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.

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

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 Accountancy Help from Taxfile

At Taxfile, we can provide guidance on compliance requirements, tax calculations, and record-keeping practices.

Get in touch today for any accountancy or tax issue that needs expert help.


We can help whether you are a contractor, subcontractor, sole trader or limited company business in South London.

We are accountants in Tulse Hill, and Dulwich.

Forming a Limited Company?

Having been the accountants of choice for individuals and businesses in the South London area, we have recently noticed a surge of individuals moving away from the sole trader status and enquiring about forming a limited company.

The reasons for changing status have varied; someone mentioned they should be, their customers needing them to be, being worried about having a personal liability against the business, to hoping to be more tax efficient.

What do we mean by a limited company?

A limited company is an organisation that is set up to run your business. A business becomes ‘limited’ once the company name and its owner(s) have been registered with Companies House and when limited status is granted, it becomes a distinct entity from its owners.

A limited company structure creates a distinct border between the business owner and the business itself, and under the eye of law, the business becomes a separate legal entity in its own right, becoming responsible for its own actions and finances.  This in turn limits the liability of the owner from any risk the business may need to take.    So if you are a small business expanding & possibly needing employees & assets, then a limited company is a good idea.

At Taxfile we are helping a lot more clients make this transition from a sole trader to limited status.

We can help you set up a private limited company, guide your through the process of what happens and what you need to do.  We offer an all-encompassing service from the setting up to filing the corporation tax returns.

We are offering a special price of £375+VAT for the following;

  • company formation (including the option to have the company phrased as a special purpose vehicle for a property rental company- SPV)
  • we will register a single director with HMRC for self-assessment
  • we set up the payroll scheme
  • we arrange your chart of accounts on online software and set up the bank feed so transactions are automatically recorded

A limited company will:

  • need to keep company records
  • report any changes to Companies House & HMRC
  • need to file an annual company tax return along with the company’s accounts, giving an undistorted view of its finances.

As a director of a private limited company you will:

  • make decisions that benefit the company rather than yourself
  • abide by the rules and regulations outlined by the company articles of association, which are written rules about running the company agreed by the shareholders or guarantors, directors and the company secretary
  • notify any shareholders if you might benefit personally from a company transaction
  • always act with the intention of making the company successful.
  • In forming a limited company you are limiting your personal liability but in doing so you cannot abuse your power with the limited liability to take selfish and unnecessary risks.

At Taxfile we can advise you on setting up a private limited company and take care of all these tasks for your private limited company — and avoid any complications down the line.

Starting a limited company is a relatively straightforward administrative task that starts out with choosing an available company name from Companies House to filling and filing a series of forms. At Taxfile we can ensure that all your forms are compiled correctly, providing ongoing support.

To set up your private limited company you will need at least one director and one shareholder.  As the business owner(s) you would then take a salary/wage from the business.  We can advise you how to best set up your salary and dividends to pay less tax.

Once you have a limited company set up you will need to open a new bank account in the name of your new company.  Our advice to clients, is to try and keep all the business income and expenses restricted within this one bank account and to avoid any personal transactions overlapping into this account.

It is also important to remember to transfer all business-related expenses into the company’s name and move any payment plans over to the new bank account.

New 30-Day Rules for Capital Gains on Residential Property

New 30-Day Rules for Capital Gains on Residential Property

New rules have now come into force in relation to capital gains made on disposals of UK residential property*. Several key actions are now required if a taxable capital gain has arisen, including some that now need to be made fast:

  1. Taxpayers need to report the property’s disposal within 30 days of the actual disposal;
  2. They will need to pay the estimated Capital Gains Tax (‘CGT’) to HMRC within 30 days of the disposal.
  3. Those who fill in and submit a Self-Assessment tax return will also need to include details of the disposal on their return.

Who Do the New CGT Rules Apply To?

The new rules apply whether you’re an individual, joint property owner, trustee, partner in a partnership or LLP, or a personal representative.

What Counts as a Residential Property Disposal?

The new rules apply to all UK residential property that was disposed of (taken as the date of the exchange of contracts) since 6 April 2020 inclusive, where a capital gain was made that will require payment of CGT.

To fall within the rules, a UK residential property must be one that:

  • is suitable for use as a dwelling, or;
  • is being built or adapted for use as a dwelling.

It can be one in which the the owner has never lived or has lived for only part of the period they owned it. It can also be a rental property or a holiday home.

Where a property has been used for mixed purposes, only the capital gain that’s equivalent to Read more
