Tax advisory for e-commerce in Mels: rules, deadlines, best practice

Whether you run a Sàrl, an SA or a sole proprietorship in Mels, tax advisory 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 tax advisory

Whether a business sits in Mels or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for tax advisory. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.

The good news: the Swiss frame is stable and predictable. Structure tax advisory once — chart of accounts, document flow, calendar — and the same organisation pays off for years.

Outsource tax advisory or keep it in-house?

The scope goes down in writing: who enters data, who approves payments, who answers the tax office, who keeps the originals. Every “we'll see” at the start becomes a December misunderstanding — in Mels as elsewhere.

A business in Mels can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — tax advisory 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.

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 tax advisory calendar fills itself.

Year-end closing: how the mechanics work

The closing turns day-to-day bookkeeping into annual accounts: balance sheet, income statement and notes (art. 958 CO). Mandatory stops: accruals and deferrals, depreciation, commercially justified provisions, inventory of stock and work in progress, then VAT and AHV reconciliations.

For tax advisory, a closing checklist reused every year transforms the exercise: same steps, same checks, same documents — only the year changes.

Mels: what changes, what does not

Sole proprietorship, Sàrl or SA in Mels: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton St. Gallen.

Mels requires no special bookkeeping: the Code of Obligations applies at postal code 7325 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.

Frequently asked questions

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 Mels, family allowances follow the canton's rates.

How long must records related to tax advisory be kept?

Ten years from the end of the financial year concerned (art. 958f CO). Electronic retention is permitted if the integrity and readability of the records are guaranteed — a serious digital archive validly replaces paper binders. A business in Mels can therefore archive fully digitally.

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 Mels too.

How much does tax advisory cost in Mels?

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.
