Sipoo · Uusimaa · Finland
A limited company since 01.04.2018 and in the Finnish Trade Register since 03.02.1983. We give Nordic companies fully compliant bookkeeping, corporate tax planning within the rules, payroll that meets Incomes Register deadlines, and management consulting grounded in their own numbers.
Business-to-business services only.Verify our registration
We keep the books, prepare the returns and hold the deadlines. Where a statutory audit is required, it is performed by an auditor your company appoints independently — we prepare the file and liaise, as the Tilintarkastuslaki 1141/2015 (Finnish Auditing Act) requires.
Bookkeeping, taxation, payroll and advisory sit together, so the corporate tax return is built from the same ledger that produced your monthly management report — not reconstructed from it months later.
Statutory bookkeeping and financial statements prepared under Finnish FAS, with IFRS reporting packages for group consolidation.
Corporate income tax returns, VAT registration and periodic filings, and lawful, documented tax planning within Finnish and EU rules.
Collective-agreement compliant payroll, Incomes Register reporting and employer obligations for Finnish and posted employees.
Budgeting, cash-flow modelling, entity structuring and board reporting for owner-led companies growing across the Nordics.
Move the figures to see which statutory obligations follow — audit requirement, VAT filing period, reporting deadlines and the bookkeeping workload behind them. Every output cites the act it comes from.

A workload band in hours, not a price. This estimator never quotes a fee, and it does not calculate a tax saving or a refund. Indicative statutory scope only, generated from the figures you entered. It is not tax advice, not a fee quote and not a guarantee of any outcome. Your actual obligations depend on your full accounts and are confirmed in writing after review.
Recommended engagement scope · Group
Full financial reporting with group or IFRS packages, audit file preparation and auditor liaison, and board-level reporting.
Audit test — Tilintarkastuslaki 1141/2015, chapter 2 section 2
Two or more of the three statutory criteria are exceeded, so the company must elect an auditor. Bokforingsbyra Lundstrom Ab prepares the audit file and liaises with that auditor; it does not perform the audit itself.
VAT position
Monthly is the default filing period. The return and the payment are due on the 12th day of the second month following the tax period. The standard Finnish VAT rate is 25.5% and the corporate income tax rate is 20%.

An accounting firm earns its place by being boring in the right places. Here is what that means in practice.
Every recommendation names the act and section it rests on. Where the correct treatment is genuinely open, we say so and prepare an advance ruling application rather than take a position we could not defend in a tax audit.
VAT on the 12th, Incomes Register within five days of payment, the tax return four months after the period, financial statements to PRH within eight. The calendar is ours to hold, and you hear from us before a deadline rather than after it.
The management report, the VAT return, the corporate tax computation and the audit file all come out of the same bookkeeping. Nothing is reconstructed at year end, which is where most surprises come from.
Your records and the enquiries you send through this site are stored on servers in the EU/EEA and seen only by our own staff. Retention periods are stated in the Privacy Policy and, once we are engaged, in the engagement letter.
We publish no client logos we cannot name, no success metrics we cannot evidence and no guarantees about tax outcomes. What we do publish is the register entry itself, so any visitor, client or advertising reviewer can confirm who they are dealing with in under a minute.
43 years in the register. Also registered as Tilitoimisto Lundström Oy and Lundström Accounting Ltd — parallel-language names of the same legal entity. Part of the Wulff Group (Wulff-Yhtiöt Oyj, Nasdaq Helsinki) since 16 February 2024.

The business has been in the Finnish Trade Register since 3 February 1983. It operated as the limited partnership Bokföringsbyrå A. Lundström Kb until 1 April 2018, when it was converted into a limited company and took its present name, Bokföringsbyrå Lundström Ab. Both dates appear in the public register under the same Business ID.
No. Under the Finnish Auditing Act (1141/2015) the party that keeps the accounts cannot issue the audit opinion on those same accounts, and Bokföringsbyrå Lundström Ab is not an audit firm. We prepare the audit file, answer the auditor’s requests and manage the timetable, while the statutory audit itself is performed by an auditor your company appoints independently.
No. Services are provided to businesses, associations and other organisations with reporting obligations in Finland. We do not offer consumer debt advice, consumer credit, personal investment advice or any service requiring a licence we do not hold.
It applies the published thresholds in Finnish law to the figures you enter and returns the statutory obligations that follow — whether an auditor must be elected under the Auditing Act, which VAT filing period applies, the reporting deadlines, and an indicative bookkeeping workload in hours. It does not quote a fee and does not calculate a tax saving or a refund.
One conversation, no fee and no commitment. You describe the company; we come back with the statutory obligations we can see and a written scope of what we would take on.
