As already stated above, the ITR filing exemption limits are different for each type of taxpayer. This exemption limit is further, different for taxpayers choosing between the old tax regime and the new tax regime. On one hand, under the old tax regime, for Individuals, the ITR exemption limit varies as per the exemption limit. On the other hand, under the new tax regime, the ITR exemption is the same for all age groups. Further, under the old tax regime, the income tax slabs are high but the assessee can claim all the exemptions, allowances as well as deductions. But, under the new tax regime, while the Income Tax Slabs are low, the assessee cannot claim all the exemptions, deductions as well as allowances. Accordingly, the ITR filing exemption limits are also different for each taxpayer.
