Shares, funds and crypto in one HMRC-correct Capital Gains Tax engine — same-day, 30-day and Section 104 pooling applied for you, with a rule-by-rule audit trail.
Pooled is tax software for your own investments — not a fund, and not financial advice. It calculates the tax on trades you've already made.

Every disposal is identified under HMRC rules in strict order — same-day, then the 30-day bed-and-breakfast rule, then the Section 104 pool — with the lots and pool state shown for each.
Read off SA108-shaped figures with the annual exempt amount applied, dividend and income context alongside, and a full audit trail to check against.
Import
When an exchange export has no GBP value — a token swap, a staking reward — Pooled flags the row instead of guessing. Fill it in, and the queue clears and your figures unlock. Prices are never silently invented.
Your year
Realised gains with the annual exempt amount applied, ISA allowance used, dividend and income context — each card a shortcut into the detail behind it. Descriptive figures, never a prompt to buy or sell.

Equities, ETFs, funds and crypto flow through the same Section 104 pooling — crypto pooled per token under the same rules HMRC applies to shares.
For every disposal: which rule matched, which acquisition lots were consumed, and the pool before and after. Nothing is a black box.
Swaps are treated as disposals at market value. Missing a GBP value? It is flagged for you to fill — prices are never silently guessed.
See how much of your £20,000 you have used across accounts, with bed-and-ISA disposals handled correctly.
Combine gains with dividends, interest and self-employment figures for an estimated bill and payments-on-account schedule. An estimate, clearly labelled — never advice.
CSVs parse in your browser. Data is workspace-scoped with row-level security, and you can export or delete everything at any time.

For most shares and tokens, HMRC treats all your holdings of the same asset as one pool with a single average cost. When you sell, the allowable cost comes out of that pool pro-rata. Pooled maintains this pool for every asset, across every account, over every tax year.
If you sell an asset and buy the same one back within 30 days, HMRC matches the sale to the repurchase rather than the pool — which defeats a naive sell-and-rebuy loss harvest. Pooled applies this automatically and shows you when it changed your result.
Yes. Both run through the same engine. Each crypto token gets its own Section 104 pool under the identical same-day and 30-day rules, and swaps are treated as disposals at market value.
No. Pooled is an informational tool that computes the tax position of investments you have already made. Every figure is an estimate for information only — verify with HMRC or a qualified accountant before filing.
Pooled implements the same UK share-identification rules for shares and funds, and adds crypto in the same pool set — persisting your pools year to year.
