Before and After Filing IT Returns: 7 Checks That Matter

According to recent IT Department data, <cite index="2-1">over 4 crore income tax returns have been filed for Assessment Year 2026-27, with the department urging taxpayers to file before the July 31 deadline to avoid last-minute stress</cite>. But filing isn't just about meeting the deadline—it's about filing correctly. Missing even one check can result in refund delays or claim rejection.

Here are 7 essential checks before and after filing your IT return.

Key Takeaways

• Over 4 crore IT returns filed for AY 2026-27; July 31 deadline requires urgent action

• Pre-filing checks prevent claim rejections and ensure accurate income reporting

• Post-filing verification catches errors before IT department notices discrepancies

• Investment documentation is critical—keep receipts for all equity, mutual funds, and insurance

• Tax refunds process faster (28 days avg.) when filing contains no errors

• Seven essential checks cover income sources, investments, deductions, and compliance

• Missing investment proof can lead to rejection of investment-linked tax benefits

Check 1: Validate All Income Sources (Before Filing)

• What to Verify

Before your CA submits your return:

•  Salary income: Verify Form 16 details match your bank deposits

•  Investment income: Dividend statements, interest earned, rental income

•  Business income: Complete reconciliation with bank statements

•  Freelance/consulting income: Invoice totals match income declared

•  Gift income: If received, verify whether taxable (above ₹50,000 from non-relatives)

•  Other income: Bonuses, commissions, capital gains

Why it matters: Income mismatch between Form 16 and return invites IT scrutiny. The I-T Department's improved grievance redressal system resolves complaints faster, but prevention is better than cure.

Check 2: Document All Investment Proofs (Before & After)

Investment Categories Requiring Documentation

This is critical because many investment plan deductions depend on proof:

1.Equity & Mutual Funds:

• Proof of purchase (contract note, fund statement)

• Proof of investment value (latest NAV statement)

• Essential if investing through Money Back Policy or other insurance-linked investments

2.Fixed Deposits/Bonds:

• Receipt showing investment amount and date

• Interest earned (from Form 16A)

• Certificate of deposit

3.Insurance Investments:

• Policy documents for insurance plans offering investment benefits

• Premium payment receipts

• Guaranteed Return Plans premium statements

• ULIP Plans transaction records (if applicable)

4.Pension Plans:

• NPS statements (if investing in Pension Plans)

• Proof of contribution and current value

• Annual account statements

5.Real Estate Investment:

• Property purchase agreement

• Stamp duty and registration documents

• Home loan statement (if claiming interest deduction)

Action: Create a folder with all investment receipts. Digital copies are acceptable, but originals should be retained for 5-7 years.

Check 3: Verify Deduction Claims (Before Filing)

Common Deductions and Required Proof

1.Section 80C (₹1.5 lakh limit):

• EPF contributions: Salary slip showing PF deduction

• Life insurance premiums: Policy document + payment receipts

• ULIP Plans contributions: Transaction statements

• Pension Plans investments: Contribution receipts

• Total claimed cannot exceed ₹1.5 lakh

2.Section 80D (Medical Insurance):

• Health insurance premium receipts

• Policy document showing coverage details

• Self + family coverage breakdown

3.Section 80E (Education Loan):

• Loan agreement with lender

• Interest payment receipt

• Educational institution enrollment proof

4.Section 80G (Charitable Donations):

• Donation receipts from 80G registered charities

• Only donations meeting criteria count

Common Error: Claiming the same investment under multiple heads (e.g., claiming ₹1 lakh for Section 80C when Section 80CCD already covered ₹50,000 from same investment).

Check 4: Reconcile Bank Statements (Before & After)

Why Bank Reconciliation Matters

The I-T Department cross-checks bank deposits against declared income. Mismatches trigger notices.

Before Filing:

•  All salary deposits match Form 16 amount

•  Investment outflows (mutual funds, insurance) are documented

•  Large cash deposits are explained (source proof required)

•  International remittances match foreign income declared

After Filing:

•  Monitor bank account for unusual IT Department notices

•  Keep statements for reference if questioned

•  Respond immediately to any deposit-related inquiries

Reality Check: If you deposited ₹10 lakhs in July but declared only ₹8 lakhs income, IT Department will ask for source proof. Having it ready prevents notices.

Check 5: Review Investment-Linked Tax Benefits (Before Filing)

Common Investment Mistakes

Mistake 1: Not Claiming Available Deductions

• Many salaried employees don't claim Guaranteed Return Plans or Money Back Policy premiums

• These qualify for Section 80C deductions (₹50,000-₹1.5 lakh)

• Missing this means overpaying tax

Mistake 2: Mixing Up Plan Types

• Pension Plans qualify for Section 80CCD (separate ₹2 lakh limit)

• ULIP Plans might qualify for Section 80C or capital gains treatment (depending on structure)

• Confusion results in incorrect claim

Mistake 3: Not Tracking Guaranteed Return Plans

• Interest earned qualifies as income

• Often overlooked in income calculation

• Results in undeclared income

Before Filing: Collate all investment statements. Ask your CA to list which investments qualify for which sections.

Check 6: Validate Tax-Saving Investment Timing (Before Filing)

Critical Investment Dates

Investments made after March 31 of the assessment year don't qualify for current-year deduction:

For AY 2026-27 (April 2026-March 2027):

•  Insurance premiums paid on or before March 31, 2027

•  Mutual fund investments made on or before March 31, 2027

•  NPS/Pension Plans contributions made before March 31, 2027

•  Fixed deposits opened before March 31, 2027

Common Pitfall: Many investors invest in April thinking it counts for the previous year. It doesn't. Always calendar-mark investment deadlines.

Check 7: Cross-Check Computed Tax vs. Paid Tax (Before & After)

Refund vs. Additional Tax

Before Filing:

• Calculate expected refund (if any)

• Verify no additional tax liability

• Confirm all TDS credits are reflected

After Filing:

• Monitor for refund status (average 28 days per IT Dept)

• If notice received for additional tax, respond promptly

• Review any penalties or interest assessed
