NAADI reads your bookkeeping data and estimates your corporation tax, with a plain-English explanation of what's driving the number and where you might be able to reduce it. Most businesses find at least one saving. You get the answer months before your accountant would normally give it to you.
Planning-only estimate. Not a filed return.
Most small business owners don't know their corporation tax number until their accountant tells them, months after the year ends. By then, it's too late to do anything about it.
Your accountant knows your tax position. You don't, until the bill arrives. There's no live estimate, no dashboard, no early warning that lets you plan.
Corporation tax is due 9 months after your year ends. By the time the figure lands in your inbox, the window to plan your taxes has already closed.
A quick question to your accountant becomes an email chain. You just want to know: am I on track? Is there anything I can do right now?
Upload your bookkeeping data and NAADI reads it, estimates your corporation tax, and tells you in plain English what's driving the number and where you might be able to save.
Your home office costs weren't claimed. This is the largest untapped relief in your data. Consider adding it before year-end.

NAADI doesn't replace your accountant. It gives you, and them, a clearer picture, earlier. So when you do speak, the conversation is about decisions, not catching up on numbers you should already know.
No new bookkeeping system. Export a CSV from your existing bookkeeping software or any other standard tool and drop it into NAADI. Nothing to set up.
NAADI checks every transaction against UK corporation tax rules and flags the reliefs and deductions your data already supports. Most businesses have at least one they haven't claimed.
Every estimate and every suggestion comes with a reason. You'll know exactly what NAADI looked at, what rule applies, and what would change the number.
NAADI reads your bookkeeping data, it doesn't replace it. Keep using whatever you use today. Xero, QuickBooks, FreeAgent, spreadsheets, all work.
Every transaction NAADI classifies, every suggestion it makes, and every override you apply is logged with a rationale. Nothing is hidden.
* Based on early internal cases. Planning-only estimates. Results will vary by business.
No new software to learn. Works with what you already have.
Export a CSV from any standard bookkeeping tool. Drag and drop it into NAADI. That's the only step you have to do manually.
NAADI classifies every transaction in your file, applies the current UK corporation tax rules, and produces a directional estimate of what you owe, in under a minute. No manual input needed.
You get a plain-English breakdown of your estimate, and a list of specific suggestions where NAADI has spotted an opportunity. Each suggestion names the saving, the reason, and the action to take. Your accountant stays in the loop.
