Tax

For a full tax report, the recommended sequence is:

1. tax_get_balances — opening balances (start of tax year) and closing balances (end of tax year)
2. tax_get_dex_trades — all Metal X DEX trading history for the period
3. tax_get_transfers — on-chain transfers, auto-categorized (staking rewards, lending, swaps, NFT sales, etc.)
4. tax_get_rates — local currency conversion rates for each token
5. tax_calculate_gains — compute taxable gains/losses using FIFO or Average Cost
6. tax_generate_report — full report with tax brackets and estimated tax

Or use tax_generate_report directly for a one-shot report that orchestrates all steps automatically.

Data Sources (Mainnet Only)

• Saltant API — historical balance snapshots (liquid, staked, lending, yield farm)
• Metal X API — DEX trade history in CSV format (only filled trades)
• Hyperion API — raw on-chain transfer/action history
• CoinGecko API — historical and current crypto prices (set COINGECKO_API_KEY in .env for full historical access)

Transfer Categories

Transfers are auto-categorized by sender/receiver:

Staking Income Rules

• Block producer rewards (staking_reward): Full amount is income at time of receipt
• Long staking (XPR via longstaking): Only the excess over the staked amount is income. E.g. stake 100 XPR, unstake 150 XPR → income of 50 XPR
• LOAN staking (via lock.token/yield.farms): Same excess-only rule as long staking
• Lending interest: Full amount from lending.loan with interest memo is income

Stablecoin Handling

XUSDC and XMD are pegged to USD — their local currency value uses forex rates (USD/NZD) directly, without CoinGecko. This is more accurate than market-based pricing for stablecoins.

Rate Sources (Priority Order)

1. DEX trades — derives token prices from TOKEN/XMD trade ratios (most accurate, no API limits)
2. Forward-fill — gaps between DEX trade dates use nearest prior known rate
3. CoinGecko — fallback for dates with no DEX data. Without API key: limited to 365 days. With COINGECKO_API_KEY: unlimited history
4. Forex — stablecoins use USD→NZD conversion rate

Delivering the Report

tax_generate_report returns a report_markdown field — a pre-formatted Markdown document with balance sheets, trading summary, income breakdown, tax brackets, and disclaimer. To deliver it:

1. Upload report_markdown via store_deliverable with content_type: "application/pdf" — this is the primary deliverable
2. Upload csv_exports.disposals via store_deliverable with content_type: "text/csv" — disposals CSV
3. Upload csv_exports.income via store_deliverable with content_type: "text/csv" — income events CSV
4. Call xpr_deliver_job with ALL URLs comma-separated (PDF first): "https://ipfs.io/ipfs/QmPDF...,https://ipfs.io/ipfs/QmDisposals...,https://ipfs.io/ipfs/QmIncome..."

IMPORTANT: You MUST complete ALL steps (upload + deliver) in a single run. Do NOT stop after uploading the PDF — you must also upload the CSVs and call xpr_deliver_job. The job is not complete until xpr_deliver_job is called.

The frontend displays the primary file (PDF) prominently and lists additional files as download links.

Known Limitations

• Only filled DEX trades are included (not pending orders)
• NFT: only buy/sell supported (not auctions)
• Liquidations on Metal Lending are not supported
• Escrow payments are tracked but not fully categorized
• Historical pricing accuracy depends on DEX trade activity and CoinGecko data availability

Important Notes

• Always include the disclaimer from the report — this is not tax advice
• Suggest users save CSV exports for the IRD 7-year record requirement
• The region parameter defaults to "NZ" on all tools — pass a different region code when other regions are added
• Set COINGECKO_API_KEY in .env for best historical pricing (free Demo key removes 365-day limit)
• For tokens not on CoinGecko, the tool derives prices from Metal X DEX trade ratios
