Tell me about it!
At the company I work for (small, construction-based, income after expenses under $2.5M), for 2025 both my numbers and our CPA numbers matched EXACTLY. Tell me why, then, when we actually submitted them that the IRS came back and said that we were getting a refund of about $33k? I mean, I don't mind the refund and the owner was ecstatic, but WTF? Both an experienced amateur and a certified professional ran the numbers, came up with the same one, and the IRS still said WRONG! So confused.
