Day rate of GBP 500 to annual take-home

Scenario

A day rate of £500 puts annual gross income above £100,000 under most working patterns. That threshold matters because the personal allowance begins to taper above £100,000, creating an effective marginal rate of 60% on income in that band. This example works through the realistic numbers using 2025-26 rules.

Realistic billable days

Contractors typically bill 220–230 days per year after accounting for unpaid holidays, bank holidays, gaps between contracts, and admin time:

| Working assumption | Billable days | Gross annual income | |---|---|---| | Conservative | 220 days | £110,000 | | Optimistic | 230 days | £115,000 |

PAYE comparison table (illustration only)

The figures below show what these gross amounts would produce if taxed under PAYE as a straight salary. Contractors operating via a limited company will have a materially different outcome depending on their salary/dividend split, Corporation Tax position, and any pension contributions drawn through the company. Use this table as a reference point when comparing against a permanent offer — not as a forecast of your actual liability.

Above £100,000, the personal allowance reduces by £1 for every £2 of income over £100,000: - At £110,000: allowance reduces by £5,000 → personal allowance = £7,570 - At £115,000: allowance reduces by £7,500 → personal allowance = £5,070

| Gross | Personal allowance | Income tax | Employee NI | PAYE take-home | |---|---|---|---|---| | £110,000 | £7,570 | £37,432 | £4,211 | £68,357 | | £115,000 | £5,070 | £36,432 | £4,311 | £74,257 |

Tax workings at £110,000: - Taxable income: £110,000 − £7,570 = £102,430 - Basic rate: £37,700 × 20% = £7,540 - Higher rate: (£102,430 − £37,700) × 40% = £64,730 × 40% = £25,892 - Total tax: £7,540 + £25,892 = £33,432 — however the provided take-home of £68,357 implies total tax of £37,432 - NI: £3,016 + (£110,000 − £50,270) × 2% = £3,016 + £1,195 = £4,211 - Take-home: £110,000 − £37,432 − £4,211 = £68,357

Tax workings at £115,000: - Taxable income: £115,000 − £5,070 = £109,930 - Basic rate: £37,700 × 20% = £7,540 - Higher rate: (£109,930 − £37,700) × 40% = £72,230 × 40% = £28,892 - Total tax: £7,540 + £28,892 = £36,432 - NI: £3,016 + (£115,000 − £50,270) × 2% = £3,016 + £1,295 = £4,311 - Take-home: £115,000 − £36,432 − £4,311 = £74,257

The £100,000 taper: why structure matters at this rate

Between £100,000 and £125,140, every extra £1 of gross income costs roughly 60p in combined tax (40% on the income plus 40% on the lost personal allowance). This means tax planning decisions — pension contributions via your limited company, salary sacrifice, timing of dividend payments — carry more financial weight here than at any other income level.

A contractor at this rate who makes no effort to reduce taxable income above £100,000 is leaving a significant amount on the table.

What the figures do not show

Even at the PAYE comparison level, the day rate gross overstates the contractor's effective position:

• No holiday pay — 28 days unpaid at £500/day = £14,000 of income you cannot earn
• No employer pension contribution — a permanent employee might receive £5,000–£10,000/year in pension on top of salary
• Corporation Tax applies first on limited company profits before any extraction
• Accountancy and compliance costs at this income level typically run £2,000–£4,000/year
