State tax filing

"But the credit cannot be more than the MI tax calculates on the Toledo income,"   This is the part I don't understand.  And the example shown in the booklet shows different amounts of income being earned in different states.  In my case 100% of income is earned in Toledo OH (but I live in MI).  So because of the reciprocal agreement  I don't pay any (payroll) state tax to OH, I pay it to MI.  But I pay (payroll) City of Toledo 2.25% tax from my wages and this amount is listed on the W-2.  

 

In a nutshell, the Mi tax rate is 4.25%.  So if line 17 equals $3650 and line 18 equals $2000, line 18a and 18b would also be $2000.  $3650 - $2000 = $1650.  So the MI tax owed would be $1650?
