It’s easier to file your accounts online.

Request an authentication code, if you haven’t already got one. It’s sent by post to the company’s registered office and can take up to 5 days to arrive.

File early and file online

File online before the deadline and we’ll send you an email confirming your accounts have been received. We’ll send you another email when they’ve been registered.

It can take as little as 15 minutes from start to finish and you’ll know your accounts have been delivered on time.

If you’re a small company, you can’t file abbreviated accounts any more. To find out what your options are, read our news story.

Find out how to get your company authentication code, which you’ll need to file online.

Avoid rejections

Our online filing service has inbuilt checks to help you avoid rejection.

Accounts filed on paper need to be manually checked. They can only be checked during office opening hours, and can take over a week to be processed.

If you have to file paper accounts, you may want to use a guaranteed next day delivery service. Send your accounts well before the deadline in case you need time to resubmit them. If your accounts are rejected and need to be resubmitted, you could be too late to avoid a penalty.

Postal delays won’t be accepted as an excuse for late filing.
