Calculating your levies
Find out how we calculate your levies and what you need to use our calculators.
Estimate your levy
Estimate how much your business levies will be for the year, so that you know what to expect when your invoice arrives.
If you've received an invoice from us
When you file a tax return Inland Revenue passes your details on to us. We then invoice you for levies. This happens whether you're self-employed or have staff.
