A remodeler called in early December last year, pleased with himself. He’d “spent” $45,000 before year-end: a truck ordered, a deposit down on a mini excavator, and a stack of material invoices he planned to pay in January. He figured he’d knocked a big chunk off his 2025 tax bill.
He hadn’t. Almost none of it counted for the year he thought it did.
This is the gap a good CPA for home remodelers watches in November, not the following April. For a cash-basis contractor, a deduction in 2026 comes down to one thing: did the money actually move, and did the equipment actually go to work, before December 31. Ordering, promising, and planning to pay are not the same as paying. The calendar doesn’t care about your intentions. It cares about the date on the transaction.
Why timing is the whole game for contractors
Most home remodelers and trade businesses under the gross-receipts threshold file on the cash method. That method is simple and it favors you: you deduct expenses when you pay them and report income when you collect it. The 2025 law changes opened the cash method up to more residential builders, so more of you can use this timing to your advantage than could a few years ago.
The same rule that helps you also trips you up at year-end. On the cash method, a bill you haven’t paid is not a deduction yet, no matter how real the obligation is. The job cost is on your books. The deduction is not on your return. That is where a lot of contractors leave money sitting in the wrong tax year.
What “the money moved” actually means
A few rules decide the date, and they aren’t intuitive.
A check counts when you send it, not when it clears. Hand over or mail a check dated December 30 and it’s a 2026 deduction, even if the vendor deposits it in January.
A credit card charge counts when you charge it, not when you pay the card. Put $8,000 of materials on the business card December 28 and it’s deductible in 2026, even though you won’t pay that statement until late January. This is one of the most useful and most overlooked year-end moves a contractor has.
A deposit or a refundable retainer usually doesn’t count. Money you can still get back isn’t a payment, it’s a placeholder. The deposit on that excavator bought nothing, tax-wise, until the purchase was final.
Equipment has a second test: “placed in service”
Writing the check is only half of it when you’re buying equipment. To claim depreciation, Section 179, or bonus depreciation on a truck, a trailer, or a machine, the asset has to be placed in service by December 31. That means it’s ready and available to use in the business, not sitting on a dealer’s lot with your name on it.
A truck you paid for on December 29 but can’t pick up until January 4 was not placed in service in 2026. The excavator ordered but not delivered was not placed in service. The remodeler above lost the write-off on both, not because he didn’t spend the money, but because the equipment wasn’t working for him yet. If you’re timing a big equipment buy to land a deduction this year, the delivery-and-in-use date matters as much as the payment date. Bonus depreciation is now permanent at 100% under the 2025 law, which makes getting that timing right worth more, not less.
The payroll piece most owners forget
If you run an S-corp, your reasonable salary only helps this year’s return if the payroll actually ran this year. Same with wages to your kids working on the crew. The strategy is sound, but it’s the paycheck clearing, the money leaving the business, that locks in the deduction. A salary you “meant to pay yourself” in December does nothing. Get the final 2026 payroll run on the calendar now, not in the last-minute scramble the week of Christmas.
What to actually do before December 31
Pull your list of planned year-end expenses and sort each one by a single question: has the money moved, or will it move, before December 31? For anything you want in 2026, put a real payment on a real date. Charge the card or mail the check, and get the final payroll run scheduled. For equipment, confirm you’ll have it in hand and in use, not just ordered. For anything that can’t clear in time, stop counting it as a 2026 deduction and plan around the truth.
A CPA for home remodelers who’s actually doing the job has this conversation with you in November, while you can still move the pieces, not in March when they’re filing what already happened. The difference between a preparer and a strategist is whether anyone made that call before the year closed.
