For complex tax situations with filing: ClearTax — when you have capital gains, multiple income sources, and want to file directly from the same platform.Which tax regime is better for most people in 2026?
The new regime is often better if your deductions under Section 80C, 80D, HRA, and other sections total less than about 3.75 lakhs. If your deductions exceed this threshold, the old regime may save more. Use a calculator to check your specific situation — generalizations don't work well here.
Do tax calculators account for the standard deduction?
Most updated calculators include the standard deduction of Rs 75,000 (new regime, FY 2025-26). Always verify the calculator is updated for the current financial year — using last year's slabs will give wrong results.
Can I trust online tax calculators for filing?
Use them for planning and estimation. For actual filing, verify your numbers against the Income Tax Department's utility. Small differences can arise from rounding rules or surcharge thresholds.
