Despite that delay, there are a few IRS changes you may see reflected in your January paycheck:

  • The OASDI (old age, survivors and disability insurance) tax will be withheld from income up to $128,400 in 2018. If you reached the maximum last year, your deductions will restart in January.
  • The Additional Medicare Tax will restart if your salaries and wages exceed $200,000 for 2018.
  • The annual deferral limit for 403(b) and 457(b) plans increased from $18,000 to $18,500.
