Compulsory and voluntary GST registration in Singapore, plus the operational impact of charging tax to customers.

Goods and Services Tax is Singapore's broad based consumption tax. You must register once your taxable turnover crosses one million dollars over twelve months on a retrospective or prospective basis.

Voluntary registration

Some businesses register voluntarily to reclaim input tax on large capital expenditures or to appear more established to enterprise customers. Voluntary registration locks you in for at least two years, so weigh the administrative cost carefully.
