No London listing is held for this ISIN, so the fund is shown by its ISIN. That is the normal case here: the listing table covers 1,084 of the 2,755 share classes in this data. Check the ISIN against your contract note.

ERI is income you never received, and it lifts your cost base

A reporting fund can keep income instead of paying it out. You are taxed on the retained amount anyway: it is treated as arising to you on the fund distribution date, six months after the reporting period end (SI 2009/3001 reg 94(4)), and it goes on that year's return with no cash to show for it.

The same amount then increases the cost of your holding for Capital Gains Tax. That is what stops the money being taxed twice. Report the income and forget the uplift and you pay CGT on income you have already paid income tax on. Neither half appears on a broker's consolidated tax certificate, which is why it gets missed.

Every reporting period we hold for IE00BKPSFC54

You must have held units on the period end to be liable for that period. The income arises on the fund distribution date, and that date decides the tax year.

Sterling figures are shown to six decimal places; the calculator uses the unrounded value. The rate applied is HMRC's monthly rate for the month the income arises, which is the month the TaxBull calculator uses for the same figure. It is always an HMRC monthly rate, never a broker's rate and never a market feed (CG78310).

What 1,000 units would mean

If you held 1,000 units of IE00BKPSFC54 on 31 October 2024, the reporting period end, then:

Workings: 1,000 × USD 0.2118 = USD 211.80, ÷ 1.2978 (HMRC's April 2025 rate for USD) = £163.20. The excess is per unit, so 100 units instead of 1,000 divides every figure by ten.

What catches people out

Selling before the period end does not always get you out of it

Regulation 94(3A) of SI 2009/3001: if you sold units on or before the reporting period end and bought them back within 30 days, you are deemed to have held them at the period end anyway, so the income is charged. The uplift on those units goes onto the repurchase, not into the Section 104 pool, because the repurchase is what the earlier disposal is matched against under the 30-day rule. Sell and stay out for 31 days and the period is genuinely not yours.

Dividend or interest is not in this data, and it changes the rate you pay

A fund that fails the qualifying investments test (broadly, more than 60% in interest-bearing assets) pays its excess as interest rather than as a dividend (ITTOIA 2005 s378A). Interest is taxed at your income tax rate with the personal savings allowance, not at dividend rates with the dividend allowance. Nothing in this dataset says which a fund is. The manager's own report does, and a bond fund's excess taxed as a dividend is the wrong tax at the wrong rate. In the calculator you can classify a holding as an interest fund and the figures follow; unclassified, it is treated as a dividend and the report says that it assumed so.

The cost uplift also belongs to units you have already sold

The uplift attaches to the units you held at the period end. If you have since sold the whole holding, the uplift does not disappear. It belonged to the cost of what you sold, and leaving it out overstates the gain. The calculator applies it as a dated adjustment on the distribution date, so a disposal made before the period end never picks up a slice of it.

Where this figure came from

Manager: iShares (BlackRock ETFs). Periods held here: 31 October 2020 to 31 October 2024. Currency as reported: USD.

These are the manager's own published UK reporting-fund figures, taken from the documents it publishes. A period that is missing from this page is missing, not nil: if the manager published one we do not hold, the figure is still yours to report.

Check it at the manager: https://www.blackrock.com/uk/solutions/adviser-resources/reporting-fund-status. BlackRock's reporting-fund-status page, which covers the iShares range. iShares' own tax-information page returned 404 when checked on 2026-09-21.

Work out the tax →

Upload your broker CSV and the calculator applies excess reportable income for every fund it can identify: the income row in the right tax year, and the Section 104 uplift, alongside same-day, 30-day and pooling. A period it does not hold is named rather than treated as nil. The guide explains the matching rules.
