If you own a limited company agency and have no other income, your salary decision is straightforward once you know the numbers. The most tax-efficient salary for an agency director in 2025/26 is £12,570. That figure is not a guess. It is the exact point where you maximise tax savings without triggering unnecessary costs.

Take a salary above £12,570 and you start paying employee National Insurance at 8% on the excess, plus income tax at 20%. Take a salary below it and you leave your personal allowance unused, pushing more income into higher-taxed dividends. £12,570 is the sweet spot.

This post walks through the full calculation, shows you the savings compared to other approaches, and covers the edge cases where a different salary might make sense. We are ICAEW qualified accountants and we work exclusively with agency founders. These are the numbers we run for every new client.

The Core Calculation: Why £12,570 Works

The logic rests on three tax bands that interact for a director-shareholder.

First, your personal allowance for 2025/26 is £12,570. You pay zero income tax on earnings up to that amount. Second, the primary threshold for employee National Insurance is also £12,570. Earn exactly that figure and you pay no employee NI. Third, your company gets a corporation tax deduction on the salary it pays you, reducing its taxable profit.

Here is how it plays out for a director taking £12,570 salary and the rest as dividends, assuming total drawings of £50,000 from the company.

The Numbers: Salary Plus Dividends

  • Salary: £12,570. No income tax, no employee NI. Company deducts £12,570 from its taxable profit.
  • Employer NI: Zero. The secondary threshold for employer NI is £9,100 per year, but the employment allowance (up to £5,000 for most companies) typically covers it if you have other employees. If you are the only director with no other staff, you pay employer NI at 13.8% on the excess above £9,100. That is £479.02 on a £12,570 salary. Most agency directors claim the employment allowance to wipe this out. If you cannot claim it, your effective salary cost to the company is £13,049.
  • Dividends: £37,430 (to reach £50,000 total drawings). First £500 of dividends are tax-free (dividend allowance). The remaining £36,930 is taxed at 8.75% (basic rate band). Total dividend tax: £3,231.
  • Total personal tax: £3,231. No NI. No income tax.
  • Total tax and NI paid by company and director combined: £3,231 plus £0 (assuming employment allowance claimed).

Compare that to taking the full £50,000 as salary. You would pay income tax of £7,486 (20% on £37,430 after personal allowance), employee NI of £2,994 (8% on £37,430), and employer NI of £5,168 (13.8% on £40,900 after secondary threshold). Total: £15,648 in tax and NI. The salary-plus-dividends approach saves you over £12,400.

That is not a small difference. That is a new hire's salary, a year of software subscriptions, or a significant marketing budget.

What About the £9,100 Salary Option?

Some accountants recommend a salary of £9,100 to avoid employer NI entirely, even without the employment allowance. The logic is that below £9,100, employer NI is zero. But you then leave £3,470 of your personal allowance unused. That £3,470 must come out as dividends instead, taxed at 8.75%. The dividend tax on that extra amount is £304. You save £479 in employer NI but pay £304 more in dividend tax. Net saving: £175. It works, but only if you cannot claim the employment allowance.

If you can claim the employment allowance (and most agencies with at least one employee can), the £12,570 salary is better. You pay zero employer NI and zero employee NI, and you use your full personal allowance.

When a Different Salary Makes Sense

The £12,570 figure assumes you have no other income. That includes no rental income, no savings interest above your personal savings allowance, no freelance work outside your agency, and no state pension. If you do have other income, the calculation changes.

You Have Rental Income or Other Earnings

If your other income already uses up your personal allowance, taking a salary from your agency just triggers tax and NI with no benefit. In that case, the most tax-efficient approach is often to take no salary at all and take everything as dividends. Dividends are not subject to NI and are taxed at lower rates than salary above the personal allowance.

For example, if you have £20,000 in rental profits, your personal allowance is already fully used. A £12,570 salary would be taxed at 20% (£2,514) plus employee NI at 8% (£1,006) plus employer NI at 13.8% (£479). Total cost: £3,999. Taking that £12,570 as dividends instead would cost £1,056 in dividend tax (8.75% on £12,070 after the £500 allowance). You save £2,943.

You Are Approaching the Higher Rate Threshold

If your total income (salary plus dividends plus other income) pushes you into the higher rate band (above £50,270), the dividend tax rate jumps from 8.75% to 33.75%. That changes the arithmetic significantly. In some cases, taking a slightly higher salary to reduce dividend income can save tax overall, because salary reduces the company's profit (saving corporation tax at 19% or 25%) while dividends do not. The trade-off is complex and depends on your exact figures. If your total drawings exceed £60,000-£70,000, ask your accountant to model the salary vs dividend split for your specific situation.

How to Implement the £12,570 Salary

You need to be on the company payroll. That means registering as an employer with HMRC (even if you are the only employee), running payroll each month or each quarter, and submitting RTI (Real Time Information) returns. Most agency directors use software like Xero, QuickBooks, or FreeAgent which include payroll modules. You can also use a separate payroll provider like MoneySoft or BrightPay.

Set your salary to £1,047.50 per month (12 x £1,047.50 = £12,570). Process it through payroll each month. HMRC will collect any tax or NI due through the PAYE system. In your case, assuming no other income and employment allowance claimed, nothing is due.

Your company gets the corporation tax deduction in the period the salary is paid. Make sure the salary is actually paid to you (bank transfer from company to personal account) and recorded correctly in the accounts. A director's loan account entry is not enough, HMRC expects real cash movement.

What About Pension Contributions?

If you want to save more tax, consider making employer pension contributions instead of taking additional salary or dividends. Employer contributions are deductible for corporation tax, are not subject to NI, and do not count as income for the director. They are capped at £60,000 per year (with carry forward from previous years) before the annual allowance charge applies. For an agency director looking to build retirement savings tax-efficiently, this is often a better option than taking more salary.

Common Mistakes We See

Mistake 1: Taking no salary at all. Some directors take everything as dividends to avoid payroll admin. That wastes the personal allowance and means the company gets no corporation tax deduction on the first £12,570 of drawings. The tax cost is roughly £2,200 per year (the corporation tax you could have saved at 19%). Over five years, that is £11,000 lost.

Mistake 2: Taking a salary above the NI threshold without realising. If you set your salary at £13,000, you pay employee NI on £430 at 8% (£34) and income tax on £430 at 20% (£86). Small amounts, but unnecessary. Keep it at £12,570.

Mistake 3: Not claiming the employment allowance. If you have at least one employee (including yourself as a director on a salary), you can claim the employment allowance against your employer NI liability. Many directors forget to tick the box on their RTI submission. The allowance is £5,000 for 2025/26. If you have multiple employees, it covers most or all of your employer NI bill.

Mistake 4: Mixing up the salary with the dividend allowance. The dividend allowance is £500 in 2025/26, not £2,000 as it was in previous years. If you are basing your calculations on old figures, you will overestimate your tax-free dividend income.

What If You Are a Sole Director with No Employees?

If you are the only director and have no other employees, you cannot claim the employment allowance. Your company pays employer NI at 13.8% on the salary above £9,100. On a £12,570 salary, that is £479. In this case, the £9,100 salary (no employer NI) plus dividends up to your required drawings may be slightly better. But the difference is small, about £175 per year as we showed earlier. Many directors prefer the simplicity of £12,570 and accept the £479 employer NI cost.

If your agency grows and you hire staff, you can claim the employment allowance from the point you have at least one employee. Switch to £12,570 at that point.

The Bigger Picture: Your Agency Structure Matters

Your salary is just one piece of your overall tax position. The structure of your agency, your plans for exit, and whether you hold property or IP in separate companies all affect the optimal approach. For most agency directors with no other income and a straightforward limited company, £12,570 salary plus dividends is the right answer. But if your circumstances are more complex, multiple directors, a holding company structure, overseas income, or a planned sale within two years, the calculation changes.
