@KAUSHI K STCG mein sec 87A ke according rebate milti hai, lekin sirf old tax regime mein. (Agar total income aur gain Rs 5L tak hain). New tax regime mein ye pehle mila karti thi, ab nahin milegi.
Ek baat aur, basic exemption Rs 2.5L in old regime (Rs 3L in new regime) abhi bhi le sakte hain STCG par bhi.
Advance tax is to be paid 15% by June 15th, 45% by Sept 15th, 30% by Dec 15th, and remaining by March 15th. Agar total tax 10,000 se kamm ho, advance tax nahin dena padta.
