On review, here is the correct legal position:
1. Sec 44ADA fixes 50% of gross receipts as the MINIMUM presumptive income a sum equal to fifty per cent or a sum higher than the aforesaid sum claimed to have been earned by the assessee. It is a floor not a flat rate.
2. Your actual expenses (~₹8L) against receipts of ₹70L work out to actual profit of ~₹62L. The correct income to declare is this actual figure, not the flat ₹35L (50%)
3.Practical benefit: declaring the true ~₹62L income means your tax filing and your investments (FD/MF) will match – no mismatch for AIS/SFT to flag, no need to later justify the gap.
4. Under Section 44ADA(4), if a taxpayer claims that their actual profits are lower than 50% (for instance, claiming actual expenses of ₹ 36 Lakhs to show taxable profit of only ₹34Lakhs), the law mandates two strict requirements:
- You must maintain detailed books of accounts and vouchers under Section 44AA.
- You must get your accounts audited by a Chartered Accountant under Section 44AB and prove every expense claimed.
5. if you declare only 50% (~₹35L) as income but your Annual Information Statement (AIS)/Statement of Financial Transactions (SFT) shows ~₹62L moving into FDs and mutual funds in the same year, this mismatch is a strong trigger for the Department's automated risk-assessment (CASS) flagging, and you should expect a query or notice asking you to explain the source of investments exceeding your declared income.
This is a real and likely outcome, not a remote possibility — the gap here is large enough (~₹27L over declared income) to draw attention even though the source is fully genuine. Declaring income closer to the actual ~₹62L profit removes this trigger altogether, since declared income and investments will then be consistent.
My recommendation:- You should declare income of approximately ₹62 lakh (actual profit, subject to final expense reconciliation) under Section 44ADA for this year, rather than the flat 50% (₹35 lakh). This is legally sound.
The additional tax outgo now is the cost of a clean, notice-proof filing declaring 35L to save tax today only to face a scrutiny query and possible litigation later, is not a trade worth making given the size of the gap.
