Common Mistakes on Cheap CIS Tax Returns
Filing your own CIS tax return under the CIS scheme may seem straightforward, but many subcontractors make avoidable mistakes that result in penalties or missed refunds.
Failing to Record All Income Accurately
One of the most common problems with CIS tax returns is not recording all income correctly. If you have multiple contractors paying you, each may be deducting CIS tax separately. Failing to consolidate all payments before submitting your return can result in HMRC calculating incorrect totals, leading to underpayment penalties or delays in processing your refund. Our Cheap Tax Returns for CIS service ensures all income is included and verified before submission.
Missing Out on Allowable Expenses
Many CIS subcontractors overpay tax every year simply because they do not claim all their allowable expenses. From tools and materials to travel and workwear, these deductions can significantly reduce your tax liability. Without proper accounting knowledge, it is easy to overlook expenses that are fully compliant under HMRC rules. We make sure your CIS Tax Returns in London covers every legitimate expense so you keep more of your money.
Late Filing and Payment of Taxes
One of the biggest tax risks for CIS subcontractors is submitting the return after the deadline. Late filing results in automatic fines, daily penalties, and interest charged on outstanding balances. Contractors working on multiple sites often lose track of filing dates without professional support. Our Cheap Tax Returns for CIS service keeps you ahead of every HMRC deadline — so penalties are never a problem.

What Are Cheap CIS Tax Returns and Who Needs to File One?
CIS stands for Construction Industry Scheme. It is a system introduced by HMRC that requires contractors to deduct money from a subcontractor’s payments and pass it directly to HMRC as an advance payment toward the subcontractor’s tax and National Insurance contributions. If you are a self-employed worker or sole trader operating within the construction industry — whether you are a plumber, electrician, carpenter, plasterer, roofer, or general labourer — you are most likely working under the CIS scheme.
As a CIS subcontractor, you are required to file a Self Assessment tax return every year to report your income, claim back any overpaid CIS deductions, and declare any additional earnings. Many subcontractors have too much tax deducted throughout the year, which means they are entitled to a CIS tax refund from HMRC. Our Cheap CIS Tax Returns service ensures your return is filed accurately, on time, and with all eligible expenses claimed — so you get back every pound you are owed without overpaying a penny.
How Much Can I Claim Back With a CIS Tax Return?
The amount you can reclaim through a CIS tax return depends entirely on how much tax was deducted from your payments throughout the tax year and how many allowable expenses you can legitimately claim against your income. CIS deductions are usually made at 20% for registered subcontractors or 30% for those who are not registered with HMRC. In many cases, these deductions add up to significantly more than your actual tax liability — meaning you are owed a refund.
For example, if a contractor deducted £4,000 from your payments over the course of the year, but after claiming your allowable expenses your actual tax bill works out to only £1,500, HMRC will refund you the £2,500 difference. The more legitimate expenses you claim — such as tools, materials, travel, workwear, insurance, and phone costs — the lower your tax liability becomes and the higher your refund will be. Our team carefully reviews every expense category to ensure nothing is missed, helping you maximise your CIS refund legally and compliantly.
What Expenses Can CIS Subcontractors Claim on Their Tax Return?
One of the most important parts of filing a CIS tax return is claiming all the allowable expenses you are entitled to. Many subcontractors either miss expenses entirely or are unsure what they can legitimately claim, which results in them overpaying tax every single year. As a CIS subcontractor, you are allowed to deduct any expense that is incurred wholly and exclusively for the purpose of your work.
Common allowable expenses for CIS workers include the cost of tools and equipment purchased for work, materials used on jobs that you personally sourced and paid for, travel costs between different job sites (excluding your regular commute from home), work clothing such as safety boots, hi-vis jackets, and protective gear, public liability and professional indemnity insurance premiums, mobile phone and internet costs used for business purposes, accountancy fees including the cost of having your CIS tax return prepared, and any training or certification costs directly related to your trade. Our Cheap CIS Tax Returns service includes a full expense review as standard — we go through your records with you to make sure every legitimate deduction is included before your return is submitted to HMRC.
What Happens If I Miss the CIS Tax Return Deadline?
Missing the HMRC Self Assessment deadline is one of the most costly mistakes a CIS subcontractor can make, and unfortunately it is also one of the most common. The deadline for filing your online Self Assessment tax return is 31 January following the end of the tax year. If you miss this date, HMRC will automatically issue a £100 late filing penalty — even if you have no tax to pay or are actually owed a refund.
If your return remains outstanding beyond three months, additional daily penalties of £10 per day begin to accumulate for up to 90 days, meaning a further £900 in fines. After six months, HMRC charges an additional penalty of either £300 or 5% of the tax due — whichever is higher. After twelve months, a further penalty of the same amount is applied. On top of filing penalties, interest is also charged on any outstanding tax owed from the payment deadline. The good news is that it is never too late to get your CIS tax return sorted. Our team regularly helps subcontractors catch up on late or overdue returns, liaise with HMRC on their behalf, and minimise any penalties where possible. The sooner you act, the better the outcome.
Do I Need an Accountant to File My CIS Tax Return, or Can I Do It Myself?
Technically, you can file your own CIS Self Assessment tax return directly through HMRC’s online portal without using an accountant. However, the reality is that most CIS subcontractors who file their own returns either miss out on significant refunds, make errors that lead to HMRC penalties, or both. The Self Assessment system can be confusing, particularly when it comes to correctly recording CIS deductions, calculating allowable expenses, and ensuring your figures match what your contractors have reported to HMRC.
Using a professional accountant does not have to be expensive. A small fee that typically pays for itself many times over through the additional refund we secure by identifying expenses you may not have claimed yourself. Beyond the financial benefit, using our service saves you significant time, removes the stress of dealing with HMRC directly, and gives you the peace of mind that your return has been prepared accurately and submitted on time. For most CIS subcontractors, the cost of getting it wrong far exceeds the cost of getting professional help.
