However, before we get into the specific changes that have been implemented, it is important to note that Publication 15, the publication that explains employer's tax responsibilities, has yet to be released for 2018. With the tax reform bill that was signed into law in December, the IRS needs additional time to make changes to the withholding guidelines. The IRS has plans to release the guidelines in January for February implementation and have provided guidance to employers to use the 2017 Publication 15 release for the time being. Their official statement on the 2018 Publication 15 guidelines is below:

"We anticipate issuing the initial withholding guidance in January, and employers and payroll service providers will be encouraged to implement the changes in February. The IRS emphasizes this information will be designed to work with the existing Forms W-4 that employees have already filed, and no further action by taxpayers is needed at this time.  

Use of the new 2018 withholding guidelines will allow taxpayers to begin seeing the changes in their paychecks as early as February.  In the meantime, employers and payroll service providers should continue to use the existing 2017 withholding tables and systems."

Moving into the changes that have been implemented in the 2018 release of US Payroll for Odoo, check out our breakdown below.
