Tax Clearance Certs 

A Tax Clearance Certificate is confirmation from Revenue that a person's/entity's tax affairs are in order at the date of issue of the certificate. A condition of obtaining a public sector contract of a value of €10,000 or more, (inclusive of VAT), within any 12 months period, is that the contractor is required to produce a TCC or demonstrate a satisfactory level of tax compliance.  

The tax clearance requirement applies even where the provision of goods or services is not the subject of a formal written contract. 

Tax Clearance Certificate – Non Residents 

Non–residents who are not registered for Irish Tax cannot apply on-line for a TCC. The TCI is available on the Revenue website or by e-mailing nonrestaxclearance@revenue.ie. 


Relevant Contract Tax (RCT) 


Professional Services Withholding Tax (PSWT) 

A withholding tax, at the rate of 20 per cent, is deductible at source from payments for "professional services" made to individuals and companies by "accountable persons" (Government Departments, local authorities, health boards, State bodies, etc.). The tax is charged on payments net of value-added tax. 

Any person (including a company) receiving a payment from an accountable person in respect of professional services is liable for the tax. A wide range of professional services is included. Non-residents come within the ambit of the scheme but they are entitled to a full refund if the income is not chargeable to Irish tax.
