I wouldn't
The small gift exemption lets each parent give €3,000 per child per year free of Capital Acquisitions Tax.
So ye can gift €6,000 to each child annually, (which comes to €18,000 total across three children per year) and it won't affect their lifetime limits
Thats fine
The problem is CGT
The gifting a share of a property to someone is treated as a disposal at full market value, (even if no money changes hands.)
So if the property has gone up in value since ye bought it, you would owe 33% CGT on the gain of the portion you gift, every single year you do it.
( Revenue will not accept a discounted valuation either)
They substitute the open market value regardless.
There is no CGT on death.
When you die, you are not treated as having sold or transferred your assets & your children inherit the property at its market value on the date of death, and no CGT is owed from your estate on whatever gain built up during your lifetime.
By gifting incrementally you are triggering a tax liability that would simply not exist if you held the property and left it in your will.
Also, every transfer of a share in a property needs to be legally registered, which means solicitor fees each time, for each child.
Remember Stamp duty applies to each transfer too, at 1% of the value of the share being transferred.
It is also worth checking whether your children would face any CAT at all on inheritance.
The Group A lifetime threshold for parent-to-child transfers is currently €400k per child.
If the total value your estate passes to each child stays under that figure, they could inherit tax-free anyway,( with no annual gifting strategy needed)
Surely holding the property and passing it through your estate is almost certainly the better outcome for your family.
