Frequently Asked Questions
What is the difference between adding and removing tax?
Adding tax calculates the final price when the entered price is before tax (net). Removing tax extracts the tax component from a price that already includes tax (gross). For example, removing 20% VAT from £120 gives £100 net and £20 tax.
How is VAT calculated?
To add VAT: Final price = Net price × (1 + rate / 100). To remove VAT: Net price = Gross price / (1 + rate / 100). Tax amount = Gross price − Net price.
What are common VAT and sales tax rates?
VAT rates vary by country: UK 20%, EU average ~21%, Australia 10% (GST). US sales tax varies by state from 0% to ~10.25%. Always check your local rate as they can change.
