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) - 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.

Setting Up for Making Tax Digital - Bookkeeping, Record-Keeping Etc

Setting Up for Making Tax Digital

Setting Up for Making Tax Digital - Bookkeeping, Record-Keeping Etc

by Sue at Taxfile.

Whether you’re new to self-employment and have just started to run your own business, or have been doing it for a while – the fact is: Making Tax Digital (‘MTD’) is coming and it would be best to get set up in the right way, now.

Record-Keeping for Making Tax Digital

Keeping your personal life & your business completely separate is the best policy. It keeps things streamlined and will also save you money when your tax agent comes to do your bookkeeping & tax returns. So:

  • Set up a separate bank account just for your business;
  • Pay for your expenses from this account;
  • Pay income from your sales into it;
  • Keep an ongoing file for each tax year, where you put all your expenses, receipts & invoices;
  • Include copies of your sales invoices in that file too;
  • Keep the file in monthly order, so that accountants/tax advisors like Taxfile can easily cross-check the invoices to the bank statements and analyse your costs accurately.

Setting Up Digitally

Making Tax Digital means that you must run your business through a digital traceable source. The best way to do this is to allow us, if we are your tax agent/accountant, to set up your bank statements to feed automatically into accounting software like ‘Xero’. Alternatively, we can accept bank statements downloaded in CSV format, which we would then transfer to Excel spreadsheets.

Cash & Card Sales

If you are making cash & card sales, set up an app on your smartphone like ‘Sum Up’ or ‘Square’ so that you will be complying with MTD – your bank can also supply you with a PDQ card reader to accept your cash/card sales. We can upload your sales reports from these services and include them in your sales figures.

Accurate record-keeping is the cornerstone of every successful business

Moving to Quarterly Reporting

Here at Taxfile, we can currently run your bookkeeping for you quarterly or annually. However, when HMRC implement MTD fully in 2026, tax returns will need to be submitted each quarter — no longer just once a year. We’re therefore recommending that everyone gets used to sending in their bookkeeping records quarterly.

Quarterly bookkeeping also allows us to monitor your sales turnover and alert you at the appropriate time if you are approaching the level of sales that would require you to get registered for VAT. Finding out at the end of the year that you have already gone over the threshold — and should have been charging VAT at an earlier date — can be very costly.

C.I.S. Subbies: claim your refund for Christmas!

CIS Construction workers get a tax refund in time for Christmas![UPDATED]: Calling all subbies! Claim your refund in time for Christmas AND get a 5% discount on Taxfile prices if you submit your records to us before 21st December!

If you’re a sub-contractor working in the UK construction industry, the first thing you should do is register for CIS (the Construction Industry Scheme). This gives you your own unique tax reference and you effectively become self-employed from a tax standpoint. Taxfile can help set you up on the CIS system (we charge just £36 + VAT for this at time of writing).

Once enrolled, any earnings will automatically be taxed, at source, at 20%. However, with the personal allowance being set at around £10,600 per annum in most cases, this means that many subbies will have overpaid tax and will be due a refund at the end of the tax year. Taxfile are experts at recovering this type of tax for construction workers. We can analyse income, offset any applicable expenditure and allowances, work out the correct National Insurance and income tax, then submit an accurate tax return. 9 out of 10 subbies using Taxfile receive a tax refund within 3 to 4 weeks, many of those receiving in excess of £1000. Taxfile do more than 500 of these annually and Read more
