What Are Income Tax Refund Delays?

Income tax refund delays refer to the prolonged waiting period many taxpayers are experiencing before getting refunds owed after filing their Income Tax Returns (ITRs). In the current assessment year (AY 2025–26), a significant number of refund claims remain unprocessed, causing frustration across social media and grievance portals.

For many taxpayers who filed accurately and timely, refunds that used to arrive within weeks are now taking months. Experts say this year’s delays stem from an unprecedented combination of compliance checks, data verification enhancements, and legislative processing timelines that the tax department can legally use.

Key Causes of Processing Backlogs

1. Stricter Data Verification and Analytics

Income tax authorities are increasingly using data analytics and cross-checks against sources, for example, Form 26AS and the Annual Information Statement (AIS). Mismatches between filed return data and third-party reports trigger additional scrutiny before refunds are released.

2. “Nudge” and Compliance Campaigns

The CBDT’s NUDGE campaign encourages taxpayers to correct discrepancies or file revised returns proactively. While this improves long-term compliance, it slows down immediate refund issuance when returns are flagged.

3. Unprocessed Returns Backlog

As of early January 2026, tens of lakhs of ITRs remain unprocessed, with the department legally allowed up to December 31, 2026, to complete processing under Section 143(1). That backlog alone significantly delays refunds.

4. Missing or Incorrect Verification

ITRs not e-verified within 30 days of filing are treated as incomplete, halting refund processing until verification is completed. Bank account mismatches or unvalidated PAN-bank linkages can also delay refunds.

5. Bank Account and PAN-Aadhaar Issues

Refunds can’t be credited if a taxpayer’s bank account isn’t pre-validated on the income-tax portal or if PAN–Aadhaar linkage details don’t match.

6. High-Value or Complex Returns

Large refunds, foreign income claims, or complex deductions often trigger extra checks that extend processing time compared with simple salary-only refunds.

7. Late ITR Form Releases and Processing Timelines

The late release of ITR forms in 2025 pushed filing dates back, contributing to bottlenecks in processing and refund issuance.

Impact on Taxpayers and Interest Rules

Many taxpayers rely on refunds for personal expenses, savings, or cash flow planning. With these delays extending months—and in some rare cases, years—financial planning has been disrupted.

Under Section 244A of the Income-tax Act, taxpayers can receive 0.5% monthly interest on delayed refunds, provided the refund amounts to at least 10% of the total tax paid and the delay is not caused by errors such as incorrect details or mismatches on the taxpayer’s part.

Notable Cases Spotlighting Delays

In a high-profile case, the Delhi High Court slammed the Income Tax Department for an 8-year delay in processing a refund owed to a corporate taxpayer and warned of personal costs for decision-makers if the issue wasn’t resolved quickly—showing judicial concern over prolonged delays.

What Taxpayers Can Do

✔ Track refund online: Enter the details of your PAN on the Income Tax Department’s e-filing portal.

✔ Verify ITR properly: Ensure e-verification and accurate bank details.

✔ Resolve mismatches: Respond quickly to notices or flagged discrepancies in Form 26AS/AIS.

✔ Respond to communications: Updating or revising returns can clear blocks faster.

Is This the New Normal?

Some experts suggest this processing pace may be a temporary result of updated compliance strategies and post-deadline filing patterns. Others say the procedural changes could extend beyond a single year as tax authorities balance accuracy with speed.
