Betterment tax (mas shevach): what to understand before selling a home

Second drawer from the bottom, in the kitchen. A purchase contract folded in half, one invoice from the bathroom renovation, a receipt for the solar water heater, and a bag of screws nobody can place. Half of the renovation receipts are in there. The rest might be in an inbox, on your partner's phone, or lost in the last move.

Then one night, after a chat with an estate agent or after hearing the neighbours sold, you type "betterment tax exemption" into your phone. Dozens of results come back, half of them written for lawyers, and you are left with a feeling: this is a tangled world only specialists understand.

Plenty of home owners meet the words mas shevach for the first time when they are already thinking about selling. That is exactly when it turns out part of the answer depends on papers from ten years ago.

Why betterment tax feels like a sale-day problem

Part of you says something entirely reasonable: "We're not even selling. Why open a tax question now? When the day comes, we'll deal with it." There is real sense in that. Tax feels threatening, and there is no point worrying about a sale that may never happen. Putting it off buys you quiet.

Another part of you, quieter, wants to know that when the day does come, the conversation with the lawyer will be short and calm, and nobody will have to rebuild a renovation from memory.

Each wants something worth having. What reconciles them is not learning tax law. It is one small habit.

Two familiar shortcuts trip people here. One is assuming "one home means no tax" without checking. The other is throwing receipts away, because who keeps those?

If you assumed, or threw things away, that is not on you. The law is complex and it changes, and nobody tells a buyer on signing day what to keep for the next ten or twenty years. The purchase lawyer is busy with the purchase, the bank with the mortgage. The sale-day question is simply not on the table.

How betterment tax is worked out, in plain words

According to the Israel Tax Authority's 2026 guide, betterment tax (mas shevach, מס שבח) is levied on the gain from selling a right in real estate, and the seller owes it. Purchase tax (mas rechisha) is the buyer's, a separate subject covered in the purchase tax article.

The "betterment" is, broadly, the gain on the sale: the difference between the sale value and the purchase value. That difference is only the starting point:

• The law allows certain expenses to be deducted, linked to buying, selling and improving the property. Which ones, and on what terms, is set by the law and the Tax Authority's guidance.
• The law separates the rise that comes from inflation from the real gain, so not every price increase over the years counts as betterment in the same way.

A round example, with no tax worked out: a flat bought for 1,200,000 ILS and sold for 1,800,000 ILS. The difference is 600,000 ILS, but that is not the betterment. The allowed expenses come off it, and the inflation part is separated out. This is where the drawer comes in: an expense with no paper behind it is hard to show, even if it happened. The Tax Authority's guide asks the seller to attach proof of the expenses claimed as deductions.

If "real gain" sounds familiar from investing, there is a reason; the capital gains tax article explains the tax on securities, a different tax with a similar logic.

The sole-residence exemption: check, don't assume

The law has exemptions for selling a qualifying residential apartment (dirat megurim mezaka). A second home follows different rules, and no exemption comes with it by default.

According to the Tax Authority, the sole-home exemption applies when all of these hold:

• The flat is the seller's only one in Israel and the Area (Judea and Samaria).
• The seller has held it for at least 18 months since it became a residential apartment.
• The seller has not sold another flat under this exemption in the previous 18 months.
• The seller is an Israeli resident.

The exemption applies up to a ceiling of 5,008,000 ILS, frozen until 31 December 2027. Tax figures are as of October 2026; rules and ceilings change.

"Our only home" is therefore where checking starts, not the answer. Under the Tax Authority's 2026 guide, the seller files a declaration on the sale that names the exemption being requested and the section of the law it rests on. An exemption is claimed; it does not happen by itself. The Tax Authority's site, under real-estate taxation, sets out the process, the deadlines and the current wording. Your own case is one to check with a lawyer or tax adviser.

The folder: what to keep, starting today

This part has nothing to do with the law and everything to do with you. One folder for the flat, filling up over the years. No project, no lost weekends, no turning every renovation into a tax question.

Step 1: open it. Physical or in the cloud, named after the flat. If there are two of you, somewhere you can both see.

Step 2: put in what you already have. The purchase contract first. Then whatever survives from the purchase, even if partial.

Step 3: from now on, every large expense on the flat goes in on the day you pay it. Not at year end, not "when there's time". An invoice photographed on your phone beats an original in a drawer you cannot find.

Step 4: before deciding to sell, talk to a lawyer. Before the decision, not after. With the folder in hand, the conversation starts from documents rather than memory. What you do with the answer, and whether or when to sell, is your decision.

What may belong in the flat's folder

• The purchase contract
• Proof of purchase tax paid
• Lawyer's and agent's fee invoices from the purchase
• Invoices for major renovations and changes, with the date and the contractor's name
• Permits and plans, if there were any
• A list of large expenses you haven't found paperwork for yet

0 of 6 done

This list is a starting point, not an official one. The folder does not guarantee that any expense will be recognised; it only guarantees you won't be hunting for it. What is recognised, and when, is the Tax Authority's to define.

In AlphaHome: the properties page keeps the purchase details and a dated history of the flat's value. In expenses you can create a "The flat" category with subcategories such as "Renovation" and "Legal", so large costs over the years sit in one place and can be exported the day you need them.

When the old receipts are already gone

Many people stall here: half the drawer is missing, so why start at all? It is not a test you failed. It is where you start.

The old renovation receipts are nowhere. Don't go back with guilt. Gather what you can today: a quick inbox search by the contractor's name, bank transfers, rows you already entered in expenses. Whatever you cannot find goes on the "expenses without paperwork" list, so your lawyer knows they exist.

One of you keeps things and the other doesn't. That is not character; it is location. One shared folder settles most of the argument, because everyone knows where the invoice goes.

A year passed and the folder was forgotten. Give it a fixed moment each year, for example when you update the flat's value. Ten minutes: what was added, what is missing.

What waits for you on the day you decide to sell

Whoever waits for sale day will probably be hunting for the same receipts in the same drawer. Not because something is wrong with them, but because the same approach tends to bring the same result.

The other approach is far smaller than it looks: understand what betterment is, know that the exemption has conditions the Tax Authority publishes, and keep the papers in one place. Betterment tax does not start on the day you sell. It starts on the day you buy, in the folder you keep.

On the day you sit down with the lawyer, you won't need to have become a tax expert. You will only need to put one folder on the table, and hear the right questions asked about papers you already have.

This week, open one folder, physical or in the cloud, named after the flat, and put the purchase contract in it. And in AlphaHome, create a "Renovation" subcategory under "The flat".
