ITR Filing For Founders & Startups: A Step-By-Step Guide in 2026

In this blog, we'll go through how to file ITR online, explain which ITR form fits for founders & startups, clear the confusion around the ITR filing last date, and discuss practical fee expectations. If your startup is also building an e-commerce brand and is ready to scale online, Gonukkad ecommerce seller services can be your growth partner for seller account setup, listing, optimization, and ad campaigns.

What Is ITR Filing

ITR Filing means submitting your income details to the Income Tax Department every year.

Founders usually think, the startup didn’t earn anything, so why file?

But in reality, the entity must file, and founders may still need to file if they have personal income from salary, freelancing, capital gains, or other sources.

Also, ITR Filing is not just a legal checkbox because investors, banks, and even some large vendors check ITR history during due diligence and credibility checks. So if you’re building a serious business, clean filings and clean records make expansion smoother.

ITR Filing For Founders & Startups: Who Files What

Here’s the simplest way to understand ITR Filing for Founders & Startups: founders file as individuals, and startups file as entities.

Founder Common ITR Forms

• ITR-3: Common for individuals and HUFs that have income from business or profession.


• ITR-4: For presumptive income cases under Sections 44AD/44ADA/44AE only for eligible cases, and not for LLPs.


• ITR-1: It's mainly for regular salaried people who meet specific criteria; it's not for those with business or professional income, and many founders can't take advantage of it.


• ITR-6: For companies, including private limited startups, except those claiming exemption under Section 11.


• ITR-5: Commonly used for LLPs and partnership firms.

Choosing the correct form for ITR filing is important, as using the wrong one can lead to notices or rejection issues down the line.

What Is The Last Date For ITR Filing

The ITR filing last date depends on whether your case is a non-audit, audit, or transfer pricing audit.




For AY 2025–26, CBDT extensions were issued for audit cases, including dates like audit report by 10 Nov 2025 and ITR by 10 Dec 2025 for non-TP audit cases, and TP cases by 30 Nov 2025.




So, for ITR Filing, the practical advice is: first confirm whether your startup requires an audit under tax rules, then follow the due dates for that category instead of blindly following generic posts.

Step-By-Step Process For ITR Filing Online

Step 1: Keep Basics Ready

• PAN, Aadhaar, and mobile links for OTP flows.


• Bank account details for refund and validation.


• ​TDS details, income proofs, and basic books summary for founders and the entity.



Step 2: Log In & Start Return

On the Income Tax portal, after login:



• Go to e-File and click on Income Tax Returns.


• File Income Tax Return to begin ITR Filing.


• Select the Assessment Year, choose online mode, and proceed.



Step 3: Select Start New Filing or Resume

If there’s a draft saved, continue from there, and if not, start fresh. It is important because many people get halfway through their form and then feel stressed later on.

Step 4: Choose Status & Correct ITR Form

Choose your status and select the ITR form that matches your case. The single step decides whether your ITR Filing is smooth or becomes a problem later.

Step 5: Review Prefilled Data, then Edit Carefully

Just because some information is filled in for you doesn’t mean it’s all correct.



• Check things like your salary, interest, TDS, and any other auto-filled details to make sure they’re right and fix anything wrong.


• Don't forget to confirm each section, as a lot of people overlook this step and their submission ends up failing.

Step 6: Tax Regime Choice

For AY 2025–26, the portal notes that the New Tax Regime is the default for individuals, and opting out of the old regime needs explicit selection in the return where applicable.




Many founders lose deductions simply because they didn’t notice it while doing their ITR Filing.

Step 7: Pay Tax

If tax is payable, the portal flow gives “Pay Now/Pay Later” options, and the guide recommends Pay Now to reduce default/interest risk. After payment, come back and complete the return submission.

Step 8: Validate, submit, and e-verify (very important)

After validation, submit the return and complete verification.




E-verification is the easiest method, and the portal also mentions that you must verify within the timeline. Otherwise, the return may be treated as invalid, and late consequences can apply.

What Are The ITR Filing Fees For Individuals & Startups

Government late fee and professional filing fee are different things, and people mix them up during ITR Filing. The filing portal itself doesn’t charge a filing fee. But late filing can trigger statutory fees and interest as per tax law.

Conclusion

ITR Filing becomes easy when you pick the right form, reconcile numbers, file online, and e-verify on time. For founders, proper ITR Filing also keeps you ready for funding, loans, and big vendor discussions because your financial story looks clean.
