Take-home: £32,000 − £10,600 − £1,766 − £530 = £19,104

| Van | Purchase or business proportion of a mixed-use van | Capital allowances (AIA) for purchase; running costs deducted annually |
The Construction Industry Scheme (CIS)
If you take on subcontractors to help with larger decorating contracts, you may need to register as a CIS contractor, deducting tax from subcontractor payments (20% if they're registered with HMRC under CIS, 30% if not) and filing monthly returns. This is separate from — and in addition to — your own Self Assessment tax return as a sole trader, and getting it wrong can lead to penalties, so register promptly if you start regularly engaging subcontractors.

Registering and Filing
Register for Self Assessment once gross income exceeds £1,000 in a tax year. Keep a simple system of job-by-job income records and expense receipts throughout the year, and file your Self Assessment return online by 31 January following the end of the tax year, paying any Income Tax and Class 4 NI owed by the same date.
