Calculate taxes withheld from salary and net income after deductions.
Payroll tax includes income tax, National Insurance, and pension contributions. Employers withhold taxes from salary based on tax codes and employment status. Understanding tax deductions helps with budgeting. UK tax bands vary by income level: basic rate 20%, higher 40%, additional 45%. Tax allowances (£12,570 for 2024-25) reduce taxable income. National Insurance contributions add 8-10% for employees. Pension contributions (3-8%) reduce taxable income while building retirement savings. Regular tax planning optimizes deductions and ensures appropriate withholding.
Tax-free allowances and relief opportunities reduce tax liability. Personal savings allowance enables tax-free interest (basic rate £1,000, higher £500). Dividend allowance exempts first £500 dividends. Gift Aid boosts charity contributions. Trading allowance (£1,000) benefits self-employed. ISA accounts provide tax-free growth. Pension contributions receive tax relief and reduce current tax liability. Understanding and claiming all available reliefs significantly reduces tax burden.
Example 1: £50,000 salary at 20% tax: tax £10,000, net £40,000. Example 2: £100,000 at mixed rates: approximately £25,000+ tax, £75,000 net. Example 3: £30,000 at 20%: tax £3,500, net £26,500 (below higher rate threshold).
