UK companies pay corporation tax at 19 percent on profits up to £50,000, and 25 percent on profits above £250,000. Profits in between are taxed on a sliding scale through marginal relief. Getting the rate wrong, or missing the payment date, is one of the most common and most expensive mistakes a growing company makes.
We calculate your liability correctly against these thresholds, prepare and file your CT600 return, and manage the payment deadline separately from the filing deadline. Your corporation tax figures come directly from your statutory accounts, and both are built on the same accurate bookkeeping throughout the year.
Corporation tax is due 9 months and 1 day after your accounting period ends, but your CT600 return is not due until 12 months after that same date. Many directors assume the two deadlines match, then find they owed HMRC payment three months before the return was even due. This is exactly why payment planning needs to start well ahead of the return itself. We calculate what you owe as soon as your year end figures are ready, not when the return is finished.
