SimpleCompanyTax#Simple CompanyTax is listed as SimpleCompanyTax on HMRC’s Corporation Tax commercial software supplier list for CT600 production/submission, iXBRL documents and self-filers. A listing is not an HMRC recommendation or endorsement.

Choose software that matches your accounts standard, filing destinations, period dates and required claims. Check imports, amendments, long-period returns, document previews and the total annual price including VAT. Compare the supported scenarios rather than the number of advertised features.

SimpleCompanyTax#Simple CompanyTax supports eligible UK private micro-entity companies limited by shares or guarantee, including trading, dormant, property, associated companies and CICs. Separate HMRC-only routes support wholly exempt charities, including CIOs, SCIOs and charitable PTAs, CASCs and unincorporated clubs, including golf clubs. Charity and club routes use customer-prepared accounts. We do not support LLPs, PLCs, sole traders, partnerships, group accounts or partly taxable charities.

Yes. One annual subscription covers unlimited filings, amendments and accounting periods for the same company, per year. There is no extra fee for another supported accounting period or for correcting and re-filing that company. A different company needs its own subscription, unless you use a Practice plan that includes multiple company slots.

Yes, for supported company filings. You review the documents, enter your own filing credentials and select Submit. The platform sends the filing to the destinations you selected. Support staff do not send it manually. Check each authority’s response separately. CIC accounts use a separate package that you upload to Companies House yourself.

Choose Simplified or Detailed in the CIC34 report card on Financial Data and complete the questions to prepare your Companies House ZIP package, containing your accounts and CIC34 report. You download and upload it yourself through the Companies House CIC accounts service, which charges a separate £15 fee. Leave the report selector on None if you only want the CT600 filing route.

Never send card details by email.
