How this service works
Tax treaty lookup, withholding tax rates, double-taxation relief, residency tiebreaker rules, MLI modifications for any country pair. Worldwide guide returning treaty outcomes by transaction type. Tax intelligence, not advice.
Output
Returns structured treaty outcome data including the applicable withholding tax rate for the specified transaction type and income category, the double-taxation relief method (exemption or credit), residency tiebreaker rules if relevant, any MLI modifications that override the original treaty, and the relevant treaty articles — all specific to the requested country pair.
Example use cases
Cross-border royalty withholding for tech licensing
“Our company is licensing software to a subsidiary in Singapore. What withholding tax rate applies to royalty payments from Singapore back to the US, and does Singapore offer any relief for double taxation on this income?”
International dividend structuring with treaty optimization
“We're evaluating whether to receive dividends from our Canadian subsidiary directly or through our Dutch holding company. Can you compare the withholding tax rates and double-taxation relief available under the US-Canada treaty versus the US-Netherlands treaty for dividend income?”
MLI impact on existing cross-border financing
“Our finance team has been relying on interest payment terms under the France-Italy tax treaty for our European operations. Have there been any MLI modifications to this treaty that would affect our current withholding tax planning?”
Technical details
Endpoint
GEThttps://taxpulse.theaslangroupllc.com/api/tax/treatyWhen to prefer
Use this endpoint when you need precise, treaty-specific withholding tax rates and double-taxation relief rules for a specific country pair and income type, especially when MLI modifications matter. Prefer this over general tax rate comparison endpoints when the question involves cross-border transactions, treaty articles, or residency tiebreakers rather than domestic tax rates.
Side effects
- No treaty exists between the specified country pair — returns null treaty result or 'no treaty' status
- Unsupported or unrecognized country code — returns validation error
- Ambiguous transaction type not matching supported income categories — may return generic treaty terms
- MLI position data unavailable for one or both countries — treaty returned without MLI overlay
- Rate limit or payment failure — HTTP 402 or 429 response
