Which @AdamsWinter plan is right for you? This guide answers the most common questions about pricing, billing, and what's included.

How Much Does @AdamsWinter Cost?

Our pricing is shown on the pricing page. Plans vary depending on how many companies you need to file for, so check there for the latest options and any current offers.

Which Plan Do I Need?

Filing for One Company

If you only have one company, our Solo plan covers everything you need: CT600 to HMRC and micro-entity accounts to Companies House. The Solo plan locks to the first company you file for.

Filing for Multiple Companies

If you have more than one company, you'll need a Portfolio plan. Check the pricing page for the plan that fits your situation.

ℹ Each company files separately, but you manage them all from one dashboard.

I'm an Accountant Filing for Clients

@AdamsWinter has plans designed for accountants and bookkeepers who file on behalf of multiple clients. Visit the pricing page to see our multi-company options.

Is There a Free Option?

All filings (including dormant companies) require a subscription. You can start your filing and enter all your figures before paying — you only need to subscribe when you're ready to submit.

Visit the pricing page to see current plan options and prices.

When Do I Get Billed?

You're billed when you subscribe to a plan. @AdamsWinter uses annual billing — you pay once per year and can file as many times as your plan allows during that period.

You won't be charged anything until you choose to subscribe. You can:

  1. Add your company
  2. Enter your figures
  3. Review everything
  4. Subscribe only when you're happy and ready to submit
✓ There's no commitment until you subscribe. Explore the form and see your tax calculation before paying anything.

What's Included?

All paid plans include:

  • CT600 filing to HMRC — fully digital submission
  • Micro-entity accounts to Companies House — iXBRL format, filed electronically
  • Tax computation — generated automatically from your figures
  • Automatic period splitting — if your accounting period is longer than 12 months
  • Prior year data — automatically fetched from your previous filings
  • Unlimited resubmissions — if HMRC or Companies House reject your filing, resubmit at no extra cost
There is no separate charge for submitting to Companies House — both the HMRC CT600 and Companies House accounts submission are included in your plan.

What Periods Can I File For?

@AdamsWinter supports accounting periods ending on or after 1 April 2022. This covers most current and recent filings, including periods ending in 2022, 2023, 2024, and 2025.

Periods ending before 1 April 2022 are not supported, because they require older HMRC CT600 taxonomies that @AdamsWinter does not use.

ℹ If your period ended before 1 April 2022, you will need to use HMRC's own filing service or specialist accountancy software for that return.

Can I Upgrade or Downgrade?

Yes. If you need to add more companies, you can upgrade your plan at any time. Visit the pricing page or contact us if you need help choosing.

Do You Offer Refunds?

All subscription fees are non-refundable. However, refunds may be issued at our discretion in exceptional circumstances — contact us at hello@adamswinter.com if you'd like to request a review.

Common Questions

Q: I have 3 companies — do I need 3 separate plans? A: No. Our Portfolio plan covers multiple companies under one subscription. Check the pricing page for the right option.

Q: Can I try before I buy? A: Yes! Add your company, enter your figures, and review your tax calculation — all before subscribing. You only pay when you're ready to submit.

Q: What's the difference between Solo and Portfolio? A: Solo covers one company and locks to the first company you file for. Portfolio covers multiple companies. Visit the pricing page to compare.

Q: Do you charge per filing or per year? A: Per year. Subscribe once and file as many returns as your plan allows during the subscription period.

Q: Can I claim my @AdamsWinter subscription as a business expense? A: Yes. Tax software is an allowable business expense. You can include it in your administrative expenses.

Q: Is Companies House included in the price? A: Yes. Your plan covers both CT600 submission to HMRC and micro-entity accounts to Companies House — there is no extra charge for the Companies House filing.

Q: Can I file a return for 2024? A: Yes. @AdamsWinter supports accounting periods ending from 1 April 2022 onwards, so periods ending in 2024 are fully supported.
