The government expects to earn double the cost of its subsidies for stimulus measures, says permanent secretary for finance Somchai Sujjapongse.
The measures will boost people's spending and economic growth and the government's tax revenue will double, he said, referring to a Finance Ministry study.
The government's burden from the stimulus will not have any adverse impact on fiscal status because most measures are subsidies of interest rates for loans, Mr Somchai said.
The government's quick-start investment scheme includes corporate tax deductions of up to two times depreciation costs for the 2015 and 2016 tax years.
Mr Somchai said the government must shoulder interest costs of 1.2 billion baht a year for interest-free loans worth almost 60 billion baht to Village Funds for the first two years, 4.2 billion from incentives that let small and medium-sized enterprises (SMEs) gain better access to loans, and 16 billion for a six-month cut in housing transfer and mortgage fees to 0.01% each plus a tax deduction of 20% of home value from first-time homebuyers' taxable income over five years for homes priced 3 million baht or less.
Measures to lure SME operators to have a single financial account and enter the formal tax system will boost the government's coffers as these operators have never paid corporate income tax, he said.
Mr Somchai said the Finance Ministry was concerned that VAT revenue could miss the target because of tumbling oil prices.
The extra revenue contributed from the recent licence auctions for fourth-generation wireless broadband services will offset some missing revenue, he said.
The government's revenue target is 2.33 trillion baht for this fiscal year.
