Tax rules

Deemed disposal, explained

Every eight years, Irish fund and ETF investors are taxed on a gain they never received. It is the single biggest reason Irish households hold over €160bn in deposits instead of markets — and it is the rule the new Personal Investment Account is designed to sidestep.

Updated September 2026

The rule in one paragraph

If you hold an Irish or EU-domiciled fund — which includes almost every ETF sold to Irish retail investors — Revenue treats you as having sold it on the eighth anniversary of purchase. You pay 41% investment undertakings tax on the paper increase in value, in cash, from your own pocket. You still own the fund. No money changed hands. The clock then resets for another eight years, and any tax already paid is credited when you finally sell.

What it actually costs

The damage is not the 41% itself — it is the compounding you lose by paying tax decades early. Take €10,000 invested at 6% a year, with tax paid from outside the account at each eight-year mark:

Year	Value before tax	Deemed disposal charge	Running tax paid
8	€15,938	€2,435	€2,435
16	€25,404	€3,880	€6,315
24	€40,489	€6,184	€12,499
32	€64,534	€9,858	€22,357

Illustrative: €10,000 lump sum, 6% annual growth, 41% charged on the gain in each eight-year period, tax funded from outside the fund. Rounded. Your outcome depends on actual returns and timing.

Sell in year 32 and you would have handed over roughly €22,400 in instalments, most of it taken long before you saw a cent. Under a flat-rate account with no deemed disposal, the same portfolio keeps that money invested and working.

Why it is worse than CGT

	Fund / ETF (IUT)	Direct shares (CGT)
Rate	41%	33%
Annual exemption	None	€1,270
Offset losses against gains	No	Yes
Tax before you sell	Yes — every 8 years	No
Self-assessment required	Yes, Form 11 / IT38 style filing	Yes

Investment undertakings tax (IUT) versus capital gains tax as they stand in 2026.

The asymmetry pushes ordinary savers towards single stocks, which are riskier, or towards deposit accounts, which lose to inflation. That distortion is exactly what the Department of Finance roadmap set out to fix.

What the Personal Investment Account changes

The roadmap, Taxation of Retail Investment: A New Path Forward for Ireland, published on 31 August 2026, confirms the design of the new account:

Tax is applied annually at a flat rate, only on account value above a tax-free threshold.
The charge is calculated on average valuations and is final — no further tax on sale.
Deemed disposal will not apply inside the account.
No minimum holding period, and tax-neutral transfers between providers are intended.
Qualifying assets: listed shares and bonds, retail funds including ETFs, and insurance-based investment products. Derivatives and crypto are excluded.

Still undecided

The annual contribution limit, the size of the tax-free threshold and the flat rate itself are all deferred to Budget 2027. Reform of deemed disposal for holdings outside the account is pushed to Budget 2028 at the earliest, and the Government has not promised to abolish it.

What to do with an existing ETF holding

Nothing in the roadmap allows you to move an existing fund into the new account tax-free, and no transitional relief has been announced. If you hold funds today, three practical points:

Your eight-year clock keeps running. Diarise each purchase date — the obligation to calculate and file is yours, not your broker's.
Tax already paid on a deemed disposal is credited against the eventual exit tax, so you are not taxed twice on the same gain.
Wait for Budget 2027 before restructuring. Selling early to "get ready" crystallises 41% immediately, which is usually worse than any plausible transitional rule.

Frequently asked

What is deemed disposal in Ireland?

Deemed disposal is a rule that treats an Irish or EU-domiciled fund or ETF as if you sold it every eight years. Tax is charged on the paper gain at 41% even though you still hold the investment and received no cash.

Is deemed disposal being abolished?

Not yet. The Department of Finance roadmap published in August 2026 confirms deemed disposal will not apply inside the new Personal Investment Account from 2027, and says wider reform of deemed disposal for existing fund holdings will be examined from Budget 2028 onwards. The Government has not committed to removing it entirely.

What rate applies on deemed disposal?

Investment undertakings tax is charged at 41% on the increase in value over the eight-year period. It is not capital gains tax, so your annual €1,270 CGT exemption does not apply and losses on other investments cannot be offset.

What happens if I sell before eight years?

You pay 41% exit tax on the gain at the point of sale. The eight-year clock only matters if you are still holding. If a deemed disposal has already been paid, that tax is credited against the final bill when you eventually sell.

Does deemed disposal apply to individual shares?

No. Directly held shares are taxed under capital gains tax at 33% when sold, with the €1,270 annual exemption. Deemed disposal applies to funds, including most ETFs and life-assurance investment products.
