Example 2025/26 HMRC tax report
A small worked example produced by the same engine that powers your real report — Section 104 pooling, split-rate AEA, every rule applied in HMRC's required order.
2025/26 runs at the post-rate-change CGT bands all year: 18% for basic-rate taxpayers and 24% for higher-rate. The £3,000 annual exempt amount is applied automatically. The engine produces the same pooled-cost and disposal table you'd hand to HMRC on the SA108 schedule.
| Asset | Pooled qty | Pooled cost | Avg cost / unit |
|---|---|---|---|
| BTC | 1.5 | £45,000.00 | £30,000.00 |
| ETH | 3 | £6,000.00 | £2,000.00 |
