iShares Excess Reportable Income for 2025 Now in the Calculator

product-updateseri

Our bundled Excess Reportable Income (ERI) data for iShares ETFs had stopped at April 2025. That is seventeen months behind. If you hold an iShares fund outside an ISA and ran a 2025/26 report before 3 October 2026, the report could not have applied the fund’s 2025 figure, because we did not have it. It does now. Re-run the report.

What was added

  • iShares: the 2025 reporting year of all seven umbrellas (periods ending May, June, July, October and November 2025), plus iShares plc to February 2026 and iShares VI to March 2026. 859 entries.
  • BlackRock Global Funds: the period ended 31 August 2025. 608 entries.
  • Invesco Markets II plc (FWRG and the bond ETFs): the period ended 31 December 2025. 177 entries.
  • Invesco Markets plc (the FTSE 100, FTSE 250, EURO STOXX 50 and MSCI trackers): a range we had never bundled. Every period from November 2018 to November 2025, 592 entries.

That is 2,236 new entries, taking the ERI reference data from 11,896 to 14,132. Vanguard, VanEck, Amundi and State Street were already current. Xtrackers has not yet published its December 2025 report, and State Street has not published March 2026; both will be added when they appear.

Which iShares ETFs now have 2025 Excess Reportable Income

Each iShares umbrella has its own year-end, so the new periods fall on different dates and the income lands in different tax years. The fund distribution date, when the income counts as received, is six months after the period end. For the funds UK investors ask about most:

  • CSPX (iShares Core S&P 500) and CNDX (iShares NASDAQ 100): period ended 31 July 2025, income dated 31 January 2026, tax year 2025/26.
  • SWDA / IWDA (iShares Core MSCI World): period ended 30 June 2025, income dated 31 December 2025, tax year 2025/26.
  • ERNS (iShares £ Ultrashort Bond): period ended 31 May 2025, income dated 30 November 2025, tax year 2025/26. The figure is nil.
  • IITU (iShares S&P 500 Information Technology Sector): period ended 30 November 2025, income dated 31 May 2026, tax year 2026/27.
  • EMIM / EIMI (iShares Core MSCI EM IMI) and ISF (iShares Core FTSE 100): period ended 28 February 2026, income dated 31 August 2026, tax year 2026/27.
  • FWRG (Invesco FTSE All-World): period ended 31 December 2025, income dated 30 June 2026, tax year 2026/27. SPXP (Invesco S&P 500): period ended 30 November 2025, income dated 31 May 2026, tax year 2026/27.

Any other fund: type the ISIN or ticker into the ERI reference data and it lists every period we hold. The ERI documentation explains how the figure reaches the report.

Why it was out of date

BlackRock used to list the iShares ETF reports on its UK reporting-fund page. It no longer does. The workbooks moved to the iShares document library, where the list is filled in by a script, and our monthly check still looked at the old page and found nothing new. A customer noticed first: his report named no figure for the iShares £ Ultrashort Bond ETF’s period ended 31 May 2025. The figure turned out to be nil, so his numbers did not move, but the gap was real for everything else iShares had published since.

What we checked before shipping it

Every new entry was read back from the provider’s own workbook or PDF a second time, by separate code, and compared on ISIN, reporting period, currency and figure. All 2,236 matched. We also re-read three reports we already held (iShares plc 2025, iShares VI 2025, Invesco Markets II 2024) and confirmed they reproduce the bundled figures to the last digit.

The Invesco reports taught us something. In the 2018 to 2020 editions the dividend paid is printed before the excess reportable income, so “take the first number after the currency” would have booked dividends as ERI. The check above caught it before anything was published. The excess is now read as the figure that sits beside the fund distribution date, six months after the period end, which holds in every year Invesco has published.

Two Invesco figures were left out rather than guessed. The RDX ETF for the period ended 30 November 2018 has no currency printed against it, and the STOXX Europe 600 Optimised Utilities ETF for 30 November 2019 is printed in US dollars while every other year prints euros. If you held either, the report will name the missing period and you can enter the figure yourself under Edit → Advanced → Custom ERI Entries.

What ERI does to your return

A reporting fund’s excess reportable income is taxed as your income for the year in which the fund distribution date falls, six months after the fund’s period end, even though no cash arrives. The same amount is added to the allowable cost of your holding, so it is not taxed again as a gain when you sell. A missing period therefore understates your income for one year and overstates your gain later. Our guide to reporting ERI covers the mechanics, and accumulating vs distributing ETFs explains why accumulating share classes are where most of it sits.
