ETÜ and CME Futures: Controlled Capital Market Transaction?

General information about tax rules, not tax or legal advice. Rules change and every situation is different: check with a qualified adviser in your country before you file.

Two Hungarian traders make exactly the same amount of money on exactly the same contract in exactly the same year. One pays fifteen per cent. The other pays fifteen per cent plus a thirteen per cent social contribution tax on top. The difference is not the trade, the broker fees or the size. It is whether the transaction fits a definition in the personal income tax act called ellenőrzött tőkepiaci ügylet.

That definition is worth more to a Hungarian futures trader than any other single line in the tax code. On a good year the gap between qualifying and not qualifying is close to a month of income. And unlike most tax questions, this one does not depend on how much you earn or how you structure your affairs. It depends on facts about your broker and about your paperwork that you can check today.

The trouble is that almost nothing written about ETÜ has a futures trader in mind. It is written for someone buying shares through a Hungarian bank, where the bank issues a certificate in February and the figures flow into the draft return. If your contracts are on the CME and your broker is in Chicago, none of that machinery exists and you have to reason from the conditions themselves.

What a controlled capital market transaction is

The personal income tax act creates a special category for transactions in financial instruments carried out with, or through, an investment service provider, subject to conditions. Income falling into that category is taxed at the flat fifteen per cent personal income tax rate, and it is not among the income types that carry the thirteen per cent social contribution tax.

The category is deliberately broad on the instrument side. It is not limited to shares. Transactions in financial instruments and in commodities are covered, which is precisely why exchange traded futures are a live question here rather than an obviously excluded one. Swap arrangements are treated separately.

What makes the category special is not just the rate. It is the netting: within the category, your results across the year are aggregated, so gains and losses on different positions offset each other before the tax is applied. And it comes with a loss mechanism, described further down, that reaches back two years. Neither of those exists if your income falls into the general other income box instead.

The conditions, one by one

Strip the statutory language down and you are left with four practical tests. All of them have to hold.

An investment service provider is involved. The transaction is concluded with, or through, an entity carrying on investment services. A retail account with a regulated futures broker satisfies the shape of this. An arrangement where you are not the account holder does not.

The provider operates in a qualifying state. The act refers to providers carrying on activity in Hungary, in another member state of the European Economic Area, or in a member state of the OECD. This is the condition that opens the door to markets outside Europe, and it is the reason the question is asked about the CME at all rather than being closed immediately.

The activity is supervised. The transaction has to be within the scope of activity supervised by the financial supervisory authority of the relevant state. A regulated futures brokerage in a country with a functioning supervisory regime is a very different case from an offshore entity with a slick website.

You can prove it. The provider, and you, have to be able to certify the transactions. This is the condition that fails most often in practice, and it fails quietly: not because the trades did not happen, but because two years later nobody can produce a document in a form that satisfies a Hungarian tax officer.

Read the fourth one again. Everything else on this page is theory. That one is a habit you either build in your first month or do not.

Where a CME contract through a US broker sits

Now the honest part, because you deserve an honest answer rather than a confident one.

The facts line up in a promising direction. The United States is an OECD member state. A US futures brokerage is a regulated entity under a supervisory regime, and exchange traded futures on a designated contract market are financial instruments in any ordinary sense of the phrase. On the face of the conditions, there is a serious argument that a properly documented account with a regulated US futures broker fits.

What nobody can responsibly tell you in an article is that it definitely does, in your case, on your instruments, with your provider. The conditions are cumulative, the certification requirement is real, and the assessment depends on facts about the specific entity you are dealing with. Anyone who tells you flatly that CME futures are ETÜ, or flatly that they are not, is guessing on your behalf with your money.

What to do about it, in order:

• Check what your broker is. Which legal entity holds your account, in which country, under which regulator. This is on your account documents and it takes five minutes.
• Check what it will give you. Ask, before you fund the account, whether it can issue an annual statement of realised results in a form suitable for a tax authority. Most can. Some are much better at it than others.
• Get the position confirmed in writing. A Hungarian tax adviser's written opinion on your specific setup, or a binding ruling from the authority, converts an argument into a document. For a meaningful trading income this is cheap insurance.

Why the szocho question is worth more than the rate

Hungarian personal income tax is a flat fifteen per cent, so the rate is not where the variation lives. The variation lives in whether the thirteen per cent social contribution tax attaches.

Several kinds of investment income do carry it. Interest income is subject to the social contribution tax payable by the individual, and dividends carry it too, with the base capped at twenty four times the minimum wage. With the 2026 minimum wage set at 322,800 forint a month, that cap is a real and calculable number rather than an abstraction.

Income from a controlled capital market transaction is not in that group. That is the whole prize. If your trading income falls into the ETÜ category, the fifteen per cent is the end of the story. If it falls into the general other income category instead, you are looking at the fifteen per cent plus a social contribution charge on essentially the same money, and the way the base is computed for other income where the individual pays the contribution themselves adds another layer of arithmetic.

Put concrete numbers on your own year before you decide this is not worth an adviser's fee. On a trading income of a few million forint, the difference between the two treatments buys the written opinion many times over.

Losses and the two year tax equalisation

The second thing the ETÜ category gives you, after the szocho exemption, is a mechanism for bad years. It is called adókiegyenlítés, tax equalisation, and it works differently from the loss carry forwards you may have seen in other countries.

Instead of carrying a loss forward to reduce a future taxable amount, the mechanism works on the tax itself, looking across the current year and the two preceding years. If you paid tax on controlled capital market income in an earlier year and then made a loss in the same category, the mechanism allows that to be reflected as a credit in your return, within the two year window.

Three practical consequences:

• The window is short. Two years is not much for a trader whose first two seasons are the expensive ones. A loss in year one, with profits only arriving in year four, may be out of reach.
• You have to declare the losing years. A loss that never appeared on a return cannot support a claim later. There is no tax to pay in a red year, which is exactly why the return gets skipped.
• It only exists inside the category. If your income is not ETÜ, this mechanism is not available to you at all, which is another way the classification question compounds.

Work through the mechanics with an adviser the first time you use it, because the calculation is one of the fiddlier parts of the Hungarian return and the rules around it have been amended more than once.

The 20 May return, the forint and the certificate

The annual personal income tax return is due by 20 May for the previous year. The tax authority prepares a draft, which is genuinely useful for salaries and for Hungarian brokerage accounts, and completely silent about a futures account in Chicago. Approving the draft as it stands, when it omits your trading, is filing an incorrect return.

What you have to supply yourself:

• The realised results for the year, aggregated across the category, from your broker's annual statement.
• The forint figures. Your account settles in dollars and the return is in forint. Conversion follows the rules in the personal income tax act using the official National Bank of Hungary rate, and which date applies is worth confirming rather than assuming.
• The costs. Commissions, exchange and clearing fees, and the expenses directly connected to the transactions, kept separately with invoices.
• The evidence. Annual and monthly statements, deposits and withdrawals with dates, and whatever certification the provider can issue.

Build the file monthly. Brokers migrate platforms and archive old accounts, and a statement you cannot download in three years is a position you cannot prove. Keep invoices and payment records for market data, platform licences and any trading system you bought, including each instalment if you paid over several months.

TBSZ, and what it does not cover

Hungarian savers are usually told about the long term investment account, the TBSZ, which reduces the tax on qualifying income after three years and removes it after five. It is a genuinely good instrument, and it is not a solution to anything in this article.

A TBSZ is offered by a Hungarian provider, it is built around a commitment to leave capital in place for years, and its whole economic logic is patience. A futures account is the opposite: margin, daily settlement, positions measured in minutes. The two do not overlap, and a trader who assumes their long term account wrapper covers their futures trading is going to be unpleasantly surprised.

The sensible structure is separation. Long term savings in the instrument designed for them. Trading capital in a separate account, sized as risk capital, with its own records. Never let one conversation contaminate the other, and never fund a margin call from money that was earmarked for the long term account.

Chicago hours on a Hungarian clock

Hungary sits seven hours ahead of Chicago for most of the year, which puts the American session comfortably inside your afternoon.

CME Globex runs the equity index week from Sunday at 17:00 Chicago time to Friday at 16:00, with a one hour halt each day starting at 16:00 Chicago time. In Hungarian time the week opens around midnight on Sunday night, the daily pause falls between 23:00 and midnight, and the week closes around 23:00 on Friday.

The hour that matters is the US cash open, which in Budapest is 15:30, with the American equity cash close at 22:00. That is a workable session for someone with a job: the morning is yours, the first serious move of the American day lands mid afternoon, and you can be finished long before the evening is gone.

One recurring trap. The United States and the European Union do not change their clocks on the same dates, so for roughly three weeks in March and a shorter window at the end of October the gap is six hours and the cash open arrives at 14:30 Hungarian time. Traders miss the most important part of the session over this every year. Put both dates in your calendar today.

Three things to do this week, in this order. Find out which legal entity holds your brokerage account and under which regulator, because that fact drives the whole classification. Ask the broker what annual documentation it can issue. Then take both answers to a Hungarian tax adviser and get the ETÜ question resolved in writing before the amounts are large enough to make the answer expensive.

After that, stop reading about tax. Fifteen per cent, or fifteen plus thirteen, both apply to a number you still have to produce, on two contracts, in one window of the afternoon, over a few hundred sessions. That is the part that takes years and it is the only part that decides the outcome.

Nothing here is tax advice, and the rules on social contribution tax and on investment income have been amended repeatedly in recent years. Verify the current position with the tax authority or with an adviser before you file, and keep whatever answer you get.
