Tax & Accounting for Construction & Trades

Contractors and subs face unique rules: method of accounting, subcontractor 1099s, equipment depreciation, and multi-state projects.

Accounting method matters

Completed-contract method defers income to project completion. Percentage-of-completion recognizes it as the job progresses. For long-duration contracts, method choice materially changes current-year tax.

1099-NEC for subcontractors

Contractors paid any subcontractor $600 or more must issue 1099-NEC by January 31. Missing 1099s create both penalty exposure and lost deduction risk in audit.

Equipment depreciation and Section 179

Trucks, trailers, heavy equipment, and tools qualify for Section 179 expensing up to annual limits plus bonus depreciation. Timing purchases with income spikes is a meaningful tax lever.

Common questions

Do I need workers' comp if all my labor is subcontractors?
Florida construction rules are strict. Misclassifying workers as 1099 when they're functionally employees creates serious exposure. We review classifications annually.
