Income Tax Return (ITR) Filing Checklist: Comprehensive Preparation Guide
Step-by-step preparation checklist for individual and business ITR filings, covering New vs Old regime selection, AIS/26AS reconciliation, and documentation.
1. Essential Document Collection & Source Verification
Accurate direct tax return filing begins with collecting all relevant primary financial records and reconciling them against statutory data statements maintained by the Income Tax Department.
- Form 16 (Part A & Part B): Issued by employers detailing salary income, TDS deducted, and Chapter VI-A deductions.
- Form 26AS: Tax credit statement showing TDS from salaries, non-salary payments, TCS, and Advance Tax/Self-Assessment Tax payments.
- Annual Information Statement (AIS) & Taxpayer Information Summary (TIS): Comprehensive reporting of savings interest, dividends, securities transactions, and mutual fund trades.
- Capital Gains Statements: Summaries from stockbrokers and mutual fund depositories (CAMS/KFintech).
- Housing Loan & Interest Certificates: Showing principal repayment (Sec 80C) and interest paid (Sec 24(b)).
2. New Tax Regime (Section 115BAC) vs Old Tax Regime Analysis
Under the Finance Act, the New Tax Regime is the default tax regime for Individuals, HUFs, and AOPs. Taxpayers must perform a comparative tax computation before filing to determine which regime yields lower tax liability.
| Attribute | New Tax Regime (Default) | Old Tax Regime (Optional) |
|---|---|---|
| Tax Slabs & Rates | Concessional tax slabs with higher threshold limits | Traditional tax slabs with higher marginal rates |
| Standard Deduction (Salary) | Available (as applicable per statute) | Available (₹50,000 for salaried employees) |
| Chapter VI-A Deductions | Generally not allowed (except employer NPS Sec 80CCD(2)) | Allowed (80C, 80D, 80G, 80TTA/TTB, etc.) |
| House Property Loss (Self-Occupied) | Not allowable against salary/other income | Allowable up to ₹2,00,000 under Section 24(b) |
| Opt-out Form for Business Income | Form 10-IEA required before due date under Sec 139(1) | Not applicable if remaining in old regime |
3. Selecting the Correct ITR Form
Filing an incorrect ITR form makes the return defective under Section 139(9). Practitioners and taxpayers must verify income composition before submission.
- ITR-1 (Sahaj): Resident individuals with total income up to ₹50 lakh from Salary, one house property, and other sources (interest/dividend).
- ITR-2: Individuals and HUFs not having income from profits and gains of business or profession (capital gains, foreign assets, multiple house properties).
- ITR-3: Individuals and HUFs having income from profits and gains of business or profession (Proprietorships, audit cases, partners in firms).
- ITR-4 (Sugam): Resident individuals, HUFs, and firms (other than LLPs) opting for presumptive taxation under Sections 44AD, 44ADA, or 44AE.
4. E-Verification & Post-Filing Compliance
An Income Tax Return is not considered legally valid until it is verified within 30 days of submission. E-verification can be completed instantly using Aadhaar OTP, Net Banking, or Electronic Verification Code (EVC).

Frequently Asked Questions
What should I do if an interest amount in AIS is higher than my actual bank statement?
You can submit online feedback on the Income Tax e-Filing AIS portal flagging the transaction as incorrect or duplicate. In your ITR, report the correct actual interest earned and maintain supporting bank certificates.
Can an Income Tax Return be revised after filing?
Yes. Under Section 139(5), a revised return can be filed up to 3 months prior to the end of the relevant assessment year or before completion of assessment, whichever is earlier.
