How useful is the computation code though? The computations themselves for the cells on a 1040 form are not that complicated and well documented in the instructions. The hard part is getting all the right numbers into the source boxes.
Somehow, the IRS compares the tax return I submit with what they expected. It is that entire machinery that is in the public interest to be visible and audited by the public.
The IRS does have income information, but they do not have deduction information. Deductions are mainly where any form of complexity comes in. Without deductions taxes are super easy.
Agreed, but one ought to be able to FOIA the entire pipeline that handles the data. This is especially so given that the results of the pipeline are used for tax enforcement and litigation.
