All MIT postdoctoral associates (PDAs) and postdoctoral fellows (PDFs) are paid semimonthly on the 15th of the month and on the last day of the month. If either falls on a weekend or holiday, the pay date will be the business day that precedes that weekend or holiday. PDAs are taxed as employees and are subject to the same taxes—federal and state income, Social Security, and Medicare (FICA). MIT is required to withhold taxes from PDA payments.
PDAs must submit the appropriate withholding forms using the “Tax Withholding” page of the “My Money” section of the Atlas website. Use the Financial Information for Postdoctoral Fellows and Associates sheet to advise your PDAs about MIT’s payroll and tax procedures for associate appointments.
PDFs are subject to federal and state income taxes but not Social Security or Medicare (FICA) taxes. Depending on the funding source, MIT may not be allowed to withhold taxes from a fellowship stipend. Use the Financial Information for Postdoctoral Fellows and Associates sheet to understand the requirements and restrictions that apply to your PDFs.
When you change an appointee from a postdoctoral associate to a post-doctoral fellowship or from a postdoctoral fellowship to a postdoctoral associate, you may change the appointee’s tax liabilities and benefits eligibility. Use the Impact of Switching from PDA to PDF Appointment (or Vice Versa) sheet to assess the impact on your DLC’s appointee(s).
If you are making a late/retroactive appointment change, email VPF’s HR/Payroll team or call 617-253-4255.
