Why ITR preparation should start with records
Income tax return filing is easier when income records, tax deduction proofs, bank interest, AIS/TIS details and previous return information are reviewed before selecting the ITR form. Many filing errors occur because only Form 16 is checked while interest income, other income, capital gains, business receipts or TDS entries are ignored. A clean filing checklist reduces mismatch notices and helps the taxpayer understand whether any tax payment, refund claim or disclosure needs attention.
Salary and Form 16 review
Salary taxpayers should keep Form 16, salary slips, employer details and tax deduction information ready. If the taxpayer changed jobs, Form 16 from each employer should be collected. The gross salary, allowances, deductions, professional tax and TDS should be checked with AIS and Form 26AS. When Form 16 and AIS figures differ, the difference should be understood before filing so the return does not carry an avoidable mismatch.
Other income and bank records
Income tax return filing must consider savings bank interest, fixed deposit interest, recurring deposit interest, rental income, dividend income and other receipts where applicable. Bank statements help identify interest entries and cash flows that may not appear clearly in Form 16. For business owners and professionals, receipts, expenses, GST data, books of accounts and loan interest details may also be relevant. The checklist should cover all income, not only salary income.
Deductions and investment proofs
Common deduction proofs include LIC, PF, PPF, ELSS, health insurance, education loan interest, home loan interest, donation receipts and rent payment support where applicable. The taxpayer should not claim deductions only because they appear familiar; each claim should be supported by payment proof and eligibility. Incorrect deduction claims can create problems if the return is later verified or selected for review.
AIS, TIS and Form 26AS matching
AIS and TIS show information reported by banks, employers, deductors and other reporting entities. Form 26AS shows tax credit and TDS information. Before filing, the taxpayer should compare reported income, TDS, advance tax, self-assessment tax and refund status. If incorrect information appears in AIS, it may need feedback or explanation. Filing without reviewing AIS can lead to mismatch between the return and department records.
After filing the return
After the ITR is filed, acknowledgement and e-verification should be completed within the allowed timeline. The taxpayer should save the ITR-V, computation, acknowledgement, payment challan and supporting documents. Refund status, defective-return notices or intimation under section 143(1) should be monitored. Filing is not complete until the return is verified and the taxpayer understands the final status.
