  • ct600_filing_guide

    READ THIS FIRST. How to prepare a CT600 with this server: which companies qualify, the order to gather figures in, what the words mean (micro-entity, filleted accounts, the declaration), and which cases to refer to an accountant instead. Takes no arguments.

  • lookup_uk_company

    Look up a UK company at Companies House by company number: name, status, registered office, next accounts period, and a quick fit check.

  • compute_ct600

    Compute the corporation tax position from figures (stateless, nothing stored): tax due, taxable profit, marginal relief, losses, CT600 box values.
