Withholding tax for the self-employed in Moiry: rules, deadlines, best practice
Delegate, digitalise or do it all yourself? Around withholding tax in Moiry, every SME draws its own line. The reference points below — federal law, cantonal practice and lessons from the field — help you place the cursor well.
The Swiss legal frame for withholding tax
A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Moiry as anywhere.
Late books show from the outside: poorly calibrated tax instalments, provisional filings, slow answers to the bank. Staying current is also a matter of image.
Outsource withholding tax or keep it in-house?
Outsourcing withholding tax to a fiduciary frees up time and secures compliance; keeping it in-house preserves a continuous view and costs less in fees. The best answer is often hybrid: the company captures and digitises as it goes, the fiduciary supervises, closes the books and represents the company before the authorities.
For withholding tax, a quarterly 30-minute check-in with the fiduciary beats an annual marathon: questions get handled while they are small.
A Swiss SME's accounting calendar
The typical annual cycle: monthly or quarterly AHV instalments, VAT returns (quarterly under the effective method, semi-annual under the net tax rate), the final salary declaration in January, closing in the first half-year, then the tax return and the annual VAT reconciliation. Each link depends on the quality of the previous one.
For withholding tax, two dates lock themselves in every year: the January salary declaration and the general meeting within six months — everything else is planned around them.

Digitalising withholding tax: 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 Moiry as everywhere.
For an owner in Moiry, 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.
Moiry: what changes, what does not
Working with a fiduciary from Moiry no longer depends on geography: the documents of a business in Moiry are shared online, while the canton Vaud keeps its own deadlines for the tax return.
Federal deadlines do not move in Moiry: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1148 changes nothing about those rules, only the sender's address.
Frequently asked questions
How long must records related to withholding tax 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 Moiry can therefore archive fully digitally.
Do you need a fiduciary for withholding tax, 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 Moiry.
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 Moiry, family allowances follow the canton's rates.
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 Moiry: the CO dictates it, not the commune.
