Tax filing in India for AY 2026-27 (FY 2025-26) has one major change from prior years: the new tax regime is now the default. If you don't actively opt for the old regime, the IT department will apply the new regime slabs automatically. For the 63% of salaried filers with modest deductions, this is net positive — lower rates, less paperwork. For the 37% with significant 80C investments, HRA claims, and home loan interest, the old regime still saves more. This guide covers every ITR form, every filing method, every major deduction, and the exact steps to file — from AIS download to e-verification.
- New regime is default for AY 2026-27. Standard deduction raised to ₹75,000 (both regimes).
- ITR-1 filers with RSU income, F&O losses, or two house properties must switch to ITR-2 or ITR-3.
- Deadline: July 31, 2026 for individuals without audit. Belated: December 31, 2026 (with penalty).
- E-verification via Aadhaar OTP completes the filing — do this within 30 days of filing.
- CBDT processed 8.5 crore ITRs for AY 2025-26 — the portal handles it, but avoid peak July weeks.
Who must file income tax in India for AY 2026-27?
Filing is mandatory for any individual, HUF, firm, company, or trust with taxable income. For individuals, the basic exemption limits are:
| Age | Old regime | New regime |
|---|---|---|
| Below 60 | ₹2.5 lakh | ₹3 lakh |
| 60–80 (senior) | ₹3 lakh | ₹3 lakh |
| Above 80 (super senior) | ₹5 lakh | ₹3 lakh |
Filing is also mandatory regardless of income if you: own foreign assets, are a signing authority on a foreign account, paid electricity bills above ₹1 lakh, deposited more than ₹1 crore in a current account, made foreign remittances above ₹7 lakh under LRS, or spent above ₹2 lakh on foreign travel. High-value transaction thresholds ensure the IT Department picks up affluent non-filers through AIS data.
Choosing the right ITR form — the decision tree
Picking the wrong form is the single most common filing error in India. The consequence: a Section 139(9) defective return notice, requiring a response within 15 days and often a complete refiling.
ITR-1 (Sahaj) — for the simplest cases
Eligible: Individuals with salary / pension from one employer + interest income + one self-occupied house property. Total income must be below ₹50 lakh.Not eligible if: You have capital gains from shares or property, income from two or more house properties, business / professional income, foreign assets, or RSU / ESOP perquisites. Many salaried employees incorrectly file ITR-1 when they should file ITR-2. Check your Form 12BA and AIS before defaulting to ITR-1.
ITR-2 — for most salaried professionals with investments
Eligible: Salary + capital gains (shares, MF, property), multiple house properties, foreign assets, RSU / ESOP income, directorship in a company, foreign travel above ₹2 lakh. ITR-2 is the workhorse form for India's salaried-professional class. Schedule CG captures equity STCG (20%), equity LTCG above ₹1.25 lakh (12.5%), and property capital gains separately.
ITR-3 — business and professional income
Eligible: Business income (ITR-3 includes full P&L), professional income above the 44ADA limit, F&O trading (always ITR-3 — F&O is non-speculative business income), partnership firm partners receiving salary or interest from the firm.
ITR-4 (Sugam) — presumptive taxpayers
Eligible: Businesses under Section 44AD (up to ₹2 crore turnover, declare 8% or 6% of turnover as income), professionals under Section 44ADA (up to ₹50 lakh receipts, declare 50% as income), transport operators under Section 44AE.Cannot file ITR-4 if: You are a director in a company, hold unlisted equity, or have capital gains — switch to ITR-3 in those cases.
| Your situation | ITR form |
|---|---|
| Salaried, one employer, no capital gains, < ₹50L income | ITR-1 |
| Salaried + RSU / ESOP / equity / MF / property gains | ITR-2 |
| Freelancer, consultant (receipts below ₹50L) | ITR-4 (44ADA) |
| Freelancer / consultant with capital gains or directorship | ITR-3 |
| F&O trader, crypto trader, small business owner | ITR-3 |
| Small business (turnover < ₹2 crore, no capital gains) | ITR-4 (44AD) |
Old vs new regime — which saves more in AY 2026-27?
The new regime has lower slab rates but eliminates most deductions. The old regime has higher rates but allows 80C, 80D, HRA, home loan interest, and other deductions.
| Income slab | Old regime rate | New regime rate |
|---|---|---|
| Up to ₹3 lakh | Nil | Nil |
| ₹3–7 lakh | 5% | 5% |
| ₹7–10 lakh | 20% | 10% |
| ₹10–12 lakh | 20% | 15% |
| ₹12–15 lakh | 30% | 20% |
| Above ₹15 lakh | 30% | 30% |
For most people earning ₹8–15 lakh, the new regime wins if total deductions (80C + 80D + HRA + home loan interest) are below ₹3.5–4 lakh. Above that threshold, the old regime saves more. Both regimes now have a ₹75,000 standard deduction. Let a CA compare both regimes for your specific case before you file — the difference can be ₹15,000–₹40,000 for a ₹15 lakh salary.

How do I check my income tax refund status?
Log in to incometax.gov.in → e-File → Income Tax Returns → View Filed Returns. The refund status shows as "Refund Issued," "Refund Failed," or "Refund in Process." If refund has failed, check that your bank account is pre-validated and the IFSC is current. Call 1800-103-4455 or email refunds@incometaxindia.gov.in for refund issues beyond 60 days.
I received an AIS / 26AS mismatch notice — what do I do?
Section 143(1)(a) intimations flag AIS entries that don't appear in the filed return. You have 30 days to respond: either accept the demand and pay (if the AIS entry is correct) or dispute with evidence (if it's a mis-categorised transaction or duplicate entry). Don't ignore these notices — they become confirmed demands after 30 days.

What should you verify before using this Income Tax guide?
Before acting on tax filing in india 2026, verify the current rules or platform behavior with the Income Tax Portal. The practical answer depends on your business model, state, turnover, documents, software stack, and whether the decision affects tax, customer data, paid media spend, or a production workflow.
Use this article as a working checklist, then confirm forms, due dates, AIS or Form 26AS data, regime rules, and filing instructions. In our audits, most expensive mistakes do not come from ignoring the whole process. They come from one stale assumption, one mismatched address, one missing event, or one automation path that nobody tested after launch.
| Checkpoint | Why it matters | Where to confirm |
|---|---|---|
| Current rule or platform status | Limits, forms, policies, and APIs can change after a blog update. | Income Tax Portal |
| Your exact business case | A local shop, freelancer, D2C store, agency, and SaaS team rarely need the same next step. | Documents, invoices, campaign data, analytics setup, or workflow logs |
| Implementation evidence | The safest filing decision is backed by proof, not memory or screenshots from an old setup. | Portal acknowledgement, dashboard export, invoice sample, test lead, or error log |
How do we apply this in real business work?
We start with the smallest decision that can be verified. For compliance work, that means matching PAN, address, bank, invoices, and portal status before filing. For websites, marketing, analytics, and automation, it means testing the real user path from first click to final record. The boring checks catch the costly failures.
A useful rule: if a claim changes money, tax, reporting, or customer communication, keep evidence for it. Save the acknowledgement, export the report, test the form, and note the date you verified the source. That gives you a clean trail when a client, officer, platform, or internal team asks why the setup was done that way.
When should you get expert review?
Get expert review when the next action can create tax exposure, lost reporting data, ad waste, broken customer communication, or production downtime. A simple self-check is enough for low-risk learning. A filed return, new registration, tracking migration, paid campaign restructure, or live automation deserves a second set of eyes before it affects customers or records.
How often should this be rechecked?
Recheck the decision whenever your turnover, state, product mix, campaign budget, website stack, analytics property, or workflow ownership changes. Also recheck it after major portal updates, platform policy changes, annual filing deadlines, and vendor migrations. The guide is useful today only if the facts behind it still match your business.
What is the fastest safe way to decide?
Write the decision in one sentence, list the proof needed for that sentence, and verify only those items first. This keeps the work focused. If the proof confirms the decision, proceed. If one item is unclear, pause and resolve that point before changing filings, campaigns, tracking, website code, or automation logic.
What can go wrong if you skip verification?
The usual failure is not dramatic at first. It looks like a rejected application, a wrong tax invoice, a missing conversion, a duplicate lead, a broken report, or a workflow that silently stops. Those small failures become expensive when nobody notices them until month-end reporting, filing day, or a customer escalation.
What evidence should you keep after making the change?
Keep enough evidence to reconstruct the decision later. For a compliance topic, that usually means the application reference number, registration certificate, invoice sample, return acknowledgement, payment challan, notice reply, or source link checked on the day of filing. For a website, campaign, analytics setup, or automation, keep the before-and-after screenshot, test submission, dashboard export, webhook log, and the exact setting that changed.
This matters because most business fixes are revisited months later, when nobody remembers the original reason. A short evidence trail makes audits faster, handovers cleaner, and vendor conversations more precise. It also keeps the advice in this guide tied to your real operating context instead of becoming a generic checklist that gets copied without review.
- Date checked: record when the official source, dashboard, or portal screen was reviewed.
- Business context: note the entity, state, product, campaign, property, or workflow affected.
- Proof of action: save the acknowledgement, report export, test result, or live URL.
- Owner: assign one person to re-check the item when rules, tools, or business volume change.
Which next step should you take after reading this?
Turn the article into one action list. Mark what is already true, what needs proof, and what needs expert review. If you want to go deeper, compare this guide with finance and compliance services, finance calculators and tools, and compliance review. Then update the decision only after the official source and your own records agree.
Frequently asked questions
Who is required to file income tax in India for AY 2026-27?
Any individual with gross total income above the basic exemption limit: ₹2.5 lakh under old regime; ₹3 lakh under new regime. Senior citizens (60–80): ₹3 lakh (old) / ₹3 lakh (new).

Filing is also mandatory if you have foreign assets, signing authority on a foreign account, paid electricity bills above ₹1 lakh in the year, or deposited more than ₹1 crore in current accounts.

New regime is default for AY 2026-27. It benefits filers with fewer deductions (no 80C, 80D, or HRA allowed). Old regime is better if your deductions under 80C + 80D + HRA + home loan interest exceed roughly ₹3.75 lakh. Compute both scenarios — or let Bizeract's CA do it — before filing.

ITR-1 (Sahaj): salaried, single employer, income below ₹50 lakh, no capital gains. ITR-2: salary + capital gains, multiple house properties, foreign assets.
