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: $23,500 (2025), plus $7,500 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: $70,000 (2025)
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 (2025)
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.
