Corporation Tax Registration with Revenue


Most limited companies in Ireland are legally required to register for Corporation Tax (CT) with The Office of the Revenue Commissioners (Revenue) within 4 weeks from the date of first income. If no income has yet been received, then the period for registration is within 12 months from the incorporation date.

CT Registration is a necessary minimum and of highest priority when setting up as it entails attribution of a Tax Registration Number (TRN) for your company, while Registration for Employers Tax (PAYE), Relevant Contract Tax (RCT), Value Added Tax (VAT) is rather secondary and based on CT Registration.

How do I Register my Company for Corporation Tax in Ireland?

To register your company for tax, you must first obtain a CRO number issued by the Companies Registration Office (CRO).

According to Revenue, if you have a tax agent representing your company, then your application for tax registration must be submitted through Revenue Online Service (ROS) by your tax agent on your behalf.

If your company is not represented by a tax agent, you must submit a Form TR2 for Irish resident companies or Form TR2 (FT) for foreign companies your own.

Please note: The above options are mutually exclusive. Revenue warns that they will not process your paper application if you were supposed to submit an online one.

Anyway, under existing laws, all the companies are required to make payments and returns by electronic means using ROS.

In case you opt for Corporation Tax registration with Revenue Service for your company, Chern & Co team can become your tax agent and go through the whole procedure on your behalf.

After successfully submitting the form to the Revenue and its further processing be Revenue you will be given a Tax Registration Number.

What is a Revenue Online Service (ROS)?

This governmental online service allows, in particular:

·        to view your current position for various taxes and levies

What is a Tax Registration Number?

A Tax Registration Number (TRN) is issued by Revenue when you register for tax as a sole trader, trust, partnership, or company. You must use your TRN when trading and filing your tax returns.

After finally getting the TRN, you are free to conduct all the business operations and to open a company business bank account, which you may need.

How long does Corporation Tax Registration take?

The Revenue Commissioner usually takes a minimum of 5 working days to issue your tax number (TRN) depending primarily on your application and other factors beyond our or your control. Practice shows that this procedure may take either a couple of weeks or a couple of months.

Please note: Chern & Co team will prepare your application and do all the relevant work in a timely way, but we cannot guarantee further registration time by official authorities. Registration may be delayed depending on the current workload and staff availability of Revenue.
