If your lessee has deducted TDS from your lease rent but failed to remit it to the tax department for a specific month, you have recourse. Even if your Income Tax Return (ITR) was processed without accounting for that month's TDS, you can still claim it back. It's advisable to write to the lessee company formally, requesting they pay the deducted TDS. You can also lodge a formal complaint with the company to resolve the issue and ensure you receive the tax amount.
