Tax Strategy for trade contractors
Trades contractors deduct materials, tools, vehicles, insurance, and licensing, and the vehicle deduction is often the largest. A work van used exclusively for the business supports either the standard mileage rate or a full expense deduction including depreciation, and a dedicated trades vehicle makes the actual-expense method far more favourable than it would for a mixed-use car. Worker's compensation premiums and tools that fall under $2,500 are also deductible.
Trades income follows the construction calendar closely, with a hard winter slowdown and a summer surge. Quarterly income can swing by a factor of three between peak and off-peak, so base vouchers on the trailing twelve months and hold back more aggressively during the busy season rather than spending it.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.
