As a Truster Pro Light user, your business name will be automatically registered in the Pre-tax Register and the VAT Register. We will also check that your existing business ID registrations are in order.

What is the Prepayment Register?

The Prepayment of Taxes Register is a register maintained by the Tax Administration, which allows businesses and traders to invoice their customers without withholding tax. This means that your customers do not have to withhold tax on payments if your Y-identification number is in the register.

What about the VAT register?

The VAT register, or register of VAT payers, is also maintained by the Tax Administration and includes companies and traders who are obliged to pay and account for VAT on the goods and services they sell. Truster handles the VAT returns and payments on your behalf.
