Frequently Asked Questions
What is CMP-08?

CMP-08 is a quarterly challan cum return statement filed by businesses under GST composition scheme. It declares self-assessed tax payable for the quarter at flat rates (1%, 2%, or 5% depending on turnover slab).

Is CMP-08 filing mandatory?

Yes. CMP-08 must be filed every quarter even if there are no sales during the period (nil filing).

What is the CMP-08 due date?

CMP-08 is due on the 18th of the month succeeding each quarter: 18th July (Q1), 18th Oct (Q2), 18th Jan (Q3), 18th April (Q4).

What are the flat tax rates under composition scheme?

Rates are: 1% for manufacturing/trading under ₹1Cr turnover, 2% for trading ₹1-1.5Cr, 5% for services/hybrid businesses. Rates are applied on quarterly turnover.

Can composition scheme businesses claim ITC?

No. Composition scheme businesses cannot claim Input Tax Credit (ITC). All GST on purchases is a cost and cannot be credited.

What happens if CMP-08 is filed late?

Late filing incurs interest at the rate applicable. No late fee capped limit currently, so interest accrues on unpaid tax amount until payment.
