Calculating your wrapper comparison…

Illustrative ending value before tax and charges

£107,201

Uses your monthly contributions, price-growth rate and distribution yield; distributions are reinvested. It excludes GIA tax, wrapper rules and provider charges. The full UK comparison replaces this estimate when the calculation service responds.

Total planned contributions over 10 years

£70,000

Initial investment plus monthly contributions, before growth, distributions or tax. This is an input total, not a projected account value.

The gross value above is provisional; the wrapper projection will replace it when the UK calculation service returns values matching these inputs.

How to compare wrappers

A GIA is modelled as taxable; an eligible ISA is modelled as sheltered; SIPP values show accumulation before any withdrawal tax. The selected tax band is an assumption, not a calculation of your total income-tax position or Scottish bands. Enter annual amounts for other dividends, interest and gains; other gains reduce the modelled CGT exemption, and your complete tax position is not recalculated. This simplified 2026/27 scenario is not a tax return: fund reporting status is not checked, and wrapper eligibility, contribution limits, charges, losses and access are not modelled.

About this calculator

Compare an entered investment plan across a taxable General Investment Account (GIA), an ISA and a SIPP using the same contribution, growth and distribution assumptions.

The model projects annual wrapper balances from the upfront amount, contributions added at the start of each month, price-growth assumption and distribution yield. For a GIA it estimates distribution tax during the holding period and capital gains tax only on the modelled final sale. If reinvested distributions leave no cash to pay that tax, the model deducts it from the investment balance but does not separately calculate CGT from any units sold to fund the payment. ISA and SIPP accumulation are shown before account-specific charges, and SIPP value is before withdrawal tax.

Tax bands, fund distribution category and other annual income/gains are user-entered assumptions. The model does not identify reporting-fund status, calculate your complete income-tax or CGT position, test wrapper eligibility or contribution limits, or model access, losses and provider charges. Check the fund documents and current HMRC guidance before using the illustration for a decision.

UK ETF tax FAQs

Do I pay tax on ETF distributions in a GIA if I reinvest them?

Usually, yes. Reinvesting a distribution does not by itself defer the tax: in a taxable GIA, the distribution or relevant reported income can still be taxable. The exact treatment depends on the fund structure, reporting-fund status and whether the income is treated as dividend, interest or another category.

Does this ETF tax calculator check whether my fund is a reporting fund?

No. You must check the fund’s reporting status and any Excess Reportable Income information with the fund manager or HMRC reporting-fund list. A reporting offshore fund can require tax on reportable income even when it was not distributed; a non-reporting fund can have less favourable income treatment on disposal.

Why is SIPP shown as tax-free in the comparison?

The comparison models the accumulation phase inside a SIPP, where investment income and gains are generally not taxed in the same way as a GIA. It does not model taxable pension withdrawals, the tax-free lump-sum rules, annual allowance, contribution relief, provider charges or access restrictions, so SIPP is not universally tax-free overall.

Does the calculator calculate my full UK income-tax position?

No. It uses a selected tax band and simplified inputs for a scenario comparison. It does not determine your complete Personal Allowance, Scottish bands, pension relief, losses, fund classification, foreign tax credit, dividend reporting or Self Assessment position.

What is the difference between accumulating and distributing ETFs for UK tax?

A distributing ETF pays income to you. An accumulating ETF reinvests income inside the fund, but that does not automatically make the income tax-free in a GIA: reporting-fund Excess Reportable Income may still need to be reported. Inside an ISA, eligible income and gains are generally sheltered; outside an ISA, wrapper and fund classification matter more than the ACC/DIST label alone.

How does the CGT annual exempt amount apply to ETF disposals in 2026/27?

The individual CGT annual exempt amount is £3,000 for 2026/27. It applies to your total chargeable gains for the tax year, not separately to each ETF. Gains above the available exemption are generally taxed at 18% or 24% for individuals, depending on the taxpayer’s circumstances and the type of asset.

How does the UK ETF tax calculator compare GIA, ISA and SIPP?

It applies the same contribution, growth, yield and time assumptions to each wrapper, then estimates the tax drag for the GIA and the accumulation-phase shelter for ISA and SIPP. It is a scenario comparison, not a recommendation: access, contribution limits, pension withdrawal tax, fees, fund status and investment risk are not fully equivalent across wrappers.

How much tax do I pay on VWRP or VWRL in the UK?

A ticker alone is not enough to calculate the tax. Check whether the specific share class is accumulating or distributing, whether it is a reporting fund, its reportable income, your wrapper and your other income and gains. This calculator does not fetch fund-specific reporting-fund data for VWRP, VWRL or any other ETF.

Is an accumulating ETF automatically better than a distributing ETF?

No. The choice depends on your wrapper, need for cash income, fund structure, reporting status, fees, tracking difference and tax position. An accumulating fund can simplify reinvestment, but in a GIA it can still create reportable income; an ISA normally changes the tax comparison more materially than the ACC/DIST label.

What is the effective tax rate on a UK ETF investment?

There is no reliable single percentage for every investor. The result depends on wrapper, income band, fund classification, distributions, timing of disposals, annual exemptions, losses and fees. The calculator’s effective figure is only the tax paid in its simplified projection divided by the modelled investment outcome.

How does the dividend allowance affect ETF investing in 2026/27?

The dividend allowance is £500 for 2026/27. Dividends above the available allowance are generally taxed at 10.75%, 35.75% or 39.35%, depending on the taxpayer’s dividend rate. The allowance is shared across your dividend income, not granted separately for each ETF or account.

Is ETF CGT charged at 10% or 20% in the UK?

For most individual disposals from 6 April 2026, the standard CGT rates are generally 18% and 24%, not the older 10% and 20% rates. The applicable rate depends on your taxable income, the type of gain and the rules for the asset. This calculator uses a simplified tax-band assumption and does not prepare a CGT return.
