As and from the 23rd November 2020 all adult applicants for a certificate of naturalisation are required to have an up to date tax clearance certificate.
For applicants resident in the State a Tax Clearance Certificate (TCC) is a written confirmation from Revenue that a person’s tax affairs are in order at the date of issue of the certificate and applications can be made online to the Revenue electronic Tax Clearance (eTC) system. The necessary information to use this service is available on the Revenue website here. You should provide the Tax Clearance Access Number (TCAN) issued to you or print and provide a copy of the certificate.
For applicants who reside outside the State, a TCC is required or where this service may not be available by the relevant Revenue authorities then confirmation of tax compliance in the relevant jurisdiction from the Revenue authority is required.
It is advisable not to apply for a certificate of naturalisation without a tax clearance certificate or a Revenue letter of tax compliance.
