...the short answer is 9 months and one day after your company's year-end. So, for example, if your company's year-end is February 28th, your corporation tax needs to be paid to HMRC by 1st December of the same year. The corporation tax return itself however doesn’t actually have to be filed until the anniversary of the company’s year-end, so 3 months after payment is due! But you probably know this, right? And you're relaxed knowing that we'll take care of it all. All you need to do is provide us with the relevant documentation, pay HMRC when it's due and pass this on to a business owner who might need to know! . . . #corporationtaxuk #ukcorporationtax #hmrctax #taxadviceuk #accountantsuk #accountantsessex #kca
