Construction Industry Scheme deductions + MTD Income Tax is a double-whammy. Pick software that handles both.
If you're a subcontractor under CIS, your contractor deducts 20% (or 30%) at source. Under MTD you still report your gross trading income quarterly. Software with built-in CIS handling (like QuickBooks) saves a lot of manual reconciliation.
