W.M.W #41: Don't Overpay Taxes: Meet Form 10-IEA

Reading time: 5 minutes - March 28, 2026

Hey Reader

Open your calendar. Look at July 31 - Something that might ring a bell!!
It's the ITR Filing date. But there's another critical deadline on the same day that most people have never heard of.

Form 10-IEA.

If you have business or professional income and you miss this form, here's what happens:
- You file your ITR post July. Everything looks fine. You get your assessment order in September. Your tax: ₹4.2 lakhs.
- Then your CA calls: "If you'd filed Form 10-IEA, your tax would've been ₹3.5 lakhs. You overpaid ₹70,000."

You: "What's Form 10-IEA? Can I file it now?"
​CA: "No. Deadline was July 31. You're locked in for the year."

This exact scenario has played out thousands of times since the government made new tax regime the default from FY 2023-24 (April 2023).

The problem: For business/professional income earners, opting for old regime (with deductions like 80C, HRA, home loan interest) requires filing a separate form before ITR deadline.

The bigger problem: Nobody tells you this. Not the IT portal. Not the filing software. Not even most CAs until it's too late. Today, I'm showing you exactly what Form 10-IEA is, who needs it, and how to file it in under 10 minutes - before July 31.

What is Form 10-IEA?

In simple terms: It's the form that lets you choose old tax regime if you have business/professional income.
​Why it exists: From AY 2024-25 onwards, new regime is default. The government assumes you want new regime unless you say otherwise.
​- For salaried people: You can opt out while filing ITR. No separate form needed.
​- For business/professional income: You must file Form 10-IEA separately before ITR deadline to opt for old regime.

If you don't file Form 10-IEA: You're locked into new regime. No 80C deduction. No HRA. No home loan interest benefit. Nothing.

Who Must File Form 10-IEA?

You need this form if:
✅ You have income from business or profession
✅ You want to opt for old tax regime (to claim deductions)
✅ You're an Individual, HUF, AOP, BOI, or AJP

You don't need this form if:
❌ You're purely salaried (no business income) → Just opt out while filing ITR
❌ You're happy with new regime → Do nothing, it's default

What counts as business/professional income?

Not sure if you have "business/professional income"?

You do if any of these apply:

• You freelance, consult, or invoice anyone for services
• You run any business (even a side one)
• You're a doctor, lawyer, CA, architect, or any licensed professional
• You file under presumptive income (44AD/44ADA)
• You earn salary and any of the above

The Critical Deadline (This is Time-Sensitive!)

Form 10-IEA must be filed before your ITR due date.

For most people:

• ITR due date: July 31
• Form 10-IEA deadline: July 31 (same)

Miss this deadline = stuck in new regime for the entire year.

How to File Form 10-IEA (Step-by-Step)

Time needed: 10 minutes

Step 1: Login to Income Tax e-filing portal (https://eportal.incometax.gov.in)

Step 2: Go to e-File > Income Tax Forms > File Income Tax Forms

Step 3: Search for "Form 10-IEA" or select it from the list

Step 4: Select Assessment Year (e.g., AY 2026-27 for FY 2025-26)

Step 5: Confirm you have business/professional income → Click Yes. Then Select your ITR due date (usually July 31)

Step 7: Confirm selection of Regime

Step 8: Fill basic information (auto-prefilled: Name, PAN, Status)

Step 9: Fill additional information (if you're in IFSC unit, otherwise leave blank)

Step 10: Declaration and verification

Step 11: E-verify using Aadhaar OTP / Net Banking / EVC

Step 12: Submit. Note the Transaction ID for reference.

Done. You're now in old regime.

What Happens If You Miss the Deadline?

Scenario: You realize on August 5 that you should've filed Form 10-IEA by July 31.
Can you file late? No. Deadline is hard.
​Can you revise? No. Form 10-IEA can't be revised or filed late.
​What happens?

• You're in new regime for the entire year
• No 80C, no HRA, no home loan deduction
• You pay higher tax
• You can opt out next year

Common Mistakes People Make

#Mistake 1: "I'll decide while filing ITR" Wrong. If you have business income, Form 10-IEA must be filed separately before ITR deadline.

#Mistake 2: "I filed last year's Form 10-IEA, so I'm covered" Wrong. Form 10-IEA is year-specific. File fresh every year before ITR deadline.

#Mistake 3: "I can file it anytime before March 31" Wrong. Deadline is your ITR due date (usually July 31), not financial year end.

#Mistake 4: "I'll switch regimes mid-year" Wrong. Once you file ITR, you're locked for that year. Can't change.

👉 Action Steps (Do This Before July 31, 2025)

Step 1: Check if you need Form 10-IEA
​- Do you have business/professional income? → Yes = File Form 10-IEA
- Only salary income? → No separate form needed

Step 2: Calculate which regime saves you more
​- Use tax calculator on IT portal
- Compare old vs new regime
- Factor in all deductions (80C, HRA, home loan)

Step 3: If old regime is better, file Form 10-IEA NOW
​- Don't wait till July 31
- File by mid-July to avoid last-minute rush
- Keep Transaction ID safe

Step 4: Set annual reminder
​- Every June 15: "File Form 10-IEA"
- Make it non-negotiable like ITR filing

If this saved you from a costly mistake, forward it to one friend with business/consulting/freelance income. They likely don't know about Form 10-IEA either.
