If you are running a small business or doing freelance work, you may have heard about Income tax return form ITR-4 (SUGAM). It is meant to make tax filing simpler under presumptive taxation. But many people get confused about who can actually use ITR-4 and who cannot.
Rule 164 of the Income tax rule 2026 helps you understand this clearly. It explains eligibility conditions, restrictions, and when you must use ITR-3 instead. Let’s break this down in a simple, practical way.
What does Rule 164 say about ITR-4 (SUGAM)?
Rule 164 basically tells you that ITR-4 is meant for small taxpayers using presumptive taxation schemes. If you are eligible, you can declare income at a fixed percentage and avoid maintaining detailed books.
To qualify, you must be:
- An individual
- A Hindu Undivided Family (HUF)
- Or a firm (but not an LLP)
- And you must be a resident in India
Also, your business income should be calculated under presumptive taxation sections. In addition, you can also have small capital gains, but only under a specific condition:
- Only long-term capital gains
- And it should not exceed ₹1,25,000 for the year
This means ITR-4 is designed for simple income situations, not complex ones.
Who is not allowed to file income tax return form ITR-4?
Now this is the most important part. Many people assume they can use the income tax return form “ITR-4”, but a single condition can make them ineligible.
Let’s go step by step.
You cannot use ITR-4 if:
- You own assets outside India
- You have a bank account abroad with signing authority
- You earn income from outside India
These cases require detailed reporting, so a simple income tax return form like ITR-4 is not allowed.
If your financial situation is complex
ITR-4 is not allowed if:
- Your total income exceeds ₹50 lakh
- You own more than 2 house properties
- You have losses to carry forward (like business loss or capital loss)
These situations need proper computation and tracking, which ITR-4 does not support.
If you are involved with companies
You cannot use ITR-4 if:
- You are a director in any company
- You have invested in unlisted shares
This is because such cases require additional disclosures.
If you claim certain deductions or reliefs
ITR-4 is also not allowed if:
- You claim special deductions under certain sections
- You are claiming tax relief under specific provisions
These involve deeper tax calculations.
If you have special types of income
You cannot use ITR-4 if:
- Agricultural income exceeds ₹5,000
- You have income taxed under special rules (like certain salary components or special tax rates)
These cases again need detailed reporting. If your income is partly taxed in another person’s hands (clubbing provisions), then ITR-4 cannot be used.
Why these restrictions matter
All these conditions have one simple reason, ITR-4 is meant for simplicity.
If your income becomes even slightly complex, the government requires you to shift to a more detailed form.
When should you use ITR-3 instead?
If you do not qualify for ITR-4 but still have business or professional income, then you must use the Income tax return form ITR-3.
ITR-3 applies when:
- You have business income but not under presumptive scheme
- Or you are disqualified from ITR-4 due to any of the above reasons
ITR-3 is more detailed. It requires:
- Proper income calculation
- Books of accounts (if applicable)
- Detailed disclosures
So, think of it like this:
- ITR-4 → Simple cases
- ITR-3 → Detailed and complex cases
Do you need to attach documents with your return?
Rule 164 of the income tax rule, 2026, clearly states something very useful.
You do not need to attach documents like:
- Tax computation sheet
- TDS certificates
- Proof of advance tax
- Audit reports
- Account statements
This is because income tax filing in India works on a self-declaration system. However, this does not mean you can ignore records.
You should always keep these documents safely in case the department asks for verification later.
How should the return be filed?
The rule also mentions that returns must be filed in the prescribed manner, usually:
- Online (e-filing portal)
- Using digital verification or OTP-based verification
The exact method depends on your category, but today almost all filings are done digitally.
Conclusion
Rule 164 is all about choosing the correct ITR form based on your income situation. If your income is simple and falls under presumptive taxation, income tax return form “ITR-4” makes life easy.
But the moment your financial situation becomes slightly complex—like foreign income, higher income, losses, or company involvement—you must move to ITR-3.
Understanding this rule properly helps you avoid mistakes, notices, and unnecessary stress during tax filing.
