ISA & Pension Rules
Maximizing your tax-free investment allowances
Critical: Cash ISA vs Stocks & Shares ISA
Millions of UK residents are losing money by keeping their savings in Cash ISAs instead of investing in Stocks & Shares ISAs. Here's why:
Cash ISA (Savings)
- • Interest: 3-5% per year
- • Inflation: 2-4% per year
- • Real return: 0-2% or negative
- • Your money loses purchasing power
Stocks & Shares ISA (Investing)
- • Returns: 7-10% per year (historical)
- • Inflation: 2-4% per year
- • Real return: 4-7%
- • Your money builds real wealth
The bottom line: Cash ISAs are great for emergency funds and short-term savings (1-3 years). But for long-term wealth building, Stocks & Shares ISAs historically deliver far better results. See the calculator to understand the impact.
Why ISAs and Pensions Matter
ISAs (Individual Savings Accounts) and pensions are the UK's most powerful tax-efficient investment vehicles. ISAs offer tax-free growth and withdrawals. Pensions offer tax relief on contributions plus tax-free growth. Together, they can save you tens of thousands in tax over your lifetime.
Understanding the rules helps you maximize your allowances and build wealth faster. Every pound invested tax-efficiently grows faster than a taxable investment.
