Corporate and personal tax consulting services under these SAC codes are treated as professional tax advisory services under GST. The taxable value normally covers consultation fees, return filing charges and retainer amounts, excluding any income tax, penalty or other direct tax payments that are deposited on behalf of clients and recovered at actuals.
Post the September 2025 rationalisation, most taxable tax consulting and return filing services generally fall in the 18% GST slab with input tax credit for eligible registered clients. Certain services to specific categories of taxpayers may be governed by special conditions or reverse charge as per updated GST notifications, so these rules should be checked before raising invoices.
The table below explains the prevailing GST treatment for SAC code 998231, indicating the usual 18% slab for taxable tax consulting services and any notified exceptions.
