Income Tax Filing in Chennai: ITR Filing Services for Individuals and Businesses (2026)
Income tax return (ITR) filing is the process of reporting income, deductions, tax payments, and other required details to the Income Tax Department. The correct ITR form depends on the taxpayer's category, income sources, and residential status. Key steps include reconciling AIS, TIS, and Form 26AS, selecting the applicable tax regime, calculating tax liability, and completing e-verification within the prescribed period. A filed return is not complete until e-verification is done — unverified returns are treated as not filed.

What Is Income Tax Return Filing?
An income tax return (ITR) is a prescribed statement through which a taxpayer reports income, deductions, tax payments, and other required particulars to the Income Tax Department for an assessment year.
Filing an accurate ITR enables you to:
Who Needs to File an ITR?
Do not assume: Being below the basic exemption limit does not automatically mean ITR filing is optional. Specified transactions and other statutory conditions may create a filing obligation for certain taxpayers.
Income Tax Filing Threshold: Basic Exemption Limit
For FY 2025–26 (AY 2026–27), the applicable basic exemption limit depends on the tax regime and taxpayer category.
However, income below the basic exemption limit does not always mean that ITR filing is optional. Certain taxpayers may still have a filing obligation because of specified conditions or transactions, such as foreign assets, certain high-value transactions, or other requirements applicable for the relevant assessment year.
Similarly, taxpayers may choose to file an ITR even when filing is not mandatory, particularly when they need to claim a refund, carry forward eligible losses, or maintain an official income-tax record.
ITR Form Guide: Which Form Applies to You?
Selecting the wrong ITR form makes the return defective — one of the most common and avoidable filing mistakes.
Common ITR-1 disqualifications: Capital gains of any amount, income from more than one house property, agricultural income above ₹5,000, income as company director, holding unlisted shares, or having foreign assets.
If you received capital gains from selling shares or mutual funds — even small amounts — you likely need ITR-2 or ITR-3, not ITR-1.
AIS, TIS, and Form 26AS: Reconcile Before Filing
This step is skipped by most self-filers and is the single biggest source of post-filing notices.
Before filing, reconcile:
Old vs New Tax Regime: How to Choose

Income Tax Return Due Dates (AY 2026–27)
Due dates vary by taxpayer category. Always verify the current applicable deadline at incometax.gov.in — official extensions and changes are notified there.
Belated return: If the due date is missed, a belated return can generally be filed up to 31 December of the assessment year — with a late fee under Section 234F (up to ₹5,000; ₹1,000 for income up to ₹5 lakh) and interest under Section 234A on unpaid tax.
Updated return (ITR-U): Available under Section 139(8A) for up to 2 years from the end of the relevant assessment year — with additional tax of 25% or 50% on the additional income tax depending on when it is filed.
Do not assume every taxpayer has the same due date. Confirm the applicable deadline for your category and any extensions notified by the Income Tax Department.

ITR Filing by Taxpayer Category
Salaried Employees
Most salaried employees can use ITR-1 or ITR-2 depending on their income profile. Common issues include unreported interest income, missing capital gains disclosures, and incorrect HRA calculations. Reconciling Form 16 with AIS before filing prevents post-filing notices.
Freelancers and Consultants
Freelancers typically report income under "profits and gains from business or profession." Key questions: Is presumptive taxation under Section 44ADA applicable? Are advance tax obligations being met? Are TDS credits from clients correctly reconciled?
Proprietors
Proprietorship income is reported in the proprietor's personal ITR. Assessment of tax audit obligation (Section 44AB), choice of tax regime, and GST reconciliation with business income are all relevant before filing.
Investors
Capital gains from equity shares, mutual funds, and property each have different tax treatment. Equity LTCG above ₹1.25 lakh (FY 2024–25 onwards) is taxable at 12.5%. STCG from listed equity is taxable at 20%. Debt mutual fund gains are taxable as per slab rates. Accurate classification is critical.
Companies
Companies have mandatory ITR filing obligations regardless of income or loss. The applicable form is ITR-6. Audit requirements, MAT assessment, and deferred tax are relevant considerations.
LLPs and Partnership Firms
LLPs use ITR-5. Partner remuneration, interest on capital, and profit-sharing provisions affect the firm's taxable income. Partner-level ITR filing is separate.
Common Income Tax Filing Mistakes
Wrong ITR form
Using ITR-1 when capital gains exist, or using ITR-4 when the turnover exceeds presumptive limits. A defective return requires refiling.
Not reconciling AIS before filing
AIS contains income reported by banks, brokers, employers, and others. Filing without checking AIS frequently results in income mismatches and post-filing notices.
Missing income sources
Interest income from savings accounts, FDs, and bonds; dividend income; rental income; and one-time capital gains are commonly omitted.
Incorrect regime selection
Switching regimes without calculating the tax impact under both options. Business taxpayers switching from old to new regime should check the restrictions on switching back.
Wrong bank details
Incorrect account number or IFSC delays or prevents refund processing.
Not paying advance tax
Taxpayers with total tax liability above ₹10,000 must pay advance tax. Failure to do so attracts interest under Section 234B and 234C.
Skipping e-verification
A return filed but not e-verified within 30 days is treated as if it was never filed.
Claiming ineligible deductions
Deductions under the old regime (80C, 80D, etc.) are not available under the new regime. Claiming them under the new regime is incorrect.
Ignoring the belated return option
Missing the original due date does not mean you cannot file — a belated return can be filed by 31 December of the assessment year.
Real Chennai Example
A software professional in OMR, Chennai had been filing her own ITR-1 every year. For FY 2024–25, she sold equity mutual fund units and received freelance income from a US client through PayPal in addition to her regular salary.
When she approached Aanoor Global before filing:
Issues identified
ITR-1 was not eligible — capital gains and freelance income required ITR-3
AIS showed ₹34,000 in interest income not reported in previous returns
Advance tax had not been paid on the freelance income
The US client payment appeared in AIS under "foreign remittance received" — needed proper disclosure
What Aanoor Global did
Confirmed ITR-3 was the applicable form
Reconciled AIS with her salary, capital gains, interest, and freelance income
Computed advance tax liability and interest under 234B/234C
Prepared the return under both old and new regime — old regime was more beneficial by ₹18,400
Filed ITR-3, guided e-verification, and assisted with advance tax payment for the current year
"I had been filing ITR-1 myself for years without realizing I wasn't eligible once I had capital gains. Aanoor Global caught the form error, reconciled everything with my AIS, and saved me more than the service fee in tax. Very thorough." — Software Professional, OMR, Chennai
Post-Filing: E-Verification and Refund
E-Verification — mandatory after filing
Timeline: E-verification must be completed within 30 days of filing. An unverified return is treated as not filed — the due date interest and late fee implications apply as if no return was submitted.
Refund Processing
If the ITR shows taxes paid in excess of liability, a refund will be processed by the Income Tax Department after the return is verified and processed.
