Small private companies with a year end of 31 August 2017 and into their second or later year of existence should submit their accounts to Companies House by 31 May 2018 in order to avoid a Late Filing Penalty.
Any corporation tax for small companies with a 31 August 2017 year end is due to be paid on 1 June 2018 in order to avoid Late Payment Interest, which is currently charged at 3%. Our clients will be e-mailed a payment advice giving customised electronic payment details. This advice is pale blue in colour like the previous version of the corporation tax form CT600. Our standard colour for anything to do with companies or corporation tax is blue, which is also the overall colour of the Companies House website.
New small private companies in their first year of existence have a deadline for submitting the accounts which is usually slightly shorter than this unless they have changed their year end, in which case it may be considerably shorter. They can look on the Companies House website to determine their deadline, but their accountant should look out for this anyway and warn them.
If you miss the deadline then we advise you to get your accounts drawn up and submitted as soon as possible in order to avoid further issues. The requirement to be able to produce a set of accounts at high speed is one of our motives in taking an interest in new technology.
If you are over the deadline, there may be other problems such as with s455 tax and P11D returns. We can only point out that leaving things to the last minute and beyond can often turn out to be expensive, and you should see an accountant and corporation tax agent as soon as possible.
