Mobile Notary and Process Server Self-Employed Tax 2026/27
Self-employed notaries public and process servers travel to clients and courts, with specific professional indemnity and Faculty Office fee questions. How 2026/27 Self Assessment applies.

Self-employed tax calculatorNotary practising certificate and seal
A notary public must hold an annual practising certificate issued by the Faculty Office to legally notarise documents — this fee is directly necessary to trade and is generally allowable. The notary's official seal, embossers, and the specific registers of acts required by regulation are also allowable equipment and record-keeping costs.
Professional indemnity insurance
Given the legal weight notarised documents carry (often for use internationally, in property transactions, or in legal proceedings), professional indemnity insurance is effectively mandatory for a practising notary, and the premium is a standard, fully deductible business expense.

Self-employed tax calculatorProcess servers and travel
Process servers — who deliver legal documents (claim forms, court orders, statutory demands) to individuals, often at addresses that require several attempts — typically cover significant mileage across a working week. Vehicle costs are claimed via the simplified mileage rate (45p/25p) or a proportion of actual running costs, not both for the same vehicle, chosen consistently — and given how central travel is to this specific trade, it's worth estimating both methods carefully before choosing.
Working through solicitors and agencies
Both notaries and process servers frequently take instructions via solicitors' firms or specialist agencies rather than directly from the end client, sometimes with a referral or agency fee deducted before payment reaches the practitioner. Recording the gross fee as income and the referral/agency deduction as a separate allowable expense (rather than only recording the net amount received) keeps a cleaner audit trail and makes it easier to reconcile income against invoices if HMRC ever asks questions.
