How to calculate tds amount on salary for senior citizen

According to the new tax regime rates to be calculated 

Likely no TDS at Rs 6 lakh (new regime):

• FY 2024-25 (new regime): salary Rs 6,00,000 minus standard deduction Rs 75,000 = Rs 5,25,000. Tax: 3–5.25 lakh at 5% = Rs 11,250. Rebate under 87A (income up to Rs 7 lakh) brings tax to nil. So no TDS.

• FY 2025-26: rebate up to Rs 12 lakh total income. Nil.

• The new regime has no separate senior-citizen slab (the basic exemption is the same Rs 3 lakh / Rs 4 lakh). Under the old regime, seniors get Rs 3 lakh basic exemption.

• The employer computes TDS on estimated annual income (Sec 192) under the regime opted for, considering other income declared by the employee.
