What the policy did

Structural tax reform enacted under Santos II in response to the 2014-2016 oil-price collapse and to satisfy OECD accession-track conditions. Raised the general VAT rate from 16% to 19%, unified the corporate income tax (phasing out the CREE surcharge and replacing it with a single rate path toward 33%), introduced dividend taxation on individuals, created anti- evasion criminal penalties, modernised DIAN enforcement powers, and shifted the monotributo/simple regime for small taxpayers. Designed to replace revenue lost from the hydrocarbons sector and broaden the tax base.

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.

tax progressivity
fiscal.tax_progressivity
Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
increased · moderate
more progressive (higher top rates, wider spread, larger targeted credits)
Dividend taxation + anti-evasion + PIT bracket adjustments.
tax corporate
fiscal.tax_corporate
Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.
decreased · weak
lower corporate tax burden
Unified rate path lower than previous combined income+CREE burden.
spending level

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?".

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.
