Paying a seller for the rest of their life
The lifetime annuity as a purchase price: how it is structured, why an owner with no successor often prefers it, and the tax election that decides everything.
A seller with no successor and no need for a lump sum often wants something a buyer can supply more cheaply than cash: a payment that arrives every month for the rest of their life. Structured properly it is a genuine instrument with its own body of law and its own tax treatment, not a creative payment plan, and in the German-speaking market it has a name and a statute behind it.
What it actually is
A life annuity as a purchase price means the buyer takes the business and, in exchange, pays the seller a fixed recurring amount until the seller dies. Under German law the instrument is defined in section 759 of the civil code: a right granted for the duration of a person's life, producing continuous, equal, recurring payments in money or fungible goods.
The definition matters more than it looks. Equal and continuous payments for the duration of a life is a different legal animal from instalments over a fixed term, and the difference runs through everything downstream, particularly the tax. An arrangement that pays out over ten years regardless of whether the seller lives is not this instrument, whatever it is called in the contract.
That symmetry is why the structure holds up rather than being a trick. Neither side is obviously advantaged, both are exposed to the same variable, and the price is set by pricing that variable honestly. Any version where only one side carries the risk is a different deal wearing this one's clothing.
Why a seller would want this
The instinctive reaction is that no sensible person takes payments over cash. That reaction assumes a seller whose objective is to maximise a number, and a large share of the owners in this position have a different objective.
They do not want a lump sum
An owner in their late sixties with no successor is not looking for capital to deploy. They are looking for income that does not stop, and a large sum arriving at once is a management problem they did not ask for.
It removes the outliving problem
A fixed sum has to be made to last an unknown number of years. A payment for life does not. That transfer of longevity risk to the buyer is worth real money to somebody weighing it honestly.
The tax outcome can be better
Depending on the election taken and the seller's circumstances, spreading receipt across many years can land in lower brackets than a single large gain in one year. This varies enormously by situation and is the part that needs an actual advisor.
The business stays intact
Sellers who spent thirty years building something frequently care what happens to the name, the staff and the customers. A buyer who intends to keep operating it is a different proposition from one planning to merge it into something else, and the annuity signals a long horizon because it requires one.
The fourth reason is the one buyers underestimate. It is not sentimentality, it is that a seller taking payments for life has a direct, ongoing, personal interest in the business surviving. They will only accept this from somebody they believe will still be running it in fifteen years, which makes the structure a filter as much as a price.
A seller who will accept payment for life has told you something no diligence process can: they think you will still be there.
The tax election that decides everything
This is where the structure stops being a payment plan and becomes a genuine piece of planning, and it is almost entirely absent from English-language material on acquisitions.
When a German business, part-business or partnership interest is sold against risk-bearing recurring payments, the seller has an election. They can take immediate taxation, where the gain is calculated as the present value of the annuity less disposal costs less the tax book value at the moment of sale, and that gain qualifies for the allowance and the preferential rate available on a business disposal. Or they can take taxation on receipt, where each payment is taxed as subsequent business income in the year it arrives.
The two roads
Immediate: tax now, on the present value, at the preferential disposal rate with the allowance. Certain, done, and payable before most of the money has arrived. On receipt: nothing now, each payment taxed as it comes. No preferential rate, but the liability arrives alongside the cash and spreads across many years.
Separately, the income portion of an annuity, the part treated as return rather than capital, is determined by a statutory table keyed to the recipient's age when payments begin, and is taxed as other income. Which of these regimes applies, and which election is better, depends on the seller's age, their other income, the size of the gain and the term involved. It is genuinely case-specific and it is the single largest variable in what the seller actually keeps.
What has to be in it, from both sides
The structure is only sound if the protections are real, and they run in both directions. A buyer offering this without the seller's protections is asking for trust that has not been earned. A seller accepting it without the buyer's protections is creating a liability that can outlive the business.
- Security over something real, so the seller is not an unsecured creditor of a company they no longer control
- A minimum guaranteed period, so that an early death does not leave a spouse or estate with nothing after a business has changed hands
- Indexation, or an explicit decision not to index, because thirty years of inflation on a fixed nominal payment is a large silent transfer
- A set-off mechanism, so that warranty claims can be netted against future payments rather than pursued separately against a retired individual
- A present value stated in the contract at a defensible discount rate, because that figure drives the tax treatment and both sides need to agree it
- Clarity on what happens if the business fails, which is the conversation everybody avoids and the one that determines whether this is fair
The fifth item is the one both sides tend to wave through, and it deserves a number rather than a nod, because the gap between what the buyer promises and what it is worth is the whole reason the structure functions. Take 60,000 a year:
| Term | Nominal total promised | Worth today at 4% | Worth today at 6% |
|---|---|---|---|
| 10 years | 600,000 | 486,700 | 441,600 |
| 15 years | 900,000 | 667,100 | 582,700 |
| 20 years | 1,200,000 | 815,400 | 688,200 |
| 25 years | 1,500,000 | 937,300 | 767,000 |
Read the twenty-year row. The buyer commits to handing over 1.2 million and is transferring something closer to 700 or 800 thousand of value. Neither party is being deceived by that, it is simply what time does to money, and it is precisely why a seller can be offered a headline number well above what a cash buyer would pay while the buyer still clears their own arithmetic. Both of those sentences are true at once, which is unusual and is the reason this structure exists at all.
It also explains why the discount rate belongs in the contract rather than in somebody's spreadsheet. Move it from four to six percent on the twenty-year row and the present value drops by roughly 127,000. That is not a rounding difference, it is a negotiated term that happens to look like a technical input, and it drives the tax treatment as well.
Indexation is the row that decides who really pays
The third item in the list above is the same arithmetic pointed at the seller, and it is larger than it looks. A fixed nominal payment does not hold its value:
| Years in | What 60,000 is worth in today's money, at 2% inflation |
|---|---|
| 10 | 49,200, or 82% of it |
| 20 | 40,400, or 67% |
| 30 | 33,100, or 55% |
Thirty years in, an unindexed annuity is paying the seller a little over half of what they agreed to, in the only terms that matter to somebody buying groceries with it. At two percent. Anything higher and it is worse.
So indexation is not a nicety and it is not free either: it is a real transfer, and the honest thing is to decide it explicitly and price it, rather than let silence hand the whole of it to the buyer. A seller who does not raise this has usually not done the arithmetic. A buyer who notices that and stays quiet has.
Set-off is the buyer protection that matters most and is most often missing. Warranty claims against a seller who has been paid in full are frequently uncollectable in practice, because the money has been spent or moved. Against a stream of future payments they are simply netted, which is why this structure gives a buyer better recourse than a cash deal does, not worse.
The second is the seller protection that matters most. Without a guaranteed minimum period, an annuity is a bet the seller can lose completely in the first year, and no reasonable person should sign that. It also costs the buyer relatively little to provide, which makes refusing it a bad trade as well as a bad look.
How to price it without pretending to be an actuary
The temptation is to treat this as a life expectancy calculation. It is, partly, and that is the part where you should use published tables rather than judgement. The part that decides whether the deal works is different.
The binding test is coverage: whether the cash the business genuinely produces, averaged across several years rather than taken from the best one, can carry the annual payment with room left over. If it cannot, the structure has converted a purchase into an obligation the business cannot service, and the fact that the payments are spread out does not make that better. It makes it slower and harder to see.
Which is the same discipline as any other financed purchase, applied to a different instrument. The price still has to be set from rebuilt earnings rather than a headline figure, and the rebuilding is its own exercise. Where an annuity differs from a bank facility is that the counterparty is a person who cared about this company, which changes the negotiation and does not change the arithmetic.
One structural note that is easy to miss: this arrangement makes the most sense where the buyer genuinely intends to hold rather than resell. An owner planning an exit in five years is committing a future buyer to a payment stream attached to somebody they never met, which is a real complication in a later sale. For a permanent holder it is not a complication at all, which is one of the quieter advantages of having no fund clock. What I will and will not do on structure is on the buy page, and if you are the one considering this from the other side, it is worth raising early.
The short version
- The gap is the mechanism: 60,000 a year for twenty years is 1.2 million promised and roughly 700 to 800 thousand of value transferred. That is how a seller can be offered more than a cash buyer would pay while the buyer still clears their own arithmetic.
- The discount rate is a negotiated term wearing a technical costume. Four percent to six on a twenty-year annuity moves the present value by about 127,000, and it drives the tax treatment too.
- An unindexed payment pays about 55 percent of its real value by year thirty, at only 2 percent inflation. Decide indexation explicitly and price it, or silence hands the whole transfer to the buyer.
- A life annuity as purchase price is defined in German law as equal recurring payments for the duration of a person's life, which is legally distinct from instalments over a fixed term.
- Sellers take it because they want income rather than capital, because it removes the risk of outliving a lump sum, and because it signals a buyer who intends to still be there.
- German sellers have an election: immediate taxation on the present value at the preferential disposal rate, or taxation as each payment is received. It is the largest single variable in what they keep.
- Non-negotiable protections: security, a guaranteed minimum period, an indexation decision, a set-off right, an agreed present value, and a written answer for what happens if the business fails.
- Price it on whether multi-year average cash can carry the payment with room. Spreading an obligation the business cannot service does not fix it.
Questions I get on this
Can you buy a business by paying the owner a pension for life?
How is a business sold for a life annuity taxed in Germany?
What protects the seller if the business fails?
The instrument is defined in § 759 BGB. The seller's election between immediate taxation and taxation on receipt, and the statutory table determining the taxable income portion of an annuity, sit in German income tax law at § 22 EStG and the associated case law on disposals against recurring payments. This is a description, not tax or legal advice; the election in particular turns entirely on individual circumstances and needs a qualified advisor.
