I am glad to see that I am not the only one struggling with this problem and ABB. I have been trying to explain to ABB support that their taxation setup need to be corrected. Our listing is in Quebec so there is Lodging Tax, GST and QST. Providing ABB with your taxation number means they will not collect the tax and remit it to you. But I have found, at least here in Quebec, that if you do not register they still are not collecting the GST and QST. After getting the run-around and the absurd suggestion to use the Resolution Center to collect the taxes I am resigned that I have to include the taxes in my pricing. I resolve the problem of providing the tax information to the guest by proving a separate invoice which will show the tax breakout.
Unfortunately, this also means the 3.5% Quebec lodging tax is being calculated on top of the tax that I must add to the nightly price.
None of these solutions are in keeping with the taxation rules here in Canada.
