Fiscari vs Tolley

Tolley alternatives: how Fiscari compares

Fiscari answers from the sources you would cite to HMRC, at a price you can read before you talk to anyone, and you can test it on real client questions first. Here is where it beats Tolley — and the three things Tolley does that we do not.

Where Fiscari is stronger

Tolley is a serious product with real editorial depth, and the question is not whether it is good. The question is whether you need a paid commentary library to answer the questions you actually get asked. For most day-to-day UK tax work the authoritative source is legislation and HMRC's own material — and that is what Fiscari is built on.

Grounded in the sources you would cite to HMRC

Legislation, HMRC manuals, VAT notices and tribunal decisions, cited at the paragraph. Tolley+ AI grounds in Tolley's own paid commentary — one interpretation of those sources rather than the sources themselves.

You can see the price before you talk to anyone

Published from £19.50 per user / month. Tolley is quote on request, so evaluating it starts with a sales call rather than with your own questions.

It refuses rather than guessing

A published refusal policy. When the sources do not support an answer you are told what was found instead, which is the behaviour you need when the answer has to survive review.

You can test it before committing

Put a week of real client questions through it and judge it on what it refuses. No annual commitment before you know whether it fits your work.

Straight about the limits

What Fiscari cannot do

Three things worth knowing before you switch, including the cases where Tolley is the better buy.

We have no proprietary commentary

No Simon's Taxes, no De Voil, no Tolley practical guidance. For a complex reorganisation, a share scheme, or genuine structuring work, that editorial judgement is worth paying for and we do not have it. Keep Tolley for those matters.
We have a shorter track record

Tolley has been in this market for decades. Every Fiscari answer is verifiable by clicking the citation, which we would argue matters more — but it is not the same thing as a forty-year reputation, and you should weigh that honestly.
The refusals are real

When the corpus does not support an answer you get a refusal, not a best guess. That is deliberate, and it will occasionally be inconvenient on exactly the question you most wanted answered.

Worth a look if…

A solo or small practice paying full bundle prices

Most of what a Tolley bundle actually gets used for at this tier — checking a VAT treatment, interpreting a manual paragraph, confirming a Corporation Tax section — is exactly what Fiscari is built for.
A mid-tier firm at renewal

Run both against twenty real questions from recent file notes. Many firms land on Fiscari as the primary research tool with an incumbent kept on a reduced contract for complex advisory.
A top-50 firm doing structuring work

Do not replace Tolley. Add Fiscari for the daily research load and keep Tolley for the matters that need the commentary.
