom furniture item may legitimately be at 12%. Same wardrobe, different supply structure — so the tax line looks different.
The rate on your quote is determined by what the seller is legally supplying to you. When a studio contracts to design and build your whole home — measuring the site, fabricating units, installing them, handing over a finished space — that bundle is a works contract at 18%. When a furniture maker sells you a standalone unbranded custom piece, that item may sit at 12%.
This is why comparing quotes purely on the tax line is a mistake. A 12% rate is not automatically a saving, and an 18% rate is not automatically padding — they can both be correct for the supplies they describe. What should concern you is a firm quoting a full turnkey scope while showing a rate that belongs to a different kind of supply, or a rate that shifts between the first estimate and the final bill without the scope changing.
If a rate looks unusual for the scope, ask the firm to state in writing what is being supplied and why that rate applies. A legitimate operator can answer in one line. Evasion on this question is information in itself.
Can you claim input tax credit on your home interiors?
Quick answer
No. Homeowners are end consumers, and end consumers cannot claim input tax credit on home interiors. The GST on your project is a final cost to you, which is exactly why it should be visible as its own line rather than buried inside item rates.
Input tax credit is the mechanism that lets businesses offset the GST they pay on inputs against the GST they collect on outputs. As a homeowner furnishing your own residence, you are the end of that chain — the GST on your interiors is not recoverable, whatever anyone at a sales table implies.
This has a practical budgeting consequence. Since the tax is a real, final cost, it belongs in your project maths from day one. Typical Bengaluru market ranges are quoted excluding GST — a full 2BHK at ₹8–14 lakh essential, a 3BHK at ₹12–18 lakh essential — so the tax comes on top of those figures, not inside them. A quote that hides the tax inside item rates makes your project look cheaper than it is until the final bill arrives.
It also means no honest firm can offer you a 'GST saving' on a turnkey home. The rate is what the classification says it is, and you cannot claim it back. Any pitch built around making the tax disappear should sharpen your attention on everything else in that quote.
How should GST appear on a legitimate interiors quote?
Quick answer
As a separate, transparent line — the rate stated, applied on top of clearly itemised base prices. A legitimate firm bills GST this way as standard practice. A lump-sum figure with no visible tax treatment tells you the quote is hiding structure you will pay for later.
The cleanest quotes in this market share one habit: every item is priced excluding GST, and the tax appears as its own line at the end, with the rate named. You can see the base cost of the work, you can see the tax, and you can verify the arithmetic yourself. AesthetiX publishes all rates exclusive of GST and bills it as a separate line for exactly this reason — the practice is the transparency.
The opposite pattern is the all-inclusive lump sum: one number, 'taxes included', no break-up. It feels simpler, but it removes your ability to check anything — you cannot tell what the work costs, what the tax is, or whether the rate applied matches the supply. Lump-sum pricing is also the structure under which silent substitutions and quote escalations travel undetected, because no individual line exists to hold anyone to.
When you compare quotes, normalise them first: strip every quote back to its ex-GST base and confirm each firm's tax treatment in writing. Two quotes that look far apart can converge — or swap places — once the tax lines are made comparable.
What does a missing GST bill tell you about your materials?
Quick answer
Usually that the material is counterfeit. No legitimate brand sells genuine materials without a GST invoice. A vendor offering plywood, laminates or hardware 'cheaper without the bill' is not saving you tax — the bill is missing because the brand on the box is not real.
This is the point where GST stops being an accounting topic and becomes a material-quality check. Genuine branded materials travel with GST invoices — that is how legitimate supply chains work. When a site supervisor or vendor offers to source material without a bill at a better price, the discount is not a tax dodge on your behalf. It is the price signature of counterfeit stock.
The bill matters again years later. A written BOQ backed by material bills is what wins if a project ever ends up in dispute — dissatisfaction alone does not. A missing invoice today is a missing defence tomorrow.
So make GST invoices for materials a standing demand on your project, not a favour. Ask to see them at delivery, match brand and grade against your BOQ, and keep them with your project file. A firm that resists producing material bills is telling you what is actually arriving on site.
How do you actually read the tax lines of a quote?
Quick answer
Check four things: base prices itemised and marked excluding GST, the tax as a separate line with the rate stated, a rate that matches the supply — 18% for a turnkey works contract — and GST invoices promised for materials. A quote failing these checks costs more than it shows.
Take five minutes with the last page of every quote you receive. The tax treatment is one of the fastest honesty tests available to you, because it is binary: either the structure is visible or it is not.
A quote that passes all four checks below is not automatically the right quote — but a quote that fails them is telling you, in advance, how the project will be run.
- Normalise every quote to its ex-GST base before comparing firms
- Get the applied rate and its basis stated in writing before paying any booking amount
- File material GST invoices with your BOQ — they are your warranty and dispute evidence
| Check | What a clean quote shows | What should worry you |
|---|---|---|
| Base pricing | Itemised lines, each marked excluding GST | A single all-inclusive lump sum with no break-up |
| Tax line | GST as its own separate line, rate stated | Tax buried inside item rates or absent entirely |
| Rate vs supply | 18% on a turnkey works contract | An unexplained rate, or one that changes between estimate and final bill |
| Material bills | GST invoices committed for branded materials | Materials offered 'cheaper without the bill' |
The rate follows the supply: turnkey works contracts attract 18% GST; some standalone unbranded custom furniture can fall at 12%.
