Year-End Tax Strategies for Dentists in New York: Equipment Purchases & Deductions
August 12, 2026
The final months of the calendar year are when the gap between a reactive tax approach and a planned one becomes most expensive. For dental practice owners in New York, the decisions made between October and December carry real consequences: how much income is deferred, which equipment is placed in service, how compensation is structured, and whether the practice is positioned heading into the new year in a way that reflects deliberate choices rather than defaults. None of those decisions can be made well in a vacuum, and very few can be corrected once December 31 passes.
The pressure is sharper in New York than in most other markets. State and city tax obligations layer on top of federal liability in ways that make proactive planning significantly more valuable here than elsewhere. LLI Advisory Group has worked with dental practice owners across New York for over 20 years, and our dental tax and accounting services are built around year-round engagement, so the fourth quarter becomes a confirmation of a strategy rather than the moment one gets assembled.
Why Equipment Timing Is a Tax Decision, Not Just an Operational One
A dental practice that needs a new cone beam CT unit, a digital impression system, or updated operatory chairs has a legitimate operational reason to make that purchase. What many practice owners do not fully weigh is that when the purchase happens within the year is a tax decision as meaningful as the price negotiated with the vendor.
According to the IRS Instructions for Form 4562, qualifying business property placed in service during a tax year may be eligible for immediate expensing under Section 179, with a deduction limit of $2,500,000 for tax years beginning in 2025. Equipment purchased and placed in service before December 31 creates a deduction for that tax year. Equipment that arrives on January 2 does not. That single calendar distinction can shift a six-figure deduction across tax years, and whether that shift is beneficial depends entirely on what the income picture looks like on each side of it.
The Income Context Changes Everything
This is where the conversation becomes more nuanced than a straightforward “buy equipment to save taxes” framing. An equipment deduction reduces taxable income, but the value of that reduction depends on what marginal rate the income would otherwise be taxed at. A New York dental practice owner finishing a strong production year with healthy net income has a compelling case for accelerating an equipment purchase. A practice whose income is unusually compressed due to a staffing gap, a temporary closure, or early-stage growth may find less value in the same move.
We look at each client’s projected income well before recommending year-end purchases as a tax strategy. By October or November, we should already know where the year is heading and have the time to act deliberately. The practices that benefit most from year-end equipment planning are the ones where that conversation starts early enough to actually shape the outcome. When a client calls us in the final week of December with a purchase question, we can still help, but we are working with fewer options than we would have had six weeks prior.
Fee Structure as a Year-End Consideration
One conversation we have with New York clients at year-end that often produces more immediate results than equipment planning involves their fee schedule. We provide our clients with annual surveys that show where their fees should be relative to other practices in their specific zip code. What we consistently find is that practices that have not revisited their fees in two or three years are leaving meaningful revenue on the table, and that pattern gets compounded by any inflationary pressure on supplies, lab costs, and staffing.
A fee adjustment that takes effect at the start of a new year changes the income trajectory going forward in a way that affects every subsequent tax planning conversation. We build that into our year-end reviews as part of the broader picture rather than treating it as a separate administrative item.
The Interplay Between Equipment Purchases and Other Year-End Moves
The equipment purchase decision does not exist on its own. It is one variable in a year-end review that also includes:
Retirement Contribution Sequencing
Retirement contributions reduce taxable income and should be evaluated before committing capital to equipment. For high-income New York dentists, the question is often which lever moves more income out of the highest bracket at the lowest cost. A defined benefit plan contribution, for a practice owner who has one in place, can dwarf what an equipment deduction produces in tax savings for that year. Getting the sequencing right between retirement funding and equipment investment requires a current income projection, not a heuristic.
Bonus Depreciation and New York State Conformity
New York does not always conform to federal bonus depreciation rules, which means the deduction a practice owner takes at the federal level may not flow through identically at the state level. For New York City practitioners, the city tax adds another layer to that analysis. Understanding exactly how much of an equipment deduction the practice will realize at each level of taxation is something we work through with clients specifically, because the answer in New York frequently differs from the headline federal number.
Compensation and Distribution Review
How owner compensation is structured heading into year-end affects both the practice’s payroll obligations and the owner’s personal tax position. Practices structured as S corporations have a specific set of considerations around salary versus distribution that require an updated look before the year closes. We approach this as part of the same year-end review rather than a standalone item, because the decisions interact with each other in ways that matter.
The Habits That Make Year-End Planning Actually Work
Gerard Iacovano, CPA, has described the difference between compliance services and advisory services this way: compliance is what you have to have, and advisory is what you want to have. Year-end tax planning at its best is a product of the advisory relationship built across the entire year. For newer practice owners especially, establishing those habits early changes the quality of every subsequent year-end conversation. Our dental practice startup services build this structure from the beginning, because a practice owner who has been reviewing their financial position quarterly since year one arrives at year-end with a current, accurate picture rather than a catch-up exercise.
For practice owners approaching a transition, year-end equipment decisions carry an additional layer worth examining. How recently purchased equipment is depreciated affects the balance sheet, which shapes how a practice valuation is constructed. That is not a reason to avoid purchases, but it is a reason to have the conversation before the purchase rather than after.
LLI Advisory Group Handles Year-End Tax Planning for New York Dentists
LLI Advisory Group has spent over two decades working year-round with dental practice owners across New York on integrated tax planning that turns the fourth quarter into a managed close rather than an emergency. Gerard Iacovano, CPA, and Domenick Lobifaro, CPA, MST, lead a team that has sat across from clients at every income level, every practice stage, and every variation of the New York tax environment. We hold to a 24-hour response commitment because the questions that come up in October and November are often the ones that determine how December ends, and our clients should never be waiting days for an answer when the calendar is moving.
