Stay Ahead of HMRC Compliance Checks for CIS Contractors

Stay Ahead of HMRC Compliance Checks for CIS Contractors

By Ali at Taxfile.

As the new tax year approaches, CIS contractors must prepare for the upcoming 2024/25 tax return season.  Last year we witnessed a significant increase in HMRC compliance checks delaying refunds, with many contractors being asked to provide detailed CIS pay/deduction slips and bank account transactions to verify their income.

At Taxfile, we are here to help you navigate these challenges and ensure your tax affairs are in order while offering you peace of mind with our unique HMRC investigation cover.

Why Are HMRC Compliance Checks on the Rise?

HMRC has ramped up its efforts to ensure compliance among CIS contractors, particularly focusing on verifying income and deductions. Last year, many contractors were caught off-guard when asked to provide:

  • CIS pay/deduction slips to confirm tax deductions at source.
  • Bank account transactions to prove income received from contractors.

Failure to provide these documents can lead to penalties, delays, and even full-scale investigations. With HMRC’s increased scrutiny, it’s more important than ever to ensure your records are accurate, complete, and readily available.

At Taxfile, we specialise in supporting CIS contractors with their tax returns and compliance needs.

How we stand out:

1. Expert Preparation of CIS Tax Returns

Our team ensures your 24/25 tax return is accurate, compliant, and submitted on time. We review your CIS pay/deduction slips, income, and expenses to minimise the risk of errors that could trigger an HMRC compliance check.

2. HMRC Investigation Cover is Included

Unlike other accountancy services, our invoices include HMRC investigation cover as standard. If HMRC decides to investigate your tax return, we’ll handle all the additional work required to represent you—at no extra cost. This means you’re protected from unexpected fees and stress.

3. Proactive Record-Keeping Support

We guide you on how to maintain proper records, including CIS slips, bank statements, and expense receipts, so you’re always prepared for an HMRC request.

4. Dedicated CIS Specialists

Our team understands the unique challenges faced by CIS contractors. We’re here to answer your questions, provide tailored advice, and ensure you’re fully compliant with HMRC regulations.

With HMRC’s increased focus on compliance, now is the time to act to ensure you get your refund sooner. We urge you to come prepared with your CIS deduction slips and your bank feed covering the period from 06/04/2024 – 05/04/2025.

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 Contractor's Monthly Return (CIS300) - Explained

CIS Contractor’s Monthly Return (CIS300)

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.

How we harness technology at Taxfile in Tulse Hill & Dulwich, South East London

The rapid pace of technological change has caused some of the biggest shifts in how we view and process our tax returns. At Taxfile, we’re constantly striving to use technology as effectively as possible to aid us in collecting, analysing, and collaborating when working on your personal data.

Over the pandemic, we’ve had to place our reliance even further on technology to maintain our standards, with regular meetings online. We’re constantly improving the efficiency of our work pipeline and, with the ability to pull figures directly from online bank statements, we can ensure precision in the numbers we present you with. For the last two years, we’ve implemented cloud technology as both a collaborative tool between our senior and junior staff and as storage for various databases used to track everything from employee working hours to the status of your tax return. We’re expanding further on this concept in collaboration with Pure Technology by merging our existing cloud systems with our current remote work solution to form one, all-encompassing workspace environment. Hosting it in the Microsoft Cloud ensures that, with the help of our office staff, your paperwork and bookings can be sent to and viewed by your tax agent as soon as possible. This and a variety of other endeavours are examples of our ambitions to be at the forefront of innovations, and constant review of our policies ensures we remain ahead, or on track, to meet the standards set by Making Tax Digital (MTD) for its 2023 launch.

Domestic Reverse Charge for the Construction Sector

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

The Domestic Reverse Charge (DRC) for the construction sector comes into effect as of 01/03/2021.

What does this mean for you?

If you are VAT registered & you work falls under the Construction Industry Scheme (CIS) then from the 1st of March you will need a written declaration from your contractor that they are classified as an end user.

An end user simply put is the land owner or an intermediary company with a direct link to the land owner.

If they are classified as the end user then nothing changes and VAT will be paid to you to then declare on your VAT returns.

However, if you are not working for the end user, the VAT will not be paid to you and it will be your contractors responsibility to declare the VAT from your invoice to HMRC.

If you are on a flat rate scheme and some or all your work falls under the DRC then we advise you to consider writing to HMRC and cancelling your flat rate scheme for VAT.  If the majority of your work is not for the end user, then most definitely do this immediately or call us and we can advise you.

If you need help understanding the DRC and how it applies to you then please do not hesitate to contact us on 020 8761 8000.

At Taxfile we specialise in the construction sector, calculating and submitting Making Tax Digital (MTD) compliant VAT returns for numerous sole traders and limited companies.  If you are looking for an accountant to manage your MTD VAT returns, then we can help you.

Further Delays on the Roll-Out of the Domestic Reverse Charge for the Building & Construction Services.

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

The domestic reverse-charge is a major change to the way VAT is collected by HMRC in the building and construction industry reporting under the Construction Industry Scheme (CIS).

It was being introduced to combat VAT fraud in the sector and the initial roll-out on 1st October 2019 was delayed due to a combination of the sector being ill-prepared for the change and Brexit. The date was moved forward 12-months to 1st October 2020 but due to COVID-19 the start date has been further advanced to 1st March 2021.

At Taxfile, we will start contacting our VAT clients working under the CIS, in preparation for the 1st March 2021 start date.

Tax Returns for Self-Employed Londoners - Special Offer

Tax Returns for Self-Employed Londoners – Special Offer!

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

Tax returns for self-employed Londoners - Special Offer!
Are you self-employed? Are you late filing your 2018/19 Self-Assessment tax return? If so, now is the time to get Taxfile to sort it out for you.

There are 4 important reasons why you should file your tax return now:

1. Save money, with our special offer!

For a very limited time, we are offering to do 2018-19 Self-Assessment tax returns for self-employed Londoners for just £199 + VAT (our usual pricing is from £277 + VAT). That’s a saving of nearly £94 including VAT.

2. Stay eligible for Government Help during the lock-down

Self-employed people who are struggling financially during the coronavirus lock-down may be eligible for financial help from the Government. This is in the form of their recently announced Self-Employed Income Support Scheme (‘SEISS’). However, to remain eligible, you must have filed your 2018/19 Self-Assessment tax return by 23 April. If you miss that deadline, you will no longer be eligible for that Government assistance.

3. Avoid severe fines from HMRC for being so late

The original deadline for submission of your 2018/19 Self-Assessment tax return was actually 31 January 2020. So, if you didn’t already file your tax return by that date, you already owe HMRC a fine of £100 minimum. That’s nothing, though, compared to the penalties they will start charging you after April. From 1 May, you will owe an additional £10 per day, every day from that date if you still haven’t filed your 2018/19 tax return. So, for example, after a week you’ll owe the original £100 plus an additional £70 as a minimum, or the £100 plus a further £140 after two weeks and so on. You may also be charged interest on top of all of that if you owed HMRC a tax payment on the original 31 January deadline and still haven’t paid it.

4. You may be due a tax rebate

Some self-employed people may be due a tax rebate. This depends upon your
