GlaxoSmithKline Pharmaceuticals Limited received a tax refund of ₹52.00 crore for Assessment Year 1984-85 on August 6, 2026, following a final order from the Commissioner of Income Tax (Appeals). The resolution of this decades-old assessment resulted in additional interest income of ₹42.09 crore, which the company has credited to its profit and loss account. This inflow represents a significant non-operational boost to the company’s financials, closing a prolonged dispute with tax authorities.
The disclosure was made under Regulation 30 of the Securities and Exchange Board of India (Listing Obligations and Disclosure Requirements) Regulations, 2015. GlaxoSmithKline informed the Bombay Stock Exchange and the National Stock Exchange of India Limited regarding the receipt of the Order Giving Effect (OGE) to the CIT-Appeal. The OGE was issued on January 27, 2026, but the actual funds were credited to the company’s bank account on August 6, 2026.
Key Details of the Refund
The tax authority involved was the ACIT Cir 7(1)(1), which had previously determined a demand liability of ₹23.21 crores. However, the final appellate order reversed this position, leading to the substantial refund. There were no violations or contraventions alleged by the authority in the final communication.

| Refund Amount | ₹52.00 Cr |

Financial Impact
The primary material impact of this event is the recognition of ₹42.09 crore as interest income. This amount is distinct from the principal refund of ₹52.00 crore. The interest accrued over the extended period between the original assessment year and the final settlement. By crediting this to the profit and loss account, GlaxoSmithKline will see a direct positive impact on its net profit for the period in which the refund was received.
What the Numbers Show
The magnitude of the interest income relative to the principal refund highlights the duration of the dispute. With interest totaling ₹42.09 crore on a principal of ₹52.00 crore, the cost of capital for the tax authority over the intervening years was significant. For investors, this is a one-time, non-recurring gain that improves bottom-line metrics but does not reflect operational performance. The closure of the AY 1984-85 assessment also eliminates any future contingent liability or uncertainty associated with this specific fiscal year.
