Common tax-aware options in Ireland include an occupational pension, PRSA or AVC (additional voluntary contribution), where contributions may qualify for income-tax relief subject to age, earnings and Revenue rules, but access is generally restricted until retirement. Ordinary deposit accounts are straightforward, but interest may be subject to DIRT, while investments can involve income or capital gains tax depending on the product and how it is held. Tax treatment, charges, risk, access and time horizon all matter, so the most suitable option depends on your circumstances rather than tax efficiency alone. Check current guidance on revenue.ie and consider regulated advice before making a decision.
