Key Features
The current release includes several new features which significantly enhance the functionality of the Equus Platform.
Domestic Cost Estimates: United States
Added support for the calculation of equalized cost estimates between two American states. A domestic cost estimate provides federal income and social taxes, along with home and host state income taxes. Where double taxation occurs, a credit is taken in the home state for taxes paid in the host state on assignment income.
New United States Tax Position
A new tax position, US Assignment Type, was added to designate cost estimates from the United States as either International or Domestic. This tax position defaults to International.
To calculate a domestic cost estimate:
United States must be the home and host tax estimator.
US Assignment Type must be set to Domestic on the United States home tax estimator.
Tax Calculation Method must be Equalization.
New Tax Position Set
The US Domestic Cost Estimate Tax Position Set is included with Equus Platform v.25.4. This tax position aids in configuring domestic cost estimates by hiding and locking any tax positions that will be ignored as part of the cost estimate.
