The ESRI did more analysis of the impact of this:
5.5 CAPITAL ACQUISITIONS TAX (CAT) BUSINESS AND AGRICULTURAL RELIEF
In addition to annual and lifetime CAT-free allowances, individuals who inherit or receive a gift of certain business or agricultural assets can avail of Business or Agricultural CAT Relief.32 This reduces the taxable value of eligible assets by 90 per cent, which – combined with the lifetime allowance of €335,000 – means that a business or farm worth up to €3.35 million can be gifted or bequeathed by a parent to a child without giving rise to any CAT liability. Similarly, a business or farm worth up to €10.05 million can be gifted or bequeathed entirely CAT-free by a parent of three children to those children if given in equal shares.
The stated rationale for these reliefs is – as with CGT retirement relief – to support the growth of and succession within small family farms and businesses (Department of Finance, 2018, 2014). However, Revenue statistics show that in 2019 there were 648 claims for Business Relief at a cost of €200.4 million and 1,413 claims for Agricultural Relief at a cost of €158.6 million: an average cost per claim of €309,259 and €112,243 respectively. This suggests that the primary beneficiaries – of Business Relief in particular – are not those inheriting or being gifted small family farms or businesses, but far more substantial ones. Furthermore, given that there is strong evidence that inherited family-owned and -run firms are, on average, very poorly managed (Bloom and van Reenan, 2010), the goal of supporting the growth of and succession within family businesses should be weighed against the wider economic costs of discouraging the disposal of business assets to third parties.
Citing excess generosity to those inheriting larger farms and businesses, the Commission on Taxation (2009) recommended reducing the rate of both reliefs to no more than 75 per cent, with a cap of €3 million on eligible assets. While no costing is available for what capping the relief would raise, Revenue (2020) estimate that almost €60 million would be raised by reducing both reliefs to 70 per cent and €135 million by reducing both to 50 per cent.
