ATM operation isn’t classified as a specified service trade or business (SSTB) under IRC 199A. Owning and operating ATMs is equipment ownership and cash logistics, not consulting, financial advisory, or any enumerated SSTB category. The full 20% QBI deduction is available at all income levels. The ATM business has a unique tax profile because it sits at the border between active and passive income. If the owner personally manages locations, loads cash, performs maintenance, and negotiates placement contracts, the income is active business income. If the owner simply buys machines and hires someone else to handle everything, the income may be reclassified as passive under IRC 469, which limits loss deductions.

✓Key takeaway

ATM business entity structure:

SSTB classification: NOT an SSTB. ATM operation is equipment ownership, cash logistics, and merchant services. Not financial advisory, consulting, or banking. The owner doesn’t provide financial advice; the machine dispenses cash mechanically.

Revenue model:

Surcharge fee per transaction: $2.50-$3.50
Transactions per machine per month: 150-400 (location dependent)
Revenue per machine per month: $375-$1,400
Average: 200 transactions x $3.00 = $600/month per machine
10 machines x $600 = $6,000/month ($72,000/year)
20 machines x $600 = $12,000/month ($144,000/year)
Interchange fee: $0.50-$1.00 per transaction (additional, from the cardholder’s bank)

Costs per machine:

Machine purchase: $2,000-$3,000 (used) or $3,000-$8,000 (new)
Installation: $200-$500
Monthly processing fees: $25-$50
Cash loading cost (vault cash interest or opportunity cost): varies
Location rent/commission to merchant: $0-$200/month or 30-50% of surcharge
Insurance per machine: $50-$100/year
Maintenance and repair: $100-$300/year
Network connectivity: $20-$40/month

Net margin per machine:

Gross revenue: $600/month
Location commission (40%): ($240)
Processing fee: ($35)
Cash loading labor: ($50)
Network/communication: ($30)
Maintenance reserve: ($25)
Net per machine: approximately $220/month ($2,640/year)
Payback period: $3,500 machine / $220 per month = 16 months

Active vs. passive classification: This is the critical tax question for ATM businesses:

Active (non-passive): the owner regularly loads cash, negotiates location contracts, performs maintenance, makes business decisions about machine placement. Must meet one of the 7 material participation tests under IRC 469. The easiest: 500+ hours/year OR substantially all participation.
Passive: the owner buys machines, hires a cash loading service, and has a management company handle everything. Losses are suspended under passive activity rules.
Why it matters: in early years, depreciation on 10-20 machines creates paper losses. If active, these losses offset W-2 or other active income. If passive, they’re suspended until the business is profitable or sold.

S-Corp break-even: $55,000-$65,000 in net profit

A 10-machine operation generates approximately $26,400/year in net profit (below break-even)
20+ machines ($52,800+/year) approach the break-even
25+ machines are needed before S-Corp clearly saves money
At 30 machines ($79,200 profit): S-Corp saves approximately $2,500/year

When does the S-Corp make sense for ATM operators?

Hypothetical example

Round numbers. An ATM operator with 25 machines. Single filer. Manages locations, loads cash personally for 15 machines, uses a loading service for 10.

Revenue:

25 machines x 200 transactions x $3.00 surcharge x 12 months = $180,000 gross
Location commissions (40% average): ($72,000)
Net revenue after commissions: $108,000

Expenses:

Category	Amount
Processing fees (25 x $35 x 12)	$10,500
Network/connectivity (25 x $30 x 12)	$9,000
Cash loading service (10 machines x $50 x 12)	$6,000
Vehicle (10,000 miles x $0.70)	$7,000
Insurance	$2,500
Maintenance and repair	$3,000
Phone	$600
Software (route management)	$500
Total expenses	$39,100

Net profit: $108,000 - $39,100 = $68,900

Option A: Sole Proprietor

SE tax: $68,900 x 92.35% x 15.3% = $9,732
SE deduction: ($4,866)
QBI: $68,900 x 20% = ($13,780)
Taxable: $68,900 - $4,866 - $13,780 - $15,000 = $35,254
Income tax: approximately $3,942
Total tax: $13,674

Option B: S-Corp ($40,000 salary)

FICA: $40,000 x 15.3% = $6,120
K-1: $28,900
QBI: $28,900 x 20% = ($5,780)
W-2 wage limit: 50% of $40,000 = $20,000 (exceeds $5,780)
Taxable: $68,900 - $5,780 - $15,000 = $48,120
Income tax: approximately $6,000
S-Corp costs: $2,200
Total: $14,320

At $68,900 profit, the sole proprietorship actually costs LESS by $646. The QBI deduction reduction from the lower K-1 offsets the SE tax savings.

At 40 machines ($110,000 profit):

Sole proprietor total: approximately $23,000
S-Corp ($45,000 salary) total: approximately $20,800
S-Corp saves: $2,200/year. Now it’s worth it.

Year 1 equipment depreciation:

Item	Cost	Year 1 Deduction
25 ATM machines ($3,500 each)	$87,500	$87,500
Installation (25 x $300)	$7,500	$7,500
Used van for cash loading	$15,000	$15,000
Safe for vault cash	$2,000	$2,000
Total	$112,000	$112,000

The $112,000 depreciation deduction far exceeds the $68,900 net operating profit. This creates a Year 1 loss of approximately $43,100, which offsets W-2 income from another job (if the owner materially participates, making it active). If passive, the loss is suspended.

The material participation question is the single most important tax planning issue for ATM businesses. The owner should track hours meticulously. Loading cash for 15 machines weekly takes approximately 1.5 hours per machine per week = 22.5 hours/week x 50 weeks = 1,125 hours. This easily meets the 500-hour material participation test.
