Real estate accounting for SMEs in Thürnen: what every SME should know
Whether you run a Sàrl, an SA or a sole proprietorship in Thürnen, real estate accounting eventually lands on your desk. Here are the practical reference points — legal basis, deadlines and common pitfalls — to decide with a clear head.
The Swiss legal frame for real estate accounting
Swiss accounting law has been unified in the Code of Obligations since 2013: the same bookkeeping rules (art. 957a CO) and retention rules (art. 958f CO — 10 years for books, vouchers and reports) apply regardless of legal form. Real estate accounting sits squarely within this frame, including for companies based in Thürnen.
One simple principle drives real estate accounting: every franc in or out must be explainable by a document, an entry and an account. All of Swiss accounting law fits inside that traceability requirement.
A well-structured SME chart of accounts
Nearly all Swiss SMEs rely on the standard SME chart of accounts (Sterchi/Käfer): classes 1 (assets) to 9 (closing), with revenue in class 3 and expenses in classes 4 to 6. Using this standard structure makes conversations with your fiduciary, auditor and tax administration far easier.
In an SME in Thürnen, the chart of accounts is also a delegation tool: clear posting rules let a non-accountant prepare most entries without error.
Digitalising real estate accounting: what actually works
Accounting digitalisation always follows the same path: capture documents at the source (photo or PDF upload), let automatic recognition extract supplier, amount, date and VAT, approve the proposed entries, then archive each document linked to its entry. Every step removes a re-keying — and therefore an error source.
The winning pair for real estate accounting: a single inbox (e-mail, scan, photo) and one simple rule — no document sits more than a few days without a proposed entry.

A Swiss SME's accounting calendar
The typical annual cycle: monthly or quarterly AHV instalments, VAT returns (quarterly under the effective method, semi-annual under the net tax rate), the final salary declaration in January, closing in the first half-year, then the tax return and the annual VAT reconciliation. Each link depends on the quality of the previous one.
For real estate accounting, two dates lock themselves in every year: the January salary declaration and the general meeting within six months — everything else is planned around them.
Thürnen: what changes, what does not
Sole proprietorship, Sàrl or SA in Thürnen: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Basel-Country.
Federal deadlines do not move in Thürnen: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 4441 changes nothing about those rules, only the sender's address.
Frequently asked questions
What is simplified bookkeeping and who can use it?
Sole proprietorships and partnerships under CHF 500,000 of revenue may limit themselves to recording income, expenses and assets (art. 957 para. 2 CO). Once over the threshold — or upon founding a Sàrl or an SA — full accounts with balance sheet, income statement and notes become mandatory. The CHF 500,000 threshold is assessed the same way in Thürnen.
Can real estate accounting be automated with AI?
Largely, yes: automatic document reading, posting suggestions, bank reconciliation via QR references and VAT exports. Human approval remains essential — AI prepares, the professional checks. That is exactly how MyFiducia.ai approaches real estate accounting.
Does MyFiducia.ai work for a business based in Thürnen?
Yes: the platform runs online, the rules applied are federal (VAT, CO, AHV), and the file can be shared with any fiduciary. A business in Thürnen manages its documents, VAT and exports exactly as anywhere in Switzerland.
How long must records related to real estate accounting be kept?
Ten years from the end of the financial year concerned (art. 958f CO). Electronic retention is permitted if the integrity and readability of the records are guaranteed — a serious digital archive validly replaces paper binders. A business in Thürnen can therefore archive fully digitally.
