Construction companies have more moving parts in their tax situation than almost any other industry. You're dealing with long project cycles, heavy equipment purchases, specialized labor, cost of goods sold, multi-state work, and IRS scrutiny on classification of workers.

Most GCs we talk to are leaving significant money on the table — not because their CPA is doing something wrong, but because no one is running the proactive construction-specific strategy that's available.

Here are the four highest-leverage construction tax strategies for 2026.

1. S-Corp Election: The Most Underused Tool in Construction

Construction is one of the industries most likely to benefit from an S-Corp election, and one of the least likely to have made it. Why? Because construction profits can be substantial, and the self-employment tax burden on a single-member LLC in construction is significant.

If your construction business is netting $150,000 or more per year after costs, an S-Corp election could save you $15,000-$25,000 annually in self-employment tax. That's not a rounding error — that's a truck payment, a crew bonus, or a equipment upgrade.

The key is reasonable compensation. As a GC who's also the primary estimator, project manager, and salesperson, your salary should be defensibly high. The IRS knows construction owners often understate their personal labor value, so document your role and compensation carefully.

2. Section 179 and Bonus Depreciation: Equipment Is a Tax Advantage

Construction equipment is expensive and the tax code is generous. Section 179 allows you to expense the full purchase price of qualifying equipment in the year it's placed in service, rather than depreciating it over time.
