# Engineering Research under SAC Code 998112

Part of [SAC 9981: Research & development services](https://busy.in/sac-code-9981/).

Engineering Research And Development services allow businesses to use specialised resources or knowledge without owning them fully. In day to day work, clients pay a fee or royalty so that they can access these rights or research outputs for their own projects, products or operations.

SAC 998112 is used when the main service is research and experimental development services in engineering and technology, covering design, testing and improvement of products and processes. In simple terms, this code applies where the core agreement is about giving permission or carrying out focused research instead of selling physical goods.

In real life, these services are common in areas like R&D services in engineering and technology for applied industrial solutions. Using the correct SAC 998112 under GST helps both service providers and clients keep invoices clear and GST treatment consistent.

## 998112 SAC Code GST rate

From a GST point of view, engineering research and development fees are treated as supply of services. The taxable value usually includes upfront licence fees, recurring royalties, minimum guarantee amounts, renewal charges and any related service or support fees that form part of the same agreement.

After the September 2025 GST revision, most licensing and research based professional services that do not have any special notification continue to fall under the standard 18% slab. Registered business recipients can generally claim input tax credit when these services are used for making taxable supplies, subject to normal ITC conditions.

**The table below gives the prevailing standard GST rate for SAC code 998112.**

| SAC code | Description | New GST rate (from 22 Sep 2025) | Old GST rate (till 21 Sep 2025) | Notes |
| --- | --- | --- | --- | --- |
| 998112 | Research and experimental development services in engineering and technology | 18% with ITC | 18% with ITC | Similar to 998111, R&D services in engineering and technology are charged at 18% with ITC. The 56th meeting rationalisation does not carve out any special lower rate or exemption for these codes, so 18% continues. |

In practice, service providers who offer engineering research and development should apply 18% GST on the taxable value, quote SAC 998112 on tax invoices and keep the same classification in their GST records so that billing and input tax credit remain simple to review.

## Practical classification guidance

When selecting a code from the 9981 family, businesses should choose the SAC that best describes the central activity, whether it is engineering research and development or some other related service in the same group. Correct use of the six digit SAC and GST rate in % helps avoid disputes, keeps pricing transparent and makes input tax credit planning easier for both sides.

## Conclusion

SAC 998112 is meant for engineering research and development where clearly defined rights or research work are supplied in return for a fee or royalty. These services are generally taxed at 18% under GST, with ITC normally available to eligible registered recipients when they use the service for taxable business activities. By classifying bills under SAC 998112 and applying the correct GST rate in %, businesses can keep their contracts, invoices and GST compliance neat and easy to support during reviews or audits.

## Frequently asked questions

### What is SAC code 998112 in GST for engineering research?

SAC 998112 covers research and experimental development services in engineering and technology. It includes industrial R&D for new products, processes, prototypes and system designs, usually aimed at practical application in manufacturing, infrastructure or technology businesses, rather than purely academic or theoretical work.

### Does SAC 998112 cover industrial and engineering R&D services for product development?

Yes. When firms or institutes carry out engineering design studies, prototype building, performance tests and optimisation trials for future products or production lines, those services normally fall under SAC 998112. This may involve mechanical, electrical, electronics, civil or multi disciplinary engineering research focused on usable outcomes.

### What GST rate applies to engineering research services under SAC 998112?

Engineering research services under SAC 998112 are generally taxed at 18%. GST is charged on R&D contracts, development retainers and milestone based payments. If the project is specifically covered by any governmental incentive scheme, parties should examine whether special GST treatment or refunds apply in that context.

### Should engineering design and testing projects be billed using SAC 998112?

Yes. Projects where the main objective is to create or validate new engineering designs, systems or prototypes usually use SAC 998112. Routine quality control testing may fall under testing SAC codes instead. Clear scope documents help decide whether a project is experimental R&D or regular engineering service.

### Can manufacturers claim ITC on GST paid for SAC 998112 services?

Manufacturers can normally claim ITC on GST paid for SAC 998112 services when these R&D activities help develop or improve products that will be sold with GST. If research supports exempt output or non business activities, ITC will be restricted. Linking R&D projects to future taxable supplies is important.
