Childminder Tax and Allowable Expenses 2026/27: A Self-Employed Guide
Registered childminders are almost always self-employed, filing Self Assessment and claiming a distinctive set of allowable expenses — including HMRC's specific household cost percentages for childminders. Here's how it works in 2026/27.
Self-Employment Status
Registered childminders overwhelmingly operate as self-employed sole traders — they set their own hours, fees, and terms with the parents who use their service, take on the financial risk of running their own small business, and aren't employed by any single family or agency in the traditional sense. This means the standard self-employed tax framework applies: registering for Self Assessment, paying Income Tax on profits (after allowable expenses), and paying Class 4 National Insurance (and, since Class 2 was largely abolished, benefiting from automatic National Insurance credits at profit levels above the small profits threshold).
What Counts as Allowable Expenses
Childminders can deduct legitimate business expenses from their income before calculating taxable profit, similar to any self-employed trader, but with some distinctly childminding-specific categories:
| Expense category | Examples |
|---|---|
| Food and drink | Meals and snacks provided to minded children |
| Toys, books and equipment | Items used specifically for childminding activities |
| Outings and activities | Entry fees, travel costs for trips with minded children |
| Cleaning and consumables | Cleaning products, nappies/wipes if provided, first aid supplies |
| Insurance | Public liability insurance, other relevant business insurance |
| Registration and compliance | Ofsted (or equivalent) registration fees, DBS check costs |
| Training | Paediatric first aid courses, safeguarding training, other required CPD |
| Advertising and admin | Website, printed materials, accountancy fees, phone/internet business proportion |
| Household running costs | A proportion of heating, electricity, water, council tax, mortgage interest/rent |
The Household Expense Calculation
Because childminding happens in the childminder's own home, HMRC recognises that a portion of ordinary household running costs are genuinely business expenses — but calculating this precisely (room by room, hour by hour) would be impractical for most childminders. HMRC has published simplified percentage guidance specifically for childminders, reflecting typical patterns of business use, rather than requiring the same detailed calculation approach used by other home-based self-employed workers under the general simplified expenses flat-rate scheme.
Always check the current HMRC guidance specifically for childminders (search "HMRC childminder expenses" or refer to HMRC's business income manual) for the exact percentages in force, since childminder rates are set out separately and may be updated periodically.
What You Can't Claim
- Costs that are entirely personal and unrelated to childminding (your own family's food, for example, as distinct from food provided to minded children)
- Capital costs for major home improvements not specifically related to childminding use (though certain capital allowances may apply to some equipment — check with an accountant)
- Fines or penalties
Registering and Filing
- Register with HMRC for Self Assessment as self-employed, typically by 5 October following the end of the tax year in which you started childminding.
- Keep clear records throughout the year — receipts for expenses, a simple log of hours/days worked, and mileage records for any outings using your own vehicle.
- File your Self Assessment return by the 31 January online deadline (or 31 October for paper returns), declaring your total childminding income and deducting allowable expenses to arrive at taxable profit.
- Pay Income Tax and Class 4 National Insurance on the resulting profit, and budget for Payments on Account if your tax bill exceeds the relevant threshold, since these can catch newer self-employed people out in their second year of filing.
VAT Considerations
Most individual childminders operate well under the VAT registration threshold (£90,000 in 2026/27), so VAT registration typically isn't relevant. However, childcare services carry their own specific VAT exemption rules under UK VAT law, which can apply regardless of turnover in some circumstances — larger childminding operations, nurseries, or those running multiple staff/assistants should check their specific VAT position, ideally with an accountant familiar with the childcare sector.
Practical Tips
- Use dedicated software or a simple spreadsheet to log daily/weekly hours worked with each family, which supports both your expense apportionment and your income declaration.
- Keep receipts digitally (photograph and store) as well as physically, since HMRC can request evidence for any claimed expense during an enquiry.
- Consider an accountant experienced with childminders specifically — the household expense percentages and sector-specific considerations are niche enough that general self-employment guidance doesn't always cover them well.
- Review your expense claims annually against current HMRC guidance, since simplified rates and thresholds are periodically updated.
