No audits here, knock on wood.
I also don't push the limits of the law, or get into the 'gray' area very much. I don't take a home office exemption, even though I fully deserve one. I've read again and again that the HO write off is a big red flag. Not worth it for $14 in saved taxes, IMO. My books are pretty much iron clad, and I have receipts to prove it. Any mistake that is made would be a sheer mistake on my part, and not one that was made by trying to cheat them.
I think that the people who get into trouble with the IRS are the ones really, really pushing the gray areas, or the ones trying to outright cheat the IRS. Like the guys trying to write off a $28,000 Harley, 4 ocean cruises, and $14,000 worth of extravagant meals with 'clients'. Some of those people are really asking for trouble, especially if it crosses the line. KWIM?
Just be honest, and keep every single business receipt, even if it is for $1.54 for a pack of ink pens.
The federal tax isn't bad, IMO, based on the net at the bottom of the form, but the social security tax is a killer. Not to get into a political debate, but they say that SS won't even be around after 2028...and I'll have to be 70 before I can collect. Not a lot of fun sending them thousands of dollars, most likely, for nothing. With my health, I doubt that I even live to be 70; the average life span of someone with my health problem is 59.
The SSI tax is a crushing blow...and a soul breaker...each and every year.
As always, YMMV...and I don't know if I mentioned this, but I'm not a tax expert.
