Increment one year for each row in given group.

I have a query were I need to increment by one year for each row within an employee group. So for each row for a given employee I need to add one year and restart on the next employee group.

I have:
EmployeeNo, EligibilityDate
001, HireDate
001, HireDate
001, HireDate
002, HireDate
002, HireDate

What I am looking to accomplish is:
EmployeeNo, EligibilityDate
001, DateAdd(yy, +1, HireDate)
001, DateAdd(yy, +2, HireDate)
001, DateAdd(yy, +3, HireDate)
002, DateAdd(yy, +1, HireDate)
002, DateAdd(yy, +2, HireDate)

Any suggestions on how I may be able to complete this would be greatly appreciated!

		(CASE WHEN AnnualSurvey_DateCompleted.DateCompleted IS NOT NULL THEN LEFT(CONVERT(VARCHAR(10), adj_hire_date, 101), 5) + '/' + CONVERT(VARCHAR(4), YEAR(AnnualSurvey_DateCompleted.DateCompleted)) ELSE CONVERT(VARCHAR(10), DATEADD(yy, +1, adj_hire_date), 101) END) AS EligibilityDate,
		AnnualSurvey_EmailDate.EmailDate AS EmailDate,
		AnnualSurvey_DateCompleted.DateCompleted
