Tax refund entitlement preserved: statutory right maintained under new bill with procedural verification by Assessing Officer.
Clause 431 preserves a statutory right to a refund where a person satisfies the Assessing Officer that tax paid, paid on or treated as paid on their behalf for a tax year exceeds the amount properly chargeable; it covers direct payments and deemed payments (TDS/TCS, advance tax), places an initial procedural burden on the taxpayer, and mirrors Section 237 of the 1961 Act except for the shift from assessment year to tax year, with attendant implications for temporal reference, procedural integration, and ancillary issues such as interest, set offs and standards of verification.
