This project is retro technology. It takes as input a file containing UK corporation tax calculations in iXBRL form. It then takes HMRC's CT600 form and annotates the computations into the form.
The output is a PDF file which could in theory be filed with HMRC, if HMRC were still accepting CT600 forms, which they are mostly not.
It is designed to use the output of gnucash-ixbrl with the
corporation-tax.yaml configuration. It may work with other sources of
iXBRL. Or not.
- There is no warranty.
- This is likely incomplete - it does what I want, but you shouldn't be playing with this project unless you're prepared to do some work checking the values are right for you, and possibly adding extra annotations to the form which aren't covered.
- It doesn't know about all the CT600 fields.
- The CT600 form changes periodically, which will invalidate the annotations specification. The annotations spec here has absolute PDF form positions.
There is a set of computations here:
./ixbrl-to-ct600 -DN 'Sarah McAcre' -C 06
You should get an output file in output.pdf.
The file spec.json describes how to annotate the form. Each entry is a
list, first field is iXBRL tag name. Second is annotation type, which is a
type name from the annotations.py file. The rest of the entry is arguments
passed to the constructor.
