ITC OF CAPITAL GOODS

You have to claim full ITC of capital goods like any other Goods in 3b return

Section 16 of CGST Act, 2017 doesn't make distinction between Capital goods and Other goods for allowing ITC. You can claim complete ITC at once but no depreciation on such ITC on Capital Goods should have been claimed under Income Tax act. If depreciation is claimed on such tax component ITC will not be allowed under section 16(3).

Capital Goods ki ITC, Purchase ke time pe ek saath hi claim karni hoti hai.
Same like claim of ITC on any others Goods.
