How to Fund Interactive Brokers
from Europe (2026)
Funding IBKR is straightforward once you treat it like a bank transfer, not an app top-up. This guide covers the clean SEPA workflow, what actually delays deposits, and the failure modes that waste days.

TL;DR — do this, avoid that
- Use SEPA bank transfer for EUR funding — cheapest, cleanest path.
- Create the deposit notification in IBKR first, then send the transfer.
- Send from a bank account in your exact legal name.
- Copy the reference / memo exactly — do not shorten it.
- First transfer: send a small test amount before large funding.
- Set up a recurring SEPA deposit via the portal for monthly DCA.
- Third-party transfers — someone else’s bank account.
- Missing or wrong reference — the most common cause of unmatched deposits.
- Revolut, N26, or any digital-wallet bank — IBKR does not support these.
- Funding in the wrong currency repeatedly — friction compounds.
- SWIFT when SEPA is available — intermediary fees and delays.
Quick reference: what to do in each situation
| Situation | Do this | Why |
|---|---|---|
| You’re in Europe, sending EUR | SEPA (EUR) | Cheapest and cleanest for EU banks. Typically same-day to 1 business day. |
| SEPA isn’t shown as an option | Use the method IBKR shows for your entity | IBKR entities differ — follow the Client Portal instructions exactly. |
| First ever deposit | Send a small test amount | Verifies name and reference matching before large transfers. |
| You invest monthly (DCA) | Set up recurring SEPA | IBKR supports recurring notifications — reduces manual work each month. |
| Transfer not credited / unmatched | Check reference + name match | Missing or wrong reference is the most common cause of delays. |
| You’ll buy USD assets long-term | Fund EUR → convert inside IBKR deliberately | Avoid repeated conversions on every buy. Convert in batches via IdealPro. |
| Tempted to use SWIFT | Avoid | Intermediary fees and delays are more common — only use if SEPA isn’t available. |
Step-by-step: fund IBKR via SEPA from Europe
Seven steps. The order matters — create the deposit notification before you send anything.
Most European investors fund in EUR via SEPA, then convert inside IBKR when needed. Banks outside the Eurozone may need to use SWIFT instead — check the Client Portal for your specific entity’s options.
Go to Transfer & Pay → Transfer Funds → Deposit Funds. Choose Bank Transfer / SEPA (exact wording varies by entity) and select EUR as the currency.
The notification generates your deposit instructions and ensures IBKR can automatically match your incoming transfer. You can also save it as a recurring transaction for monthly DCA. Do this before sending any money.
You’ll see: beneficiary name, IBAN, BIC/SWIFT, bank name and address, and a required reference/memo. Copy-paste every field — do not retype or abbreviate anything.
Use a bank account in your exact legal name. Do not send from Revolut, N26, or any digital-wallet bank — IBKR explicitly does not support these institutions and payments will be delayed or rejected.
Typical timing is same-day to 1 business day. Keep your first deposit small to confirm the pipeline works — once proven, scale with confidence.
If buying USD assets, convert in batches rather than on every purchase. Use the Forex trader (IdealPro) for larger amounts to get competitive spreads. Frequent small conversions create drag that compounds over time.
How long do SEPA deposits to IBKR take?
SEPA is designed to make EUR transfers within the Single Euro Payments Area equivalent to a domestic transfer — but timing still depends on several variables.
- Wrong or missing reference — IBKR cannot auto-match the payment to your account, triggering manual review.
- Sender name mismatch — the sending account name doesn’t match the IBKR account holder name exactly.
- Digital-wallet or third-party transfer — not supported, and IBKR will delay or reject these.
- Weekend timing — SEPA processing slows or pauses depending on the banks involved.
- No deposit notification created — the transfer can still arrive but matching is slower without one.
What you actually pay — and where costs hide
IBKR doesn’t charge a deposit fee for incoming SEPA transfers. The real costs sit elsewhere: your bank’s outgoing transfer fee, unnecessary currency conversions, and the interest threshold worth knowing about.
| Cost area | What it looks like | How to reduce it |
|---|---|---|
| SEPA deposit fee (IBKR) | €0 — IBKR does not charge for incoming SEPA | Nothing to reduce |
| SEPA transfer fee (your bank) | Often free at EU banks, but not guaranteed | Use a bank with free or cheap SEPA outgoing transfers |
| Intermediary / SWIFT fees | Can appear with SWIFT instead of SEPA | Always prefer SEPA for EUR; use SWIFT only if unavailable |
| FX conversions | Cost lives in spread and frequency | Convert deliberately in batches; use IdealPro for larger amounts |
| Idle cash interest threshold | IBKR pays interest on EUR cash above €10,000 only | Deploy sub-threshold cash, or compare with Trade Republic for smaller balances |
The 6 most common funding failures — and how to fix them
IBKR uses the reference/memo to automatically match incoming funds. If it’s missing or mangled, the deposit sits “unassigned”. Fix: contact IBKR support immediately with proof of transfer and the exact sending details. Going forward, always copy-paste the reference — never retype it.
Transfers from someone else’s account are a compliance trigger. Fix: only fund from a bank account in your exact legal name. If you used a joint account, ensure your name is clearly on the account.
IBKR explicitly does not support digital-wallet banks (Revolut, N26, etc.). Payments from these often arrive without sufficient payment details. Fix: send from a traditional EU bank account. This is a hard constraint — there is no workaround.
Sending currency X to instructions meant for currency Y causes delays and possible conversion fees. Fix: use the deposit instructions that match your sending currency and method exactly.
Your bank transfer can still arrive, but matching is slower and manual review is more likely. Fix: always create the notification before sending. If already sent, create it immediately with matching details.
Some banks flag broker transfers as higher-risk. Fix: call your bank to pre-approve the transfer and save the IBKR beneficiary as a trusted recipient. If persistent friction remains, switching sending banks is often the cleanest solution.
Funding checklist
- ☐ Deposit notification created in the IBKR Client Portal before sending
- ☐ Correct currency and method selected (Bank Transfer / SEPA for EUR)
- ☐ Sending from a traditional EU bank — not a digital-wallet institution
- ☐ Sending bank account name matches your IBKR account holder name exactly
- ☐ Reference / memo copied exactly as shown — not shortened or retyped
- ☐ First transfer is a small test amount
- ☐ FX plan in place: convert deliberately inside IBKR, not on every single purchase

Frequently asked questions
What is the best way to fund IBKR from Europe?
For most European investors, a EUR SEPA bank transfer is the cleanest and cheapest method. IBKR does not charge a deposit fee for incoming SEPA transfers. Create the deposit notification in the Client Portal first, then send from a traditional EU bank account in your exact legal name, using the reference/memo exactly as shown.
How long do SEPA deposits to IBKR take?
Typically same-day to 1 business day. Same-day is possible if the transfer is sent early and processed cleanly. Weekends, public holidays, missing references, and name mismatches can stretch this to 2–3 business days or longer.
Can I fund IBKR from Revolut or N26?
No. IBKR does not support deposits from digital-wallet banks such as Revolut or N26. Payments from these institutions often lack sufficient payment details and are likely to be delayed significantly or rejected entirely. Use a traditional EU bank account instead — this is a hard constraint with no workaround.
Why did my IBKR deposit fail or get delayed?
The most common causes are a missing or incorrect reference/memo, a name mismatch (including third-party transfers), use of a digital-wallet bank, or a wrong currency/method combination. Check these first before assuming IBKR has lost the funds. If unresolved after 1 business day, contact IBKR support with your transfer proof and exact sending details.
Do I need to convert currency before buying USD assets on IBKR?
Usually yes — if you fund in EUR and want to buy USD-denominated assets. The key is converting deliberately and infrequently rather than incurring a small conversion cost on every individual purchase. For larger amounts, use IBKR’s Forex trader (IdealPro) to get competitive spreads. Repeated small conversions create drag that compounds meaningfully over a long investment horizon.
Does IBKR pay interest on EUR cash deposits?
Yes, but only on EUR cash above €10,000. If your balance is below that threshold, you earn nothing on idle cash. For smaller portfolios, the interest benefit is limited compared with alternatives like Trade Republic that pay interest from the first euro. Factor this in when deciding how much cash to hold uninvested at IBKR.
What is the safest first deposit strategy for IBKR?
Send a small test transfer — €50–100 is enough — to validate the full route: your bank to IBKR, with the correct reference and name. Once credited and confirmed in your cash balance, scale deposits with confidence. Keep the transfer confirmation and reference in case support ever needs to trace a payment.
