UK Tax & National Insurance Comprehensive Guide 2026
Complete walkthrough of PAYE Income Tax bands, Class 1 NI thresholds, Scottish rates, and student loan deductions for the 2026/27 tax year.
Understanding PAYE Income Tax in 2026/27
UK employees pay Income Tax through Pay As You Earn (PAYE). For the 2026/27 tax year, the Personal Allowance remains the foundation of every calculation — earnings below this threshold incur no Income Tax. Above it, England, Wales, and Northern Ireland use standard UK bands (basic 20%, higher 40%, additional 45%), while Scotland applies its own devolved band structure.
uktaxcalculation synchronizes every city page against published HMRC thresholds weekly. When you enter a gross salary, the engine computes band-by-band tax, applies Personal Allowance taper for high earners above £100,000, and outputs weekly, monthly, and annual net figures.
Class 1 National Insurance
National Insurance is UK-wide — Scottish residents pay the same Class 1 employee NI as England. The main rate applies between the Primary Threshold and Upper Earnings Limit; an additional 2% rate applies above the UEL. Employer NI is separate and not included in take-home calculations on this platform.
Student loan repayments (Plans 1, 2, 4, and Postgraduate) are deducted after tax and NI, calculated as a percentage of earnings above plan-specific thresholds.
