Frequently Asked Questions
When do I need to register for GST in Singapore?
You must register for GST if your taxable turnover exceeds S$1 million in a 12-month period, or if you expect it to exceed S$1 million in the next 12 months. Voluntary registration is also available if your turnover is below this threshold. Contact IRAS or a tax adviser for guidance specific to your situation.
How do I apply the correct GST rate on my Singapore invoice?
Enter your applicable GST rate in the invoice builder — Bilto calculates the GST amount and totals automatically. GST rates in Singapore may change over time. Always verify the current rate applicable to your goods or services with IRAS or a tax adviser before issuing invoices.
Do I need to issue a tax invoice for every sale?
GST-registered businesses must issue a tax invoice within 30 days of the time of supply for taxable supplies made to GST-registered customers. For supplies to non-GST-registered customers, a simplified tax invoice or receipt may be issued instead.
Can I issue invoices in foreign currency?
Yes, but the GST amount must be expressed in Singapore Dollars (SGD). If you invoice in a foreign currency, you must convert the GST amount to SGD using an acceptable exchange rate (e.g., the rate published by the Monetary Authority of Singapore).
What is the difference between a tax invoice and a simplified tax invoice?
A standard tax invoice is required for B2B supplies above S$1,000 to GST-registered buyers. A simplified tax invoice can be issued for supplies not exceeding S$1,000, omitting some fields like the customer's details. Bilto generates standard tax invoices suitable for all amounts.
