Balance sheet preparation for masonry contractors in Wiler (Lötschen): the practical guide
Balance sheet preparation for masonry contractors in Wiler (Lötschen) rests on three pillars: federal law that applies across Switzerland, cantonal deadlines worth knowing, and tools that eliminate re-keying. This guide puts it all in order, fact by fact.
Year-end closing: how the mechanics work
The CO's accounting principles frame the closing: regularity, prudence and consistency of presentation (art. 958c CO), on the going-concern assumption (art. 958a CO). In practice, that means valuation methods kept constant from one year to the next — and documented whenever they change.
For balance sheet preparation, the golden rule is to discover nothing in January: every uncertainty (doubtful receivable, dispute, unsellable stock) must be identified before the closing date, not after.
The Swiss legal frame for balance sheet preparation
AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Wiler (Lötschen) with a clean audit trail sails through these exercises.
One simple principle drives balance sheet preparation: 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 Swiss SME's accounting calendar
January: salary declaration to the compensation office and salary certificates. End of February, May, August, November: quarterly VAT returns (effective method), each to be filed and paid within 60 days after the quarter ends. Within six months of year-end: approved annual accounts. Then: the tax return under cantonal deadlines, with extensions possible.
The useful reflex: date every obligation the moment it arises. An employee hired means AHV/LPP deadlines created; VAT registration means a filing cycle set; a closing date fixed means backward planning of the close. Well organised, the balance sheet preparation calendar fills itself.

Outsource balance sheet preparation or keep it in-house?
Splitting roles clearly avoids duplication: the company captures documents and approves payments; the fiduciary checks postings, closes the year and defends the file before the authorities. Each side does what it does best — and nobody keys the same invoice twice.
A business in Wiler (Lötschen) can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — balance sheet preparation splits very well.
Wiler (Lötschen): what changes, what does not
Working with a fiduciary from Wiler (Lötschen) no longer depends on geography: the documents of a business in Wiler (Lötschen) are shared online, while the canton Valais keeps its own deadlines for the tax return.
Federal deadlines do not move in Wiler (Lötschen): VAT within 60 days, salary declaration in January, 10-year record retention — postal code 3918 changes nothing about those rules, only the sender's address.
Frequently asked questions
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 Wiler (Lötschen).
What are the legal obligations for balance sheet preparation in Switzerland?
The foundation is the Code of Obligations: proper bookkeeping (art. 957a CO), annual accounts (balance sheet, income statement, notes) and 10-year retention of books and records (art. 958f CO). VAT applies from CHF 100,000 of turnover, and social insurance settlements from the first employee. Nothing is different in Wiler (Lötschen): federal law applies.
Do you need a fiduciary for balance sheet preparation, or can you do it yourself?
Both are defensible. Below CHF 500,000 of revenue, a sole proprietorship may keep simplified accounts itself. As soon as payroll, VAT and a closing with tax stakes are involved, professional support prevents mistakes that cost more than the fees. With a shared platform, the fiduciary does not even need to be in Wiler (Lötschen).
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 Wiler (Lötschen).
