Partnership Firm Tax Filing Guide for AY 2025–26 in India

The Ultimate 2025 Guide to Partnership Firm Income Tax Filing in India

Hey there, fellow business owner! If you’re part of a partnership firm or thinking about starting one, let’s talk taxes—but in a way that actually makes sense. I know tax season feels like a pain, but once you understand the basics (and a few updates), it’s not so bad. So grab your coffee, and let’s walk through everything you need to know to stay compliant—and maybe even save a few bucks—this year.

First Things First: What’s a Partnership Firm?

A partnership firm is basically a team effort. Two or more people come together to run a business, split profits, and share responsibilities—all laid out in something called a partnership deed. Whether your firm is officially registered or not doesn’t matter much when it comes to income tax. What matters is that you have a proper deed in place.

The Basics:

Partners: The people who’ve joined forces to run the show.
Firm Name: Your business identity.
Partnership Deed: A written agreement that includes profit-sharing ratios, duties, and more.

Latest Income Tax Updates You Shouldn’t Miss (AY 2025–26)

Alright, let’s get to the real stuff. Here’s what’s new this year and what’s still the same:

New Due Dates (Mark Your Calendars)

Non-audit firms: Deadline is now 15th September 2025 (nope, not July 31st anymore).

Audit firms: No change here—still 31st October 2025.

Tax Rates (Nothing Changed Here)

Flat 30% on taxable income

12% surcharge if your income is more than Rs. 1 crore

4% Health & Education cess on the total tax

Alternate Minimum Tax (AMT)

If you're claiming too many deductions, the government has a backup plan—you still pay at least 18.5% of adjusted total income. No skipping the tax man!

Presumptive Taxation: Section 44AD

Running a small firm? You might be eligible for this. If your turnover is up to Rs. 3 crore and 95% of your transactions are digital:

Just declare 8% (or 6% for digital) of your turnover as income

Skip the audit and complex bookkeeping

Which ITR Form to Use?

ITR-5: This is the go-to for most partnership firms.

ITR-4 (Sugam): Only if you’re under presumptive taxation and NOT an LLP.

How to Verify Your Return?

Audit cases: You must use a Digital Signature Certificate (DSC).

Non-audit cases: You’ve got options—DSC, Aadhaar OTP, EVC through net banking or ATM.

And guess what? Only one authorized partner needs to sign now. No need for everyone to get Class 3 DSC.

Deductions You Can Claim

Partner remuneration and interest: As long as it’s clearly stated in your deed and fits within Section 40(b) limits.
Other expenses: Rent, salaries, depreciation, etc.
Interest on capital: Up to 12% annually.
Profit share: Not taxed in the partner’s hands (Section 10(2A)). Nice, right?
