Who Must Maintain Books of Accounts?
Under Section 44AA, books are mandatory above ₹1 crore turnover. I see ₹25,000+ penalties for non-compliance in Delhi. But many businesses below the threshold should also maintain books -- for loan applications, investor presentations, and smooth tax filing.
Official Reference: Section 44AA of the Income Tax Act 1961 specifies who must maintain books. Rule 6F lists the specific books required for professionals. Section 44AB mandates tax audit if the prescribed limits are exceeded. Section 271A prescribes penalty for non-maintenance of books.
Mandatory maintenance if:
- Business turnover exceeds ₹1 crore (₹10 crore if 95%+ digital transactions)
- Professional gross receipts exceed ₹50 lakh
- You claim income below presumptive taxation limits (Section 44AD/44ADA)
- You are covered under tax audit (Section 44AB)
- You are a company or LLP -- regardless of turnover
📍 Real Example -- Penalty Case -- Laxmi Nagar Trader
A trader in Laxmi Nagar with ₹1.5 crore turnover did not maintain any books. During assessment, the AO could not verify his income claims. Under Section 271A, penalty of ₹25,000 was levied. Additionally, under Section 44AD, since he did not maintain books and his declared profit was below 8%, his income was assessed at 8% of turnover -- increasing his tax by ₹3.6 lakh.
What Records to Keep
Under Rule 6F, professionals must maintain these specific books:
- Cash book -- daily cash receipts and payments
- Journal -- if mercantile system of accounting (most businesses use this)
- Ledger -- all accounts consolidated
- Copies of bills/receipts issued -- above ₹25
- Original bills for expenses -- above ₹50 (₹25 for some categories)
- Bank statements -- monthly reconciliation
For businesses (non-professionals), the requirements are broader:
- All the above plus
- Quantitative records -- for trading/manufacturing businesses (stock register)
- Fixed asset register -- for depreciation computation
- Salary register -- if you have employees
How to Maintain Books
- Choose accounting method: Mercantile (accrual) is recommended -- most common, required for companies
- Use accounting software: Tally, Zoho Books, or Busy -- automated GST, less errors
- Daily entries: Do not let entries pile up -- 30 minutes daily saves 3 days at year-end
- Monthly reconciliation: Match bank statement with your books every month
- Digital backup: Keep scanned copies of all bills in cloud storage
💡 Pro Tip from Parul: For businesses with turnover ₹1-5 crore, I recommend Tally Prime with GST integration. The software handles invoicing, GST returns, and inventory management. Cost: ₹18,000 one-time. It pays for itself in the first year through reduced CA fees and avoided penalties.
Retention Period
Books of accounts must be retained for a minimum of 7 years from the end of the relevant assessment year. For example, books for FY 2019-20 (AY 2020-21) must be retained until 31st March 2028.
⚠️ Common Mistake: Destroying books before the 7-year period can attract penalty under Section 271A. If the AO initiates proceedings, you must retain books until the case is closed, even if 7 years have passed. Many Delhi businesses discard old books after 3-4 years -- this is illegal.
Penalties for Non-Compliance
| Violation | Penalty |
|---|---|
| Not maintaining books (Section 271A) | ₹25,000 |
| Not getting audit done (Section 271B) | 0.5% of turnover (max ₹1.5 lakh) |
| Furnishing inaccurate information (Section 271A) | ₹25,000-₹1,00,000 |

Frequently Asked Questions
Is maintaining books on computer/software acceptable?
Yes, digital books are fully acceptable. In fact, Rule 6F(2) specifically allows maintenance of books on computer. Ensure you take regular backups and can produce printouts when required by the AO.
What if my turnover is below ₹1 crore?
Maintenance is not mandatory, but I strongly recommend it. Without books, you cannot claim actual expenses -- and under presumptive taxation (44AD), your income is deemed at 8% of turnover regardless of actual expenses. This often results in higher tax than necessary.
Do freelancers need to maintain books?
Only if gross receipts exceed ₹50 lakh or you claim profit below 50% under Section 44ADA. However, even below this threshold, maintaining basic records helps you optimize tax, track income, and avoid disputes with clients over payments.
