Frequently Asked Questions

Everything you need to know about filing your accounts with FileSimple.

FileSimple is designed for active UK limited companies that qualify as micro-entities under FRS 105. Your company qualifies if it meets at least two of the following: an annual turnover of £632,000 or less, a balance sheet total of £316,000 or less, and an average employee count of 10 or fewer.

It costs £39 to file your accounts. No expensive accounting software subscriptions are required. If Companies House rejects your filing for any reason, you can correct and resubmit it for free within 48 hours—saving you from missing your deadline and incurring a Companies House late fee (which starts at £150 for being just one day late).

If Companies House rejects your filing, we'll help you correct and resubmit your accounts for free within 48 hours.

No. This software submits your micro-entity accounts (balance sheet and footnotes) to Companies House to satisfy your public filing requirements. It does not file your Company Tax Return (CT600) or accounts with HMRC. You must file those separately through HMRC's services or tax software.

We take security seriously. All your data is fully encrypted, and your company details are kept completely secure. We never store your payment card details.
