Old regime vs new regime: which is better?
There is no universal answer. In many cases:
- New regime works better when deductions are low.
- Old regime can be better when you claim meaningful deductions (80C, 80D, home loan interest, etc.).
This is exactly why comparison is essential before filing your return or choosing your payroll declaration at the start of the financial year.
Practical tips to reduce tax legally
If you may choose old regime
- Maximize section 80C where relevant.
- Use health insurance deductions under section 80D.
- Track home loan interest eligibility correctly.
- Keep proof and documentation ready for filing.
If new regime looks better
- Prefer a simpler filing process with fewer deduction calculations.
- Review salary structure and employer declarations.
- Check if employer NPS contributions are available where eligible.
