How it works →

Everything you need to look after a dormant company.

Once you know what your company needs, DormantFile takes care of it, and keeps an eye on it after.

File

File without becoming an accountant.

Your accounts go to Companies House, and your tax return to HMRC when it asks for one. Each takes about two minutes, as a few questions you can answer.

  1. Step 1: Answer plain questions

    Did any money move in or out this year? You answer questions about your company, not accounting forms.

  2. Step 2: Check it before it goes

    You see the exact accounts we'll send, as you'd print them. Nothing is sent until you say so.

  3. Step 3: Filed direct, and you'll know

    It goes straight to Companies House, and to HMRC when it has asked for a tax return. We email you when it's accepted.

  • Money moved but the company didn't trade, like repaying a Bounce Back Loan? We file short micro-entity accounts instead.
  • When HMRC writes asking for a Company Tax Return, we file that too, showing nothing to pay. For an LLP, it's the Partnership Tax Return.

What we file for your type of company

For companies that aren't trading. You don't need to pick: the check reads your company's type from Companies House.

Watch

Filing is one day. We watch the other 364.

All year, we keep an eye on the company and tell you when something needs you. You don't have to keep remembering it all yourself.

  1. 1Reminders 90, 30, 14, 7, 3 and 1 day before your accounts and confirmation statement are due — and we remind you about any Corporation Tax or partnership return deadline you add.
  2. 2Each director's ID check, read from the register: who has verified, who still has to, and by when.
  3. 3The public register, checked daily for changes to its directors, address, owners or name, and for any strike-off notice. We email you if one appears.

Letters

Government letter? Show us.

Photograph it and we'll tell you what it is — then do something about it.

  1. 1What it is, in plain English, and the one thing worth doing next.
  2. 2A penalty? We check your filing history and Companies House's public record for a reason to appeal, and write the letter if there is one. The check is free with a free account; the letter is £9.99.
  3. 3On a plan, the tax reference and period printed on an HMRC letter are offered as actions you confirm, and the return it asks for is filed.
  4. 4On a plan, every letter is kept with the company it's about.

Free to try — two letters a day, no account needed. On a plan we keep every letter and file the return a notice asks for, from £19/year.

Built specifically for dormant companies.

Accounting software does a lot, because a trading business needs a lot. A dormant company needs a handful of things done right, so DormantFile does those and leaves out the rest.

Accounting software is built for trading

  • Bookkeeping
  • Invoices
  • Payroll
  • VAT
  • Bank feeds
  • Accounts for a trading business

A dormant company needs this, and only this

  • What needs filing
  • When it's due
  • Filing it
  • Knowing it was accepted
  • Keeping an eye on the company
  • Making sense of the letters

Is your company trading? Then you need an accountant or accounting software — we only file for companies that aren't.

Can you trust it with your filings?

Here's exactly what happens to your filings and your details.

  • You approve every filing

    Nothing is sent until you've checked it and said so. Autopilot asks too: it emails you each year and files only when you confirm.

  • HMRC login never stored

    Your HMRC login (your Government Gateway user ID and password) is used once, when you file, and never saved. Your Companies House code isn't kept either, unless you save it for autopilot. Then it's encrypted.

  • Filed direct with Companies House and HMRC

    Through their own filing services, the same ones the big accounting software uses.

  • A record of every filing

    Once a filing is accepted, you get a receipt with its submission reference, and we keep a copy of what was sent.

Card payments go straight to Stripe; we never see your card details. How we handle your data

Counted fresh today.

This is an excellent website. Loads extremely fast, very clean and well designed. […] I liked their honest comparison of their various competitors, definitely a breath of fresh air. […] Fairly priced for the service offered. I'm not one to leave reviews usually but this was an excellent experience so I'm happy to recommend.

Ben Davies, founder of DormantFile

Built by someone who wanted this to be simpler too.

I'm Ben Davies, a UK software engineer. I look after dormant companies of my own, and when HMRC closed its free filing service I built DormantFile to file them: from scratch, for dormant and non-trading companies and nothing else.

If you email us, you'll hear back from me. We aim to reply within one working day.

You're probably wondering

The things we'd want to know before signing up. See all FAQs →

01

How do I know if my company is dormant?

A company is dormant if nothing significant went through its books all year: no sales, no spending, no money in or out. A few payments don’t count, such as the confirmation statement fee or a late-filing penalty. Dormant doesn’t mean empty, either. A company that traded once and still owes money, is owed money or holds assets can be dormant, as long as nothing about those figures changes. Not sure? Try the Am I dormant? checker.

02

What exactly does DormantFile file?

Your company’s annual accounts, to Companies House: dormant accounts, or short micro-entity accounts if money moved but the company didn’t trade. And when HMRC writes asking for one, its Company Tax Return (form CT600) showing nothing to pay — or, for an LLP, its Partnership Tax Return (SA800). We don’t file the confirmation statement, a community interest company’s accounts, or accounts for a company that’s trading.

03

Do I need to file with HMRC?

Only if HMRC has asked. A Company Tax Return is due when HMRC writes asking for one (a ‘notice to deliver’), usually every year until it records the company as dormant. No letter, no tax return. Your accounts go to Companies House either way.

04

What if my company has a Bounce Back Loan?

If the company is repaying one, it isn’t dormant, even if you make the repayments yourself: the money still moves through the company’s books. It can still file short micro-entity accounts (FRS 105) instead, and we file those for you.

05

Is my HMRC login stored?

No. To file a tax return you enter your HMRC login (your Government Gateway user ID and password). It’s used once, when you file, and deleted straight away. Your Companies House code is only kept if you save it for autopilot, and then it’s encrypted. How we handle your data.

06

What happens if a filing is rejected?

We show you why in plain English. Fix it and resubmit, free, as many times as you need: your plan covers every attempt. A rejected filing doesn’t count as accepted, so the 14-day refund still applies while you put it right.
