If you run payroll for someone who is also a director of another company, you need to handle their PAYE carefully. HMRC treats each employment separately for National Insurance, but combines them for tax code purposes. Get it wrong and you could under-deduct tax, overpay NI, or trigger penalties.

This guide covers the practical steps for PAYE for director with two companies: how tax codes work, what happens to National Insurance, and which HMRC forms you need to file. We'll use real numbers throughout so you can apply this to your own situation.

When Does This Situation Arise?

It is common. A director of a growing limited company might also sit on the board of another business. A contractor working through their own Ltd might take a second director role in a joint venture. Or a husband-and-wife team running a Birmingham café might each be directors of both the trading company and a separate property holding company.

In each case, both companies must operate payroll for the director. But HMRC's systems treat the two employments differently depending on whether the director has a single tax code or two separate codes.

How HMRC Allocates Your Tax Code

Every employee gets a tax code. For most people with one job, that code is applied to that single employment. But when someone has two employments, HMRC must decide how to split their personal allowance.

The standard approach is that HMRC allocates the full personal allowance to the main employment and issues a BR (basic rate) or D0 (higher rate) code to the second employment. This means the first employer deducts tax using the full tax-free amount, and the second employer taxes all earnings at 20% (BR) or 40% (D0).

For a director with two companies, the allocation depends on which company pays the most. If the director earns £40,000 from Company A and £20,000 from Company B, HMRC typically gives Company A the full personal allowance (code 1257L) and Company B a BR code. Company A deducts tax on £27,430 (£40,000 minus £12,570). Company B deducts tax on the full £20,000 at 20%.

The combined tax should be correct, provided both companies operate the codes HMRC has issued.

What If HMRC Issues Two Codes With Personal Allowance?

Sometimes HMRC splits the personal allowance. You might see code 800L on one employment and code 457L on the other. This happens when HMRC decides to share the allowance between the two jobs.

If you receive a code that includes part of the personal allowance, use it as issued. Do not override it. HMRC's calculation will be correct for the combined earnings, but only if both employers use their allocated code.

The risk with split codes is that if one employer stops paying the director, the other code might be too low. The director would need to contact HMRC to have the allowance reallocated.

National Insurance: The Key Difference

National Insurance works differently from income tax. Each employment is treated separately. The director pays NICs on each job based on its own earnings, not on combined earnings.

This means a director earning £30,000 from each of two companies pays Class 1 NICs on both earnings streams independently. In 2025/26, the primary threshold is £12,570 per employment. So each company deducts employee NICs on earnings above £12,570. The director pays NICs on £17,430 from each job, giving total employee NICs of around £2,092 per job (at 12%) for a combined £4,184.

If the same director earned £60,000 from a single company, they would pay NICs on £47,430 at 12% up to £50,270, then 2% on the excess. That works out at roughly £4,944 in employee NICs.

The director pays less NICs overall when earnings are split across two employments. This is legitimate. HMRC does not combine NICs across separate employments. But the director's employer (each company) also pays employer NICs at 13.8% on earnings above the secondary threshold of £9,100 per employment.

For a director with two companies, each company pays employer NICs on the director's earnings above £9,100. This can increase total employer NIC costs compared to a single employment.

Director-Specific Rules: Annual Earnings Period

Directors are treated differently from other employees for NIC purposes. For most employees, NICs are calculated on each pay period (weekly or monthly). For directors, NICs are calculated on an annual basis, even if they are paid monthly.

This matters because the director's annual earnings period means their NICs are calculated on their total earnings from that company over the whole tax year, not on each payslip. This can affect the timing of deductions.

For a director who works for two companies, each company uses the annual earnings period for its own payroll. The director's earnings from Company A do not affect NICs at Company B, and vice versa. But the director's combined earnings from both companies could push them into higher rate tax, which is why the tax code allocation matters.

Which HMRC Forms to File

Each company must file its own RTI (Real Time Information) returns for the director. The director will appear on both payrolls. HMRC's systems will link the two employments through the director's National Insurance number.

You must report the director's earnings and deductions on the following forms:

  • FPS (Full Payment Submission): filed each pay period, showing the director's pay, tax, and NICs. Each company files its own FPS.
  • EPS (Employer Payment Summary): filed to reclaim statutory payments or report employer adjustments. Not typically needed for a standard director payroll.
  • P60: issued to the director at year end by each company, showing their earnings and deductions from that employment only.
  • P11D: filed for benefits in kind. If the director receives benefits from both companies, each files its own P11D.
  • P11D(b): filed to report Class 1A NICs on benefits. Each company files its own.

The director will receive two P60s and must report both sets of earnings on their self assessment tax return (SA100). If they have benefits, each company's P11D details also go on the return.

What Happens at Year End

At the end of the tax year, HMRC reconciles the director's total tax and NICs across all employments. If the tax codes were allocated correctly, the director's total deductions should match their liability. If not, HMRC will adjust the director's tax code for the following year or issue a calculation (P800) showing any under or overpayment.

Directors should check their self assessment calculation carefully. The tax calculation on the SA100 will combine all employment income, dividends, and other income. If the PAYE codes were wrong, the director may owe additional tax or receive a refund.

For NICs, the annual reconciliation does not combine across employments. Each company's NICs are final at year end. The director cannot reclaim overpaid NICs from one employment against shortfalls in another.

Practical Example: Director With Two Companies

Let's work through a real example. Sarah is a director of two companies: her own consultancy Ltd in Bristol's Harbourside area, and a joint venture property company she set up with a partner. She earns a salary of £45,000 from her consultancy and £15,000 from the property company.

HMRC allocates her tax code as follows:

  • Consultancy Ltd: code 1257L (full personal allowance)
  • Property company: code BR (all earnings taxed at 20%)

At the consultancy, Sarah's tax is calculated on £32,430 (£45,000 minus £12,570) at 20%, giving £6,486 in income tax. Her NICs are calculated on £32,430 (£45,000 minus £12,570) at 12%, giving £3,891.60 in employee NICs. The consultancy pays employer NICs of 13.8% on £35,900 (£45,000 minus £9,100), which is £4,954.20.

At the property company, Sarah's tax is calculated on the full £15,000 at 20%, giving £3,000. Her NICs are calculated on £2,430 (£15,000 minus £12,570) at 12%, giving £291.60. The property company pays employer NICs on £5,900 (£15,000 minus £9,100) at 13.8%, giving £814.20.

Total tax: £9,486. Total employee NICs: £4,183.20. Total employer NICs across both companies: £5,768.40.

If Sarah earned £60,000 from a single company, her tax would be £9,486 (same) but her employee NICs would be higher at around £4,944. Her employer NICs would be lower at around £5,740. The difference is small but real.

Common Mistakes to Avoid

Three mistakes crop up regularly with PAYE for director with two companies:

1. Using the same tax code on both employments. If both companies use code 1257L, the director gets double the personal allowance. HMRC will later collect the underpaid tax, often through a code adjustment the following year. This can create cash flow problems.

2. Combining NICs across employments. Each employment is separate for NICs. Do not try to calculate NICs on combined earnings. Use the annual earnings period for each company independently.

3. Forgetting to file separate P11Ds. If the director receives benefits from both companies, each must file its own P11D and P11D(b). Missing one can trigger penalties.

When to Review the Setup

Review the PAYE arrangement whenever the director's earnings change significantly at either company. A pay rise at one company might push them into higher rate tax, requiring HMRC to issue a D0 code (40%) on the second employment instead of BR.

Also review when the director leaves one of the companies. The remaining company will need to have the full personal allowance allocated to it. The director should contact HMRC to request this change.

If you are setting up a new company and the director already works elsewhere, register the new company for PAYE and submit the director's details on the first FPS. HMRC will issue the appropriate tax code within a few days.

Final Thoughts

PAYE for a director with two companies is manageable if you follow the rules. Use the tax codes HMRC issues. Treat NICs separately for each employment. File accurate RTI returns. And make sure the director includes both employments on their self assessment.

If you are unsure about any aspect, speak to an ICAEW qualified accountant who can review the payroll setup for both companies. A small error in tax code allocation can lead to a large underpayment by year end.
