Every season is tax season when you’re a small business owner<\/mark><\/a>. HMRC specifies multiple dates in your calendar, including VAT returns, payroll, personal tax returns, and corporate tax<\/mark><\/a> filing deadlines.<\/p>\n\n\n\n

Everything will run smoothly if you submit your tax returns on time and keep track of deadline for filing company accounts<\/strong>. Here’s a list of the financial and tax dates and deadlines to watch in 2026\/27.<\/p>\n\n\n\n

Tax Year Timelines and Dates 2026\/27<\/h2>\n\n\n\n

First, it’s essential to understand that the UK’s tax year differs from the ordinary calendar year. The tax year, sometimes known as “the financial year,” pertains to employed and self-employed tax concerns.<\/p>\n\n\n\n

The start and end of the tax year dictate many of the dates in this guide. As we are already into 2025\/26, the new tax year will impact your accounting timetables.<\/p>\n\n\n\n

\"Hire<\/a><\/figure>\n\n\n\n

When does the tax year begin?<\/h2>\n\n\n\n

The UK tax year typically runs from 6 April to 5 April<\/strong> of the following year. As a result, the start and end dates for the current tax year 2025-26 are 6 April 2025 and 5 April 2026.<\/p>\n\n\n\n

The time between these two is “within the tax year.”<\/p>\n\n\n\n

Understanding how the tax year works is critical to getting any money you owe and avoiding penalties for missing deadlines. <\/p>\n\n\n\n

It may appear complicated, but you can easily calculate important dates as long as you know when your year begins and finishes.<\/p>\n\n\n\n

Here’s what you should know about the 2024\/25 tax year.<\/p>\n\n\n\n

\u25cf 2025\/26 fiscal year: 6 April 2025 \u2013 5 April 2026<\/strong>
\u25cf The tax year 2026\/27 runs from 6 April 2026 through 5 April 2027<\/strong>.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Self Assessment tax return deadline<\/strong><\/h2>\n\n\n\n

Self-assessment tax<\/a> <\/mark>applies to individuals whose earnings are not automatically taxed by their employers under the PAYE (“pay as you earn”) scheme. Any income you get outside the PAYE tax code is your responsibility to pay taxes and National Insurance Contributions<\/mark><\/a> (NICs).<\/p>\n\n\n\n

If you’re self-employed, a lone trader, a partner, or a business director, you must register for, file, and pay Self Assessment taxes.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Self-Assessment tax registration<\/strong><\/h3>\n\n\n\n

You must register with HMRC if you have never submitted a Self Assessment tax return or did not file one the previous year. You must complete it by 5 October after the end of the tax year, for which you must file a return.<\/p>\n\n\n\n

So, if you want to file a return for the fiscal year 2026\/27, you must do so by 5 October 2026.<\/p>\n\n\n\n

GOV.UK allows you to register online.<\/p>\n\n\n\n

\u25cf The last date for filing your self-assessment tax return is 5 October.<\/p>\n\n\n\n

Who Needs To Complete a Self Assessment Tax Return?<\/mark><\/strong><\/a><\/p>\n\n\n\n

Self-Assessment tax payment and filing deadlines<\/strong><\/h3>\n\n\n\n

You must file your tax returns<\/a> every year once you’ve registered. HMRC will use your tax return to determine if and how much you owe in taxes.<\/p>\n\n\n\n

To complete your tax return correctly, keep track of your finances for the year (such as receipts and bank statements). After filing your return and determining how much you owe, you can pay your unpaid taxes.<\/p>\n\n\n\n

You can submit the self-assessment tax returns<\/a> by filing them online or sending them in a paper return.<\/p>\n\n\n\n

The following are the filing and payment deadlines for the 2025\/26 tax year.<\/p>\n\n\n\n

\u25cf Filing a self-assessment paper tax return is due on 31 October 2026.
\u25cf The Last date for filing a self-assessment tax return online is 31 January 2028.
\u25cf The deadline to pay self-assessment taxes and the first payment on account is 31 January 2028.<\/p>\n\n\n\n

Check our guide on: <\/mark>How to Submit a Self-Assessment Tax Return<\/mark><\/strong><\/a><\/p>\n\n\n\n

When are late payment penalties imposed?<\/h3>\n\n\n\n

You’ll face penalties if you don’t file or pay your Self-assessment taxes by the deadline. If you file your return after the last date but within 3 months, you incur a \u00a3100 fine. If you file later, you’ll have to pay more.<\/p>\n\n\n\n

GOV.UK allows you to estimate penalties if you submit late Self Assessment<\/a> tax returns or payments.<\/p>\n\n\n\n

VAT Return Dates and Deadline<\/strong><\/p>\n\n\n\n

Companies that meet specific criteria must charge a tax on the goods and services (known as VAT). In the UK, for example, if your annual turnover exceeds \u00a390,000, you must register, charge VAT to your consumers, and pay the tax to HMRC.<\/p>\n\n\n\n

To disclose what you owe, you’ll complete regular VAT returns. Returns also allow you to reclaim part of the tax you paid to your vendors, so keeping your records and returns updated is to your best benefit.<\/p>\n\n\n\n

Check our : A quick guide to VAT when you are self-employed<\/strong><\/a>.<\/p>\n\n\n\n

VAT registration deadline<\/strong><\/p>\n\n\n\n

If your annual sales exceed the VAT level, you must register for VAT. Even if it is not required, some companies may opt to sign up, and you can do so at any moment.<\/p>\n\n\n\n

You must register by a specific deadline in one of two scenarios:<\/p>\n\n\n\n

\u25cf You must register within 30 days of knowing that you will surpass the VAT threshold in the coming month.
\u25cf If you exceed the barrier in the previous 12 months and have not yet registered, you should do so within 30 days after the end of the month in which you exceeded it.<\/p>\n\n\n\n

VAT payment and filing deadlines<\/strong><\/p>\n\n\n\n

VAT returns are typically filed and paid quarterly, one calendar month, seven days after the end of the accounting period. Because you determine when your quarterly period begins at registration, specific dates vary from business to business.<\/p>\n\n\n\n

Your timetable will cover 12 months; however, it may not correspond to calendar quarters. As a result, it’s critical to keep track of your timeframes.<\/p>\n\n\n\n

Once you register, you may determine your VAT payment dates online at GOV.UK. You may be subject to surcharge penalties if you pay your VAT taxes late.<\/p>\n\n\n\n

PAYE deadlines if you run a payroll system<\/mark> for your employees’ salaries<\/h3>\n\n\n\n

If you have employees on your payroll, you must meet certain PAYE obligations. Employers who pay through the PAYE plan are responsible for withholding income tax<\/a> and NICs from their employees’ salaries and remitting them to HMRC.<\/p>\n\n\n\n

Checkout our guide on : What is payroll \u2013 Your guide to Payroll year-end<\/strong><\/a>.<\/p>\n\n\n\n

PAYE requires you to register for payroll benefits and meet monthly remittance and payment responsibilities to HMRC. You must also file benefit papers on your employees’ behalf every year.<\/p>\n\n\n\n

Annual registration deadline<\/strong><\/p>\n\n\n\n

Before starting each tax year, you must register for payroll benefits online.<\/p>\n\n\n\n

\u25cf The deadline to register for PAYE is 4 April.<\/p>\n\n\n\n

<\/p>\n\n\n\n

PAYE remittance deadlines<\/strong><\/p>\n\n\n\n

PAYE usually is calculated and paid every month. You have two alternatives for sending remittances: by mail or online. Your payment dates will be determined by which option you select.<\/p>\n\n\n\n

\u25cf PAYE remittance on paper: 19th of each month
\u25cf PAYE payment through the internet is due on the 22nd of each month.<\/p>\n\n\n\n

GOV.UK has more information about PAYE reporting and remittance.<\/p>\n\n\n\n

Deadlines for P45 and P60 forms <\/strong><\/p>\n\n\n\n

You must keep HMRC informed about payroll benefits, but notify your employees. You do so by issuing official documents to each employee after each tax year and a P45 form to each employee when they leave your company.<\/p>\n\n\n\n

There is no fixed deadline for submitting P45 forms. The P60 form is due at the end of the month after the tax year.<\/p>\n\n\n\n

\u25cf P45 form deadline: When an employee leaves your company.
\u25cf P60 form deadline for the 2025\/26 tax year is 31 May 2026, and 2026\/27 is 31 May 2027.<\/p>\n\n\n\n

GOV.UK has extra information about P45 and P60 forms and other benefits forms.<\/p>\n\n\n\n

P11D deadlines if you provide your employees with benefits<\/strong><\/p>\n\n\n\n

If you give employees “benefits in kind,” you may be required to submit P11D papers to HMRC. Cars, childcare, and interest-free loans are advantages outside of tax and insurance payments.<\/p>\n\n\n\n

These forms are due three months after the end of the tax year. You’ll need to complete a separate form for each employee who received these benefits. Employers frequently give employees a copy of the document.<\/p>\n\n\n\n

P11D deadline for 2025\/26 tax year: 6 July 2026 and 2026\/27 tax year: 6 July 2027<\/strong> <\/p>\n\n\n\n

Due dates for capital gains taxes<\/a> for sole traders and partnerships<\/strong><\/p>\n\n\n\n

If you’re a sole trader<\/a>, self-employed, or a partner in a partnership, you may have to pay capital gains tax (CGT) and standard income tax. When you sell or dispose of a company asset, you must pay CGT.<\/p>\n\n\n\n

For instance, if you sell a company-owned facility or give away gear that you use in your firm, you pay tax on the increase in the asset’s value since you purchased it.<\/p>\n\n\n\n

You can immediately pay it if you know how much capital gains tax<\/a> you owe. If not, you must include them in your self-assessment tax return for the year you realised the gain.<\/p>\n\n\n\n

So, for the 2026\/27 tax year:<\/p>\n\n\n\n

\u25cf You must pay capital gains tax on assets sold in 2026\/27 before 31 January 2028.<\/p>\n\n\n\n

Corporation tax for limited companies<\/strong><\/p>\n\n\n\n

Every year, limited companies must pay a corporation tax<\/a> on their profits. If you run a limited company, you must register for corporation tax<\/a> when you start trading and file an annual company tax return calculating how much you owe.<\/p>\n\n\n\n

Your registration date determines your company’s “accounting period,” which may or may not coincide with your fiscal year. After the accounting period, you must pay (or report if you have nothing to pay) your taxes and complete a company tax return for the year.<\/p>\n\n\n\n

Here are the important dates to remember:<\/p>\n\n\n\n

\u25cf The deadline to register for corporation tax is three months after starting the business.
\u25cf The deadline for paying corporate tax is usually nine months and one day following the end of your accounting period.
\u25cf The last date to file a business tax return is usually 12 months after the accounting period.<\/p>\n\n\n\n
