AVCs (Additional Voluntary Contributions) are extra payments you make into your occupational pension scheme to boost your retirement fund. You can claim tax relief on AVCs at your highest tax rate (20% or 40%), which reduces the amount of tax you pay.  You won’t automatically get tax relief through payroll — you need to claim it through Revenue myAccount or your annual tax return. The amount you can claim each year depends on your age.
