The General Investment Account is the wrapper with no wrapper. No tax relief going in. No tax-free growth. No tax-free withdrawals. No annual limits. No access restrictions. No special rules. Just you, your investments, and HMRC watching every move.
So why would anyone use one? Because sooner or later, most investors run out of ISA and pension allowance. And when you do, the GIA is where everything else goes.
It’s also the gateway to account types that don’t exist inside tax wrappers: margin accounts, futures accounts, CFD accounts, and spread betting accounts. For experienced traders and investors, the GIA world is where the full toolkit lives.
What Is a GIA?
A General Investment Account is a standard, taxable investment account. You open one on a platform or with a broker, deposit money, and invest in whatever that platform offers. There are no contribution limits, no withdrawal restrictions, and no minimum holding periods.
The simplicity is the point. The tax bill is the price.
What You Can Hold in a GIA
A GIA can hold anything a Stocks & Shares ISA can hold, and usually more:
- UK and international shares (on any recognised exchange)
- Funds (OEICs, unit trusts)
- ETFs
- Investment trusts
- Government and corporate bonds
- Gilts (index-linked and conventional)
- Structured products
- REITs
- AIM shares
- Some platforms allow: crypto ETNs, commodities, options, warrants
The investment range depends on the platform. A basic platform like Vanguard offers only Vanguard funds. A full-service broker like Interactive Brokers or Saxo offers tens of thousands of instruments across global exchanges.
Tax Treatment (2026/27)
This is the bit that matters. In a GIA, you pay tax on three things: dividends, interest, and capital gains.
Dividends
| Tax Band | Rate (2026/27) |
|---|---|
| Dividend allowance | First 500 tax-free |
| Basic rate | 10.75% ¹ |
| Higher rate | 35.75% ¹ |
| Additional rate | 41.35% ¹ |
¹ Increased by 2 percentage points from April 2026 (previously 8.75%, 33.75%, 39.35%)
Dividends within ISAs and pensions are completely tax-free. In a GIA, only the first 500 escapes. Above that, the rates are punchy, especially for higher-rate taxpayers. A 10,000 dividend to a higher-rate taxpayer costs roughly 3,400 in tax. The same dividend in an ISA costs zero.
Interest (Bonds, Gilts, Cash)
| Tax Band | Rate |
|---|---|
| Personal Savings Allowance | 1,000 / 500 / 0 ² |
| Basic rate | 20% |
| Higher rate | 40% |
| Additional rate | 45% |
² 1,000 for basic-rate taxpayers, 500 for higher-rate, zero for additional-rate
Interest from bonds, gilts, and cash holdings in a GIA is taxed as savings income at your marginal rate, after the Personal Savings Allowance.
Capital Gains Tax
| Tax Band | Rate |
|---|---|
| Annual exemption | First 3,000 tax-free |
| Basic rate | 18% |
| Higher rate | 24% |
CGT is only triggered when you sell (or gift to a non-spouse). Holding an investment that’s gone up in value doesn’t create a tax bill. Selling does. This gives you control over timing.
CGT planning tips:
- Use your 3,000 annual exemption every year (it doesn’t carry forward)
- Bed and ISA: sell GIA holdings and repurchase in your ISA to shelter future growth
- Bed and SIPP: same idea but into your pension (with tax relief on the contribution)
- Spouse transfers: transferring assets to a spouse is not a taxable event. Use their exemption too
- Harvest losses: sell losing investments to crystallise a capital loss, which offsets gains now or in future years
- Losses do carry forward indefinitely. Gains exemptions don’t
Stamp Duty
Buying UK shares in a GIA triggers Stamp Duty Reserve Tax (SDRT) at 0.5%. Buy 10,000 of Tesco shares and you pay 50 in stamp duty before you’ve made a penny. This applies in ISAs and SIPPs too, but it’s worth noting.
ETFs domiciled in Ireland (which most popular ETFs are) are exempt from SDRT. One reason ETFs are popular for cost-conscious investors.
Custodians, Nominees, and How Your Assets Are Held
When you buy investments through a platform, you almost certainly don’t appear on the company’s share register. Instead, your assets are held by a nominee company or custodian on your behalf.
How Nominee Accounts Work
- The platform creates a nominee company (a legal entity whose only job is holding client assets)
- Your shares, funds, and other investments are registered in the nominee’s name, not yours
- You remain the beneficial owner (the investments are yours, the nominee just holds the legal title)
- FCA rules require client assets to be held separately from the platform’s own assets (client asset segregation)
- If the platform goes bust, your investments should be identifiable and returnable to you (though it may take time)
Custodians
Larger platforms use third-party custodians (specialist firms whose entire business is safekeeping assets). Examples include:
- BNY Mellon (one of the world’s largest custodians)
- Citibank
- Northern Trust
- State Street
- J.P. Morgan
The custodian physically holds the assets (or the electronic records of ownership) on behalf of the platform’s clients. This adds a layer of protection: even if the platform fails, the custodian still has your stuff.
CREST and Direct Holding
For UK shares, ownership is recorded in the CREST system (operated by Euroclear). Most retail investors hold through nominees. However, some platforms (notably Interactive Investor and a few others) offer personal CREST accounts or certificated holdings where shares are registered directly in your name.
Direct holding means:
- You appear on the company’s share register
- You receive company communications directly
- You can vote at AGMs without going through the platform
- Your shares are unambiguously yours (no nominee complication if the platform fails)
The downside: it’s slower, more paperwork, and not all platforms support it. For most people, nominee holding is perfectly fine.
FSCS Protection
The Financial Services Compensation Scheme covers up to 85,000 per person per firm if an FCA-authorised investment firm fails. This protects your cash held with the platform (uninvested cash). Your investments themselves are held separately by the nominee/custodian and should be returned to you even if the platform goes bust, though the process can take months.
Spread your uninvested cash across different firms if you hold large amounts.
GIA Providers and Platforms
The same platforms that offer ISAs and SIPPs also offer GIAs. The account structure is simpler (no HMRC reporting for ISA compliance), so GIAs are available everywhere.

Account Types Beyond a Standard GIA
A standard GIA holds shares, funds, and bonds. But the broader brokerage world offers specialist account types for different instruments. These are all taxable accounts (no wrapper benefits), but they each serve different purposes.
Margin Account
A margin account lets you borrow money from your broker to buy investments, using your existing holdings as collateral. This is leverage: you control a larger position than your cash would normally allow.
- How it works: if you have 10,000 in shares, the broker might lend you another 5,000-10,000 to invest. You pay interest on the borrowed amount
- Margin call: if your holdings fall in value, the broker can demand more collateral or liquidate your positions to repay the loan. This can happen automatically and without warning
- Who uses them: experienced investors who want to increase their market exposure
- Tax treatment: gains and losses are taxed as normal CGT. Interest on the margin loan may be deductible in some circumstances
- Available from: Interactive Brokers, Saxo, IG, and other full-service brokers
Margin accounts amplify everything. Gains are bigger. Losses are bigger. And a margin call at the worst possible moment can force you to sell at the bottom. This is not for beginners.
CFD Account
Contracts for Difference. You don’t buy the underlying asset. You enter a contract with the broker that pays (or costs) the difference between the opening and closing price.
- Leverage: FCA caps at 30:1 for major forex, 20:1 for indices, 10:1 for commodities, 5:1 for shares, 2:1 for crypto
- Short selling: you can profit from falling prices as easily as rising ones
- Tax: profits subject to CGT at 18%/24%. Losses can be offset against other gains
- No stamp duty (you don’t own the underlying asset)
- Overnight financing charges apply on leveraged positions held past the trading day
- 75-80% of retail CFD accounts lose money (FCA data)
- Available from: IG, CMC Markets, Saxo, Plus500, eToro, Pepperstone
Spread Betting Account
Unique to the UK and Ireland. Structured as a bet, not an investment.
- Tax-free profits (HMRC classifies it as gambling, so no CGT and no stamp duty)
- Tax-free losses (but this means losses cannot be offset against other gains)
- Leverage: same FCA limits as CFDs
- Available from: IG, CMC Markets, Spreadex, City Index, Pepperstone
- Not available: in ISAs, SIPPs, or from Interactive Brokers (IBKR doesn’t offer spread betting)
Spread betting is the only way to speculate on financial markets completely tax-free in the UK. The catch is that the same statistics apply: most retail accounts lose money.
Futures Account
For trading actual exchange-traded futures contracts (not CFDs that mimic futures).
- Exchange-traded: your orders go to real exchanges (CME, ICE, Eurex)
- Standardised contracts: each contract has a defined size, tick value, and expiry
- Margin-based: you deposit a fraction of the contract’s notional value
- Tax: CGT at 18%/24% on profits. Losses offsettable
- Available from: Interactive Brokers (the main option for UK retail investors), Saxo
- Not available: from most mainstream UK platforms (HL, AJ Bell, ii don’t offer futures)
Futures give you direct access to commodity markets (oil, gold, wheat), interest rate markets, and equity index markets. They’re professional instruments with professional-level risk.
Options Account
For trading listed options on shares, indices, and ETFs.
- Exchange-traded options (not to be confused with CFD-based “options” offered by some brokers)
- Calls and puts with defined strike prices and expiry dates
- Tax: CGT at 18%/24%. Premiums paid for options that expire worthless are capital losses
- Available from: Interactive Brokers, Saxo, IG (limited), tastytrade (accessible via UK accounts)
- Strategies: covered calls, protective puts, spreads, and more complex multi-leg strategies
Forex Account
For trading currency pairs (GBP/USD, EUR/GBP, etc.).
- Highly leveraged (up to 30:1 for major pairs under FCA rules)
- Tax: CGT on spot forex trades. Spread betting on forex is tax-free
- Available from: most CFD/spread betting brokers, Interactive Brokers, Saxo
- 24-hour market (Sunday evening to Friday evening)
Account Type Comparison

¹ Futures are contracts, not ownership. Some are cash-settled, but others will go through to delivery (you don’t want to take delivery of 1,000 barrels of oil)
² HMRC classifies spread betting as gambling. No CGT on profits, but no loss relief either
³ 0.5% SDRT on UK share purchases. Irish-domiciled ETFs exempt
⁴ Limited short selling possible through stock borrowing, but practically difficult for retail investors
When to Use a GIA
After you’ve filled your ISA and pension. That’s the simple answer.
More specifically:
- You’ve used your 20,000 ISA allowance and still have money to invest
- You’ve maxed your pension contributions (or don’t want to lock money away until 55/57)
- You need flexible access with no restrictions on withdrawals
- You want to hold assets unavailable in ISAs/SIPPs (certain international shares, derivatives, structured products)
- You’re doing bed-and-ISA (holding investments temporarily before transferring into ISA each year)
- You’re trading actively using CFDs, spread betting, futures, or options
- Business or corporate investing (companies can’t hold ISAs or SIPPs)
GIA vs ISA vs Pension: A Quick Reminder
| GIA | ISA | Pension | |
|---|---|---|---|
| Tax relief in | ❌ | ❌ | ✅ |
| Tax-free growth | ❌ | ✅ | ✅ |
| Tax-free out | ❌ | ✅ | ⚠️ ⁵ |
| Annual limit | None | 20,000 | 60,000 |
| Access | Anytime | Anytime | 55/57+ |
⁵ 25% tax-free lump sum; remainder taxed as income
The GIA is always the last resort. But it’s a perfectly functional last resort. If you’re investing beyond your allowances, a GIA with good tax planning (using your CGT exemption, bed-and-ISA, loss harvesting, spouse transfers) can still be highly efficient.
The Bottom Line
The GIA is the un-wrapped wrapper. No tax advantages, no restrictions, no limits. It’s where you invest once the ISA and pension are full, where you hold specialist instruments that don’t fit in tax wrappers, and where the full range of trading accounts lives.
The tax treatment is real: dividends are taxed at 10.75-41.35%, interest at 20-45%, and gains at 18-24% above a 3,000 exemption. But with good planning, the impact can be managed. Use your annual exemptions. Bed and ISA regularly. Harvest losses. Use your spouse’s allowances.
And if you find yourself paying significant tax on GIA investments, it’s a sign you’re doing well. Worse problems to have.
All figures are for the 2026/27 tax year.
