Do I need to file a company tax return?

A few plain questions, no figures, no jargon. We'll tell you exactly what your company has to file.

Is your business a limited company?

A limited company has a company number from Companies House (it ends in 'Ltd' or 'Limited').

Does my company need to file a tax return?

If you run a limited company that traded or earned money, you must file two things: yearly accounts to Companies House and a Company Tax Return (the CT600) to HMRC, even if you made a loss. A company that has never traded files simpler dormant accounts and can tell HMRC it is dormant. But if your company has ever traded (even if it is quiet now), HMRC usually still expects a return for the time it was active, and you have to tell HMRC properly before it is treated as dormant, so you may still owe a return: check with us first. And if HMRC has sent you a letter asking for a return, you must file that return even if the company is dormant.
