Reason
Stated objective pending verification
Revenue
Amendment-level revenue contribution not reliably quantified.
- Rung 1
Observed change
Observed: A value or event as an official source records it, copied without calculation.- Collections for the tax heads affected are drawn on the story page, from URA's annual data books. Before and after is never presented as this amendment's effect.
- Rung 2
Official forecast
Official forecast: What MoFPED or URA said a measure would raise, or why it was made, before the year began.- MoFPED: UGX 25 bn expected in FY2026/27 (Excise duty on cooking oil raised from Shs 200 to Shs 400 per litre).[MOF-BS-2627, printed page 40, PDF page 44]
- Rung 3
Reported yield
Reported yield: What URA attributes to a measure after the year. An official attribution, not a causal estimate.Missing. URA's annual revenue reports read for the register attribute no yield to this measure. URA's measure-level policy tables, where they exist, would settle it (URA Research and Planning).
- Rung 4
Static or modelled estimate
Modelled estimate: A mechanical or model calculation, with every assumption shown.Missing. No estimate made. A static estimate needs the taxable base before the change (volumes or values by product), which the register does not hold.
- Rung 5
Causal estimate
Causal estimate: An effect identified by a stated research design against a comparison group.Missing. No study with a defensible identification strategy was found for this amendment.
- Rung 6
Wider impact
Interpretation: A reading of the evidence, by a named source or by this register.Missing. No source read for the register describes effects on prices, compliance cost, investment or equity.
What is known, what is uncertain, and what would settle it
- Known: official forecast.
- Uncertain: reported yield, static or modelled estimate, causal estimate, wider impact; and 1 open point below.

Consequences

What worked
No criterion graded effective on the evidence read.
What did not
No criterion graded ineffective or counterproductive on the evidence read.
