The tax date generally follows the fund’s defined distribution date, not simply the day cash appears in your bank. Equalisation is a separate capital component, so use the fund’s tax voucher to split income from returned capital and apply the correct tax treatment.

Keep the fund tax voucher and use the stated distribution date and equalisation amount when preparing your tax records.

HMRC investment-funds distribution guidance

The fund's distribution date is the starting point

For a UK authorised investment fund, HMRC says the distribution date is the date specified in the fund's constitutional documents or, if none is specified, the last day of the distribution period. Under FCA rules, a specified distribution date must be within four months of the end of the distribution period.

For offshore reporting funds, HMRC also taxes qualifying distributions and reported amounts by reference to the year in which the distribution is made. That is why a fund's tax voucher and distribution report are more reliable than the date you personally happened to notice the payment in your bank account.

Equalisation is not simply extra income

Equalisation is designed to prevent a new investor from getting too much of a distribution for income that built up before they bought the units. HMRC explains that a Group II investor can receive a distribution made up of income plus returned equalisation.

The returned equalisation element is a capital receipt, not income. For CGT purposes, HMRC says it should be deducted from the cost of the units. That means equalisation can affect the tax calculation twice: it changes the income portion of the distribution and later changes the acquisition cost used in a capital-gains calculation.

Why Group I and Group II units matter

Group I units are held throughout the distribution period. Group II units are bought part-way through it. A Group II investor receives a distribution that includes only the income accrued while they held the units plus the equalisation amount that effectively returns the part of the purchase price linked to earlier accrued income.

The economic idea is simple: two investors should not both be treated as if they owned the same income for the full period when one of them bought in halfway through.

Which tax year contains the distribution?

For the ordinary UK AIF rules, the distribution date is the key date for the distribution period. HMRC's offshore-fund guidance says distributions to income-tax investors are taxed for the year of assessment in which the distribution is made. This is why the tax year can differ from the period in which the fund earned the underlying dividends or interest.

Accumulation units need extra care because income can be credited to the capital part of the scheme rather than paid out in cash. The tax paperwork should identify the amount that has been treated as distributed or reportable.

Use the tax voucher, not just the bank entry

A bank statement may show only one cash amount. The fund's tax voucher or annual report can split the amount into dividend, interest, equalisation or other components. Those components can have different tax treatment.

How equalisation affects a later sale

Suppose an investor buys units with an equalisation amount included in the purchase price. When that equalisation is returned, HMRC says the amount is deducted from the units' base cost for CGT purposes. A lower base cost means a later gain can be larger than it would have been if the equalisation had simply been ignored.

What to check before filing

Distribution period end date.
Contractual distribution date.
Whether the fund is UK authorised or an offshore reporting fund.
Whether units are Group I or Group II.
The income and equalisation split shown on the fund tax voucher.
Any later disposal of the units where the equalisation amount affects cost.

Keep the tax voucher with the acquisition record

Distribution and equalisation questions are much easier to answer when the fund tax voucher is kept with the original purchase record. The voucher can identify the relevant distribution date and show the split between the income element and equalisation. For an investor who later sells the units, that record can also explain why the cost used for Capital Gains Tax is not simply the original contract amount.

Offshore reporting funds need an additional check because HMRC applies reporting-fund distribution rules to the year in which the relevant distribution is made. Do not substitute the cash-payment date for the fund’s tax documentation.

Worked example

Illustrative example: An investor buys Group II units during a distribution period. The fund later pays a total distribution of £100, of which the tax voucher identifies £25 as returned equalisation and £75 as the income element.

The income element is £100 − £25 = £75.
The £25 equalisation is a capital receipt rather than income under HMRC's equalisation treatment.
If the £25 equalisation related to the acquisition cost, the later CGT base cost would be reduced by £25.
If the original purchase cost were an illustrative £1,000, the adjusted base cost would be £1,000 − £25 = £975.

The exact reporting depends on whether the fund is an authorised investment fund, an offshore reporting fund, or another structure. Use the fund's tax voucher to identify the relevant amounts and dates.

What date counts for a fund distribution for UK tax?#

For an authorised investment fund, HMRC defines the distribution date by the fund documents or, if none is specified, the last day of the distribution period. Offshore reporting-fund rules also use the year in which the distribution is made, so the fund's tax paperwork is important.

Is fund equalisation taxable income?#

Returned equalisation is generally treated as a capital receipt rather than income under HMRC's authorised-investment-fund treatment. It is not simply extra dividend or interest. The amount can instead reduce the cost of the units for a later capital-gains calculation. The fund paperwork should be retained for as long as the units may create a later tax calculation or disposal record.

What is the difference between Group I and Group II units?#

Group I units are held throughout the distribution period. Group II units are bought part-way through it. Group II investors can receive both the income accrued while they held the units and an equalisation amount linked to income that had accrued before purchase.

Does the date the cash reaches my bank determine the tax year?#

Not necessarily. The fund's distribution date and tax treatment determine the relevant tax year, not simply when you notice the cash in your bank account. Check the fund's distribution statement or tax voucher for the official date and breakdown. The fund paperwork should be retained for as long as the units may create a later tax calculation or disposal record.

Can equalisation change my capital gains tax calculation?#

Yes. HMRC says returned equalisation is a capital receipt that should be deducted from the cost of the units for CGT purposes. That can reduce the base cost and therefore increase a later chargeable gain when the units are sold.

Do accumulation units create a tax date even when I get no cash?#

They can. For authorised funds, an amount can be credited to the capital part of the scheme property on behalf of an investor holding accumulation units. The tax paperwork should show the amount treated as distributed or reportable even though cash was not paid out.

What should I keep for a fund distribution tax return?#

Keep the fund tax voucher, distribution statement, purchase contract and any equalisation schedule. Together they show the distribution date, the income component and any capital equalisation that may need to be reflected in the units' cost for a later disposal.
