You filed my accounts but I got a fine from HMRC.

It is likely that you have received a penalty notice from HMRC because you did not let them know that your company is dormant (not trading). Please note: When you purchase our Dormant Company Accounts Service, this is to file your Annual Accounts with Companies House. It does not include the filing of a tax return with HMRC. Unfortunately, as we are not accountants, we are unable to provide any tax-related services. We recommend contacting HMRC immediately to explain the situation. Here are their contact details:   Inside the UK: 0300 200 3410 Outside UK: +44 151 268 0571   In future, you can let HMRC know your company is dormant using the following link: https://www.gov.uk/tell-hmrc-your-company-is-dormant-for-corporation-tax
