04.CIS Questions Answered
Everything you need to know about CIS filing with A.X.E.L
CIS (Construction Industry Scheme) is HMRC's system for taxing subcontractors in construction. If you're a contractor who pays subcontractors, you must register with HMRC and file monthly CIS300 returns — even if you had no payments that month. This applies regardless of your turnover.
We're currently pending HMRC recognition. A.X.E.L is designed to meet HMRC's technical standards for MTD-compliant software. Once recognised, you'll be able to file directly through the platform. Until then, you can use A.X.E.L to prepare your returns and export them for manual submission.
Making Tax Digital (MTD) is HMRC's push to digitalise tax filing. Under MTD, contractors need to keep digital records and file through HMRC-approved software. Manual submissions and spreadsheets won't cut it going forward. A.X.E.L is built to be fully MTD-compliant.
Add your subcontractors with their UTR and verification status. As you record payments to them, A.X.E.L automatically calculates the correct deduction rates (20% for verified, 30% for unverified). At month-end, your CIS300 return is ready to submit with full validation and error checking.
Yes. A.X.E.L handles both verified and unverified subcontractors with their correct deduction rates. The system automatically applies 20% deductions for verified subcontractors and 30% for unverified ones. You can easily see each subcontractor's status and update it when they become verified.
A.X.E.L has built-in validation to catch common errors before submission. If you do need to correct a submitted return, you can file an amendment through the platform. All submissions include full audit trails so you can track what was sent and when.
CIS filing is included in all paid A.X.E.L plans starting from £29/month. There are no per-submission fees or extra charges. You get the full platform including leads, quotes, invoices, expenses, and CIS filing all in one price.
Absolutely. You can download submitted returns as PDFs and export all CIS data to CSV for your accountant. A.X.E.L also provides detailed audit trails showing exactly what was submitted and when, giving your accountant full visibility.
A.X.E.L reminds you to file even when you have no payments to subcontractors. You can quickly submit a nil return with just a few clicks. The platform tracks all your submission deadlines so you never miss a filing requirement.
No major changes needed. Just record your subcontractor payments as you normally would in A.X.E.L when managing jobs. The CIS data flows automatically from your job records, so there's no separate CIS system to learn or maintain.
