Over the past 8 years I’ve leased/financed through BMW, Porsche, VW, and Audi and refinanced one through a local credit union and not once has there ever been any sort of income verification.
With an 800+ score you will have zero issues, assuming there’s nothing unusual with your credit profile or you’re not 20 years old and trying to lease a $150k car, etc.
Worst case scenario and they do ask for current income verification, just be honest and say you just started your company, haven’t paid yourself yet, etc. Ask if a 2019 tax return will work. Again the absolute worst thing that could happen is you just get declined, you’re not going to be charged with fraud or go to jail or any of the other nonsense being suggested above.
