Unclear.
Do you mean something like the following?
DECLARE @sql VARCHAR(MAX)
SET @sql = 'Declare @Tax as varchar ; Declare @address as Varchar ; select @Name=Name,@address=Address from Employee where empid=12 '
EXECUTE ( @sql )

Is it possibly because you do not have "@Name" declared (only @Tax - unused and @address) that you're having a problem?

yes

Declare @Name as varchar
Declare @address as Varchar
Exec('select @Name=Name,@address=Address from Employee where empid=12 ')

Use sp_executesql[^]:

SQL

DECLARE @Name as varchar(50);
DECLARE @Address as varchar(50);

EXEC sp_executesql 
    N'SELECT @Name = Name, @Address = Address FROM Employee WHERE empid = 12',
    N'@Name varchar(50) OUTPUT, @Address varchar(50) OUTPUT',
    @Name = @Name OUTPUT,
    @Address = @Address OUTPUT
;

How to specify output parameters when you use the sp_executesql stored procedure in SQL Server [^]
