Electrical contracting has one of the mildest seasonal patterns in the trades. Unlike roofing, landscaping, or snow removal (which are weather-dependent), most electrical work happens indoors and can be performed year-round. New construction follows a spring-through-fall cycle in northern markets, but service calls (panel upgrades, outlet additions, troubleshooting, EV charger installs) continue through winter. The result is a relatively even revenue distribution with a mild 1.5-2x peak-to-trough ratio. This makes the standard equal quarterly payment method practical for most electricians. The annualized method provides modest cash flow benefit only in markets where new construction drops sharply in winter.

✓Key takeaway

Electrical contractor seasonal pattern:

Month	Revenue	Driver
January	$13,000	Service calls, small repairs
February	$13,000	Same, pre-spring bookings
March	$15,000	Early construction season
April	$18,000	Construction + outdoor projects
May	$20,000	Peak construction
June	$20,000	Peak construction + AC-related
July	$18,000	Construction continues
August	$18,000	Same
September	$17,000	Late construction season
October	$16,000	Shoulder season
November	$14,000	Pre-winter projects
December	$12,000	Holiday slowdown
Total	$194,000

Peak-to-trough ratio: 1.7x (May $20,000 vs. December $12,000) This is one of the mildest in any trade.

Equal quarterly payments work well because no quarter has dramatically less income than the others.

Set-aside: 22-25% of net profit per job

On a $300 service call with $60 in materials: net $240, set aside $53-$60
On a $3,000 panel upgrade with $900 in materials: net $2,100, set aside $462-$525

How should an electrician plan estimated taxes?

Hypothetical example

Round numbers. A solo master electrician. Year 2. Single filer. $200,000 revenue, $50,000 expenses, $150,000 net profit.

Quarterly income:

Quarter	Revenue	Expenses	Net Profit
Q1 (Jan-Mar)	$41,000	$12,000	$29,000
Q2 (Apr-Jun)	$58,000	$15,000	$43,000
Q3 (Jul-Sep)	$53,000	$13,000	$40,000
Q4 (Oct-Dec)	$42,000	$10,000	$32,000

No quarter is below $29,000 in net profit. The mildest quarterly swing is only 1.5x ($43,000 Q2 vs. $29,000 Q1).

Full-year tax (sole prop): $36,800

Equal quarterly payments: $9,200/quarter Every quarter’s net profit ($29,000-$43,000) easily covers the $9,200 payment. This is the simplest approach for most electricians.

S-Corp ($60,000 salary) changes the picture: Full-year tax as S-Corp: $30,500 Equal quarterly payments: $7,625/quarter

The S-Corp savings ($6,300/year) are meaningful because the high net profit creates a large FICA savings on the distribution portion.

Year 1 to Year 2:

Item	Year 1	Year 2
Revenue	$130,000	$200,000
Section 179 (van + tools)	$48,000	$0
Other expenses	$35,000	$50,000
Net profit	$47,000	$150,000
Tax	$8,500	$36,800
Increase		$28,300 (4.3x)

Year 2 prior-year safe harbor: pay 100% of Year 1 ($8,500) or 110% if AGI over $150,000 ($9,350). Even with the safe harbor, you’ll owe $27,450-$28,300 at filing. Set the full amount aside during the year.

EV charger revenue and tax impact: If EV installs grow from 20/year to 40/year:

Additional revenue: 20 x $2,000 = $40,000
Additional materials: 20 x $500 = $10,000
Additional net: $30,000
Additional tax: $30,000 x 30% (higher bracket) = $9,000

This $9,000 additional tax needs to be reflected in estimated payments. If the growth happens mid-year, the Q3 and Q4 payments should increase by $4,500 each.

Per-job set-aside:

Job Type	Revenue	Materials	Net	24% Set-Aside
Service call	$250	$40	$210	$50
Outlet/switch install	$200	$30	$170	$41
Ceiling fan install	$300	$50	$250	$60
Panel upgrade	$3,000	$900	$2,100	$504
EV charger install	$2,000	$500	$1,500	$360
Whole-house rewire	$12,000	$4,000	$8,000	$1,920
Generator install	$8,000	$4,000	$4,000	$960

Simple rule: set aside $1 for every $4 of net revenue (25%). This slightly over-saves (actual effective rate is closer to 22-24% with QBI deduction), but the buffer covers any unexpected income spikes and the excess becomes a refund.

Commercial vs. residential tax planning: Commercial electrical work (new construction, tenant build-outs) tends to be lumpier than residential:

A single commercial project might be $50,000-$200,000
Revenue recognition: as work is performed (for larger contracts)
Progress billings may be 30-60-90 day cycles
This creates timing gaps between work performed and payment received

If a $100,000 commercial job pays in three installments ($30,000, $40,000, $30,000) across Q2-Q4, but most of the work (and materials) are in Q2, the tax picture is:

Q2: $30,000 revenue, $50,000 expenses = -$20,000 (loss on this project)
Q3: $40,000 revenue, $10,000 expenses = $30,000 net
Q4: $30,000 revenue, $5,000 expenses = $25,000 net

The project is profitable overall ($100,000 revenue vs. $65,000 cost = $35,000 net), but the timing of revenue vs. expenses creates temporary losses that affect quarterly estimated taxes under the annualized method.
