US FEDERAL TAX CALCULATION#

This document describes the US Federal Tax Calculation using the Symmetry Tax Engine (STE) Software.

Federal Tax Calculation#

General Set Up UDGNIS
This is the process to load all US Tax jurisdictions into IDCO, IDSP, IDCN, IDCI, IDMN, IDSD, IDZR, and IDTX.

UPUTR
This is the process to load all US Tax Rates and States Miscellaneous parameters.
After UPUTR is run, the applicable Tax Rates and Miscellaneous Parameters can be viewed by State in IPUTR and IPUTP.

IPUTR
US Tax Rates can be viewed by State and the Overridden Rates and Wage Base entered.
Some SUTA surcharge calculations for specific states can be suppressed by checking the 'Do not Calculate' toggle.

IPUTP
The US Tax Miscellaneous parameters can be be viewed by the States that are applicable for IPRLU.

IDGV
This form can optionally contain specific override rates and Wage Bases by Government Registration for each registration from the pay header's group. IDGV overridden amounts take precedence over the IPUTR overridden amounts.

IPPC
Pay components must be set up with applicable IPCU PC Usages for US taxation.

IDTX Applicable Tax Jurisdictions that are paid by employees are entered here. On the IPPH/IEPI, IEAS, IDLN, etc. forms that require a tax jurisdiction, the 'Tax Jurisdiction Editor Utility' dialog box can be used to enter the jurisdiction on IDTX.

IPRLU/IPRLUS
Each employee must be set up with the applicable tax methods. Miscellaneous Tax parameters must be set up by the states that need to be paid.

UPRLU
This process audits the US Tax Filing Information and generates IPRLU Miscellaneous Tax Parameters information according to IMCT set up.

IPPH

• The 'Pay Header' tab must define the default Work and Home jurisdictions.
• The 'Pay Lines' tab, 'Jurisdiction' field must define the Work Jurisdiction of this pay line.
• After the Trial Calc or UPCALC, the 'Pay Amounts' tab contains all US Taxation amounts, in summary, that are used for the calculation of net pay.
• The 'Pay Jurisdiction' tab contains the default Work and Home jurisdictions.
• After Trial Calc or UPCALC, the 'Pay Jurisdiction' tab contains all US Taxation amounts, by jurisdictions, in detail.
  
  

IPUTP - Federal Tax Parameters#

When UPUTR is run, it loads in a list of federal tax parameters for Symmetry Federal Tax calculation.

On IPUTP, the following Federal tax parameters are available to be used on the IPRLU/IPRLUS forms:

• IRS_MAX_EXEMPTIONS
• APPLY_BENEFIT_WAGE_LIMIT

These parameters will not automatically be added to IPRLU/IPRLUS by the UPRLU process for all employees. IPRLU/IPRLUS information is required to be manually added for employees who are eligible for each parameter.

IRS_MAX_EXEMPTIONS

• IRS maximum number of exemptions allowed. Optional, numeric
• Allows an employer to define on the employee's IPRLU/IPRLUS form the maximum number of exemptions allowed for this employee as indicated by the IRS in a 'lock-in-letter'.
• UPCALC will cap the employee's 'Federal # of Exemptions' with the value from IPRLU/IPRLUS 'IRS_MAX_EXEMPTIONS' parameter.
• Any number provided will override the 'Federal # of Exemptions', including 0.
• Do not provide a default value

APPLY_BENEFIT_WAGE_LIMIT

• Optional, alphanumeric
• Allows a user to specify if the Benefit Annual Wage Limit should be applied by the SymmetryTaxEngine when an employee’s wages reach the $250 000 limit. By applying the limit, when an employee reaches the limit (Regular and Supplemental wages combined), the employee’s 401k / 457 deductions become taxable. By not applying the annual limit, when an Employee reaches this annual wage the deductions are not taxable for Federal. This is typically used when an employee’s Supplemental wages should Not be considered in the annual wage equation.

IPUTR - Federal Tax Rates#

When UPUTR is run, it loads in a list of Federal Tax rates for the Symmetry Federal tax calculation.

• On IPUTR, when the State is defined as 'Federal' the Federal Tax Rates can be viewed.
• Each Tax Identifier can provide the default Tax Rates and Wage Base to be used for Federal tax calculation.

IMPORTANT: For the ER_FUTA identifier, users MUST enter their own Employer FUTA rate (provided by the government) on the 'Override Tax Rate' field. Symmetry requires this FUTA Rate to be passed into the Symmetry Tax Engine, otherwise ER FUTA will not be calculated.

IPRLU - US Tax Filing Information#

Both IPRLU and IPRLUS can be used to maintain US Tax Filing Information for an employee.
IPRLU contains all US Tax Filing Information for both Vertex and Symmetry Tax users.
IPRLUS contains the US Tax Filing Information for Symmetry Tax users only:

• The Federal, State and Local tabs must define all tax methods and eligibility information.
  

• For Federal Tax Calculation, the '# of Exemptions' must be entered on the Federal tab, if an employee has an IRS letter that indicates the maximum number of exemptions allowed. Then, on either the Miscellaneous tab or the State tab, the IRS_MAX_EXEMPTIONS Misc. Identifier must be defined.

7928	Pre-FWT HSA Exemption -Suppl Tax (PPE)
7801 to	Pre-Reg Custom Benefit 01 - Reg Tax (PPE)
7830	Pre-Sup Custom Benefit 10 - Suppl Tax (PPE)

PC Usage - Federal Insurance Contribution Act (FICA) Tax#

Federal Insurance Contributions Act Tax (FICA) is imposed by the federal government on both employees and employers. The FICA tax is calculated using Pay Component Usages 6201 - 6261.

Usage	Description
6201	FICA Employee Deduction
6202	FICA Employee Earnings
6210	FICA Employer Contribution
6211	FICA Employer Earnings
6251	Pre-FICA Employee Earnings (PPE)
6261	Pre-FICA Employer Earnings (PPE)

PC Usage - Medicare Tax#

Medicare Tax is an employer and employee paid tax. The Medicare tax is calculated using Pay Component Usages 6501 - 6552.

Usage	Description
6501	Medicare Employee Deduction
6502	Medicare Employee Earnings
6503	Medicare Employer Contribution
6504	Medicare Employer Earnings
6551	Pre- Medicare Employee Earnings (PPE)
6552	Pre- Medicare Employer Earnings (PPE)

PC Usage - Federal Unemployment Tax Act (FUTA)#

Federal Unemployment Tax Act (FUTA) is an employer paid tax. The FUTA tax is calculated using Pay Component Usages 6401 - 6451.

Usage	Description
6401	FUTA Employer Contribution
6402	FUTA Employer Earnings
6451	Pre-FUTA Employer Earnings (PPE)

There are two ways of providing the FUTA tax rate:

1. IPUTR
   • Enter the rate or wage base provided by the government on the Override fields
   • These overrides are applicable for the entire company for the federal calculations
2. IDGV
   • If there is a specific rate provided by the government for a different Registration #, update the 'Reg Type' field on IDGV. This overrides the IPUTR Rate.
   • UPCALC retrieves IDGV by Government Registration from the employee's Pay Header group

If you do business in a State that has been given a FUTA Tax Credit reduction, the new FUTA tax rate for that specific State can be entered on IDGV for the State. In IDGV, add a new entry for the specific State, define the Registration Type as 'US SUI Regist 1', and define the Govt Rate Type as 'US FUTA Rate'. This State specific FUTA rate will be picked up by the UPCALC program when an employee is being paid in that State.

PC Usage - Railroad Taxation#

Railroad taxation is calculated using Pay Component Usages 6301 - 6356.

Federal Tax Calculation#

UPCALC Example - Federal Withholdings #

US Federal Tax Calculation_01.JPG

IPRLU Federal Filing Status:	= Single
Regular Earnings:	= 1923.08
Supplemental Earnings:	= 100.00

Pre-Tax Benefits:

125 Plan	145.89
401K Plan	+ 112.54
403B Plan	+ 20.84
457 Plan	+ 16.18
Simple IRA Plan	+ 14.97
Total	= 310.42

Prorate Pre-Tax Benefits to Regular and Supplemental Earnings:

Reg Earn Pre-Tax Benefit	= 1923.08 / 2023.08 * 310.42	= 295.08
Sup Earn Pre-Tax Benefit	= 100 / 2023.08 * 310.42	= 15.34

FIT Withholding:

PC 8005 FIT Earn	= 1923.08 - 295.08	= 1628.00
PC 8015 FSP Earn	= 100.00 - 15.34	= 84.66
PC 6000 FIT Tax	= Based on PC 8005 $1628.00	= 237.77
PC 6010 FSP Tax	= Based on PC 8015 $84.66 x 25%	= 21.17

FICA / MEDICARE#

FICA Wage < FIT Wage Example#

US Federal Tax Calculation_02.JPG

When an Employee works for Regular Employment and Railroad Employment, FICA YTD and RRTA YTD are both used in the FICA calculation.

FIT_Wages	Usage 6051 Pre FWT Earnings	6676.24
FICA_Wages	Usage 6261 Pre-FICA Employer Earnings	6596.13

PC 8005 FIT Earn	= FIT_Wages - 125 - 401K	= 6676.24 - 200.33 - 239.57	= 6236.34
PC 8039 FICA ER Earn	= FICA_Wages - 125	= 6596.13 - 200.33	= 6395.80

FICA ER - No Self Adjust Method

PC 7030 Medicare ER	= Med ER Earn x 0.0145	= 6395.80 x 0.0145	= 92.74

FICA ER - Self Adjust Method
This employee uses the 'Self-Adjust Method'.

FIT_Wages.ctd	Usage 6051 Pre FWT Earnings	= 6676.24
FIT_Wages.ytd	Usage 6051 Pre FWT Earnings	= 51747.29

For Railroad Taxation, if an employee has FICA contribution during the year, this means the employee works between the Railroad and Non-Railroad Assignments. In this case, please check if the 'RR Self-Adjust' method should be used for this employee or not.

The reason is, if 'RR Self-Adjust' method is defined on IPRLU, this method is applicable for both RR Tier1 and Tier2 calculations. However, since Regular FICA does not have a Tier2 calculation, the 'RR Self-Adjust' method will automatically re-adjust all earnings that include YTD FICA Earnings that are not subject to Tier2 calculation. This would cause the entire YTD Earnings to subject to Tier2 tax.

Since employees should only pay Tier2 tax for the earnings that are earned for Railroad employment, if employee has FICA contribution, it should be verified if this employee should use the 'Self-Adjust' method to re-calculate all Tier2 tax or just use 'RR No Self-Adjust' method.

The next example shows the 'RR Self-Adjust' method and should be used when the employee does not have FICA employment.

RRTA - Self Adjust Method

FIT_Wages.ctd	Usage 6051 Pre FWT Earnings	= 6153.82

RRTA_Wages.ytd	Usage 6306 Pre-Tier1 Soc ER Earn	= 57654.05

If RRTA Earnings (RRTA_Wages.ctd) is different than FIT Earnings (FIT_Wages.ctd), then calculate the difference between the wages for RRTA and FIT (such as Usage 6306 - Usage 6051). This is called Additional RRTA Wages.
