The finance bill is out. Plenty of detail on the SIA (or Individual Investment Account (IIA) as the bill formally names them) in Section 26.
The bill allows for accounts from 1 January 2027, so the Minister can commence them any time thereafter with an order (I think they're targeting July). Nothing in the bill about whether 2027 will be pro rated or treated as full year - the bill just gives a limit of €12,000 per year of assessment. I read that as you could put in €12k in 2027 even if the account opens July.
The detail that surprised me most is that closing an account early in the year can still trigger the full annual charge (maybe - there's a good discussion on it below in the thread).
A few other details that caught my eye, some of which were guessed at already: withdrawals don’t restore your contribution allowance, excess contributions attract 1% tax per month, cash cannot earn interest, and emigrants face restrictions on switching providers.
1. The tax uses a daily average, not the year-end balance
The account value includes both investments and cash. The calculation adds up the daily closing values and divides by the number of days the account was open.
An account with an average value of €80,000 would therefore incur €300 tax, even if its closing value on 31 December were €100,000.
This may make the timing of contributions and withdrawals relevant to the charge.
References: 747H, 747Q.
2. Withdrawals do not restore your contribution allowance
The €12,000 limit applies to gross contributions, without deducting withdrawals. Taking money out does not create fresh room to contribute.
Closing the account also prevents you from opening another during the same calendar year. A formal provider transfer is treated separately.
Reference: 747L.
3. Excess contributions attract 1% tax per month & a penalty for the provider
An outstanding contribution above the annual limit attracts 1% per month on the excess, even where the account is below €50,000.
An unresolved €1,000 excess therefore generates €10 tax for each chargeable month. It carries into subsequent years until corrected; a new calendar year does not automatically clear it. Withdrawals are applied to reduce outstanding excess amounts. Timing helps here. The charge is based on the excess outstanding at the end of each month, and a withdrawal counts from the end of the month in which it is made. So an excess withdrawn in the same month it arises should attract no tax.
There is also a separate €3,000 penalty on the provider if it accepts an excess contribution without reasonable excuse.
Reference: 747R.
4. Cash in the account cannot earn interest
The Bill expressly prohibits interest being paid, credited or allowed to accrue on cash balances. Cash nevertheless counts towards the account value used for the annual tax.
References: 747H, 747L(2)(f).
5. The eligible investment and provider lists are fairly broad
Eligible investments include:
Reference: 747H.
6. You can switch providers, but an investment transfer is not guaranteed
A formal transfer preserves the account’s contribution and tax history and does not itself use up the annual contribution allowance.
However, transferring the investments themselves requires both providers to agree. Otherwise, the investments are sold and the cash proceeds transferred for reinvestment. Contributions, withdrawals and other transactions are restricted during the statutory transfer process.
References: 747W, 747X.
7. Emigration restricts both contributions and provider switching
You can keep your account when non-resident. During the defined period of non-residence, you cannot contribute or request a transfer to another provider, apart from the specified exception where the existing provider is ceasing to operate.
The restriction starts when you leave if you intend to be non-resident for that tax year, or on 1 January of the following year if you remain Irish tax-resident in your departure year but intend to be non-resident the following year.
The start and end dates turn on your intention when leaving and returning. There is a 30-day grace window. Contributions accepted within 30 days of your provider being notified (or otherwise finding out) still count. After that, contributions are treated as never made and refunded. If they have already been invested, you get the market value less dealing costs.
(For comparison, a UK ISA allows you to switch providers while non-resident.)
Reference: 747M.
8. The wrapper can continue temporarily after death
Contributions stop on death, but the account’s tax treatment can continue during the specified estate-administration periods.
Broadly, a transition period begins at the earlier of the grant of probate/administration or three years after death. It ends at the earlier of completion of the estate administration or one year after that transition period begins. There are separate provisions for closure without a grant.
The legislation provides for liquidation during the transition period and, if investments remain when it expires, a deemed disposal and reacquisition at market value as the wrapper ends. The closure rule above also applies here. Once the personal representatives sell the last holding, the account is treated as closed, so an estate that liquidates early in a year pays the full rate on that year’s average to date
Reference: 747Y.
9. Closing early still triggers the full annual rate (maybe!)
My read, but could be wrong: For an account closing during a year, the Bill substitutes the closure date for 31 December. The average value is calculated using only the days the account was open, and the resulting amount above €50,000 is multiplied by 1%.
Neither the €50,000 threshold nor the 1% rate is reduced for a short year. An established account with an average value of €100,000 during the period before closure would therefore incur €500 tax, even if it closed early in January.
The trap is the closure itself, not the withdrawal. If the same holder withdrew everything on 2 January but kept the account open with a nominal balance until 31 December, the average would be roughly €275 and there would be no tax. Anyone planning to empty an account may be better off leaving it open, subject to their provider’s terms. That also avoids the bar on opening another account that year.
That may be intended, but it seems a significant detail for anyone planning a withdrawal and closure.
Reference: 747Q(2)–(7).
10. Opening late, including July 2027, still seems to get the full €12,000
The Minister said accounts will open from 1 July 2027. The Bill itself only says providers can offer accounts on or after 1 January 2027, and leaves the actual start date to a ministerial commencement order.
Nothing in the Bill reduces the contribution limit for a part-year. The limit is simply €12,000 for a year of assessment, and contributions in a year must not exceed it. So on my reading, the full €12,000 can go in between July and December 2027.
This is for any year, I think. Anyone opening an account late in any year would seem to get the full year’s allowance. The drafting deals with part-years expressly when an account closes (see point 1), but not when one opens.

Eligible investments include:
- Shares and bonds admitted to trading on qualifying EEA markets or equivalent overseas markets.
- UCITS funds, including qualifying ETFs.
- Insurance-based investment products.
- Certain personal-portfolio and structured products are excluded, along with assets acquired through the employee-share provisions specified in the Bill.
- Eligible providers include specified banks, investment firms, insurers and UCITS management companies, with routes for qualifying EEA providers.
