A center bought in 2005 for $2.0 million and worth $5.5 million carries a $1.27 million tax bill. That bill is an interest-free loan, and the walk-away yield tells you whether it is still worth keeping.
The tax you would owe on selling a center you have owned for twenty years is not a penalty waiting at the exit. It is a loan. The IRS has been lending it to you, interest free, for as long as you have been taking depreciation, and the only real question is whether your building earns enough on your own money to keep borrowing it.
Most long-time owners treat the tax as a veto. The number is large, it feels like a punishment for selling, and so the center stays unsold by default. That is the wrong way to use it. A loan you never priced is not a strategy.
This is not tax or legal advice. Run your own numbers past a CPA before you act on any of it.
You have been borrowing from the IRS since 2005
Every year you owned the building you took depreciation, and every dollar of it lowered your basis. The deduction was real. So is the bill that comes back at the sale. In between, the money stayed in your building, working for you.
Take a 24,000 square foot neighborhood center bought in 2005 for $2.0 million, $400,000 of it allocated to land. The $1.6 million building has been depreciated straight line over 39 years. Twenty-one years of that is about $862,000, and the adjusted basis is now about $1.14 million. The center is worth $5.5 million. Sell it with 3% in costs and the taxable gain is about $4.20 million.
That gain is taxed in four layers. Assume a married couple filing jointly with income above every threshold, no improvements added to basis, no mortgage and no federal deduction for the state tax.
- Recapture. The part of the gain equal to the depreciation you took, unrecaptured Section 1250 gain, is taxed federally at up to 25% (IRS Topic 409). This is the depreciation recapture people talk about: $862,000 at 25% is $215,000.
- Capital gain. The rest, $3.34 million, is taxed at 20%. For 2026 that rate starts above $613,700 of taxable income on a joint return. $667,000.
- Net investment income tax. 3.8% on the whole gain for a passive owner with income above $250,000 on a joint return. $159,000.
- Wisconsin. The state deducts 30% of a long-term gain and taxes the rest at up to 7.65%. The 2025 to 2027 budget process considered taking that exclusion away from high earners, and the Legislature dropped it. $225,000.
Total: about $1.27 million. That is 30% of the gain and 23% of the price. Sell today and you walk away with about $4.07 million.
Notice the orange bar. It is tax on deductions you already enjoyed, at a rate above the capital gain rate. It is the interest you never paid on the loan, showing up all at once.
The only yield that matters is the walk-away yield
Ask a long-time owner what the center earns and you will usually hear a return on cost. At a 7.5% cap rate this center produces about $412,500 of NOI. On the 2005 price that is 20.6%, and it is a comforting number. It is also meaningless. The $2.0 million left the building a long time ago.
The number that decides whether to hold is what we call the walk-away yield: NOI divided by the after-tax cash you would actually have if you sold today. Here that is $412,500 on $4.07 million, or 10.1%.
That is the honest price of holding. Keep the center and you are earning 10.1% on your own money, because the IRS's $1.27 million is still in the building working for you at no charge. Sell, and your $4.07 million has to find 10.1% somewhere else, with the same risk and the same amount of your time, to break even.
Now look at the third bar. A twenty year old center rarely gets to spend its NOI. Put $100,000 a year of roof and parking lot against it and the walk-away yield drops to 7.7%, barely above what a buyer earns on the full $5.5 million price. At that point the free loan is not doing much for you. You are carrying the building's capital needs and your own time for a return a stranger could get by buying it from you.
If you carry a mortgage, run it on the cash: NOI less debt service, divided by after-tax proceeds less the payoff.
Nobody earns a fee when you do nothing
Once an owner starts thinking about selling, the advice arrives from people who are paid when something happens. The broker is paid when you sell. The exchange intermediary is paid when you exchange. The sponsor of a Delaware statutory trust is paid when you buy into it, and again every year you stay. None of this makes the advice wrong. It does mean that nobody at the table is paid when the right answer is to do nothing.
The 1031 exchange is a good example. It rolls the whole loan forward into a new property, which is valuable. But it runs on a clock: you must identify replacement property in writing within 45 days of closing and close on it by the earlier of 180 days or your return's due date (Form 8824 instructions). Any cash you keep, and any debt you shed without replacing, is boot, and boot is taxable. An owner who must buy something in six weeks is the most motivated buyer in the market, and motivated buyers overpay. Deferring $1.27 million by overpaying $500,000 for the replacement is a worse trade than it looks: the overpayment is permanent, and the tax is only postponed.
A Delaware statutory trust solves the clock and the management, and it counts as replacement real estate (Rev. Rul. 2004-86). The price is control. To keep the tax treatment the trustee cannot renegotiate leases, sign new ones, raise capital or refinance. You are giving up the exact skills that built your gain, you usually cannot get out until the sponsor sells, and the sponsor's fees come off the top of your return every year.
Every option repays the loan, rolls it forward or forgives it
Seen as a loan, the options sort themselves.
Repay it all. An outright sale. You pay $1.27 million and you are done with tenants, roofs and reconciliations. If your walk-away yield after capital is close to what a buyer earns, this is often the right answer, and the tax is simply the cost of getting your time back.
Roll it over. A 1031 or a DST. The loan follows you to the next property with your old basis. Worth doing when you can buy something you would want anyway, not something you need by day 45.
Repay it on a schedule. An installment sale. With 20% down, the down payment alone recognizes about $839,000 of gain and about $287,000 of tax in the year of sale. Two catches: recapture taxed as ordinary income, usually from cost segregation or bonus depreciation, is due in the year of sale no matter what you collect (IRS Publication 537), and the 25% layer comes out of the payments first. You also become your buyer's lender, and if the buyer stops paying, you get the center back.
Repay a slice. Sell a 40% tenant in common interest or a share of your LLC. At a proportional price it raises about $2.13 million after costs and owes about $507,000. Expect a buyer of a minority interest to ask for a discount, and write the operating agreement before you need it.
Or let it be forgiven. Heirs receive the property with a basis stepped up to its value at death, and the loan is never repaid. For 2026 the federal estate tax exclusion is $15 million per person, and Wisconsin has had no estate tax since 2008. This is the only option that makes the $1.27 million disappear rather than move it, and it works on exchange property too. The cost is that you keep owning, and holding only beats selling if the building is easy to own. That is a management problem as much as a tax one, and professional management is often what makes it work.
An afternoon with your file
Do this before anyone with a commission is in the room.
- Find the closing statement and depreciation schedule. Note the land allocation, every improvement and any cost segregation study.
- Work out adjusted basis: price, plus improvements, minus all depreciation taken.
- Estimate the tax at a realistic price: 25% on the depreciation, 20% on the rest, 3.8% on the whole gain, about 5.4% for Wisconsin.
- Subtract it, and any mortgage payoff, from the net price. That is your walk-away cash.
- Divide NOI, less a realistic yearly capital budget and any debt service, by the walk-away cash. That is your walk-away yield.
- Compare it with what you would actually do with the money, and with what your time is worth.
- Take the numbers to your CPA and estate attorney together, before you list.
If the walk-away yield is strong and the building is easy to own, keep borrowing. If it is thin, the tax bill was never the reason to stay.
