How Tax Calculation Works
Income tax is calculated on your total taxable income after deducting eligible exemptions and deductions from your gross income. The tax is applied progressively — you pay a lower rate on initial income slabs and higher rates only on income that exceeds each threshold. This means moving into a "higher tax bracket" does not mean your entire income is taxed at the higher rate. Understanding marginal vs effective tax rate is crucial: your marginal rate applies only to the last rupee earned, while your effective rate is the average across all slabs.
Tax-Saving Strategies
Under the old regime, maximize deductions: Section 80C allows up to Rs 1.5 lakh through PPF, ELSS, EPF, and life insurance. Section 80D covers health insurance premiums up to Rs 25,000 (Rs 50,000 for senior citizens). Section 80CCD(1B) offers an additional Rs 50,000 deduction for NPS contributions. Home loan interest up to Rs 2 lakh is deductible under Section 24. Under the new regime, the Rs 75,000 standard deduction and lower slab rates may save you more if your total deductions are below Rs 3.75 lakh. Calculate under both regimes before choosing.

How much National Insurance do I pay on £30000?
On an annual salary of £30000 you pay National Insurance on earnings above the primary threshold of £12570. That means NI on £17430 at 8% which equals approximately £1394 per year or £116 per month. Your employer also pays 13.8% on your earnings above £9100 but that does not come out of your pay packet.
Do I pay NI after State Pension age?
No you stop paying National Insurance when you reach State Pension age currently 66 rising to 67 by 2028. Even if you continue working after State Pension age you are exempt from employee NI contributions. However your employer still pays their share of employer NI on your earnings. This makes hiring older workers slightly more expensive for employers.
Can I fill gaps in my NI record?
Yes you can make voluntary Class 3 NI contributions to fill gaps in your record at £17.45 per week. This can be worth doing if you are short of the 35 qualifying years needed for the full State Pension of £221.20 per week. Each qualifying year adds about £6.32 per week to your State Pension making voluntary contributions one of the best returns on investment available.
What are the UK income tax bands for 2025-26?
Personal Allowance: £0-£12,570 (0%). Basic rate: £12,571-£50,270 (20%). Higher rate: £50,271-£125,140 (40%). Additional rate: over £125,140 (45%). The personal allowance reduces by £1 for every £2 earned over £100,000, creating an effective 60% rate between £100,000-£125,140.
What is the £100,000 tax trap?
When your income exceeds £100,000, you lose £1 of personal allowance for every £2 over. This creates a hidden 60% effective tax rate between £100,000-£125,140. Pension contributions are the most effective way to bring your income below this threshold and reclaim the allowance.
