Association accounting for e-commerce in Aadorf: what every SME should know
Association accounting for e-commerce in Aadorf raises the same questions for most Swiss SME owners: which obligations apply, which deadlines are running, which documents to prepare. This page covers the federal rules in force — without unnecessary jargon.
The Swiss legal frame for association accounting
For an owner in Aadorf, the question is never “do we need accounts?” but “at what level of detail?”. The CO sets the floor; the bank, the tax office and the shareholders set the rest.
For association accounting, 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.
Outsource association accounting or keep it in-house?
Responsibility stays with the client: the fiduciary executes with care, but the signed accounts bind the company. Understanding what you sign is not optional.
A business in Aadorf can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — association accounting splits very well.
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 association accounting, year-end is prepared in October: last invoices, investment decisions, provisions to assess — December is too late to act, January is for recording.

A well-structured SME chart of accounts
A chart of accounts gets documented: one description line per account (what, when, VAT) is enough for two people to post the same way. It is the quality manual of association accounting, valid in Aadorf as anywhere.
In an SME in Aadorf, the chart of accounts is also a delegation tool: clear posting rules let a non-accountant prepare most entries without error.
Aadorf: what changes, what does not
Aadorf (postal code 8355, canton Thurgau) applies the same federal rules as the rest of the country: what changes in Aadorf are the cantonal counterparts — tax administration, compensation office, commercial register.
Aadorf requires no special bookkeeping: the Code of Obligations applies at postal code 8355 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.

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 Aadorf.
Which social contributions does a Swiss employer pay?
AHV/IV/APG: 5.3% employer share (the same is withheld from the employee); unemployment insurance: 1.1% each up to CHF 148,200 a year; occupational pension (LPP) by age and plan (employer at least 50%); occupational accident insurance paid by the employer; family allowances by canton. For an employer in Aadorf, family allowances follow the canton's rates.
What are the legal obligations for association accounting 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 Aadorf: federal law applies.
