Many internationals end up with a mix of accounts (e.g., Trade Republic, eToro, Commerzbank, Schwab/IBKR). Consolidation can cut fees and admin: but it can also reduce flexibility and product access. Here’s how to decide and execute without tax or paperwork headaches.

Quick Answer

  • Consolidate if you’re paying duplicate custody fees, struggling with records, or want a single rebalancing hub.
  • Keep multiple if you need products one broker doesn’t offer (e.g., US-domiciled ETFs, options, multi-currency cash) or you’re a US person avoiding PFICs via a US platform.
  • Transfers between your own German accounts can often be done in-kind (Depotübertrag) so you don’t trigger a sale. Keep pristine records of cost basis and move-in dates.

Benefits of consolidation

  • Lower total fees and fewer “gotcha” charges.
  • Cleaner tax reporting (one annual statement, one set of transaction files).
  • Easier rebalancing and cash management.
  • Less operational risk (fewer passwords, fewer AML checks to maintain).

Reasons to keep multiple accounts

  • Product gaps: Some EU brokers block US-domiciled ETFs (PRIIPs). US brokers may restrict EU-domiciled funds.
  • Currency needs: One broker for USD flows (RSUs, US dividends), one for EUR savings.
  • Feature gaps: Options/futures/treasuries access vs. low-cost mobile ETF savings plans.
  • Regulatory status: US citizens often maintain a US broker to avoid PFIC and keep 1099 reporting.

How to consolidate safely (no tables)

  1. Pick your “hub broker.” Confirm it supports all securities you intend to hold.
  2. Export records from all brokers (full transaction history, corporate actions, dividend logs).
  3. Request in-kind transfer (Depotübertrag) for eligible positions; expect that fractional shares, certain funds, or synthetics may need to be sold and rebought.
  4. Verify cost basis after transfer; correct any missing acquisition dates immediately.
  5. Close or downsize the old account only after your final dividends and tax certificates (Steuerbescheinigung) arrive.

Example decision flow (illustrative)

  • You hold €120k across 3 brokers, paying ~€120/year in duplicate custody + time cost.
  • You choose a low-fee broker with EUR + USD sub-accounts and ETF savings plans.
  • You transfer UCITS ETFs in-kind; you keep a small US account for VTI/VXUS because you’re a US person.
  • Net: simpler admin, maintained access.

Pitfalls to avoid

  • Selling to transfer without modelling tax (realising gains you didn’t need to).
  • Losing fractionals in transfer: know what can/can’t move.
  • Closing an account before the last dividend/tax doc posts.
  • Not saving PDFs/CSVs: audits or future moves need them.

Next steps

  1. List positions per broker; mark which must move in-kind vs sell/rebuy.
  2. Confirm the hub broker supports each ISIN.
  3. Schedule transfers outside earnings/volatility windows if possible.
  4. After settling in one place, use our ETF Investment Calculator to re-map your long-term plan.
