There are a number of tax reliefs that are available for companies in 75% relationships. These include group relief for corporation tax and chargeable gains. SDLT has similar provisions.
A transaction is exempt from SDLT under FA 2003, Sch. 7, Pt. 1 if the vendor and purchaser are companies that are members of the same group as at the effective date of the transaction.
For this purpose, ‘company’ means a body corporate, so unincorporated associations are not covered. Companies are members of the same group if one is the 75% subsidiary of the other or both are 75% subsidiaries of a third company.
