Legal, accounting and fiduciary: law firms, notaries, fiduciaries and auditors. These firms are both targets and referrers: they domicile many companies and are the first to know of new registrations, making them a key sector for any supplier of software, insurance or services to SMEs.
This sector accounts for 2 % of companies classified in the canton of Aargau, against 3 % across Switzerland. 5 companies in legal, accounting and fiduciary services were registered in the canton of Aargau over the past 30 days, 12 over 90 days.
Aargau is the canton of energy and industry: power plants and electrical engineering (Baden, Aarau), mechanical engineering, plastics and logistics along the A1, food processing in the Fricktal. Its position between Zurich, Basel and Berne makes it a fast-growing residential canton with a steady flow of new registrations.
Legal and accounting activities gather 23,195 establishments and 90,633 jobs in Switzerland, alongside the 152,459 jobs of management consulting and head offices. It is a market of very small firms, indispensable to SMEs, and three regulatory shifts (OECD minimum taxation, the revised anti money laundering act, the transparency register) put it in motion in 2026.
NOGA division 69 covers law and notary offices, fiduciary firms, auditors and tax advisers. With 23,195 establishments for 90,633 jobs, average size is below four jobs: the sector is an archipelago of one to ten person practices, topped by the five large audit networks and the business law firms of Zurich and Geneva.
The sector cannot be separated from division 70 (head offices and management consulting), which counts 28,991 establishments and 152,459 jobs. Many fiduciary firms bill bookkeeping, business advice and company administration at once, and the statistical border between the two divisions is porous.
Geography follows the economic fabric and the tax map. Zurich dominates with 4,616 establishments and 24,198 jobs, ahead of Geneva (2,365 and 10,333), Vaud (2,064 and 7,809), Bern (2,043 and 8,591), Ticino (1,527 and 5,570) and Zug (1,033 and 3,577). Relative to population, Zug and Ticino show the highest practice densities in the country.
Growth is modest and very uneven. Division 69 jobs went from 87,518 in 2019 to 90,633 in 2024, about 3.6% over five years, far behind the 17.2% of management consulting (130,065 jobs in 2019, 152,459 in 2024). Ticino is the exception with a clear decline (6,340 jobs in 2019, 5,570 in 2024), a consequence of tighter rules on offshore structures.
Audit consolidation shows in the Federal Audit Oversight Authority figures: the number of licensed audit firms fell to 1,738 in 2024 against 1,926 the previous year, during the licence renewal cycle, while licensed individuals rose to 10,016. Many very small practices give up the licence rather than carry the quality and continuing education requirements.
Three regulatory projects shape demand. OECD minimum taxation applies through the Swiss supplementary tax since 1 January 2024 and the international supplementary tax since 1 January 2025, for groups above EUR 750 million of revenue. Above all, the revised anti money laundering act and the new act on the transparency of legal entities enter into force on 1 October 2026: according to FIDUCIAIRE|SUISSE, some 500,000 legal entities will have to report their beneficial owners.
The audit duty flows from the Code of Obligations: ordinary audit for large and listed companies, limited audit for the rest, with an opting out possibility below ten full time positions. The Federal Audit Oversight Authority licenses and inspects auditors, FINMA supervises regulatory audits, and the Federal Tax Administration governs VAT and withholding tax.
The legal profession falls under the act on the free movement of lawyers and the cantonal registers, with cantonal disciplinary supervision. Fiduciary firms acting as financial intermediaries must join a recognised self regulatory organisation, a requirement the new 2026 regime extends to a wider circle of mandates.
The umbrella bodies are EXPERTsuisse for auditors, tax and fiduciary experts, FIDUCIAIRE|SUISSE for SME fiduciary firms, and the Swiss Bar Association for lawyers, backed by the cantonal bars. They supply continuing education, the Swiss auditing standards and, increasingly, shared digital tools for their members.
Who buys what: practices buy professional software (accounting, payroll, mandate management, electronic signature), archiving and hosting compliant with Swiss law, professional liability cover, recruitment and continuing education. They are also multipliers: one fiduciary firm installs the accounting and invoicing tool at dozens of SME clients.
Signals to watch: the 1 October 2026 deadline triggers a wave of compliance work and self regulatory affiliations, licence renewals published by the oversight authority show which practices drop or take up audit work, and commercial register entries reveal practices acquired by groups.
How ciblr helps: target by canton the establishments with 3 to 19 jobs that form the core of the fiduciary market, where a single partner makes the buying decision, separate law firms from fiduciary firms by combining legal form and company name, and spot new entries to approach a practice before its software stack is frozen.
Of these 1 094 companies, the dominant legal forms are: Limited liability company (GmbH / Sàrl) (39 %), Public limited company (AG / SA) (32 %), Sole proprietorship (27 %). 105 were entered in the commercial register in 2025 and 2026, that is 10 % of the active base; 55 registrations in 2025. That is below the average of the three previous years (75 a year): the pace of registration is slowing.
Share capital is known for 786 companies (72 %): CHF 53 M combined, median company in the 20-100k band; 320 of them (41 %) have capital of at least CHF 100,000.
743 companies (68 %) are VAT-registered, a sign of real activity; 1 094 (100 %) have at least one registered director; 334 publish a general phone or email, 373 have a website verified by ciblr, and 31 run job postings on Job-Room.
SOGC publications in the last 90 days: 12 new registrations, 17 changes of directors, 17 relocations of seat, 18 other amendments.
