How do taxes work on my salary and how can I legally reduce them?

Income tax is calculated in slabs, which is the part most people misunderstand: moving into a higher bracket doesn't tax your entire income at that rate — only the portion above the threshold. A raise never leaves you worse off. **How the slab system works**: if the first tranche of income is taxed at 5%, the next at 20% and the rest at 30%, then someone just above the 30% threshold pays 30% only on the amount above it. Your *effective* rate — total tax divided by total income — is always lower than your top slab rate. **The main legal ways to reduce it** (specifics vary by country, so verify against your own rules): 1. **Retirement contributions.** Usually the largest available deduction, and it's money going to your future self rather than being spent. If your employer matches, take the full match first. 2. **Statutory deductions and allowances** — the standard deduction, and any allowances for housing, transport or specific expenses your system provides. 3. **Health insurance premiums**, often deductible. 4. **Home loan interest and principal**, where applicable. 5. **Education loan interest.** 6. **Charitable donations** to qualifying organisations. 7. **Choosing the right tax regime**, where your country offers alternatives (India, for instance, has old and new regimes with different rates and deduction rules — run both calculations, because which is better depends entirely on your deductions). **Structural things worth knowing:** - **Salary structuring.** Some employers allow you to allocate part of your package to components with favourable tax treatment. Ask HR what's available — many people never do. - **Long-term capital gains** are usually taxed more favourably than short-term. Holding investments longer is often a tax decision as well as an investment one. - **Tax-advantaged accounts** for retirement or specific goals — use the full allowance where you have one, since unused allowance usually doesn't carry forward. **The important caution**: don't let tax saving drive bad financial decisions. Buying a poor insurance-cum-investment product to save tax is a common and expensive mistake — you save a fraction in tax and lose more in fees and returns. Buy things that make sense on their own merits; take the tax benefit as a bonus. And if your situation is at all complex, one session with a qualified tax professional usually pays for itself.
