How to Calculate Your Salary After Tax:
UK & US Guide

8 min read · Tax · Updated July 2026

Your gross salary is the number in your job offer. Your take-home pay — or "net salary" — is what actually lands in your bank account. The gap between the two surprises most people, and understanding exactly where it goes helps you budget accurately and find legal ways to keep more.

UK Salary After Tax: How It Works

UK employees pay two main deductions: Income Tax and National Insurance contributions (NICs). Your employer also deducts these via PAYE (Pay As You Earn) before paying you.

UK Income Tax Bands (2026/27)

BandIncome RangeRate
Personal Allowance£0 – £12,5700%
Basic Rate£12,571 – £50,27020%
Higher Rate£50,271 – £125,14040%
Additional RateOver £125,14045%

Note: The personal allowance is reduced by £1 for every £2 you earn over £100,000, reaching zero at £125,140.

UK Example: £45,000 Salary

Gross Salary: £45,000

Income Tax:
· £0–£12,570 = £0 (personal allowance)
· £12,571–£45,000 = £32,430 × 20% = £6,486
Total tax: £6,486

National Insurance:
· £12,571–£45,000 = £32,430 × 8% = £2,594

Take-home pay: £45,000 − £6,486 − £2,594 = £35,920/year (£2,993/month)

Things That Reduce Your UK Tax Bill

💡 The £100,000 trap: Earning £100,001 costs you your personal allowance — the effective marginal tax rate on earnings between £100,000 and £125,140 is 60%. Pension contributions are the most powerful tool to avoid this.

US Salary After Tax: How It Works

US tax is more complex because you pay Federal income tax, FICA (Social Security + Medicare), and potentially state income tax — all of which vary by filing status and location.

US Example: $70,000 Salary (Single, No State Tax)

Gross Salary: $70,000 (standard deduction of $14,600 applies)
Taxable income: $55,400

Federal Tax:
· $11,600 × 10% = $1,160
· $35,550 × 12% = $4,266
· $8,250 × 22% = $1,815
Total federal tax: $7,241

FICA: $70,000 × 7.65% = $5,355

Take-home (no state tax): ~$57,404/year ($4,784/month)

Your Effective Tax Rate vs Marginal Rate

People often confuse these two. Your marginal rate is the tax rate on your last pound/dollar of income. Your effective rate is the total tax you pay divided by your total income.

A UK earner on £80,000 is a 40% higher-rate taxpayer (marginal rate), but their effective income tax rate is closer to 23% — because only the portion above £50,270 is taxed at 40%.
