Where PSCs get caught out

Three areas HMRC
focuses on for PSCs.

Director-only companies look simple. One director, one payroll. But the compliance requirements are the same as any employer — and the personal exposure when things go wrong is significantly higher.

⚖️

IR35 status undocumented

Operating outside IR35 isn't enough — you need a contemporaneous record of why that determination was made, based on the actual engagement terms at the time. A verbal agreement doesn't survive an enquiry.

💷

Salary above the NI threshold

Many PSC directors still pay themselves a salary above the NI secondary threshold, creating unnecessary employer NI liability. The optimal director salary for 2026/27 leaves NI at zero — bookd. structures this correctly by default.

📋

RTI not filed or filed late

Even a director-only company must file RTI on or before each payment date. Late filing triggers automatic penalties. bookd. submits on time, every time — with the submission logged and the HMRC acknowledgement recorded.

📊

No payroll records at year-end

Your accountant needs P60, payslips, and employer payment records. If the payroll isn't being run properly, reconstructing it at year-end creates risk. bookd. builds the records as the year progresses.

🏗️

CIS if you take construction contracts

If your PSC operates in construction, CIS obligations may apply. bookd. handles CIS verification and deductions alongside director payroll — no need for a separate arrangement.

What bookd. handles

Everything a director PSC
needs. Nothing it doesn't.

  • Optimal director salary structuring — set at the NI threshold by default, documented with reasoning per year.
  • IR35 status recorded on every run — position, basis, and HMRC status locked in the SHA-256 audit pack.
  • RTI filed on time, every time — production-connected, operator-approved, HMRC acknowledgement logged.
  • P60 and year-end records — complete payroll records maintained throughout the year, not reconstructed at filing time.
  • SHA-256 locked audit pack per run — every salary payment evidenced, sealed, and immutable. Ready if HMRC ever asks.
  • HMRC PAYE agent on file — bookd. holds HMRC PAYE agent authority. Correspondence handled directly when needed.
  • CIS alongside director payroll — if your PSC takes construction contracts, CIS verification and deductions handled in the same engine.
  • Simple, fixed monthly fee — director-only payroll is straightforward. Pricing reflects that. No software subscriptions. No surprises.
