With savings rates at 4-5% and HMRC automatically tracking interest paid by banks, millions of UK savers are breaching their tax-free threshold without even knowing it. Here's exactly how the system works — and how to protect yourself. Updated April 2026 The UK Savings Tax Thresholds 2026/27
These thresholds have not changed in 2026/27. The Personal Savings Allowance was introduced in 2016 and has been frozen since — but with savings rates now at 4-5%, far more people are breaching it than in the low-rate era. How Much Do You Need in Savings to Breach the Threshold?
Source: MoneySavingExpert, rates correct as of 31 March 2026. If you have savings above these thresholds, HMRC may already be adjusting your tax code. How HMRC Collects Savings TaxYou do NOT need to tell HMRC about savings interest if you're a PAYE employee or pensioner — banks automatically report all interest paid to HMRC each year. HMRC then adjusts your tax code for the following year, reducing your personal allowance to collect any tax owed. If you're self-employed, you declare savings interest via your Self Assessment tax return. This system means many savers receive unexpected tax code changes or letters without realising they've breached their threshold. If your tax code looks odd, check your savings interest total for the previous year. How to Stay Under Your Savings Tax Threshold
