What is a general investment account?

A general investment account (GIA), also sometimes called a share dealing account or an investment account, is a standard brokerage account with no tax wrapper. You can hold the same range of assets as in an ISA, including UK and international shares, ETFs, investment trusts and bonds, but returns are subject to the normal UK tax framework. Capital gains above the £3000 annual allowance are liable to CGT; dividends above the £500 allowance are liable to dividend tax; and there is no cap on how much you can invest in any given year.

The terms 'general investment account', 'share dealing account' and 'investment account' are used interchangeably by different providers. The lack of an annual contribution limit is the primary advantage of a GIA over an ISA for investors who want to invest more than £20,000 per year. The trade-off is that returns are taxed above the relevant annual allowances, which have been significantly reduced in recent years.

What is a stocks and shares ISA?

A stocks and shares ISA is a tax-efficient investment account. You can hold shares, ETFs, investment trusts, bonds and cash funds within it, and any returns, whether capital gains, dividends or interest, are completely free from UK income tax, dividend tax and capital gains tax. The wrapper is permanent: there is no limit on how large an ISA can grow, and there is no time limit on how long the tax-free protection lasts. You can contribute up to £20,000 per tax year across all your ISAs combined. Stamp duty, however, still applies.

One important change to note: from April 2027, the government will limit Cash ISA contributions to £12,000 per year for those under 65, while the overall £20,000 allowance remains in place. This means the 2026/27 tax year is the last one in which those under 65 can put the full £20,000 into a Cash ISA. Stocks and shares ISAs are unaffected by this restriction.

Tax treatment in a GIA: what you need to know for 2026/27

Investing outside an ISA triggers the normal UK tax framework on returns. The three main taxes to be aware of are capital gains tax, dividend tax and income tax on interest, all of which have changed for 2026/27.

1. Capital gains tax (CGT)
2. Dividend tax
3. Stamp duty reserve tax (SDRT)

Capital gains tax (CGT)

When you sell shares or other assets in a GIA at a profit, you may owe CGT on the gain above the £3000 annual allowance. For 2026/27, CGT rates on shares remain at 18% for basic-rate taxpayers and 24% for higher and additional-rate taxpayers. The allowance has been sharply reduced in recent years: it was £12,300 as recently as 2022/23. Losses crystallised in a GIA can be used to offset gains, which is an advantage the ISA does not provide.

Dividend tax

Dividends received in a GIA above the £500 annual dividend allowance are subject to dividend tax. For 2026/27, the rates increased by 2 percentage points: basic-rate taxpayers now pay 10.75% (up from 8.75%), higher-rate taxpayers pay 35.75% (up from 33.75%), and additional-rate taxpayers pay 39.35% (unchanged). For a higher-rate taxpayer receiving £5,000 in dividends outside an ISA, the tax bill on dividends above the £500 allowance is now £1608.75, up from £1,518.75 the year before.

Stamp duty reserve tax (SDRT)

Both ISAs and GIAs are subject to 0.5% SDRT when buying UK-listed shares electronically. This applies to both accounts equally and is collected automatically by your broker at the point of purchase. It does not apply to the purchase of most ETFs.

What can you hold in each account?

Both accounts can hold a wide range of assets: UK and international shares, investment trusts, corporate bonds, government bonds (gilts), ETFs and cash funds. The ISA has one restriction the GIA does not: investments must be held on a recognised stock exchange for ISA eligibility. Most FTSE-listed stocks, US stocks, and ETFs listed on major exchanges are ISA-eligible. Stocks listed only on smaller, unrecognised exchanges are generally not.

ETFs are a common holding in both accounts. A global ETF tracking the MSCI World index, for example, is ISA-eligible and generates both dividends and capital growth that would otherwise be taxable in a GIA. 

There are key distinctions to be made when it comes to index funds vs ETFs, in terms of how accumulating and distributing versions of these products interact with tax planning. 

One important asymmetry: losses made on investments inside an ISA cannot be used to offset capital gains elsewhere. If you hold a position that has fallen significantly in value, it can sometimes make sense to hold it in a GIA rather than an ISA, so that crystallising the loss can offset gains on other positions. This is a general principle rather than specific advice.

When to use an ISA vs a general investment account

The right approach depends on how much you invest each year, your tax position and whether you value flexibility over tax efficiency. Here is a framework:

Use the ISA first if:

• You invest up to £20,000 per tax year, since the ISA can shelter all of it from tax permanently
• You are a higher or additional-rate taxpayer, since the tax saved on dividends and gains is more significant for you
• You expect your investments to grow substantially over time and want gains to compound free of CGT
• You hold income-generating assets such as dividend-paying shares or bond funds, where the dividend and interest tax savings are meaningful
• You want to simplify your tax affairs: ISA returns do not need to be reported to HMRC

Use a GIA alongside your ISA if: 

• You want to invest more than £20,000 in a given tax year 
• You hold assets that are not ISA-eligible, such as stocks listed on smaller exchanges 
• You have realised losses in the GIA that you want to use to offset gains 
• You want the ability to crystallise gains each year up to the £3000 CGT allowance without tax, in a way that can systematically reduce a larger GIA position 
• You invest predominantly for capital growth rather than income, and your annual gains are likely to stay below the £3000 allowance 

The Bed and ISA strategy

Investors who already hold shares in a GIA can move them into an ISA using a process called Bed and ISA: sell the shares in the GIA, crystallising any gain or loss, and immediately repurchase the same shares inside the ISA. The gain on the sale is subject to CGT in the normal way, but future growth and income from the position is then sheltered permanently. This is worth considering for investors with large GIA holdings they want to migrate into the ISA wrapper over time.

An example of an ISA vs GIA in action

To illustrate the difference, consider two hypothetical investors, both higher-rate taxpayers, who invest £20,000 at the start of the 2026/27 tax year in a broadly diversified global equity ETF that grows 8% per year and yields 2% in dividends annually.

This is a simplified illustration using fixed assumptions and is not a forecast or recommendation. Tax treatment depends on individual circumstances and may change. The key point is the compounding effect of permanent tax-free growth in an ISA versus recurring CGT and dividend tax exposure in a GIA.
