Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.
Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).

Income Tax Law 91 of 2005 under the Nazif cabinet roughly halved the top corporate and personal income-tax rates from 40% to 20% (with a 10% basic-rate band), broadened the base by tightening exemptions, and modernised tax administration. Compliance and self-assessment improved markedly and tax-to-GDP rose despite lower nominal rates, anchoring the supply-side phase of Egypt's late-Mubarak liberalisation.
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.
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?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
