Crypto Staking Income and the £100k Personal Allowance Taper: The 60% Trap (Plus Child Benefit and Childcare)

A £90,000 salary and £12,000 of staking rewards does not mean £12,000 taxed at 40%. Between £100,000 and £125,140 of income the personal allowance is withdrawn at £1 for every £2, which turns a 40% marginal rate into an effective 60%. Crypto rewards are income for this purpose. Capital gains are not. Getting that distinction right is worth thousands of pounds to anyone near the threshold.

Why rewards count and gains do not

HMRC treats staking rewards, airdrops received for doing something, and mining receipts as miscellaneous income at their sterling value on receipt (CRYPTO21200, CRYPTO21250, CRYPTO21150), unless the activity amounts to a trade in which case they are trading income. Either way they are income for the Income Tax Act 2007.

The personal allowance taper in ITA 2007 s.35 is based on "adjusted net income" — total income, less gross pension contributions and Gift Aid donations. Miscellaneous income is in. Capital gains are charged under a different Act entirely (TCGA 1992) and are not income, so they never enter adjusted net income. Selling £200,000 of Bitcoin does not touch your personal allowance. Receiving £12,000 of staking rewards can.

The same adjusted net income figure drives two other thresholds:

• High Income Child Benefit Charge (ITEPA 2003 s.681B onwards): from 6 April 2024 the charge starts at £60,000 and claws back all Child Benefit by £80,000, at 1% of the benefit for every £200 of income over £60,000.
• Tax-Free Childcare and 30 hours' free childcare: eligibility ends if either parent's adjusted net income exceeds £100,000. This is a cliff edge, not a taper.

The numbers: 2025/26, rest of UK

Personal allowance £12,570. Taper: reduced by £1 for every £2 of adjusted net income above £100,000, reaching zero at £125,140.

Worked example. Salary £96,000. Staking rewards during the year £6,000, valued on each day of receipt. No pension contributions beyond the workplace minimum, which has already been deducted from the £96,000.

Without the rewards, income is £96,000, personal allowance intact, higher-rate tax on the top slice at 40%.

With the rewards, adjusted net income is £102,000. That is £2,000 over the threshold, so the personal allowance falls by £1,000 to £11,570. The effect:

• Tax on the £6,000 of rewards at 40%: £2,400
• £1,000 of previously tax-free allowance now taxed at 40%: £400
• Total extra tax caused by the £6,000: £2,800, an effective rate of 46.7%

Push it further. Salary £96,000 and rewards £16,000: adjusted net income £112,000, allowance reduced by £6,000 to £6,570. The rewards cost £6,400 at 40% plus £2,400 from the lost allowance: £8,800, or 55%. Every pound of reward between £100,000 and £125,140 is taxed at 60% once you look only at that band.

In Scotland the arithmetic is worse because the higher rate is 42% and the advanced rate 45%: the effective rate in the taper band is 67.5%. See the Scottish crypto tax guide.

Child Benefit example

Two children, Child Benefit of roughly £2,250 a year (2025/26 rates). One parent earns £58,000 and receives £8,000 of airdrops and staking.

Adjusted net income £66,000. That is £6,000 over the £60,000 threshold, so 30% of the Child Benefit — about £675 — is clawed back through the High Income Child Benefit Charge on the Self Assessment return. The other parent's income is irrelevant unless it is higher. The £8,000 of crypto income has cost £3,200 at 40% plus £675 of charge: 48%.

Childcare cliff edge

A parent on £97,000 with two children under five receiving 30 hours' free childcare and Tax-Free Childcare top-ups is typically getting benefits worth £6,000–£10,000 a year depending on nursery fees. £4,000 of staking rewards takes adjusted net income to £101,000 and removes the entitlement for the whole year. There is no taper. A £4,000 reward can cost more than £4,000.

What you can do about it

Pension contributions. A personal pension contribution reduces adjusted net income by the gross amount. In the first example, a £2,000 gross contribution (£1,600 net of basic-rate relief) brings income back to £100,000, restores the full allowance and gets 40% relief on the contribution. The crypto SIPP guide covers pensions and crypto more broadly — crypto itself cannot go into a pension, but the cash from selling it can.

Gift Aid. Same mechanism; the gross donation reduces adjusted net income.

Timing you do not control. Rewards are taxable when you receive them, or when they are credited and available to you. Delaying a claim on a protocol that only makes rewards yours when claimed can move income between tax years, but HMRC will look at when you had the right to the tokens, not just when you pressed the button. Do not rely on this without advice.

Put staking in the lower earner's name. If a spouse or civil partner is under the thresholds, assets transferred to them are no-gain/no-loss under TCGA 1992 s.58 and future rewards are theirs. See spousal transfers.

Stop staking, or stake less. If the rewards are 5% on £100,000 of holdings and the effective tax rate is 60% plus a childcare cliff, the after-tax return can be negative. It is a legitimate answer.

Keep gains as gains. Selling appreciated tokens is CGT at 18%/24% with a £3,000 exemption and no effect on adjusted net income. For someone in the taper band, a capital gain is taxed at less than half the rate of the same pound of reward income.

Student loan repayments: the £2,000 unearned income rule

A less-known threshold catches younger stakers. If you file a Self Assessment return and your unearned income — which includes miscellaneous income such as staking rewards, along with interest and dividends — exceeds £2,000 in the year, the whole amount is added to your earnings for student loan repayment purposes. Below £2,000 it is ignored. A graduate on Plan 2 earning £35,000 with £2,500 of staking rewards therefore repays 9% of the full £2,500 (£225) on top of their normal repayments, whereas £1,900 of rewards would trigger nothing. Capital gains are not income and never count. The student crypto guide covers the position for those still studying.

Summary of thresholds

The last row is the one place where both matter: rewards use up the basic rate band, which then pushes more of your gains into 24% rather than 18%. See basic vs higher rate CGT.

Where it goes on the return

Rewards are reported on SA100 box 17 (other taxable income) with a note that they are cryptoasset income; the personal allowance taper and the Child Benefit charge are computed by HMRC from the totals. Gains go on SA108 and stay out of the income calculation. A calculator that shows income and gains separately, as cryptolens.uk does on its tax page, makes it obvious which figure is pushing you over which threshold.
