Finland 2026: How to Update Commercial Contracts & Shareholder Agreements After Labour and Tax Reforms

The need to update commercial contracts in Finland in 2026 has never been more pressing. Labour-market reforms that took effect on 1 April 2026, introducing new flexibility for fixed-term employment contracts and reshaping dismissal, notice and re-employment rules, require immediate revisions to workforce-related clauses in commercial agreements, subcontracting arrangements and supplier contracts. In parallel, the Finnish Tax Administration’s 2026 tax-year changes alter deductibility rules and withholding mechanics, while the Finnish Patent and Registration Office (PRH) now mandates online filing for all trade-register entries as of 1 January 2026.

Together, these reforms create a narrow window for in-house counsel, CFOs and managing directors to audit, renegotiate and amend their commercial contracts, shareholder agreements and security documents before the 2027 financial cycle begins.

Executive Summary and Immediate Actions

Legal and finance teams operating in Finland face three concurrent reform streams that directly affect contract drafting and corporate governance. Here is a rapid triage of what requires attention and when.

• Labour reforms (effective 1 April 2026). The amended Employment Contracts Act now permits fixed-term employment contracts of up to one year without a separately justified reason. Dismissal thresholds, notice periods for temporary lay-offs and the scope of the re-employment obligation have also changed. Every commercial contract containing workforce, subcontractor or secondment provisions must be reviewed.
• Tax changes (2026 tax year). The Finnish Tax Administration has confirmed changes to deductibility rules and other tax items for the 2026 tax year. Pricing clauses, withholding mechanics, gross-up obligations and tax indemnities in commercial agreements need updating to reflect these shifts.
• Corporate administration and shareholder governance. PRH’s mandatory online filing regime (from 1 January 2026) affects change-of-control notification clauses and corporate filing warranties. Announced corporate-tax timing adjustments for 2027 should trigger renegotiation of shareholder agreement provisions related to distributions, earn-outs and exit valuations.

Prioritisation framework:

• Urgent (within 30 days): Audit and redline all employment-related contract clauses; update fixed-term templates; align HR processes with amended dismissal and notice rules.
• Near-term (within 90 days): Revise tax clauses in commercial agreements (gross-up, withholding, indemnities); update shareholder agreements where tax-triggered renegotiation thresholds apply.
• Monitor: Track 2027 corporate-tax timing announcements; prepare for potential covenant adjustments in financing and security documents.

What Changed in Finnish Law: A Source-Backed Timeline

Understanding the precise dates and legislative instruments is essential when updating commercial contracts in Finland in 2026. The table below maps each reform to its effective date and its immediate contract impact.

Key Labour Dates, 1 April 2026

According to the Ministry of Economic Affairs and Employment (TEM), the core labour-law changes allow employers to enter into fixed-term employment contracts of up to one year without requiring a justified reason, a significant departure from the prior regime. The government’s proposal, published by Valtioneuvosto on 15 January 2026, also reformed notice periods for temporary lay-offs and narrowed the scope of the employer’s re-employment obligation. These amendments to the Employment Contracts Act entered into force on 1 April 2026.

Tax and Corporate Administration Dates

The Finnish Tax Administration (Vero.fi) published a summary of all tax-year 2026 changes, including modifications to the deductibility of certain costs. Separately, PRH’s mandatory shift to online-only trade-register filings, effective 1 January 2026, means that any shareholder or corporate agreement referencing paper-based filing processes is now outdated. Industry observers expect the announced 2027 corporate-tax timing adjustments to affect deal structuring for transactions that straddle the 2026–2027 boundary.

Employment-Related Contract Updates: Fixed-Term, Dismissal, Notice and Re-Employment

The Finland labour law reforms 2026 have the broadest and most immediate impact on commercial contract portfolios. Any agreement that references workforce composition, subcontractor staffing, secondment terms or supplier employment obligations must be reviewed.

Fixed-Term Contract Clause Updates

Under the amended rules, employers may now conclude a fixed-term employment contract of up to one year without stating a justified reason (TEM guidance). However, restrictions remain on using successive fixed-term contracts to circumvent permanent employment obligations. The practical implications for commercial contracts include:

• Subcontractor and outsourcing agreements. Where contracts require a supplier to maintain a minimum staffing level, clauses should now reflect that fixed-term workers may be engaged more flexibly, but that consecutive fixed-term engagements of the same individual still carry compliance risk.
• Secondment and staff-augmentation contracts. Update definitions of “fixed-term assignment” to align with the one-year threshold. Remove any outdated references to mandatory justified-reason requirements for short-term placements.
• Workforce-warranty clauses. Where a party warrants compliance with employment law, update the warranty to reference the amended Employment Contracts Act provisions.

Sample clause, adapt to fact pattern and verify with Finnish counsel: “The Supplier shall ensure that all fixed-term employment contracts entered into in connection with the performance of the Services comply with the Employment Contracts Act (as amended, effective 1 April 2026), including without limitation the restrictions on successive fixed-term contracts with the same employee.”

Dismissal and Notice-Period Changes

The 2026 amendments also adjusted the threshold and procedural requirements for dismissals and modified notice periods for temporary lay-offs. For commercial contracts, this means:

• Termination-for-cause clauses. Review any provisions that tie contract termination to the counterparty’s breach of employment-law obligations. Ensure the referenced standards reflect the new dismissal thresholds.
• Notice-period alignment. Where commercial agreements reference statutory notice periods (for example, in service-level transition clauses), confirm the periods match the amended statutory schedule.
• Temporary lay-off provisions. Update any force-majeure or business-continuity clauses that reference lay-off procedures to reflect the new notice-period requirements.

Probation and Re-Employment Obligations

The scope of the employer’s re-employment obligation has been narrowed under the 2026 reforms. Probation-period rules remain governed by the Employment Contracts Act, and standard probation periods of up to six months continue to apply. For commercial contracts:

• Post-termination staffing obligations. Where an agreement requires a party to offer re-employment to displaced workers (common in outsourcing transitions), verify that the obligation aligns with the reformed statutory scope.
• Probation references. Clauses in HR-services or recruitment agreements that reference probation mechanics should be confirmed against the current statutory text available on Finlex.

Finland Tax Changes 2026: Contract Payment and Pricing Clauses

The Finland tax changes 2026 create a second, equally important set of contract-revision triggers. The Finnish Tax Administration’s published guidance for the 2026 tax year confirms modifications to deductibility rules and other items that directly affect how payments under commercial contracts are structured, invoiced and taxed.

Pricing, VAT and Invoicing Adjustments

Where contract pricing was calibrated to a specific deductibility regime, the 2026 changes may shift the economic balance between the parties. Practical steps include:

• Audit all fixed-price and cost-plus contracts for embedded tax assumptions, recalculate if deductibility rules have changed.
• Review invoicing templates to ensure VAT treatment aligns with the current regime.
• Where pricing mechanisms include a tax-cost component, add a repricing trigger tied to legislative changes (see the change-in-law section below).

Withholding and Gross-Up Clauses

Withholding obligations are a frequent source of commercial disputes. The 2026 changes underscore the need for robust gross-up clauses that allocate withholding risk clearly.

Sample clause, adapt to fact pattern and verify with Finnish counsel: “If any deduction or withholding is required by applicable Finnish law (including any change in law effective after the date of this Agreement) in respect of any payment under this Agreement, the paying party shall increase the payment so that, after making the required deduction or withholding, the receiving party receives a net amount equal to the amount it would have received had no such deduction or withholding been required.”

• Scope of gross-up. Define whether the gross-up covers only statutory withholding taxes or extends to new levies and surcharges.
• Exceptions. Carve out situations where the withholding arises from the recipient’s own tax status or failure to provide required documentation.
• Co-operation to mitigate. Include a mutual obligation to co-operate in minimising withholding through treaty claims, exemption certificates or filing elections.

Tax Indemnity and Co-Operation Obligations

Beyond gross-up mechanics, parties should consider standalone tax-indemnity provisions that address retrospective tax assessments and changes in the interpretation of existing law.

Sample clause, adapt to fact pattern and verify with Finnish counsel: “Each party shall indemnify the other against any additional tax liability, penalty or interest arising from a change in Finnish tax law or its interpretation that takes effect after the date of this Agreement, to the extent such liability relates to payments made under this Agreement, provided the indemnifying party has been given reasonable notice and the opportunity to contest the relevant assessment.”

Update Shareholder Agreements in Finland: Triggers and Drafting Priorities

The convergence of tax reform and corporate-administrative changes creates clear triggers to update shareholder agreements in Finland. Key renegotiation triggers include:

• Material tax change. Where a shareholder agreement contains a “material adverse tax change” or similar trigger, the 2026 deductibility adjustments and announced 2027 corporate-tax timing shifts may activate renegotiation or buyout rights.
• Distribution and dividend mechanics. Changes that affect the tax treatment of distributions should prompt a review of dividend-waterfall clauses, preferred-return calculations and tag-along or drag-along pricing formulas.
• PRH filing obligations. Shareholder agreements that reference paper-based trade-register filings must be amended to reflect mandatory online filing. Change-of-control notification clauses should specify the new electronic filing process and timeline.

Sample Shareholder Amendment Protocol

Industry observers expect the most efficient approach to be a structured amendment protocol rather than a full renegotiation:

1. Circulate a reform-impact memorandum to all shareholders summarising the 2026 changes and their effect on existing agreement terms.
2. Identify provisions that require mandatory amendment (statutory compliance) versus those that are commercially desirable to update.
3. Draft a short-form amendment agreement addressing the identified provisions, preserving all other terms.
4. Obtain the required consent threshold (check the SHA’s own amendment clause, typically qualified majority or unanimous consent).
5. File any required notifications with PRH via the new online portal.

Tax-Triggered Buyout Mechanics

Where a shareholder agreement includes put or call options triggered by tax-law changes, verify that the valuation methodology accounts for the 2026 reforms. Early indications suggest that earn-out and deferred-payment structures in M&A transactions closing in late 2026 or early 2027 will need to model both the current and announced corporate-tax rates to avoid disputes.

Change-in-Law, MAC and Price-Adjustment Clauses: A Drafting Playbook

One of the most common questions practitioners face is what contract clauses protect a business from future law changes. In Finland, the answer centres on three drafting tools: change-in-law clauses, material adverse change (MAC) provisions, and price-adjustment mechanisms. The contract change-of-law clause in Finland must be drafted carefully, because mandatory employment-law protections cannot be contracted away.

Practical Drafting Guidance

• Define “change in law” precisely. Specify the jurisdictions, types of law (statutes, regulations, binding guidance, tax rulings) and the trigger date. A broad definition that captures “any change in Finnish law or its interpretation” provides maximum protection but may face pushback in negotiations.
• Notice and renegotiation window. Require the affected party to provide written notice within a specified period (for example, 30 days of becoming aware of the change) and grant both parties a defined renegotiation period (60–90 days) before escalation or termination rights arise.
• Mitigation obligation. Include a duty on both parties to take commercially reasonable steps to mitigate the impact of the change before invoking repricing or termination.
• Interaction with mandatory law. State explicitly that the clause does not purport to override mandatory provisions of Finnish employment law or other non-waivable statutory protections.
• Dispute resolution. Specify whether change-in-law disputes are resolved by arbitration (commonly Finnish Arbitration Institute rules) or by the ordinary courts.

Sample clause, adapt to fact pattern and verify with Finnish counsel: “If, after the date of this Agreement, any Change in Law occurs that materially increases the cost of performance for either party, that party may, by written notice to the other within 30 days of becoming aware of such Change in Law, request a renegotiation of the affected commercial terms. The parties shall negotiate in good faith for a period of 90 days. If no agreement is reached, either party may terminate the affected services on 180 days’ written notice, without liability other than for services already rendered.”

Security, Pledging and Financing Implications in Finland 2026

The security and pledging landscape in Finland in 2026 requires attention on two fronts: the indirect effects of labour-law changes on borrower covenants, and the administrative impact of PRH’s online-filing mandate on security registrations and perfection.

Checklist for Lenders and Secured Creditors

• Financial covenants. Where loan agreements include EBITDA or workforce-cost covenants, model the impact of the new fixed-term flexibility on staffing costs and potential severance liabilities under the revised dismissal rules.
• Security registration. Confirm that all pledge and security registrations comply with PRH’s online-filing requirements. Review any existing agreements that reference paper-based filing or manual registration processes.
• Floating charges. For enterprise mortgages (yrityskiinnitys), verify that the charged assets description remains accurate given any operational changes triggered by the labour reforms (for example, a shift from permanent to fixed-term workforce that changes the asset base).
• Enforcement and insolvency interaction. Review enforcement mechanics in security documents to ensure compatibility with the amended re-employment obligations, an enforcement action that results in staff dismissals must still comply with the reformed (though narrowed) re-employment duty.
• Intercreditor provisions. Where multiple secured creditors share security, update intercreditor agreements to reflect the new online-filing timelines and any priority implications.

Commercial Contract Checklist Finland: A 12-Step Update Workflow

The following commercial contract checklist for Finland consolidates all action items from the preceding sections into a single workflow. Use it as an audit tool across your agreement portfolio.

1. Inventory all active contracts. Catalogue every commercial agreement, shareholder agreement, financing document and security instrument governed by Finnish law or involving Finnish operations.
2. Flag employment-related clauses. Identify all provisions referencing workforce composition, fixed-term hiring, dismissal, notice periods, secondment or subcontractor staffing.
3. Flag tax-sensitive clauses. Identify pricing formulas, withholding mechanics, gross-up obligations, tax indemnities and deductibility assumptions.
4. Flag corporate-governance provisions. Identify filing obligations, change-of-control notifications and shareholder-consent mechanics.
5. Prioritise by risk. Rank agreements by exposure: highest priority to those with workforce-related obligations, imminent renewal dates or active M&A timelines.
6. Prepare redline templates. Draft standard amendment language for fixed-term clauses, tax gross-up, change-in-law and PRH filing references.
7. Co-ordinate with HR and finance. Ensure legal redlines align with operational changes already implemented by HR (post-1 April 2026) and finance (2026 tax year).
8. Engage counterparties. Send reform-impact notices to contractual counterparties where renegotiation or consent is required.
9. Negotiate amendments. Use the clause templates in this guide as starting points; adapt to the specific agreement and counterparty.
10. Update shareholder agreements. Follow the amendment protocol outlined above; obtain required consent thresholds.
11. File with PRH. Complete any required trade-register filings via the mandatory online portal.
12. Diarise 2027 monitoring dates. Set review dates for announced corporate-tax timing changes and any further legislative developments.

Next Steps

The reforms detailed above represent the most significant set of concurrent legislative changes affecting Finnish commercial contracts in recent years. The window to update commercial contracts in Finland in 2026 is narrow, particularly for agreements with imminent renewal dates, active M&A timelines or workforce provisions that are already non-compliant with the 1 April 2026 amendments. Legal teams that act now will secure compliance, avoid disputes and position their organisations for the further changes expected in 2027. Explore the Finland practice area or the Business lawyer directory to connect with qualified Finnish counsel who can assist with jurisdiction-specific contract reviews and redline drafting.
