Biggest refund mistakes? Oh, I’m the king of ‘em. Sitting in my Seattle apartment, rain smacking the window like it’s laughing at me, I just filed my taxes last week and—yep—screwed up again. Like, seriously, why do I think I’m smarter than the IRS website? My desk’s a disaster, papers everywhere, and the coffee from that overpriced café down the street tastes like regret when I realize I missed a deduction. I’m just a regular dude, moved out here from Ohio a few years back, and tax season always humbles me. Raw honesty: I’m a mess, but I’m learning, okay?
Like, I still cringe thinking about 2023 when I thought my home office deduction was a slam dunk. Spoiler: I measured the square footage wrong, and poof—hundreds of bucks gone.

Rushing Like a Maniac: My Biggest Refund Mistake Ever
Man, rushing through taxes is, like, the biggest refund mistake I keep making. Last year, wrapped in a blanket ‘cause my heater was acting sketchy, I hit submit at 1 a.m. and missed a fat credit for some eco-friendly windows I put in. The click of that button felt so good, but then—bam—regret hit like a wet Seattle gust. It’s weird, right? I tell myself every year to chill, but I’m all caffeinated and impulsive, thinking I’m a tax wizard.
Here’s the deal: Slow down. Print your return, take a walk, or, like, read it to your dog—I did that once, and he legit stared like I was an idiot.
