@SoniaEchols90 Do you know if there are known issues with the April tax update regarding the US federal income tax withholding calculations. We’ve seen some employees withholdings change incorrectly after applying the tax update.

I just had the same thing reported.  Client has salaried employees so taxable wages and and FIT are very consistent.  They just performed Tax Maintenance and FIT tax dropped significantly.  What is going on with the Tax Maintenance?

Paychecks with different withholding amounts are:

– Ref # 1509 – Previous FIT WH: $103.84 – New FIT WH: $131.54

– Ref # 1508 – Previous FIT WH: $405.52 – New FIT WH: $277.59

 – Ref # 1510 – Previous FIT WH: $717.35 – New FIT WH: $549.56

 – Ref # 1511 – Previous FIT WH: $275.36 – New FIT WH: $318.36
