Understanding GST obligations as a small business owner can be confusing - different rates, registration thresholds, filing frequencies and claiming rules vary by country. The key is getting your bookkeeping right from the start. When every transaction is properly categorised with the correct GST treatment, filing becomes simple and you maximise your GST credit claims while staying compliant.
Check if you need to register for GST based on your country's turnover threshold
Register for GST through your tax authority's online portal
Set up your accounting software with correct GST codes and rates
Issue tax invoices that include your GST registration number
Categorise every transaction with the correct GST treatment
Keep all tax invoices and receipts for at least the required retention period
File your GST returns on time and pay any amount owing
Businesses in Singapore operating under the GST system must meet these compliance requirements set by IRAS:
Operating above the registration threshold without being registered
Not issuing proper tax invoices to customers
Claiming GST credits on personal or non-deductible expenses
Not understanding the difference between GST-free, input-taxed and taxable supplies
Mixing personal and business bank accounts, making GST tracking difficult
Waiting until the end of the period to categorise transactions
