How much should an electrician set aside for taxes? A CPA's guide for NC & SC electrical contractors - self-employment tax, quarterly estimates, and how to owe less.

Short answer: most self-employed electricians should set aside 25–30% of net profit (what is left after business expenses) for taxes. If you are taxed as a sole proprietor or single-member LLC, lean toward 30%; once you elect S-corp status and plan your deductions, you can often run closer to 20–25%. The number is that high because you are covering three taxes at once — self-employment tax, federal income tax, and state income tax.
Division 26 CPA works only with electrical contractors in North and South Carolina, so here is how to size your tax set-aside and stop getting surprised in April.
Stack those together and 25–30% of net profit is a realistic working number for most electricians.
Set aside a percentage of the profit on every payment that hits your business account — not once a year. A practical routine: open a separate “tax” savings account, and each time you get paid, move 25–30% of the profit portion into it. When estimated taxes are due, the money is already there.
Example (illustrative): on $100,000 of net profit, a sole proprietor might owe roughly $25,000–$30,000 across self-employment, federal and state income tax. Your exact figure depends on deductions, filing status and entity — which is the whole point of planning.
The IRS expects self-employed electricians to pay estimated taxes four times a year — roughly April 15, June 15, September 15 and January 15. Skip them and you can owe underpayment penalties even if you pay in full at filing. We calculate these for clients so the payments are accurate and penalty-free.
The percentage is not fixed — good planning lowers it:
A good rule of thumb is 25–30% of net profit (income after business expenses). Sole proprietors and higher earners should lean toward 30%; electricians taxed as an S-corp with solid deduction planning can often set aside closer to 20–25%.
Yes. Self-employed electricians and electrical contractors generally must pay quarterly estimated taxes (around April 15, June 15, September 15 and January 15) to avoid IRS underpayment penalties.
Self-employment tax is 15.3% — 12.4% Social Security plus 2.9% Medicare — charged on your net self-employment income in addition to federal and state income tax. An S-corp election can reduce it.
North Carolina has a flat 3.99% individual income tax rate in 2026. South Carolina’s 2026 rates range from 1.99% to a top rate of 5.21%.
Capture every deduction (vehicle, tools, Section 179, home office), contribute to a SEP IRA or solo 401(k), consider an S-corp election, and plan year-round instead of scrambling at filing.
