Open the Eight-year fund tax reserve calculatorWhat to prepare
- Have the figures for lot’s original acquisition cost (€), lot’s current value (€) and remaining months to eight-year event ready, from a dated document, with the period (annual, monthly or per transaction) that each input expects.
- Note the date of the transaction, since this model has no year selector and fixed rates may have changed.
- Compare your circumstances with the cited Official rules and guidance and Eight-year chargeable events before relying on the headline result.

How to interpret the result
Rates/conditions reviewed against the linked official sources on 5 October 2026. Distinguish a tax saving, a tax bill, cash received and money remaining: they are not interchangeable. An estimate does not establish eligibility, filing compliance or when a refund will be paid.
Change one input of eight-year fund tax reserve at a time and record the result; keep a record of the year, date and assumptions so a change in the result can be explained.
Common mistakes to avoid
- Do not mix tax years or apply a newly announced measure to an earlier transaction.
- Avoid counting an allowance, credit, contribution or loss twice.
- Check exclusions and personal circumstances before relying on the headline result.
