This discussion addresses a user's TDS mismatch issue for assessment year 22-23, which led to a tax demand notice. The user incorrectly entered the deductor's TAN number and found that online rectification and reprocess options were not suitable. Several users suggest offline rectification as the most effective solution, with some offering further personal assistance. The consensus is that revising the ITR or using offline rectification is necessary to correct the data and resolve the demand.
