Partial PDF signing, document templates, and calculators are buildable. Accurate tax and fee calculators for four countries need current regulatory rules and maintenance by tax domain experts.
What it would actually take: Use a PDF library for signing and templated document generation, with a web front end. The hard part is encoding tax rules for the US, UK, Canada, and Australia, including rate changes, thresholds, and edge cases, which requires accountants or tax specialists and an ongoing update process.
