GST on Services vs Goods: What Actually Changes

GST is meant to be one tax across goods and services — and in its structure it largely is. But the moment you get into the day-to-day, goods and services behave differently in ways that matter for your invoices, your tax type, and your compliance load. The rates differ, the classification codes differ, the rules for where a supply happens differ, and one whole obligation — the e-way bill — applies to goods alone. If you sell both, or if you have always done one and are starting the other, knowing these differences prevents wrong invoices and the credit mismatches they cause downstream. This article lays out exactly what changes, with examples and a worked illustration.

Where goods and services are treated the same

Before the differences, the common ground — because most of GST does not care whether you sell a product or a service:

• One registration covers both goods and services under a single GSTIN.
• The same returns apply — GSTR-1 for outward supplies and GSTR-3B for the summary and payment, regardless of what you sell. The mechanics are covered in GST Returns for Beginners.
• Input tax credit works the same way conceptually — you offset GST paid on inputs against GST collected on outputs (subject to the usual conditions), whether your output is a good or a service. See Input Tax Credit Explained.
• The CGST + SGST / IGST split logic is identical: intra-state supplies carry CGST + SGST; inter-state supplies carry IGST.

So the framework is shared. What differs are four specific things: the rate, the code, the place-of-supply rule, and the e-way bill. Let us take each.

Difference 1: Rates

The most visible difference is rates.

Services mostly sit at a standard 18%. For a large share of professional, consulting, agency, IT, and business services, 18% is the rate — and a reasonable default assumption when you start. That said, services are not uniformly 18%: some are exempt or nil-rated (certain healthcare and education), some attract 5% or 12% (certain transport and specified services), and a few attract more. The rule of thumb is "assume 18% for a typical service, but confirm for yours."

Goods are spread across multiple slabs. Products commonly fall into 5%, 12%, 18%, or 28%, depending on the item — essentials and many food items at lower rates, standard goods in the middle, and certain categories at the top slab. There is far more variation across goods than across services, which is why goods sellers must be more careful about getting each product's rate right.

Aspect	Services	Goods
Typical/standard rate	18% (common default)	Varies by item
Range of slabs	Some 5/12, mostly 18, few higher; some exempt	5%, 12%, 18%, 28%
Rate variation	Lower — many services cluster at 18%	Higher — depends heavily on the product
Classification code	SAC	HSN

This single difference explains why a consultant rarely agonises over their rate (it is usually 18%), while a trader dealing in dozens of products must map each one to its correct slab.

Difference 2: HSN versus SAC codes

Every GST invoice carries a classification code, and the code differs by what you sell.

• Goods use HSN codes (Harmonised System of Nomenclature). Each product maps to an HSN code, and the code ties to the rate schedule that fixes its GST rate.
• Services use SAC codes (Services Accounting Code). Each service maps to a SAC code.

If you sell only goods, you quote HSN; only services, you quote SAC; both, you use both. The number of digits you must report can depend on your turnover, so check the current digit requirement on the GST portal — but the principle never changes: goods = HSN, services = SAC.

Getting the code right is not a formality. The code underpins the rate and the classification in your returns, and a wrong code can mean a wrong rate, which cascades into your customer's credit. For service providers raising invoices, the correct SAC and tax split are part of getting the invoice right — see Freelancer Invoice and the broader GST for Small Business primer.

Difference 3: Place of supply

This is the most consequential difference, because it decides whether you charge CGST + SGST or IGST — and charging the wrong one disrupts your customer's input tax credit.

Place of supply is the rule that locates a transaction. If the place of supply is in your own state, it is intra-state (CGST + SGST); if it is in another state, it is inter-state (IGST).

• For goods, the place of supply generally follows where the goods move — broadly, where delivery terminates or where the movement ends. Ship goods to a buyer in another state and it is an inter-state supply attracting IGST.
• For services, the default is often the location of the recipient — particularly for registered recipients — but there is a substantial list of specific exceptions. Services connected to immovable property (the property's location governs), event-based services, transportation, restaurant and certain on-site services, and others each follow special place-of-supply rules.

The practical risk is the same in both cases: misjudging place of supply means charging the wrong tax type. If you charge CGST + SGST when it should have been IGST (or vice versa), your customer receives the wrong kind of credit and cannot offset it cleanly, generating notices and adjustments. Always determine the place of supply before finalising the invoice — check the recipient's registered location for services, and the delivery destination for goods.

Difference 4: The e-way bill

Here the difference is absolute. The e-way bill — required broadly when goods worth over Rs.50,000 are moved — applies only to the movement of goods. Services involve no physical consignment, so a service never needs an e-way bill.

If your business is purely services, the entire e-way bill system is irrelevant to you. If you sell goods, the e-way bill becomes part of dispatch whenever the threshold is crossed. And if you supply both, only the goods leg can trigger the obligation. The full mechanics — threshold, validity, who generates it — are in E-Way Bill Explained. The takeaway here is simply that this is one obligation goods sellers carry and service providers do not.

A note on the registration threshold

The differences extend to registration. The commonly cited threshold is Rs.20 lakh of aggregate turnover, but two qualifications matter:

• A lower Rs.10 lakh threshold applies for certain special-category states.
• A higher threshold for businesses dealing exclusively in goods applies in some cases (notified at a higher turnover for goods-only suppliers in eligible states), while the lower limit applies to service providers.

So a goods-only trader and a service provider in the same state can face different registration thresholds. Because these limits are revised and have state-specific variations, confirm the current threshold for your situation on the GST portal rather than assuming a single number. For those below the threshold or with simple operations, the GST Composition Scheme is a lighter alternative — though it too treats goods and service eligibility differently.

A worked example in rupees

Consider Nirvana Studio, a Karnataka business that does two things: it designs interiors (a service) and sells furniture (goods).

The service side — an interior-design project for a Bengaluru client (same state):

• Design fee: Rs.2,00,000
• GST on services at 18%: Rs.36,000 (CGST 9% Rs.18,000 + SGST 9% Rs.18,000, because it is intra-state)
• Invoice carries the relevant SAC code; no e-way bill (it is a service)
• Place of supply: the client's location in Karnataka → intra-state → CGST + SGST

The goods side — selling furniture to a client in Tamil Nadu (different state):

• Furniture value: Rs.3,00,000
• Assume the applicable furniture rate is 18% (confirm the actual HSN rate): Rs.54,000 IGST (inter-state, so IGST not CGST/SGST)
• Invoice carries the relevant HSN code
• Because the goods value exceeds Rs.50,000 and they cross a state border, an e-way bill is required for this consignment
• Place of supply: where the goods are delivered, Tamil Nadu → inter-state → IGST

Notice how a single business, on a single day, applies two codes (SAC and HSN), two place-of-supply logics, and an e-way bill on the goods leg only. Both transactions go into the same GSTR-1 and GSTR-3B, but they are built differently. Computing the combined liability is straightforward once each leg is correct — a GST calculator confirms the figures, and a GST tracker keeps the goods and service invoices reconciled for filing.

Mixed supplies: when goods and services come together

A practical wrinkle: sometimes a single supply bundles goods and services — and GST has concepts for this. A composite supply is a natural bundle where one element is principal (the whole is taxed at the principal element's rate), while a mixed supply of items bundled together for a single price is taxed at the highest applicable rate among them. Works contracts and restaurant supplies are classic examples treated under specific rules.

You do not need to master every nuance, but you should recognise when a sale is a bundle, because the rate of the bundle may not be the rate of its cheapest component. When a supply genuinely combines goods and services, check how it is classified before pricing it — it affects both your rate and your margin, a link worth seeing through a profit margin lens.

Common mistakes

• Assuming every service is exactly 18%. Most are, but some are exempt, 5%, or 12% — confirm for your specific service.
• Putting an HSN code on a service (or a SAC on goods). Goods = HSN, services = SAC; swapping them is a classification error.
• Getting place of supply wrong. Charging CGST + SGST when IGST applies (or vice versa) breaks your customer's credit and invites notices.
• Forgetting that services need no e-way bill. Generating one for a service signals confusion about the supply type.
• Generating no e-way bill on a goods consignment over Rs.50,000. The goods leg of a mixed business still carries this obligation.
• Assuming a single registration threshold. Goods-only and service businesses can face different thresholds, and special-category states differ.
• Mispricing a bundled supply. A mixed supply can be taxed at the highest component rate; assuming otherwise erodes margin.
• Using a memorised rate for goods. Goods rates vary widely by item; verify each product's HSN rate rather than guessing.

What to do next: a checklist

• Identify whether you supply goods, services, or both — this drives everything below.
• For services, default to 18% but confirm the rate for your specific service.
• For goods, map each product to its HSN code and current rate — do not assume one rate fits all.
• Put the correct code on every invoice: HSN for goods, SAC for services.
• Determine place of supply before invoicing — recipient location for services (with exceptions), delivery destination for goods.
• Apply e-way bill rules to the goods leg only, when value exceeds Rs.50,000.
• Confirm the registration threshold that applies to you, noting goods/service and special-state differences.
• For bundled supplies, check the composite/mixed classification before pricing.
• Reconcile both goods and service invoices in a single GST tracker and verify totals with a GST calculator.

The structure of GST is shared across goods and services, but the operational details — rate, code, place of supply, and e-way bill — are where the two part ways. Know those four differences, apply the right one to each transaction, and a mixed goods-and-services business files just as cleanly as a single-line one.
