Information You Need to Supply for Professional Help with Your Tax Return

Information You Need to Supply for Professional Help with Your Tax Return

Information You Need to Supply for Professional Help with Your Tax Return

[Updated November 2025]: If you’re self-employed in the UK and earn more than £1,000 after allowable deductions, you need to file a self-assessment tax return each year. It’s not only the self-employed, though. If you are on a higher income* or receive untaxed income from things like property rental, tips, commission, savings, investments, dividends, or foreign income, you also have to submit a return. Partners in business partnerships and those who made a capital gain resulting in Capital Gains Tax (CGT) also need to submit a return. You can check here if you’re not sure.

If you do have to fill in a self-assessment tax return, getting all the tax return fields filled in properly and the figures right can sometimes be difficult. That’s where professional help from companies like Taxfile is worth its weight in gold. But what information will your accountant or tax advisor need from you? In today’s guide, we’ll explain exactly what you’ll need to supply.

* (Those earning more than £100,000 for tax years up to and including 2022-23, or over £150,000 for the tax year 2023-24. Higher earners earning only through PAYE for tax years thereafter only need to submit a tax return if their tax was not collected correctly at source). You can check here if you’re not sure.

What Information Do You Need to Supply for Professional Help with Your Tax Return?

If you’re getting help filling in and submitting your tax return through an accountant or tax advisor like Taxfile, a list of what they will need from you follows below. You’ll need to supply information for the right financial tax year, of course, unless you have a different accounting period.

For the purpose of this post today, let’s assume information will be required for the tax year starting on 6 April 2024 and ending on 5 April 2025.

Here’s what will be needed:

Income-related information if applicable:

  • Copies of all employment income documents (P60s, P45s, and P11ds), as well as any unreimbursed employment expenses.
  • Copies of all pension income documents (P60s, state pension notices, etc.).
  • Details of bank and building society interest.
  • Details of all investment income (interest, dividends, etc.), as well as details of any investments that may qualify for relief, such as the Enterprise Investment Scheme.
  • Details of any self-employed income and expenses (schedules and paperwork).
  • Details of any rental income and expenses (schedules and paperwork).
  • Details of any assets that were sold (or gifted) and may be subject to Capital Gains Tax (CGT).
  • Details of any other income received, including foreign income.

Potential tax relief information:

  • Details of any personal pension contributions made from taxed income.
  • Details of any gifts to charity using Gift Aid.

You’ll also need to confirm if there is any other information that may be relevant to the completion of your tax return.

Personal Information:

If you’re a new client or an existing client who hasn’t supplied them already, you’ll also need to provide the following:

  • A copy of your passport or driver’s licence. This is to comply with ‘Know Your Customer’ (KYC) and ‘Anti-Money Laundering’ (AML) regulations.
  • Confirmation of any changes to your personal details, such as a change of address.
  • If you or your partner receive Child Benefit, you’ll need to provide details.
  • If you have a student loan, you’ll need to provide details of the amount you paid during the year and the remaining balance as at April 5, 2025.

Once your accountant or tax advisor receives all of your information, they will be in a position to prepare your tax return. Once approved by you, they will be able to submit it to HMRC on your behalf.

Lowering the Secondary Threshold for Employer NI – What You Need to Know

Lowering the Secondary Threshold for Employer NI – What You Need to Know

/in , , , , , /by

Lowering the Secondary Threshold for Employer NI – What You Need to Know

From April 2025, the secondary threshold for employer National Insurance (‘NI’) will be lowered. This means that employers will need to start paying employer NI contributions on their employees’ earnings sooner.

How Will This Affect Employers?

This change will affect employers in a number of ways. Firstly, employers will need to pay more in employer NI contributions. Secondly, employers will need to update their payroll systems to reflect the new threshold.

Employer NI and Employment Allowance Update

As an employer, you are responsible for deducting and paying National Insurance contributions (‘NICs’) for your employees. There are two types of NICs:

  • Employer NICs — These are paid by you as the employer.
  • Employee NICs — These are deducted from your employees’ wages.

Employment Allowance

The Employment Allowance is a relief that allows eligible employers to reduce their National Insurance contributions. The allowance increases from £5,000 to £10,500 per year from April 2025.

Increase in Employer NICs

From April 2025, the rate of Employer NICs increases from 13.8% to 15%. This means that you will need to pay more NICs for your employees.

How Taxfile Accountants Can Help

Taxfile Accountant can help you with all aspects of your payroll, including:

  • Calculating and deducting NICs
  • Claiming the Employment Allowance
  • Preparing and filing your payroll reports

We can also provide you with advice on how to minimise your NICs liability.

Capital Gains Tax Hike: A Blow to Investors

Capital Gains Tax Hike: A Blow to Investors

/in , , , , , , , /by

Capital Gains Tax Hike: A Blow to Investors

October 2024’s Autumn Budget delivered a significant blow to investors with the announcement of increased Capital Gains Tax (CGT) rates. Today, we explore the new rates, how they will affect the sale of assets, and how investors can mitigate their effects.

The New Capital Gains Tax Rates

Effective from 30th October 2024, the basic rate of CGT will rise from 10% to 18%, and the higher rate will increase from 20% to 24%.

What This Means for Investors

These changes will make it more expensive for investors to realise gains from selling assets like shares, bonds, and cryptocurrency. This could lead to a number of consequences, including:

  • Reduced investment activity — investors may be less inclined to sell assets, particularly if they expect to make significant gains;
  • A shift towards tax-efficient investments — investors may seek out tax-efficient investments, such as ISAs and pensions;
  • A greater need for tax planning — investors may require more sophisticated tax planning strategies to minimise tax liabilities.

How Can Investors Mitigate the Impact of the CGT Increases?

Investors have several ways to mitigate the worst effects of the CGT rate increases. They can:

  1. Seek professional advice — a good tax advisor like Taxfile can help investors understand the full impact of the changes and develop a tax-efficient strategy;
  2. Review their investment portfolios to identify the potential tax implications of the new CGT rates;
  3. Utilise tax-efficient investments, for example, through the use of tax-efficient wrappers like ISAs and pensions;
  4. Time investments wisely — carefully timing the sale of assets may help to significantly reduce CGT liabilities.

Taxfile is here to help proactive investors navigate the new tax landscape and protect wealth. Contact us today if you would like professional help with any tax or accountancy-related issue. We’ll be delighted to help. The first 20-minute consultation is free and without obligation.

Accountants for Uber Drivers – Are They Needed?

/in , , , , , , /by

Accountants for Uber Drivers – Are They Needed?

Are you an Uber driver? If so, you need to ensure that you submit an accurate self-assessment tax return each year and, with new rules and data sharing now in place, it’s never been more important to get your figures right. You may therefore be wondering whether you need an accountant. Today’s guide gives Uber drivers an overview of the main rules for complying with HMRC, what they need to supply, and how accountants like Taxfile can help drivers with accounting, bookkeeping and self-assessment tax returns each year. By getting these right, Uber drivers will minimise tax, keep on the good side of HMRC and fulfil their tax obligations. Doing so will also help them avoid a financial mess and, potentially, nasty penalties from HMRC.

Do Uber Drivers Need an Accountant?

As well as doing the job of driving, Uber drivers need to report their earnings and pay any taxes and National Insurance due to HMRC. This needs to be done accurately and on time in order to avoid HMRC penalties. This is more important than ever now because, since 1 January 2024, digital platforms like Uber will be legally required to report drivers’ income directly to HMRC. Professional drivers will therefore need to be 100% accurate in what they report and pay in terms of tax. Therefore, getting expert help from an Uber accountant is recommended — and the accountancy fees are tax-deductible.

“The regulations will support the government’s work to help taxpayers get their tax right first time, and to bear down on tax evasion.” (HMRC)

As part of the process, Uber drivers will need to submit an accurate self-assessment tax return each year. At the time of writing (July 2024), the next one they will need to file with HMRC is for the tax year 2023-24. The deadline is in January 2025 (or 3 months earlier if filing via the old-style paper tax return).

“Drivers remain self-employed for tax purposes and still have to complete an annual tax return.” (Uber.com)*

Tempted to Do Your Own Tax Return?

When Uber drivers log into their Uber account, they will have access to a tax report which shows their earnings and expenses. It may be tempting to use only this information to do their own Self-Assessment tax return. However, the information supplied via the Uber account will not include capital allowances on vehicles purchased and potentially many other claimable expenses like those that we highlight later in this guide. In other words, they could lose out — and pay more tax than they need to! That’s a major reason why employing an accountant like Taxfile makes sense for Uber drivers.

Taxfile: an Uber Driver Accountant in South London

Taxfile’s accountants and tax agents work with many professional drivers every year, including Uber drivers. We are therefore experts at working out income, expenses, National Insurance, income tax, and compliance with HMRC requirements and deadlines. This culminates in us submitting hundreds of self-assessment tax returns for drivers every year. For professional drivers working through digital platforms like Uber, we work out drivers’ income and help to reduce any tax liability by offsetting all eligible expenses. We also help drivers register for Self Assessment when they first start. This gives them a UTR number, which is needed in order to file a tax return.

What Expenses Can Uber Drivers Offset Against Tax?

There are several expenses that Uber drivers can potentially offset against income in order to reduce tax. As you might expect, many stem from the use of a vehicle for the business. Examples include:

  • The part of the driver fees paid to Uber;
  • Road tax;
  • The cost of MOT tests;
  • The cost of maintaining the vehicle e.g. servicing, cleaning and repairs;
  • Fuel costs/mileage (there are several different ways to approach this);
  • The cost of leasing or renting the vehicle;
  • Capital allowances on vehicles purchased;
  • Parking and any toll fees;
  • The cost of vehicle insurance;
  • Accountancy fees associated with running the business;
  • Bank loan interest;
  • Use of a phone, radio, and/or GPS system for the business;
  • Costs associated with marketing the business (advertising etc.);
  • And possibly additional costs not listed here.

Taxfile can advise on all of these to ensure that Uber drivers pay no more tax than they absolutely need to. Such expenses can usually be offset where they apply to business-related use (not personal). Uber drivers must keep comprehensive and accurate records, i.e. invoices and receipts etc., in order to claim.

So, if you are an Uber driver or are planning on becoming one, please get in touch with Taxfile. We’ll help to get you set up for Self-Assessment and subsequently work with you to ensure your figures are correct, your tax return is accurate, and that it is submitted to HMRC in good time before the deadline. By doing so, you’ll know your tax affairs are in order and be able to avoid any nasty HMRC penalties. With our help, you’ll pay no more tax than you need to. You’ll also get a more accurate picture of your finances and help avoid surprises that might otherwise adversely affect cash flow.

*Are Uber Drivers Employees, Workers, or Self-Employed?

In terms of employment status, Uber drivers in the UK are now legally classed as workers rather than self-employed contractors or employees. This follows a ruling by the UK Supreme Court in 2021 (∞), which gives them certain employment rights.

However, purely from a tax standpoint, Uber drivers are effectively self-employed, hence the requirement to submit a Self-Assessment tax return each year.

Do I Need to Register for Self-Assessment?

/in , , , , , /by

Do I Need to Register for Self-Assessment?

by Mohamed at Taxfile.

In today’s guide, we look at the rules around whether or not you need to register for Self-Assessment and submit a tax return to HMRC each year. Let’s take a look.

Reasons to Register for Self-Assessment

You generally need to register for a Self-Assessment tax return if your income isn’t taxed at the source, meaning the tax isn’t automatically deducted from your wages/salary. Here are some common scenarios where you would need to register for self-assessment:

  • You are self-employed — sole traders, freelancers, and consultants typically fall under this category.
  • You receive rental income — if you earn income from renting out a property, you need to register.
  • You have a high income — employees earning over £100,000 per year need to register as their tax calculations may become more complex. (From 2023-24 you are only required to register if your income is above £150,000).
  • You have other income sources — this includes income from abroad, dividends, and partnership profits.

If you are still unsure about registration, please contact HMRC or call Taxfile on 0208 761 8000.

Registering for UK Taxes is Important

Registering for UK taxes is important for a few reasons, as we’ll explain below.

Firstly, it helps you avoid penalties. If you don’t register for Self-Assessment when required, you could face penalties from HMRC. These can be significant, especially if you’ve been earning income for a while without registering.

Secondly, it helps to ensure accurate tax payments. By registering and filing a Self-Assessment tax return, you ensure you’re paying the correct amount of tax. Without it, you might underpay and owe interest, or overpay and have to wait for a refund.

Thirdly, it helps you stay legally compliant. In severe cases, failing to register and pay your taxes can lead to legal action, including prosecution.

Registering also helps you maintain good standing with the Government. Being registered with HMRC shows you’re taking your tax obligations seriously. This can also be important if you’re applying for credit, a mortgage, or a visa.

Do Directors Need to Do a Self-Assessment?

Not all directors need to do a Self-Assessment tax return, but some do. Here’s a breakdown:

Directors with only PAYE income

If your only income from the company is through PAYE (Pay as You Earn), where tax is deducted at source, you generally don’t need to do a Self-Assessment.

Directors with additional income

If you have any other taxable income besides your salary, like dividends, company benefits, or income from another job, you likely do need to do a Self-Assessment tax return in order to report it.

However, even if you aren’t required to register, HMRC might still ask you to file a Self-Assessment return.

Learn more about director self-assessment here.

Why is Payroll Important for a Director?

Payroll ensures compliance with tax regulations. Directors are considered employees for tax purposes, and PAYE is the system used to collect Income Tax and National Insurance Contributions (NICs) from their salary. Running payroll ensures these deductions are made and reported correctly to HMRC.

Payroll creates a clear and accurate record of your director’s salary payments. This is important for tax purposes, but also for things like calculating benefits and pension contributions that might be tied to salary.

Being on payroll allows directors to qualify for certain benefits they wouldn’t get if paid through dividends alone. These can include enrolling in a company pension scheme and accruing National Insurance credits that contribute to your state pension.

Payroll ensures transparency by helping to maintain a clear separation between personal finances and the company’s finances. This is important for legal and accounting reasons.

While there might be tax advantages to structuring some of your director’s income as dividends, payroll remains a vital part of ensuring you’re following regulations and have a clear record of your director’s overall compensation.

Filing with Companies House – A Guide for Limited Companies

/in , , /by

Filing with Companies House - A Guide for Limited Companies

Companies House is the Government agency responsible for maintaining the public register of companies in the UK. Filing with Companies House typically refers to the submission of various documents and records, as required by the registrar of companies in the United Kingdom. In today’s guide, we’ll take a look at what types of document need to be filed, when to file them, and what happens if they’re not filed on time.

What Sort of Documents are Filed at Companies House?

Some of the most common types of filings with Companies House include the following:

Annual Accounts

Most companies are required to file annual accounts, which include a balance sheet, profit and loss account, and notes to the accounts. The filing deadline for this varies and depends on when the company was set up.

A company gets nine months from its year-end in which to file the company accounts to Companies House and such a period helps in some ways. However, it also leaves the company’s accountants with little time to prepare and the directors with very little time to pay their Corporation Tax bill. Ideally, therefore, records should be with the accountant in the month following the company’s year-end rather than in the month the deadline falls — which is so often the case.

Confirmation Statement

The Confirmation Statement replaced the Annual Return in 2016. It confirms that information about the company held by Companies House is accurate and up to date. The Confirmation Statement must be filed at least once a year, even if there have been no changes to the structure of the company (e.g. changes to directors, shareholders, share capital etc.).

It is very important to update the Confirmation Statement when it is due. That’s because, if it becomes too overdue, Companies House is quick these days with a potentially severe punishment: a proposal to strike off the company.

Changes to Company Details

Any changes to the company’s details, such as changes to the registered office address, directorships, company name, or share structure, need to be filed with Companies House.

Special Resolutions and Share Allotments

Similarly, any significant changes to the company’s structure or decisions made by shareholders (such as issuing new shares or changing the company’s constitution) need to be filed with Companies House.

Incorporation Documents

When registering a new company, various documents such as the Memorandum and Articles of Association need to be filed with Companies House.

Once the company has been set up, the director of the company will receive an Authentication Code. This needs to be kept safe as it works like a PIN code and is used for filings with Companies House online.

Company Dissolution

Conversely, if a company is being dissolved (closed down), the necessary paperwork also needs to be filed with Companies House.

Filing requirements and deadlines can vary depending on the type and size of the company. Failure to file required documents accurately and on time can result in penalties and other adverse consequences for the company and its officers. It’s important, therefore, for company directors and secretaries to stay on top of their filing obligations with Companies House. By doing so, they should avoid the negative consequences associated with non-compliance with the law.

Guide to the Employer Payment Summary (EPS) – for Limited Companies within the CIS

/in , , , , , , , , , /by

Guide to the Employer Payment Summary (EPS) – for Limited Companies within the CIS

by Daniel at Taxfile.

Understanding the Employer Payment Summary (EPS) monthly claims for limited companies within the CIS

Limited company contractors operating within the Construction Industry Scheme (CIS) have distinct payroll obligations, including the submission of their Employer Payment Summary (EPS). In today’s guide, we’ll explain what the EPS is, its purpose, and the submission rules limited companies have to follow if they work within the Construction Industry Scheme.

What is the EPS?

The Employer Payment Summary serves as a crucial mechanism for limited company contractors to report additional payments, deductions, and adjustments to HM Revenue & Customs (HMRC) alongside their regular payroll submissions. While all such employers submit a monthly EPS, limited company contractors operating under CIS have specific considerations due to their status and the nature of their work within the construction industry.

The purpose of submitting monthly EPSs for Limited Company Contractors in the CIS

The primary purpose of EPSs for limited company contractors operating within the CIS is to provide HMRC with accurate information about deductions suffered under the Construction Industry Scheme. By submitting each monthly EPS for CIS, limited company contractors also ensure compliance with CIS regulations and provide HMRC with essential data for tax calculations and entitlements.

Submitting an EPS for Limited Company Contractors working within the CIS

Limited company contractors operating within CIS are required to submit an EPS to HMRC every month, even if there are no adjustments to report. EPSs should be submitted after the end of the tax month but before the 19th of the following month, in line with HMRC guidelines.

Contractors can use HMRC’s online services or compatible payroll software to submit their monthly EPS for CIS. It’s crucial to ensure that the information provided in each EPS accurately reflects the deductions suffered under CIS.

The CIS deductions suffered sent through an EPS are promptly reflected as a credit on the PAYE account. This credit will then be utilised to set off against other liabilities, including PAYE tax, National Insurance Contributions (NIC), and subcontractor’s tax submitted through the CIS300 return.

When sending the EPS you can also claim Employment Allowance and recover statutory payments that exceed the amount of PAYE due.

Submitting EPSs late may lead to penalties imposed by HMRC, which can vary based on the extent and frequency of delays.

CIS Contractor's Monthly Return (CIS300) - Explained

CIS Contractor’s Monthly Return (CIS300)

/in , , , , , , /by

CIS Contractor's Monthly Return (CIS300) - Explained

by Daniel at Taxfile.

The CIS Contractor’s Monthly Return is a mandatory requirement for contractors operating within the Construction Industry Scheme (CIS). It acts as a mechanism for contractors to disclose to HM Revenue and Customs (HMRC) payments issued to subcontractors and the corresponding tax deductions withheld from those payments. By providing HMRC with information regarding payments rendered and the accompanying tax deductions, the CIS Contractor’s Monthly Return guarantees transparency and adherence to regulations within the construction sector. In today’s guide, we explain the various components of the monthly ‘CIS300’ return, how the process works, key deadlines, the ramifications of non-compliance, and much more.

Key Components of the Monthly Return

The CIS Contractor’s Monthly Return typically includes the following key components:

This section includes information about the contractor, such as their name, Unique Taxpayer Reference (UTR), and contact details. Ensuring accuracy in this section is crucial for HMRC’s records and communication purposes.

Contractors must provide details of all subcontractors they have engaged during the reporting period. This includes the subcontractors’ names, UTRs, and payment amounts.

Contractors must report the total payments made to each subcontractor during the reporting period. This information helps HMRC track payments within the construction industry and verify compliance with tax obligations.

Contractors are required to calculate and report the tax deductions made from payments to subcontractors. The deducted amounts are typically based on the subcontractors’ verification status and tax treatment under the CIS.

The Monthly Return concludes with the calculation of the total amount due to HMRC, taking into account the tax deductions made from payments to subcontractors.

Deadlines and Reporting Periods

The CIS Contractor’s Monthly Return deadlines follow a structured timeline, which includes:

  • The submission deadline — contractors must submit their Monthly Returns to HMRC by the 19th of each month following the end of the reporting period. (Contractors’ payments to HMRC must also be made by this date).
  • The reporting period covered by each Monthly Return — which typically spans from the 6th of the previous month to the 5th of the current one.

Making Your CIS Payments to HMRC

Once you’ve calculated the total CIS deductions, prepare to make the payment to HMRC. You will need to have the following information ready:

  • Your Unique Taxpayer Reference (UTR) number;
  • Your payment reference, which is your 13-character Accounts Office reference number followed by the letter ‘C’ (e.g., 123PA12345678C);
  • The amount you’re paying.

HMRC offers various payment options for settling your CIS liabilities, which are explained here.

  • A contractor who operates as a limited company and also acts as a subcontractor might find that they are exempt from making any payments to HMRC. Subcontractors who do not have gross payment status will incur CIS deductions, which can then be used to offset any CIS payments owed to HMRC. This is exclusively available to limited companies. Please look out for our forthcoming blog focused on the CIS claim — a hyperlink will follow here once it’s live.

Implications of Non-Compliance

Failure to meet CIS Contractor’s Monthly Return deadlines can lead to various consequences, which may include the following:

  • Penalties — HMRC may impose penalties for late or non-submission of Monthly Returns, which can escalate over time.
  • Loss of benefits — non-compliance with CIS obligations, including Monthly Return deadlines, can lead to loss of benefits such as gross payment status, affecting contractors’ cash flow and competitiveness.

Managing the CIS Monthly Return Process

For contractors, efficiently managing the CIS Contractor’s Monthly Return process involves the following steps:

1. Maintain Accurate Records

Contractors should maintain accurate records of payments made to subcontractors and tax deductions applied. This includes keeping track of invoices, receipts, and CIS statements.

2. Timely Submission

The Monthly Return must be submitted to HMRC by the 19th of each month following the end of the reporting period. Contractors should ensure timely submission to avoid penalties and maintain compliance.

3. Use HMRC Online Services

HMRC provides online services for submitting CIS returns, making the process convenient and accessible for contractors. Registering for and using these online services can streamline the submission process and reduce administrative burdens.

The CIS Contractor’s Monthly Return is the key tool through which to report payments and tax deductions accurately to HMRC. Understanding its components and effectively navigating the submission process helps to ensure that contractors are compliant — and also avoids unnecessary penalties.

Rest assured, though: Taxfile is here when you need help with CIS returns and accountancy for construction workers, bookkeeping, CIS tax rebates for subcontractors, limited company accounts, and any tax-related matters that require professional help. We’re happy to provide guidance on compliance requirements, tax calculations, record-keeping practices, and much more.
