Starting January 1, 2026, new financial regulations and tax provisions will impact individuals and entities. Key changes include mandatory PAN-Aadhaar linking; unlinked PANs will become inoperative, affecting tax filings and transactions. Failure to link may result in higher Tax Deducted at Source (TDS) and Tax Collected at Source (TCS) rates. Standard deductions for salaried individuals and pensioners have also been updated for the tax year beginning April 1, 2026, alongside revised thresholds for TDS/TCS.
