Anthracite Biztax

The corporate income tax return, importable as is.

What it does

  • Reserves broken down box by box, disallowed expenses account by account
  • Form 275U classified entry by entry, liquidation reserve, rental annex 270 MLH, embedded PDF annexes
  • The whole tax cascade, including the basket
  • Internal validators that replay the official arithmetic rules before producing the file
  • A deliberately blocked test file, identical to the real one down to the cent and guaranteed to be rejected, which hands you Biztax's full error report without filing anything
  • Three validation reports: a clickable HTML where every line unfolds into the calculation behind it, a PDF and an XLSX
  • The annexed PDFs are re-extracted from the .biztax file itself, not copied from the source. You proofread what actually goes out, not what we claim to have put in

What it does not do

  • On Biztax, a return that passes validation is submitted automatically. There is no intermediate step and no going back. Use the test file before you load the real one
  • It states its tax year, assessment year 2026, and promises nothing beyond
  • It files nothing and connects to nothing. It produces a file, you load it yourself
  • Values that cannot be derived from the accounting stay manual entries, explicit and documented
  • The tax administration changes its formats every year. Nothing guarantees this will work next year

And in every case: the module does not check your accounting. An accounting review remains essential before you file anything.

Who it is for

Companies that want to bring their return in-house without bringing the risk in with it, and accountants who would rather review a calculation than a result.
