High-quality accounting brings transparency and gives management a clear overview of the company’s business and financial situation. Your team can now focus entirely on their work and bring home even more significant results.


Payroll Services in Finland

As the employment regulations, requirements and agreements are country-specific and have the tendency of changing rapidly, extensive hands-on local expertise is required.

VAT + Employer registration in Finland

Foreign businesses selling goods or services subject to VAT within Finland, are liable for VAT and need to be registered in the Finnish VAT register.

Company establishment in Finland

Setting a company in a foreign country is always a challenge: specific legal forms to be considered, different administrative procedures, many documents that need to be filled in or delivered. We look after your new company in Finland: form the legal body of the company and conduct all the necessary registrations.


Taxation services in Finland

On many occasions, Tax Advisory at Leinonen, through our partners in the field, is linked to accounting services. The taxation of international businesses changes frequently and is somewhat difficult to comprehend, even if the company is operating in merely one country. No need for you to worry though, we are here to assist you.

Frequently Asked Questions.

The first thing you should do is send us an email so we can schedule a meeting or a call. We would like to know more about your business and to discuss the scope of your needs: number of transactions that move through your account each month, annual revenue, the number of clients that you have, the number of employees that are on the payroll etc.

Additionally, we send you a questionnaire that helps us map your needs and requirements. Based on this information we are able to compile an offer. Once we understand how the process works for you currently, we can suggest improvements and how to best move forward with outsourcing.

Please remember that we are always pleased to meet and negotiate the offer as well as agreement conditions and other details. Our consultation is complimentary so you can learn more about our expertise and services.

We provide our services according to our clients’ needs, so there is no necessity to outsource entire accounting and payroll. In fact, sometimes it makes more sense to just outsource some processes or functions.

For example, you can have a junior accountant within your company taking care of day-to-day tasks and documentation, while Leinonen accountants execute general ledger or tax functions, money transactions and reporting. The complexity of the outsourced services really depends on your demand.

We can work with our own as well as the client’s preferred software. Most frequently we use softwares like Finago Procountor, Briox, Directo and Netvisor for accounting and Mepco HRM for payroll.

In every country, we provide services in accordance with the local laws and regulations. We follow the European GDPR regulation. To guarantee the maximum level of privacy we have internal group auditing practices and encrypt most of the handled documentation.

We serve both local and international clients from single-person companies to multi-billion dollar international companies. It can be said that many of our clients are somewhat involved in international trade.

A typical case would be a foreign-owned business, where the foreign owner of the local subsidiary wants to follow the local laws and regulations. They would like to hand accounting over to a trusted partner who is an expert in those laws and regulations. This way they can focus on their business, while Leinonen takes care of accounting, taxation and reporting formalities.
