If you’re a small business owner in India, whether you’re running a proprietorship, partnership firm or private limited company, taxes can feel confusing (and risky).
The income tax slab for small businesses is crucial because it directly affects how much money you keep, what you can reinvest, and how you grow.
In this blog, we’ll explore…
| Quick heads-up! This guide uses the latest rates notified for FY 2025–26 (AY 2026–27) as per trends till now. But always check with your CA or tax expert to match your specific situation. |
For small business owners, taxes aren’t just paperwork. The income tax slab for small businesses you fall into determines…
A higher slab means more tax outflow. Knowing slabs helps you plan investments or expenses that legally reduce tax.
For some, a sole proprietorship is simplest. For others, forming a company could lower overall tax, despite more compliance.
If you underpay or miscalculate, there are hefty interest and fines. Knowing your slabs and planning quarterly advance tax prevents this.
Whether you want to expand, apply for loans or simply take out profits, knowing your tax costs helps you forecast with confidence.
India follows a slab system, which means your income is taxed at different rates in bands. As your income goes up, only the amount above each slab limit is taxed at the higher rate.
This applies mostly to…
Imagine this quick example under the old regime.
So if your business income (after expenses) is ₹12 lakh
Total = ₹1,72,500 + cess.
Unlike individuals, private limited companies, LLPs and partnership firms pay a flat tax on total profits, not slabs.
For example, many companies pay 22% or 25%, partnerships pay 30%, plus cess.
This is why it’s so important to know which structure you’re taxed under. It can completely change your total tax burden.
If you run your business as a sole proprietorship (or you’re a partner, paying tax individually on your share), you have two ways to pay tax in India.
| Income Range | Old Regime | New Regime |
| Up to ₹2.5 lakh | Nil | Nil |
| ₹2.5 – ₹5 lakh | 5% | 5% |
| ₹5 – ₹7.5 lakh | 20% | 10% |
| ₹7.5 – ₹10 lakh | 20% | 15% |
| ₹10 – ₹12.5 lakh | 30% | 20% |
| ₹12.5 – ₹15 lakh | 30% | 25% |
| Above ₹15 lakh | 30% | 30% |
Small business owner tip…
If you have big deductions under 80C, 80D, home loan interest or invest a lot in tax-saving options, the old regime might work better.
If not, the new regime’s simpler, lower rates could save you more.
Taxed as individuals, using either old or new regime slabs.
| Income Range | Old Regime | New Regime |
| Up to ₹2.5 lakh | Nil | Nil |
| ₹2.5 – ₹5 lakh | 5% | 5% |
| ₹5 – ₹7.5 lakh | 20% | 10% |
| ₹7.5 – ₹10 lakh | 20% | 15% |
| ₹10 – ₹12.5 lakh | 30% | 20% |
| ₹12.5 – ₹15 lakh | 30% | 25% |
| Above ₹15 lakh | 30% | 30% |
Both regimes add 4% health & education cess on tax.
Under the old regime, if taxable income < or equal to ₹5 lakh, you get a rebate under 87A, paying zero tax.
This applies to all registered partnership firms & LLPs, regardless of profits.
No slab system here.
No slabs. It’s a flat rate on total profits.
This is why many growing businesses move from proprietorship to a company or LLP. Beyond certain profit levels, a flat corporate tax can be more attractive than personal slabs.
Applies if taxable income exceeds ₹1 crore. For most MSMEs below this, not a worry.
4% health & education cess on total tax (including surcharge, if any).
Simple example for clarity!
Why does this matter to small business owners?
| Business Type | Tax Rate | Notes |
| Sole Proprietor / Individual | Slab-based:5%, 10%, 15%, 20%, 25%, 30% under new regime | The old regime allows deductions (80C, 80D, etc.). New regime gives lower rates, fewer deductions. |
| Partnership Firm / LLP | 30% flat + 4% cess | No slabs. Partners are also taxed individually on salaries/interest from the firm. |
| Private Limited Company | 22% under Sec 115BAA(approx. 25.17% effective) | Must forgo most deductions. Older companies pay 25% if turnover < ₹400 cr. |
| New Manufacturing Co. (115BAB) | 15% flat (approx. 17.16% effective) | Only for new units set up under strict timelines. |
Quick example
A small service business making ₹15 lakh profit pays…
Key takeaway!
For small profits, individual tax under the slab may work out cheaper. As profits grow, LLPs & companies with flat rates can become more tax-efficient.
The old tax regime is the traditional way most Indians have calculated taxes for decades.
Because it allows you to claim a wide range of deductions and exemptions, like:
If you or your business heavily invest in tax-saving instruments, have home loans, or medical policies, the old regime can lower your taxable income a lot, even if the slab rates are slightly higher.
A quick contrast!
| Feature | Old Regime | New Regime |
| Deductions & Exemptions | Many allowed | Most not allowed |
| Slab rates | Slightly higher | Generally lower |
| Good for | Those with lots of tax-saving investments | Those with fewer deductions |
Small business example…
A sole proprietor paying hefty life insurance premiums and repaying a home loan might still save more under the old regime.
Tax isn’t just about filing returns. Smart planning ensures you keep more profits to reinvest in your business.
Use simple accounting software or even Excel to track all sales, purchases, and expenses. This helps claim every legitimate deduction.
Have a dedicated current account for your business. Keeps things clear for audits and easier to justify expenses.
Your business grows, and loans get paid off. Sometimes switching from the old to the new regime (or back) saves lakhs.
Under old regime, use 80C, 80D, 80E etc. For partnerships & companies, track depreciation & professional expenses.
Reinvest in assets that are tax-deductible (like new machinery or IT systems under section 32).
Pay advance tax quarterly if liable. Missed payments mean 1% monthly interest under sections 234B & 234C.
A good CA will more than pay for themselves by helping reduce your tax burden and ensuring you stay penalty-free.
Clear team, personal, functional, and financial goals drive growth, but clarity is only the first step.

Calculating your tax doesn’t have to be intimidating. Here’s a basic way to do it based on your business type.
Revenue – allowable business expenses.
Interest, rent, salary, etc.
Based on taxable income after deductions (if in old regime).
Revenue – expenses, depreciation.
Partners then pay tax individually on salary or interest received from firm.
Example for a small manufacturer (partnership firm)…
Always work closely with your CA. They can help you adjust depreciation, carry forward losses, or use eligible deductions to legally reduce tax.
Taxes may seem scary, but understanding your income tax slab for small business, planning smartly, and keeping good records makes it so much easier.
Tax saved is profit earned.
So, get proactive. Review your structure, talk to your CA, and keep more money to build the life (and business) you dreamed of.
