GST is a simple formula
You work out GST by comparing the amount you paid on purchases to the amount you collected on sales.
If you get a positive number, you need to pay that amount to IRAS. If it’s a negative number, you’ll get a refund for that amount.
How to work out GST in four steps
1. Make a note of the GST paid on your business purchases
2. Make a note of the GST collected on sales
3. Add both types of GST
4. Run the GST formula
Avoid nasty surprises with smart bookkeeping
Like any business, you’ll be aiming to sell more than you buy. If you succeed in doing that, you’re most likely to end up with GST to pay. Run the four-step GST equation regularly so you can see how big your GST payment is shaping up to be.

You can use online accounting software like Xero to stay on top of GST. It automatically records GST collected and paid, and does the maths for you.
