Tax reporting for prediction market makers.

Market making means fills on both sides of the book, all year. We rebuild every one from the venue's own record, and introduce you to a CPA for the structure and filing questions that come with running a book.

Your book, your forms, and a CPA.

We build the numbers. Structure and filing advice come from a CPA, working from the same file.

Reporting

Every fill, both sides of the book.

Every fill, fee and settlement, with lots matched first in, first out.
Positions still open at December 31, marked at the venue's published close.
Results by account and by year, with a transaction CSV for your spreadsheet or tax software.

Forms

The forms for each common treatment.

Form 8949 for standard capital treatment, one row per lot.
Form 6781 for Section 1256, with the December 31 mark.
A gambling session log for §165(d).
The transaction statement behind every figure.

Advice

A CPA for structure and filing.

Whether to trade through an entity, and how to file, are questions for a CPA.
We introduce you to one we approve of who already works with prediction market traders.
Your transaction file goes with you, already built.
The CPA advises you directly, not Realize.

Several accounts or an entity? We scope it.

If you trade across venues, accounts or entities, tell us on the call. We come back with the work and a price for it.
