Impact assessment of changes to the supplementary tax law

Impact assessment of the amendments to the top-up tax act

What's at stake: The outcome affects how quickly large corporate groups subject to the global minimum tax get a clear and predictable framework to work within, and how their administrative costs for complying with the rules develop.

Case texts and AI reasoning are AI-translated from the Swedish originals; the Swedish text is authoritative.

What the vote decides

The question is whether the government should carry out a combined impact assessment of the amendments to the top-up tax act, covering companies' administrative costs and possibilities for simplification, or whether it is enough to await the ongoing international work on the framework.

Yes Yes — the committee proposal

The committee notes that work on commentary to the OECD model rules is still ongoing and not yet complete, therefore finds no reason to change its earlier position on the matter, and expects the government to carry out the necessary follow-up and analysis of the framework and, if needed, come back with measures; the motion calling for an impact assessment is therefore rejected.

No No — the reservations

Reservation 1 (S, V, C, MP)

The reservation supports the amendments in the bill but points out that the top-up tax act was introduced very quickly, that the Council on Legislation and several consultation bodies criticised the legislation at the time for not being fully worked through, and that the complicated implementation risks undermining the purpose of the global minimum tax; it therefore wants the government to carry out a combined impact assessment of the amendments covering the regulatory framework, companies' administrative costs, and possibilities for simplification.

Summarised from the committee report. Party labels in the summary come from the report, not from the vote.

What each plan points to — and how the party voted

For each party: the vote its own election manifesto and party programme point to in this case, next to how the party actually voted. A plan can only point to Yes or No; a party can also abstain.

Plan vs actual vote

Every party, in chamber order: what its own plan pointed to, how it voted, and the reasoning behind both. Highlighted rows are where the two differ — but a vote that follows the plan is a result too, so the reasoning is there for every party.

The plan wants a simple, stable and solidaristic tax system where the richest pay their share, and sees intergovernmental cooperation as the way to regulate international large companies and stop profits ending up in tax havens.

Plan documents: party programme · 2022 manifesto

Reasoning and quotes

The plan wants a simple, stable and solidaristic tax system where the richest pay their share, and sees intergovernmental cooperation as the way to regulate international large companies and stop profits ending up in tax havens. A comprehensive impact analysis aimed at the global minimum tax actually working aligns with that. The plan says nothing about this specific regulation, however, so support is derived.

Planen vill ha ett enkelt, stabilt och solidariskt skattesystem där de rikaste betalar sin del, och ser mellanstatligt samarbete som vägen att reglera internationella storföretag och stoppa vinster som hamnar i skatteparadis. En samlad konsekvensanalys som syftar till att den globala minimiskatten faktiskt fungerar ligger i linje med det. Planen säger dock inget om just detta regelverk, varför stödet är härlett.

The plan drives forward for a global agreement on increased corporate taxation, and a minimum tax that becomes so complicated that it undermines its own purpose counteracts that commitment.

Plan documents: party programme

Reasoning and quotes

The plan drives forward for a global agreement on increased corporate taxation, and a minimum tax that becomes so complicated that it undermines its own purpose counteracts that commitment. At the same time, the plan wants good business climate and security for small business owners, which argues for administrative costs to be analysed and simplified. The requirement for a comprehensive impact assessment is therefore in line with the plan, which however does not state itself about precisely this regulations.

Original (Swedish)

Planen driver på för en global överenskommelse om ökad beskattning av företag, och en minimiskatt som blir så krånglig att den undergräver sitt eget syfte motverkar det åtagandet. Samtidigt vill planen ha ett gott företagsklimat och trygghet för småföretagare, vilket talar för att administrativa kostnader ska analyseras och förenklas. Kravet på en samlad konsekvensanalys ligger därför i linje med planen, som dock inte uttalar sig om just detta regelverk.

The plan stands behind global commitments against tax evasion and simultaneously wants companies to have clear rules of the game and for it to be simple to run and grow a business.

Plan documents: party programme

Reasoning and quotes

The plan stands behind global commitments against tax evasion and simultaneously wants companies to have clear rules of the game and for it to be simple to run and grow a business. A comprehensive impact assessment of the supplementary tax framework and its administrative costs does not contradict the purpose of the minimum tax but serves the requirement for thoroughly considered rules. However, the plan says nothing about the supplementary tax specifically, so the conclusion is derived and uncertain.

Original (Swedish)

Planen står bakom globala åtaganden mot skatteflykt och vill samtidigt att företag ska ha tydliga spelregler och att det ska vara enkelt att driva och växa i företag. En samlad konsekvensanalys av tilläggsskattens regelverk och dess administrativa kostnader strider inte mot minimiskattens syfte utan tjänar just kravet på genomarbetade regler. Planen säger dock inget om tilläggsskatten specifikt, så slutsatsen är härledd och osäker.

The plan wants to clear out the rule tangle for companies and reduce the administrative burden, especially for smaller companies.

Reasoning and quotes

The plan wants to clear out the rule tangle for companies and reduce the administrative burden, especially for smaller companies. A combined consequence analysis of the additional tax's regulations, companies' administrative costs and possibilities for simplification lies directly in line with that commitment. Taxes shall moreover be globally competitive and not harm jobs.

En samlad konsekvensanalys av tilläggsskattens regelverk, företagens administrativa kostnader och möjligheterna till förenkling ligger direkt i linje med det åtagandet. Skatterna ska dessutom vara globalt konkurrenskraftiga och inte skada jobben.

The plan requires a tax system that is as simple and transparent as possible and tax rules that are easy to understand for businesses, and that regulatory burden for small businesses decreases and that public decisions are analysed from a business perspective. A comprehensive impact analysis of the additional tax's administrative costs and simplification opportunities is a direct expression of these commitments.

The plan takes no explicit position on what the committee actually decided — often because the committee's reason was procedural. The stance is derived and fully cited, but it does not show the party broke a commitment.

The plan requires that the rules the state sets up for companies are long-term and that tax rules are designed as simply as possible, and that monitoring and cost control are important political tasks.

A comprehensive impact analysis of the additional tax with focus on administrative costs and simplification opportunities aligns directly with that commitment.

The plan's core commitment is deregulation and that existing rules shall be reviewed so that companies' administrative burden decreases.

Reasoning and quotes

The plan's core commitment is deregulation and that existing rules shall be reviewed so that companies' administrative burden decreases. A comprehensive impact analysis of the supplementary tax's regulation, company costs and simplification opportunities is exactly such a review. The plan is moreover critical of tax rules that deviate from the world and of EU taxes, which further speaks for scrutiny of the implementation.

Original (Swedish)

Planens bärande åtagande är regelförenkling och att befintliga regler ska ses över så att företagens administrativa börda minskar. En samlad konsekvensanalys av tilläggsskattens regelverk, företagens kostnader och förenklingsmöjligheter är precis en sådan översyn. Planen är dessutom kritisk mot skatteregler som avviker från omvärlden och mot EU-skatter, vilket ytterligare talar för granskning av implementeringen.
