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.

Is Adelaide affordable compared to other capitals?

Combined with lower stamp duty generous FHOG ($15000 vs $10000 in most states) and lower cost of living Adelaide offers strong affordability. Many interstate buyers are relocating to Adelaide for the combination of lifestyle and property value.
Which tax regime should I choose — old or new?
Choose the new regime if your total deductions are below Rs 3.75 lakh. Choose the old regime if you claim HRA, 80C (Rs 1.5L), 80D, home loan interest, and NPS totaling more than Rs 3.75 lakh. Salaried employees can switch every year.
Is income up to Rs 12 lakh really tax-free?
Under the new regime for FY 2025-26, income up to Rs 12 lakh is effectively tax-free due to Section 87A rebate. After Rs 75,000 standard deduction, taxable income is Rs 11.25 lakh which qualifies for full rebate. However, income even slightly above Rs 12 lakh loses this entire benefit.
How can I save more tax legally?
Under the old regime, maximize 80C (Rs 1.5L via PPF, ELSS, EPF), 80D (Rs 25K-50K for health insurance), 80CCD(1B) (Rs 50K for NPS), HRA exemption, and home loan interest (Rs 2L under Section 24).
