Charity discount — claiming 25% off as a registered charity

Registered charities get 25% off either OneSixth plan (Practice or Business). We accept Charity Commission, OSCR and CCNI registration numbers, and HMRC CASC clubs by name. The discount is retroactive from when you provide your details.

If your organisation is a registered charity, you qualify for 25% off whichever OneSixth plan you're using. The discount stacks with both annual billing (saving 15% on top) and, on the Practice plan, with the graduated volume tiering — so a charity practice with 10 client orgs gets the second-tier per-org rate, then 25% off that.

We're not aware of another UK VAT compliance tool that lets the charity discount stack with volume pricing. If your organisation is mission-aligned, we don't think you should be penalised for scale.

Eligible registers

We verify discount eligibility against four UK registers:

  • Charity Commission for England and Wales — registered charity number (e.g., 1234567).
  • OSCR — Office of the Scottish Charity Regulator — Scottish charity number (e.g., SC012345).
  • CCNI — Charity Commission for Northern Ireland — Northern Ireland charity number (e.g., NIC101234).
  • HMRC CASC — Community Amateur Sports Clubs — for clubs registered with HMRC under the CASC scheme. HMRC doesn't publish reference numbers, so you simply search for your club by name.

How to claim it

  1. From billing settings, mark your firm as a charity and pick which register you're listed on.
  2. For Charity Commission, OSCR or CCNI, enter your registration number. For a CASC, search for your club by name and select it from the list.
  3. We verify against the relevant public dataset — typically within one working day. Charity Commission and OSCR verify automatically; CCNI and CASC verify against our nightly-synced register.

Retroactive application

The discount applies from the moment you provided the registration number, regardless of when verification completes. If verification takes three working days, the first invoice after verification credits back the difference for those three days. You don't lose money to our review queue.

How the stack works

For a Practice plan firm: the 25% applies to the graduated per-org rate at each tier band. So a 10-org charity practice gets the second-tier rate per org × 10, then 25% off that, then 15% off if billed annually.

For a Business plan firm: the 25% applies to the flat monthly rate for the entity-count tier. Annual billing discount layers on top in the same way.

What if the registration changes

If a charity loses its registration, we don't claw back historical discount — they paid the discounted rate while registered, and that stands. Future billing returns to the standard rate from the date the registration ended. The reverse holds for an organisation that becomes a charity: the discount applies prospectively from the date the registration number is provided.
