Income Tax notices have become far more common in recent years—not necessarily because businesses are indulging in tax evasion, but because the Income Tax Department now relies heavily on data analytics, system-driven comparisons, and automated risk profiling.
Every financial activity—bank transactions, GST filings, TDS returns, investments, and high-value purchases—creates a digital footprint. This information flows into platforms such as AIS (Annual Information Statement), TIS (Taxpayer Information Summary), Form 26AS, GSTN, and banking systems, all of which are automatically cross-verified with your books of accounts and Income Tax Return.
What many taxpayers fail to realise is that even small mismatches, incomplete disclosures, or weak documentation can trigger an Income Tax notice. In most cases, notices arise not from intentional wrongdoing, but from poor bookkeeping practices, delayed reconciliations, or lack of professional review.
For businesses and professionals, an Income Tax notice is not just about additional tax—it leads to stress, time-consuming follow-ups, professional costs, and disruption of regular operations. Issues that could have been resolved early often escalate into interest, penalties, and prolonged assessment proceedings.
This blog highlights the key red flags in books of accounts that commonly invite Income Tax notices and explains how businesses can identify and correct these risks early.
1. Mismatch Between Books of Accounts, ITR, AIS & TIS
One of the most common reasons for Income Tax notices today is data mismatch.
Common issues include:
• Turnover as per books not matching GST returns
• Interest income appearing in AIS but not recorded in books
• TDS reflected in Form 26AS but corresponding income not offered to tax
• High-value transactions reported by banks but missing in the ITR
Why it invites notices:
The tax system automatically flags inconsistencies between declared income and third-party data.
How to avoid it:
Books of accounts should be reconciled with AIS, TIS, Form 26AS, and GST returns before filing the return.
2. Abnormal Fluctuations in Turnover or Profit Margins
Sudden increases or drops in turnover or profits without proper explanation often attract scrutiny.
Red flags include:
• Sharp fall in profit compared to previous years
• Significant increase in expenses without business justification
• High turnover growth with consistently low or negative profits
Why it invites notices:
Such trends may indicate income suppression, expense inflation, or aggressive tax planning.
How to avoid it:
Maintain documentation explaining year-on-year variations.
3. Excessive Cash Transactions
Despite increased digitalisation, cash usage remains a major risk area.
Risky practices include:
• Large cash receipts or payments
• Cash expenses beyond permissible limits
• Cash loans or repayments violating Sections 269SS and 269T
Why it invites notices:
Cash transactions are closely monitored due to their potential link to unaccounted income.
How to avoid it:
Limit cash transactions and ensure strict compliance with statutory limits.
4. Unsecured Loans Without Proper Documentation
Unsecured loans are one of the most scrutinised items during assessment.
Common issues include missing confirmations, lack of PAN or ITR of lenders, and absence of creditworthiness.
Why it invites notices:
Such loans may be treated as unexplained cash credits under Section 68.
How to avoid it:
Maintain documentation establishing identity, creditworthiness, and genuineness of lenders.
5. High Expenses Without Supporting Bills or Vouchers
Claiming expenses without adequate support is a frequent issue.
Red flags include:
• Large miscellaneous expenses
• Personal expenses routed through business accounts
• Heavy reliance on self-made vouchers
Why it invites notices:
Unsupported expenses are often disallowed during scrutiny.
How to avoid it:
Maintain proper bills, invoices, and clear segregation of personal and business expenses.
6. Mismatch Between GST Returns and Books of Accounts
GST data is extensively used for Income Tax verification.
Common mismatches include differences between GSTR-3B turnover and Profit & Loss Account.
Why it invites notices:
GST–Income Tax cross-verification is largely automated.
How to avoid it:
Conduct periodic GST-to-books reconciliations.
7. Incorrect Depreciation or Capitalisation of Assets
Errors in fixed asset accounting directly affect taxable income.
Red flags include claiming depreciation on non-business assets or applying incorrect rates.
How to avoid it:
Maintain a fixed asset register and apply Income Tax depreciation rates correctly.
8. Related Party Transactions Without Proper Disclosure
Transactions with directors, partners, or relatives require transparency.
Risk areas include excessive remuneration, interest-free loans, or inflated purchases.
Why it invites notices:
Such transactions are examined for profit shifting or tax avoidance.
How to avoid it:
Ensure arm’s length pricing and proper disclosures.
9. Non-Disclosure of Exempt or Other Income
Even exempt income must be disclosed.
Examples include dividend income, agricultural income, and foreign income.
Why it invites notices:
Non-disclosure may be treated as concealment.
How to avoid it:
Ensure complete and accurate disclosure.
10. Poorly Maintained or Incomplete Books of Accounts
Poor accounting discipline itself is a red flag.
Warning signs include backdated entries, absence of reconciliations, and incomplete records.
Why it invites notices:
Poor books weaken defence during assessments.
How to avoid it:
Maintain real-time, accurate, and reconciled books.
