Frequently Asked Questions
Can construction workers deduct tools and equipment?
Yes. Under Section 179, you can deduct the full cost of tools and equipment in the year of purchase up to $1,160,000 in 2026 (for business use). This includes hand tools, power tools, and small equipment. Boots, hard hats, gloves, safety glasses, and other PPE are also fully deductible as ordinary business expenses. Clothing that is not suitable for everyday wear (like a specific uniform) is deductible; standard work clothes are not.
What is the per diem deduction for construction workers away from home?
If your job requires you to be away from your tax home overnight, you can deduct a standard per diem of $80/day for meals and incidentals (domestic rate). Transportation workers under the DOT may use $69/day. "Away from home" means you must sleep away from your principal residence to meet job demands. Day trips that don't require overnight stays do not qualify for per diem.
How does the W-2 vs 1099 distinction affect construction worker taxes?
As a W-2 employee, your employer withholds income taxes and pays half of FICA (7.65%). As a 1099 independent contractor, you owe self-employment tax (15.3% on 92.35% of net profit), must pay quarterly estimated taxes, but can deduct all business expenses on Schedule C. The net tax cost of being 1099 vs W-2 depends on your deductions β high expenses can make 1099 advantageous despite the SE tax.
Can construction workers deduct union dues?
Yes. Union dues are a deductible business expense for self-employed (1099) construction workers on Schedule C. For W-2 employees, union dues were deductible as a miscellaneous itemized deduction before 2018 but are currently suspended through 2025. For 2026, the status of this W-2 employee deduction depends on whether TCJA provisions are extended β consult a tax professional.
How do multi-state job sites affect my taxes?
If you work construction jobs in multiple states, you may owe income tax in each state where you worked. Each state uses an apportionment formula based on days worked or income earned in that state. You file a nonresident return in each work state and a resident return in your home state, receiving a credit for taxes paid to other states. Proper record-keeping of which days you worked where is essential.
