Impact of Designation Change on Tax Liability
By changing the designation from Assistant Associate Professor to Consultant, the tax liability will not change. A consultant is someone who is consulted for specific matters. They will not be available in the office or college throughout the day, week, or month. They will not follow office timings, nor will HR policies relating to leaves, taking approval from the HoD for leave, dress code, etc., be applicable to them. I understand that you attend the sessions every day, evaluate students' papers, and remain in the college until the sessions end from Monday to Friday, from the 1st of the month until the last day. Please go through a case on the same subject attached.
Salary Components and Tax Reduction
Inclusion of certain components like HRA, conveyance allowance, etc., as part of the salary may reduce your tax burden. However, these are subject to other conditions, such as if you are residing in an owned house or if your spouse is receiving HRA, then you will not get the benefit of HRA. A reasonable amount can be put as reimbursements, like fuel reimbursement, telephone reimbursements, reimbursement of books and periodicals for upskilling, etc. Normally, allowances will be part of the salary and thus taxable, but reimbursements will be excluded from the salary head. Similarly, you can also contribute to EPF.
