Hi Ruchi,
Please refer the Section 44AD.
in the case of an eligible assessee engaged in an eligible business, a sum equal to eight per cent of the total turnover or gross receipts of the assessee in the previous year on account of such business or, as the case may be, a sum higher than the aforesaid sum claimed to have been earned by the eligible assessee, shall be deemed to be the profits and gains of such business chargeable to tax under the head "Profits and gains of business or profession"
Also, please refer clause 4 of section 44AD
(4) The provisions of Chapter XVII-C shall not apply to an eligible assessee in so far as they relate to the eligible business.
Chapter XVII - Collection & recovery of tax
Section 190 - Deduction at source and advance payment.
Hence, in view of the above, you are not liable for advance tax.
Thanks,
Shobhit
