CIS (Construction Industry Scheme) Compliance: A Must-Have
If you’re working on construction sites, you likely fall under the CIS scheme. This requires you to deduct tax at source from payments to subcontractors. Accounting software with CIS compliance features streamlines this process, automatically calculating deductions, generating CIS returns (monthly and annual), and ensuring you meet HMRC deadlines. Non-compliance can result in penalties, so accurate reporting is crucial. Software like FreeAgent and Xero (with the add-on) are particularly strong in this area.
Tax Filing & Self-Assessment Integration
Most accounting software options facilitate self-assessment tax filing by exporting data in a format HMRC accepts. Some, like QuickBooks Self-Employed, even directly integrate with HMRC, simplifying the submission process. This integration reduces the risk of errors and saves you significant time compared to manual data entry. It’s vital to ensure the software is ‘Making Tax Digital’ (MTD) compliant.
Mobile Accounting: Manage Finances On-the-Go
Mobile apps are essential for contractors. Xero, QuickBooks, and FreeAgent all offer mobile apps allowing you to create and send invoices, record expenses (often with receipt scanning), and check your financial position while on site. FreeAgent’s mobile app is particularly well-regarded for its usability and functionality.
