How do I get a refund if more TDS was deducted than my actual tax?

File your income tax return and claim the TDS as credit. Tax deducted is matched against Form 26AS / AIS, and if the total TDS and advance tax paid is more than your actual tax liability, the excess is refunded after the return is processed.

Check that the deductor has filed the TDS return and that the amount shows in your Form 26AS, otherwise the credit may not be allowed. The refund is paid to your pre-validated bank account, and interest may be payable on delayed refunds as per the Income-tax Act. For your specific case, confirm with your CA or tax advisor.
