How to File Income Tax Return Online in India — Complete Guide
Filing an income tax return (ITR) is one of the most important legal obligations for every earning individual, business, and organisation in India. Whether you are a salaried employee in Delhi, a self-employed professional in Mumbai, a business owner in Bengaluru, or an NRI with income in India, understanding how to file income tax return correctly and on time is critical. SetupFiling.in simplifies the entire ITR e-filing process for AY 2026-27, offering expert-assisted income tax return filing services across all states and cities in India — backed by CAs, tax experts, and compliance specialists.
The Income Tax Department of India mandates timely ITR filing to avoid penalties, interest, and scrutiny notices. Moreover, a filed ITR serves as strong proof of income for visa applications, bank loans, and government tenders. With setupfiling.in, the process of filing your ITR online becomes completely paperless, fast, and accurate. Our team handles everything — from selecting the correct ITR form and computing total taxable income to claiming eligible deductions, verifying the return, and receiving your income tax refund.
Our Income Tax & Compliance Services
SetupFiling.in is a comprehensive legal and financial compliance platform serving individuals, startups, MSMEs, and corporates across every state in India. Our income tax services cover ITR filing for all taxpayer categories — salaried individuals, freelancers, sole proprietors, partnerships, LLPs, private limited companies, NGOs, and NRIs. Furthermore, we offer a full suite of GST, trademark, Company Registration, and business compliance services, making us your single-window solution for all regulatory needs.
Income Tax Return Filing for Individuals (ITR-1 / ITR-2)
Salaried individuals and those with income from house property or capital gains must file their ITR every year before the due date. The process involves collecting Form 16 from the employer, downloading the Annual Information Statement (AIS), computing total gross income, claiming deductions under Sections 80C, 80D, 80G, and selecting the correct ITR form. SetupFiling.in’s tax experts handle this end-to-end for you — ensuring zero errors and maximum tax savings.
Additionally, individuals with multiple income sources — such as salary, rental income, and investments — need to file ITR-2, which is more complex. Our CAs ensure accurate reporting of all income heads, exempt allowances, and applicable exemptions so you receive the maximum permissible income tax refund. Visit our dedicated income tax return filing for individuals page to know more.
E-Filing Income Tax Return Online
The Income Tax Department’s portal (incometax.gov.in) allows taxpayers to file ITR electronically, a process known as e-filing. However, navigating the portal, uploading documents, selecting the correct schedule, and e-verifying the return can be confusing for first-time filers. SetupFiling.in manages the complete e-filing of income tax return on your behalf — from login and data entry to final submission and Aadhaar-based e-verification.
Moreover, e-filing ensures your return is processed faster, refunds are credited quickly to your bank account, and you receive instant acknowledgement (ITR-V). Consequently, there is no need to physically send any documents to the Income Tax Department. Our team is available 6 days a week to ensure your return is filed correctly and on time for AY 2026-27. File your income tax return with us today.
Income Tax Return Filing for Sole Proprietorship & Business
Business owners and sole proprietors must disclose their business income, expenses, and profit in their ITR using ITR-3 or ITR-4 (Presumptive Taxation Scheme). This includes maintaining books of accounts, computing net business profit, and applying the correct tax rate. SetupFiling.in offers specialised income tax return filing for sole proprietorship businesses — ensuring accurate P&L reporting and maximum deductions.
Furthermore, business owners with turnover exceeding prescribed limits must get their accounts audited before filing. Our Statutory Audit and tax audit team handles this seamlessly. We also assist with advance tax payment calculation and deposit to avoid interest under Sections 234B and 234C.
Back Year / Belated Income Tax Return Filing
Missed filing ITR for a previous year? SetupFiling.in helps you file back year income tax returns for prior assessment years, subject to the provisions of the Income Tax Act. Filing belated or updated returns (ITR-U) helps you regularise your tax position, avoid higher penalties, and maintain a clean compliance record. Therefore, do not delay — contact us at +91 9818209246 to file your pending ITRs today.
Consequently, filing updated returns under Section 139(8A) allows taxpayers to correct mistakes or omissions in originally filed returns within two years from the end of the relevant assessment year. Our team guides you through the entire process, including computation of additional tax liability, interest, and filing fee applicable on updated returns.
Step-by-Step Process: How to File Income Tax Return Online in India for AY 2026-27
Filing your Income Tax Return online in India involves several clearly defined steps. First, gather all essential documents — PAN card, Aadhaar card, Form 16 (from employer), bank account statements, investment proofs for deductions under Chapter VI-A (80C, 80D, 80G), capital gains statements, and rental income details. Subsequently, visit the Income Tax e-filing portal (incometax.gov.in) and log in using your PAN as user ID. For AY 2026-27 (Financial Year 2025-26), the applicable ITR forms are ITR-1 (Sahaj) for salaried individuals with income up to ₹50 lakh, ITR-2 for individuals with capital gains or multiple income sources, ITR-3 and ITR-4 for business and professional income. SetupFiling.in’s experts identify the correct form for your specific income profile — eliminating the risk of filing a defective return.
Once the correct ITR form is selected, taxpayers must fill in all income details, claim applicable deductions, compute total tax liability, and verify whether advance tax or self-assessment tax is payable. If tax is due, it must be paid before submission using Challan 280 on the e-filing portal. Furthermore, the return must be e-verified within 30 days of filing — either through Aadhaar OTP, net banking, bank ATM, or by sending a signed physical copy of ITR-V to CPC Bengaluru. SetupFiling.in handles e-verification instantly using Aadhaar OTP — making the process completely digital and hassle-free. For instance, our team in Delhi NCR (Vaishali, Ghaziabad) assists hundreds of taxpayers every filing season with quick and accurate ITR submissions.
However, many taxpayers make common mistakes while filing ITR — such as selecting the wrong form, omitting income from savings account interest, not reporting freelance income, incorrectly claiming HRA exemption, or missing the deadline. As a result, they receive demand notices from the Income Tax Department, which leads to additional tax, interest, and penalties. Therefore, expert-assisted ITR filing from SetupFiling.in ensures your return is error-free, all exemptions are correctly claimed, and the return is filed well before the due date. In fact, our turnaround time for individual ITR filing is as low as 24–48 hours. Call +91 9818209246 to file your income tax return today.

Frequently Asked Questions (FAQs)
Who is required to file an income tax return in India?
Every individual whose gross total income exceeds the basic exemption limit (₹2.5 lakh under old regime / ₹3 lakh under new regime, ₹3 lakh for senior citizens, ₹5 lakh for super senior citizens) must file an ITR. Additionally, even if income is below the exemption limit, filing is mandatory if you have deposited more than ₹1 crore in a bank account, incurred foreign travel expenses exceeding ₹2 lakh, paid electricity bills exceeding ₹1 lakh, or wish to claim a tax refund. Companies, LLPs, and firms must file ITR regardless of profit or loss. SetupFiling.in provides expert ITR filing for all categories — call +91 9818209246.
What is the due date for filing income tax return for AY 2026-27?
For AY 2026-27 (Financial Year 2025-26), the due dates are: 31st July 2026 for individuals and non-audit cases; 31st October 2026 for businesses requiring audit under the Income Tax Act or Companies Act; and 30th November 2026 for taxpayers required to file transfer pricing reports. Missing the due date attracts a late filing fee of ₹1,000 (income below ₹5 lakh) or ₹5,000 (income above ₹5 lakh) under Section 234F, plus interest on outstanding tax. SetupFiling.in ensures your ITR is filed well before the deadline — contact us at +91 9818209246.
Which ITR form should I use — ITR-1, ITR-2, ITR-3, or ITR-4?
ITR-1 (Sahaj) is for salaried individuals with income from salary, one house property, other sources, and agricultural income up to ₹5,000, with total income not exceeding ₹50 lakh. ITR-2 is for individuals and HUFs with capital gains, income from more than one house property, foreign income, or total income exceeding ₹50 lakh. ITR-3 is for individuals and HUFs with income from business or profession under normal scheme. ITR-4 (Sugam) is for individuals, HUFs, and firms opting for Presumptive Taxation Scheme under Sections 44AD, 44ADA, or 44AE. Selecting the wrong form results in a defective return notice. SetupFiling.in’s experts identify the correct form for your income profile — call +91 9818209246.
How can I file my income tax return online without a CA — can I do it myself?
Yes, taxpayers can self-file their ITR on the Income Tax e-filing portal (incometax.gov.in) by logging in with their PAN, selecting the applicable ITR form, pre-filling from Form 16 and AIS, entering income details, claiming deductions, computing tax, paying any due tax, and e-verifying. However, self-filing carries the risk of errors — wrong form selection, missed income, incorrect deduction claims, and omission of TDS entries — which can result in demand notices. Expert-assisted filing from SetupFiling.in eliminates these risks entirely, ensures maximum refund, and provides full support in case of any subsequent notices — at a very affordable fee. Call +91 9818209246 to get your ITR filed by experts today.
