Real tax planning for a contractor is not a clever trick. It is a short list of legitimate levers, used in the right order, at the rates that actually apply this year. Most of the saving comes from a handful of decisions: how you take money out of the company, whether you use a pension, which expenses you genuinely qualify for, when you declare income, and how you eventually close the company. Get those right and you keep more of what you earn, lawfully, with nothing to fear if HMRC ever asks. Chase the schemes that promise more than that, and you inherit a tax bill years later with interest and penalties on top.

This guide sets out each legitimate lever at 2026/27 rates and explains how they fit together. It is a framework page: where a lever has its own detailed guide, we point you there rather than repeat the mechanics here. The aim is to give you the planning map, then hand you off to the specifics. If you want the levers applied to your own numbers, our contractor accountancy services exist to do exactly that.

Before any lever: your IR35 status sets the ceiling

Tax planning starts with one question that decides how much room you have: is the engagement inside or outside IR35? An engagement caught by the off-payroll rules has its income taxed broadly like employment before it reaches you, which strips out most of the salary-and-dividend planning below. An outside-IR35 engagement run through your own limited company gives you the full set of levers.

So the most valuable planning a contractor does is often nothing to do with the company at all: it is securing and evidencing a genuine outside-IR35 position where the working practices support it, and accepting that an inside engagement is best run simply (frequently through a compliant umbrella) rather than through a personal service company that adds cost without adding planning room. We cover the status tests in depth in what is IR35; the short version for planning purposes is that you cannot plan your way around a genuinely inside engagement, and you should not try to. Everything that follows assumes outside-IR35 work taken through your own company.

Lever 1: get the extraction order right

A limited-company contractor takes money out as some mix of salary and dividends. Salary is a deductible company expense but attracts PAYE and National Insurance. Dividends are paid from post-corporation-tax profit and are taxed on you at dividend rates with no National Insurance. The art is the split, and the maths changed for 2026/27.

What changed in 2026/27

From 6 April 2026 the dividend rates rose under Finance Act 2026 section 4: the ordinary rate is now 10.75% (up from 8.75%), the upper rate 35.75% (up from 33.75%) and the additional rate stays at 39.35%. The £500 dividend allowance is unchanged. Because dividends cost more than they did in 2025/26, the long-standing advantage of paying dividends instead of salary narrowed, and the incorporation advantage as a whole shrank. That does not flip the answer (dividends still carry no National Insurance, so the mix still beats an all-salary draw for most), but it means the split is worth rerunning at the new rates rather than copying last year's numbers.

The salary question has no universal answer

There is no single optimal salary for a contractor director, and any guide that gives you one figure without a caveat is misleading you. The right number turns on three things: whether your company can claim the Employment Allowance, whether you have other income using your personal allowance, and your corporation-tax marginal rate. The first is the big fork.

  • Single director, no other employees. A company whose only employee is a single director cannot claim the Employment Allowance (£10,500 for 2026/27). Employer National Insurance is 15% on salary above the £5,000 secondary threshold. A salary at exactly £5,000 attracts no employer NIC, but it sits below the £6,708 lower earnings limit, so to secure a qualifying National Insurance year (which protects state-pension entitlement) the usual target is the £6,708 LEL, accepting a small slice of employer NIC (15% on the £1,708 between £5,000 and £6,708) as the price of the qualifying year.
  • Company that can claim the Employment Allowance. Where the company has a genuinely employed spouse on the payroll or other staff, salary up to £12,570 is usually optimal: the extra salary above the secondary threshold is relieved by the Employment Allowance (no net employer NIC) and saves corporation tax, which outweighs the employee NIC and income tax cost. Even without the allowance, taking £12,570 rather than £6,708 can give a modest net benefit at 2026/27 rates because the corporation-tax saving on the extra salary exceeds the extra employer NIC, so model it rather than asserting one answer.

Above the salary, dividends fill the rest of the draw, taxed after your other income in their own bands using the £500 allowance and the 10.75% / 35.75% / 39.35% rates. The planning is to use the basic-rate band efficiently and to keep an eye on the £50,270 higher-rate threshold and the £100,000 personal-allowance taper, both of which create sharp jumps in marginal cost. This is the most worked-over decision in contractor tax, and it has its own detailed guide: see the optimal director salary and dividend split for contractors for the modelled numbers, and dividend tax for contractors for the 2026/27 rate detail. The point for this page is simply that the split is lever one, and it now sits below pensions in the order of impact.

Lever 2: the company pension contribution, your biggest lever

If there is one move that does more for a contractor's tax position than any other, it is an employer pension contribution paid by the company. It beats the salary-and-dividend tinkering above because of how favourably it is taxed at every stage:

  • It is deductible against corporation tax on a paid basis (it must be wholly and exclusively for the business), so the company saves tax at 19% to 26.5% depending on its profit level.
  • It carries no employer or employee National Insurance, unlike salary.
  • It is not taxed on you as income when paid in, unlike a dividend, subject to the annual allowance.

The numbers that govern it for 2026/27: the annual allowance is £60,000, measured across all contributions (employer plus personal). It tapers where your threshold income exceeds £200,000 and your adjusted income exceeds £260,000, reducing by £1 for every £2 of adjusted income above £260,000, down to a £10,000 floor. Unused annual allowance carries forward from the previous three tax years (current year used first), which is what lets a contractor make a large one-off contribution in a high-profit year, or before selling or closing the company, without an annual-allowance charge.

The crucial point that contractors miss is the difference between personal and employer contributions. A personal contribution is capped at 100% of your relevant UK earnings, and dividends are not relevant earnings, so a low-salary, high-dividend contractor has almost no personal headroom. An employer contribution from the company is not capped by your earnings at all: it is limited only by the annual allowance, carry-forward and the wholly-and-exclusively test. That is exactly why the employer route is the lever, and why a £6,708 salary does not stop you putting tens of thousands into a pension through the company.

One trap to flag: if you have already flexibly accessed a defined-contribution pension, the money purchase annual allowance of £10,000 may apply instead, and carry-forward is lost for further DC contributions. Check that before planning a large contribution. The full mechanics, including the carry-forward worked example, are in contractor pension employer contributions and contractor pension carry forward. For this guide, the headline is unambiguous: the company pension contribution is the contractor's single biggest legitimate tax lever, and it sits above everything else in the order of impact.

Lever 3: claim the expenses you genuinely qualify for

Day-to-day expenses matter, but they are a smaller lever than the two above, and the saving is real only on costs you actually incur. The test is whether the cost is incurred wholly and exclusively for the business (and, for employees and inside-IR35 work, necessarily). The everyday allowable list for a contractor includes accountancy fees, professional indemnity and public liability insurance, equipment and software, a salary for genuine work, employer pension contributions, allowable business travel and subsistence, use of home, and an apportioned share of phone and internet.

Three rules dominate, and they are where contractors lose claims:

  • The 24-month rule. Travel to a temporary workplace is deductible, but a site stops being temporary once you have spent, or expect to spend, more than 40% of your working time there over a period exceeding 24 months. The clock is about expectation: relief stops from the point you know the engagement will exceed 24 months at one site, not from month 24. This is the single most-misclaimed contractor expense.
  • Inside-IR35 travel. For an engagement caught by the off-payroll rules, home-to-client travel is generally not deductible, because each engagement is treated as a separate employment and the client site becomes a permanent workplace for it. Outside-IR35 contractors keep temporary-workplace relief, subject to the 24-month rule.
  • Mileage (AMAP). For business motoring in your own car or van, the tax-free approved rate is 55p per mile for the first 10,000 business miles and 25p thereafter, from 6 April 2026 (the first-10,000 rate rose from 45p; 25p is unchanged). Ordinary commuting to a permanent workplace does not qualify.

A small but tidy extra: the trivial benefits exemption lets a close company give a director small perks free of tax and NIC, capped at £50 or less per benefit (not cash or a cash voucher, not a reward for services, not contractual), with a £300 annual cap for a director. It is minor, but it is free. The full allowable list, with the documentation HMRC expects, is in the contractor allowable expenses guide. Treat expenses as housekeeping rather than strategy: claim everything you are genuinely entitled to, but do not let chasing small claims distract from the pension lever that dwarfs them.

Lever 4: timing, and the quiet pressure of frozen thresholds

When you take income can matter as much as how. Two timing themes run through 2026/27 planning.

Fiscal drag is working against you

The personal allowance (£12,570) and the higher-rate threshold (£50,270) are frozen to April 2031 (the freeze was extended at the November 2025 Budget). As pay and dividends rise but the thresholds do not, more income is dragged into the 40% and 45% bands every year. For a contractor this is a slow, compounding increase in the cost of taking everything as income annually, and it is the single best argument for the pension lever: money diverted into a pension never crosses those frozen thresholds at all.

Spread declarations across tax years

Dividends are taxed in the year they are declared and made available, not the year the company earns the profit. That gives a contractor genuine, legitimate control: where it suits, you can hold profit in the company and declare dividends across two tax years to keep more of the income within the basic-rate band, to avoid tipping over the £50,270 higher-rate threshold, or to protect the personal allowance once income approaches £100,000 (where it is withdrawn by £1 for every £2 of income, an effective marginal rate that bites hard on dividends taken in that band). The discipline is to forecast the full year's income before declaring the last dividend, not to declare reflexively each month.

The flip side is the temptation to take cash ahead of a declared dividend, which is where the next lever, getting the exit and the loan account right, comes in. Carry-forward of unused pension allowance (lever two) is itself a timing tool: a high-profit year, or the year before you wind the company down, is the moment to sweep up to three years of unused allowance into a single large employer contribution. Timing is not avoidance; it is using the tax year, the bands and the allowances in the sequence the rules already provide.

Lever 5: corporation tax and the associated-company trap

The company side of the bill is corporation tax, and the rate depends on profit: 19% on augmented profits up to £50,000, 25% above £250,000, and the main rate with marginal relief in between (standard fraction 3/200), producing an effective rate of about 26.5% on profits in that £50,000 to £250,000 band. Finance Act 2026 made no change to the corporation tax rates.

The trap contractors fall into is associated companies. The £50,000 and £250,000 limits are divided by the number of associated companies, so a contractor who runs a second company, or whose spouse runs a connected company, can find each company's bands halved, pushing profit into the 26.5% marginal band or the 25% main rate far sooner than expected. Two companies are associated where one controls the other or both are under common control. Before setting up a second company, or assuming a spouse's company sits outside your figures, check whether they are associated, because the answer can materially change the tax on both. The reason this sits in a planning guide is that the corporation-tax rate sets the value of the deductions above: the higher your marginal rate, the more a pension contribution or a genuine expense is worth.

Lever 6: plan the exit before you need it

How you eventually take the accumulated reserves out, or close the company, is a planning decision that should be made early, not in a panic at the end. Three pieces matter.

Keep the director's loan account clean

A personal service company is a close company, so an overdrawn director's loan account (drawings taken ahead of declared salary, dividend or available profit) triggers a section 455 charge: the company pays corporation tax at the dividend upper rate on the loan still outstanding nine months and one day after the period-end. That rate is 35.75% on loans made on or after 6 April 2026 (it was 33.75% on loans made before that date, tracking the dividend upper-rate rise). The charge is temporary, section 458 repays it once the loan is cleared, but the relief is deferred to nine months and one day after the end of the accounting period in which repayment happens, so it is not an instant refund. A loan over £10,000 at any point in the year is also a beneficial-loan benefit in kind unless interest is paid at the official rate. The planning point is simple: keep drawings within your salary plus declared dividends, and clear any overdrawn balance before the deadline rather than financing yourself through the loan account.

Capital versus income on closing the company

When you stop contracting, a solvent Members' Voluntary Liquidation (MVL) can distribute the company's retained reserves as capital rather than as an income dividend. Capital treatment can be worth a great deal if Business Asset Disposal Relief (BADR) applies: BADR reduces the capital gains tax rate on qualifying gains up to a £1m lifetime limit per individual, and the rate is 18% for disposals on or after 6 April 2026 (it was 14% for disposals between 6 April 2025 and 5 April 2026). The conditions, held throughout the two years to disposal, are that the company is your personal company (at least 5% of ordinary shares and voting rights), you are an officer or employee, and the company is trading.

The TAAR is the catch most contractors miss

The reason an MVL is not a free capital exit for a contractor is the targeted anti-avoidance rule (TAAR) in ITTOIA 2005 section 396B. It can re-characterise the capital distribution as an income dividend where its four conditions are all met: (A) you held at least 5% of the company immediately before winding up; (B) the company was a close company at some point in the two years before winding up; (C) within two years of the distribution you continue or get involved in the same or a similar trade or activity; and (D) it is reasonable to assume a main purpose of the winding up was to avoid or reduce income tax. The classic trigger is the phoenix pattern: liquidate, take the reserves as capital, then carry on contracting in the same field. For a contractor who intends to keep working, the two-year same-or-similar-trade limb is the live risk, and it can make BADR irrelevant because the distribution is taxed as income anyway.

The practical sequence is therefore: check the TAAR first, then model the capital and BADR route against simply declaring the reserves as dividends, and only then decide. None of this should be improvised at the end. The full walk-through, including when a strike-off is cleaner than an MVL, is in closing your contractor limited company.

A word on VAT: the Flat Rate Scheme is rarely the win it looks

Contractors often hear that the VAT Flat Rate Scheme saves tax. For most labour-only contractors it does not, because of the limited-cost trader rule: a business spending less than 2% of turnover (or less than £1,000 a year) on goods must use the 16.5% flat rate, which neutralises almost all the scheme's benefit. The test is applied each VAT period. The scheme can still suit a contractor with genuine, regular goods spend above that test, or one who simply values the administrative simplicity, but it should be modelled against standard VAT accounting rather than assumed to be a saving. It belongs on this list mainly to stop contractors treating it as a planning win when it usually is not.

The hard line: where planning ends and avoidance begins

Everything above is legitimate. It uses reliefs, rates and structures exactly as Parliament intended. The schemes that get contractors into trouble are categorically different, and the firm's position on them is an unequivocal do-not-use.

Any arrangement promising take-home pay materially above what a compliant umbrella or a properly run limited company delivers is a tax-avoidance scheme. The usual disguises are loan schemes (you are paid in untaxed loans that are never expected to be repaid), advances, offshore or disguised-remuneration structures, and mini-umbrella fraud. The marketing claims of 80%, 85% or 90%-plus take-home, sometimes dressed up with QC opinions or HMRC scheme-reference numbers that prove nothing. The reality is that the money has not been properly taxed, HMRC treats the arrangement as ineffective, and HMRC pursues the worker, not the promoter, often years later with interest and penalties on top. The loan-charge experience showed how badly this ends for individuals who thought they were following advice.

The compliant comparison is sobering precisely because it is honest: a legitimate umbrella deducts employer National Insurance at 15%, the Apprenticeship Levy and its margin from the assignment rate before paying you a normal PAYE salary, so a higher earner's take-home is realistically in the region of 60% to 70% of the rate. Anything promising far more is promising to do something HMRC will unwind. If you are weighing an umbrella, check for FCSA or Professional Passport accreditation, insist on a clear Key Information Document, and treat any provider that hides how it pays you as a red flag. HMRC's Spotlights and its "Tax avoidance: don't get caught out" campaign list the patterns to avoid.

And mind who runs your company

One related risk sits in your choice of accountant. The Managed Service Company rules carry personal debt transfer (unpaid PAYE can become the worker's, the director's or the provider's debt) and do not depend on any status test, so there is no "outside" finding to win. A genuine independent accountant who advises you, where you make the decisions and could leave freely, is on the safe side of the line. The danger zone is a packaged, standardised "your-company-run-for-you" product where the provider influences or controls how you are paid and how the company is structured. The firm's stance is risk management, not a claim about any named provider: use an accountant who advises, not one who runs the company for you. This matters because the right adviser is the difference between confident, documented planning and a scheme you did not understand.

Putting the levers in order

If you take one thing from this guide, take the order of impact. For a typical outside-IR35 contractor running their own company in 2026/27:

  1. Pensions first. The employer contribution is the biggest legitimate lever, uncapped by your salary, deductible against corporation tax, free of NIC, and unaffected by frozen thresholds.
  2. Then the salary and dividend split, rerun at the new 10.75% / 35.75% dividend rates, with the Employment Allowance fork driving the salary figure.
  3. Then expenses and corporation-tax housekeeping, claiming everything you genuinely incur and watching the associated-company divisor.
  4. Throughout, timing, spreading dividends across tax years and using pension carry-forward in high-profit years.
  5. And finally a planned exit, keeping the loan account clean and checking the section 396B TAAR before assuming an MVL gives you capital treatment.

None of these is exotic, and that is the point. Good contractor tax planning is unglamorous, fully documented, and entirely defensible if HMRC ever asks. It is also genuinely worth a lot of money over a contracting career, which is why it pays to model it against your own figures rather than copy a forum's optimal salary. If you want the levers in this guide applied to your situation, from the pension contribution down to the eventual exit, our contractor accountancy services are built to do precisely that.
