For most UK owner-managed limited companies, the tax-optimal pay structure is a low salary up to the National Insurance threshold (~£9,100), with the rest extracted as dividends. The exact mix depends on your other income, pension contributions, and whether you''re reinvesting profits.

This guide explains why the low-salary-plus-dividends pattern is so common, the tax mechanics, and where it stops being the right answer.

Why the standard answer is "low salary plus dividends"

Three rates interact:

1. Salary is deducted from company profits before Corporation Tax (reducing the company''s tax bill), but the director pays Income Tax + Employee NIC, and the company pays Employer NIC.
2. Dividends are paid from after-tax profits (company already paid Corporation Tax on them), then the director pays a separate dividend tax rate which is lower than the salary rate.
3. Salary up to the NIC Secondary Threshold (£9,100) is tax-free at both the personal and Employer NIC levels — and still earns you NIC credit toward State Pension.

So the structure that minimises total tax: salary up to the NIC threshold to preserve State Pension entitlement and use the Personal Allowance, then dividends for everything above.

The numbers (2024/25 rates, illustrative)

Assume a single-director company with £60,000 profit available to extract, no other income.

Pure salary:

• Salary: £60,000.
• Personal tax: £12,570 free (PA), £11,430 at 20% basic rate, £36,000 still in basic rate — Income Tax ~£9,486.
• Employee NIC: ~£3,795.
• Employer NIC: ~£7,022 (on £50,900 above secondary threshold).
• Corporation Tax on the £60,000 cost: £0 (it''s an expense, so reduces profit to nil).
• Total tax paid: ~£20,303.
• Director takes home: ~£46,719.

Low salary + dividends:

• Salary: £9,100 (at the secondary threshold). No Income Tax, no NIC.
• Corporation Tax: 19% (small profits rate) on £50,900 = £9,671.
• Dividends available: £50,900 - £9,671 = £41,229.
• Personal tax on dividends: £500 dividend allowance free, ~£3,470 unused personal allowance free, the rest at 8.75% basic-rate dividend tax = ~£3,260.
• Total tax paid: ~£12,931.
• Director takes home: ~£47,069. (£9,100 salary + £41,229 dividend - £3,260 personal tax = £47,069)

The difference: about £350 in the director''s pocket on a £60,000 profit, with significantly less tax friction. At higher profit levels the gap widens because higher-rate Income Tax (40%) bites earlier and harder than higher-rate dividend tax (33.75%).

The numbers move with: rate changes (the dividend allowance dropping from £2,000 to £500 narrowed the gap), the gap between the £9,100 secondary threshold and £12,570 Primary Threshold, and whether Employment Allowance is available (it isn''t for single-director companies with no other employees).

When this pattern doesn''t work

Multiple directors / employees

If you have one or more other employees, you can claim Employment Allowance (£5,000 off employer NIC). In that case, paying salary up to the Personal Allowance (£12,570) is sometimes more efficient than £9,100, because Employment Allowance covers the Employer NIC on the difference.

Reinvesting profits

If you don''t need the cash personally, leave profits in the company. You only trigger personal tax when you extract — keeping money in the company means it''s only taxed at Corporation Tax (19-25%) for now, and you decide when to extract.

Pension contributions

Employer pension contributions are deductible against Corporation Tax (within the £60,000 annual allowance), don''t attract Income Tax or NIC for the director, and grow tax-free in the pension. For higher-earning directors, employer pension contributions often beat both salary and dividends.

Other personal income

If you have other income — rental, dividend from other companies, salary from another role — your personal tax band is partially used up before any dividend from your own company. The optimisation changes.

Mortgage applications

Many UK lenders still treat salary as more dependable than dividend for mortgage underwriting. Some directors temporarily switch to higher salary in the 12-24 months before a mortgage application to look more attractive.

Tax rate changes

The dividend allowance has been cut twice (£2,000 → £1,000 → £500). The dividend tax rates and Corporation Tax small profits rate may change in future Budgets. The strategy is robust to small changes but should be re-modelled annually.

What to do this year

• If you''re a single-director company with no other employees and modest profits, the standard low-salary-plus-dividends pattern is almost certainly optimal.
• If your profits are over £80,000 or you have other income, get a tax projection done. There are sometimes meaningful savings via pension contributions, deferring extraction, or restructuring.
• Document every dividend with a Board resolution and a dividend voucher, declared from distributable reserves. Sloppy dividend paperwork is a common HMRC enquiry trigger.
• Re-run the numbers each year — the optimal mix shifts when rates or thresholds change.
