Does HMRC monitor personal savings and bank accounts?
Yes. UK banks and building societies submit annual interest and dividend reports directly to HMRC under statutory data-sharing rules. HMRC uses these automated reports to adjust PAYE tax codes or issue Self Assessment tax demands if your untaxed savings interest exceeds statutory allowances.
How much savings interest can you earn tax-free in the UK?
Under the Personal Savings Allowance, basic-rate (20%) taxpayers can earn up to £1,000 of savings interest per year tax-free. For higher-rate (40%) taxpayers, the allowance is £500 per year. Additional-rate (45%) taxpayers receive no tax-free savings allowance.

Under UK pensions rules, you can normally take up to 25% of your defined contribution pension pot as a tax-free lump sum, capped at the statutory Lump Sum Allowance of £268,275. Any remaining pension withdrawals or annuities are taxed as normal earnings at your marginal income tax rate.
