LTIP stands for long-term incentive plan — the umbrella term for share awards that vest over several years if the recipient stays and performance targets are met. Unlike EMI or CSOP, an LTIP is not a statutory tax-advantaged scheme; it is a design pattern, usually built from conditional share awards or nil-cost options, and its defining tax feature is blunt: the value is taxed as employment income at the award's charge point — vest for conditional share awards, exercise for nil-cost options — through payroll where the shares are readily convertible assets, with National Insurance on top. What an LTIP buys is flexibility — any company, any size, any conditions — at full income tax prices.
Because "LTIP" covers several instruments that get confused with each other (and with the tax-advantaged schemes), here is what each actually is and how the tax lands.
The standard LTIP: conditional awards and nil-cost options
A typical LTIP award says: stay three years, hit these targets — EPS growth, TSR ranking, revenue milestones — and you will receive this many shares for nothing (a conditional award) or the right to acquire them for nothing (a nil-cost option). Until vesting there is nothing to tax, because there is nothing owned. At vesting or exercise, the full market value of the shares is employment income: PAYE is operated, employee NIC applies (8% then 2%), and the employer pays 15% NIC on top. Only growth after vesting is capital gain.
The employer's consolations are real: a statutory corporation tax deduction equal to the employees' taxable amount when the shares are acquired, and total design freedom — clawback, malus, holding periods, any performance metric a remuneration committee can imagine. This is why LTIPs dominate listed-company executive pay, where the statutory schemes' limits are irrelevant rounding errors and governance codes demand bespoke conditions.
RSUs: the same tax, an American accent
Restricted stock units — the currency of US-parent employers — are conditional share awards by another name: a promise of shares on a vesting schedule, usually time-based with quarterly or annual tranches. For UK employees the treatment is the LTIP treatment: income tax and NIC on the full value at each vest, through UK payroll, with "sell-to-cover" (the broker selling a slice of the vesting shares to fund the withholding) as standard mechanics. Dividend equivalents paid on unvested RSUs are taxed as earnings too.
Two UK-specific wrinkles catch RSU holders. First, vesting income arrives in lumps that interact badly with the £100,000 personal-allowance taper and payments on account — a £40,000 vest can quietly create a self assessment obligation and a 60% marginal band nobody warned the employee about. Second, employers can pass their 15% NIC onto the employee by election or agreement (the employee gets an income tax deduction for it) — legal, common in US plans, and worth understanding before signing rather than at the first vest. Our private client tax team spends a good share of every January on exactly these returns.
JSOPs and the rest of the zoo
Joint share ownership plans — employee and trustee owning a share jointly, with the employee taking growth above a threshold — pursue capital treatment through co-ownership; they still appear in legacy structures but have largely given way to growth shares, which achieve the same commercial shape more simply. Phantom plans and SARs pay cash by reference to share value: administratively trivial, taxed as bonus, no shareholder dilution and no capital treatment. Each has a place; none changes the underlying rule that value delivered for employment, without a statutory wrapper or genuine market-value acquisition, is income.
Choosing between an LTIP and the alternatives
The ranking for a UK company is consistent. If EMI is available, it wins — capital treatment at 18–24% against income treatment at up to 47% plus NIC is not a close call. CSOP takes the next tier: £60,000 per person, tax-free exercise, no company size limits. Growth shares deliver capital treatment beyond the statutory caps for those willing to carry valuation risk. The LTIP is the right answer where those doors are shut or the design demands things the schemes cannot do: listed-company performance conditions, global plans that must treat forty countries consistently, cash-settled flexibility, or awards to people and amounts the statutory schemes exclude.
What is rarely the right answer is drift: private companies that adopt a US-style RSU plan because the template was to hand, paying income tax rates on value that EMI or growth shares could have delivered as capital. As an illustration of scale: across a management team over a full exit, the rate difference between income and capital treatment on the same value routinely reaches seven figures.
Running one properly
LTIP compliance is payroll compliance: PAYE and NIC operated correctly at every vest (with readily-convertible-asset rules making withholding mandatory for private companies whose shares have a market), the corporation tax deduction claimed, and the annual employment-related securities return filed by 6 July covering every award, vest and acquisition. The recurring failures are operational — vests missed by payroll, internationally mobile employees taxed in the wrong proportions, the ERS return forgotten in a US parent's assumption that someone else files it.
Acumon advises on incentive design across the whole spectrum — choosing the instrument, the valuations, payroll operation and ERS compliance — through our employment tax and tax planning teams. If your plan taxes people at 47% for value a statutory scheme could deliver at 24%, that is not a plan; it is an oversight with a filing deadline.
