You work hard, profits are finally steady, and now the question hits: what’s the most tax-efficient way to pay yourself without tripping payroll rules, overpaying social taxes, or making your first audit a nightmare? This guide gives US and UK owner-managers a clean, side-by-side playbook for 2025 so you can choose the right mix of salary, dividends, pensions/retirement, and benefits; especially if your team or vendors sit offshore.
What this section covers
- Owner compensation options by entity type in the US and UK
- How FICA/self-employment tax compares to UK National Insurance (NI)
- When to use dividends/distributions vs salary
- Retirement schemes (Solo 401(k), SEP, workplace pension, SIPP) and who can contribute
- Benefits, deductions, and common traps for cross-border founders
Key definitions you will use (plain English)
- Salary (Payroll). Pay subject to withholding. In the US it attracts FICA (Social Security + Medicare) or self-employment tax. In the UK salary goes through PAYE and National Insurance (NI).
- Dividends / Distributions. Owner profit withdrawals. US tax depends on entity type; UK dividends are separate from salary and not subject to NI.
- Reasonable Compensation (US S-corp). The IRS expects S-corp owner-employees to take a market-rate salary before distributions.
- Workplace Pension (UK). Employer pension contributions for directors/employees; typically deductible for the company and not subject to employee NI. A SIPP is a personal pension you or the company can fund within UK limits.
- Solo 401(k) / SEP IRA (US). Owner-only retirement plans with high annual limits tied to W-2 wages (Solo 401(k)) or net earnings (SEP).

Strategy patterns that actually move the needle
US playbook (owner-managed, profitable, stable)
- S-corp split (salary + distributions).
- Pay a market-based W-2 salary for your role.
- Take periodic distributions once salary is in place. This may reduce exposure to self-employment tax compared with a default LLC, while keeping income tax on total profits.
- Keep a comp file: role description, market data, time records.
- Retirement first, then perks.
- Solo 401(k) usually beats SEP when you pay W-2 wages, because employee deferrals are not tied to the profit calc and can front-load savings.
- Add employer contributions up to annual limits once cash allows.
- Health and fringe benefits.
- Self-employed health insurance deduction may apply.
- For >2% S-corp owners, fringe benefit rules are special—track in payroll correctly (e.g., shareholder health).
- §199A QBI check.
- Test eligibility and wage/UBIA limitations. Your salary level affects the deduction; run the calc before year-end.
- State payroll and nexus.
- If your team works across states or offshore, confirm state UI and withholding obligations and contractor rules.
UK playbook (owner-managed limited company)
- Director salary at efficient band + dividends.
- Set salary around thresholds that secure a qualifying NI year while keeping NI cost efficient.
- Pay dividends on retained profits after corporation tax; dividends do not attract NI.
- Company-paid pension contributions.
- Employer pension payments for directors are typically corporation tax deductible and outside employee NI, subject to wholly-and-exclusively, annual allowance, and any tapering.
- A SIPP can be funded by the company or personally; plan around allowances.
- Benefits and P11D/Class 1A NI.
- Cash vs benefit trade-offs matter; some benefits trigger Class 1A NI.
- Use trivial benefits carefully and capture everything on P11D where required.
- Dividends admin.
- Keep board minutes, dividend vouchers, and interim accounts to support distributions.
Cross-border founders: keep these in view
- Tax residence and treaty ties. Your residence drives where you pay and how credits apply. Use the US–UK treaty tie-breaker if needed.
- Social security totalization. The US and UK have a totalization agreement; with the right certificate you can often avoid double social charges on the same earnings.
- Payroll where you work. If you physically work in both countries, you may trigger payroll in both unless the treaty and certificates are in place.
- Company vs personal contributions. In the UK, company pension contributions can be more NI-efficient than extra salary. In the US, Solo 401(k) limits depend on W-2 pay; too-low salary caps your deferral.
- Withholding and forms. Keep W-8/W-9, 1099/1042-S and UK equivalents correct for any cross-border payments.
- Reporting hygiene. FBAR/FATCA (US) and worldwide income rules (UK) still apply even if you operate through companies.

Example workflows you can copy
US S-corp monthly rhythm
- Run payroll at agreed reasonable salary.
- Post employer taxes and retirement contributions.
- Quarterly, declare owner distributions based on cash and projected tax.
- Maintain a reasonable comp memo and board acknowledgment.
UK Ltd monthly rhythm
- Run PAYE for director salary; pay RTI on time.
- Fund employer pension to planned schedule.
- Quarterly, assess profits and declare dividends with minutes and vouchers.
- File P11D/Class 1A where benefits exist.
Common traps (and how to avoid them)
- US: Paying tiny S-corp salaries with large distributions. The comp file should stand on its own.
- US: Missing state payroll registrations where remote staff sit.
- UK: Declaring dividends without sufficient distributable reserves.
- UK: Paying personal expenses through the company without correct benefit treatment.
- Both: Underfunding retirement because salary was set too low to allow desired contributions.
- Both: No board minutes or resolutions supporting key owner-pay decisions.
Quick checklist before year-end
- Salary set at the right thresholds for your plan (US FICA base tests; UK NI bands).
- Retirement contribution plan agreed and timed before deadlines.
- Board minutes and dividend/distribution paperwork complete.
- PBC trail ready: payroll reports, tax filings, pension statements, dividend vouchers, comp memo.
- Cross-border residency and totalization confirmed for the current year.
