You may utilise the overall 7.5Lakh upper limit slab for the combined deposit of EPF, NPS, Superannuation which can be deducted from your salary. It affects the take home pay but you save in the income tax deduction from your salary itself.
Also, you have partial tax free withdrawal under special circumstances from EPF, NPS after some years, guess it is 5 years or something. You can check this further.
But the best part is your taxable income gets reduced at the company side itself and tax doesn’t get deducted and get deposited with the government for you to file returns and show evidences via this method. Also, the interest is decent enough for time being.
However, you can also explore the option of a taking a small home loan as well if you really want to get that benefit as well. You can reduce 2lakhs from the Home loan option as well.
If your company provides health insurance for yourself and your family and also your parents, just add all the top up that you can possibly do if you don’t have a separate insurance for the same. That also reduces the taxable income.
