Scope (Read this first)

  • Federal partnership returns only: Form 1065 + Schedule K-1s.
  • Simple partnerships only: no tiered structures / complex waterfalls yet.
  • State filings: handled separately and scoped after review.
  • Complex deals: reviewed separately (may be quoted or declined).

Generate federal partnership tax returns using structured templates. Designed for simple SPVs and funds. Complex cases reviewed separately.

1065 & K-1 Generator — Quickstart

This section covers producing Form 1065 and partner K-1s using the Gainvest generator.

1) Prepare your inputs

  • P&L — normalized accounts with mapping codes (e.g., 1a, 2, 9, etc.).
  • Balance — beginning/end amounts grouped by asset, liability, equity.
  • Partners — one row per partner with identity, ownership %, capital, liabilities, and allocation overrides.

Tip: On Gold tier, we preprocess all three files for you.

2) Upload & validate

  • From your Dashboard, upload P&L, Balance, and Partners under your entity/year.
  • Set Line G/H flags (initial/final/amended; cash/accrual) in Return Options.
  • Confirm the partner count matches (we show it on 1065 line “Number of Schedules K-1”).

3) Generate PDFs

  • Click Generate 1065 to produce the return PDF.
  • Click Generate K-1s to produce one K-1 per partner.

4) Review & file

  • Verify allocations, capital analysis (begin → contributions → income/loss → withdrawals → end), and liabilities sections.
  • On Silver/Gold, Gainvest files the 1065 and K-1s for you.

Technology

High-level components used by the Gainvest app and generator.

  • Frontend: Django templates (HTML/CSS/JS). Chat preview on the homepage, authenticated chat after login.
  • Auth & Data: Firebase Auth (web + mobile), Firestore (partners, books, return options, file refs).
  • PDF Engine: Python (pypdf) overlay on IRS fillable PDFs (Form 1065 + Schedule K-1), coordinate maps with right/left alignment helpers.
  • Storage/Links: GCS object storage with signed URLs for generated PDFs.
  • Payments: Stripe Checkout for annual entity subscriptions (Bronze/Silver/Gold).
  • Ops: Cloud Run or VM for API, REST endpoints for generation, logging, and webhooks.

Reliability & gotchas

  • Unique filenames: K-1s use {slug}-{index}-{timestamp}.pdf to avoid overwrite/caching issues.
  • Signed URL expiry: Generated links expire. Re-download from the dashboard if needed.
  • Booleans: Line G/H and Schedule B flags must be explicit (we write “X” or blank to the PDF layer).

GNV Ledger & API

The GNV ledger records activity and provides a simple API for balance, blocks, and mining.

Endpoints

  • POST /mine — Submit prompt + wallet to mint GNV.
  • POST /transfer — Transfer GNV between wallets.
  • GET /balance/<wallet> — Wallet balance.
  • GET /supply — Total circulating supply.
  • GET /blocks — Block history.
  • POST /dao/register_model — Register mining-eligible models.
  • POST /dao/vote — Submit a DAO vote.

Example

curl -X POST https://mainnet.gainvest.ai/mine \
  -H "Content-Type: application/json" \
  -d '{"wallet":"gnv1xyz...","prompt":"Hello Gainvest!"}'
