SME tax return for Sàrl companies in Duggingen without the stress: how it works

Whether you run a Sàrl, an SA or a sole proprietorship in Duggingen, SME tax return 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 tax return

Swiss accounting law has been unified in the Code of Obligations since 2013: the same bookkeeping rules (art. 957a CO) and retention rules (art. 958f CO — 10 years for books, vouchers and reports) apply regardless of legal form. SME tax return sits squarely within this frame, including for companies based in Duggingen.

Also worth knowing: accounts may be drawn up in the currency most relevant to the business; if that is not the franc, values must additionally be stated in CHF (art. 958d para. 3 CO). Internationally active companies gain books that match their economic reality.

Swiss VAT: rates, threshold and filings

Charging VAT is not a matter of style: the number, the correct rate, the tax amount — the tax administration checks the form as closely as the substance, including at SMEs in Duggingen.

For businesses in Duggingen, VAT is in practice the most audited tax: punctual returns consistent with the books markedly reduce the odds of a deep audit of SME tax return.

Year-end closing: how the mechanics work

The closing is prepared all year long: a monthly bank reconciliation and accruals tracked as you go turn the year-end into a formality, for businesses in Duggingen too.

The timetable is tight: accounts drawn up and approved by the general meeting within six months of the year-end. For SME tax return, chasing missing documents from January (bank statements, contracts, insurance settlements) avoids the last-minute sprint and auditor reservations.

Outsource SME tax return or keep it in-house?

The Swiss fiduciary market is dense and governed by professional practice: industry standards, business secrecy, civil liability. Compare offers on three concrete criteria — exact scope (data entry? closing? payroll? VAT?), a named contact person, and the tools used. It prevents year-end misunderstandings.

In Duggingen, as everywhere, the right collaboration rhythm follows the activity: monthly for payroll and data entry, quarterly for VAT, yearly for the closing and tax advice.

Duggingen: what changes, what does not

Working with a fiduciary from Duggingen no longer depends on geography: the documents of a business in Duggingen are shared online, while the canton Basel-Country keeps its own deadlines for the tax return.

Federal deadlines do not move in Duggingen: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 4202 changes nothing about those rules, only the sender's address.

Frequently asked questions

Can SME tax return be automated with AI?

Largely, yes: automatic document reading, posting suggestions, bank reconciliation via QR references and VAT exports. Human approval remains essential — AI prepares, the professional checks. That is exactly how MyFiducia.ai approaches SME tax return.

Do you need a fiduciary for SME tax return, 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 Duggingen.

How long must records related to SME tax return 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 Duggingen can therefore archive fully digitally.

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 Duggingen.
