My current large corporate employer is changing my payroll EIN this month. I believe this will result in two W2 for my 2020 tax year in addition to creating excess social security tax withholding (Max $8240 x 2). Rather that waiting an expected refund after filing a year from now, seeking advice if it's appropriate to adjust my W2 to reduce my federal withholding tax to make up some of the difference. Thanks for the help.
