Introduction

Group companies often share common office expenses — rent, utilities, and administrative costs. The question arises: How are shared expenses treated under GST?

The answer depends on whether the arrangement involves a cross-charge or an ISD distribution. This guide explains the legal framework and the practical implications.

Legal Framework: Cross-Charge and ISD

Cross-Charge

Where one group entity provides services to another, the cost allocation is a supply of services under GST, attracting 18% GST.

ISD Mechanism

Where common input services are received at the head office and need to be distributed to different GSTINs, the entity can register as an Input Service Distributor (ISD) and distribute the ITC through FORM GSTR-6.

ISD Registration Mandatory

Effective April 1, 2025, businesses with multiple GST registrations under a single PAN must obtain a separate ISD registration to distribute ITC for common services.

GST Treatment

Cross-Charge

The allocating entity charges GST on the allocated amount and reports it in GSTR-1. The receiving entity claims ITC.

ISD Distribution

The ISD distributes ITC to the recipient GSTINs without charging GST. The distribution is reported in GSTR-6.

Documentation Required

  • Cost Allocation Agreement: Documentation of the allocation terms.
  • Tax Invoice: For cross-charge transactions.
  • ISD Invoice: For ISD distributions.

Best Practices

  • Determine the Correct Mechanism: Assess whether cross-charge or ISD is applicable.
  • Register as ISD: Register as ISD where common services are received centrally.
  • Maintain Records: Document all shared expense arrangements.
  • Seek Professional Assistance: For complex group structures.

Conclusion

Common office expenses shared between group entities are treated as cross-charge supplies or ISD distributions. ISD registration is mandatory from April 1, 2025. Proper documentation is essential.
