> **Primary Statutory Authority:** HMRC BIM52751, ITTOIA 2005 §§ 803–828 & The Income Tax (Digital Requirements) Regulations
> **Executive Direct Answer:** Income Tax (Trading and Other Income) Act 2005 § 803 establishes Qualifying Care Relief (QCR) allowing foster carers with income below their threshold to record zero taxable profits; HMRC has confirmed QCR-only carers are exempt from quarterly MTD for ITSA mandates.
> **Pre-Computed Statutory Output (£38,000):** **£0.00 Taxable Profit (100% Tax-Free)** — 2026/27 QCR Limit: £47,220 (headroom £9,220) · 2025/26 QCR Limit: £45,430.
## ⚡ Side-by-Side Statutory Comparison Matrix
| Comparison Parameter | Self Assessment (SA100/HS236) | MTD for ITSA (Post-April 2026) | Statutory & Financial Impact |
| :--- | :--- | :--- | :--- |
| **Filing Frequency** | **Single annual return by 31 January following tax year** | **Quarterly digital updates + final year-end declaration** | MTD quadruples reporting touchpoints for non-exempt sole traders |
| **QCR Carer Exemption Status** | **Standard simplified reporting via Box 4 of Self Assessment return** | **Statutory exemption confirmed for pure qualifying care income** | Foster carers solely receiving qualifying care payments avoid mandatory MTD commercial software costs |
| **Dual-Income Threshold Impact** | **Combined self-employment + foster turnover declared on return** | **Mandatory MTD enrollment if outside qualifying turnover exceeds £50,000** | Secondary sole-trader income (e.g. childminding, consulting) can trigger MTD digital requirements |
| **Digital Record-Keeping Tooling** | **Spreadsheets or standard paper bookkeeping fully accepted** | **API-enabled MTD compatible software required for qualifying entities** | Eliminates £250–£600 annual recurring software subscriptions for qualifying carers |
> **Statutory Trade-Off & Nuance:** If a foster carer operates a separate self-employed business with gross receipts over £50,000 (lowering to £30,000 in April 2027), they must enroll in MTD ITSA for that trade while maintaining separate QCR accounting for care allowances.

## Frequently Asked Questions
### Do foster carers have to submit quarterly accounts under Making Tax Digital from April 2026?
No. Foster carers whose total income falls within Qualifying Care Relief or whose qualifying fostering income is not treated as commercial trading income are exempt from quarterly MTD ITSA reporting.
### Can foster carers claim capital allowances for home alterations?
Under the simplified Qualifying Care Relief method, carers cannot claim separate capital allowances or individual expense receipts, as the weekly statutory allowance covers all operational costs.
