However, january showed a a fall of 6,9 % compare to january 2007, at 96,4 billions THB. Slight accident ? Or a trend ?
The BOT gives the figures (but without details) until december (here). As for the Ministry of Finance, its website is a real shame : its database is available only a few days per month.
However, you’ll find there the details by department (Revenue, Customs, Excises) and by type of taxes (VAT for instance). The details are important, much more than the total collected.
