Internet TAXSIM Special for Wilhelm
Internet TAXSIM
Version 8.0
TAXSIM is the NBER's FORTRAN program for calculating liabilities under US Federal and State income tax laws from individual data. Scholars interested in using TAXSIM to calculate tax liabilities and marginal tax rates should follow the these instructions for submitting data. Liabilities are returned as an online web page in a few seconds. The program itself is not released.
There is Stata interface to TAXSIM allowing tax calculations to be made without leaving the Stata environment. The calculations themselves are done here at the NBER, using the tax calculator described below. More information is available from within Stata via the commands:
There is also documentation for a raw TCP/IP interface using Netcat. This makes possible lower level access to the tax calculator for users integrating TAXSIM into other statistical packages or automated systems.
Version 8.0 introduces:
- Federal taxes 1960=2013 (as of May 2006,including TIPRA)
- State taxes through 2006.
- Sales tax deduction.
- Netcat interface for large datasets.
- Minor corrections noted in change log.
Further changes will be noted in a change log .
