¿Te preocupa tax treatment when staking Bitcoin or other crypto assets in a pool rather than solo? Many UK taxpayers are uncertain whether rewards or token changes create Income Tax events, Capital Gains Tax (CGT) disposals, or both. This guide gives immediate clarity on the difference between staking pools and solo staking tax consequences, practical timing rules for harvesting losses before the UK tax year end, and step-by-step reporting for Self-Assessment.
Key takeaways: what to know in 1 minute
- Staking rewards are normally taxed as income when received. HMRC treats staking rewards as miscellaneous income in many cases; valuation at receipt matters.
- A disposal for CGT usually occurs when an asset is sold, exchanged or swapped; liquid staking derivatives can trigger disposals. Pools that issue a new token (eg. liquid staking token) may create a disposal on issue or on exchange.
- Solo staking rarely changes ownership; pooled staking often involves token exchanges that create CGT events. The mechanics determine tax outcome.
- Use loss harvesting before the tax year-end to offset gains, but avoid HMRC anti-avoidance traps such as "bed-and-breakfast" rules and artificial wash sale patterns.
- Report harvested losses and staking income on Self-Assessment with clear records: dates, values in GBP, fees and receipts.
Why the distinction between staking pools and solo staking matters for UK tax
The fiscal difference hinges on what actually happens to the taxpayer's property. Solo staking typically retains the same crypto asset on the same private keys; rewards credited are separate receipts. Pooled staking commonly issues new tokens, records partial delegation, or involves exchanges with custodians. Where a token is exchanged for a different identifiable token, HMRC treats that as a disposal for CGT purposes; where rewards are generated and received, Income Tax may apply.
HMRC guidance on cryptoasset taxation sets the underlying tests: HMRC: tax on cryptoassets. The specific mechanics of the staking protocol determine classification: income vs capital event.
How staking rewards and disposals are typically taxed in the UK: short reference
- Income Tax: rewards credited to a wallet (mining, staking rewards) are likely taxable as income at the time of receipt, based on market value in GBP.
- Capital Gains Tax: disposals (sale, exchange, swapping one token for another, gifts other than to spouse) trigger CGT calculations (gain = proceeds minus allowable cost).
- Hybrid events: liquid staking derivatives (eg. stETH-like tokens) can produce a taxable disposal either on issue, on swap back, or on sale depending on substance.

How to determine whether pooled staking created a disposal for CGT
- Identify whether the original asset was exchanged for a different identifiable token or asset.
- Check whether the taxpayer's legal and beneficial ownership changed (custodian model transfers beneficial ownership).
- Review protocol documentation: if the pool issues a receipt token (liquid staking token), treat that issuance/swap as a potential disposal.
- Record timestamps and GBP valuations at each step to support later HMRC enquiries.
Practical example: solo staking vs liquid staking (worked numbers)
- Date A: 1 BTC acquired cost £10,000.
- Solo staking: 0.01 BTC rewarded on 2026-04-01 valued at £700. That £700 is taxed as income at receipt. No CGT disposal until BTC is sold.
- Liquid staking pool: on 2026-04-01 the 1 BTC is swapped for 1 L-BTC (liquid token). If L-BTC is a different token, this swap can be a disposal: proceeds = market value of L-BTC in GBP; gain/loss = proceeds minus £10,000. If disposal occurs, CGT may apply then; subsequent value movements of L-BTC are separate.
When to harvest crypto losses before UK tax year-end
- Harvest losses by disposing assets in the same tax year as gains to offset taxable gains. The UK tax year ends on 5 April.
- For BTC holders with gains in-year, sell or exchange loss-making positions before 5 April to crystallise allowable losses.
- Be mindful of anti-avoidance: the 30-day rule (bed-and-breakfast) treats repurchases made within 30 days as matched to the disposed asset for CGT purposes.
- The superficial loss rule for crypto is not a literal HMRC statutory "wash sale" rule as in some jurisdictions, but HMRC will apply existing CGT matching rules and anti-avoidance (eg. HMRC Capital Gains Manual).
Timing tips to harvest losses safely
- Sell loss positions more than 30 days before repurchasing the same token, or use a materially different token (eg. sell BTC, buy ETH) to avoid the 30-day rule.
- Alternatively, transfer to a spouse (see below) for tax planning within legal bounds.
- Use an aggregated approach: match losses to gains in the same tax year first (same-day, 30-day and then base cost pooling rules apply).
Using loss harvesting to reduce Bitcoin capital gains tax
Loss harvesting lowers taxable CGT by creating allowable losses that offset gains. For Bitcoin:
- Calculate gain per disposal: proceeds (GBP) minus allowable costs (acquisition cost, incidental costs).
- Apply allowable losses first against the same tax year's gains. Any unused losses can be carried forward indefinitely if reported on Self-Assessment.
- Maintain contemporaneous records (date, time, transaction id, GBP value source). HMRC expects robust evidence if audited.
Avoiding HMRC wash sale and bed-and-breakfast traps
UK rules differ from US wash sale rules, but HMRC applies these measures:
- Bed-and-breakfast rule: disposals and repurchases of the same asset within 30 days are matched to the repurchase for CGT purposes, which can negate the intended loss.
- Matching rules: same-day, 30-day and then Section 104 holding (pooled average cost) determine which disposal matches which acquisition.
- Artificial wash patterns: repeated rapid disposals and re-acquisitions designed solely to create losses attract HMRC scrutiny under anti-avoidance provisions.
Practical avoidance steps:
- Wait at least 31 days before repurchasing the same asset in a taxable account.
- If immediate market exposure is required, consider buying a different token (eg. BTC spot vs BTC derivative) but beware substance-over-form and any equivalent economic position tests.
- Use exchange-traded products or differing instruments cautiously; document commercial reasons for any quick repurchase.
Timing disposals to match allowable losses and gains
- Prioritise disposing loss positions in the same tax year as significant gains are crystallised.
- For traders or frequent disposers, use same-day and 30-day matching rules to forecast how a disposal will be matched.
- If near year-end, evaluate whether to crystallise gains shortly before 5 April and offset with harvested losses in the same year rather than carrying either forward.
- Consider the personal allowance and CGT annual exempt amount when timing disposals: if gains fall below the allowance, CGT may be nil.
Transferring assets between spouses to harvest losses
- Transfers between spouses or civil partners living together are no disposal for CGT. Assets pass at base cost, so no immediate gain or loss arises.
- For loss harvesting: transferring a loss-making asset to a spouse and letting them dispose can produce an allowable loss, but this is limited — since transfers are at base cost, the disposal by the spouse will create a loss measured against that base cost only if there is a subsequent market movement.
- Careful use: where one spouse has gains and the other has annual exempt amount unused, transferring assets before disposal can reduce household CGT.
- Document intention and dates. HMRC expects transactions to reflect genuine ownership changes rather than artificial tax-driven constructs.
How to report harvested losses on Self-Assessment
- Calculate allowed loss: disposals minus allowable costs in GBP.
- Use the Self-Assessment capital gains pages to report gains and allowable losses for the tax year.
- Claim unused losses carried forward on the Capital Gains Summary (SA108) and include supporting computations.
- For staking income, include amounts under the relevant Income Tax sections (or include in employment/self-employed pages if applicable).
Required records to support Self-Assessment entries
- Transaction history with timestamps and transaction IDs.
- GBP valuations at receipt/disposal (exchange rate source).
- Fees, commissions, gas costs apportioned where appropriate.
- Protocol documentation showing token mechanics (for pooled vs solo staking).
- Provider statements for centralised pools showing amounts credited and any fees taken.
Visual flow: decision tree for staking pools vs solo staking tax
Step 1 → Is the original token retained on the same legal ownership?
→ If yes: treat rewards as income at receipt; disposal only on sale.
→ If no (exchanged or transferred): treat the transfer as possible CGT disposal and value in GBP at that moment.
Step 2 → Does the pool issue a liquid token?
→ If yes: capture issuance/swap as possible disposal; record GBP values.
→ If no: check provider custody model (beneficial ownership change = disposal risk).
Step 3 → Are there losses to harvest before 5 April?
→ If yes: ensure repurchase timing avoids 30-day matching or use different token/schedule.

Staking tax flow: solo vs pooled
🔒 Solo staking → same token retained ✅ → Income on rewards; CGT on sale later.
🏦 Centralised pool → token transferred to provider ⚠ → possible disposal on transfer; income on payouts.
🔗 Liquid staking → new token issued 🔁 → likely disposal on swap/issue; track GBP valuations.
Advantages, risks and common mistakes
✅ Benefits / when to apply
- Lower record complexity with solo staking where ownership remains.
- Pooled staking can be operationally simpler and produce predictable staking yields.
- Harvesting losses before 5 April reduces CGT for high-gain years when correctly timed.
⚠️ Errors to avoid / risks
- Treating liquid staking tokens as identical to original token without proof; this can lead to unexpected CGT bills.
- Repurchasing within 30 days without understanding bed-and-breakfast rules.
- Failing to account for provider fees, slashing penalties or tax on withheld rewards.
- Not retaining GBP valuations and exchange-rate evidence for each event.
Frequently asked questions
What is the tax difference between staking pools and solo staking?
Solo staking usually keeps the same asset; rewards are taxed as income when received. Pooled staking often involves transfers or new token issuance and can therefore create CGT disposals as well as income events.
Are staking rewards taxed as income or capital gains in the UK?
Staking rewards are typically taxed as income when received (market value in GBP). A later sale of the base asset can create a separate CGT event.
Does receiving a liquid staking token count as a disposal?
Often yes. If an original token is exchanged for a different token, HMRC usually treats the exchange as a disposal for CGT. The exact outcome depends on the protocol's legal and economic substance.
How can losses from Bitcoin be harvested safely before the tax year end?
Sell loss-making positions before 5 April and avoid repurchasing the same asset within 30 days to prevent the 30-day matching rule. Keep full records of dates and GBP valuations.
Can transfers to a spouse reduce household CGT?
Yes. Transfers between spouses are generally no disposal for CGT and can be used to allocate gains to the spouse with lower liability or unused annual exemption. Ensure transfers are genuine and documented.
How should staking income be reported on Self-Assessment?
Include staking rewards as miscellaneous income (or appropriate income box) valued in GBP on the date received, and include CGT disposals on the SA108 capital gains pages.
What records does HMRC expect for staking and loss harvesting?
Transaction logs, GBP price evidence at receipt/disposal, provider statements, fees and gas costs, and protocol docs demonstrating token mechanics.
What happens if HMRC disagrees with the tax treatment?
HMRC can open enquiries; having contemporaneous evidence, rationale and professional advice reduces risk. If disagreement arises, taxpayers have appeal rights through HMRC tribunals.
Your next step:
- Collect a full transaction export from exchanges and wallets with timestamps and GBP conversion sources.
- Classify each staking event: solo reward, transfer to provider, or receipt of liquid token — note which may be income vs disposal.
- If losses are available, plan disposals so they crystallise before 5 April and avoid repurchases within 30 days or justify commercial reasons.
