We built this for UK Ltd contractors first. Now we are extending the same engine to small businesses, agencies and growing teams — the same figures traced to statute, the same qualified accountant signing them off, pointed at a payroll and a set of books rather than one director. This part is not open yet. Register below and we will tell you the day it is.
One email when Nebula opens to teams — nothing else. No commitment, no card.
We'll be in touch as Nebula opens to teams. In the meantime the IR35 Hub is free to use right now, and the contractor service is further along.
Every figure comes from the tax rules themselves — the AI is never allowed to invent one — and a qualified accountant signs off every filing and figure we produce for you. (The free IR35 Hub is automated end to end.) None of the below is open yet; this is what we are building toward.
Quarterly MTD and VAT returns drawn straight from the bank feed, for you to review and approve rather than assemble.
Every transaction categorised and reconciled as it lands, with the “can we claim this?” questions answered in plain English.
Your company's tax bill worked out from the legislation, with the reliefs you're entitled to applied and the arithmetic shown — plus what's due, and when.
Roles for the founder, the finance lead and your own accountant, all working from one set of figures rather than three spreadsheets.
