Salary gap closer

name: salary-gap-closer
description: When a candidate's ask is above the client's offer, works out what the gap is worth to the candidate after tax and what it costs the client, then which mix of salary, signing bonus, pension, holiday, WFH days and a pay review closes it, in year one and year two, with the working shown. UK tax built in at the 2026/27 rates; elsewhere it uses the rates the recruiter gives. Use when the recruiter says 'the candidate wants 60k and the client offers 55k', 'close the gap', 'salary negotiation', 'what package would get this over the line' or 'can a signing bonus fix it'. BOUNDARY - this closes the gap on one offer; to compare two or more whole offers side by side, use offer-comparison, and for a candidate weighing a counter-offer from their current employer, use counter-offer-conversation.

# Salary gap closer

You help an agency recruiter close the gap between what a candidate is asking for and what the client is offering. £5,000 on paper is a different number to each side: the candidate loses tax, National Insurance and their own pension contribution, and the client adds employer NI and its pension. You show both numbers, then which mix of salary, signing bonus, pension, holiday, WFH days and a pay review closes the gap for the least, in year one and year two.

**A guide, not financial advice.** It applies the rates as written to the figures entered. The candidate's own tax position can change the answer; if money turns on it, check with an accountant. UK rates as of 21 October 2026 (tax year 2026/27), from Hikari's free salary negotiation calculator. Checked every April.

## What you need

1. **The candidate's ask** and **the client's offer**, a year.
2. **Country.** For the UK: England, Wales and Northern Ireland, or Scotland (Scotland has its own income tax bands).
3. **The client's package:** client pension %, candidate pension %, holiday days (with bank holidays), office days a week, commute cost a day (return) and commute time a day (minutes, return).
4. **The package on the table**, if there is one: extra salary, signing bonus, extra client pension points, extra holiday days, extra WFH days a week, and any pay review (% rise, after how many months).
5. **Outside the UK only:** the tax and employee charges the candidate pays on extra pay (%), and the client's on-costs on top of salary (%), such as social charges.

**Draft first.** If you have enough to make a useful first version, write it now, in this reply: mark anything missing as "To confirm", state any assumption you made in one line, and put your questions at the end. Only stop to ask before writing when something essential is missing entirely. The ask, the offer and the country are essential. Outside the UK, the two rates are essential too, except where noted below.

## Rates: where they come from

- **UK:** use only the 2026/27 rates and method in `references/gap-method.md`, exactly as written there. Don't adjust them, round them differently or add rules of your own.
- **Outside the UK:** there are no built-in rates. Ask the recruiter for the two rates above and work every sum from them, in the country's currency. **Never supply a tax rate, social charge or on-cost for another country from your own knowledge**, even if asked. Suggest the client's payroll or the country's tax authority instead.
- **UAE, Qatar and Saudi Arabia** don't tax salaries (as the source page states, citing the UAE, Qatari and Saudi government sites), so tax starts at 0% there. On-costs such as social insurance or end-of-service gratuity depend on the client: ask for theirs.
- Outside the UK, client pension is assumed to carry no tax or charges, as in the UK. Say so, and say it should be checked locally. Treat the result as an estimate, except in the three Gulf countries where tax really is 0%.

## How to work

1. **Check there is a gap.** If the offer is at or above the ask, say so and stop.
2. **Work out the gap four ways** (method in `references/gap-method.md`): on paper, take-home, worth to the candidate (take-home plus everything paid into their pension), and cost to the client of paying the full ask.
3. **Price each option, one unit at a time,** on top of the client's offer: £1,000 more salary, a £1,000 signing bonus, one more point of client pension, one more day of holiday, one more WFH day a week. For each: worth to the candidate, cost to the client, and what the candidate gets for each £1 the client spends. Name the cash option that goes furthest.
4. **Work out the package on the table**, if one is given, in one go (so tax bands are crossed correctly): worth, cost, % of the gap closed, still short, and how much less (or more) it costs the client than paying the full ask. Do it for **year one** and **year two**. A signing bonus is paid once, so it counts in year one only. A pay review counts for the months after it in year one and the full twelve months in year two.
5. **If no package is given,** suggest one or two mixes built from the cheapest options that close the gap in both years, and show the same year-one and year-two figures for each.
6. **Show your working** step by step, and round to the nearest pound in the tables.

## Rules

- Holiday and WFH days are time, not cash. Show them at the values in the method, and label them "time". A day of holiday costs the client no extra cash but is a day not worked: say so.
- A WFH day a week can only be offered if they are in the office at least that many days now.
- A pay review is only worth something if it's written into the offer. Say so whenever one is used.
- A signing bonus that closes the gap in year one leaves the candidate short from year two. Say how short.
- Don't say whether the ask is fair or what the market pays. If asked, say you don't hold verified salary data and suggest recent placements or a salary survey.

# Gap method and UK rates (2026/27)

Source: Hikari's free salary negotiation calculator (hikari-ai.co.uk/tools/salary-negotiation-gap-calculator), which takes the UK figures from GOV.UK, "Rates and thresholds for employers 2026 to 2027" (checked 21 October 2026). Use these figures exactly. Don't add others.

## UK rates

**Income tax** is charged on income after the candidate's own pension contribution (a net pay pension).

- Personal allowance: £12,570. Above £100,000 of income, it falls by £1 for every £2 over £100,000.
- Taxable income = income less the personal allowance. The bands below are on TAXABLE income.
- **England, Wales and Northern Ireland:** 20% on the first £37,700; 40% from £37,700 to £125,140; 45% above £125,140.
- **Scotland:** 19% on the first £3,967; 20% to £16,956; 21% to £31,092; 42% to £62,430; 45% to £125,140; 48% above.

**Employee National Insurance** is on gross pay (salary plus any bonus), before the pension contribution: 8% between £12,570 and £50,270, and 2% above £50,270.

**Employer National Insurance:** 15%. The tool assumes pay is above the employer NI threshold, so every extra £1 of salary or bonus costs the client £1.15 plus pension.

**Assumptions to state:** net pay pension, standard tax code, pay above the NI thresholds, no student loan.

## The sums

Write the client offer as OFFER, the ask as ASK, the client pension as ER%, the candidate pension as EE%, and holiday days as HOL.

**Package at a salary S, with a one-off bonus B and client pension ER% (UK):**
- Candidate pension = S × EE%. Client pension = S × ER%. (No pension on a bonus.)
- Income tax on (S + B − candidate pension).
- Employee NI on (S + B).
- Take-home = S + B − candidate pension − income tax − NI.
- **Worth to the candidate = take-home + candidate pension + client pension.**

**Outside the UK** (T = tax on extra pay, entered; ON = on-costs, entered):
- Take-home = (S × (1 − EE%) + B) × (1 − T). Candidate pension = S × EE%. Client pension = S × ER%.
- Worth = the same three added together.
- Use ON in place of the 15% employer NI everywhere below.

**The gap**
- On paper = ASK − OFFER.
- Take-home gap = take-home at ASK − take-home at OFFER.
- Worth gap = worth at ASK − worth at OFFER. This is "the gap the candidate feels".
- Cost to the client = (ASK − OFFER) × (1 + 15% + ER%).

**One unit of each option, on top of OFFER**
- Working days a year, WD = 260 − HOL.
- **£1,000 salary:** worth = worth at (OFFER + 1,000) − worth at OFFER. Cost = 1,000 × (1 + 15% + ER%).
- **£1,000 signing bonus, once:** worth = take-home at OFFER with B = 1,000 − take-home at OFFER. Cost = 1,000 × 1.15. No pension on it.
- **One more point of client pension:** worth = cost = OFFER ÷ 100. Client pension carries no NI, so it reaches the candidate whole.
- **One more day of holiday:** worth = take-home at OFFER ÷ WD (their take-home day rate). Costs no extra cash; it is a day not worked. Label it time.
- **One more WFH day a week:** worth = (WD ÷ 5) × commute cost a day. Hours saved = (WD ÷ 5) × commute minutes ÷ 60. Costs no cash. Label it time. Only possible if they're in the office at least one day a week now.
- **Per £1** = worth ÷ cost, for the cash options only.

**The package on the table** (extra salary X, bonus B, extra pension points P, extra holiday days H, extra WFH days a week W, review R% after M months)
- New salary S2 = OFFER + X. New client pension ER2 = ER% + P. Salary after review S3 = S2 × (1 + R%).
- Share of year one after the review = (12 − M) ÷ 12. M must be 0 to 12.
- Review, year one: worth = (worth at S3 − worth at S2, both with ER2 and no bonus) × share; cost = (S3 − S2) × (1 + 15% + ER2) × share.
- Time = H × day rate + W × (WD ÷ 5) × commute cost a day.
- **Year one worth** = (worth at S2 with bonus B and ER2 − worth at OFFER) + review worth + time.
- **Year one cost** = X × (1 + 15% + ER%) + S2 × P ÷ 100 + B × 1.15 + review cost.
- **Year two worth** = (worth at S3 with ER2, no bonus − worth at OFFER) + time.
- **Year two cost** = (S3 − OFFER) × (1 + 15% + ER%) + S3 × P ÷ 100.
- **% closed** = worth ÷ worth gap. **Still short** = worth gap − worth (or "Closed"). **Less than paying the full ask, by** = cost to the client of the full ask − package cost (negative means the package costs more).

## Worked example (England, from the calculator)

Ask £60,000, offer £55,000, client pension 5%, candidate pension 5%, 33 days' holiday, 3 office days, £15 a day and 90 minutes commute.

- At £55,000: candidate pension £2,750; tax on £52,250 = £8,332; NI £3,110.60; take-home £40,807.40; worth £46,307.40.
- At £60,000: candidate pension £3,000; tax on £57,000 = £10,232; NI £3,210.60; take-home £43,557.40; worth £49,557.40.
- Gap: on paper £5,000; take-home £2,750; worth £3,250; cost to the client £5,000 × 1.20 = £6,000.
- Options: £1,000 salary worth £650, costs £1,200 (£0.54 per £1). £1,000 signing bonus worth £580, costs £1,150 (£0.50). One pension point worth £550, costs £550 (£1.00). One holiday day worth £179.77 (227 working days). One WFH day a week worth £681 and 68.1 hours.
- Package of £2,000 salary, £2,000 signing bonus and one pension point: year one worth £3,030, cost £5,270, 93% closed, £220 short, £730 less than the full ask. Year two worth £1,870, cost £2,970, 58% closed, £1,380 short.
