Saxo Bank and German Taxes — 2025 Filing Guide

1. The Saxo tax situation in Germany

The relevant entity is Saxo Bank A/S, headquartered in Hellerup, Denmark, supervised under Danish rules. Saxo's own materials identify Saxo Bank A/S as the parent company of the Saxo Group; client agreements are with the relevant Saxo entity depending on the customer's residence and entity relationship (Saxo Bank — Licence details).

For a German tax-resident private investor with an account at Saxo Bank A/S, Saxo is operationally a foreign custodian / foreign paying platform for the German tax return. German Kapitalertragsteuer mechanics are tied to the inländische paying or custody institution — Saxo A/S is not in that role. You self-declare investment income on Anlage KAP for non-fund items and Anlage KAP-INV for ETFs and other investment funds (ELSTER — Anlage KAP / KAP-INV 2025 help).

CRS / Danish reporting is informational. Saxo states that it reports information to the Danish Tax Agency, and for non-Danish residents in CRS countries may report account balances, trading volumes, interest, dividends / coupons and other financial income for onward exchange with foreign tax authorities (Saxo — CRS / Danish reporting). That does not replace your German Anlage KAP / KAP-INV obligation.

2. What Saxo doesn't withhold for you

For private capital income at Saxo Bank A/S, the following German taxes are not generally withheld:

• 25 % Kapitalertragsteuer (§ 32d EStG).
• 5.5 % Solidaritätszuschlag.
• Kirchensteuer.
• Vorabpauschale for fund / ETF units (§ 18 InvStG) — Saxo A/S is not a domestic institution administering the units.

Source-country withholding is a different matter. Saxo says dividends are credited with applicable standard withholding taxes depending on the stock domicile, but withholding taxes or capital-gains taxes are left to clients to handle / report in their country of residence (Saxo — Withholding tax). Saxo specifically states it does not offer relief on bond coupon payments (Saxo — Bond coupon payments). Source-country tax may be creditable in Germany via Anlage KAP line 41, but it is not German tax.

You cannot apply a German Freistellungsauftrag at Saxo A/S in any practical way. The Sparer-Pauschbetrag is applied through your assessment — Section 8.

3. Reports to download from Saxo

Treat Saxo reports as source data, not as a German Anlage KAP / KAP-INV mapping. Even Saxo's own Tax Voucher is broker-style evidence, not a German Steuerbescheinigung.

Tax Voucher

Broker document summarising investment income (dividends, interest, capital gains) and deducted taxes. Saxo says it can be requested in the platform via account-service requests (Saxo — Request a Tax Voucher). Useful evidence; not a German Steuerbescheinigung. It may not apply German line logic, German FIFO nuances, German fund taxation, or German treatment of derivative losses.

Account Statement

Full cash and account movements; the master reconciliation report (Saxo — Where to find account reports). Cash movements, transfers, FX conversions and corporate actions need manual interpretation.

Portfolio Report

Performance, P/L, positions, costs, balances. Saxo notes positions are calculated on a mark-to-market basis in client currency. Mark-to-market P/L is not automatically German taxable realised P/L; German tax usually needs realised transactions, FIFO, acquisition costs, disposal proceeds, and EUR conversion (Saxo — Mark-to-market P&L method).

Transactions / Trades Executed / Closed Positions

Core source for acquisitions, disposals, option closings, futures, CFDs and realised trades (Saxo — Trading conditions / closed positions). Saxo Switzerland's support page states that its Closed Position report calculates P/L on FIFO and warns that this may not match the local tax authority's principle (Saxo — FIFO method). Even if Saxo A/S reports similarly, German calculations should be independently checked.

Dividends and corporate actions

Saxo lists corporate-action event types including cash dividend, stock dividend, spin-off, stock split, delisting, and rights-type events (Saxo — Dividends and corporate actions). German tax treatment of spin-offs, stock dividends and reorganisations may differ from the platform label and can require issuer-specific tax treatment.

Bond Coupon Payments

Coupons and any withholding tax on fixed-income instruments. Saxo states it does not offer relief on bond coupon payments (Saxo — Bond coupon payments). Coupons and bond disposals are different German tax categories; source tax must be checked for creditability.

Forex Rollovers

Saxo says FX spot trades do not settle and that open positions are rolled forward with Tom/Next swap points and financing of unrealised P/L (Saxo — Forex Rollovers). This points to derivative-like / rolling margin rather than physical foreign-currency holdings — German classification differs (Section 5).

Carrying Cost Details

Relevant for short listed options and / or short futures, where Saxo says overnight positions may incur carrying costs (Saxo — Carrying cost).

Annual Cost Report / Cost Summary

Reconciles commissions, FX spreads, borrowing costs, CFD financing, carrying costs and withholding taxes (Saxo — Cost Summary). Cost categories are MiFID / broker-cost categories, not always German tax-deductible categories. § 20(9) EStG generally excludes actual Werbungskosten beyond the Sparer-Pauschbetrag.

Minimum filing pack: annual account statement, trades / transactions export, dividend report, coupon report, interest report, FX rollovers, cost report, all withholding-tax details, year-end positions, and a separate German tax-calculation schedule.

4. Currency conversion

Your German return is in euros. Do not simply take Saxo's base-currency P/L as the taxable amount.

For securities and other capital assets under § 20 EStG, the statute requires a transaction-based computation: for non-EUR transactions, disposal proceeds are converted into EUR at the disposal date, and acquisition costs are converted into EUR at the acquisition date (EStG (PDF); § 20(4) also contains the FIFO rule for fungible securities).

For dividends, coupons and cash interest in foreign currency, convert the gross income and any withholding tax into EUR using a documented rate on the payment / inflow date; BMF Abgeltungsteuer guidance points to the Devisenbriefkurs on the inflow date (BMF — Abgeltungsteuer (14 May 2025)).

For sales of shares, bonds, ETFs, certificates and similar assets, compute the German gain from EUR-translated acquisition costs and EUR-translated disposal proceeds — not from a foreign-currency gain translated only once at the end. § 20(4) explicitly points to acquisition-date and disposal-date conversion.

For actual foreign-currency cash (USD, GBP, CHF, etc.) held as cash, § 23 EStG can apply when sold, converted or used within one year (private disposals; FIFO rule for identical foreign-currency amounts).

For Saxo FX spot / margin FX, Saxo's documentation says the spot trades do not settle and are rolled forward with Tom/Next swap points and financing of unrealised P/L. The BMF guidance distinguishes actually delivered foreign currency from FX transactions aimed at differential settlement, which can be Termingeschäfte. A Saxo user can have both: ordinary foreign-currency cash balances from securities trading, and separate FX trading positions. Do not merge them without analysis.

5. Per-asset-class treatment for Saxo users

Direct shares

Dividends from shares are capital income under § 20(1) EStG; gains from selling shares are capital gains under § 20(2). For Saxo:

• Dividends → Anlage KAP Z19 for foreign capital income from foreign banks; foreign tax not yet credited → Z41.
• Share sale gains → calculated using German FIFO and EUR acquisition / disposal conversion; reported additionally in the share-disposal line Z20.
• Share sale losses → Z23; ELSTER says losses from selling shares may be offset only against gains from selling shares.

ETFs and investment funds (KAP-INV)

Fund taxation runs through the Investmentsteuergesetz: § 16 InvStG defines investment income as distributions, Vorabpauschalen and gains from selling fund units. ETFs and funds at Saxo go on Anlage KAP-INV, with fund categories (Aktienfonds, Mischfonds, Immobilienfonds, Auslands-Immobilienfonds, Sonstige). Enter gross amounts before partial exemption; the Finanzamt applies Teilfreistellung per § 20 InvStG:

Bonds, coupons and cash interest

Bond coupons and cash interest are generally capital income under § 20 EStG. For Saxo, take gross coupon / interest and any source tax from the coupon / interest reports — the Bond Coupon Payments report is the right starting point, and Saxo says it does not offer tax relief on coupons. Bond sales / redemptions are not share disposals; they go in the non-share disposal line.

Listed options

The BMF Abgeltungsteuer guidance treats options in detail. Option premiums and transaction costs are acquisition costs for the option buyer; closing, exercise, cash settlement, expiry and writer positions are each analysed separately (BMF — Abgeltungsteuer (14 May 2025)).

Futures, forwards, swaps and CFDs

The BMF guidance lists options, swaps, foreign-exchange forward transactions, forwards, futures and CFDs as examples of Termingeschäfte under § 20(2) Nr. 3. CFDs are described as contracts speculating on price movements of an underlying without owning the underlying.

FX trading at Saxo

FX is one of the most error-prone areas. Two cases:

1. Actual foreign-currency cash — holding USD / GBP / CHF as cash can create a separate § 23 issue when sold, converted or used within one year. § 23 contains a FIFO rule for identical foreign-currency amounts.
2. Margin FX / rolled Saxo FX spot — Saxo says spot positions do not settle and are rolled forward with swap points and financing. The BMF guidance distinguishes actually delivered foreign currency from differential-settlement FX transactions, which can be Termingeschäfte.

A Saxo user may have both. They should not be merged without analysis.

6. Stocks and bonds in Anlage KAP

Verified 2025 ELSTER labels for the foreign-broker section of Anlage KAP:

ELSTER explicitly says foreign tax not yet credited belongs in Anlage KAP Z41, not Anlage AUS, including foreign tax on KAP-INV income.

Werbungskosten note. § 20(9) EStG generally excludes actual Werbungskosten beyond the Sparer-Pauschbetrag for private investors. Margin interest, account costs, platform costs and similar items shown on Saxo cost reports are usually not freely deductible. Costs directly connected with a disposal can reduce a § 20(2) gain — analysed transaction-by-transaction.

7. Vorabpauschale specifics for 2025

For ETFs and funds at Saxo A/S, the Vorabpauschale is not automatically taxed by a German custodian. § 18 InvStG deems it received on the first working day of the following calendar year.

Two timing facts that matter for your 2025 return

• The 2024 Vorabpauschale is deemed received on 2 January 2025 and belongs in your 2025 return. ELSTER's 2025 KAP-INV help confirms the 2024 Basiszins of 2.29 % and the resulting calculation rate of 1.603 %.
• The 2025 Vorabpauschale will be deemed received on 2 January 2026 and belongs in your 2026 return. The BMF letter of 10 January 2025 sets the 2025 Basiszins at 2.53 %, giving a calculation rate of 1.771 % (BMF — Basiszins 2025).

Formula

• Basisertrag = January 1 fund value × Basiszins × 70 %.
• Mehrbetrag = (December 31 fund value − January 1 fund value) + distributions.
• Vorabpauschale = min(Basisertrag, Mehrbetrag) − distributions; floor at 0; cap at the Mehrbetrag.
• Acquired during the year: reduce by 1/12 for each full month before the month of acquisition.

Enter the gross Vorabpauschale by fund type in KAP-INV Z9–Z13; the tax office applies the Teilfreistellung. Use the Section 4 worksheet ("Ermittlung der Vorabpauschalen zu den Zeilen 9 bis 13") if the broker statement does not provide a German-rule figure.

The line-53 trap on later sales

When you sell a fund, the Section 5 worksheet (≈ "line 53" in PDF form) deducts prior Vorabpauschalen during the holding period before partial exemption — to avoid double taxation. For Saxo A/S custody, the deduction is allowed only to the extent those Vorabpauschalen were actually reported and taxed, or were absorbed by the Sparer-Pauschbetrag. Document this. Skipping past Vorabpauschalen costs you here.

8. The Sparer-Pauschbetrag trap

For 2025, the Sparer-Pauschbetrag is €1,000 single / €2,000 jointly assessed (§ 20 (9) EStG). At a German broker, you can apply this through a Freistellungsauftrag. At Saxo, you cannot. The allowance is applied through your assessment.

Old €20,000 Termingeschäfte loss-cap. ELSTER's 2025 help reflects that the relevant § 20(6) restrictions for term transactions and certain worthless-asset losses were repealed. Continue to document term-transaction losses, but do not apply the old cap mechanically. For 2021–2024 open assessments and disputes, check the transitional / legal status with your adviser.

9. Common mistakes Saxo users make

1. Treating the Saxo Tax Voucher as a German Steuerbescheinigung. ELSTER's domestic-certificate logic is tied to German withholding. Use Saxo reports as source data, not as a copy into German domestic-bank lines.
2. Assuming CRS reporting means the German return is already done. Saxo reports to the Danish Tax Agency and may report under CRS for non-Danish residents — the taxpayer still has to declare the correct German tax amounts.
3. Using Saxo's mark-to-market portfolio P/L as taxable P/L. German tax generally needs realised transactions, FIFO and transaction-date EUR conversion.
4. Forgetting KAP-INV and Vorabpauschale for foreign-held ETFs. ETFs at Saxo are not handled by a German custodian; KAP-INV is required for investment-fund income not subject to domestic withholding, including foreign custody cases.
5. Applying the old €20,000 derivative loss cap to 2025. ELSTER 2025 says the relevant § 20(6) restrictions were repealed. Continue to report term losses, but do not apply the old cap mechanically.
6. Mixing actual FX cash with FX margin trading. Saxo FX spot positions may be rolled and financed, while actual foreign-currency cash can raise § 23 issues. Separate ledgers needed.
7. Misclassifying option events. Option exercise, expiry, cash settlement, closing trades and writer premiums each have different German treatments per BMF guidance.
8. Putting foreign withholding tax in the wrong form. For capital income under the flat-tax system, ELSTER says not-yet-credited foreign tax belongs in Anlage KAP Z41, not Anlage AUS.
9. Ignoring source-country withholding on coupons and dividends. Saxo may receive income after source withholding; for bonds, Saxo states it does not offer tax relief on coupons. Check whether foreign tax is creditable in Germany and whether a reclaim is needed abroad.
10. Assuming Saxo Switzerland tax statements apply to Saxo Bank A/S Denmark. Saxo Switzerland says its tax statements are for Swiss tax returns only.

10. Calculate your Vorabpauschale now

For ETFs and funds held at Saxo A/S, open the calculator, enter your 2024 fund values and any 2024 distributions, and you get the 2025-return Vorabpauschale and the KAP-INV / KAP figures to copy into ELSTER. The calculator does not handle options, futures, CFDs or FX rollovers — those go on Anlage KAP and need transaction-level analysis (see Sections 5–6).
