They want to know what Airbnb is disclosing and to who, it's a reasonable request, like wise what are the FX charges and fees why can't we access them easily. Tax planning is complex, so owners and their accountants need to know what if anything is being disclosed by Airbnb. AirBnb its self is no stranger its self to tax avoidance, see this recent excerpt from a Guardian Newspaper report.
"It was revealed this week that Airbnb paid less than €100,000 (£90,336) in French taxes last year, despite the country being the room-booking firm’s second-biggest market after the US.
In response, the French economy minister, Bruno Le Maire, informed the national assembly that the EU’s Franco-German axis would be proposing a pan-European clamp down. “These digital platforms make tens of millions of sales and the French treasury gets a few tens of thousands,” the minister said, adding that the current setup was “unacceptable”.
This clamp down could affect all current hosts, particularly in France and Germany, so it's important to find out what is being disclosed now.
