Limitation on Benefits (LOB)
Limitation on Benefits is an anti-treaty-shopping provision that restricts who can claim treaty benefits. It ensures that only genuine residents with real economic connections to a treaty country can access reduced withholding rates.
What Is Treaty Shopping?
Treaty shopping occurs when a resident of a non-treaty country routes income through an entity in a treaty country solely to access favorable withholding rates.
Example: A company in Country X (no treaty with the US) sets up a holding company in the Netherlands (which has a US treaty with 0% interest withholding). US-source interest is paid to the Dutch company, which passes it to Country X. Without LOB, the Dutch company claims the 0% treaty rate — even though the actual beneficial owner is in Country X.LOB provisions are designed to deny treaty benefits in these situations.
Where LOB Appears
LOB is primarily a US treaty feature. Nearly all US bilateral treaties include a detailed LOB article (typically Article 22). The IRS maintains Table 4 listing LOB provisions across all US treaties.
Most non-US treaties rely instead on the broader Principal Purpose Test (PPT) introduced by the OECD's Multilateral Instrument (MLI) in 2017.
| Approach | Used By | Mechanism |
|---|---|---|
| LOB (detailed) | US treaties | Multi-part objective tests |
| PPT (general) | MLI signatories (104 countries) | Subjective purpose test |
| Both | Some US treaties post-2006 | LOB + simplified PPT |
A taxpayer typically needs to satisfy one of these tests to claim treaty benefits:
1. Publicly Traded Test
The company's principal class of shares is regularly traded on a recognized stock exchange in either treaty country. This is the simplest test — publicly traded companies almost always qualify.
2. Ownership and Base Erosion Test
Two conditions must both be met:
3. Active Trade or Business Test
Treaty benefits are available for income connected to an active trade or business in the treaty country. The business activity must be substantial relative to the income for which benefits are claimed.
4. Derivative Benefits Test
Benefits are available if the company's owners would have been entitled to the same or better benefits had they received the income directly. This is designed for holding company structures where the ultimate owners are in treaty countries.
5. Competent Authority Discretion
If none of the above tests are met, either country's tax authority can grant benefits on a case-by-case basis. This is a safety valve but involves significant administrative burden and uncertainty.
Why LOB Matters for Withholding Rates
Every withholding rate shown on this site is subject to LOB qualification for US treaties. A displayed rate of 5% on dividends only applies if the recipient passes the applicable LOB test. If they don't, the full 30% statutory rate applies.
This is why we include the disclaimer on every treaty page: treaty rates require not just filing the correct form (W-8BEN-E), but also meeting the LOB requirements in the treaty.LOB vs. PPT
| Feature | LOB | PPT |
|---|---|---|
| Nature | Objective, rule-based | Subjective, purpose-based |
| Certainty | Higher — clear tests | Lower — depends on interpretation |
| Complexity | High — multiple tests | Low — one paragraph |
| Burden of proof | Taxpayer | Tax authority |
| Used by | US (bilaterally) | 104 MLI signatories |
