What counts as a billable return?

Only a return accepted by HMRC on the live service. Rejected returns, test submissions and HMRC validation checks are never charged.

Can I change plan later?

Yes. Change plan at any time from the Billing page. The change applies from the start of the next billing period.

How much does it cost?

Pay as you go is £3.50 + VAT for each return HMRC accepts, with no monthly fee. Contract bundles cost £50 a month for 20 submissions, £75 for 30 or £100 for 40 — £2.50 a return.

Is there a free trial?

You can create an account, set up your firm and prepare returns before you commit. You only pay when a return is accepted by HMRC (pay as you go) or when you choose a contract bundle.

Do prices include VAT?

No. All prices exclude VAT, which is added at the standard rate.

What happens if I go over my bundle?

Each accepted return over your monthly bundle is charged at the pay-as-you-go price of £3.50. You are never blocked from filing, and you can move to a bigger bundle from your next billing month.

Which option is cheaper for me?

Pay as you go is cheapest up to 14 returns a month. The 20-submission contract is cheapest from 15 to 27 returns, the 30-submission contract from 28 to 37, and the 40-submission contract from 38 returns. The calculator on the pricing page works it out for you.

Can it integrate with our case management system?

Yes. We offer an integrated option that works alongside your existing case management software. Contact us for prices and details.
