Recommended selection process

  1. 1. Score each tool against the weighted criteria above with your accounts and operations teams.
  2. 2. Test CIS verification with your actual subcontractor base, not demo data.
  3. 3. Verify deduction calculations handle labour/materials splits correctly for your typical payment scenarios.
  4. 4. Run a test monthly return cycle from start to HMRC submission.
  5. 5. Check whether subcontractor onboarding captures CIS data alongside other compliance documents.
  6. 6. Confirm CIS statement generation and distribution works for your subcontractor volume.

Frequently asked questions

What is CIS management software?

CIS (Construction Industry Scheme) management software helps contractors comply with HMRC CIS requirements. This includes verifying subcontractor tax status, calculating correct deduction rates, generating monthly CIS returns, filing with HMRC, and producing CIS statements for subcontractors. Good CIS software automates these processes to reduce errors and missed deadlines.

Do all construction businesses need CIS software?

Any contractor paying subcontractors for construction work in the UK must comply with CIS requirements. While small contractors with few subcontractors can manage CIS manually through HMRC's online portal, software becomes essential as subcontractor volumes grow. The risk of calculation errors, missed returns, and penalties increases significantly with manual processes.

What CIS deduction rates apply?

There are three CIS deduction rates: 0% (gross payment status, subcontractor is registered and meets HMRC criteria), 20% (standard rate for registered subcontractors), and 30% (higher rate for unregistered subcontractors). Software should automatically apply the correct rate based on the most recent HMRC verification and alert you when status changes affect deductions.

Can accounting software handle CIS?

Some accounting packages include CIS modules that handle basic deduction calculations and HMRC filing. However, these are typically designed for generic accounting workflows rather than construction-specific needs. They often lack subcontractor onboarding, document management, compliance tracking, and integration with payment application workflows that construction contractors need.

How often do CIS returns need to be filed?

CIS monthly returns must be filed with HMRC by the 19th of each month following the tax month end (5th). Late returns incur automatic penalties: a GBP 100 fine for each month of the first 6 months late, with higher penalties beyond that. CIS software should automate return preparation and provide deadline reminders to prevent late filing.

What happens if CIS deductions are calculated incorrectly?

Incorrect CIS deductions can result in HMRC penalties and interest charges for the contractor. Over-deductions cause cashflow problems for subcontractors and damage working relationships. Under-deductions create tax liabilities for the contractor. Automated software reduces these risks by applying verified rates and handling labour/materials splits correctly.
