Expert-assisted income tax return filing for freelancers, self-employed professionals, proprietors, and individuals with business or professional income. We help you choose the correct ITR form, review deductions, compare tax regimes, and file accurately.
If you earn income from business or profession, your tax return usually needs more review than a standard salary return. Business income filing may involve form selection, presumptive taxation, deductions, TDS reconciliation, audit documents, and tax regime decisions.
Taxbrain helps simplify that process. Whether you are filing ITR-3 or ITR-4, we support you with practical review and filing assistance for AY 2026-27.

ITR-3 filing
ITR-3 is applicable to individuals and HUFs having income from salary or pension, house property, profits and gains of business or profession, capital gains, or income from other sources, where they are not eligible to file ITR-1, ITR-2, or ITR-4. It is generally used for more detailed business or professional income reporting.
This is usually the right route when your return includes full business disclosures, books of account, capital gains, or other conditions that make simplified filing unsuitable.
ITR-4 (Sugam) filing
ITR-4 is a simplified return for resident individuals, resident HUFs, and resident firms other than LLPs, where total income does not exceed ₹50 lakh and business or professional income is computed under presumptive taxation under sections 44AD, 44ADA, or 44AE. It can also include salary or pension, other sources, agricultural income up to ₹5,000, and section 112A capital gains up to ₹1.25 lakh.
ITR-4 is not mandatory even if eligible. It is a simplified option available to taxpayers who qualify for presumptive taxation and prefer that route.
Who cannot use ITR-4
ITR-4 cannot be used if the taxpayer:
- Is a director in a company.
- Has short-term capital gains.
- Has long-term capital gain under section 112A exceeding ₹1.25 lakh.
- Held any unlisted equity shares during the previous year.
- Has foreign assets, foreign signing authority, or foreign income.
- Has deferred tax on ESOPs.
- Has brought-forward loss or loss to be carried forward.
- Has total income above ₹50 lakh.
- Has income from a retirement benefit account covered under section 89A cases listed in the official guidance.
- Has income chargeable at special rates.
This is why choosing the right form matters. Taxbrain reviews your eligibility before filing so the return form matches your actual tax position.

Tax regime guidance
The new tax regime under section 115BAC is the default regime for eligible individual taxpayers. Eligible taxpayers still have the option to opt out and choose the old regime, depending on the applicable rules.
Non-business cases
In non-business cases, the tax regime choice can generally be exercised every year directly in the ITR, provided the return is filed on or before the due date under section 139(1).
Business and profession cases
For taxpayers with business or professional income, opting out of the default regime requires filing Form 10-IEA on or before the due date under section 139(1). Re-entering the default regime must also be done through Form 10-IEA, and the option to withdraw old regime and re-enter the new regime is available only in a subsequent assessment year and only once in a lifetime for eligible business/profession taxpayers.
This decision can affect your filing not just this year, but future years too. Taxbrain helps review both regimes before filing.
Tax slabs for AY 2026-27
The old and new regimes follow different slab structures. Under the old regime, slabs also vary based on age category.
Individuals below 60 years
Individuals aged 60 years or more but less than 80 years
Under the old regime, nil tax applies up to ₹3,00,000, then 5 percent up to ₹5,00,000, 20 percent up to ₹10,00,000, and 30 percent above ₹10,00,000. Under the new regime, the same default slab structure applies beginning with nil tax up to ₹4,00,000.
Individuals aged 80 years or more
Under the old regime, nil tax applies up to ₹5,00,000, then 20 percent up to ₹10,00,000, and 30 percent above ₹10,00,000. Under the new regime, the same default new regime slab structure applies beginning with nil tax up to ₹4,00,000.
Surcharge, rebate, cess, and marginal relief
Applicable surcharge rates in the official guidance are nil up to ₹50 lakh, 10 percent from ₹50 lakh to ₹1 crore, 15 percent from ₹1 crore to ₹2 crore, 25 percent from ₹2 crore to ₹5 crore, and above ₹5 crore the rate is 25 percent in the new regime and 37 percent in the old regime. The official note also states that enhanced surcharge is generally not levied on income taxable under sections 111A, 112, 112A, and dividend income beyond the stated cap.
Resident individuals may also get rebate under section 87A. The shared AY 2026-27 data states the rebate is up to ₹60,000 under the new regime where taxable income does not exceed ₹12,00,000, and up to ₹12,500 under the old regime where taxable income does not exceed ₹5,00,000.
Health and Education Cess at 4 percent applies on income tax plus surcharge in both regimes. Marginal relief may also apply where income crosses specific surcharge thresholds.
Deductions under the new regime
The new regime allows fewer deductions, so it is important to review what is still available before filing.
Section 24(b)
Deduction from income from house property for interest on housing loan for let-out property is available, with actual value allowed without limit, though resulting loss under the head cannot be set off against other heads or carried forward in the manner described in the shared source data.
Section 80CCD(2)
Deduction is available for employer contribution to pension scheme, with the source data listing up to 14 percent of salary for the relevant employer categories mentioned on the page.
Section 80CCH
Contribution to the Agnipath Scheme and the Agniveer Corpus Fund is deductible to the extent stated in the official guidance, including eligible government contribution.
Deductions under the old regime
The old regime allows a wider range of deductions, which is why many taxpayers with business or professional income still compare both regimes carefully before filing.

FAQ’s
Which ITR form should I use if I have business or professional income?
Usually ITR-3 or ITR-4 will apply, depending on your eligibility, income type, and whether presumptive taxation is being used. ITR-4 is available only to eligible resident taxpayers meeting the specified conditions.
Can I file ITR-4 if I have salary and freelance income?
You may be able to use ITR-4 if your business or professional income is computed on a presumptive basis, total income does not exceed ₹50 lakh, and all other ITR-4 conditions are satisfied. Otherwise, ITR-3 may be required.
Can I use ITR-4 if I have capital gains?
ITR-4 can include only limited long-term capital gains under section 112A up to ₹1.25 lakh. Short-term capital gains or higher ineligible capital-gain cases make ITR-4 unavailable.
Is the new tax regime mandatory?
The new regime is the default regime for eligible taxpayers, but eligible taxpayers can opt out and choose the old regime subject to the applicable rules. Business/profession taxpayers must use Form 10-IEA for this choice.
What documents should I keep ready?
Common documents include PAN, Aadhaar, books or income summary, Form 16A, Form 26AS, AIS, bank statements, challans, and deduction-related proofs. Additional reports may be needed in audit or transaction-heavy cases.
What is the rebate under section 87A for AY 2026-27?
The shared AY 2026-27 data states that rebate is up to ₹60,000 under the new regime where taxable income does not exceed ₹12,00,000, and up to ₹12,500 under the old regime where taxable income does not exceed ₹5,00,000.
