Limited statutory audit in real time in Erlen explained simply
Swiss accounting law (art. 957 ff. of the Code of Obligations) sets a precise frame, yet day-to-day practice often stays fuzzy. This guide walks through what actually matters for a business based in Erlen.
Year-end closing: how the mechanics work
The closing is prepared all year long: a monthly bank reconciliation and accruals tracked as you go turn the year-end into a formality, for businesses in Erlen too.
A well-ordered closing file speeds everything up: bank statements at the closing date, a signed inventory, final AHV/LPP/accident settlements, new or amended contracts, and support for the accruals. Limited statutory audit in Erlen then finishes in days, not weeks.
The Swiss legal frame for limited statutory audit
AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Erlen with a clean audit trail sails through these exercises.
For limited statutory audit, the classic early mistake remains mixing private and business: a dedicated bank account and documented private withdrawals eliminate half the discussions with the tax office.
A Swiss SME's accounting calendar
Three families of deadlines shape the year: federal (VAT within 60 days, salary declaration in January), cantonal (tax return, extensions depending on the canton, including in Erlen) and internal (closing, general meeting within six months). Mixing them up is the leading cause of delays.
For limited statutory audit, two dates lock themselves in every year: the January salary declaration and the general meeting within six months — everything else is planned around them.

Outsource limited statutory audit or keep it in-house?
Outsourcing does not exempt you from understanding: an owner who can read the balance sheet and the income statement challenges the fiduciary better — and pays for advice, not re-keying.
A business in Erlen can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — limited statutory audit splits very well.
Erlen: what changes, what does not
Sole proprietorship, Sàrl or SA in Erlen: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Thurgau.
Erlen requires no special bookkeeping: the Code of Obligations applies at postal code 8586 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
Frequently asked questions
How much does limited statutory audit cost in Erlen?
It depends on document volume, the number of salaries and VAT complexity — no serious figure can be quoted without examining the file. Two levers cut the bill everywhere: digitised, well-filed receipts and software that prepares entries instead of having them re-keyed.
What are the current Swiss VAT rates?
Since 1 January 2024: 8.1% (standard), 2.6% (reduced — for example food and medicines) and 3.8% (accommodation). Returns must be filed and paid within 60 days after the period ends (quarterly under the effective method, semi-annually under the net tax rate method). These federal rates apply unchanged in Erlen.
When is entry in the commercial register mandatory?
A Sàrl and an SA only come into existence with their registration. A sole proprietorship must register from CHF 100,000 of annual revenue; below that, registration stays voluntary but adds credibility and protects the business name. Registration goes through the canton's commercial register office — for Erlen too.
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 Erlen.
