ITR Filing Checklist AY 2026-27

ITR Filing Checklist for AY 2026-27: The Complete Guide for Indian Taxpayers

Filing your Income Tax Return (ITR) is one of the most important financial tasks you will complete every year. Yet millions of Indians either miss the deadline, file incorrectly, or leave money on the table by forgetting key deductions. This comprehensive guide will walk you through every document you need, every deduction you can claim, and every step of the process for Assessment Year 2026-27 (Financial Year 2025-26).

Whether you are a salaried employee in Mumbai, a freelancer in Bengaluru, or a government employee in Delhi, this checklist ensures you never miss a document, never forget a deduction, and always file on time.

Which ITR Form Should You File?

Choosing the wrong ITR form is one of the most common mistakes Indian taxpayers make. Filing in the wrong form means your return is considered defective, and you may receive a notice from the Income Tax Department. Here is a clear breakdown:

ITR-1 (Sahaj) — For Simple Salaried Cases

ITR-1 is the simplest form, suitable for the majority of salaried employees in India. You can use ITR-1 if all the following conditions are met:

• Total income does not exceed ₹50 lakh in FY 2025-26
• Income is from salary or pension only
• You have income from one house property (self-occupied or let out)
• Other income includes only savings account interest, FD interest, or family pension
• You are a resident Indian (not NRI or RNOR)
• You do NOT have capital gains from shares, mutual funds, or property
• Agricultural income does not exceed ₹5,000

Who cannot use ITR-1: If you sold shares or mutual funds in FY 2025-26 (even a single unit of ELSS or any equity fund), you must file ITR-2, not ITR-1. This is a very common error — many salaried employees who use ELSS SIPs for Section 80C do not realize they need to switch to ITR-2 when they redeem or switch any fund.

ITR-2 — For Capital Gains, Multiple Properties, NRIs

ITR-2 is for individuals and HUFs who have income from capital gains (shares, mutual funds, property) or income from more than one house property. Use ITR-2 if:

• You sold equity shares, mutual funds, or property during FY 2025-26
• You have income from more than one house property
• You are an NRI or RNOR
• You have foreign income or foreign assets
• You have income from lottery, horse racing, or speculative trading
• Your total income exceeds ₹50 lakh

ITR-3 — For Business and Professional Income

ITR-3 is for individuals or HUFs who have income from business or profession (proprietary business, freelancers, consultants, doctors, lawyers). If you run a shop, a consulting practice, or any proprietary business, you file ITR-3. This form requires you to report your business income under the head "Profits and Gains of Business or Profession" (PGBP).

ITR-4 (Sugam) — For Presumptive Taxation

ITR-4 is for small businesses and professionals who opt for the presumptive taxation scheme under Section 44AD (for businesses with turnover up to ₹3 crore) or Section 44ADA (for professionals with gross receipts up to ₹75 lakh). This is very popular with freelancers, small traders, and self-employed professionals in India.

Complete Document-by-Document Checklist for AY 2026-27

Category 1: Basic Identity and Registration Documents

Before you even open the Income Tax e-filing portal, ensure these basics are in order. These are not just documents to carry — they must be verified and linked on the portal:

PAN-Aadhaar Linking Status: Check your PAN-Aadhaar link status on incometax.gov.in before you start filing. If your PAN is inoperative due to non-linking, your TDS will be deducted at higher rates, and you may not be able to file.

Category 2: Salaried Income Documents

Form 16 — The Most Important Document for Salaried Employees

Form 16 is issued by your employer and is the cornerstone of your ITR filing. It has two parts:

• Part A: Summary of TDS deducted by the employer, linked to your PAN. This is auto-populated in Form 26AS and should match exactly.
• Part B: Detailed breakup of your salary, perquisites, allowances, and the deductions your employer has considered (HRA, LTA, professional tax, Section 80C investments declared by you). Part B is the annexure that you use to fill your ITR.

Important: If you changed jobs during FY 2025-26, you will receive two Form 16 documents — one from each employer. Both must be combined while filing your ITR. The previous employer may or may not have considered your other employer's salary while computing TDS, so there is a high chance of a tax shortfall that you must pay as self-assessment tax before filing.

Form 16 must be issued by your employer by June 15, 2026. If you have not received it by then, follow up with your HR or payroll team immediately.

Form 16A — TDS Certificate from Banks and Others

If your bank deducts TDS on Fixed Deposit interest, they issue Form 16A. Similarly, clients deducting TDS on freelance or consulting payments also give Form 16A. Collect Form 16A from:

• All banks where you have FDs (interest income is taxable as per your slab)
• Any client or company that paid you consulting fees and deducted TDS
• Mutual fund companies for dividend income where TDS was deducted

Category 3: Tax Credit Documents — Form 26AS and AIS/TIS

These two documents from the Income Tax Department are arguably more important than Form 16, because they reflect what the department actually knows about your income and taxes paid.

Form 26AS — Tax Credit Statement

Form 26AS is your tax passbook. It shows every rupee of TDS deducted against your PAN, advance tax paid, self-assessment tax paid, and refunds received. Download it from incometax.gov.in → View Form 26AS.

What to verify in Form 26AS:

• TDS from employer should match Form 16 Part A exactly
• TDS from bank FDs should match Form 16A
• Any advance tax or self-assessment tax you paid should appear here
• Check for any TDS entries that you do not recognise — these could indicate income you forgot about

Annual Information Statement (AIS) and Taxpayer Information Summary (TIS)

AIS is a more comprehensive statement introduced in recent years. It shows not just TDS but also information reported by third parties: stock market transactions, mutual fund purchases and redemptions, property registrations, foreign remittances, GST turnover, dividend income, and more.

The AIS is critical because if you do not report something that appears in your AIS, the Income Tax Department's AI-powered systems will likely send you a notice. Always cross-check your ITR with AIS before filing.

Category 4: Section 80C Investment Proofs (₹1.5 Lakh Limit)

Section 80C is the most popular deduction in India, allowing a reduction of up to ₹1,50,000 from your taxable income. Here is the complete list of investments and expenses that qualify, along with the documents you need:

Remember: The aggregate of all 80C investments is capped at ₹1,50,000. Investing more than this gives you no additional tax benefit. However, you can invest more for wealth creation purposes — just do not expect a deduction beyond ₹1.5 lakh.

Category 5: Section 80D — Health Insurance Deduction

Section 80D gives you a deduction for health insurance premiums paid for yourself, spouse, children, and parents. The limits are:

• For self, spouse, and children: ₹25,000 per year (₹50,000 if you are a senior citizen aged 60+)
• For parents: Additional ₹25,000 per year (₹50,000 if parents are senior citizens)
• Maximum deduction possible: ₹1,00,000 (if both you and your parents are senior citizens)
• Preventive health check-up: ₹5,000 included within the above limits

Documents required: Health insurance premium receipts from insurer, or premium payment confirmation email/SMS. If you have a group health policy from your employer, you can claim only for the premiums you paid yourself (not employer contributions).

Category 6: HRA (House Rent Allowance) Documents

HRA exemption is available to salaried employees living in rented accommodation. It is one of the largest tax-saving benefits for employees in metro cities like Mumbai, Delhi, Bengaluru, Chennai, Hyderabad, and Kolkata.

The HRA exemption is the lowest of:

• Actual HRA received from employer
• 50% of basic salary (for metro cities) or 40% (for non-metro cities)
• Actual rent paid minus 10% of basic salary

Documents for HRA claim:

• Rent receipts for every month of the financial year (April 2025 to March 2026)
• Rent agreement / lease agreement
• Landlord's PAN card (mandatory if annual rent exceeds ₹1,00,000 — i.e., monthly rent above ₹8,333)
• Bank statements showing rent transfer (if you pay by NEFT/IMPS/cheque)

Category 7: Home Loan Deductions (Section 24b and 80EEA)

If you have a home loan, you can claim deductions on both the principal repayment and the interest paid:

• Section 24(b) — Interest on housing loan: Up to ₹2,00,000 per year for a self-occupied property. If the property is let out, the entire interest is deductible (but set off against house property income is limited).
• Section 80C — Principal repayment: Within the ₹1.5 lakh 80C limit.
• Section 80EEA — First-time buyers: Additional ₹1,50,000 for first-time home buyers under the affordable housing scheme (loan sanctioned between April 2019 and March 2022 — check if applicable).

Documents required:

• Home loan interest certificate for FY 2025-26 (from your bank / NBFC / HFC)
• Home loan statement showing principal and interest bifurcation for each EMI
• Possession letter or registration certificate of the property
• If joint loan: details of co-borrower's share

Category 8: Capital Gains Documents

If you traded stocks, redeemed mutual funds, sold property, or sold any capital asset in FY 2025-26, you need capital gains statements:

Note on Budget 2024 changes: The July 2024 Union Budget changed LTCG on equities and equity mutual funds from 10% to 12.5%, and the exemption limit increased from ₹1 lakh to ₹1.25 lakh. STCG on equities changed from 15% to 20%. These new rates apply to sales made after July 23, 2024. Sales before that date are taxed at the old rates. Your broker's P&L report should handle this split automatically.

New Tax Regime vs Old Tax Regime: Which Is Better for AY 2026-27?

This is the biggest decision you will make when filing your ITR. For AY 2026-27, the New Tax Regime is the default — you have to actively opt for the Old Regime if you want to claim deductions like 80C, 80D, HRA, home loan interest, etc.

New Tax Regime Slab Rates (AY 2026-27)

Key features of New Regime: Standard deduction of ₹75,000, rebate under Section 87A (zero tax up to ₹12 lakh income for non-capital gains income), no requirement for investment proofs. No 80C, 80D, HRA, home loan interest deductions allowed.

Old Tax Regime Slab Rates (AY 2026-27)

When Old Regime wins: If your total deductions (80C + 80D + HRA + home loan interest + NPS + other deductions) exceed approximately ₹3.75 lakh for someone in the ₹15-20 lakh income bracket, the old regime saves more tax.

Old vs New Regime — A Practical Comparison Table

Other Important Deductions to Claim

Section 80E — Education Loan Interest

If you took an education loan for higher studies (your own, spouse, children, or students under your legal guardianship), the entire interest paid is deductible under Section 80E — there is no upper limit on the deduction amount. Available for 8 years from the year you start repaying the loan. Document needed: Interest certificate from your bank or NBFC showing the interest portion of EMIs paid in FY 2025-26.

Section 80G — Donations to Charitable Institutions

Donations to approved charitable institutions are deductible under Section 80G. Depending on the institution, the deduction is 50% or 100% of the donation amount, with or without a qualifying limit. Donations to PM Relief Fund, Chief Minister's Relief Fund, and certain national institutions qualify for 100% deduction without any limit. Document needed: Donation receipt with the institution's 80G registration number and your PAN mentioned. Without a valid receipt and registration number, the deduction will be disallowed.

Section 80CCD(1B) — NPS Tier 1 Additional Deduction

Over and above the 80C limit of ₹1.5 lakh, you can claim an additional deduction of up to ₹50,000 for contributions to NPS Tier 1 under Section 80CCD(1B). This is exclusive to NPS — no other investment qualifies for this additional ₹50,000 deduction. Available only under the Old Tax Regime. Document needed: NPS contribution statement from NSDL/Karvy CAS portal.

Section 80TTA / 80TTB — Savings Account Interest

• Section 80TTA: Deduction up to ₹10,000 on savings account interest for non-senior citizens.
• Section 80TTB: Deduction up to ₹50,000 on interest from savings accounts, FDs, and recurring deposits for senior citizens (aged 60+). Replaces 80TTA for seniors.

Step-by-Step Guide: How to File Your ITR Online for AY 2026-27

Here is the complete process to file your ITR on the Income Tax e-filing portal (incometax.gov.in):

1. Login to incometax.gov.in using your PAN and password. If you are a first-time user, register using your PAN.
2. Go to e-File → Income Tax Returns → File Income Tax Return.
3. Select Assessment Year: Choose AY 2026-27 for income earned in FY 2025-26 (April 2025 to March 2026).
4. Select Mode of Filing: Choose Online (easier for salaried) or Offline (XML upload for complex cases).
5. Select ITR Form: Based on your income type (ITR-1, ITR-2, ITR-3, or ITR-4).
6. Select Reason for Filing: Typically "Taxable income is above basic exemption limit" or "Other."
7. Fill Pre-filled Information: The portal pre-fills data from Form 16, AIS, and 26AS. Verify every pre-filled field carefully — employers sometimes report incorrect figures.
8. Choose Tax Regime: The portal will ask you to choose Old or New regime. You can use a built-in comparison tool on the portal. Note: Salaried employees can switch regime every year. Business owners who chose Old Regime previously need to file Form 10-IEA to opt out.
9. Add Income from Other Sources: Manually enter FD interest, savings interest, dividend, rental income, freelance income not shown in pre-fill.
10. Claim Deductions: Under the Old Regime, fill in all your deductions under Chapter VI-A (80C, 80D, 80E, 80G, etc.).
11. Review Tax Computation: Check your tax liability. If there is tax payable, pay self-assessment tax via Challan 280 before submitting.
12. Submit and E-Verify: Submit the return and e-verify it within 30 days using Aadhaar OTP, net banking, bank ATM, Demat account, or by sending physical ITR-V to CPC Bengaluru. E-verification is mandatory — unverified returns are treated as not filed.

Common Mistakes Indians Make When Filing ITR

• Filing in the wrong ITR form: Especially salaried employees with ELSS redemptions filing ITR-1 instead of ITR-2. This results in a defective return notice.
• Not reconciling Form 26AS and AIS with Form 16: If there is a mismatch, file as per 26AS/AIS — these are what the department's system will verify against.
• Forgetting to report savings account interest: Banks report this to the department, and it appears in AIS. Many people assume it is tax-free — it is taxable above ₹10,000 (non-seniors) or ₹50,000 (seniors).
• Reporting only annual FD interest, not accrual-basis interest: FD interest is taxable on an accrual basis (as it accrues each year) even if you have not received it or if the FD has not matured. Failing to report this creates a mismatch with AIS.
• Not claiming all deductions under 80C: Many people forget to include EPF contributions (employee share), children's tuition fees, or home loan principal repayment in their 80C calculation.
• Forgetting to e-verify the return: A surprising number of people file but do not e-verify. An unverified ITR is legally as good as not filed. You have 30 days from the date of filing to e-verify.
• Not reporting previous employer's income: If you changed jobs, you must combine salary from both employers. Not doing so is treated as under-reporting of income.
• Choosing the wrong tax regime for their situation: Blindly selecting the new regime without calculating whether old regime saves more given your actual deductions and investments.
• Not reporting crypto or P2P lending income: The department has data from exchanges. Any virtual digital asset (VDA) income must be reported and taxed at 30% under Section 115BBH.

Real-Life Example: Filing ITR for AY 2026-27

Let us look at Priya Sharma, a 32-year-old software engineer working in Bengaluru for an IT company. Here is her financial profile for FY 2025-26:

• Gross salary: ₹14,00,000 per year
• HRA received: ₹3,00,000 (she pays rent of ₹25,000/month in Bengaluru)
• EPF contribution (employee): ₹60,000 (auto-deducted)
• LIC premium paid: ₹30,000
• ELSS SIP: ₹60,000 invested (no redemption)
• Health insurance premium: ₹20,000
• NPS Tier 1 contribution: ₹50,000 (80CCD(1B))
• Savings account interest: ₹12,000
• No capital gains

Under Old Tax Regime:

• Gross salary: ₹14,00,000
• Less: Standard deduction: ₹50,000
• Less: HRA exemption: ₹2,40,000 (calculated as min of HRA received ₹3L, 50% of basic salary ≈ ₹4L, actual rent minus 10% of basic ≈ ₹2.4L)
• Net salary income: ₹11,10,000
• Add: Other income (savings interest): ₹12,000
• Gross total income: ₹11,22,000
• Less: 80C (EPF ₹60K + LIC ₹30K + ELSS ₹60K = ₹1,50,000): ₹1,50,000
• Less: 80D (health insurance): ₹20,000
• Less: 80CCD(1B) — NPS: ₹50,000
• Less: 80TTA — savings interest: ₹10,000
• Taxable income: ₹8,92,000
• Tax: ₹5,000 (5% on ₹2.5L-5L) + ₹77,400 (20% on ₹5L-8.92L) = ~₹82,400 + cess
• Total tax: ~₹85,696 (including 4% cess)

Under New Tax Regime:

• Gross salary: ₹14,00,000
• Less: Standard deduction: ₹75,000
• Taxable income: ₹13,25,000
• Tax: Calculated at new slab rates = ~₹1,50,000 + cess = ~₹1,56,000

Verdict for Priya: Old Tax Regime saves her approximately ₹70,000 in taxes. She should file ITR-1 (no capital gains, single property, income under ₹50L) and opt for the Old Tax Regime. Documents she needs: Form 16 from employer, PPF statement, ELSS fund statement, LIC premium receipt, health insurance receipt, NPS statement, rent receipts with landlord PAN, home loan certificate (if any), Form 26AS, AIS.

Penalty and Consequences of Late Filing

Under Section 234F, if you file your ITR after July 31, 2026 (the due date for AY 2026-27):

• Late fee of ₹5,000 if total income exceeds ₹5,00,000
• Late fee of ₹1,000 if total income is between ₹2,50,001 and ₹5,00,000
• No fee if total income is below the basic exemption limit
• Last date for belated return: December 31, 2026 (after that, you cannot file at all unless the department allows it with special permission)
• Interest under Section 234A: 1% per month on tax due from the original due date if you have tax payable and file late
• Loss carry-forward forfeited: Capital losses, business losses cannot be carried forward if you file a belated return

Tips for a Smooth ITR Filing Experience

1. Start collecting documents in May itself: Form 16 comes by June 15. AIS and 26AS are available anytime. Do not wait for July — start preparation in May/June.
2. Always download and review AIS before filing: The AIS has information reported by banks, brokers, property registrars, and others. Any income in AIS that you do not report will trigger a notice.
3. Use a tax computation worksheet: Calculate your tax under both regimes before selecting. Even a ₹10,000 saving is worth 15 minutes of calculation.
4. Pre-validate your bank account: If your bank account is not pre-validated on the IT portal, your refund will not be processed. Go to My Profile → Bank Account on incometax.gov.in.
5. Keep proofs for 7 years: The Income Tax Department can scrutinise your return for up to 6 years (10 years in case of significant tax evasion). Keep all investment proofs, receipts, and documents for at least 7 years.
6. Avoid filing in the last week of July: The Income Tax portal experiences severe slowdowns and crashes in the final days before the deadline. File by July 20 to avoid technical issues.
