Top 2026/2027 Tax Deductions Specific to Plumbing, Electrical & Home Service Contractors
Every dollar of legitimate business expense you fail to categorize properly costs you 24% to 37%+ in federal and state income plus self-employment taxes. For Plumbing, Electrical & Home Service Contractors, our tax team focuses heavily on capturing and documenting: service vans, sewer cameras & press tools, parts inventory COGS, Jobber/dispatch subscriptions, and S-Corp reasonable compensation optimization, plus the Augusta Rule (Section 280A(g) — renting your personal residence to your S-Corp for up to 14 days/year tax-free for board/strategy meetings) and Accountable Plan home-office reimbursements.
When Should Plumbers & Electricians Elect S-Corp Status? (The $10,500–$21,000/yr Rule)
As a single-member LLC or sole proprietor, you pay the 15.3% Self-Employment Tax (Social Security & Medicare) on 100% of your net profit. Once your plumbers & electricians business consistently nets $70,000+ per year, electing S-Corp tax treatment lets you split your profit into a "Reasonable W-2 Salary" (via Gusto) and "Owner Distributions" that are completely exempt from the 15.3% self-employment tax—saving typical plumbers & electricians owners $10,500–$21,000/yr every single year.
