Tea development account deduction for deposits in a scheme account reduces taxable business profits when funds are properly utilised. A Tea development account provision allows a deduction for tea growers/manufacturers who deposit amounts in a designated special account with the National Bank under a Tea Board-approved scheme, limited to deposits or twenty per cent of business profits (whichever is less); excess deposits may be carried forward. Utilisation of released sums for acquiring assets reduces the asset's taxable cost and utilisation for expenditure reduces deductible expenditure; amounts released but not utilised within the year are treated as business income and taxed accordingly.
