The worst possible year to pay your tax lawyer: Why are my tax fees worth nothing the year I sell?

You would think the year the money finally arrives is the year the deductions matter most.

It's the year you can afford good advice, and the year you need it. The lawyers price the exclusion on your shares. The accountants work out which state can reach the proceeds. Somebody charges you real money to answer a question worth a great deal more than the fee.

In New York, that is the one year none of it is deductible.

Not reduced. Not phased down. The state has a rule that switches off, at a single income threshold, nearly every deduction you have, and the only year you'll ever cross that threshold is the year you sell.

Wait, these fees are deductible?

On a state return, yes, and this is the part most people have stopped expecting.

Fees you pay for tax advice, tax preparation, or investment management used to sit in a Schedule A category called miscellaneous itemized deductions. The 2017 tax law suspended it and the 2025 law made that permanent, so federally they're gone for good.

New York and California never conformed. Both still have the lines on their forms, running the old rules. (The letter before this one works out who can actually use them, and it is fewer people than you would think.)

Two conditions come attached, and both of them matter enormously in a year with a sale in it.

• A floor. Only the part of the category above 2% of your income is deductible, so the bar moves with what you earn.
• A ceiling. New York trims your itemized deductions once your income passes $100,000, and then does something far more aggressive higher up.

What does that cost in an exit year?

Let's follow Sohan, who spent six years building an edtech startup out of a sublet in Manhattan, through the year a larger company buys it.

For most of those years he paid himself $135,000 and took the standard deduction without thinking about it. Then the acquisition closes, and two things happen at once: his New York income lands at $1.6M, and the professional fees on his personal side come to $38,000. The opinion on whether his shares qualify for the small-business exclusion. The allocation question about which state gets the gain. A personal return that now runs to forty pages.

Here's what New York does with that $38,000. Two rules, and between them they take all of it.

The floor eats almost all of it. The floor is 2% of income, and 2% of $1.6M is $32,000. Only $6,000 of his fees was ever going to clear it. The same floor that cost him $2,700 four years ago costs him $32,000 now, because it grows with the very income that let him afford the lawyers.

Then the ceiling takes the rest. Under $1M, New York still allows a reduced version of your deductions. Once you pass $1M, that reduced version disappears too, and the state allows one thing only: half of what you gave to charity. Not a trimmed total. That specifically, and nothing else.

Every hour his tax counsel billed, on the most consequential tax question of his life, is worth zero on the return it was about.

Would paying them earlier have helped?

Enormously, and this is the whole lever.

Run the same $38,000 through the year before, when his income was $135,000. The floor is $2,700 instead of $32,000, so nearly all of it survives. New York's trim takes its slice. The standard deduction — $8,000 for a single filer — absorbs the first chunk. What's left is worth about $2,200 of state and city tax.

Same invoices. Same lawyers. Same advice. One tax year apart, and about $2,200 of difference.

Here's the honest limit on it. The work splits into two piles, and only one is movable:

• The planning work can usually be pulled forward. Whether the shares qualify, when the clock started, what the basis is, which state can reach the gain. That gets answered before a deal, often a year or more before, and a bill dated December instead of March lands in a year where it's worth something.
• The closing work can't. It happens when it happens, and no amount of calendar management moves it.

So the move isn't to pay everything early. It's to get the planning questions answered and invoiced in an ordinary year, which is also when the answers are more useful. And remember that the invoice date picks the tax year, not the work it covers. A bill that shows up in April for last year's planning belongs to the April it arrived in.

Does California do the same thing?

No, and the difference is worth a lot if you're choosing where to be.

California limits itemized deductions above a high income threshold too, but its limit is a percentage with a stop on it: the state can never take more than 80% of your itemized deductions. A fifth of them always survives, even at eight figures.

New York's rule isn't a percentage. It's a switch. Cross $1M and everything except half your charitable giving is simply off.

When is the deduction actually worth something?

The year you were already itemizing, which usually means the year you bought something.

Put a mortgage on the return and the standard deduction stops being an obstacle, because the interest cleared it before the fees showed up. Every dollar of professional fees then lands on top, at the full rate, instead of replacing a deduction the state was handing out for free. A large charitable year does the same thing.

Which is the useful way to think about this category: it pays best when it isn't doing the heavy lifting. It's a passenger, not a driver. In a year where something bigger already got you over the bar, the fees ride along and every one of them counts. In a year where they're all you've got, most of them disappear into the floor and the free deduction underneath.

What's your next move?

Ask what year the invoice will be dated, not what year the work is for. It's the only variable on the bill you control, and in the run-up to a sale it's the one that decides whether a five-figure fee is deductible or decorative.

Get the planning questions answered before the deal, not during it. Better answers, and they arrive in a year that can use the deduction. The qualification question in particular wants years of lead time, not weeks.

Most tax planning advice assumes deductions are worth more when your income is higher, because that's how brackets work. This category runs the other way. Its floor rises with your income and its ceiling drops on you entirely at the top, so its value peaks in the ordinary years and goes to nothing in the exceptional one.

The year you can finally afford the best advice of your life is the year New York decides it wasn't an expense at all. Pay for it early.

Quick refresher

• Miscellaneous itemized deductions. Tax advice, tax preparation, investment management fees, unreimbursed work expenses. Gone federally since 2017 and permanently since 2025, still allowed by New York and California.
• The 2% floor. Only the part of that category above 2% of your income counts, so the floor rises with the income that pays the fees.
• New York's $1M switch. Above $1M of New York income the state allows no itemized deduction except half of your charitable giving.
• California's 80% cap. California's limit on itemized deductions stops at 80%, so a fifth survives at any income.
