At Towerstone Accountants we provide specialist CIS accountancy services for contractors and construction businesses across the UK. We created this webpage for subcontractors and contractors who want clear guidance on the Construction Industry Scheme, including registration, deductions, refunds, and ongoing reporting obligations. Our aim is to help you stay compliant with HMRC, avoid costly errors, and understand how CIS affects your tax position.
One of the most common frustrations I hear from subcontractors is not knowing exactly what has been deducted under CIS, whether it has been reported correctly, or if HMRC actually holds the right figures. People often assume that once tax is taken off their payments it simply disappears into the system and will somehow sort itself out at the end of the year. In reality, checking your CIS payments online is one of the most important habits you can build if you work in construction, because it gives you visibility, control, and confidence over your tax position.
Over the years, running my own accountancy firm and dealing with large numbers of CIS clients, I have seen how small errors go unnoticed for months or even years simply because no one checked the figures online. I have also seen how empowering it is for people when they understand where to look, what they are checking, and how those numbers flow through to their tax return.
In this article, I am going to explain how to check CIS payments online, what information you can see, what you should be comparing it against, and what to do if something does not look right. I will also explain the difference between what subcontractors see and what contractors report, because that distinction matters more than most people realise.
By the end of this guide, you should feel confident navigating your CIS information online and using it properly rather than hoping everything lines up at the end of the tax year.
Why Checking CIS Payments Online Matters
CIS works on the principle that tax is deducted at source and credited to you in advance. That only works properly if the deductions reported by contractors match what HMRC has on record and match what you include on your tax return.
When you check your CIS payments online, you are effectively checking three things at once, whether contractors have reported your income correctly, whether the deductions match what was taken from your invoices, and whether HMRC is holding the right figures against your record.
If something is wrong and you do not spot it early, it can cause problems later. I have seen cases where deductions were never reported, where income was reported twice, and where details were linked to the wrong person or company. All of these issues are far easier to fix when they are identified early rather than years down the line.
Who Can Check CIS Payments Online
If you are a subcontractor registered under CIS, you can check your CIS payment information online. This applies whether you are a sole trader, a partnership, or a limited company subcontractor.
Contractors also have online access, but they see a different side of the system. Contractors use their CIS online account to submit monthly returns, verify subcontractors, and report deductions. Subcontractors use their account to view what has been reported about them.
Understanding which role you are acting in is important, because people sometimes log into the wrong account and assume information is missing when it is actually held elsewhere.
What Information You Need Before You Start
Before checking CIS payments online, you need access to your Government Gateway account. This is the same system used for Self Assessment, PAYE, and other HMRC services.
For individuals, you will usually need:.
Your Government Gateway user ID and password
Your Unique Taxpayer Reference
Your National Insurance number
For limited companies, you will need access to the company’s Government Gateway account, not your personal one, and the company UTR.
This distinction matters, and I regularly see directors log into their personal account and wonder why CIS figures are not showing for the company.
How to Check CIS Payments Online as a Subcontractor
Once logged into your Government Gateway account, you can access your CIS information through your tax account. If you are a sole trader, this is usually found within your Self Assessment area.
Inside the CIS section, you can view payments and deductions reported by contractors. The information is normally broken down by tax year and often by contractor.
You should be able to see:.
The gross amount paid
The amount of CIS tax deducted
The contractor who reported the payment
The tax month or period it relates to
This information comes directly from the monthly CIS returns submitted by contractors. If a contractor has not submitted a return, or has submitted incorrect details, it will show up here as missing or inaccurate information.
Timing and Delays in CIS Reporting
One thing I always explain to clients is that CIS information online is not always instant.
Contractors submit CIS returns monthly, usually by the 19th of the following month. HMRC then processes that information before it appears on your online account.
Because of this, there can be a delay between being paid and seeing the figures online. This is normal, but it does mean you should not panic if the most recent payment is not visible immediately.
That said, if several months are missing, or figures never appear, that is a sign something may be wrong and should be investigated.
Comparing Online CIS Figures to Your Own Records
Checking CIS payments online only really works if you compare it to your own records. This is where good bookkeeping makes a real difference.
You should be keeping copies of invoices issued, payment receipts, and CIS deduction statements provided by contractors. When you check your CIS payments online, you should be comparing:.
The gross income reported online to your invoices
The deductions shown online to your CIS statements
The total figures for the tax year to your bookkeeping records
If everything matches, that is reassuring. If it does not, it is a prompt to investigate further.
CIS Deduction Statements and Online Records
Contractors are required to provide subcontractors with CIS deduction statements, usually monthly. These statements show how much has been paid and how much tax has been deducted.
In an ideal world, the figures on these statements should match what appears online. In practice, I often see discrepancies, especially where contractors use manual systems or submit late returns.
If the statement says tax was deducted but nothing appears online, it may mean the contractor has not filed the return correctly. That tax may not be credited to you unless it is reported properly.
What to Do If CIS Payments Are Missing Online
If you notice that CIS payments or deductions are missing from your online account, the first step is not to panic.
Start by checking your own records and confirming which payments are missing and which contractor they relate to. Then speak to the contractor and ask whether the CIS return has been submitted and accepted.
In many cases, the issue is simply a late or corrected return. Contractors can amend CIS returns if mistakes have been made, but this only happens if the issue is flagged.
If the contractor cannot resolve it, or if the issue persists, this is where professional advice can help, because HMRC will usually require evidence before making any manual adjustments.
Checking CIS Payments Online for Limited Companies
For limited companies, checking CIS payments online works in a similar way but must be done through the company’s HMRC account.
Once logged in, you can view CIS deductions suffered by the company. These figures are particularly important because they are often offset against PAYE liabilities or reclaimed through the company’s accounts.
I often see companies miss CIS deductions simply because no one checked the online account and the figures were never included in the bookkeeping. That can mean overpaying tax unnecessarily.
How CIS Payments Feed Into Your Tax Return
Understanding how CIS payments flow into your tax return helps make sense of why checking them online matters so much.
For sole traders, the total CIS deductions shown online should be included on your Self Assessment return. These deductions are offset against Income Tax and National Insurance.
If the deductions exceed your tax liability, a refund may be due. If the deductions are missing or understated, you may end up paying tax you do not actually owe.
For limited companies, CIS deductions are usually offset against PAYE liabilities or reclaimed. Again, missing figures mean lost cash.
Common Problems I See When Checking CIS Payments
There are certain patterns I see repeatedly.
Contractors submit returns late or not at all
Details are reported under the wrong UTR
Payments are duplicated or omitted
Directors check personal accounts instead of company accounts
Figures are not reconciled before tax returns are submitted
Most of these issues only come to light when someone actively checks their CIS payments online.
How Often You Should Check CIS Payments Online
In my experience, checking CIS payments online should not be a once a year task.
Ideally, subcontractors should review their CIS figures every few months, or at least before providing information to their accountant for the tax return. Contractors should also regularly review their submissions to ensure accuracy.
Regular checks mean problems are caught early, when they are easier to fix and less stressful.
CIS Payments Online and Cash Flow Planning
Another benefit of checking CIS payments online is better cash flow awareness.
Because CIS deductions are tax paid in advance, knowing how much has already been deducted helps you understand whether you are likely to owe more tax or receive a refund. This makes planning far easier, especially for sole traders who need to budget carefully.
I often find that clients who check their CIS payments regularly feel far more in control of their finances and far less anxious about tax bills.
Final Thoughts
Checking CIS payments online is not just an administrative task, it is a key part of managing your tax position properly if you work in construction.
In my experience, the people who struggle most with CIS are not those who earn the least or do the most complex work, but those who never check what is being reported in their name. Once you get into the habit of reviewing your CIS information online and comparing it to your own records, most of the uncertainty disappears.
If something does not look right, the sooner it is identified, the easier it is to fix. And if you are ever unsure what you are looking at or how it should be treated, getting advice early can save a significant amount of time, money, and stress later on.
