For millions of Brits, fiscal drag is one of the biggest sources of financial pain.
Your salary goes up, but income tax thresholds stay frozen. So more of your pay gets pulled into tax.
Example: your salary rises from £40,000 to £45,000. That’s £5,000 more income, but at 20%, up to £1,000 of that increase could go straight to income tax, before NI and other deductions.
