Cheapest CT600 software in 2026: what filing actually costs
Compare published CT600 filing costs with the important differences in view: VAT, per-filing versus annual pricing, and whether filing accounts with Companies House is included.
The short answer
Based on published prices checked 7 October 2026, Tax Optimiser had the lowest entry price at £10 + VAT per company per year, including Companies House filing. WeFile is not the cheapest; it charges a one-off, live-priced per-filing fee. The cheapest suitable option depends on whether you need Companies House filing, supplementary pages and support for your accounts type.
Compare the cost and the filing scope
A CT600 price alone does not tell you whether statutory accounts filing is part of the package.
| Supplier | Published price | VAT | Companies House accounts filing | Price basis |
|---|---|---|---|---|
| WeFile | See checkout | Yes, for supported account types; charity/CASC filings are CT600-only. | Per filing; no subscription required | |
| Tax Optimiser | £10 per company/year; its help page describes the fee as per accounting period | Excludes VAT | Yes, included | Per company per year |
| Taxley | £49.95 per micro-company return | No VAT to add | Yes, included | Per return |
| TinyTax | £59/year for one trading company | Excludes VAT | Yes, included in the plan | Annual plan |
| Andica CT600 Cloud | From £70/year | Excludes VAT | No — submits to HMRC, not Companies House | Annual |
| CT600Filing | £79 per accounting period for a micro company | + VAT (£94.80 including VAT) | Yes, included | Per accounting period |
| #GoFile | £79.99 per filing | + VAT | Not stated as included; its CT600 page describes HMRC submission | Per filing |
| Easy Digital Filing | £119 per filing with micro iXBRL accounts | + VAT | Optional add-on: £20 + VAT | Per filing |
These prices are not perfectly like-for-like: some are per filing, others are annual or per accounting period, and package scope differs. Prices may have changed since 7 October 2026. Check the supplier’s current terms before buying.
What affects CT600 filing cost?
VAT-inclusive or VAT-exclusive?
Compare the amount you will actually pay. A price marked “+ VAT” is not the checkout total; Taxley states that there is no VAT to add. Check each supplier’s current VAT treatment before buying.
Per filing or an annual plan?
A single return and several companies or accounting periods produce different totals under each model. A statutory period of account longer than 12 months can require two CT600 returns, even where the accounts cover one longer period.
Is Companies House filing included?
Submitting iXBRL accounts to HMRC is not the same as filing statutory accounts with Companies House. Some suppliers include that second submission, some sell it as an add-on, and others do not state that it is included.
Which accounts presentation do you need?
Check support for your actual accounts type: dormant, micro-entity FRS 105, small-company FRS 102 Section 1A or full FRS 102. A low advertised price for a micro return may not apply to another accounts type.
Are your supplementary pages supported?
Confirm the pages your company needs before comparing prices. WeFile supports CT600A and CT600E, but not CT600B–D or CT600F–P. Charity and CASC filings through WeFile are CT600-only.
What happens if you amend?
Check the supplier’s current amendment scope and charges, including whether revised Companies House accounts can be filed when needed. Do not assume an advertised original-return price covers an amendment.
Self-file or appoint an accountant?
If you can prepare and review accurate figures, software may suit you. More complex circumstances may call for professional advice. Ask an accountant for a quote rather than relying on an unsourced market-average fee.
How to work out the true cost
Run these checks against your own filing needs before choosing the lowest advertised price.
- Add VAT to prices that exclude it.
- Add any Companies House accounts filing charge.
- Calculate the total for your companies and CT600 accounting periods.
- Confirm your accounts type and required supplementary pages are supported.
- Check whether the trial-balance import you need is available.
WeFile isn’t the lowest published price — here’s what the fee covers
WeFile offers pay-per-filing pricing without a subscription requirement. For supported companies, one workflow prepares the CT600 and Companies House accounts, calculates Corporation Tax automatically and generates iXBRL accounts.
It supports CT600A and CT600E and trial-balance import from Xero, QuickBooks, FreeAgent and CSV. CT600E charity/CASC filings are CT600-only. WeFile appears on HMRC’s Corporation Tax commercial software suppliers list; this is not an endorsement, accreditation, approval or guarantee of acceptance.
