Online accounting for e-commerce in Wilen (TG): rules, deadlines, best practice

Online accounting for e-commerce in Wilen (TG) 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.

Digitalising online accounting: what actually works

Digitising does not mean hoarding PDFs: without the document-entry link, a digital file is as opaque as a box of archives — true in Wilen (TG) as everywhere.

For an owner in Wilen (TG), a dashboard only has value if the data is fresh: automating data entry means, first of all, buying up-to-date information about your own business.

A well-structured SME chart of accounts

Shareholder current accounts demand strict hygiene: every private withdrawal documented, interest at the rates accepted by the tax administration, and a clean-up at closing.

For online accounting, the right granularity is decisive: enough accounts to steer the business (margins by activity, expenses by nature), few enough that every entry finds its place without hesitation. The VAT accounts (input VAT, VAT due) deserve special care — they are the basis of the annual reconciliation.

QR-bills and friction-free collections

Technically, two routes coexist: the classic IBAN with an optional reference, or the QR-IBAN which requires a structured 27-position QR reference. Only the second route makes matching truly automatic — every payment carries the exact identifier of its invoice.

For an SME in Wilen (TG), receivables are an asset to manage: a weekly ageing balance, graduated reminders and a provision for doubtful cases — online accounting provides the numbers, discipline does the rest.

The Swiss legal frame for online accounting

AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Wilen (TG) with a clean audit trail sails through these exercises.

For online 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.

Wilen (TG): what changes, what does not

Wilen (TG) (postal code 9535, canton Thurgau) applies the same federal rules as the rest of the country: what changes in Wilen (TG) are the cantonal counterparts — tax administration, compensation office, commercial register.

For a business in Wilen (TG), that means VAT returns identical to anywhere in Switzerland, but a tax return and family allowances governed by the canton Thurgau.

Frequently asked questions

Do you need a fiduciary for online accounting, 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 Wilen (TG).

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 Wilen (TG), family allowances follow the canton's rates.

What are the legal obligations for online 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 Wilen (TG): federal law applies.

When must a business register for VAT?

As soon as its worldwide annual turnover reaches CHF 100,000 (CHF 250,000 for non-profit sports or cultural associations). Below that, voluntary registration remains possible and often makes sense to reclaim input VAT on investments. The threshold is federal: it applies in Wilen (TG) as everywhere in Switzerland.
