Popular FAQs

Still have questions? Here are the answers to some of the most common questions people ask about Duport.

Limited Companies must submit a Company Tax return annually with HMRC

Your Company Tax Return is a report to HMRC that details your business income, spending and calculates your company’s Corporation Tax liability.

Your Company Tax Return must be submitted, and your Corporation Tax bill must be paid within 9 months of your year end date.

Companies House will set a Limited Company's year end as the last day of the month you formed the company - starting from the next year. So if you formed your company on 19th March 2022, your first year end would be 31st March 2023.
