Corporate tax reduction 28% → 22% and personal tax cuts

NOR·2014 – 2019·H-FrP minority, later H-FrP-V-KrF majoritycandidate

What the policy did

Staged reduction of the Norwegian ordinary corporate income tax rate from 28% (2013) to 27% (2014), 25% (2016), 24% (2017), 23% (2018) and 22% (2019), aligned with OECD peer-group trend and formalised in the 2016 cross-party tax settlement (skatteforliket). Parallel reductions to the personal income tax schedule top-bracket structure and adjustments to the wealth-tax (formuesskatt) valuation base for working capital. Rationale: improve corporate-investment competitiveness while preserving broad tax base; full ring-fence regime on petroleum income preserved separately.

Policy-content fingerprint — what this policy moved, on which axes

Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.

fiscal.tax_corporate

Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.

lower corporate tax burden

Six-point rate cut over five budgets; broad-based with limited base-broadening offsets outside the petroleum ring fence.

↓

tax progressivity

fiscal.tax_progressivity

Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).

decreased · weak

less progressive (flatter rates, compression, smaller credits)

Personal income tax bracket adjustments and wealth-tax valuation relief reduce effective top-quintile burden.

Empirical evidence — linked hypotheses

Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".

The 2000 Schroder corporate + personal tax reform package (top personal rate cut from 53 to 42 percent staged 2000-2005, corporate rate cut from 40 to 25 percent, capital-gains exemption on inter-corporate shareholdings) is associated with a 1.0 to 1.5 percentage point rise in the German top-1 pre-tax income share over 2000-2008 vs Eurozone synthetic control, but no measurable rise in aggregate output growth beyond Eurozone trend.

Chilean post-Pinochet tax progressivity reforms — Concertación-era Aylwin-Frei marginal-rate increases 1990-1995, Bachelet 2014 reform raising corporate rate from 20 to 27 percent + DTA tightening, Boric 2022-2024 reform attempts — produced gradual reductions in the Chilean top-1 pretax income share by at least 1.5 percentage points over 1990-2024 vs Latin-American synthetic comparator pool, with most of the level shift concentrated in 1990-2000 rather than the recent reform attempts.

Estonia's 1994 flat-tax 26 percent (subsequently reduced to 20 percent by 2015) and the unique 2000 corporate-tax reform (taxing only distributed corporate profits) produced a measurable rise in the Estonian top-1 pretax income share over 1994-2010 vs Baltic synthetic comparator (LVA, LTU), with the distributed-profit-only corporate regime channelling capital-income into top-decile reported income while reducing taxation of retained earnings.

Greek Memorandum-era tax hikes 2010-2018 (top marginal income rate raised to 45 percent, VAT hikes to 24 percent standard, ENFIA recurring property tax 2014, solidarity surcharge 2011-2019) raised the disposable-income Gini coefficient by at least 1.5 Gini-points relative to Eurozone- comparator synthetic control over the period, with the regressivity driven by VAT and property-tax incidence rather than income-tax progressivity.

Post-apartheid South African tax structure (top marginal income rate raised to 45 percent in 2017, capital-gains inclusion ratio raised 2012 + 2016, recurring property-tax effective burden via municipal rates) produced a measurable reduction in the South African top-1 pretax income share over 1995-2024 vs SADC synthetic comparator pool, with the recurring property-tax channel contributing more than the marginal-income-rate channel to the distributional effect.

Countries in the top quartile of Heritage lower-tax-burden score in 2024 have lower latest-available extreme-poverty headcount than bottom-quartile countries, consistent with free-market country policy regimes outperforming less market-oriented regimes on this outcome.

Progressive income-tax marginal rates (up to roughly 70% top rate) have been compatible with strong growth in post-war US 1945-1980 and Nordics, falsifying extreme-Laffer-curve positions.
