TL;DR — Key Takeaways
- →Six document categories: Tax Returns, Bank Statements, Boarding Passes, Receipts, Residency Proofs, Other.
- →Boarding passes are the primary evidence for the IRS Physical Presence Test — don't skip them.
- →500 MB storage limit per account; 25 MB max per file; bank-grade encryption.
- →Documents can be downloaded or deleted at any time — you remain in control.
- →An audit is rare. Scrambling for documents during one is avoidable.
Your 2024 tax return is in an email attachment. Your 2023 is in a Dropbox folder you renamed and can no longer find. Your boarding passes are deleted because you figured you'd never need them. Your lease agreement for your Lisbon apartment is in Portuguese and you never got it translated.
This is not a worst-case scenario. This is just Tuesday for most nomads.
The Audit Vault exists for the day this scattered system gets tested — an IRS notice, a foreign tax inquiry, a visa application that asks for proof of financial ties. That day comes for more nomads than people admit, and the difference between handling it in an hour vs. three weeks of frantic searching is entirely about whether you were organized before it happened.
The Audit Vault in keepmore.money is encrypted, category-organized document storage built for exactly this situation. Upload once, find instantly.

The vault uses six categories, because different situations demand different documents:
- Tax returns: filed returns, amended returns, any written correspondence with tax authorities
- Bank statements: foreign accounts, wire transfer records, proof of financial presence in a country
- Boarding passes and flight records: proof of physical presence — not optional for FEIE filers
- Receipts: business expenses, major tax-relevant purchases
- Residency proofs: lease agreements, utility bills, local registration documents
- Other: anything that doesn't fit cleanly above
The categories matter in practice. An IRS Physical Presence Test audit requires location documentation by day. A Schengen dispute requires entry and exit stamps. A foreign tax inquiry wants to see your lease and bank statements. Knowing where things are when someone is asking under pressure is what matters.
The Boarding Pass Problem
Tax courts have rejected FEIE claims because the filer couldn't prove where they were on specific dates. Not unusual dates — just random dates the IRS asked about. The Physical Presence Test requires 330 days outside the US, and that burden of proof is yours.
Digital boarding passes, paper boarding passes photographed with your phone, flight confirmation emails — all of these work. None of them survive in your email inbox reliably. Five minutes after each flight to upload and categorize beats digging through archived Gmail eight months later.
Storage and Security
Files are encrypted at rest. 500 MB per account, 25 MB per file. Enough for years of documents. You can download anything at any time, delete what you no longer need, and access it from any device.
Audits are uncommon. But immigration paperwork, visa renewals, bank account openings in new countries, and accountant requests are not. The vault earns its keep long before any official inquiry appears.
