Financial assistance in the form of grants is subject to the normal taxation rules, as supplemented by ICTA88/S93 (see BIM40465). Under normal rules the tax treatment of grants will depend on whether they are capital or revenue.
Grants, which meet revenue expenditure, such as interest
payable, are normally trading receipts.
See also Smart v Lincolnshire Sugar Co. Ltd [1937] 20TC643
and Burman v Thorn Domestic Appliances (Electrical) Ltd [1981]
55TC493.
Grants, which meet capital expenditure, are normally not trading
receipts.
Grants that may be capital in nature include those paid to
acquire capital assets or to facilitate the cessation of a trade or
part of a trade.
See The Seaham Harbour Dock Co. v Crook [1931] 16TC333).
A capital grant reduces the qualifying capital expenditure
for capital allowance purposes, see CA14100.
You can find guidance on how grants are set against capital
expenditure for CG purposes at CG15288 (TCGA92/S50).
You can find guidance on how a capital grant may be treated
as being derived from the disposal of assets (for example,
goodwill) at CG12940 onwards (TCGA92/S22).
Some grants may not be for a specific purpose. These are termed
undifferentiated receipts. An undifferentiated receipt should be
regarded as on revenue account (see Poulter v Gayjon Processes Ltd
[1985] 58TC350 and Ryan v Crabtree Denims Ltd [1987] 60TC183).
For the treatment of undifferentiated grants from Highlands
& Islands Enterprise see
BIM40470.

guidance, should be referred to CT&VAT (Technical).
