- Dividend tax on investments in a general investment account will increase from April 2026
- Savings income tax rates will rise from April 2027.
Invest monthly
Regular monthly payments can make a difference, helping to smooth out market ups and downs. You set up, adjust or pause them whenever you wish in Online Service.
Consolidate your ISAs
Move your stocks and shares or cash ISAs into one easy-to-manage pot.
It won’t impact your annual limit, but check for exit fees before you switch.
Remember, the value of investments can go up and down, so you may get back less money than you put in. Tax depends on your individual circumstances and the regulations may change in the future.
Can your savings work harder?
Cash is good for short-term goals, where you need risk free savings with easy access. For long-term goals, cash savings may not keep up with inflation.
Historically, stock markets have generally grown more than cash savings over the long term. While markets have ups and downs, time in the market matters.

Questions and answers
How much can I invest in an ISA this tax year?
Each tax year, the annual ISA allowance is £20,000 across all your ISAs — not per account.
If I don’t use my ISA allowance, can I roll it over into next year?
No — if you don’t use your ISA allowance in a tax year, you lose it. It doesn’t carry forward.
Can I have more than one ISA at the same time?
Yes — you can open more than one ISA in the same tax year, including two or more of the same type (e.g., multiple Stocks & Shares ISAs).
However, you can’t contribute more than £20,000 in total across them in one tax year.
Can ISA growth push me over my allowance?
No — your allowance only applies to what you put in, not what it grows into. Any returns inside your ISA are not subject to income or capital gains tax.
What happens if I accidentally contribute more than £20,000?
If you go over the allowance, you can contact HMRC — or they will contact you and let you know how they plan to adjust for the overpayment.
Can I inherit a partner’s ISA allowance?
Yes — spouses and civil partners can inherit an Additional Permitted Subscription (APS) allowance equal to the value of the ISA held by the partner who passed away.
How are ISA rules changing in future years?
From April 2027, the annual allowance on cash ISAs will drop from £20,000 to £12,000 for under-65s — there’s no change for over-65s. Read more about the 2025 November Budget.
Does transferring an ISA affect my allowance?
No — ISA transfers don’t reduce your annual allowance, even if you transfer the full balance.
