Hot to change the master data in Google Sheet

I have a table with an overview of the calculation of some income-related taxes
Now all tax percentages are set for a specific year
I want to create a list of master data: the percentages per tax year

and then I have a drop-down list where I can select the tax year
To switch the master data, the tax percentages and parentheses to the percentages of the year (for the complete sheet)
