Duplicate primary key
I am new in database and ms access.I am developing a database of income tax return form submitted by several taxpayers. Where each tax payer has an unique ID called ETIN (electronic taxpayer identification number). so the database I am trying to develop contains more or less the following fields:
1.ETIN,2.Name.3.Father Name 4.Address 5.Gender 6. Assessment year 7.Shown income in return form 8.expense related to lifestyle 9.accretion of wealth
e.g.726226628279,Adam Smith,Joan Smith,3/4 jackson street,Male,2018-2019,2300000,800000,1500000
Now the problem is I cannot set ETIN (which is 12 digit unique numbers) as a primary key since after one year for a single ETIN there will be more than one entry for each assessment year and this will be duplicated triplicate quadruplicate and so on ..for the in coming years.
Now can any one guide me how to develop this simple database?
