Frequently Asked Questions
What is Corporation Tax and does my small business need to pay it?
Corporation Tax is a tax on the profits your limited company makes from trading, investments, and selling assets. If your business is registered as a limited company in the UK, you’ll need to pay Corporation Tax, even if you only make a small profit.
How much Corporation Tax will my small business pay?
The amount depends on your annual profits. As of now, businesses with profits up to £50,000 pay 19 percent. If your profits are higher, you may pay up to 25 percent, with marginal relief applied between the two thresholds.
When do I need to pay Corporation Tax?
You must pay Corporation Tax within nine months and one day after the end of your company’s accounting period. For example, if your financial year ends on 31 March, your payment is due by 1 January the following year.
Can I reduce my Corporation Tax bill?
Yes. You can claim allowable expenses, capital allowances, and reliefs such as Research and Development tax credits. Reviewing your salary and dividend structure can also help reduce your overall tax liability.
What happens if I miss the Corporation Tax deadline?
Missing the deadline can lead to penalties, interest charges, and even HMRC investigations. Filing your company tax return late may result in an initial £100 fine, with further charges if the delay continues.
