Business Tax Planning for UK Limited Companies

You've reviewed the accounts, the company has made a healthy profit, and the familiar salary-plus-dividend arrangement is still in place. It worked when profits were lower. Now corporation tax bands, dividend tax, National Insurance, pension allowances and personal income all interact, so the same arrangement may no longer be the most efficient route.

Effective business tax planning starts with profit extraction, not with a list of isolated expenses. The practical order is to identify the company's corporation tax position, decide how much profit should be paid or retained, compare salary, dividends and pension contributions, then review expenses, capital allowances and wider structures. Compliance remains the guardrail, but strategy determines how much value reaches you and how much remains available for the company's future.

Why Most UK Directors Leave Money on the Table

A common meeting starts with a director looking at last year's accounts and asking why the company paid more tax than expected. The salary was set years ago, dividends were declared when cash was available, and pension contributions were made only when there happened to be money left. Nothing was necessarily wrong, but the decisions weren't made as one connected plan.

Most owners default to a comfortable pattern because it feels familiar. They repeat the previous year's salary, draw dividends at regular intervals and treat pension contributions or timing decisions as secondary matters. That approach becomes less reliable when profit levels change, personal income moves between tax bands, or the company sits near corporation tax thresholds.

Practical rule: Treat remuneration, profit timing and structure as three connected levers, not three separate tax topics.

The first lever is remuneration. Salary creates a deductible company cost and may support National Insurance records or personal borrowing applications, while dividends use post-corporation-tax profits and depend on sufficient distributable reserves. Employer pension contributions can reduce company profit without becoming immediate salary or dividend income.

The second is profit timing. A deductible cost paid before the accounting period ends may reduce taxable profit in that period. A planned purchase deferred into the next period may leave this year's profit higher, which can affect the corporation tax band and the best extraction mix.

The third is structure. Share ownership, associated companies and holding arrangements can change how profits are taxed, but added entities also bring filings, administration and professional fees.

A sensible decision sequence is:

  1. Fix the profit forecast and identify the corporation tax band.
  2. Choose the extraction mix, considering salary, dividends and pensions together.
  3. Capture allowable costs and capital allowances before the period ends.
  4. Review structural options only when the expected benefit exceeds their ongoing cost.
  5. Check documentation and distributable reserves before implementing anything.

Generic “salary plus dividends” advice often underperforms once profits exceed £50,000, because the company may enter the Marginal Relief band and the director's personal tax position may change. Tax planning works best when the director decides what the profit is for first, then selects the most suitable route to extract, reinvest or shelter it.

How Corporation Tax Bands Shape Your Planning

The company's taxable profit is the starting point for every extraction decision. For financial years beginning from 1 April 2023, the small profits rate is 19% for profits below £50,000, the main rate is 25% for profits above £250,000, and Marginal Relief applies between those limits, as set out in HMRC's corporation tax Marginal Relief guidance.

The middle band matters because it doesn't operate like a simple step from one rate to another. Marginal Relief creates a tapered effective outcome, commonly described as about 26.5% for companies within much of that range. The precise calculation depends on taxable profits, the accounting period and associated companies, so a company near either limit should model the result rather than rely on a headline rate.

Profit Band Tax Rate Notes
Below £50,000 19% Small profits rate for eligible companies
£50,000 to £250,000 Marginal Relief applies Tapered effective rate between the lower and upper limits
Above £250,000 25% Main rate

The £50,000 and £250,000 limits aren't always available in full. They're reduced where a company has associated companies, and they're adjusted for short accounting periods. This catches groups that have grown gradually, particularly where a trading company sits alongside an investment, property or holding company. A group's structure can therefore affect the rate applied to each company's profit.

Consider two companies, each with £120,000 of profit, compared with one company earning £240,000. Two separate companies don't automatically receive two untouched sets of thresholds if they're associated. Their limits are shared, which can leave both companies exposed to Marginal Relief. The combined tax outcome may therefore be worse than the result for one company with the same overall profit, although commercial, legal and risk considerations must come first.

For a company near £50,000, an employer pension contribution or a properly timed deductible cost may reduce taxable profit into the 19% band. For a company approaching £250,000, bringing forward genuine business expenditure can prevent additional profit from falling into the main rate, but spending money solely to obtain tax relief rarely makes economic sense.

A company with profits in the middle band needs more careful modelling than one comfortably below or above it. Use a Marginal Relief calculation guide to understand the mechanics, then test the figures against associated companies and the company's accounting period.

Salary, Dividends and Pensions as Profit Levers

Salary, dividends and employer pension contributions solve different problems. The right answer depends on company profit, the director's personal income, cash requirements and willingness to defer access to funds.

A salary of £12,570 can use the personal allowance without creating income tax for the director, but it can create employer National Insurance of roughly £590 and employee National Insurance of roughly £600 under the assumptions in the relevant director remuneration guidance. It also gives the company a deductible employment cost and can help preserve a qualifying National Insurance record for the State Pension. The actual result depends on the wider payroll and the director's other income.

Dividends are paid from profit after corporation tax. The £500 dividend allowance means the first £500 of dividend income is taxed at 0%, while dividend rates are 8.75% at the basic rate, 33.75% at the higher rate and 39.35% at the additional rate, before considering corporation tax already paid by the company. The rate changes applying from 6 April 2026 increase the basic-rate dividend tax rate to 10.75% and the higher-rate rate to 35.75%, while the dividend allowance remains £500, according to the 2026 director salary and dividend analysis.

Employer pension contributions have a different tax profile. Where the normal business expense rules are met, the company can deduct a contribution from taxable profit. The contribution generally isn't treated as immediate employment income or subject to employee or employer National Insurance, making it particularly useful where the company is trying to manage its corporation tax position. The HMRC pensions guidance on employer contributions explains the treatment.

Lever Corporation Tax Relief Income Tax/NI Cost to Director Key Trade-off
Salary Usually deductible Income tax and National Insurance may apply Creates visible income and pension-record benefits, but payroll taxes can arise
Dividends No further deduction Dividend tax applies after corporation tax Flexible, but requires distributable reserves
Employer pension Usually deductible when properly incurred Generally no immediate income tax or NI Efficient, but funds are restricted until pension access

A director taking £12,570 salary, £40,000 dividends and a £30,000 employer pension contribution may retain more value than a director taking £50,000 salary and £37,000 dividends, depending on the company's starting profit and the director's wider income. The pension contribution reduces company profit and avoids turning the same amount into higher-rate personal income. It also changes the timing of access, which is a real cost rather than a technical footnote.

That trade-off matters. Pension funds are locked away until the applicable minimum pension age, stated in the planning assumptions as age 55, while salary can help with mortgage applications and dividends can fund immediate spending. The best mix isn't the one with the lowest tax in isolation. It's the one that matches the director's cash needs, personal tax band and longer-term objectives. This guide to pension contribution tax relief is useful when comparing the options.

A Worked Example for a Director on £120,000 Profit

Take a single-director company with £120,000 of profit before the final extraction decisions. The figures below are planning illustrations, not a tax calculation for every director, because personal income, payroll details, accounting dates and pension history can alter the result.

The first approach is a salary-led structure. A £12,570 salary uses the personal allowance and is deductible for corporation tax. On the stated assumptions, the company cost is about £15,233, including employer National Insurance, while the director avoids income tax on the salary and retains a clear employment income figure.

A second approach uses a £9,100 salary, described in the planning notes as the National Insurance threshold, with the balance extracted as dividends. Compared with the larger salary, this creates a £5,000 difference in salary, but the company also loses the corresponding corporation tax deduction and the director receives more dividend income. The personal result depends on whether the dividends fall within the basic, higher or additional dividend bands, and the post-2026 dividend rates make that comparison more important.

The third approach adds a £40,000 employer pension contribution. That contribution reduces taxable company profit and, under the stated illustration, can move the company's taxable profit into the 19% band. The corporation tax reduction is roughly £6,000, while the director receives no immediate taxable income on the contribution. The money is being redirected into retirement savings, not made available for current spending.

Approach Salary Employer Pension Dividends Corporation Tax Director Take-Home
Salary-led £12,570 None Lower dividend requirement Higher than pension-led approach Visible salary, with less immediate dividend flexibility
Salary plus dividends £9,100 None Higher dividend requirement Based on higher taxable profit More accessible income, with dividend tax exposure
Salary, dividends and pension £12,570 or planned salary £40,000 Lower dividend requirement Reduced by pension deduction Lower immediate cash, stronger retirement funding

The important point isn't that the pension-led structure always wins. A director who needs a mortgage, has little pension provision or needs cash for a property deposit may prefer more visible or accessible income. A director with higher-rate personal income and sufficient cash reserves may place greater value on the corporation tax deduction and the absence of immediate dividend tax.

The example also shows why profit extraction should follow the corporation tax analysis. Paying a dividend first and considering a pension contribution later can leave the company in a less favourable band, while making an oversized pension contribution without checking annual allowance history can create a different problem.

Expenses, Capital Allowances and Profit Timing

Profit extraction starts after the company has identified its genuine business costs. Directors should capture expenses that support the trade, including directors' subsistence, a reasonable home-office apportionment, business phone and broadband use, and professional subscriptions. The company needs a clear business purpose, appropriate records and receipts. A personal purchase doesn't become deductible because it appears on a company card.

Capital allowances deal with qualifying assets rather than ordinary running costs. The £1 million annual investment allowance can provide a significant deduction for qualifying plant and machinery, while structures and buildings allowance is available at 3% under the planning assumptions. Cars have separate treatment, with the writing-down allowance rate affected by their CO2 emissions. The detailed classification can become difficult when an asset has mixed business and private use.

A business guide illustrating methods to reduce corporate tax through deductible expenses, capital allowances, and profit timing.

The timing decision is often more valuable than directors expect. A cost incurred before the accounting period ends may reduce taxable profit in that period, potentially helping a company move towards the 19% band. Deferring a planned purchase into the next accounting period can leave current profit higher, which may produce a less favourable corporation tax outcome.

Before the year-end, check:

  • Receipts and records: Capture allowable costs and document their business purpose.
  • Asset purchases: Confirm whether equipment is qualifying plant or machinery before ordering.
  • Period-end dates: Check when costs are incurred, paid and placed in service.
  • Capital allowance pools: Review existing pools, private use and disposal adjustments.
  • Cash impact: Don't spend £1 solely to save a fraction of that amount in tax.

The annual investment allowance guidance is a useful reference, but pooling and mixed-use assets can require professional review. An accountant should check the position where the company has several asset classes, associated entities, property improvements or significant disposals.

When Holding Companies and Family Structures Make Sense

Structural planning should come after the basic extraction decisions. A holding company may allow surplus cash or investments to sit outside the trading company, separating some assets from day-to-day trading risk and delaying personal extraction. It adds another company, however, with further accounts, tax returns, records and professional fees.

The benefit is strongest when profits are consistently high and there's substantial cash to retain. The planning threshold in this context is profits above £250,000, where the main corporation tax rate applies. If the shareholder immediately needs the money personally, a holding company may only defer the personal tax point rather than remove it. The structure must also have a commercial reason and be implemented carefully.

A spouse shareholder can support dividend splitting where the lower-earning spouse has unused personal allowance or dividend allowance. The shares must be genuine, the rights must be understood and the arrangement must not be a paper exercise designed solely to redirect income. The £5,000 dividend allowance and HMRC settlements rules make careless arrangements vulnerable to challenge.

EIS and VCT investments are more specialised. They may suit a profitable director with capital to invest and an appetite for the risks associated with early-stage or unlisted businesses, but they aren't a general-purpose shield for company profits. Investment risk, liquidity and eligibility conditions matter as much as tax relief.

Add a structure only when the expected tax, asset protection or investment benefit exceeds the accountancy, filing and administration cost.

That test is more useful than copying a structure seen in another company. A holding company that works for an owner retaining surplus cash may be unnecessary for a contractor withdrawing most profits each year. A spouse shareholding can be appropriate where ownership reflects genuine arrangements, but it shouldn't be created without reviewing share rights and settlements rules.

Compliance Traps and HMRC Risk to Watch For

The largest risk usually isn't a missed minor expense. It's applying a technically attractive idea without checking the conditions that make it valid.

Associated companies can reduce the corporation tax thresholds available to each company, pushing profits into Marginal Relief or the 25% main rate sooner than expected. Groups should review control, ownership and commercial relationships before assuming each company receives a separate full set of limits.

Pension planning has two separate constraints. The planning notes refer to a £30,000 cap on income tax relief in a particular context, alongside the £60,000 annual allowance for 2025/26, which covers employer, personal and third-party contributions across pension arrangements. The annual allowance is measured by tax year rather than company accounting period, so directors need to check carry-forward, tapered allowance and historic contributions before making a large payment. HMRC's employer PAYE and National Insurance guide provides the relevant allowance information.

Benefits in kind create another common gap. Company assets used privately, director loans and informal arrangements need correct documentation and reporting. A loan without proper records can create tax charges, while a benefit that seems minor can become expensive when repeated.

Dividends also require more than a bank transfer. The company needs sufficient distributable reserves, appropriate board minutes and dividend paperwork. Declaring dividends that the accounts don't support can create personal tax and company-law problems.

Personal service companies must also consider IR35 when contracting with medium and large clients. The contract, working practices and client determination all matter. A label such as “outside IR35” doesn't settle the question.

Errors involving disputed tax arrangements can lead to Accelerated Payment Notices, while loans to participators can trigger Section 455 charges. The HMRC compliance checks guidance helps explain the wider enquiry process. A chartered tax adviser may cost less than defending an avoidable enquiry, particularly where the company has multiple entities, pension funding or complex extraction.

Building Your Own Tax Planning Priorities

Start with a reliable company profit forecast. Don't begin by asking whether salary or dividends are better. First identify taxable profit, the relevant accounting period, associated companies and whether the company sits below £50,000, within Marginal Relief or above £250,000.

Next, set a salary based on the director's circumstances and National Insurance position. The stated 2026/27 planning figures put the employer secondary threshold at about £5,000 a year, or about £96 a week, while the employee primary threshold remains £12,570. Employee National Insurance is stated as 8% between £12,571 and £50,270, and 2% above that, so salary should be modelled rather than selected by habit. Review the National Insurance threshold guidance for directors alongside the company's payroll facts.

Then layer in dividends, checking the director's wider income and the company's distributable reserves. Before taking further dividends, test whether an employer pension contribution better serves the director's objectives and company tax position. The £60,000 annual allowance for 2025/26 should be checked against all contributions, not just the amount paid by the company.

After remuneration, review expenses, capital allowances and one-off timing decisions. Capture genuine costs before the accounting period closes, but don't buy assets to create a deduction. Only then assess a holding company, spouse shareholding or investment structure. The planning framework here treats structures as worth considering once profits are consistently above £150,000, but the decision still depends on cash retention, ownership, risk and administrative cost.

A quarterly review is usually enough to catch changes before they become expensive. Update the profit forecast, check personal income, confirm pension capacity, review planned purchases and record any changes in share ownership or associated companies. That habit turns business tax planning from a year-end scramble into an organised decision process.
