Why filing your Income-tax Return matters in FY 2026-27 β refund, loss carry-forward, loan eligibility, AIS reconciliation and the right ITR form for your profile.
Filing Income Tax Return
Filing your Income-tax Return (ITR) for AY 2027-28 (FY 2026-27) is more than a statutory obligation β it is the document that unlocks refunds, preserves your right to carry forward losses, supports loan and visa applications, and keeps you insulated from the Income-tax Department's increasingly automated scrutiny machine. With the Annual Information Statement (AIS) now drawing data from over 50 financial reporting sources, the department often knows about your transactions before you have even opened your books. File correctly, file the right form, file on time.
Who Must File an ITR for AY 2027-28
The filing obligation under Section 139(1) of the Income-tax Act, 1961 is wider than most taxpayers realise. Do not use "my income is below the threshold" as your starting point β run through every trigger below first.
Income-Based Triggers
- Any individual whose gross total income (before Chapter VI-A deductions such as Section 80C and 80D) exceeds the basic exemption limit applicable to their chosen regime.
- Under the new tax regime (Section 115BAC), the basic exemption limit is Rs. 3 lakh for individuals below 60 years. Note: the Section 87A rebate may reduce tax payable to nil at higher income levels, but the filing obligation still kicks in once gross income crosses Rs. 3 lakh.
- Under the old tax regime, the basic exemption is Rs. 2.5 lakh (below 60 years), Rs. 3 lakh (60β79 years), and Rs. 5 lakh (80 years and above).
- Every company and firm β including every LLP β must file regardless of whether it made a profit, a loss, or had zero turnover.
- Every resident individual holding foreign assets, foreign bank accounts, or having signing authority over any foreign account.
High-Value Transaction Triggers (Seventh Proviso to Section 139(1))
Even if your income is below the basic exemption, you must file if you:
- Deposited more than Rs. 1 crore in one or more current accounts during the year
- Incurred more than Rs. 2 lakh on foreign travel for yourself or any other person
- Paid electricity bills exceeding Rs. 1 lakh in aggregate during the year
- Claimed TDS or TCS credit exceeding Rs. 25,000 (Rs. 50,000 for senior citizens)
- Had business turnover exceeding Rs. 60 lakh or professional gross receipts exceeding Rs. 10 lakh
Why Filing ITR Matters β Six Practical Reasons
1. Claiming Your Refund
If your employer over-deducted TDS (which happens frequently when you join or leave mid-year, or submit investment proofs late), or you paid advance tax exceeding your actual liability, the excess sits with the government until you file and verify your return. The department does not auto-credit refunds. Pre-validate your bank account on incometax.gov.in before filing to avoid NEFT rejections.
2. Preserving Your Right to Carry Forward Losses
This is the benefit with the hardest deadline β and the most underestimated. Under Sections 72 to 74A:
- Non-speculative business losses: Carried forward for up to 8 assessment years; set off only against business profits.
- Speculative business losses (intraday trading): Carried forward for 4 assessment years; set off only against speculative gains.
- Short-term capital losses: Carried forward for 8 assessment years; can be set off against both STCG and LTCG.
- Long-term capital losses: Carried forward for 8 assessment years; set off only against LTCG.
- Loss from racehorses: Carried forward for 4 assessment years.
The critical rule: If you do not file by the original due date under Section 139(1), you permanently forfeit the right to carry forward business and capital losses. A belated return filed by 31 December 2027 saves you from Section 234F late fees and preserves your refund β but it does NOT save your losses. That right is gone the moment the Section 139(1) deadline passes.
3. Financial Credibility
Banks and NBFCs require the last two to three years' ITR-V acknowledgements as income proof for home loans, LAPs, and top-up facilities. Embassies (UK, Schengen, US) routinely ask for two to three years of filed ITRs. Premium landlords and co-working spaces increasingly ask for ITRs as rental affordability proof. None of these needs are served by a belated return or an absent one.
4. Avoiding AIS-Driven Scrutiny
The AIS pulls data from banks, depositories, mutual fund RTAs, property registrars, insurance companies, and more. If your AIS shows a Rs. 15 lakh equity mutual fund redemption that does not appear in your return, an automated notice under Section 133(6) or Section 142(1) is almost certain. Filing β with proper reconciliation β closes the gap before the department acts on it.
5. Credit Bureau Signalling
A clean three-year filing history with zero outstanding demand under Section 143(1) signals financial discipline. Several digital lending platforms now pull consent-based ITR data directly via the Account Aggregator framework and the income-tax portal API. A missing return year can disqualify you from otherwise approved credit facilities.
6. Government Tenders and Contracts
Most central and state PSU tenders require ITR filings for the last three financial years as a pre-qualification document for turnover or net worth criteria. No ITR = no tender.
Choosing the Correct ITR Form for AY 2027-28
Filing in the wrong form creates a defective return under Section 139(9). The CPC will issue a notice giving you 15 days to refile in the correct form. Miss that window and the return is treated as invalid β with all the consequences of non-filing, including loss of carry-forward rights and Section 234F applicability.
| Form | Who Uses It | Key Situations Where You Cannot Use It |
|---|---|---|
| ITR-1 (Sahaj) | Resident individuals: salary + one house property + other sources; total income β€ Rs. 50 lakh | Director in company; unlisted shares held; foreign assets; any capital gains; agricultural income > Rs. 5,000 |
| ITR-2 | Individuals/HUFs with no business/profession income; capital gains; multiple house properties; foreign assets | Business or professional income of any kind |
| ITR-3 | Individuals/HUFs with business or professional income (not under presumptive scheme) | β |
| ITR-4 (Sugam) | Resident individuals/HUFs/firms (not LLP) opting for presumptive income under Sections 44AD, 44ADA, or 44AE; income β€ Rs. 50 lakh | Director in company; unlisted shares; foreign assets; capital gains on securities |
| ITR-5 | Firms, LLPs, AOPs, BOIs, AJPs | β |
| ITR-6 | Companies (not claiming Section 11 exemption) | β |
| ITR-7 | Trusts, political parties, research associations, charitable institutions | β |
Practical note: If you redeemed even one unit of an equity mutual fund during FY 2026-27 β whether at a gain or a loss β you have capital gains income and cannot use ITR-1. Switch to ITR-2. The same applies if your employer issued ESOPs that vested and were sold during the year.
Due Dates for AY 2027-28 and the True Cost of Missing Them
| Taxpayer Category | Due Date |
|---|---|
| Individuals, HUFs, firms not liable to audit | 31 July 2027 |
| Taxpayers liable to audit under any law | 31 October 2027 |
| Companies and transfer-pricing cases | 30 November 2027 |
| Belated return / revised return | 31 December 2027 |
CBDT has power to extend these dates. Track cbdt.gov.in and the e-filing portal notification feed. Do not assume an extension will come β prepare as though 31 July 2027 is firm.
Section 234F Late Fee: What You Actually Pay
Section 234F imposes a flat fee (not interest) for filing after the Section 139(1) due date:
- Rs. 5,000 β if total income exceeds Rs. 5 lakh and you file on or before 31 December 2027.
- Rs. 1,000 β if total income does not exceed Rs. 5 lakh.
This fee applies even if your tax liability is zero β for instance, if you are filing only to claim a refund or to carry forward a loss. It also applies even if CBDT has extended the due date but you miss the extended date.
Section 234A Interest: The Compounding Penalty
If you have unpaid tax on the filing date, Section 234A levies interest at 1% per month (simple, not compound) on the unpaid amount from the day after the due date to the actual filing date. A part of a month counts as a full month.
- Example: Rs. 80,000 in unpaid tax, filed 4.5 months late = Rs. 80,000 Γ 1% Γ 5 months = Rs. 4,000.
This is in addition to the Section 234F flat fee.
Worked Example: The Real Price of Filing Late
Scenario: Rohan is an independent management consultant. In FY 2026-27, he earns Rs. 20 lakh in professional fees and files under the new tax regime (Section 115BAC). He also redeemed equity mutual fund units during the year and incurred a short-term capital loss of Rs. 1.4 lakh and a long-term capital gain of Rs. 60,000. He misses the 31 July 2027 deadline and files a belated return on 10 November 2027. He had an advance tax shortfall of Rs. 30,000.
Direct penalties:
| Item | Amount |
|---|---|
| Section 234F late fee (income > Rs. 5 lakh, filed before 31 Dec 2027) | Rs. 5,000 |
| Section 234A interest (Rs. 30,000 Γ 1% Γ 4 months) | Rs. 1,200 |
| Total cash outflow | Rs. 6,200 |
The hidden cost β lost carry-forward:
- Rohan's Rs. 1.4 lakh STCG loss cannot be carried forward because he missed the Section 139(1) deadline. The long-term gain of Rs. 60,000 was set off against it within the year β but the remaining Rs. 80,000 STCG loss is permanently lost.
- In FY 2027-28, Rohan sells more equity mutual fund units and books a STCG of Rs. 80,000. Had he carried forward the loss, he would have paid nil tax on this gain. Instead, he pays tax at the applicable STCG rate on the full Rs. 80,000 (rate as notified β verify the current rate for AY 2028-29 on the portal).
- At a 20% STCG rate (applicable to equity/equity-oriented funds as per Finance Act 2024 β confirm if further amended for your assessment year), that is Rs. 16,000 in avoidable future tax, plus cess.
Total avoidable cost of missing one deadline: Rs. 22,200+.
The Rs. 5,000 headline fee was just the beginning.
New Tax Regime vs Old Tax Regime: Making the Right Call for FY 2026-27
Section 115BAC is the default regime from FY 2023-24. Unless you actively opt out, you are assessed under the new regime.
What the New Regime Takes Away
Under the new regime, you cannot claim:
- Section 80C (EPF, ELSS, PPF, life insurance premium, tuition fees) β up to Rs. 1.5 lakh under the old regime
- Section 80D (health insurance premiums)
- Section 80CCD(1B) (additional NPS contribution β Rs. 50,000)
- Section 24(b) deduction on home loan interest for self-occupied property
- House Rent Allowance (HRA) exemption under Section 10(13A)
- Leave Travel Allowance (LTA) exemption
- Standard deduction for salaried employees is available under the new regime (Rs. 75,000 from FY 2024-25 onwards β verify the amount as notified for FY 2026-27)
When the Old Regime Wins
Run the arithmetic honestly in April β not in July when the portal is congested. The old regime generally outperforms the new one if your aggregate verified deductions exceed approximately Rs. 3.75β4.5 lakh (the precise break-even depends on the notified slab rates for FY 2026-27 β use the CBDT tax calculator at incometax.gov.in for precision). Typical old-regime winners:
- Home loan borrowers claiming Rs. 2 lakh Section 24(b) interest + Rs. 1.5 lakh Section 80C + Rs. 50,000 NPS (Section 80CCD(1B)) = Rs. 4 lakh in deductions
- Metro residents with large verified HRA exemptions
How to Switch Regimes
- Salaried taxpayers: Inform your employer in writing at the start of FY 2026-27. If you failed to do so and want to switch in the ITR, you can β but only once per financial year, and your Form 16 and the ITR must reflect the same choice to avoid mismatch.
- Business and professional taxpayers: File Form 10-IEA on the income-tax portal on or before the filing due date. Once you switch back to the old regime, you can return to the new regime only once in your lifetime as a business taxpayer. This is not a decision to reverse lightly.
AIS, Form 26AS and TIS: Reconcile Before You File
The Annual Information Statement (AIS), available on the income-tax portal under the "AIS" tab, is the most important pre-filing document to download. It aggregates over 50 categories of information sourced from financial institutions under the Specified Financial Transaction (SFT) reporting framework, including:
- Salary and TDS (from employers)
- Savings account interest (SFT-001, reported by banks)
- Dividend income (reported by companies/RTAs)
- Mutual fund redemption proceeds (SFT-018, reported by depositories and RTAs)
- Listed equity sale proceeds (SFT-017, reported by brokers)
- Property purchase/sale (SFT-012, reported by registrars)
- Rent received (SFT-011, reported by tenants paying > Rs. 50,000/month)
The Taxpayer Information Summary (TIS) summarises AIS data into aggregate figures that pre-populate the ITR. The pre-filled return is a starting point β not a finished product.
Four-Step Reconciliation Process
- Download your AIS in PDF form. Cross-check each line against your bank statements, broking statements (capital gains report), CAS from CAMS/KFintech, Form 16, and Form 16A.
- Submit AIS feedback for any incorrect entries directly on the portal. The source agency (bank, broker, RTA) gets 30 days to confirm or correct. Even if uncorrected, your feedback creates a record that you disputed the entry.
- Cross-check Form 26AS on the TRACES portal for TDS credits. AIS is broader in scope, but Form 26AS remains the primary legal document for TDS claims in your return.
- File only after reconciliation. Any income visible in AIS but absent from your ITR creates an automatic mismatch. The CPC raises a demand under Section 143(1)(a) for tax on the omitted amount β often months after you thought the return was closed.
Common Mistakes That Create Problems After Filing
Mistake 1: Omitting Bank Accounts
The ITR requires details of every savings and current account held during the year, even zero-balance or dormant accounts. Banks report interest under SFT-001. Omitting an account where interest was credited, even if small, creates an AIS mismatch.
Mistake 2: Forgetting Savings Account Interest
Section 80TTA (old regime) gives a deduction of up to Rs. 10,000 on savings account interest β but the underlying interest must first be included in "Income from Other Sources." Many taxpayers skip both the income and the deduction, creating an AIS mismatch without even getting the tax benefit.
Mistake 3: Regime Mismatch Between Form 16 and ITR
If your employer deducted TDS under the old regime (because you submitted HRA and 80C proofs) but you file the ITR under the new regime, the portal computes tax differently and may show a demand. Verify the regime used in Form 16 Part B before selecting the regime in your ITR.
Mistake 4: Not Verifying Within 30 Days
An unverified ITR is legally equivalent to a return not filed. The 30-day window for e-verification via Aadhaar OTP, net banking, Demat account, or EVC is a hard deadline. If you miss it, you must apply for condonation under Section 119(2)(b) β and approval is discretionary, not guaranteed.
Mistake 5: Assuming ULIP Maturity Is Fully Exempt
Maturity proceeds of ULIPs where annual premiums exceeded Rs. 2.5 lakh are taxable as capital gains. Insurance companies report these under AIS. This is a common omission that generates post-filing demands.
Mistake 6: Discarding Records After the Section 143(1) Intimation
Section 143(1) intimations typically arrive 9β12 months after filing. Reassessment under Section 148 can be initiated up to 10 years in certain cases involving significant suppression. Retain Form 16, Form 16A, ITR-V, Section 143(1) intimation, and all underlying documents for at least 8 years from the relevant assessment year.
Step-by-Step: How to File Your ITR for AY 2027-28
- AprilβMay 2027 β Collect documents: Form 16 (Part A and B from your employer), Form 16A for all non-salary TDS, bank statements, equity and mutual fund capital gains reports, CAS from CAMS/KFintech, rent receipts, home loan certificate from lender.
- Download AIS and TIS from
incometax.gov.in. Run the four-step reconciliation described above. Do not skip this step. - Choose your tax regime by computing tax under both options using the CBDT's official tax calculator (or a reliable CA-reviewed tool). Lock the decision before you open the ITR filing screen.
- Select the correct ITR form using the criteria in the table above. When in doubt between ITR-1 and ITR-2, default to ITR-2.
- Log in to the e-filing portal. Use the pre-filled return as a starting point. Verify every pre-filled figure against your collected documents β do not accept AIS values uncritically.
- Enter income section by section: Salary (Schedule S), house property (Schedule HP β include interest on home loan and annual value), capital gains (Schedule CG β STCG and LTCG separately), and other sources.
- Claim applicable deductions (old regime only): Chapter VI-A items including Section 80C, 80D, 80CCD(1B), 80TTA, 80GG, and others.
- Compute tax and pay any balance: Use the NSDL challan (ITNS 280) via net banking or the payment gateway on the portal. Enter the BSR code, date of deposit, and challan serial number in the ITR under "Tax Paid" schedule.
- Submit the return. Note the 15-digit acknowledgement number. Download the ITR-V immediately.
- E-verify within 30 days: Aadhaar OTP is the fastest method β takes under two minutes. If you prefer physical verification, send the signed ITR-V to CPC Bengaluru by speed post within 30 days.
Key Takeaways
- 31 July 2027 is your primary deadline for non-audit cases. Missing it permanently destroys your right to carry forward business and capital losses β the Section 234F fee is a small fraction of that cost.
- Section 234F imposes a flat late fee of Rs. 5,000 (Rs. 1,000 if income β€ Rs. 5 lakh) regardless of whether you owe any tax. Add Section 234A interest on unpaid tax at 1% per month on top.
- The new tax regime (Section 115BAC) is the default. Opt out actively β salaried employees by informing their employer, business taxpayers by filing Form 10-IEA on time.
- Reconcile AIS before you file, not after. Income in AIS that is absent from your ITR will generate an automatic demand under Section 143(1)(a).
- Wrong ITR form = defective return under Section 139(9). If you have any capital gains, held foreign assets, or are a director in a company, you cannot use ITR-1.
- An unverified return is a non-existent return. Complete e-verification within 30 days of submission β there is no grace period on this.
- Retain all records for at least 8 years: Form 16, Form 16A, ITR-V, Section 143(1) intimation, and all supporting documents β reassessment windows are long and AIS data is stored permanently.
