Quote from @Mat Garcia: Can the Short-Term Rental landlords band together and letter-write/protest and force some type of vote or stop to this?

If not, even though you are a re pro, losses are passive & deductions are limited.There are 7 scenarios that will qualify as material, and you only need to meet one:*500 hours*Substantially all participation*> 100 hrs and at least 1/2*Significant participation*5/10 years*Personal service activity w participation in last 3 years*Continuous participationTo materially participate, you must be involved in the operations of the activity on a regular, continuous, and substantial basis.Once you pass the pro test, the material participation often comes along for the ride.You can elect to aggregate all rental real estate for purposes of measuring material participation under Sec. 1.469-9(g).Your time spent on all your rental properties (STRs don't qualify) counts as one activity, making it easier to materially participate.In order to make a strong case with your CPA and the IRS you need to document your hours.Best practice is an hours log where you are as specific as possible.

Social media (nextdooor, facebook, etc) had numerous threads/posts on what home owners could do to protest the fee (protest period ended early this month).  

A silent protest by IRS employees perhaps related to staffing...       

Also, keep in mind that you can protest your taxes. 

I would also recommend hiring a company to protest your taxes each year.

I recommend re-shopping insurance yearly with a landlord-savvy broker, raising deductibles if it makes sense, and always protesting property tax assessments, many investors win those.

Typically property appraisers tax a property  at 15 to 20% below market value specifically to avoid people protesting their taxes.  

File a claim for refund.Start or continue a protest.

@James Hamling why should I fear protesting.
