B-tax, a new model made available within the suite of tax models developed by the OSPC, allows users to calculate EMTRs on new investment under federal tax law and to specify alternatives to calculate changes in EMTRs.
The OSPC modeling suite does not yet offer the ability to produce a revenue estimate from changes to the corporate income tax, but it is worth noting that JCT revenue estimates for similar changes are quite large.
More information about tax calculator, the model employed to analyze the reform plan, and the OSPC generally can be found at www.
Details about the B-tax model can be found on OSPC GitHub repository at https://github.
Specifically, each taxpayer in the OSPC database is ranked based on their adjusted gross income and then assigned to one of 100 buckets or percentiles.
5) According to OSPC, the model "relies on a micro dataset that closely reproduces the multivariate distribution of income, deduction and credit items in 2009, extrapolated to 2015-2024 levels in accordance with CBO forecasts available in Spring 2015.
8) In the future, OSPC intends to extend the complexity of the OG-USA model to incorporate more household heterogeneity, realistic population dynamics, and estimated effective and marginal tax rate functions that depend on both capital and labor income.
