A solo consultant should test a defined benefit plan against uneven contracts, adjusted self-employed compensation, future hiring, and weak-year cash before requesting an actuarial proposal.
A solo consultant can consider a defined benefit plan, but one exceptional billing year is a poor basis for an ongoing promise. The useful first question is whether the consulting business can fund a professionally designed plan when contracts slip, not how large a headline deduction might be. The IRS describes a formula-based retirement benefit and an enrolled actuary's annual role in setting funding. This article builds a consultant-specific decision file; our business-owner checklist covers the broader go-or-pause questions.
List signed contracts, expected collections, renewal dates, receivables at risk, and planned subcontractor costs for the next 12 to 24 months. Then prepare a weaker-case forecast: one major client delays a renewal, or a new project starts three months late. A plan illustration based only on the strongest year's invoices misses the central consulting risk. Use the same reconciled books and cash assumptions that support a useful monthly close review.
For an illustrative screening exercise, assume a consultant billed $300,000 in Year 1, with $90,000 of operating costs and $55,000 reserved for taxes, working capital, and slow collections. That leaves $155,000 of illustrative cash capacity before owner living needs and any retirement-plan funding. Year 2 has only $180,000 under contract, $75,000 of expected costs, and the same $55,000 protected reserve: $50,000 remains before owner living needs. These figures are cash-screening assumptions, not plan compensation, a permissible contribution, or a tax deduction. If a proposed actuarial funding range cannot fit the weaker year and owner cash needs, ask about a different design or timing before committing.
A solo consultant may invoice as a sole proprietor, partner, or through a corporation. Bring the entity documents, prior return, current profit-and-loss statement, owner payroll or draw records, and existing retirement-plan documents to the tax adviser and actuary. For a self-employed person, the IRS explains that plan compensation is not simply Schedule C profit; adjustments apply. A distribution, gross invoice, and W-2 wage are not interchangeable inputs. Do not accept a plan quote that combines them without identifying the sponsor and governing calculation.
Ask the actuary to state the assumed retirement benefit, compensation definition, funding range, investment assumptions, and what would prompt a new valuation. The IRS notes that the employer's required contribution normally fluctuates from year to year. No article can infer your allowable amount from revenue alone.
“Solo” is a present fact, not necessarily a permanent plan feature. Make a hiring timeline for employees, a spouse on payroll, partners, and related businesses. Record expected hours and dates of service. The IRS's general eligibility discussion describes age and service rules, but the actual plan terms and related-employer facts control. Ask the plan professional to model the effect of a likely hire before signing a proposal.
Write down who supplies payroll and census changes, who performs the valuation, who monitors minimum funding, who files the applicable annual return, and who reviews fees. The IRS's general plan overview discusses annual Form 5500 reporting and actuarial schedules. Under owner-only Form 5500-EZ rules, a one-participant plan may be exempt from annual filing while combined assets of the employer's one-participant plans are $250,000 or less, but a final-year return is still required. Have the administrator determine the right form and deadline for the actual plan rather than relying on a generic article. The Department of Labor's employer guide explains oversight duties where applicable.
