What Does DIRT Stand For In Business?

In the context of Irish business and finance, “DIRT” stands for Deposit Interest Retention Tax. It’s a form of tax deducted at source by Irish financial institutions on interest earned by individuals on savings and deposit accounts. Let’s delve deeper into the world of DIRT for those unfamiliar with its intricacies.

Understanding DIRT in the Irish Business Landscape:

What is DIRT?

DIRT is a tax that applies to the interest you earn on savings and deposits in Ireland. Essentially, if you have money saved in a bank account and that money earns interest, a certain percentage of that interest will be automatically taken as tax before it gets to you. This is a way the Irish government collects tax on savings income.

Who pays DIRT?

In general, all Irish resident individuals who earn interest on savings and deposits will have DIRT deducted from their interest. However, there are certain exemptions and reliefs available, especially for elderly or incapacitated individuals.

How is DIRT calculated?

The rate of DIRT has fluctuated over the years based on government budgets and economic conditions. It’s essential to check the current rate when calculating your DIRT obligations or expecting interest payments. Financial institutions will automatically deduct this tax before paying interest to the account holder.

Exemptions and Refunds

Certain individuals may be exempt from paying DIRT or might be eligible for a refund. This includes:

Elderly individuals: Those aged 65 and over, with a total income below a certain threshold, can claim an exemption or a refund.

Incapacitated individuals: If you’re permanently incapacitated, you may also qualify for DIRT exemptions or refunds.

It’s advisable to consult with a tax professional or the Revenue Commissioners to understand if you qualify for any exemptions or how to claim a refund.


DIRT, or Deposit Interest Retention Tax, plays a significant role in the Irish tax landscape, affecting many individuals with savings and deposits.

Understanding DIRT, its implications, and potential exemptions can help individuals and businesses manage their finances more effectively in Ireland.
