Dynamic sheet reference in formula INDEX MATCH usinf INDIRECT

Hello

I am trying to make my INDEX MATCH formula dynamic for the sheet reference however I receive an error when I make the first MATCH argument INDIRECT("'"&B$2&"'!"&"$B$9:$AO$256"), dynamic using INDIRECT:

When I use the following formula, I receive the N/A error:

=INDEX(INDIRECT("'"&B$2&"'!"&"$B$9:$AO$256"),MATCH('Tax Analysis by Entity'!$C4,INDIRECT("'"&B$2&"'!"&"$B$9:$AO$256"),0),MATCH('Tax Analysis by Entity'!D$2,INDIRECT("'"&B$2&"'!"&"$B$8:$AO$8"),0))

When I remove the first INDIRECT argument from the first MATCH the formula returns the correct result however the first MATCH sheet reference argument is not dynamic:

=INDEX(INDIRECT("'"&B$2&"'!"&"$B$9:$AO$256"),MATCH('Tax Analysis by Entity'!$C4,'2018 Income Statement'!$B$9:$B$256,0),MATCH('Tax Analysis by Entity'!D$2,INDIRECT("'"&B$2&"'!"&"$B$8:$AO$8"),0))

Can somebody assist me to resolve this problem so that all sheet references are dynamic?

Please find attached a sample file. I have eliminated a lot of data so that it accurately reflects what I am trying to achieve.

Thank you in advance for your help.
