As of February 1, the BeyondPay system will utilize the latest 2018 tax withholding tables. This is an automatic updated that requires no setup.
All payrolls processed on or after February 1, 2018 will withhold the new tax rates.
The new withholding tables are designed to work with Form W-4 that workers have already filed to minimize the burden.
The IRS is revising Form W-4, but until the revised Form W-4 is made available (slated for 2019), employers should continue issuing the 2017 Form W-4. You may reassure your employees that they do not have to do anything at this time.
