Most common mistakes in Finnish limited companies (and how to avoid them)
Running a limited company (Oy) in Finland is easier than many entrepreneurs expect. Unfortunately, many of the accounting issues I encounter are not caused by complex tax rules or unusual transactions. They are often the result of small mistakes that gradually become costly problems.
BUSINESS EXPENSES
As accountants working with small businesses, freelancers, consultants, and English-speaking entrepreneurs in Finland, we regularly see the same issues repeated. While most of these mistakes are easy to avoid, they can lead to penalties, missed tax deductions, inaccurate accounting records, and unnecessary stress.
In this article, we'll look at some of the most common mistakes made by Finnish limited companies and explain how to avoid them.
Paying salaries (including per diems and kilometer allowances) without processing payroll correctly and reporting to the Incomes Register
This is one of the most common and expensive mistakes. Many business owners transfer salary from the company's bank account to themselves or to an employee and assume that the payment can simply be treated as salary later. Unfortunately, salary payments in Finland must be processed through payroll and reported to the Incomes Register within the required deadlines.
Common situations
Salary is paid before payroll calculations are prepared.
Salary is reported weeks or months late.
Company owners pay themselves without running payroll.
Employee benefits are not included in payroll reporting.
Why this causes problems
Late payroll reporting can result in:
Late filing penalties
Additional administrative work
Incorrect tax withholding
Incorrect pension calculations
A common misconception is that the money transfer itself creates the salary. It does not. Salary payments should always be processed through payroll before or when payment is made.
Forgetting to file EU recapitulative statements
Many Finnish companies sell services or products to businesses located elsewhere in the European Union. The invoices may be issued correctly with reverse charge VAT treatment, but one important reporting obligation is often forgotten: the recapitulative statement.
Common situations
Consulting services sold to a company in Germany.
Digital services sold to a company in the Netherlands.
Goods sold to a VAT-registered company in Sweden.
Invoices issued correctly but no recapitulative statement submitted.
Why this causes problems
The Finnish Tax Administration requires separate reporting of many intra-EU B2B transactions. Failure to file these reports can result in penalties. In practice, many entrepreneurs only discover the issue after receiving a notice from the Tax Administration, often together with late-filing fees that could have been completely avoided. The risk increases when businesses start selling internationally without discussing VAT reporting requirements with their accountant.

Receiving business income into a personal bank account
This issue is more common than many entrepreneurs realise. Sometimes customers accidentally pay an entrepreneur personally. In other cases, payments are received through online marketplaces, payment providers, digital wallets, or EMI services and never make their way into the bookkeeping records.
Common examples
Income received through online marketplaces.
Customer payments received into a personal bank account.
Payments received via foreign payment platforms.
Revenue received through an app or online service not connected to the bookkeeping process.
Why this causes problems
Every business transaction must be included in the company's accounting records. If business income is not recorded:
Revenue may be understated.
VAT reporting may become incorrect.
Financial statements may be inaccurate.
Tax risks increase significantly.
One of the strongest habits an entrepreneur can develop is ensuring all business-related income flows through identifiable and regularly monitored business channels. If income is received elsewhere, it should still be properly documented and recorded in accounting.
Making business purchases without company details
Another surprisingly common problem involves purchases made for business purposes. Entrepreneurs often buy software subscriptions, online services, equipment, advertising, or office supplies using personal information instead of company information. While the purchase itself may genuinely relate to the business, the supporting documentation is often incomplete.
Common examples
Software subscriptions purchased without company details.
Business equipment purchased using only the owner's name.
Advertising subscriptions missing company information.
International service providers issued incorrect customer details.
Why this causes problems
For accounting and VAT purposes, invoices should generally contain the correct company information. This is particularly important when dealing with:
EU suppliers
Reverse charge VAT transactions
VAT deductions
Business expense documentation
Without proper company information, recovering VAT or justifying deductions can become significantly more difficult.
Not providing a VAT number when purchasing business services
This issue commonly affects businesses purchasing software and digital services from international suppliers. Entrepreneurs sign up for services such as:
Google Ads
Microsoft 365
Adobe
Canva
ChatGPT subscriptions
Hosting providers
Various SaaS platforms
but forget to provide the company's VAT number during registration.
Why this causes problems
When dealing with suppliers in other EU countries, VAT treatment often depends on whether the customer is a VAT-registered business. If the VAT number is missing:
Incorrect VAT may be charged.
Reverse charge treatment may not apply.
Additional correction work may be required.
VAT deductions may become problematic.
A good rule is simple:
Whenever your company is VAT registered and purchases business products or services, always check whether the supplier should have your company's VAT number.
Mixing personal and company finances
Although limited companies are separate legal entities, many entrepreneurs continue treating company finances as an extension of their personal finances.
Examples
Paying private expenses from the company account.
Using business funds for personal purchases.
Making undocumented transfers between personal and company accounts.
Losing track of shareholder loans.
Why this causes problems
These transactions often require:
Payroll treatment
Dividend treatment
Shareholder loan accounting
Additional bookkeeping work
The more personal and business finances are mixed, the more expensive and complicated accounting usually becomes.
Waiting too long before asking for advice
Many problems could be avoided entirely with a short discussion before taking action. Instead, entrepreneurs often seek advice after:
Signing contracts.
Hiring employees.
Registering for international VAT.
Paying salaries.
Making significant purchases.
At that stage, fixing mistakes is often more difficult than preventing them.
How to avoid these common mistakes
Most accounting problems are not caused by dishonesty or negligence. They happen because entrepreneurs are busy focusing on sales, customers, and business growth.
The easiest way to avoid unnecessary penalties and compliance issues is to:
Process salaries through payroll before payment.
Discuss EU sales and VAT reporting requirements early.
Keep business income separate from personal finances.
Ensure invoices contain correct company details.
Provide your VAT number when purchasing business services.
Maintain complete records for all transactions.
Ask questions before making significant financial decisions.
Our thoughts
Most accounting mistakes are surprisingly easy to prevent once you know where the risks typically appear. For Finnish limited companies, the most common issues are not complicated tax-planning questions. They are often basic administrative errors such as late payroll reporting, missing EU reporting, incomplete purchase documentation, or income that never reaches the bookkeeping records.
