Builders across the UK are noticing the same thing: HMRC seems stricter than ever. More letters, more questions, more requests for records, and less patience for missing paperwork. Even builders who have been working for years without issues are now being asked to prove income, expenses, and subcontractor payments in more detail.
This increase in attention isn’t always personal. Construction is a fast-moving industry with high cash flow, subcontractor networks, and frequent CIS activity. That makes it a sector where mistakes happen easily, even when a builder is doing honest work.
That’s why accountants for builders are becoming more important than ever. Good accounting doesn’t just “help with taxes.” It helps builders stay organised, reduce risk, and respond confidently if HMRC asks questions.
In this article, we’ll explain why builders are facing more HMRC checks, what triggers them, and how the right accounting support protects your business.
Why HMRC Pays Close Attention to the Construction Industry?
Construction is one of the busiest industries in the UK, but it’s also one of the most complex from a tax point of view. Payments move quickly, labour is often subcontracted, and expenses can be difficult to track properly.
HMRC focuses on construction because:
- CIS reporting happens monthly
- Subcontractor payments are common
- Labour and materials must be split correctly
- Cash payments still exist in parts of the industry
- Record keeping is often inconsistent due to site work
Even small errors can create mismatches in HMRC systems. That’s when a check or enquiry becomes more likely.
This is exactly where accountants for builders help. They set up records in a way that matches HMRC expectations, so you don’t look “messy” on paper.
The Biggest Triggers That Lead to HMRC Checks for Builders
HMRC doesn’t always explain why they ask for information, but there are common patterns that increase the chance of getting flagged. Many builders don’t realise they are creating risk until it’s too late.
CIS returns filed late or with incorrect details
CIS is a major trigger because it runs monthly. Late returns can lead to automatic penalties. Incorrect subcontractor details can also cause problems.
If you pay subcontractors, you must:
- verify subcontractors
- Apply the correct deduction rate.
- Submit monthly returns
- Provide payment statements
Accountants for builders often manage CIS returns or create a process so you don’t miss deadlines.
Inconsistent income reporting
Builders may get paid by different contractors, agencies, and private customers. If your reported income doesn’t match what HMRC expects based on CIS records or bank activity, it can trigger questions.
A good accounting system ensures your income is:
- recorded in full
- categorised correctly
- supported by invoices or job records
This is where accountants for builders protect you by helping you claim correctly and store evidence properly.
CIS Mistakes: The Most Common Reason Builders Get Stressed
CIS is not optional if you’re operating in the construction supply chain. Many builders think CIS is only for “big contractors,” but even smaller building businesses can fall under CIS rules depending on what work they do and who they pay.
The pressure comes from the fact that CIS involves:
- monthly deadlines
- labour/material splits
- subcontractor verification
- correct deduction calculations
Real-world example
If you pay a subcontractor £1,500 and don’t verify them, you may deduct at the wrong rate. That can cause issues for both you and the subcontractor later, especially if HMRC asks for explanations.
Specialist accountants for builders help avoid this by keeping CIS reporting clean and consistent.
Choosing Accountants for Builders: What to Look For
Not all accountants understand construction. A general accountant may be good with basic returns, but builders need someone who understands CIS, subcontractors, and job costing.
When choosing accountants for builders, look for:
- experience with CIS returns and verification
- clear guidance on allowable expenses
- VAT knowledge, including reverse charge rules
- support with bookkeeping software
- practical advice in plain English
- reminders for deadlines and compliance

FAQs:
-
Why are builders more likely to be checked by HMRC?
Construction involves CIS, subcontractors, and frequent payments, which increases the chance of reporting errors. HMRC monitors the sector closely, so builders are more likely to receive compliance checks.
-
What records should builders keep for HMRC?
Builders should keep invoices, receipts, bank statements, CIS statements, subcontractor details, mileage logs, and VAT records (if registered). Digital records are acceptable if they are clear.
-
Can HMRC check a builder’s bank account?
HMRC can request evidence and ask for bank statements during an enquiry. This is why separating business and personal spending is important.
-
What happens if a builder submits CIS returns late?
Late CIS returns can lead to automatic penalties. Repeated late submissions can increase the chance of further HMRC attention.
Conclusion
Builders are facing more HMRC checks because construction accounting is complex and mistakes are easy to spot through CIS and VAT systems. Even honest builders can get pulled into stressful situations if their records are incomplete or inconsistent.
