When you're a business owner, every season is tax season - it’s imperative that you keep your accounts on track by staying up to date with multiple HMRC dates in your calendar. These include: VAT returns, personal tax returns, and corporate tax filing deadlines to name just a few. Keeping track of critical deadlines is important to ensure that you’re paying your accounts on-time.

Every registered business must assemble accounts that report on their businesses performance over the financial year. As a business owner, the choice for your accounting year-end is completely up to you. However, it's important to remember that the date you choose will determine the date you file your Company Accounts, Corporation Tax Return and pay corporation tax on your profits each year.

Deadline for filing first company accounts

For all new business owners, the first initial accounting reference date is set to the last day of the month to align with the first anniversary. Subsequently, the first accounting reference date will automatically fall on the same day each year. Companies have the choice to make up their accounts to the accounting reference date or a date up to seven days either side, if this is more convenient.

Deadline for first accounts (covering a period of 12 months or more)

  • Private Company / Limited Liability Partnership - 21 months
  • Public Limited Company - 18 months

Normal Deadline (After Your First Year)

  • Private Company / Limited Liability Partnership - 9 months
  • Public Limited Company - 6 months

Tax Year Dates

The UK’s tax year, also known as ‘the financial year’ is an important date for business owners to keep in mind - the current tax year ran from 6th April 2022 to 5th April 2023.

For the tax year dates of 2023/24, here’s what you need to know:

  • 2022/23 tax year: 6 April 2022 – 5 April 2023
  • 2023/24 tax year: 6 April 2023 – 5 April 2024

Self Assessment Tax Return Deadlines

Self Assessment Registration Deadline (5th October)

Self assessment tax return is applied to business owners whose income isn’t automatically taxed by their employers through PAYE (pay as you earn). If you are outside of a PAYE code, you’re responsible for paying tax and National Insurance Contributions (NICs) on any income you’re receiving.

You will need to register for self assessment registration with HMRC.

You need to complete this by 5th October of the year following the end of the tax year. You can do this online or by the post.

Self Assessment Tax Payment and Filing Deadlines (31st January 2024)

Once you’ve completed the registration process, you must file your self assessment tax returns each year - HMRC will then use your return to calculate whether you need to pay taxes and how much you owe.
You will need to keep financial records (for example receipts and bank statements) all throughout the year so that you can file your return accurately. Once you know how much you owe, you can pay your outstanding tax.

The deadlines are as follows for 2022/23:

  • Self assessment paper tax return - 31st October 2023
  • Self assessment online tax return - 31st January 2024
  • Self assessment tax payment: 31st January 2024

VAT Deadlines

VAT Registration Deadline

If your turnover exceeds £85,000 you will need to register and charge VAT (Value Added Tax) on the goods and services that your business sells. You’ll need to file regular VAT returns to report an accurate value of what you owe. This also allows you to reclaim some of the tax you pay. HMRC also gives the option for businesses to register for VAT if turnover does not exceed £85,000.

If you realise that your annual total of taxable turnover is going to go over £85,000 in the next 30 days - you need to register within 30 days of realising.

VAT Payment and Filing Deadlines

VAT returns are usually generally filed and paid quarterly. Specific dates will vary from business to business, so it’s important to work out your individual timeline.

Once registered, you can determine your VAT payment dates online at GOV.com.

PAYE Deadlines

If you have recruited employees, you are required to meet certain PAYE obligations. A PAYE scheme means you are responsible for withholding income tax and NICs from employees salaries and passing them onto HMRC.

Annual Registration Deadline (4th April)

You must register for payroll benefits online and the deadline to register for this is 4th April.

PAYE Remittance Deadlines

PAYE is typically calculated and paid each month.

  • PAYE remittance on paper - 19th of each month
  • PAYE payment through the internet is due on the 22nd of each month

Deadline for P45 and P60

After each tax year, you must issue the official documents to each employee.

P45 form deadline: to be sent out when an employee leaves a company

P60 form deadline: for the tax year 2021/22 is 31st May

P11D deadlines if you provide your employees with benefits

Cars, child-care and interest-free loans are known to be ‘benefits in kind’ and are advantages outside of tax and insurance payments.

P11D deadline for 2021/22 tax year: 6 July

Corporation Tax for Limited Companies

Each year, limited companies are required to pay corporation tax on their profits.

If you run a limited company, you must register for corporation tax and file for an annual tax return that calculates how much tax you owe. Your registration date determines your company's accounting period - after this accounting period ends you must pay your taxes (or report if you have nothing to pay).

The deadline to register for a corporation tax is three months after the start of your business.

The deadline for paying corporate tax is nine months after the end of your accounting period.
