This issue occured only when Ohio residents worked in a Kentucky location where
either of the following conditions existed for a county tax:

• The county tax had a maximum limit.
• The county tax was eliminated when a city tax existed.
  Previously, in some instances, PTQ was not correctly deducting the work tax
  credit during the calculation of the resident tax for cities in Ohio.
  
  This issue was addressed, effective with this release. 
  
  The calculation was modified to calculate the correct credit amount.
  

This issue affects only employees who live and work in the same city in Ohio, and
who are exempt from the city tax.
If an employee lives and works in the same Ohio city and is tax exempt, PTQ was
returning the subject gross wages on the resident tax handle in error. 

This issue was fixed.

Before this release, there were some calculation issues when an override tax or
override rate was passed, or when an additional supplement tax or rate was
passed. These issues occurred in Canadian Federal and Quebec Provincial tax
calculations.

The following calculation methods were affected:

• Concurrent Aggregation
• Annualized Concurrent Aggregation (Federal only)
  
  These issues were fixed.

The Medicare and Railroad Retirement Tier 1 (Medicare portion) tax rate is
currently 1.45% each for the employee and employer. In addition, you must
withhold 0.9% Additional Medicare Tax from wages that you pay to an employee
in excess of $200,000 in a calendar year. Employers are required to begin
withholding Additional Medicare Tax in the pay period in which they pay wages
in excess of $200,000 to an employee and continue to withhold it each pay
period until the end of the calendar year. Additional Medicare Tax is imposed
only on the employee. There is no employer share of Additional Medicare Tax.
When corporate acquisitions meet certain requirements, wages paid by the
predecessor employer are to be treated as if they were paid by the successor
employer for purposes of determining if the employee has reached the
Additional Medicare Tax or Railroad Retirement Tier 1 Tax (Medicare portion)
withholding threshold.

Vertex Payroll Tax Q Series Enhanced Integration
Summary of Program Modifications
March 2017 3

What these changes mean:
For PTQ to use year-to-date wages to accumulate the wages for both employers,
you must pass the predecessor employer wages and taxes in the following fields:

• eVprtGrsIDPriorState - Prior State Gross
• eVprtGrsIDPriorStateSup - Prior State Supplemental Gross
• eVprtTaxAmtIDPriorState - Prior State Tax Amount
• eVprtTaxAmtIDPriorStateSup - Prior State Supplemental Tax Amount PTQ will add the information in these fields for predecessor employer wages  year-to-date

Currently, PTQ calculates the territorial income tax for the Virgin Islands (VI). The
Virgin Islands calculation does not handle multi-work situations. If the work and
resident locations are not in the same territory, the calculation status is set to
Invalid Employee handle, and no taxes are returned.

Beginning with this release, VI State Unemployment (SUI) calculates when the
work GeoCode is 78-000-0000 (VI) even if the resident GeoCode is not the same.

This calculation change is for VI SUI ER only.

The self-adjust and self-adjust at maximum calculation methods are complicated
if a portion of the employee's year-to-date earnings are earned in Quebec, due to
the difference in the CPP and QPP contribution rates and annual contribution
limits.

To determine if the employee and employer have satisfied the annual maximum
contribution for the Canada Pension Plan (CPP) when the employee transfers
from Quebec to another province, enhancements were made to the
contributions calculations that use the self-adjust and self-adjust at maximum
calculation methods.

Beginning in 2017, the Maine Department of Revenue updated the formula for
calculating Maine withholding tax.

In release 4.2.2, Vertex modified the program code and updated the calculation
to account for these changes. Refer to the Vertex Payroll Tax Q Series Calculation
Guide for more information about the changes in calculations.
