What happens when your CPA and advisor talk

The setup is common. You have an accountant who does your taxes and a financial advisor who manages your investments. They are both good at what they do. They have never been in the same room, or on the same call, or in the same email thread. The result is that each one is working from an incomplete picture of your household.

The CPA doesn't know what's happening in the portfolio — which accounts hold which assets, what the unrealized gain situation looks like, what distributions are expected this year. The advisor doesn't know what deductions are being taken, what the effective rate was last year, or whether there's a passive loss that could absorb some income. Both are doing their jobs correctly. The coordination layer doesn't exist.

When that coordination does exist — when we sit down with your CPA before the year happens, not after — the decisions get better. The Roth conversion that makes sense in isolation looks different if you know the CPA is bunching charitable deductions this year. The tax-loss harvest that feels optional becomes obvious if you know what other income is coming. The order of operations matters, and neither advisor can see the whole order alone.

There's a practical question about how this works. Some clients have CPAs they've worked with for years and have no interest in switching. We work alongside them — we provide the portfolio data, the expected distributions, the conversion modeling, and they do the return. Other clients don't have a CPA they trust. We have a short list of independent CPAs in the area we refer to, not because they pay us (they don't), but because we've seen how they work.

The year we most often see clients wish they'd started earlier is the year before retirement. That's when the tax math becomes genuinely complex — the last year of W-2 income, the first RMD calculation, the window for conversions before Social Security layers in. That year is much harder to navigate when the CPA and the advisor are still strangers.

There's a subtler benefit to the coordination that goes beyond pure tax savings. When two advisors are looking at the same household simultaneously, they catch things the other misses. A CPA who sees a client's Schedule K-1 from a small partnership might notice a passive activity loss that's been accumulating for three years — and flag it to us, so we can model a year in which we realize enough capital gains to absorb it efficiently. We might notice that a client's taxable account holds a significant position in a low-basis stock that's also held in a fund inside the IRA, creating unintentional concentration that the CPA had no way of seeing. Neither advisor has the full picture alone. The overlap is where most of the value gets created.

The practical implication for clients who want to make this work: schedule a call in October or November, before year-end decisions are irreversible. Bring us and your CPA together for forty-five minutes. The agenda is short — what's the year looking like from a tax standpoint, are there any trades or conversions worth doing before December 31st, and is there anything we should coordinate on before the return is filed. That one call tends to be worth more than the prior twelve months of parallel but disconnected advice.

For new clients, the first CPA coordination call usually happens in the onboarding year, and the discoveries are often significant. A CPA who has been preparing the return in isolation may have been sitting on information — a passive loss carryforward, a basis tracking issue, a missed deduction — that changes how we manage the portfolio going forward. We have seen clients leave the first three-way call with a clear action list worth tens of thousands of dollars in present-value terms, items that had been sitting untouched simply because nobody had arranged to be in the same conversation before.

The coordination is not a one-time event. It is a rhythm. Once a year before the return is filed, once a quarter in years with significant income events, more often when something changes. The clients who build this rhythm tend to have the most coherent financial pictures over time — not because they have more money, but because the left hand knows what the right hand is doing.

There is a category of tax decision that cannot be made correctly without both advisors in the conversation: the question of whether to accelerate income in the current year or defer it into the next. An investment account with significant unrealized gains, a potential Roth conversion, a year-end bonus, and a planned retirement-account distribution can interact in ways that push the household into an entirely different tax bracket depending on the sequencing. Neither the CPA alone nor the adviser alone has all the inputs. The joint conversation is where the answer lives — and where the savings, when they materialize, tend to be larger than either party expected going in. We have found that the clients most resistant to a three-way call are often the ones who benefit most from it once it happens. The resistance, when it exists, almost always comes from an assumption that the call will be complicated or time-consuming. It rarely is. Forty-five minutes, once a year, is usually enough to change the outcome of several decisions that would otherwise be made in isolation.
