How it works — 3 simple steps
From first login to finished tax report in minutes, not hours.
Import Your Data
Connect your wallet with one click (MetaMask, Phantom, Coinbase), link exchanges via API, upload CSVs, or paste addresses. We auto-detect blockchains and sync everything.
We Calculate Your Taxes
Auto-classify transactions, discover missing prices from 9,400+ DEX pools, find missing wallets, create tax lots, and calculate gains/losses — all automatically.
Download Your Report
Preview everything free. Download a complete Filing Package (Form 8949 + Schedule D in one PDF), or export for TurboTax, FreeTaxUSA, H&R Block, TaxAct, Cash App Taxes, international reports (HMRC, ATO, CRA, Anlage SO), or 20+ other formats.
Know Exactly Where You Stand
The #1 complaint about crypto tax software: the gap between “automatic” and reality. Our Tax Health Dashboard closes that gap with a guided workflow that actually gets you to 100%.
Your tax readiness score tells you exactly what needs fixing before you file. Not a vague progress bar — a real score based on your actual data quality.
Smart Classification
Label one transaction, we find and label 30+ similar ones automatically. Rules you create apply retroactively to existing transactions too.
Guided Fix Workflow
Five sections in priority order. Fix one section and improvements cascade downstream — missing prices resolve, classifications update, gains recalculate.
You Control Recalculation
Make all your corrections first, then recalculate when you're ready. No surprise recalcs mid-edit that change everything you just fixed.
Mark as Reviewed
Track what you've verified. Your readiness score climbs as you review transactions — so you know exactly when you're done.
Everything you need for crypto taxes
From importing your first transaction to filing with the IRS — we handle it all.
One-Click Wallet Auto-Detect
Instantly detects installed wallets — MetaMask, Phantom, Coinbase, Rabby, Trust, Rainbow, and more. Import all EVM + Solana addresses with one click. Or paste any address and we auto-detect the blockchain across 550+ chains.
16 Exchange API Integrations
Coinbase, Gemini, Binance, Kraken, KuCoin, OKX, Crypto.com, and Bybit. Secure read-only API keys.
250+ Import Formats
If your exchange isn't API-connected, we likely have a CSV importer for it. Covers virtually every exchange and wallet.
5 Cost Basis Methods
FIFO, LIFO, HIFO, LTFO, and Specific ID. Compare side-by-side in the tax simulator to find what saves you the most.
Tax-Loss Harvesting
Automatic detection of harvestable losses with wash sale rule compliance, including substantially identical asset tracking (ETH/WETH, SOL/mSOL). Weekly email alerts when opportunities arise.
IRS Audit Defense Package
One-click download of your complete audit bundle: Form 8949, methodology statement, blockchain-verified transaction logs.
One-Click Filing Package
Download a complete, IRS-ready filing package — Cover Page, Form 8949, and Schedule D merged into one PDF. Works with every major tax software. Filing confidence checklist verifies your data before you file.
1099-DA Reconciliation
Compare your exchange 1099-DA against your Form 8949 to verify totals match. Guidance on what to do if they differ. Ready for the new IRS reporting requirements.
Pre-Trade Tax Simulator
See the exact tax impact before you sell. Compare timing strategies — how much could you save by waiting for long-term rates?
Live Portfolio Dashboard
Year-round holdings view with asset allocation, cost basis breakdown, and realized performance tracking.
Wallet Discovery
We scan your transaction history and automatically find wallets you may own but haven't added yet. One click to add them — preventing false taxable events from internal transfers.
CPA Sharing Portal
Invite your accountant with a secure token. They get a read-only dashboard to review your data — no login required.
NFT Tracking & Valuation
Automatic detection of NFT mints, buys, and sales with confidence-scored fair market valuations. High-confidence prices auto-applied, low-confidence flagged for your review.
Referral Program
Give $10, get $10. You both earn $10 credit when your friend subscribes. Applied automatically at checkout.
On-Chain Avatar Identity
Automatically displays your ENS or Proton avatar. The only crypto tax tool that shows your on-chain identity — no uploads needed.
IRS 2025 Per-Wallet Cost Basis
Comply with IRS Rev. Proc. 2024-28 requiring per-wallet cost basis tracking. Cost basis automatically follows tokens between wallets — lot splitting, multi-hop transfers, and dust thresholds handled. Auto-enforced for 2025+.
Safe Harbor Wizard
Step-by-step Rev. Proc. 2024-28 compliance tool. Allocate cost basis across wallets, generate election statements, and ensure your 2025 transition meets IRS safe harbor requirements.
Transfer Matching UI
Manually match cross-wallet transfers and propagate cost basis between wallets. Visual interface for linking send/receive pairs when automatic matching misses a connection.
CSV Import Pre-Validation
Upload any CSV and get instant feedback: column mapping confidence scores, duplicate detection, cost basis continuity checks, and format auto-detection — all before a single row is imported.
Automated Price Discovery
Auto-recognize 18,000+ tokens via CoinGecko mapping. Missing prices? We query 9,400+ DEX AMM pools plus GeckoTerminal across 47 networks (Ethereum, Polygon, Arbitrum, Base, Optimism, BSC, and more). Alcor (9,247 pools), SimpleDEX (200+ pools), Jupiter, Aftermath, and Noodles. We price tokens other platforms show as $0.00.
Data-Health Alerts
Your Tax Health Dashboard surfaces missing prices, unclassified transactions, and zero-cost-basis lots before you calculate. Guided fix workflow resolves issues in priority order — no more discovering problems at filing time.
Regulatory Monitoring
We monitor tax authorities daily for crypto regulation changes — so your tax calculations always reflect current rules.
DeFi LP Position Dashboard
Dedicated /defi-positions page — the first in crypto tax — tracking LP positions, impermanent loss, fees earned, and entry/exit values across 10 protocols: Uniswap V3, Aave V3 (Ethereum), Jupiter V6, Raydium, Meteora, PumpFun (Solana), Cetus, Turbos (Sui), Alcor DEX & SimpleDEX (XPR). Three view modes: Protocol Groups, Card Grid, Data Table.
Transaction Merge
Select any two transactions and merge them into one. Fixes duplicate imports, split fills, and partial transfers in seconds. Fully undoable.
Sortable Columns
Click any column header on the Portfolio or Transactions pages to sort instantly. Sort holdings by value, gain/loss, or cost basis — or sort transactions by date, amount, type, or price.
Price Collision Protection
Contract address-based price lookups prevent scam tokens from sharing a ticker with real ones. Fake token auto-flagging and price sanity checks block phantom gains from airdropped dust and honeypot tokens.
Spam & Dust Auto-Filter
Solana dust, phishing airdrops, honeypot tokens — automatically detected with configurable threshold and filtered before they break your report. Bulk dismiss with one click, whitelist false positives, and auto-rules prevent re-detection on future syncs.
Auto-Classification Engine
No weeks of manual fixes. Our classification engine automatically identifies swaps, transfers, staking, LP positions, airdrops, and bridge transactions. Pattern recognition learns from your corrections and applies them across all wallets.
Staking Classification — 10+ Chains
Instruction-level staking parsing across Solana, Ethereum, Sui, Polkadot, Cardano, NEAR, Tron, Aptos, TON, and 30+ Cosmos networks. Detects STAKE, UNSTAKE, REDELEGATE (non-taxable validator moves), and CLAIM_REWARD from actual on-chain instructions — not just program IDs. Uncertain transactions are flagged for review, never silently misclassified.
Liquid Staking Toggle
Choose whether liquid staking deposits (ETH → stETH, SOL → mSOL, ATOM → stATOM) are taxable disposals or non-taxable exchanges. Toggle per-chain in Settings. Most platforms force one answer for everyone — we let you decide. Applied to all historical transactions.
Tax Health Dashboard
Readiness score (0-100%) with guided fix workflow. Smart labeling cascade classifies 30+ similar transactions at once. Five priority sections where fixing one cascades improvements to the next. Classification rules apply retroactively.
Cost Basis Review
Dedicated view of tax lots needing attention: zero cost basis, pending prices, and lots flagged for review. Filter by issue type and resolve problems before they become IRS questions.
Smart Price Resolution
Contract-address price lookups via DeFi Llama when symbol matching fails — essential for SPL tokens and DeFi assets. Tiered anomaly detection: 50x threshold for listed tokens, 500x for memecoins. Auto-recalculation after price backfills.
Excel & CSV Export
Export all transactions across all wallets as formatted Excel spreadsheet or CSV. Color-coded rows, auto-filters, 18 columns including wallet labels, fees, and tags. Hand it to your accountant and they can actually read it.
Realize Loss on Worthless Coins
Got rugged? One-click total loss realization for worthless, bankrupt, or lost tokens. Creates proper $0-proceeds disposals with correct Form 8949 classification. Categorize as rug pull, bankruptcy, lost wallet, or worthless.
Portfolio Analytics Dashboard
Top 5 and bottom 5 assets by ROI, portfolio allocation percentage breakdown, and per-coin realized + unrealized P&L. Customizable widgets you can drag, rearrange, or hide.
Capital Loss Carryforward
Automatically tracks IRS $3,000/year loss deduction limit across tax years. See your available carryforward balance and how it applies to future returns.
Business vs Personal Income
Tag income transactions as personal or business. Business crypto income routes to Schedule C. Perfect for freelancers, miners, and mixed-use portfolios.

What traders are saying
“I was paying $199/yr to Koinly for 3,000 transactions. Switched to BST and got the same features for $99. The auto-classification caught DeFi swaps Koinly missed entirely.”
— Active DeFi Trader
4 wallets across Ethereum, Arbitrum & Solana
“The free preview showed me my full tax report before I paid anything. No other tool does that. I could see every transaction classified before committing.”
— First-Time Crypto Filer
Bitcoin & Coinbase, ~200 transactions
“Set up 6 wallets in under 10 minutes. The spam filter caught 400+ airdrop tokens that would have inflated my transaction count on other platforms.”
— Multi-Chain Portfolio Manager
6 wallets, 2,800+ transactions
“Per-wallet cost basis tracking was the dealbreaker for me. With the new IRS rules starting 2025, I needed a tool that actually supports Rev. Proc. 2024-28. BST was the only one.”
— Crypto-Focused CPA
Managing clients across 12+ blockchains
“I had staking rewards on Cosmos and Solana that other tools completely missed. BST auto-detected epoch rewards and even caught my stETH rebasing. Saved me hours.”
— Staking Enthusiast
Cosmos, Solana & Ethereum staking
“The tax-loss harvesting tool found $4,200 in unrealized losses I didn't know I had. Wash sale detection gave me confidence the savings were legitimate.”
