Any taxes not owed, a seller merely file a tax return with the state, just like any other tax returns filed for extra taxes a government has with held. 

Suggest you check in with him/her on this additional service as your attorney is already intimately familiar with the file and you can often give them pre-authorized amounts to settle on vs trying to squeeze all the blood from that turnip.

If you continue filing taxes jointly the income you realize from your separate property will still need to be explained and redacted, regardless of the type of entity holding the real estate.

You can get in and talk to the mayor or city council to get a feel for what is going on plus voice your opinions. 

I'm going to reiterate what's already been mentioned above, but I'm going to actually give you examples of why it's relevant to you to find a U.S. tax professional.1 - You're going to need to file U.S. taxes once you have property down here, there's federal filings, state filings, and sometimes local filings too2 - Tons of tax treaties between the U.S. and Canada that are easy to miss and can cost you a lot of money (important one with rentals - effectively connected income - if the professional you talk to doesn't know what this is, run away)3 - The amount of days you spend in the U.S. needs to be tracked and if you go over a threshold, all of your worldwide income could be taxable by the U.S.4 - Selling real property means up to 15% of your sales proceeds might not be available to you for years (FIRPTA)5 - Lots of nuance at the state and local levels, which both want to take as much money from you as possibleMain takeaway here is that you should find a U.S. based tax person.

The short answer is: file form 1099-NEC. 

You might need to file 1099s if you used contractors or other people whom you paid for labor:https://www.biggerpockets.com/forums/51/topics/1167632-expla...
