The outside IR35 money flow: start to finish
When a contractor wins an outside IR35 engagement, the day rate is paid to the limited company gross of VAT (if applicable). From that point, the company's money passes through several stages before it reaches the contractor's personal account. Understanding each stage is what separates a contractor who makes the most of the structure from one who is surprised by the actual amount that lands.
The flow runs like this: day-rate income arrives in the company, the company deducts allowable business expenses, pays corporation tax on the resulting profit, and the director then draws the post-tax profit as a combination of salary and dividends. Each step carries a tax implication. This page works through all of them using 2026/27 figures.
The comparison with inside IR35 is a separate calculation, covered fully in the inside IR35 take-home guide. This page focuses on the outside-IR35 route.
Step 1: income into the company
The starting point is the day rate agreed with the client or agency. For illustration, take a contractor billing £500 per day. At 226 working days per year (after holidays), the company turns over approximately £113,000. VAT, if the company is registered, is separate: the company charges 20 percent VAT on top of the fee, collects it from the client, and remits it to HMRC quarterly. VAT is a cash-flow item, not an income item, and does not feature in the take-home calculation.
The company's income for corporation tax purposes is the fee income, not the VAT-inclusive amount collected. Most labour-only contractor companies are standard-rated and not on the flat rate scheme, so input VAT on costs can be reclaimed in the usual way.
Step 2: deductible expenses reduce taxable profit
Before corporation tax applies, the company deducts all allowable business expenses. These are costs incurred wholly and exclusively for the business. For a typical outside-IR35 contractor the most significant items are:
- Director's salary. Salary is a deductible payroll cost. The company deducts the gross salary plus any employer NIC before reaching taxable profit.
- Employer pension contributions. Contributions paid directly from the company into the director's pension are deductible against corporation tax, carry no employer or employee NIC, and are not taxed on the director as income when paid in. This is the single most tax-efficient extraction route and is covered further below.
- Accountancy and professional fees. Contractor accountant fees, contract review costs and professional indemnity insurance are deductible.
- Equipment and software. Computers, subscriptions and specialist software are deductible, either immediately (via the annual investment allowance) or via capital allowances.
- Business travel. Travel to temporary workplaces is deductible. Outside IR35 the contractor can claim travel to the client site as long as the site qualifies as a temporary workplace. The 24-month rule applies: if an engagement is expected to last more than 24 months at the same site, or involves more than 40 percent of working time there, the travel becomes non-deductible from the point that expectation is formed. Mileage in a personal vehicle is reimbursed at the approved AMAP rate of 55 pence per mile for the first 10,000 business miles from 6 April 2026 (25 pence thereafter), and this reimbursement is a deductible company cost.
- Use of home. A portion of home running costs can be claimed where a home office is genuinely used for business.
- Phone and broadband. Business-proportion costs are deductible.
For a contractor with modest deductible expenses (say £8,000 per year including salary, NIC and overheads but excluding pension), the taxable profit on £113,000 of fee income might be around £105,000 before pension contributions. Adding a £20,000 employer pension contribution reduces taxable profit to £85,000.
Step 3: corporation tax on profit
Corporation tax is charged on the company's taxable profit for the accounting period. The 2026/27 rates are:
| Profit level | Rate |
|---|---|
| Up to £50,000 (small profits rate) | 19% |
| £50,001 to £250,000 (marginal relief) | 19% to 25% (effective marginal rate approx. 26.5%) |
| Above £250,000 (main rate) | 25% |
Finance Act 2026 made no change to corporation tax rates: the rates above are identical for financial years 2025 and 2026. The £50,000 and £250,000 thresholds are divided by the number of associated companies where a contractor has more than one company under common control, or a connected spouse company, so the bands shrink in those cases.
Using the £85,000 taxable profit example (after the £20,000 employer pension contribution), corporation tax falls partly in the small profits band and partly in the marginal relief band. Approximately:
- First £50,000 at 19 percent: £9,500
- Next £35,000 in the marginal band at an effective marginal rate of 26.5 percent: approximately £9,275
- Total CT: approximately £18,775
Post-tax company profit available for distribution: £85,000 minus £18,775 equals approximately £66,225.
Step 4: extracting profit via salary and dividends
Post-corporation-tax profit sits in the company. To reach the contractor's personal account it must be extracted as salary or dividends. The salary is already accounted for (it was deducted before CT), so the remaining question is how much of the retained profit to draw as dividends and when.
The salary decision
A single-director company that cannot claim the Employment Allowance typically sets salary at approximately £6,708 for 2026/27. This is the lower earnings limit (LEL), the threshold at which a tax year counts as a qualifying year for state pension and national insurance credits. At exactly £5,000 (the secondary threshold) no employer NIC is due, but salary below the LEL does not generate a qualifying year. Most contractors accept the small employer NIC cost (15 percent on the £1,708 between £5,000 and £6,708, equalling approximately £256 per year) in exchange for the qualifying year.
The salary is also a corporation tax deduction, so the gross salary plus employer NIC comes out of pre-CT profit. At £6,708 salary plus £256 employer NIC, the CT saving at 19 percent is around £1,325, which partially offsets the NIC cost.
Where the Employment Allowance is available (for example because a genuine employee spouse is on the payroll), a salary up to £12,570 is usually more efficient: the allowance offsets the employer NIC, and the extra salary saves CT without triggering much personal income tax. The detailed salary modelling for different situations is in the director salary and dividend split guide.
Dividend taxation in 2026/27
Dividends are paid from post-corporation-tax profit and taxed on the director personally at dividend tax rates. For 2026/27, following the changes in Finance Act 2026 section 4, the rates are:
| Dividend falls in | Rate (2026/27) |
|---|---|
| Within the £500 dividend allowance | 0% |
| Basic-rate band (up to £50,270 total income) | 10.75% |
| Higher-rate band (£50,271 to £125,140) | 35.75% |
| Additional-rate band (above £125,140) | 39.35% |
These rates rose from 8.75 percent and 33.75 percent that applied in 2025/26 and earlier years. The ordinary and upper rates each increased by 2 percentage points from 6 April 2026; the additional rate of 39.35 percent is unchanged. Dividends are taxed after salary and other income, so they sit on top of the basic-rate band already partly used by the salary.
The personal allowance for 2026/27 remains £12,570 (frozen to April 2031). Income within the personal allowance carries no income tax, including dividends. Dividends are taxed in their own order, after non-savings and savings income, using the £500 allowance first.
Worked example: £500/day, outside IR35, 2026/27
The following example uses round numbers and a realistic but simplified expense profile. Individual results vary.
Assumptions:
- Day rate: £500, 226 working days, fee income: £113,000
- Director salary: £6,708 (LEL)
- Employer NIC on salary: £256 (15% on £1,708 above secondary threshold)
- Employer pension contribution: £15,000 (into a SIPP or occupational scheme)
- Other business expenses (accountancy, insurance, software, travel): £5,000
- No Employment Allowance (single director)
Company profit calculation:
- Fee income: £113,000
- Less salary (£6,708) + employer NIC (£256) + pension (£15,000) + other expenses (£5,000): £26,964
- Taxable profit: £86,036
Corporation tax:
- £50,000 at 19%: £9,500
- £36,036 in marginal relief band at approx. 26.5% effective marginal rate: £9,549
- Total CT: approximately £19,049
Post-CT distributable profit: £86,036 minus £19,049 equals approximately £66,987.
Personal income received:
- Salary: £6,708 (within personal allowance, no income tax; employee NIC below primary threshold at this level, so effectively zero Class 1 employee NIC)
- Dividends drawn: £60,000 (leaving £6,987 retained in company)
Personal tax on £60,000 dividends:
- Remaining personal allowance after salary: £12,570 minus £6,708 equals £5,862
- £5,862 of dividends within personal allowance: £0 tax
- £500 dividend allowance: £0 tax (this allowance still uses up £500 of basic-rate band space)
- Basic-rate band space for dividends: the basic-rate band runs to £50,270 of total income and is £37,700 wide (£50,270 minus the £12,570 personal allowance). The salary sits entirely within the personal allowance, so the whole £37,700 band is available to dividends. The £500 dividend allowance occupies £500 of that band at 0 percent, leaving £37,200 of dividends taxed at the basic dividend rate.
- Basic-rate dividend tax (£37,200 at 10.75%): approximately £3,999
- Remaining dividends above the basic-rate threshold (£60,000 minus the £5,862 covered by the personal allowance, minus the £500 allowance, minus the £37,200 taxed at the basic rate, equals £16,438) fall into the higher-rate band: £16,438 at 35.75%: approximately £5,877
- Total personal dividend tax: approximately £9,876
Summary take-home:
- Net salary received: £6,708 (employee NIC negligible at this level)
- Dividends drawn: £60,000
- Personal tax paid on dividends: approximately £9,876
- Net personal take-home: approximately £56,832
- Plus pension: £15,000 (in the pension fund, not personal income now but part of personal wealth)
- Effective overall take-home (including pension): approximately £71,832
As a percentage of £113,000 fee income, the net personal take-home (cash) is approximately 50 percent, rising to approximately 64 percent when the £15,000 pension contribution is included. The retained profit of £6,987 in the company has already had CT paid on it and is available for future dividends or further pension contributions without additional CT.
A contractor choosing not to make the £15,000 pension contribution would pay more CT (on the higher profit) and potentially more dividend tax (drawing the retained profit as dividends). The pension contribution is typically the most efficient lever for reducing the combined CT and dividend tax bill.
How the incorporation advantage works: the NIC comparison
The core reason outside-IR35 contractors using a PSC retain more than employees or inside-IR35 workers is the NIC treatment of dividends. An employee pays 8 percent employee Class 1 NIC on earnings from £12,570 to £50,270, and the employer pays 15 percent above £5,000. Dividends carry no NIC at all.
For a basic-rate contractor drawing £50,000 in total income (salary plus dividends), the combined NIC saving versus the same income all taken as salary is significant. At a £6,708 salary, employee NIC is negligible (the salary sits between the secondary threshold and the LEL/primary threshold band where NIC arises). Employee NIC only starts at the primary threshold of £12,570, so a £6,708 salary generates no employee NIC. The employer pays 15 percent on the £1,708 above £5,000, approximately £256.
Compare this with an equivalent employee salary of £60,000: employee NIC would be 8 percent on £37,700 (£50,270 minus £12,570) plus 2 percent on £9,730 (£60,000 minus £50,270), totalling approximately £3,211 employee NIC, plus employer NIC of 15 percent on £55,000 equals £8,250. The combined saving is about £11,461 per year on a £60,000 income, even before the corporation tax advantage on the lower salary.
That NIC advantage is absent when a contractor is caught inside IR35: the fee-payer operates PAYE and NIC on the deemed payment before paying the PSC, removing the dividend option entirely on that income.
The pension contribution: the biggest lever
Employer pension contributions from the company sit outside the NIC system entirely. The company deducts them before computing CT, so they save corporation tax at 19 to 26.5 percent depending on the marginal rate. They are not income in the director's hands when paid, so no income tax or dividend tax arises until pension benefits are drawn (usually in retirement, often at a lower rate).
The annual allowance for 2026/27 is £60,000 (covering both employer and personal contributions). A contractor who has not made full contributions in the previous three tax years can use carry-forward to contribute more than £60,000 in a single year, subject to the rules. This is valuable for a contractor in a high-profit year who wants to extract profit efficiently without triggering higher-rate dividend tax.
The company pension contribution is not limited by the director's salary (unlike a personal contribution, which is capped at 100 percent of relevant earnings), so a low-salary high-dividend contractor can make a large employer contribution directly. This is explored in employer pension contributions for contractors.
What proportion of a day rate is typically kept?
The answer depends heavily on the contractor's choices, but some broad ranges for 2026/27 are:
| Scenario | Approximate take-home as % of day-rate income |
|---|---|
| £500/day, basic structure, no pension, low expenses, all profit drawn as dividends (dividends cross into the higher-rate band) | about 61% cash |
| £500/day, structured extraction (LEL salary, £15,000 employer pension, expenses), remaining profit drawn as dividends | about 50% cash, rising to about 64% counting the pension as personal wealth |
| Lower day rate where total personal income stays inside the basic-rate band (so all dividends are taxed at 10.75%) | about 70 to 72% cash |
These are illustrative figures, not guaranteed outcomes. The pattern is the important part: at a £500/day rate the cash that reaches the contractor's account is around half the gross once corporation tax and higher-rate dividend tax are paid, and an employer pension contribution is what lifts effective retention toward two-thirds. Retention nearer three-quarters only holds at lower day rates where total income stays inside the basic-rate band and the 35.75 percent higher dividend rate is avoided. The actual figure depends on the level of legitimate expenses, the Employment Allowance position, how much profit is taken as dividends versus retained or contributed to pension, and the timing of distributions across tax years.
The 2026/27 dividend rate rises have reduced these percentages slightly compared with 2025/26. For a basic-rate contractor drawing £40,000 in dividends, the extra 2 percentage-point increase in the ordinary dividend rate costs approximately £800 per year. This is meaningful but does not overturn the fundamental tax efficiency of the PSC structure for most contractors.
Higher day rates: when dividends cross into the higher-rate band
A contractor billing £600 per day (approximately £135,600 per year at 226 days) will, after salary, expenses and even a reasonable pension contribution, have enough distributable profit that drawing all of it as dividends in a single year pushes significant amounts into the 35.75 percent band. At that point the structure still outperforms employment (no employer NIC on the dividend portion, CT already paid at 25 percent rather than income tax at 40 percent on the same income as salary), but the margin narrows.
Three common responses at this level:
- Increase the employer pension contribution. A higher pension contribution reduces the taxable profit, lowers the CT bill and reduces the amount available to draw as dividends, keeping more of the dividend income in the basic-rate band. A contractor with carry-forward allowance from previous years can make a large one-off contribution.
- Retain profit in the company. Profit left in the company has CT paid on it but attracts no personal tax until drawn. A contractor expecting a lower-income year (for example after a gap between contracts, or on a part-year basis) can defer the dividend draw to that year, when more of it falls in the basic-rate band at 10.75 percent rather than 35.75 percent.
- Review the salary level. Where the Employment Allowance is available (usually because a genuine second employee is on the payroll), a higher salary up to £12,570 saves more CT than it costs in personal tax and NIC at lower income levels. At very high profit levels the calculus shifts again, but for most contractors in the marginal CT band taking a salary at or near the personal allowance is worth modelling.
The personal allowance taper is also a risk at higher income levels. Where adjusted net income exceeds £100,000, the £12,570 personal allowance is withdrawn at £1 for every £2 of income above that level, creating a 60 percent effective marginal income tax rate between £100,000 and £125,140. Contractors drawing dividends in that range should consider pension contributions specifically to bring adjusted net income below £100,000 and preserve the full personal allowance.
What this page does not cover
The arithmetic above illustrates the tax flow. The question of how to structure the salary/dividend split optimally across different income levels, Employment Allowance eligibility and profit-retention strategies is a full topic in itself. That detail belongs in the director salary and dividend split guide, which covers the precise salary thresholds, the EA fork and the retained-profits planning strategies.
This page also assumes outside-IR35 status has been properly established and documented. Outside-IR35 status is not guaranteed by a contract clause or a CEST result alone: it depends on the actual working practices matching the contractual terms, and the whole picture test governs. The practical steps to protect and evidence outside status are covered in the wave-1 guide protecting outside IR35 status.
For the inside-IR35 equivalent, where the fee-payer operates PAYE and NIC and the salary/dividend split is no longer available on that income, see the inside IR35 take-home guide.
A note on the 2026/27 dividend rate changes
Finance Act 2026 (which received Royal Assent on 18 March 2026) raised the dividend ordinary rate from 8.75 percent to 10.75 percent and the upper rate from 33.75 percent to 35.75 percent, with effect from 6 April 2026. The additional rate of 39.35 percent was not changed. The dividend allowance remains £500 (unchanged since April 2024). These changes apply to dividends received in the 2026/27 tax year and beyond.
Any outside-IR35 take-home estimate using the pre-April-2026 rates (8.75 percent / 33.75 percent) will overstate what contractors actually keep from 2026/27 onwards. The difference is real but proportionate: the structure remains more efficient than employment, but marginally less so than in prior years.
Getting the structure right matters more than the arithmetic
The percentages above only materialise if the contractor's limited company is properly run. Late dividend declarations, insufficient distributable reserves, directors' loans that trigger a section 455 charge, or an accountant whose model crosses into the managed service company rules can all erode the effective take-home. Working with a specialist contractor accountant who understands the PSC structure, the IR35 interaction and the annual salary/dividend/pension planning cycle is what makes the arithmetic real rather than theoretical.
