TransferWise does not levy any tax on its transfer fee. This means you will not be charged Value Added Tax (VAT), Goods and Services Tax (GST) or any other indirect tax.
TransferWise will pay out the agreed amount to the recipient and will not withhold any taxes on money transferred. Depending on the nature of a transfer the payee and/or the recipient may have their own obligation to declare and pay tax. TransferWise cannot advise whether tax applies to your transfer and recommends you ask a financial advisor and/or the relevant tax authority.
