VAT return required documents in Romanel-sur-Lausanne without the stress: how it works
Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on VAT return in Romanel-sur-Lausanne: what the law requires, what can be automated, and when to delegate.
The Swiss legal frame for VAT return
A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Romanel-sur-Lausanne as anywhere.
For VAT return, 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.
Outsource VAT return or keep it in-house?
Outsourcing does not exempt you from understanding: an owner who can read the balance sheet and the income statement challenges the fiduciary better — and pays for advice, not re-keying.
A business in Romanel-sur-Lausanne can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — VAT return splits very well.
Swiss VAT: rates, threshold and filings
A VAT return is prepared, not endured: clean VAT accounts, one code per rate and a monthly variance check make the deadline trivial — for registered businesses in Romanel-sur-Lausanne too.
For an SME in Romanel-sur-Lausanne, electronic filing of VAT returns has been mandatory since 1 January 2025; the tax administration's online portal is also where extensions are requested and past periods consulted. Combined with accounts that prepare the return automatically, VAT return stops being a quarterly chore.
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 Romanel-sur-Lausanne) and internal (closing, general meeting within six months). Mixing them up is the leading cause of delays.
For VAT return, year-end is prepared in October: last invoices, investment decisions, provisions to assess — December is too late to act, January is for recording.
Romanel-sur-Lausanne: what changes, what does not
Sole proprietorship, Sàrl or SA in Romanel-sur-Lausanne: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Vaud.
Romanel-sur-Lausanne requires no special bookkeeping: the Code of Obligations applies at postal code 1032 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
Frequently asked questions
What is the difference between a limited and an ordinary audit?
The ordinary audit applies to companies exceeding, for two consecutive years, two of three thresholds: CHF 20 million balance sheet total, CHF 40 million revenue, 250 full-time positions. Others fall under the limited audit, and those with no more than ten full-time positions on annual average can opt out with all shareholders' consent. These federal thresholds do not depend on the registered seat — in Romanel-sur-Lausanne as anywhere.
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 Romanel-sur-Lausanne: the CO dictates it, not the commune.
Do you need a fiduciary for VAT 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 Romanel-sur-Lausanne.
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 Romanel-sur-Lausanne.
