Everything that matters about SME chart of accounts legal basis in Bülach
Whether you run a Sàrl, an SA or a sole proprietorship in Bülach, SME chart of accounts 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 SME chart of accounts
A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Bülach as anywhere.
The annual accounts (art. 958 CO) consist of the balance sheet, the income statement and the notes; they must be drawn up within six months of the year-end so the general meeting can approve them. A delay here cascades into the tax return and the final social insurance settlements.
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.
For SME chart of accounts, two dates lock themselves in every year: the January salary declaration and the general meeting within six months — everything else is planned around them.
A well-structured SME chart of accounts
Concretely, SME chart of accounts benefits from three tiers: balance-sheet accounts (classes 1-2) kept spotless for the closing, income accounts (classes 3-6) shaped for steering, and closing accounts (class 9) reserved for year-end entries. Each tier has its rhythm and its owner.
For a business in Bülach, the Sterchi/Käfer structure also eases benchmarking: banks and fiduciaries reason on those standard classes to situate an SME's SME chart of accounts.

Outsource SME chart of accounts 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 Bülach can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — SME chart of accounts splits very well.
Bülach: what changes, what does not
Bülach (postal code 8180, canton Zurich) applies the same federal rules as the rest of the country: what changes in Bülach are the cantonal counterparts — tax administration, compensation office, commercial register.
Federal deadlines do not move in Bülach: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 8180 changes nothing about those rules, only the sender's address.
Frequently asked questions
Which documents should be prepared for the year-end closing?
Bank and cash statements at the closing date, the inventory of stock and work in progress, final AHV/LPP/accident settlements, contracts signed or amended during the year, invoices straddling two years and the detail of accruals. With an up-to-date document archive, most of it is already there. The list is identical in Bülach: the CO dictates it, not the commune.

Both are defensible. Below CHF 500,000 of revenue, a sole proprietorship may keep simplified accounts itself.
