Payroll customer on Sage 4.5, still on maintenance. Only in one state with no income tax. About 30 employees and have already manually updated tax tables. What version do you upgrade them to? Do you go to 2015 and keep them off subscription for 1 more year, do you go to 2017 and avoid the change to new payroll, or do you bite the bullet and upgrade them all the way even though they do not need the functionality?
