ByteLogic CT600

Corporation Tax filing, kept deliberately focused.

The first paid ByteLogic product is CT600 production and submission for small UK limited companies. Broader accounting modules remain inside the platform, but the customer-facing offer is now centred on Corporation Tax.

What is not in the first paid offer

VAT MTD, RTI payroll submission, open banking, and Companies House filing are parked from the first public offer. This keeps the website aligned with the CT600 recognition process and avoids promising unfinished workflows.
