When you earn income from business or profession, the Income Tax law expects you to keep proper records. These records are called books of account. Section 62 of the Income Tax Act, 2025 and Rule 46 together explain:
- Who must maintain books
- What books should be maintained
- Where and how to maintain them
- How long to keep them
If you understand this properly, you can avoid penalties and handle your taxes with confidence.
What Does “Maintenance of Books of Account” Actually Mean?
Imagine you run a small shop or work as a freelancer. Every day, money comes in and goes out. Now, if someone asks: “How much did you actually earn this year?”
You should be able to show it clearly.
That’s exactly what this rule is about. You need to keep proper records—like income, expenses, bills, and other documents—so that the Income Tax Officer can calculate your total income correctly.
Basic Requirement under Section 62
The tax law clearly says that certain persons must maintain books of account and documents so that the Assessing Officer can compute their total income. This requirement applies to:
- Persons in specified professions
- Persons doing business
- Persons in other professions (if certain conditions are met)
The main idea is simple: You should be able to clearly show your income and expenses whenever required.
Conditions for Business and Non-Specified Professions
If you are not in a specified profession, then books are required only when certain limits are crossed. You must maintain books if:
- Income exceeds ₹1,20,000
- Turnover or gross receipts exceed ₹10,00,000 in any of the last 3 years
- For new business, income or turnover is likely to cross these above limits
- You declare income lower than presumptive income (important point)
Example
Rahul runs a small trading business. Last year his sales were ₹12 lakh. Even if this year is slow, he still needs to maintain books because he crossed the limit earlier.
Neha starts a boutique. She expects sales of ₹15 lakh in the first year. Even though it’s her first year, she should maintain books.
Higher Limits for Individuals and HUF
For individuals and HUF, the limits are relaxed:
- Income exceeds ₹2,50,000
- Sales/turnover exceeds ₹25,00,000
This means small taxpayers are not forced to maintain detailed records unless their scale increases.
Important Case: Presumptive Income Declared Lower
This is a very important practical situation. If you are covered under presumptive taxation (like Sections 58(2) or 61(2)) and you declare income lower than deemed profits. Then:
- You must maintain books of account
- Even if your income or turnover is small
This rule prevents misuse of presumptive schemes.
If you claim “my profit is less than what the government assumes,” you must prove it with proper records.
What is a Specified Profession?
Specified professions are those where professional expertise is used. These include:
- Legal (lawyers)
- Medical (doctors)
- Engineering
- Architecture
- Accountancy (CAs)
- Technical consultancy
- Interior decoration
- Information technology
- Company secretary
- Any other notified profession (if the government notifies any new profession, it will be added)
If you are in these fields, the law expects more structured record-keeping.
Power of the Board (CBDT)
Section 62 also gives authority to the Board to prescribe:
- Which books must be maintained
- What details should be included
- How and where records should be kept
- How long they should be preserved
This is why Rule 46 exists — it gives practical rules.
Rule 46 – What Books Must Be Maintained
Rule 46 explains the actual books required, especially for professionals. For specified professionals, the following books must be maintained:
- Cash book
- Journal (if using mercantile system)
- Ledger
- Copies of bills issued (above ₹250)
- Original expense bills (above ₹250)
- Signed Payment vouchers for small expenses, where the expenditure incurred does not exceed ₹250
These records help track every transaction clearly.
Exception for Small Professionals
There is relief for small professionals. You are not required to maintain detailed books if:
- Gross receipts do not exceed ₹1,50,000 in any of the last 3 years
- For new profession, receipts are not likely to exceed this limit
This helps beginners and small practitioners.
Additional Requirements for Medical Professionals
Doctors have extra responsibilities because of the nature of their work. In addition to the books of account and other documents specified above they must maintain:
- Daily case register (Form 25)
- Inventory of medicines and consumables (beginning and end of year)
This ensures proper tracking of professional activity.
Some terms used in the rule have specific meanings.
- Cash book: Daily record of cash received and paid, with balance
- Authorised representative: Person representing others before tax or legal authorities for a fee
- Film artist: Includes actors, directors, singers, writers, etc.
These definitions clarify who falls under the rules.
Where Should Books Be Maintained?
Books should be kept at:
- Main place of business or profession
- Principal place if multiple locations
- Or separately at each place if separate books are maintained
For electronic records:
- Must be accessible in India
- Backup must be stored in India
- Must be updated regularly (daily basis)
This ensures control and accessibility for tax authorities.
How Long Should Books Be Kept?
Books must be preserved for 7 years from the end of the tax year
But if your case is reopened you must keep books until the reassessment is completed
This is very important during scrutiny cases.
What Happens if You Do Not Maintain Books?
If you fail to maintain proper books:
- Income may be estimated by the department
- You may face penalties
- You may lose the benefit of claiming expenses
In simple terms, not maintaining books can increase your tax burden.
Example
Suppose you are a freelancer earning ₹12 lakh per year.
- Since your income exceeds limits, books are mandatory
- You must keep records of:
- Payments received
- Expenses like rent, internet, etc.
If you don’t maintain records, you may not be able to justify your expenses.
Conclusion
Maintenance of books of account under Section 62 and Rule 46 is not just a legal requirement—it is a practical necessity. It helps you stay organised, calculate your income correctly, and avoid problems with the tax department.
Even if your income is small today, building the habit of maintaining proper records will make your financial life much smoother as your income grows.
