What deadlines do I need to know as a contractor?

As a contractor running your own limited company, you need to be aware of the following deadlines:

• File end of year accounts to Companies House:  9 months after your company year ends. If it is your first year, the due date will be 21 months from the date your company was incorporated.
• File your confirmation statement: This is due on the anniversary of incorporation each year
• File your corporation tax return: This is due 12 months from your company year end.
• Pay your corporation tax bill: Payment is due 9 months and 1 day after the end of the company year
• PAYE RTI (Real Time Information) Returns: A submission of your company payroll has to be submitted in real time each month to HMRC. This is due on or before the intended salary payment. Any tax due from this can be payable on a quarterly or monthly basis as follows:
• the 22nd of the next tax month if you pay monthly
• the 22nd after the end of the quarter if you pay quarterly
• VAT returns: Usually submitted on a quarterly basis, the company VAT is due to be filed and paid within 1 month and 7 days from the quarter end.
• Self Assessment tax returns: Your Self Assessment Tax Return is always due to be filed by the following 31st January after the end of the tax year. This date is also the same deadline for payment of any tax due but you may also have a payment on account due by 31st July after this.
• P11D: The submission of the company P11D will need to made by 6th July with any payment of National Insurance arising due by 19th July (22nd if paid electronically)
