Avoid postal delays and 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 New Year’s Eve 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. Read our news story to find out your options.

Avoid rejections

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

Accounts filed on paper need to be manually checked. We can only check them during office opening hours, and can take over a week to be processed during busy filing periods.

If you have to file paper accounts, you may want to use a guaranteed next day delivery service. Delivery could take longer than usual, due to the high volumes of post during the holiday period.

Send your accounts well before the New Year’s Eve 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.

Availability of online services

Our online services are available 24 hours a day, 7 days a week. Check your company is registered for online filing and you’re able to file your accounts using this service.

You’ll receive a penalty if resubmitted accounts are received after the deadline. File them early and allow time for this.

Filing accounts at our offices

Only our Cardiff office is manned and can receive documents during the holiday period. London and Edinburgh have a letterbox for out of hours deliveries. Our Belfast office can only accept documents within office hours.

Check our Christmas and New Year opening times before filing your accounts at one of our offices.
