#A sole proprietorship as easy as light entrepreneurship

With Truster's sole proprietorship (toiminimi) service, you run your business under your own Business ID (Y-tunnus), but your day-to-day stays just as effortless as for a light entrepreneur. When you order the service, we open a Business ID on your behalf — or fetch your existing one into our system — and automatically register your sole proprietorship for advance withholding and VAT. All you need to do is approve the suomi.fi authorization, which gives us permission to handle things for you. A new Business ID typically opens within 1–2 business days, and you can track the progress of your order right on the app's home screen.

You don't need your own bank account for the business. Your customer pays the invoice into Truster's client funds account, from which we withhold VAT, advance tax based on the tax rate you've set, and our service fee — and transfer the rest to your personal account as a private withdrawal. All the money that lands in your account is yours to use: you'll never face a situation where you have to pay part of your withdrawals to the tax authority afterwards.

Getting started is free, and under the commission model you pay nothing for months with no invoicing. If you already have a dormant Business ID or are switching to us from an accounting firm, we'll handle the transfer and any necessary registrations — your bookkeeping continues seamlessly.

#Why run a sole proprietorship with Truster?

Your own Business ID brings the benefits of entrepreneurship: you can take on assignments that require a Business ID — platform work and subcontracting, for example — and deduct the VAT on your own purchases. Behind the scenes, Truster keeps single-entry, cash-basis bookkeeping: income and expenses are recorded as they occur, and you track them in real time through the app's reports.

Official filings are taken care of for you: we prepare and pay your VAT returns according to your tax period, and file your annual business tax return (Form 5) by the deadline. You scan receipts with the app — every receipt is checked by us before the VAT and tax filings, so your bookkeeping holds up to scrutiny.

Maksuvahti automatically keeps watch over your invoices: it tracks payments, sends your customer payment reminders after the due date, and sends the invoice to collections if needed. You never have to chase payments yourself — your withdrawal is paid out as soon as the payment reaches us.

You get your money flexibly: normally, a private withdrawal is paid once your customer has paid the invoice. With HetiPalkka you get the funds even before the invoice is paid (5% extra fee), and with Pikamaksu the withdrawal lands in your account immediately after payment, with no waiting for bank processing days (€25).

#Taxes and VAT — how it works

You set a tax rate in the app, and we withhold advance tax at that rate from every invoice and remit the accumulated taxes to the tax authority on your behalf. You can track your income from the income statement and update the rate as often as you like throughout the year. If the Tax Administration has assigned you your own advance tax payments, set the rate in the app to 0% — this way taxes aren't paid twice.

We collect VAT from your invoices and report and pay it to the Tax Administration according to your tax period — sole proprietorships opened through us have a quarterly tax period. All our users are VAT-registered, which works in your favor: being registered lets you deduct the VAT on your own work-related purchases, such as a computer or tools. Returns go out on time even for periods with no activity.

#Protection and social security

Truster Turva brings insurance coverage to your work: liability insurance covers personal injury and property damage you cause on the job, legal expenses insurance covers legal costs from work-related disputes, and accident insurance protects against accidents at work. The insurance is valid whenever you invoice through Truster. Turva also includes an extensive contract library — for example, a ready-made assignment agreement template you can use to agree on the terms of a job in writing before work begins.

YEL pension insurance applies to every entrepreneur once the conditions are met: you're 18–68 years old, you've worked as an entrepreneur continuously for at least four months, and your estimated annual income from work exceeds the statutory threshold (€9,423.09 in 2026). Your YEL income determines your pension as well as your sickness and parental allowances. You can see your income directly from the app's income statement, and you can arrange your YEL insurance easily through Truster — if the income threshold has you wondering, our customer service will check your situation.

#Who is a sole proprietorship right for?

A sole proprietorship with Truster suits full-time entrepreneurs and anyone whose assignments require a Business ID — food couriers, delivery drivers and subcontractors, for example. It's a natural next step once your invoicing as a light entrepreneur becomes steady: you move from one Truster service to another, and your customers, invoices and history come along with you. And if you later want the money paid directly into your own bank account, our Own Account service gives you full control — while bookkeeping still runs automatically.
