What to sort out before you invest
Investing works best with money you can leave alone for years. Before you start, it helps to have a cash emergency fund and a clear idea of when you might need the money. Our beginner's guide explains the checks MoneyHelper suggests and why they matter.
Accounts come before investments
In the UK, the account you invest through decides how your money is taxed. Stocks and shares ISAs shelter income and gains from tax, pensions add tax relief on what you pay in, and general investment accounts have no limits but can be taxable. Choosing the account first makes everything after it simpler. Start with how ISAs work.
Why costs and time matter most
You can't control what markets do, but you can control how long you invest for and how much you pay in fees. Both compound over the years. Use our compound interest calculator to see how starting earlier, or paying lower fees, changes the result on your own numbers.
What tax do you pay on investments?
Inside an ISA or a pension, you pay no tax on investment growth or income while it stays in the account. Outside them, in a general investment account, two taxes usually apply in 2026/27. Profits above the £3,000 Capital Gains Tax allowance are taxed at 18% or 24%, depending on your income. Dividends above the £500 dividend allowance are taxed at 10.75% for basic-rate taxpayers, 35.75% at the higher rate and 39.35% at the additional rate. That's why most beginners start with an ISA: up to £20,000 a year goes in without any of these taxes applying. Our guide to tax on investments explains the rules and when to tell HMRC. Our guide to stocks and shares ISAs versus cash ISAs explains how to choose between the two.
How do you know a firm is safe to use?
Before you hand money to any investment firm, look it up on the FCA Financial Services Register and make sure the contact details match the ones the firm gave you. If an authorised investment firm fails and can't return your investments, the Financial Services Compensation Scheme may pay up to £85,000 per person, per firm. That is separate from the £120,000 limit for cash in a bank. Neither protects you from investments falling in value. Unsolicited calls, guaranteed high returns and pressure to act quickly are classic signs of a scam, and the FCA's ScamSmart tool lets you check an offer before you go ahead.

Our guides explain how things work so you can make informed decisions or ask better questions. They aren't personal advice.
