Virtual Assistant Tax UK 2026/27: Home Office, Software and a £18,000 Example
Self-employed virtual assistants work entirely from home with software subscriptions as the main cost. Full worked example on £18,000 turnover and the simplified home-use-as-office deduction.
A lean, software-driven cost structure
Virtual assistants work entirely from home, serving multiple clients through video calls, email and cloud-based tools — which means the cost base is almost entirely software subscriptions and a proportion of home running costs, with none of the physical kit or premises costs that define many other self-employed trades.

Open Take-Home Pay calculatorSimplified flat rate vs actual costs
HMRC's simplified home-use-as-office flat rate scales with monthly hours worked from home, and it's designed to avoid the need to calculate an exact business-use percentage of your household bills. For most VAs working a moderate number of hours a week, this flat rate is simpler and produces a reasonable deduction — but if your household running costs are unusually high, or you work very long hours from a dedicated home office, calculating the actual business-use percentage of rent/mortgage interest, utilities and council tax can sometimes produce a larger claim. It's worth running both numbers in your first year to see which suits your circumstances.

uk-trading-allowance-self-employed-guide-2026Frequently asked questions
Can a virtual assistant claim the simplified home-use-as-office flat rate?
Yes. HMRC's simplified expenses flat rate for working from home is based on hours worked from home each month (a fixed amount per month once you pass 25 hours, rising at higher hourly thresholds), and covers a proportion of household running costs without needing to calculate an exact business-use percentage of the home.
What software subscriptions can a VA deduct?
Project management tools, calendar/scheduling software, email marketing platforms, accounting/invoicing software, cloud storage and any specific tools used for client work (social media schedulers, transcription tools) are all fully deductible ongoing business costs.
Do virtual assistants need to register as self-employed even with several small clients?
Yes, once total self-employment income across all clients exceeds £1,000 in a tax year, regardless of how many separate clients that income comes from — HMRC looks at total trading income, not client count.
How much tax does a virtual assistant pay on £18,000 turnover?
After typical expenses of around £1,800-£2,200 (software subscriptions, home-use-as-office flat rate, marketing, accountancy), taxable profit lands around £15,800-£16,200, giving combined income tax and Class 4 NI of roughly £840-£920.
Should a VA use the actual-cost method or the simplified flat rate for home working?
The simplified flat rate is usually easier and sufficient for a VA working modest hours from a shared home space, since it avoids detailed bill-splitting calculations. Those working very long hours from a dedicated home office, or with unusually high household running costs, may find the actual-cost method (calculating an exact business-use percentage of bills) produces a bigger deduction — it's worth comparing both in your first year.
