Abgeltungssteuer: How Germany Taxes Investment Income

In Germany the tax on your investment income is usually gone before you ever see the money. Your bank works it out, deducts it and sends it to the tax office, and for most people that is the whole story: no form, no declaration, nothing to remember in spring. The convenience has a cost, though. A deduction you never see is a deduction you never check, and there are a handful of very ordinary situations in which the automatic version takes more from you than the law actually asks for.

What Abgeltungsteuer actually means

Start with the word, because it explains the design. Abgeltung means settlement, or discharge. Once your bank has withheld the tax on a payment of interest, on a dividend or on a gain you realised, your obligation on that income counts as settled and the income does not have to travel any further into your income tax return. The tax that is physically deducted is called Kapitalertragsteuer, the tax on capital yields. Abgeltungsteuer is the name for its effect, which is closing the matter. The law spells it with one s in the middle. Almost everybody, banks included, writes Abgeltungssteuer with two. They mean the same thing.

The second design decision is that investment income is treated at one flat level rather than being stacked on top of your salary and taxed in your personal band. A senior manager and a shop assistant pay the same on the same dividend. That is unusual, and it is on purpose: capital crosses borders easily, and one rate a bank can apply mechanically at the moment of payment is far cheaper to collect than a rate that depends on the rest of somebody's year. The trade-off cuts both ways: gentle on a high earner, rough on somebody with almost no other income, which is why the law carries a correction for the second case. That comes up later.

What counts as investment income

Interest is the simplest case: a savings account, a Tagesgeld account, a bond coupon. Distributions come next, meaning dividends from shares and payouts from funds. The one that catches people is the realised gain, what an English speaker would call a capital gain: the profit you lock in when you sell shares, funds, bonds or certificates for more than you paid. Certain income from derivatives sits in the same box. What is not in the box is a gain you have not taken. A share that has doubled on paper is not taxed until you sell it. Accumulating funds are the exception worth knowing about, because Germany charges a notional amount each year (the Vorabpauschale) precisely so that a fund which never distributes anything cannot defer tax forever. One thing to keep straight while reading fund factsheets: the dividend yield quoted anywhere is a gross figure, before any of this happens. If payouts are the reason you hold the position at all, the mechanics of building around them are covered separately in dividend investing for beginners.

The two surcharges that ride along

The headline tax is not the whole deduction. The Solidaritätszuschlag is calculated on the tax itself rather than on your income, so it behaves like a percentage of a percentage and it lands automatically wherever the tax lands. Church tax, Kirchensteuer, applies if you are a registered member of a religious community that levies it, and this is where people are genuinely surprised: your bank never asks you about your religion. Once a year it sends an automated query to the Bundeszentralamt für Steuern, which returns your affiliation as a stored attribute, and the bank deducts accordingly. You can block that query by filing a Sperrvermerk. Blocking it does not remove the obligation, it only moves it, because you then have to declare the church tax yourself through your Finanzamt.

The allowance does nothing until you ask for it

Germany shelters a first slice of investment income per person each year, the Sparerpauschbetrag, and doubles it for couples assessed together. The part people miss is that it is not applied on its own. Your bank keeps withholding until you file a standing instruction with that bank, the Freistellungsauftrag, telling it to pay you gross up to the amount you allocate. It needs your Steuer-Identifikationsnummer, and most brokers let you file it and change it online inside the Depot in about a minute.

The complication is that the instruction goes to a bank and not to the tax office. Somebody with a savings account at one institution and securities accounts at two others has to cut one allowance into three pieces and guess in advance where the income will actually turn up. Allocate too little to the account that ends up producing the income and tax gets withheld that you did not owe. It is not lost, but the only route back is a tax return in which you ask for it. So the practical habit is simple: every time you open, close or start feeding a new account, look at the split again.

Losses do not vanish, they go into a pot

Your bank runs loss accounts for you in the background, the Verlusttöpfe. Close a position at a loss and the amount drops into a pot, where it is set against later gains at that same bank automatically, first inside the year and then carried forward for as long as the account exists. The pots are separate and the separation matters. A loss on an individual share can only be offset against a gain on individual shares, while losses on funds, bonds and other instruments go into a general pot. A further pot keeps track of foreign withholding tax that is available to be credited.

What no bank can do is look inside another bank. Picture a year in which you close a position at a profit at one broker and close a different position at a loss of exactly the same size at another. Economically you finished flat. The first broker still withheld tax on the full gain, and the second broker is sitting on a loss with nothing at hand to offset it against. Nothing joins those two facts up by itself. You ask the second broker for a Verlustbescheinigung, the certificate that hands the loss over to you instead of leaving it parked in the pot, you submit both banks' figures with your return, and the Finanzamt does the netting. That request has a statutory cut-off in December, so it is a decision you make before the year ends, not one you discover in spring.

When your broker is not German

A broker based outside Germany normally withholds nothing, because it is not plugged into the German collection machinery. That does not make the income untaxed. If you are tax resident in Germany, the income is taxable in Germany, and the declaring is now your job rather than a bank's. The form is the Anlage KAP attached to your income tax return, with the Anlage KAP-INV alongside it for fund income that no domestic bank has already settled. Treating the silence as a loophole is a poor plan. Under the Common Reporting Standard, banks in participating countries report account information to their own authorities, which pass it to the country where the account holder lives.

Three situations where filing is worth the hour

The first is an unused allowance. If your income was spread across banks and one Freistellungsauftrag was set too low, a return is how you claw the difference back. The second is the case above, losses at one broker sitting opposite gains at another. The third is the Günstigerprüfung, literally the more favourable check. You tick a box on the Anlage KAP and the Finanzamt compares two treatments, the flat one your bank already applied and your ordinary personal income tax treatment, then applies whichever leaves you paying less. You cannot come out worse for asking, which is the entire point of it.

That third one earns its keep in a year when your other income is unusually low. A student with an inherited portfolio. Somebody on parental leave. A gap between two jobs, or an early retiree living off savings. Those are precisely the people for whom a flat treatment designed with a high earner in mind produces the wrong answer, and the check exists to correct it.

There is a fourth case, and it depends on what you own rather than on your circumstances. A dividend from a foreign company is usually taxed once by the country that company sits in, before the money ever reaches your broker. A double taxation treaty limits how much that country is allowed to keep, and Germany credits part of what was withheld against what you owe at home, so the same income does not get fully taxed twice. German banks handle a good deal of this automatically. Anything the source country kept above the treaty level is not credited and has to be reclaimed from that country's own tax authority, which is paperwork worth doing only when the sum justifies it.

What this changes about how you invest

Tax lands when you realise, so activity carries a price that a paper portfolio never shows you. Selling one fund to buy a nearly identical one, or rebalancing enthusiastically every quarter, turns an untaxed paper gain into a taxed real one and shrinks the capital that keeps compounding afterwards. Accumulating funds push that moment further out, because they reinvest internally instead of paying you (the trade-off is laid out in accumulating versus distributing ETFs, and the compounding effect in dividend reinvestment), though the Vorabpauschale exists to stop that deferral running forever. Do not turn the idea upside down, though. A bad investment with attractive tax treatment is still a bad investment. Tax is a tiebreaker between two sensible choices, never a reason to make a silly one.

Where to find the numbers this article leaves out

You will have noticed that there is not one rate, allowance or threshold anywhere above. That is deliberate. These figures move by legislation, sometimes at short notice, and a confidently stated number that quietly went stale is worse than no number at all. The current ones are published by the Bundesfinanzministerium, and the law itself, the Einkommensteuergesetz for the general rules and the Investmentsteuergesetz for funds, is free to read on gesetze-im-internet.de. Your own Finanzamt answers questions about your specific case, ELSTER is the official portal where the return is filed, and a Steuerberater is who you pay when the amounts at stake justify the fee. Confirm the current figure with one of those, or with a qualified adviser, before you act on anything here.

Two things are worth doing this week. Open each account and check what Freistellungsauftrag is actually filed there, because a split you set when you had one broker is almost certainly wrong now that you have two. Then, if one account is carrying a loss while another had a good year, put the Verlustbescheinigung request in your calendar for early December. Everything else can wait for the annual Steuerbescheinigung, the document that finally tells you what was taken and on what.
