Our take

Fyn (formerly BearTax)

Fyn, which previously operated under the name BearTax, delivers a structured platform designed to resolve complex cryptocurrency tax reporting and Web3 accounting challenges. The software emphasizes high volume transaction ingestion, connecting directly to exchanges, custodial accounts, and self custody blockchain addresses. By automating the normalization of trading, staking, mining, and transfer activity, Fyn simplifies the creation of tax forms such as IRS Form 8949. While the software provides clear reporting workflows and custom ledger integration for corporate accounting teams, individual users with occasional trading activity might find the tiered transaction limits restrictive. Fyn serves as a reliable calculation engine for users seeking transparent audit trails, provided they are prepared to review and classify unusual onchain transfers manually.

Koinly

Koinly delivers a comprehensive tax calculation and portfolio management solution designed to handle messy crypto transaction histories. By connecting read-only API keys, public wallet addresses, and CSV records, the platform consolidates activity across centralized trading venues, self-custody addresses, and smart contract protocols. The core strength rests in its extensive regional compliance settings, which support country-specific accounting methods such as FIFO, LIFO, and share pooling rules in the United Kingdom or average cost basis in Canada.

While the service offers free transaction syncing and balance monitoring, downloading official tax filing forms requires an annual tax year license. Pricing scales by total transaction count, which can become costly for automated bot traders or active yield farmers. For individuals seeking clear tax liability calculations and downloadable reporting forms, Koinly provides an established and reliable operational setup.

Tax engine capabilities and asset tracking

Fyn (formerly BearTax)

Fyn functions as a non custodial tax reporting suite and institutional digital asset accounting platform. The system operates by processing read only transaction data across hundreds of digital assets, fiat pairs, and cross chain protocols. Users connect their centralized exchange accounts via read only API keys or upload historical trade histories using standard CSV files. The platform also reads public wallet addresses directly across networks including Bitcoin, Ethereum, and major layer two ecosystems.

Once transaction histories are imported, Fyn applies standardized cost basis accounting methodologies such as first in first out, last in first out, and highest in first out. The software identifies internal transfers between user owned accounts to avoid triggering accidental taxable events. For businesses and decentralized organizations, Fyn extends beyond personal capital gains reporting by supporting double entry bookkeeping, chart of accounts customization, and enterprise resource planning software synchronization. Complex decentralized finance actions, including liquidity pool provisioning and wrapped token staking, are ingested into the dashboard for user verification and cost basis assignment.

Koinly

Koinly operates as a cloud-based reporting hub that ingests transaction records across thousands of digital assets, tokens, and non-fungible tokens. The system integrates with major global exchanges like Binance, Coinbase, Kraken, and Bybit through read-only API connectors, alongside dedicated blockchain scrapers for Ethereum, Solana, Bitcoin, Polygon, and dozens of other layer-1 and layer-2 networks. Users simply paste their public wallet addresses or upload standard spreadsheet exports to populate their transaction ledger.

Once imported, the calculation engine identifies transfers between owned accounts, tags staking rewards, flags airdrops, and calculates realized gains or losses against historical fiat market rates. The interface surfaces real-time balance tracking, unrealized profit metrics, and cost-basis distributions across multiple accounts. For decentralized finance participants, the software tracks liquidity pool deposits, token swaps, and yield claims, though complex multi-hop interactions or non-standard automated market maker transactions may require user inspection and custom tag assignment.

Subscription tiers and transaction pricing

Fyn (formerly BearTax)

Fyn structures its commercial pricing around annual subscription tiers based on the total number of transactions processed within a specific tax year. Unlike trading venues or payment brokers, the software does not take spreads, handle user funds, or assess withdrawal fees. Instead, costs are determined entirely by the operational scale of the user portfolio and the depth of reporting functionality required.

Basic consumer plans cater to casual investors with limited annual transaction counts, unlocking standard Form 8949 generation and basic audit logs. Higher tier individual plans expand transaction caps to accommodate high frequency trading, automated bot activity, and extensive decentralized exchange operations. For corporate clients, Web3 startups, and accounting firms, Fyn provides specialized enterprise licenses. These business packages incorporate advanced ledger integrations, multi entity support, team access controls, and custom data mapping tools. Users should assess their lifetime trade frequency before selecting a plan, as exceeding a tier threshold requires an account upgrade to generate final reports.

Koinly

Koinly structures its commercial pricing around yearly tax reports rather than recurring monthly platform access. The baseline free plan allows individuals to connect unlimited wallets, review portfolio allocations, and preview estimated capital gains without entering payment information. However, exporting official tax schedules, Form 8949 documents, or specialized international filings requires purchasing a single tax year plan that matches the user's total transaction volume for that period.

Paid tiers start at entry-level pricing for low-volume accounts handling up to 100 transactions, scaling upward to mid-tier options covering 1,000 transactions, and premium tiers accommodating 10,000 or more records. Additional transaction packages can be added for high-volume trading accounts. Users should note that licenses apply per tax year, meaning historical amendments or subsequent annual filings require separate package purchases, although existing reports can be regenerated freely if transactions within that specific year are adjusted.

Data security and permission boundaries

Fyn (formerly BearTax)

Because Fyn operates purely as an analytics and tax calculation service, it never takes custody of digital asset balances or manages private keys. Security parameters center entirely on protecting imported financial records and establishing strict external access permissions. Centralized exchange connections require read only API credentials, directing account holders to disable withdrawal, transfer, and trading permissions during key setup. This architectural boundary prevents the software from initiating unauthorized transactions or affecting external exchange account balances. Read only ingestion is intended to support that account data access remains purely diagnostic and administrative throughout the reporting period.

Data transmissions between client browsers, external blockchain nodes, and processing servers rely on standard transport layer security encryption protocols. Stored financial records, API secrets, and generated tax schedules reside within encrypted cloud database environments protected by continuous perimeter monitoring. User profiles incorporate multi factor authentication controls to prevent unauthorized access to sensitive financial summaries and tax identification numbers. The platform parses public blockchain ledger histories directly without requesting smart contract write permissions or seed phrases, which eliminates smart contract wallet draining risks. Internal access policies restrict data handling strictly to authenticated calculation processes, maintaining clear administrative barriers across all user data sets.

Koinly

Because Koinly functions strictly as an accounting and tracking service, it does not provide custodial storage or hold user funds. The platform operates on a zero-custody framework, eliminating direct exposure to private keys or withdrawal authority. When connecting centralized exchange accounts, users generate read-only API credentials that explicitly disable trading and fund withdrawal permissions, ensuring that credentials cannot execute asset movements or manipulate balances. This structural separation keeps user assets under personal control across external wallets and connected platforms.

Account security relies on standard operational helps protect, including mandatory email confirmation protocols and optional two-factor authentication via authenticator apps. Stored transactional data and API keys are encrypted at rest and during transit between systems. While the platform stores historical transaction records, public addresses, and balance snapshots to generate tax schedules, users retain control over connected data sources. Subscribers can disconnect individual API integrations, delete specific transaction batches, or purge their complete account profile at any time through standard account preferences.

Geographic availability, compliance, and customer assistance

Fyn (formerly BearTax)

Fyn is available globally over web interfaces, supporting tax frameworks and accounting standards for multiple jurisdictions, including the United States, Canada, Australia, and the United Kingdom. Its calculation engine accommodates local regulatory requirements by providing jurisdiction specific capital gains calculations and localized tax year parameters. The software supports standard tax exports compatible with mainstream consumer tax filing software as well as professional tax preparation suites used by certified public accountants.

Customer support is delivered primarily through an online help center, documentation libraries, and digital support ticketing channels. Users encountering missing pricing data, broken CSV formats, or unclassified smart contract transfers can access troubleshooting guides or submit support tickets directly through their user dashboard. While self service resources cover common API errors and data formatting questions, enterprise clients receive dedicated onboarding assistance and custom data mapping support to helps support their general ledgers align with corporate reporting timelines.

Koinly

Koinly supports crypto tax compliance across more than twenty formal jurisdictions, offering dedicated reporting formats tailored to local tax authorities. For taxpayers in the United States, the platform exports IRS Form 8949, Schedule D, and comprehensive capital gains summaries compatible with popular tax software like TurboTax and TaxAct. Similarly, users in the United Kingdom, Canada, Australia, Germany, France, and other territories can generate localized reports adhering to specific local calculation rules.

Customer assistance is provided primarily through an in-app help center, searchable documentation libraries, and ticketed email support, with live chat options available depending on plan tier and team availability. Response times may lengthen during peak tax filing seasons in major markets. The platform also offers an accountant portal, allowing certified public accountants and tax professionals to access client accounts directly, adjust cost-basis tags, and review reconciliation warnings before final submission.

Choosing the appropriate reporting plan

Fyn (formerly BearTax)

Selecting the correct Fyn subscription involves matching your yearly onchain activity and centralized exchange trading frequency to the appropriate tier. Retail investors who execute straightforward spot trades on centralized platforms can select entry level personal tiers to produce annual tax documents efficiently. Active yield farmers, automated bot traders, and Web3 treasury managers should evaluate higher volume individual or corporate tiers that accommodate thousands of raw blockchain transactions. Corporate entities and accounting firms require enterprise subscriptions that include multi entity support, chart of accounts mapping, and advanced enterprise resource planning integration exports. Reviewing your combined transaction counts across all self custodial wallets and exchange accounts before checkout prevents unexpected mid reporting tier upgrades and administrative delays.

Koinly

Choosing an appropriate Koinly plan depends entirely on annual transaction frequency and decentralized protocol usage. Casual buy-and-hold investors with only a few dozen spot trades per year can comfortably utilize the entry-level tier. Active decentralized finance traders who generate hundreds of micro-transactions through staking, routing swaps, or automated yield compounding should calculate their expected yearly volume carefully to avoid unexpected tier upgrades.

Because the free tier allows full ledger synchronization prior to checkout, users can import all exchange connections and wallet addresses first to determine their exact transaction tally before selecting a paid plan. This setup helps avoid overpaying for unnecessary capacity while verifying that all assets and cost-basis lines are accounted for accurately.

Who it suits

Fyn (formerly BearTax)

Fyn is well suited for active cryptocurrency traders, multi chain Web3 participants, and corporate finance teams who require automated transaction reconciliation across diverse wallets and exchanges. The platform fits users who want transparent cost basis calculations, downloadable IRS Form 8949 schedules, and standard double entry ledger exports without relinquishing custody of their digital assets. Freelancers and contractors who receive payments in digital tokens can track regular income schedules alongside capital gains liabilities. Decentralized finance participants with extensive cross protocol transactions benefit from the software aggregation features and wallet parsing tools. Accounting professionals managing several client accounts can leverage the consolidated dashboard tools to prepare accurate regulatory filings. It serves high volume investors who prioritize systematic data normalization over manual spreadsheet calculations.

Koinly

Koinly is well suited for crypto investors, self-custody decentralized finance users, and tax advisers who need automated aggregation across fragmented exchange accounts and multi-chain wallets. It offers strong value for taxpayers in supported jurisdictions looking to generate pre-formatted capital gains schedules and audit trails without manually calculating complex cost basis figures.

However, active high-frequency algorithmic traders and bot users generating tens of thousands of transactions annually may find per-transaction tier pricing less cost-effective than enterprise software, while non-crypto tax filers will find no utility in its specialized digital asset toolset.
