# Geological Consulting under SAC Code 998341

Part of [SAC 9983: Professional, technical & business services](https://busy.in/sac-code-9983/).

Geological consulting services help businesses understand how rocks, soil and underground formations will behave before they invest in mines, tunnels, dams, real estate or other infrastructure. In practical terms, clients use these services to reduce risk, avoid surprises at site and plan safer, more stable projects.

SAC 998341 is used when the main work relates to professional geological and geophysical consulting for infrastructure, mining and construction. It covers assignments where experts study site conditions, interpret investigations, advise on stability and suggest suitable designs or precautions.

Choosing SAC 998341 for such technical work keeps the nature of the service clear for both the consultant and the client and supports a consistent GST treatment for similar geological consulting projects.

## 998341 SAC Code GST rate

From a GST point of view, geological consulting services are treated as supply of services. The taxable value usually includes professional fees for field visits, data interpretation, report writing, model reviews and any related support that is billed as part of the same geological assignment.

After the September 2025 GST revision, most consulting, surveying and project support services without any special exemption remain under the standard 18% slab. Geological and geophysical consulting for business projects normally falls in this bucket. Registered business clients can generally claim input tax credit when these services are used for making taxable supplies or supporting business decisions, subject to normal ITC rules.

**The table below shows the latest standard GST rate for SAC code 998341**

| SAC code | Description | New GST rate (from 22 Sep 2025) | Old GST rate (till 21 Sep 2025) | Notes |
| --- | --- | --- | --- | --- |
| 998341 | Geological and geophysical consulting services | 18% with ITC | 18% with ITC | Technical consulting for geology and geophysics. Rate tables list 18% as default, with concessional 5 / 12 / Nil only where specially certified for FIFA U-17 event services. Typical commercial consulting stays at 18%. |

In practice, firms that provide geological consulting services should charge 18% GST on the taxable value, mention SAC 998341 on tax invoices and keep the same code in their GST records so that revenues from geology work are easy to identify and review later.

## Practical classification guidance

For this 9983 family, geological consulting services normally sit under SAC 998341, while other codes in the group should be used when the project is clearly subsurface surveying, mineral exploration, surface mapping, weather analysis or another defined service.

## Conclusion

SAC 998341 is meant for geological consulting services where experts assess ground and rock conditions for mines, infrastructure and construction sites. These services are generally taxed at 18% under GST, with ITC usually available to eligible business clients when the advice supports their taxable activities. Using SAC 998341 consistently with the correct GST rate in % helps keep service mapping and tax positions neat across geological projects.

These services help decide if land is suitable for mining, construction, tunnels, dams and other major infrastructure projects.

### Does SAC 998341 cover geological and geophysical surveys and investigation services?

Yes. Geological mapping, core drilling supervision, seismic and geophysical surveys, ground investigation, soil and rock testing advice and related reports are normally covered under SAC 998341. These services give technical data about the earth’s structure so that engineers, miners and planners can design safe and cost effective projects.

### What GST rate applies to geological consulting under SAC 998341?
