Slop Tax
What it is
Slop tax is the extra dollars a contractor bakes into your bid to cover the inefficiency of their own business. On top of man days plus material plus a reasonable markup, they’re pricing in the time they waste managing bad crews, the jobs they’ve underbid somewhere else, the marketing they haven’t paid for yet, and the admin work they can’t stay on top of. You didn’t cause any of that. You pay for it anyway.
It’s a close cousin of fear tax and fu tax. All three live on top of the real cost of the work. Slop tax is the one that has the least to do with your project.
Why it matters
Most contractors are great at the trade and terrible at running a business. Running a business is genuinely hard. A one-man operation is efficient because the guy is everywhere at once. The moment he hires a crew, he becomes a manager, and the man day formula math gets weaker because he’s not productive anymore.
Scaling further makes it worse. Now he’s got a project manager who’s worse at it than he is, managing guys who need more direction. That management tax compounds. You see it in bids that are 40% above the real math. That’s not a skilled-trade premium, that’s the operator paying down their inefficiency on your job.
How it shows up
Do the bid math before you respond. Man days times day rate plus material plus 20-30% markup is the floor. If the bid lands within 20% of that, you’re in a reasonable zone. If it’s 50% higher, you’re either looking at a fear tax, a fu tax, or a slop tax. Ask where the delta is coming from.
The fix is not haggling. Bid this against another crew who can price to the formula. The best contractors to work with are the ones just past “solo” and the ones using sub chunking to stay lean. Avoid the scaled-up shop that’s sending a green PM to your job. Their slop tax is built into everything.
When a bid comes in high and you cannot unpack it, walk. Thank them, keep their number, and call the next one. You are not obligated to fund somebody else’s operational chaos.
