TDS on salary
I am a beginner and I want few information related to calculation of TDS on salary. The requirement is
slab - Rs 250000 to RS 500000 = Rate is 10%
slab - Rs 500000 to Rs 1000000 = Rate is 20%
slab - Rs 1000000 to Rs 3000000 = Rs is 30%
I know the tds calculation process however, especially in salary part I dont know the process to map this rate for different rates.
Can someone help me, where should i map this rate to get the tds calculation for three different rates.
