UK Tax Codes Explained (2026/27): 1257L, BR, K, 0T & W1/M1
What every part of your tax code means on a UK payslip — the number (your tax-free allowance ÷ 10), the letters (L, M, N, T, 0T), the flat-rate codes (BR, D0, D1), K codes, NT, the W1/M1 emergency marker and the S / C prefixes — and exactly how each one changes your take-home pay.

Fiscal Drag 2026/27: What Frozen Tax Thresholds Really Cost You
The Personal Allowance and higher-rate threshold have been frozen since 2021/22. Had they risen with CPI inflation they'd be ~28% higher — £16,070 and £64,280, not £12,570 and £50,270. We use the SalaryGrid engine to quantify exactly what that 'stealth tax' costs at every salary, with the September-CPI methodology shown in full.

Universal Credit savings limit — the £6,000 tariff and £16,000 cliff
How much savings can you have on Universal Credit? Three asset tiers: under £6k (ignored), £6k–£16k (tariff income at £4.35 per £250 above the floor), and over £16k (absolute cliff-edge lockout).

How the Universal Credit Taper Rate Works (2026/27): The 55% Math
The single 55% taper rate doesn't apply to gross salary — it bites into your net earnings above the Work Allowance. A worked example of how a £1,004/mo paycheck on a £404 housing-linked allowance trims the UC award by £330 (not the full £552).
