# CPA handoff

- books.export_cpa_package carries every member's and 1099 payee's full TIN from the vault (the K-1 worksheet and the 1099 worksheet). It hands the zip over: run its download command with the folder the human wants it in, then tell them where it is. The viewer's "Export for CPA" makes the same package.
- Never file the package, or a file from it, into the books.
- tin_gaps lists each member or payee whose TIN it lacks and why: collect them (books.set_tin, books.set_w9) and export again.
- Everything in it is as of its as_of: the 1099 worksheet counts the year's payments through that day, and general-journal.iif (the QuickBooks Desktop file) every posted entry from the first through it, closing entries left out. That file is plain ASCII within QuickBooks Desktop's limits: warnings (and the README) say what it writes differently from the books ("Café" as "Cafe", a name cut to 31 characters, a subaccount of another type at the top level, a project's name as its QuickBooks class, the memos grouped); tell the human. Each line's project is its CLASS, the projects declared first as QuickBooks classes. It names no customer or vendor: the README lists the entries on accounts receivable or payable, where QuickBooks may ask the CPA for one.
- With members, the K-1 worksheet is two files: k1-members.csv (each member's capital on the books, with their TIN) and k1-tax-basis-capital.csv (the same capital on the tax basis, as Schedule K-1 Item L reports it: property contributed at the member's adjusted basis, IRC §723, a prepaid contract handed over at its book amount for the CPA to confirm, and the reconciliation from book to tax capital). A line the books can't know (the share of income as figured for tax, always; tax depreciation; a disposal's tax gain; the basis of property no asset records) is left open with what the books have: tell the human the CPA supplies it; never fill it in.
