Everything that matters about annual accounts for construction companies in Mendrisio

Annual accounts for construction companies in Mendrisio 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.

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.

A company in Mendrisio that presents clean, punctual annual accounts gains credibility — with its bank, its suppliers and the tax administration.

A well-structured SME chart of accounts

Account labels deserve as much care as numbers: “Third-party fees” says nothing, “Fiduciary fees” and “IT fees” say everything. Meaningful labels cut posting errors and make dashboards readable without a glossary.

The chart of accounts is also the hinge to VAT: every revenue account carries its rate (8.1%, 2.6%, 3.8% or exempt), every expense account its input-tax right. Set those attributes once in the tool and every subsequent return becomes reliable.

A Swiss SME's accounting calendar

Three families of deadlines shape the year: federal (VAT within 60 days, salary declaration in January), cantonal (tax return, extensions depending on the canton, including in Mendrisio) and internal (closing, general meeting within six months). Mixing them up is the leading cause of delays.

An SME in Mendrisio that holds its calendar twelve months straight changes its position: fewer official reminders, easier extensions — and annual accounts stops being a source of worry.

Outsource annual accounts or keep it in-house?

Outsourcing annual accounts 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.

A business in Mendrisio can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — annual accounts splits very well.

Mendrisio: what changes, what does not

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

Federal deadlines do not move in Mendrisio: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 6825 changes nothing about those rules, only the sender's address.

Frequently asked questions

Do you need a fiduciary for annual accounts, 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 Mendrisio.

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 Mendrisio: the CO dictates it, not the commune.

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 Mendrisio.

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 Mendrisio, family allowances follow the canton's rates.
