Structure and tax help for locum solicitors

Locum and consultant solicitors hit a structure decision early in self-employment and live with it for years. Limited company, umbrella, or sole trader. There is no universal right answer — it depends on income, engagement mix, IR35 determinations, and what you want from PII and pension.

What we hear from locum + consultant solicitors

The questions and concerns that come up most often in a first conversation.

01

Should I incorporate or stay sole-trader?

Below roughly £80,000-£100,000 of sustained consulting income, the admin cost of running a limited company rarely beats sole-trader status. Above that, it depends on how many engagements sit outside IR35 and your need for tax-planning flexibility (non-working spouse, deferred income, retained earnings for reinvestment).

02

What does 'inside IR35' actually mean for me?

Since 6 April 2021, when the engaging firm is a medium or large client, the firm (not your PSC) determines IR35 status. If they issue an inside-IR35 SDS, PAYE-style deductions apply on your fees despite the Ltd-co structure. Net into your company; cannot extract as dividend tax-efficiently.

03

How do I handle PII on my own account?

Sole-trader and Ltd-co consultants typically need their own PII to the SRA Minimum Terms and Conditions. £2m minimum cover. Annual renewals around October. Premiums for solo consultants are generally £1,500-£4,000+ depending on practice area and claims history. Litigation-heavy consultants pay materially more.

04

What expenses can I actually claim?

Outside IR35: SRA practising certificate, PII, professional subscriptions, CPD, motor between engaging firms, accountancy fees, professional indemnity excess, office equipment under AIA. Inside IR35: very limited; restricted to the same items an employee can claim. The engagement structure determines what's claimable.

05

What about umbrella companies?

Umbrella employs you under contract of employment, runs PAYE on your earnings, deducts tax and NI, pays you net. Expenses very restricted. Convenient and low-admin but rarely the most tax-efficient option for sustained consulting income. Suits short-term work and low-volume locuming.

06

I work for multiple firms. What changes?

Different firms may issue different IR35 determinations for similar work. Travel between firms is deductible (not home-to-first-firm). Apportioning materials, motor and overhead by engagement matters for accurate tax. We map each engagement against the right structure.

How we work with locum + consultant solicitors

01

Structure comparison: Ltd vs umbrella vs sole-trader

We model your specific income mix against all three structures: take-home after tax + NI, administrative cost, PII availability, IR35 implications. Output is a one-page comparison with a recommended structure and reasoning.

02

Annual self-assessment for sole-trader consultants

All consulting income, expense claims, professional subscriptions, payment-on-account schedule, student loan plan if applicable. Filed inside the deadline. Receipts tracked via a shared bookkeeping system so you're not chasing them in January.

03

Limited company accounting for PSC consultants

Annual statutory accounts, corporation tax return, personal director self-assessment, PSC payroll for the salary leg, dividend administration, IR35 status tracking per engagement. We handle each component or just the parts you need.

04

IR35 status review per engagement

When a firm issues a Status Determination Statement, we review whether it's correctly issued. Most are; some are not. Where the determination is challengeable we support the appeal. Where it stands, we restructure the income flow to reflect the deduction.

05

Mortgage-ready accounts

Lenders want SA302s with consistent income for sole-trader consultants or 2 years of company accounts for Ltd-co consultants. We produce both inside 48 hours of request and work with the legal-sector-friendly mortgage advisers who lend on professional income.

Common questions

I'm a newly self-employed solicitor. Should I incorporate from day one?
Almost never on day one. Most new consultants earn below the threshold where Ltd-co structure pays back the admin cost. Start as a sole trader, register for self-assessment, file the first return cleanly. Re-look at incorporation after 12-18 months when your sustainable income level is visible. The wrong structure costs more in admin than the right structure saves in tax for the first year.
Do I need my own PII as a consultant solicitor?
Generally yes. If you're providing legal services under your own SRA practising certificate, you need PII to the SRA Minimum Terms and Conditions: £2m minimum cover from a qualifying insurer. Some engagement structures have the engaging firm's PII covering you; clarify this contractually. Most consultants carry their own.
If a firm says my engagement is 'inside IR35', what does it mean for my Ltd?
The firm (as fee-payer) operates PAYE-style deductions on your fees before paying your company. Your company receives the net amount. You can't extract that net as salary or dividend tax-efficiently because the tax has already been deducted at source. Similar effect to being a PAYE employee for that engagement, with the additional Ltd-co overhead. You can challenge the SDS if you believe it's wrong; you can't ignore it once a fee-payer is operating on it.
What's the difference between a consultancy agreement and a locum agreement?
Mostly terminology, but consultancy implies a longer engagement (often retainer-based) while locum implies covering specific gaps (parental leave, illness, peak workload). Both can be structured as self-employed or via PSC; both face the same IR35 considerations. The contract wording matters less than the working reality for status determination.
How does VAT work for a consultant solicitor?
Same as any other UK supplier of legal services: VAT registration required at £90,000 of taxable turnover on a rolling 12-month basis. Legal services are standard-rated at 20%. Disbursements (recharged) generally outside VAT scope if you act as agent rather than principal. Many consultants register voluntarily below the threshold to reclaim input VAT on costs.
