Investor identity becomes a graph
Residency, treaty position, certificate type and expiry, classification, and entry path all differ per investor, and each one changes what that investor can be paid.
Your investors file in one country. Your assets are in another.
That is the fund Basis is built for: US structures with LATAM and global investors first. Everything downstream gets harder, the filings multiply and the calendar stacks, and the operational detail nobody models becomes your liability. Here is what we do about each piece.
- A live Delaware fund with a Mexican feeder and foreign investors
- Dual-rail distributions rehearsed end to end
- Four withholding regimes modeled
- Documents and portal in English and Spanish, enforced in the build
- Founders who launched a bank in Mexico
What breaks
Income needs characterization by source and type
The same distribution can carry different withholding for every partner, driven by where the income came from and what kind it is. Real estate adds its own regime on top.
Entity structure becomes a graph
Feeders and parallel vehicles mean the register is no longer a list of names. The look-through has to hold from the investor to the asset and back.
The calendar stops being two dates
Domestic funds live around one filing and one extension. A foreign partner adds withholding filings that cannot wait for the extension, and offshore reporting with its own clock.
Money arrives short and never reconciles
Cross-border payments arrive net of intermediary fees, in amounts that no longer match the notice. Someone has to explain every difference, forever.
Documents multiply by locale
Every notice and statement now exists per investor, in the investor's language, under the investor's data-protection regime.
What Basis does about each
One tax identity per investor
Residency, treaty position, certificate type and expiry, classification, and entry path (direct or through a feeder) held in one record that documents and distributions draw from.
Withholding recorded per investor, applied per distribution
Withholding amounts are recorded from your tax preparer and applied at the line level, so each investor's statement shows gross, withheld and net separately.
A register that holds the structure
Feeder vehicles run as look-through administration on the same register: one system, no second set of books, and the chain from investor to asset stays verifiable.
The calendar, modeled
Reporting obligations are generated per fund with their real deadlines and tracked to completion, so the stacked calendar below is a checklist, not a surprise.
Expected payments that match themselves
Wire references are created with each notice, and incoming payments match against expected amounts automatically. A short arrival is flagged with its difference, not buried.
Documents generated per investor, per language
Notices, statements and the portal in English and Spanish, generated from the same numbers for every investor.
The deadline map
The calendar a US fund with foreign partners actually lives. Only someone who has lived it draws it; verify each date with your tax preparer for your own structure.

The tightest clock in the stack

A W-8 expires on the last day of the third succeeding calendar year
Not on a rolling 36-month clock, which is a known industry bug
Late information returns are penalized per return, applied separately to the IRS and payee copies, with no annual maximum for intentional disregard. On 200 investors, the arithmetic gets institutional fast.
What Basis does not do
- Basis computes no tax and characterizes no income.
- Basis signs no return. Your tax preparer stays the author and the signer, with a scoped workspace of their own.
- Basis gives no legal, tax or investment advice.
- Withholding amounts are recorded from your tax preparer and applied as recorded.
