It's my understanding that installing the new tax tables does not affect the W2 printing with Aatrix.  

Here's a similar post that was recently answered sagecity.na.sage.com/.../81164.aspx

It still seems very unclear and the install program instructs you that they must be installed after W2 and before first 2015 PR

Sorry about any confusion that has been caused, nothing has changed regarding the way tax tables affect the Payroll module.

The tax table update rates and limits will not affect amounts that print on W2s BUT they will affect amounts on Payroll reports (i.e. Quarterly Tax Report, Quarterly Governmental Report). If you change your State Unemployment rate to reflect your 2015 tax rate that new 2015 tax rate will pull into applicable  eFIling forms and will need to manually be changed to your 2014 UI tax rate when printing 2014 forms (if applicable).

The recommended way is to print 2014 W2s before installing the 2015-Q1 TTU and processing 2015 payroll.

If that is not possible because of pay cycle ending dates then the recommended way would be the same as it has always been:

1. Install the 2014 IRD (**this step does not need to be done first, but the 2014 IRD must be installed before processing 2014 W2s)
2. Print applicable Payroll reports (i.e. Quarterly Tax Report, Quarterly Governmental Report) 
3. Verify Years to Retain eFiling History is set appropriately and verify Retain Perpetual History is selected in Payroll Options
4. Make a copy company (**this company code will be used if you dont have time to print quarterly reports before closing year end or if any adjustments need to be entered for payroll dated in 2014).
5. In Live Company Code, close the year using Period End Processing
6. After Year-end Processing is completed, install the latest Tax Table Update (2015-Q1 TTU) and verify the accuracy of your state(s)unemployment Tax Rates for each company in Tax Table Maintenance before processing the next quarter’s Payroll.
7. Process 2015 Payroll
8. After reconciling QTD & YTD amounts and ready to print 2014 W2s, install the 2014-Q3 TTU and change the State(s) UI to reflect the 2014 UI tax rate.
9. Print the 2014 W2/W3, 941 and 940 forms and verify accuracy
10. Install 2015-Q1 TTU and verify State(s) UI rate reflect your 2015 UI tax rate
