Cash Balance Plans: The $250K Physician Tax Deduction
A $250,000 Deduction Most Physicians Never Hear About
A 55-year-old physician earning $600,000 can put away $32,500 in a 401(k) with catch-up contributions, plus some profit sharing, and call it a day. Add a cash balance plan to the same practice and the annual deductible contribution can jump by $150,000 to $250,000 or more. That gap is why actuaries and pension consultants keep getting calls from partners in orthopedic groups, anesthesia practices and radiology shops.
The timing matters. It is late October 2026, and a new defined benefit plan generally has to be adopted by December 31 to count for this tax year. Two months is tight but workable if the practice moves now, and it is far easier than discovering the idea in April.
Cash balance plans are not new. They came out of the 1980s as a hybrid that keeps the legal structure of a traditional pension but reports benefits as an account balance, which employees (and partners) find easier to follow. Banks were early adopters, and the Pension Protection Act of 2006 settled many of the legal doubts that had surrounded them.
For physicians the appeal is plain. Most of them start saving seriously in their mid-30s after residency, fellowship and loans, and they run into the ceiling on ordinary retirement accounts just as their income peaks. A cash balance plan raises that ceiling by an order of magnitude.
How the Plan Works Behind the Account Statement
A cash balance plan is a defined benefit plan. Each participant has a hypothetical account that grows from two sources: a pay credit (a set dollar amount or percentage of pay each year) and an interest credit (a fixed rate such as 4% or 5%, or one tied to a Treasury yield). The employer owns the investment risk and the investment decisions, and the plan promises the participant the balance.
This is different from a 401(k), where the participant's balance rises and falls with the market. Here the promised balance only grows by the formula. If the plan's actual investments earn more than the interest credit, the practice needs to contribute less later. If they earn less, the practice has to make up the shortfall.
The size of the allowed contribution comes from an annual benefit limit under Section 415. For 2026 that limit is about $290,000 per year of lifetime income, and the plan can fund the lump-sum value of that benefit. The closer a participant is to retirement, the fewer years remain to fund it, so the allowed contribution rises sharply with age.
As rough guides, a partner around 40 might contribute $90,000 to $120,000 a year, someone near 50 perhaps $170,000 to $230,000, and someone near 60 well above $250,000. These are ballpark figures that depend on plan design, pay history and current interest rates, and an actuary will give the real numbers. Pay credits also follow compensation, which the tax code caps for plan purposes (about $360,000 in 2026), so the design usually uses fixed dollar credits for owners.
A common misconception is that the plan replaces the 401(k). It does not. Most practices run both, so the partner defers $24,500 (plus catch-up if eligible) into the 401(k) and the cash balance plan sits on top. The tax code usually limits the deduction for a profit-sharing contribution to about 6% of eligible pay when both plans exist, which is a quirk worth planning around.
The Real Cost: Staff, Fees and a Three-Year Promise
Nobody gets this deduction without paying something. Nondiscrimination rules require the plan to treat non-owner employees fairly, so the practice typically gives staff a pay credit of around 5% to 7.5% of pay. A practice with $400,000 of covered staff payroll might spend $20,000 to $30,000 a year on those credits.
Set against a partner's contribution of $200,000 at a combined federal and state rate near 42%, which saves roughly $84,000 in tax, a $25,000 staff cost looks acceptable. The numbers get worse with a large staff, high turnover, or a small group of partners where few people share the staff cost. A solo practitioner with no employees has the easiest case. A two-partner practice with 30 employees has the hardest.
Administration adds more. We expect actuarial and third-party administrator fees in the range of $3,000 to $8,000 a year, plus per-participant premiums to the Pension Benefit Guaranty Corporation for most plans. The plan requires an annual actuarial certification, and the plan sponsor signs off on the funding.
Then there is the commitment. The IRS intends plans to be permanent and expects them to last, with a rule of thumb that we should plan on at least three to five years. A bad year of income does not cancel the funding obligation, because the actuary sets a minimum contribution each year. Some designs let the practice choose a range between minimum and maximum, which gives some room.
We think the practices that regret these plans are the ones that sized them to their best year. Sizing to a conservative year of income, then adding the rest through a flexible profit-sharing contribution, leaves more room if revenue dips. Terminating or freezing a plan is possible, but it costs time and money and sends a signal to staff.
Investing Money That Has a Fixed Target
Plan assets are pooled and invested by the practice (or an advisor it hires), but the target is the interest credit. If the credit is 4.5%, the plan wants to earn about 4.5% reliably, because earning 9% in one year and losing 15% in another produces unpleasant swings in required contributions. A volatile portfolio can force a practice to write a large check just after a market decline.
This is why most cash balance plans hold short-to-intermediate Treasuries, high-grade corporate bonds, CDs and stable-value-type holdings, and sometimes a small slice of equities. Nobody is excited about that allocation, but its job is to match a liability. Think of it as a savings vehicle with a tax deduction attached, not as the growth engine of a retirement plan.
That affects where other investments go. A physician who holds equity funds such as VEA, the Vanguard FTSE Developed Markets ETF, for international diversification belongs in a different bucket from the plan's bond ladder. VEA fits better in a taxable account, a Roth, or the 401(k) side, where the participant sets their own risk and has decades to ride out drawdowns.
The same logic applies to a concentrated position. Say a physician has accumulated shares of Citigroup (ticker C) through a prior employer plan or an old brokerage account, and it has grown to 15% of the household's investable assets. A bank stock carries credit-cycle and regulatory risk, and it sits in the same sector as many other holdings. The deduction from a new plan can soften the tax cost of trimming such a position, since gains realized in a year with a large offsetting deduction feel less painful. That is a planning idea, not a recommendation to buy or sell any particular security.
Two Physicians, Two Outcomes
Take Dr. A, a 52-year-old partner in a four-physician cardiology group, earning $650,000. The group has eight staff members with total covered pay of $480,000. An actuary designs a plan with a $190,000 annual credit for each partner and a 6% pay credit for staff, which costs $28,800.
The group's total contribution is $190,000 times four partners plus $28,800, or $788,800 per year. Dr. A's tax saving on a $190,000 deposit at a 37% federal rate plus 5% state is about $79,800. After three years, the account holds roughly $600,000 including a 4.5% interest credit, and at retirement it can be rolled into an IRA without tax.
Now take Dr. B, a 38-year-old solo hospitalist who is an independent contractor earning $380,000 with no staff and a young family. An actuary might allow a $70,000 to $90,000 annual contribution. Dr. B's income varies by 25% from year to year and the household has a mortgage and daycare costs.
Here the plan is workable but riskier. A modest design with a lower funding target, together with a larger emergency reserve, probably serves Dr. B better than the maximum. If income dropped sharply, a required contribution of $80,000 could crowd out other goals.
The first physician is nearly ideal. The second is a candidate who should choose carefully, and possibly wait a few years until income stabilizes and age increases the allowed amount.
Putting a Plan in Place Before December 31
Start with a conversation with a third-party administrator or an actuarial firm that works with medical practices. Most will run a free illustration if you supply ages, pay, and the staff census. Ask for at least two designs: a maximum one and a conservative one.
Then compare the staff cost against the tax savings for each partner. We can sometimes design a plan so that partners fall into different groups with different credits, as long as the testing works. All partners need to agree, since the plan covers the practice and affects distributions.
Pay attention to the interest credit. A fixed 5% credit is easy to explain but may be hard to earn from a bond portfolio when yields fall. A credit tied to a Treasury yield or to the actual return on plan assets (within limits) lowers the risk of a mismatch. Ask the actuary how each option changes contributions under a few interest-rate scenarios.
Coordinate with a tax advisor on the 401(k) and profit-sharing structure, because the combined deduction limits are easy to trip over. Check also whether the group files as a partnership, S corporation or C corporation, since that changes how the tax code measures owner pay. Missteps here can reduce or delay the deduction.
Finally, plan the exit. When a physician retires or leaves, they generally roll the balance into an IRA, which preserves tax deferral. The IRS taxes large lump sums taken as cash in full, so we should map the timing of retirement relative to other income years ahead.
What to Do With Two Months Left
A cash balance plan suits high-income physicians in their 40s and 50s who have stable income, few or manageable staff, and already max out their other retirement accounts. It suits them less when income swings widely, staff costs are high relative to partner contributions, or the household has no cash reserve. For those it can wait.
If it does fit, the sequence is short. Gather the census, ask an actuary for two illustrations, compare staff cost with partner tax savings, and talk to the other partners. Adopt the plan document before year-end, then fund it by the deadline the actuary gives, which is often the tax filing date.
Keep the plan's assets conservative and match them to the interest credit. Put growth assets such as VEA in accounts where we control the risk and the time horizon is long. If a legacy holding like C has grown into an outsized share of the household balance sheet, consider whether the deduction year is a good time to rebalance it.
The most useful first step this week is a call to an administrator, and the second is a candid look at the next three years of practice income. A plan that fits the cash flow can add a six-figure deduction every year, and a plan that does not fit becomes a burden. The difference comes down to sizing it properly and starting early enough to do it carefully.
