Dear Swathy,
The only component that makes a difference tax-wise is the conveyance allowance. The rest of the components are of little materiality, except if you want to use them to favor a particular segment or type of employees or give some additional amount to those who need to spend in line with work.
Earlier, the breakup was important to reduce PF incidence, which is now mostly immaterial after the February 2019 Supreme Court case, which makes almost all allowances other than HRA a part of Basic. For ESIC, the payment is on the gross, so again, no impact.
Once the Code on Wages is implemented, you will need to provide at least 50% of wages as basic. But till then, you can manipulate things by giving more on HRA. But in the end, the impact is marginal.
Also note, Minimum Wages are defined as Basic + DA. In working components, do not end up being below the minimum wages.
