The Tax Month · October 2026
Can Uganda tax what it can't see?
UN member states are negotiating proposed rules that could reshape which country gets to tax cross-border services. Uganda already has a domestic answer for some of those payments. The harder question is what it would take to see the rest.
A Ugandan company hires a foreign company to provide a service. The provider never opens an office in Uganda. The work happens partly or entirely outside the country. The payment crosses a border. The customer is in Uganda.
So where does the tax belong, and can Uganda's tax administration actually see the payment?
That second question is the real subject of this issue. The UN negotiations below are the trigger for asking it now, not the story itself.
The number
Uganda's August tax collections, against target
The ring splits August's target, UGX 2,976bn, into what arrived and what didn't.
Domestic revenue overall (taxes plus non-tax revenue) reached UGX 2,872.47bn against a UGX 3,238.15bn target (88.7%). Including grants, total government revenue was UGX 2,895.82bn against UGX 3,299.10bn (87.8%), leaving a fiscal deficit of UGX 708.85bn against a planned UGX 257.62bn.

The tax mix
Every major tax handle fell short in August
From the programme to the actual outturn, via each named shortfall, plus a residual the three named categories don't account for.
Scroll to follow the money from the programme down to what actually arrived.
Figures in UGX bn. Each floating bar is the change from the running total to its left; the two solid bars are the reported programme and outturn. The residual step exists because the three named shortfalls sum to more than the total shortfall MoFPED itself reports -- see the calculation register.
Programme
UGX 2,975.86bn
MoFPED's own monthly programme for August: what the government expected to collect in tax.
Indirect taxes
-UGX 170.39bn
The largest shortfall. Split between VAT (-UGX 136.01bn, on electricity, cement, soft drinks and hotels) and excise duty (-UGX 34.38bn, on beer, cooking oil and cement).
Direct taxes
-UGX 108.43bn
Only UGX 28.32bn of this is attributed by name, to corporate income tax on lower-than-expected firm profitability. The rest isn't itemised in the source.
International trade taxes
-UGX 49.36bn
Spread across import duties, excise on imports, VAT on imports and the import surcharge, all named, none individually valued.
Unexplained residual
+UGX 15.54bn
Add the three named shortfalls together and they overshoot the real total shortfall by this much. MoFPED's own table doesn't explain the gap, and neither do we; see the calculation register.
Outturn
UGX 2,663.21bn
What actually arrived. 89.5% of the programme; a shortfall MoFPED itself states as UGX 312.64bn.
Which category dominates the shortfall
These three categories sum to UGX 328.18bn, not the UGX 312.64bn total shortfall MoFPED itself reports. See the unexplained residual in the waterfall above and the calculation register.

Trade-tax components are named in the source but not individually itemised by value, shown here without invented figures.
The explanations above (weak manufacturing sectors, lower firm profitability) are MoFPED's own attribution in the source report, presented here as their reported reasoning, not independently tested by TaxIntellilytics Stories against underlying firm-level data, which is not publicly available.
The Ugandan rulebook
Uganda already taxes cross-border services, automatically for some of them
The Income Tax Act, Chapter 338, gives Uganda a domestic answer for the opening hypothetical, before any international rule changes. Three provisions do the work:
A non-resident deriving dividends, interest, royalties, rent, natural resource payments or a management charge from a Ugandan source is taxed on the gross amount at 15% (Income Tax Act, Chapter 338, Schedule 4 Part V, para. 1).
Where the payment is under a "Ugandan source services contract" (a contract whose principal purpose is performing services that give rise to Uganda-sourced income), the non-resident is taxed at 15% of the gross payment (s.84(1)-(2); rate at Schedule 4 Part V, para. 1). This is the provision most cross-border service payments would fall under.
A separate, lower-rate regime. A non-resident earning income from a digital service delivered over the internet, an electronic network or an online platform to a customer in Uganda is taxed at 5% of the gross amount (s.86(1); rate at Schedule 4 Part V, para. 3). Online advertising, data services, and services delivered through an online marketplace are named examples (s.86(3)).
For a services agreement with a non-resident that isn't already caught by section 84, the Ugandan party must notify the Commissioner General in writing within 30 days of entering the agreement, disclosing its nature, likely duration, the non-resident's identity, and the total amount payable. Failure to notify makes the Ugandan party personally liable for the non-resident's tax (s.138(1),(3)-(4)). This is the identification mechanism for exactly the kind of arrangement that would otherwise be invisible.
Legal basis: Income Tax Act, Chapter 338 (consolidated text current to 23 December 2024), ss.82, 84, 86, 138 and Schedule 4 Part V, from the Uganda Legal Information Institute / Laws.Africa consolidation. Read directly from the consolidated text, not a secondary summary. Whether a specific real transaction falls under s.84 or s.86 (or a tax treaty overrides either) depends on its exact facts, which this issue does not resolve. See the hypothetical below.
The UN rulebook
Three real drafts, none of them settled
UN member states are negotiating a proposed Framework Convention on International Tax Cooperation plus two early protocols: one on taxation of income from cross-border services, the other on preventing and resolving tax disputes. The process runs 2025 to 2027, with texts intended for the General Assembly in 2027. The co-leads' own draft texts from the Fifth Session are below, read directly rather than summarised secondhand.
Negotiating architecture established
The UN General Assembly establishes the negotiating architecture; the Intergovernmental Negotiating Committee (INC) begins sessions.
Click a point to open it. The broken marks at either end mean those two milestones aren't on the same scale as the dated cluster between them; only that cluster's own gaps, one day, then a two-week wait, are real.
Click a document to see what it actually says.
28 articles: objectives, principles and definitions; fair allocation of taxing rights; mutual administrative assistance; governance (Conference of the States Parties, subsidiary bodies, secretariat); and how the Convention relates to future protocols.
Article 11 (“Exchange of Information”) is enclosed in square brackets in the text, which means negotiators haven't agreed it yet. Article 20 explicitly anticipates that detailed operative rules, like the cross-border-services provisions below, sit in separate protocols rather than the Convention itself.
22 articles. Article 5 (“Fees for Services”) and Article 6 (“Automated Digital Services”) are the operative provisions for the kind of cross-border payment this issue is about.
Both articles cap the source country's withholding tax at “[ ] per cent of the gross amount,” an empty bracket, not yet negotiated. Article 6(4) lists automated digital services almost identically to Uganda's own Income Tax Act s.86(3): online advertising, user data, online intermediation platforms, digital content, cloud computing.
Six chapters, from general provisions and dispute prevention through to resolution mechanisms, consultations and reservations.
This draft is at an earlier stage than Protocol I. Even its article numbers are bracketed placeholders (“Article [II.1]”, “Article [III.2]”, and so on) rather than settled numbering.
The headline finding
The two provisions of Draft Protocol I that would actually apply to the cross-border service in this issue, Article 5 (fees for services) and Article 6 (automated digital services), both cap the source country's withholding tax at "[ ] per cent of the gross amount." The rate itself is an empty bracket. Uganda's own equivalent rates (15% and 5%) are already settled law. Try it below.

A US$100,000 payment: Uganda's law vs the UN's draft
A Ugandan company pays a foreign provider US$100,000. Not an actual taxpayer, not a real transaction. Choose a service type to compare what Uganda's settled law says against the equivalent UN draft provision.
Uganda -- law in force
15%
Income Tax Act, s.84
A "Ugandan source services contract" -- taxed on the gross payment, plus section 138's 30-day notification duty where s.84 withholding doesn't already apply.
UN draft -- negotiating text
rate left blank
Draft Protocol I, Article 5 ("Fees for Services")
The source country may tax fees for services, but the cap on that tax is written as “[ ] per cent of the gross amount” in the draft -- an empty bracket. Negotiators have not yet agreed the number.
Scenario: Consulting or professional service, delivered remotely. Illustrative legal pathway only -- exact treatment depends on facts and any applicable tax treaty. Not tax advice.
The signature idea
A taxing right is not tax revenue
A rule, whether domestic or international, can allocate a taxing right without the revenue ever being collected. Between the two sits a chain, and each link can fail independently of the others:
Click a link in the chain to see what it actually requires.
Identification
Can the administration identify the payer, the provider and the nature of the payment?
Sections 82 and 84 of the Income Tax Act already close most of that chain automatically for ordinary cross-border services. The withholding obligation sits with the Ugandan payer, so identification and collection happen at the same moment as the payment. Section 138 exists precisely because that isn't true for every arrangement: it is the disclosure mechanism for the gap.
What we don't know yet
- What percentage negotiators will eventually agree for Draft Protocol I, Articles 5 and 6. Both are literally blank brackets in the text as of 20 July 2026.
- No specific Uganda tax treaty has been checked against sections 82/84/86 for a real transaction; treaties can override the domestic rate or allocation.
- African Group and Uganda-specific interventions in the Fifth Session aren't attributed here. That requires reading the official transcripts, not summarised in this issue.
- Whether section 138 notifications and section 84 withholding are reconciled against each other administratively is not publicly documented, classified as not established from public evidence, not assumed either way.
- Whether or how a future adopted Protocol I would interact with Uganda's existing ss.82/84/86 (supersede, sit alongside, or require domestic implementing legislation) isn't addressed in the draft text itself and isn't analysed here.
