Osakesäästötili and Derivatives: Why Futures Are Excluded

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.

You opened an osakesäästötili because everyone told you to. It is the account where nothing is taxed until you take money out, the one your bank markets with a compound interest chart, the one that finally gave Finnish households something close to the Swedish ISK. Then you go looking for the MES contract in the order ticket and it is not there. No futures, no options, no ETFs. You call the bank and they confirm it, politely and without much explanation.

It is not a platform limitation and it is not your bank being conservative. The account is built on a statutory list of what it may hold, and derivatives are not on it. Here is what the equity savings account can and cannot contain, why the exclusion is structural rather than accidental, and where CME futures actually get taxed when you trade them from Finland.

What the account may hold

The osakesäästötili holds two things: cash, and shares listed on a stock exchange. That is the whole inventory. The Tax Administration is explicit that you can put only money into the account, not securities you already own, so you cannot migrate an existing portfolio into it either.

Instrument	Allowed in an osakesäästötili
Listed shares	Yes
Cash	Yes
Futures and options	No
ETFs	No
Mutual fund units	No
Bonds	No
Unlisted shares	No

Two further limits bite in practice. You may deposit a maximum of 100 000 euros into the account over its life, counted as money paid in rather than as the value of the holdings, so a portfolio that grows past the ceiling is fine. And you may hold exactly one account. Having more than one at the same time triggers a punitive tax of 10 euros per day for each account beyond the first, which is the kind of penalty that looks trivial for a week and unpleasant after a year of not noticing. The rules are set out on the Tax Administration's page on the equity savings account.

Why derivatives were left out

The exclusion makes more sense once you see what the account is actually doing. Its advantage is not a lower rate. It is the removal of the tax event. Inside the account you can sell a holding and buy another without triggering anything, and dividends land untaxed and stay invested. Tax arrives only when you withdraw, and only on the profit portion of what you withdraw.

For that mechanism to work, the provider has to be able to say at any moment what you paid in, what the account is worth, and therefore what proportion of any withdrawal is profit. That accounting is straightforward when every holding is a share with a price, an owner and a purchase cost. It is much less straightforward with a futures position, which has no purchase cost in the same sense, settles variation margin daily against the clearing house, and can be worth a large negative number without you having paid anything for it.

There is also a policy reading, and it is not hidden. The account was created to move Finnish household savings into listed equities, not to provide a general tax-deferred wrapper for trading. Funds and ETFs were left out for the same reason, which is why an investor who wants broad index exposure inside the wrapper has to buy listed shares one at a time rather than a single index product. Whatever you think of that design, it is the design, and a derivatives trader is outside it by intention.

If you want to check the wording yourself rather than take a bank's word for it, the Finnish-language version of the Tax Administration's guidance on the osakesäästötili is the primary reference, and it is blunter than most of what your provider will send you. It states directly that only money can be paid in and that the holdings are listed shares, which is the sentence the whole exclusion rests on.

Worth adding: this is also why losses behave oddly inside the account. During the life of the account there are no per-trade taxable events, so there is no per-trade loss to deduct either. A bad position inside the wrapper reduces the account's value and therefore reduces the profit portion of future withdrawals, which is a form of relief, but it is not a deduction you claim against other capital income in the year it happens.

There is one more consequence people discover late. Because the account may hold only listed shares, an investor who wants diversified exposure has to assemble it share by share, and an investor who has been using ETFs for years cannot simply move that strategy into the wrapper. That is a separate complaint from the derivatives one, but it comes from the same rule, and it explains why the account is more popular with people who buy a handful of Helsinki names than with anyone running a systematic approach.

What a withdrawal costs

When you take money out, the provider splits the withdrawal into returned capital and profit, in proportion to the state of the account. Tax is withheld at 30 percent on the profit portion. That withholding is provisional: your final rate depends on your total capital income for the year.

Capital income in the year	Rate
Up to 30 000 euros	30 percent
Above 30 000 euros	34 percent

The proportional split is worth a worked example, because people expect withdrawals to come out of their original capital first and they do not. Say you paid in 20 000 euros over a few years and the account is now worth 30 000. A third of the account is profit. Withdraw 6 000 euros and 2 000 of that is treated as profit, taxed at 30 percent, so 600 euros is withheld and 5 400 reaches your bank. You cannot choose to take out "just your own money", and you cannot choose to realise the loss-making holdings first to shrink the profit share.

One point that surprises people: dividends inside an osakesäästötili do not get the partial exemption that applies to dividends from listed companies held in an ordinary book-entry account. Inside the wrapper the dividend simply increases the account value and is taxed later as part of the profit on withdrawal. Whether the account beats an ordinary account therefore depends on how much you trade and how long you leave the money alone, not on a blanket advantage.

Where CME futures actually get taxed

Outside the wrapper, in an ordinary brokerage or futures account, taxed as capital income at the same 30 and 34 percent rates. That much is simple.

The loss side is where you should slow down. Finland's general rules for capital losses on securities are clear: a loss is first deducted from capital gains, then from other capital income if there are not enough gains, and anything unused is carried forward for five subsequent years. There is also a small-transactions rule, under which sales totalling no more than 1 000 euros in a calendar year are exempt, with the mirror consequence that losses are not deductible either when the year's acquisition costs are 1 000 euros or less. And there is the deemed acquisition cost, 20 percent of the sale price for holdings under ten years and 40 percent for holdings of ten years or more, which you may use instead of the real purchase price. Those rules are explained on the Tax Administration's page on selling shares.

Do not assume all of that transfers cleanly to a cash-settled index future. A future is not a share, there is no transfer of ownership, and a deemed acquisition cost calculated as a percentage of a sale price does not have an obvious meaning when the contract settles in cash against a settlement price. The treatment of gains and losses on derivatives depends on the type of contract and where it trades, and Finnish rules distinguish between contracts traded on a regulated market and other arrangements. This is the point at which a blog should stop and a source should start: read the Tax Administration's detailed guidance on the taxation of derivatives, or put the question to Verohallinto in writing with your actual contract specification attached, before you assume a loss on an ES contract behaves like a loss on a Nokia share.

What is not in doubt is that the profit is taxable capital income and that declaring it is your job.

Two accounts, two sets of rules

Most Finnish traders who end up here run both: an osakesäästötili for long-term equity holdings and an ordinary account for anything the wrapper will not take. That is a perfectly sensible arrangement, but the two behave differently enough that it is worth seeing them side by side.

	Osakesäästötili	Ordinary account with futures
What it holds	Cash and listed shares only	Anything your broker offers, including CME futures
When tax arises	On withdrawal, on the profit portion	As results arise, year by year
Deposit ceiling	100 000 euros paid in	None
Number of accounts	One, with a daily penalty for extras	As many as you like
Losses	No separate deduction during the life of the account	Deductible under the ordinary capital loss rules, subject to how the contract is classified
Prefilled on your return	Usually yes, for a Finnish provider	No, for a foreign broker

The line that matters most for an active trader is the timing one. The wrapper's whole benefit is deferral, and deferral is worth something only if you leave the money alone for years. A trader who withdraws profits regularly to live on captures very little of it. A trader who cannot use the wrapper at all, because the instruments are excluded, loses nothing they were realistically going to get.

Which is the quiet conclusion here. Being shut out of the osakesäästötili as a futures trader sounds like a penalty and mostly is not. What you lose is a deferral you would not have used. What you gain by paying attention instead is the ordinary capital loss machinery, which the wrapper does not give you at all.

Reporting a foreign broker in OmaVero

Your pre-completed tax return arrives in spring with a printed deadline on it, usually one of several dates in May depending on which group you are in. Finnish providers report to the Tax Administration, so domestic share sales and equity savings account withdrawals tend to appear already. A futures broker in Chicago reports nothing to Finland.

That means you add it yourself. In OmaVero you open the pre-completed return and enter the missing investment income. On paper the equivalent is Form 9A for gains and losses on securities sales, domestic and foreign. The Tax Administration is direct about where responsibility sits: you check the pre-completed return and you report anything missing, including from foreign brokers. Its page on reporting information on your investments sets out the process and the forms.

Practical advice, and it is the same every year. Export a full trade log in January, not in May. NinjaTrader 8 will produce a trade performance report per instrument and per period, which is exactly the reconstruction you will otherwise be doing from screenshots. Save the broker's annual statement, save the monthly ones behind it, and record the euro conversion method you used and stick to it for the whole year. A US futures account is denominated in dollars and the return is in euros, so the conversion is part of your numbers whether you think about it or not.
