I own three houses which are occupied by me and my family. Is there any tax implication for financial Year 2021-22?

Self-occupied property choice allows two homes to be treated as self-occupied; additional house is deemed let-out and taxed.

Tax treatment permits a taxpayer to designate two houses as self-occupied and requires any remaining house to be treated as deemed let-out, with the unselected property taxed accordingly; the taxpayer may choose which two properties are regarded as self-occupied and the remaining property will be assessed under the rules for let-out property.
