DISCLAIMER This is in constant development to accommodate all filing statuses and tax situations. If there are errors, they will likely be for those who are not filing as single and those who have income/deductions/credits from sources other than an employer. Please double-check the work of these functions, DO NOT rely on these functions to file your taxes. The goal, however, is to eventually be able to rely on these functions to file taxes. Extensive tests are setup to check calculations, but errors are still possible due to misunderstanding of the tax code or negligence.
Conduct federal tax calculations with these tax-related functions. Federal income, Social Security, and Medicare tax functions are available.
