Dear Concern, I'm a contractor for interior work like onsite manufacturer of wardrobe,modular kitchen ,paint and other interior works. But not a qualified "Interior Decorator" I'm so confused to file ITR for AY 2018-19.Will it count as profession or business for filling ITR 4 ?? As income under profession is calculated @ 50% of receipt and in Business it is @ 8%. Kindly advice
