How TDS on Salary works
The employer estimates your annual taxable salary, applies your chosen tax regime and the slabs, and spreads the tax evenly across the year as monthly TDS. Your investment declarations and the standard deduction reduce it. At year end the total is reported in Form 16.
Why TDS on Salary matters
TDS is why your in-hand salary is lower than the gross, and getting your declarations in on time prevents over-deduction and a wait for a refund.
How to keep your TDS from being too high
Because the employer spreads your estimated annual tax evenly across twelve months, the timing of your declarations matters. If you tell the employer early about your rent, home-loan interest and 80C investments under the old regime, or confirm you are within the new-regime rebate, they deduct less each month and your in-hand pay is higher. Leave it late and the employer over-deducts in the early months, then adjusts near year end, so you effectively give the government an interest-free loan and wait for a refund. Checking that the TDS in your payslip matches your Form 26AS or annual information statement each quarter is the simplest way to catch an error before you file.
