How it works
Enter the TDS amount, the dates when TDS was due, deducted and paid, and any days the return was filed late.
Tips
- Figures use the latest published rates; government scheme rates are revised every quarter.
- Choose between the old and new tax regimes carefully – deductions only count in the old regime.
- Keep proofs of investments and rent for your employer and the tax return.
- Use the official portal of each scheme for exact maturity values.
Common mistakes to avoid
- Assuming scheme interest rates are fixed for the whole term.
- Forgetting tax on interest from fixed and recurring deposits.
- Missing the yearly minimum deposit on PPF or Sukanya Samriddhi accounts.
