Corporation tax rates

Standard Rate

The standard rate of corporation tax is 12.5% .

Start-up companies

A start-up trading company can get a three-year exemption which reduces its corporation tax charge (up to €40,000 per annum) to nil.

There is marginal relief if the charge is between €40,000 and €60,000. In theory, this means a start-up company can earn annual net profits of €320,000 (€40,000 divided by 12.5%) and pay no tax.

However, the relief is linked to the amount of the employer’s PRSI paid by the claimant company, subject to a maximum of €5,000 per employee, and an overall limit of €40,000. The relief does not apply to trades carried on by associated companies.

Warning: you need to have employees in order to claim this relief.
