Between your US fund administrator and your German tax advisor, there is a gap that nobody manages. Plainly LP is the coordination layer that fills it — for German and European LPs investing into US venture funds, SPVs, and syndicates.

01 — The problem

Three parties. No coordination.
Everything falls through the gap.

When a German investor puts money into a US venture fund or SPV, three parties become relevant. None of them talk to each other. None of them are responsible for what happens in between.

The US fund administrator handles US tax and operations. Your German Steuerberater handles your German filing. But the translation between the two — the K-1 preparation, the classification analysis, the §180 AO coordination — sits in a gap that nobody manages.

The consequences are real: withholding tax lost permanently, penalties for unmet filing obligations, phantom income tax on money you have not yet received. Most German LPs investing into US funds are exposed to at least one of these risks today.

Plainly LP sits in the middle. Not a tax firm. Not a fund administrator. The coordination layer that makes everything work.

US Fund Admin
Focused on US tax and operations. Not responsible for non-US obligations. Issues the K-1 and stops there.
Plainly LP
The coordination layer. Structural opinion, onboarding, annual service, exit support. One point of contact with visibility across all three parties.
German Tax Advisor
Qualified to file, but unfamiliar with US fund structures, K-1s, and the Rechtstypenvergleich analysis required before any German filing can begin.
02 — Who this is for

Two investor types.
Different risks. One layer.

Track A

Private Investor

Investing as an individual into a US venture fund or SPV. The risk profile is significant. Incorrect classification under German tax law can mean double taxation on returned capital, phantom income tax before any exit, or 30% US withholding tax withheld permanently from every distribution.

Rechtstypenvergleich classification analysis per fund and Operating Agreement
§180 AO unified tax assessment coordination across all German LPs in the fund
W-8BEN/E guidance, filing support, and renewal tracking every three years
K-1 translation and preparation for German tax advisor annually
Hinzurechnungsbesteuerung threshold monitoring for collective ownership
Track B

GmbH Holding

Investing through a German holding company. The exit tax advantage under §8b KStG is significant — around 1.5% effective rate versus 26.4% for a private investor. But it only holds if the structure is correctly maintained and thresholds are actively monitored.

AStG threshold monitoring: total German investor ownership must stay below 50%
Correct GmbH registration with US Fund Admin as non-US entity
W-8BEN/E filed as an entity, not an individual, renewed every three years
§180 AO coordination if transparent classification applies
Fund-level cost deduction coordination for management fees and setup costs
03 — What we do

Four steps.
Nothing falls through.

01Structural opinionOne-time assessment per fund. Vermögensverwaltung vs. Gewerbebetrieb. Transparent vs. opaque classification and tax consequences. All risks identified and translated into a document your German tax advisor can use. Shared across all German LPs in the same fund, keeping the cost manageable.
02OnboardingW-8BEN/E guidance and filing support. Correct registration with the US fund admin. A structured handover document for your local advisor. §180 AO coordination initiated where transparent classification applies and more than one German LP is in the fund.
03Annual serviceK-1 preparation and structuring for your tax advisor each year. Unified tax assessment coordination where required. W-8BEN/E renewal tracking. AStG threshold monitoring when new investors join the fund. One annual check-in. One point of contact.
04Exit supportCollection of all exit documentation from the GP and fund admin. A structured handover package for your tax advisor. Nothing left to coordinate alone at the moment when it matters most.
Free checklist

The 12-item checklist
for German LPs in US funds.

Most German LPs investing into US funds are missing at least three of these twelve items. Some are missing all of them. The consequences range from avoidable — a 30% US withholding tax that should have been zero — to expensive — phantom income tax on money you have not yet received — to genuinely difficult to fix: a filing obligation that has gone unmet for several years.

Covering the Rechtstypenvergleich classification analysis, W-8BEN/E filing requirements, the §180 AO unified tax assessment obligation, AStG threshold monitoring, K-1 preparation, and exit documentation. Twelve items in total. Fifteen minutes to read. Free.

One email. One document. No follow-up sequence.
