NAADI

NAADI estimates your UK corporation tax position months before you file, not weeks. The site claims a CT estimate generates in under 60 seconds. That early number gives you and your client room to actually plan, rather than just reporting what already happened. The difference between an estimate in March and one in November is the difference between planning and damage control.

The tool reads your bookkeeping data and classifies transactions automatically. Every classification comes with the reasoning behind it, so you can check the logic instead of trusting a black box. This is the chunk of work that normally eats hours of an accountant's week, and cutting it out is where most of the time saving for a busy practice actually shows up. Hours your team could spend on clients instead.

NAADI flags the reliefs that apply to a client's position, which matters when reliefs get missed simply because nobody had time to look. It surfaces these before filing, when they can still change the outcome. For a practice processing hundreds of small companies, catching one extra relief per client across the base adds up to real money that would otherwise stay on the table.

Alongside reliefs, NAADI flags risks in the tax position. Knowing where a return might draw scrutiny early gives your team time to shore things up, not scramble at the deadline. Big difference.

The tool looks at deductions and identifies savings opportunities across the client base. For practices, this turns a purely compliance job into something closer to planning work. That's the shift that makes a practice worth more to its clients, since a firm that finds money is easier to justify keeping than one that only ticks boxes.

Every estimate shows 100% of its working. Nothing arrives as an unexplained figure, so you can trace how each number was reached and stand behind it with a client. Accounting work needs that paper trail, and NAADI builds it in from the start, which matters when a client or a reviewer asks exactly why a figure landed where it did. No guessing where a figure came from.

Clients get a plain-English view of where they stand, so your team stops fielding the same "what's my CT number" emails. Better visibility early means fewer panicked conversations later. Less chasing, more advising. That reduced back-and-forth is one of the quieter wins, since advisory time is what clients actually pay for.

NAADI is explicit that it produces planning-only estimates, not filed returns, and nothing goes to HMRC. Treat it as a planning and visibility layer that sits ahead of the actual filing work. That distinction matters, because it means NAADI complements whatever filing or compliance software your practice already runs rather than trying to replace it, so you're adding a layer rather than ripping out an existing workflow.
