Limitation on Benefits (LOB): How to Qualify for Treaty Benefits
Limitation on Benefits is the gatekeeper between your entity and reduced withholding rates. Every US tax treaty includes an LOB article (typically Article 22) that restricts treaty benefits to entities with genuine economic ties to the treaty country. If your entity fails LOB, the treaty rate does not apply — regardless of where the entity is organized.
LOB exists to prevent treaty shopping: routing income through entities in treaty-favorable jurisdictions without real economic substance there.
The 6 LOB Tests
An entity needs to satisfy one of these tests. They are not cumulative — passing any single test is sufficient.
1. Qualified Person Test (Individuals)
Individuals who are bona fide residents of a treaty country automatically qualify. This is why W-8BEN (for individuals) does not require LOB analysis, while W-8BEN-E (for entities) does.
Who passes: Any individual who is a tax resident of the treaty country.2. Publicly Traded Company Test
The entity's principal class of shares is regularly traded on a recognized stock exchange in either treaty country.
Who passes: Listed companies on NYSE, NASDAQ, LSE, TSX, ASX, etc. This is the simplest test for large companies — if you're publicly traded on a major exchange, you almost always qualify. Who fails: Private companies, regardless of size.3. Ownership and Base Erosion Test
Two conditions must both be met:
4. Active Trade or Business Test
The entity conducts a substantial active trade or business in the treaty country, and the income for which treaty benefits are claimed is connected to or incidental to that business.
"Substantial" is relative — the business activity must be proportionate to the income on which treaty benefits are claimed. An entity with 2 employees in the Netherlands claiming treaty benefits on $500 million of US dividends would not pass.
Who passes: Operating subsidiaries with genuine local business operations — employees, offices, customers, revenue. Who fails: Shell companies, passive holding structures, conduit entities with minimal local activity.5. Derivative Benefits Test
The entity's owners would have been entitled to equivalent or better treaty benefits had they received the income directly. This applies when the treaty between the owner's country and the US provides rates at least as favorable.
Example: A UK company owned by German residents claims US-UK treaty benefits. The US-Germany treaty offers the same or better rates. The German owners would have received the same benefits directly, so derivative benefits apply. Who passes: Entities owned by residents of countries with comparable US treaties. Who fails: Entities whose owners are in countries with no US treaty or worse rates.6. Competent Authority Discretion
If none of the above tests are met, the entity can request a discretionary determination from the tax authority (IRS for US treaties). The authority may grant benefits if it determines the entity's establishment, acquisition, or maintenance was not motivated by obtaining treaty benefits.
Who uses this: Last resort. The process is slow (12-18 months), uncertain, and requires substantial documentation.Which Test Is Easiest for Each Entity Type?
| Entity Type | Easiest Test | Notes |
|---|---|---|
| Publicly traded company | Publicly Traded | Nearly automatic if listed on a recognized exchange |
| Private operating company | Ownership + Base Erosion | Works if majority treaty-country owned and limited deductible payments abroad |
| Holding company (treaty-country owners) | Ownership + Base Erosion | Must demonstrate >50% treaty-country ownership |
| Holding company (non-treaty owners) | Derivative Benefits | Only works if owners are in countries with comparable US treaties |
| Subsidiary of treaty-country parent | Active Trade or Business | Requires genuine local operations |
| Investment fund | Publicly Traded or Derivative Benefits | Depends on fund structure and investor base |
| Special purpose vehicle | Competent Authority | Usually the only option for SPVs |
Failing LOB means:
1. 30% withholding applies — The entity cannot claim the treaty rate on US-source dividends, interest, or royalties
2. W-8BEN-E is incomplete — Part III (treaty claim) cannot be properly certified without LOB satisfaction
3. Withholding agent liability — If the agent applies a reduced rate without valid LOB certification, the agent is liable for the under-withheld tax
4. No retroactive fix — You cannot claim treaty benefits retroactively by restructuring after the fact
LOB in Practice
LOB analysis is not a one-time exercise. Ownership structures change, income patterns shift, and the relevant test may change over time. Best practices:
LOB vs. PPT
The US uses LOB. Most other countries use the Principal Purpose Test (PPT) introduced by the OECD Multilateral Instrument. The PPT denies benefits if one of the principal purposes of an arrangement was to obtain the benefit. It is subjective where LOB is objective.
For entities subject to both (some newer US treaties include a simplified PPT alongside LOB), both tests must be satisfied.
