The tax exemption limit for conveyance allowance is set at Rs. 1,600 per month, irrespective of the tax bracket a person falls under. If the individual is given a special allowance, which is fully taxable, then he or she can substitute Rs. 1,600 from it as conveyance allowance and claim tax exemption on it.
For example, if a company is offering a special allowance of Rs. 5,000 per month (100% taxable), Rs. 1,600 out of the total of Rs. 5,000 can be allocated as conveyance allowance and tax exemption can be claimed on it. However, it is advisable to first consult with a tax expert before going ahead with claiming tax exemption on conveyance allowance.
