Pest control business owners have a strong retirement planning opportunity because the business is NOT an SSTB (it is a physical service trade), meaning the full 20% QBI deduction is available at any income level. When combined with retirement plan contributions, the effective tax rate for a pest control business owner can drop to 10-15%, even at $150,000+ income levels.

✓Key takeaway

Retirement plan options for pest control businesses:

Solo 401(k) (best for owner-only or owner + spouse):

Employee deferral: $24,500 (2026), plus $8,000 catch-up (age 50+), plus $11,250 super catch-up (ages 60-63)
Employer contribution: 25% of W-2 salary (S-Corp) or approximately 20% of net SE income (sole proprietor)
Combined max: $72,000 (2026)
Available only without other full-time employees (technicians must be part-time or contractors, which is unlikely for pest control, see worker classification)

SIMPLE IRA (best for small teams, 2-10 technicians):

Employee deferral: $16,500 (2026)
Employer match: dollar-for-dollar up to 3% of compensation, for all eligible employees
Lower contribution ceiling than Solo 401(k)
SECURE 2.0 credit: businesses with 50 or fewer employees can claim a tax credit equal to the employer matching contributions (phased in over 5 years)
Must be established by October 1

SEP IRA (simplest, but most expensive with employees):

Employer-only contributions: 25% of compensation for each eligible employee
If the owner contributes 25%, the same percentage must be contributed for ALL eligible employees
With 5 technicians earning $45,000 each: $45,000 x 25% x 5 = $56,250 in required employee contributions
This makes SEP expensive for pest control businesses with employees

For pest control businesses with technicians (employees): The Solo 401(k) is NOT available (technicians are employees, not contractors). The SIMPLE IRA is the best balance of contribution size, employer cost, and simplicity.

How do retirement contributions and QBI stack?

Hypothetical example

Round numbers. A pest control S-Corp owner has 4 technician employees. Revenue: $350,000. After wages, chemicals, vehicle costs, and other expenses: net income before owner salary = $160,000. Reasonable salary: $65,000.

Without retirement plan:

Owner salary: $65,000 (FICA: $9,945)
K-1 income: $95,000
QBI deduction: $95,000 x 20% = $19,000 (NOT SSTB)
Taxable income: $65,000 + $95,000 - $15,000 - $19,000 = $126,000
Income tax: approximately $20,500
Total tax: $30,445
Effective rate: 19.0%

With SIMPLE IRA:

Owner deferral: $16,500
Employer match for owner (3% of $65,000): $1,950
Employer match for 4 technicians (3% of $45,000 each): $5,400
Total employer match: $7,350 (deductible by S-Corp)
S-Corp income after employer match: $95,000 - $7,350 = $87,650
Owner W-2 reduced by deferral: $65,000 - $16,500 = $48,500 (for income tax purposes)
QBI on K-1: $87,650 x 20% = $17,530
Taxable income: $48,500 + $87,650 - $15,000 - $17,530 = $103,620
Income tax: approximately $16,400
Total tax: $26,345
Effective rate: 16.5%

Tax savings from SIMPLE IRA: $4,100/year Retirement savings built: $16,500 (owner) + $1,950 (match) = $18,450/year

SECURE 2.0 credit:

Employer matching contributions for first 5 years: $7,350/year
Credit: 100% for employers with 50 or fewer employees (year 1-2), phasing down
Year 1-2 credit: $7,350 (fully offsets employer match cost)
Net cost of the SIMPLE IRA to the business: $0 for the first 2 years (SECURE 2.0 credit covers it)

This means the retirement plan costs the business nothing in the early years while producing $4,100 in annual tax savings and building $18,450 in retirement savings for the owner.

How much can I contribute to each retirement plan type?

The Solo 401(k) generally allows the highest total contribution because it combines an employee deferral (the standard 401(k) limit, plus a catch-up amount for ages 50 and over) with an employer profit-sharing contribution of up to 20% of net self-employment income (the effective rate for a self-employed owner). A SEP IRA allows only the employer contribution (up to 20% of net SE income) with no employee deferral. A SIMPLE IRA has a lower employee deferral ceiling but simpler administration. At $100,000 net profit, a Solo 401(k) typically allows about $42,000 to $43,000 in total contributions (2025 and 2026 deferral limits, before any catch-up), while a SEP IRA caps around $18,600. Contribution limits adjust annually for inflation.

What changes if I hire employees beyond myself and my spouse?

Adding employees changes the plan math significantly. A SEP IRA requires the same contribution percentage for all eligible employees: contributing the effective 20% for yourself means contributing 25% of pay for every eligible employee. A SIMPLE IRA requires either a dollar-for-dollar match up to 3% of compensation or a flat 2% non-elective contribution for everyone. The Solo 401(k) is available only to owner-only businesses (the owner plus spouse); hiring even one common-law employee who meets eligibility thresholds converts it to a standard 401(k) with nondiscrimination testing and higher administration costs ($1,000-$3,000/year). Choose the right structure before your first hire.

How do specified service trades or businesses affect your QBI deduction?

Specified service trades or businesses (SSTBs) including law, medicine, accounting, consulting, financial services, and performing arts face a phase-out of the QBI deduction at higher income levels. For 2025, the QBI deduction phases out for SSTBs between $191,950 and $241,950 for single filers and $383,900 and $483,900 for joint filers, with zero deduction above the upper threshold. Non-SSTB businesses above the income threshold are limited to the greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property, but they never lose the deduction entirely. The SSTB classification looks at the principal asset of the business, so if more than 10% of gross receipts come from specified service activities (5% for businesses with over $25 million in gross receipts), the entire business is treated as an SSTB.
