Revenue “Cancellation of Income Tax Registrations” Notice



From 10th February 2023 the Revenue Commissioners are posting out letters to taxpayers who are currently registered for Income Tax but who have not submitted Income Tax Returns for years of assessment up to and including 2021.



The letters state:

“Based on a review of your Income Tax records, you have not filed any self-assessed Income Tax returns for years up to and including 2021.”


Taxpayers should start receiving such letters from 13th February onwards.


Please be aware that your Tax Agent won’t receive a copy of this notice.




What are you required to do?

In the event that the taxpayer is no longer deemed to be a “chargeable person” and, therefore, is no longer required to file an Income Tax Returns, he/she/they should cancel the Income Tax registration.


The term “chargeable person” applies to an individual who:

  1. Is self employed or
  2. Is a Director of an Irish company or
  3. Has other sources of income in addition to a PAYE salary.


An individual who is in receipt of PAYE income as well as non-PAYE income will not, however, be regarded as a “chargeable person” provided:

  1. the total gross income from non-PAYE sources is less than €30,000 and
  2. the net assessable income is less than €5,000 and
  3. the tax is collected by reducing his/her/their tax credits through the PAYE system.


A chargeable person is obliged to file an annual Income Tax Return through the self-assessment system.





How can you cancel your IT registration?

This can be done online via ROS or by completing a Form TRCN1 which is available on the Revenue website.





What happens if you are considered to be a “Chargeable Person”?

If the taxpayer is considered a “chargeable person” but has not filed Income Tax Returns up to 2021, the letter is deemed to be a Final Reminder to file all outstanding income tax returns.

If the taxpayer does not file the outstanding Income Tax Returns or cancel the registration within 21 days of the letter, Revenue will cease the income tax registration without further notice.

Once the Income Tax registration is ceased, if the taxpayer wishes to re-register for income tax he/she/they will be required to submit an online application via ROS.




Final Points


The Notice states:

“You should note that, where further information comes to Revenue’s attention that you were a chargeable person for any relevant tax year, Revenue reserves the right to reinstate your Income Tax registration.

The non-filing of a required tax return by chargeable persons can result in further contact from Revenue, including a follow-up compliance intervention. Non-filing of a return where required is also an offence for which a person can be prosecuted.”

Research & Development (R&D) Tax Credit – Ireland

globe on newspaper2



Ireland’s Research and Development tax credit system is a valuable tax based incentive, providing major benefits to both multinational companies and SMEs operating in Ireland.  The R&D tax credit was first introduced in the Finance Act 2004 and has been subject to various amendments in the subsequent Finance Acts.

The credit operates by providing up to 25% of R&D expenditure incurred by a company on qualifying R&D activities (both revenue and capital) in a tax credit or in cash (subject to certain conditions being met). This 25% tax credit can be claimed in addition to the normal 12½% revenue deduction available for the R&D expenditure.  Therefore, the total tax benefit to a limited company is 37½% being the 12½% standard corporation tax rate plus the 25% R&D Tax credit.



How can the Credit be used?

Companies are entitled to a credit of 25% of the incremental R&D expenditure incurred for periods commencing on or after 1st January 2015.

The credit can be used to:

  • Reduce the company’s corporation tax liability of the current period.  Where the credit exceeds the corporation tax liability for the current year, the excess can be carried forward indefinitely to offset against future corporation tax liabilities or
  • Reduce the corporation tax liability of the previous year i.e. the company can make a claim for the excess to be carried back or offset against the preceding period’s corporation tax liability or
  • If unused, the credit can be refunded by the tax authorities subject to certain restrictions.  The only restriction in obtaining a cash refund is that the R&D credit refund cannot exceed the PAYE/PRSI remitted by the company to Revenue in the last two years or the corporation tax liability for the prior ten years if higher.

The claim must be made within one year of the end of the accounting period in which the expenditure has been incurred.



It can alternatively be used as a key employee reward mechanism to remunerate R&D staff effectively, tax free subject to certain conditions.  The effective income tax rate for such key employees may be reduced to a minimum of 23%, provided certain conditions are met by the company and the individual.
