Affiliate disclosure: we have not joined any affiliate programme yet, so no link earns us money today. If that changes we may earn a commission when you click a link and buy, and we will say so. Prices shown are the vendor's published prices. How this works.

How we compare

This page sets out the rules every comparison on this site follows. The first one is the software price table. If a page breaks these rules, that is our mistake and we will fix it.

General information only, not tax advice. Check GOV.UK or ask a qualified adviser about your situation.

What we use

What we do not do

On every comparison page

How we choose what to list and in what order

The price table does not rank products and recommends none; it lists published prices only. Criteria for any ranked list will be published here before that list goes live. Ranking will be based on those criteria, such as listing in HMRC's official list, published price, and features the vendor states publicly. We do not accept payment for placement, ranking or reviews; whether a vendor pays us is not a ranking criterion.

Keeping pages current

We aim to recheck prices and terms monthly. A page not rechecked for more than 90 days is out of date, and we will say so on it.
