Bitcoin.Tax vs Dune

As a specialized software utility, Bitcoin.Tax processes transaction histories across spot exchanges, wallet addresses, and institutional trading accounts. The application is built to ingest data using read-only API connections and structured CSV uploads. It catalogs historical spot trades, mining income, staking rewards, compensation payments, hard forks, gifts, and donations into unified ledgers mapped against historical fiat prices.

The system supports major digital currencies such as Bitcoin, Ethereum, and standard altcoins, pairing historical fiat valuations to match transaction timestamps. Once data is imported, users can run calculations using FIFO (First In, First Out), LIFO (Last In, First Out), HIFO (Highest In, First Out), Average Cost, or Specific Identification accounting methods. Filers who require specific lot selection can adjust matched trades manually to reflect their tax strategies within relevant legal boundaries.

In addition to standard capital gains schedules, the platform includes dedicated modules for income calculation and closing position reports. These outputs allow filers to differentiate between short-term capital gains, long-term holdings, ordinary income, and capital loss carryovers, providing essential documentation for annual filings.

Dune operates primarily as a web-based data workspace that abstracts raw blockchain data into clean relational schemas. Supported networks span major Layer 1 and Layer 2 ecosystems, including Ethereum, Solana, Bitcoin, Arbitrum, Optimism, Polygon, and Base. Raw blockchain data, encompassing block headers, transaction receipts, and log traces, is parsed into structured tables via DuneSQL, an optimized query engine based on Trino. This structure allows researchers to query event logs, contract method calls, and transfer traces directly.

Beyond raw blocks, the platform provides curated datasets through its Spellbook repository, a community-maintained transformation layer powered by dbt. These abstractions aggregate complex protocol interactions, such as automated market maker swaps, lending pool liquidations, and non-fungible token marketplace sales, into standardised multi-chain tables. Visualisation modules allow users to turn raw table outputs into line charts, bar plots, area graphs, counters, and pie visualisations, which can be grouped into composite shareable dashboards. Protocol builders can publish project pages that display real-time ecosystem health metrics to the broader market, while analysts can fork existing community code to modify underlying parameters without starting from scratch.

Pricing on Bitcoin.Tax operates on an annual tax-year model rather than an ongoing recurring execution charge. Users purchase access per tax year based on the total volume of transactions processed for that specific period. The platform provides a free tier covering up to 20 transactions, intended for basic filers or those evaluating the software's calculation flow prior to committing capital.

For active individuals, paid annual tiers expand transaction limits across standard brackets, including 500, 5,000, 10,000, and 50,000 transaction caps, with prices generally scaling from entry-level annual fees upward. Filers with very high trading volumes or algorithmic strategies can acquire enterprise or high-volume tiers tailored to hundreds of thousands of events. Each purchased tax-year license allows unlimited recalculations and report downloads for that specific tax period.

Professional preparers and CPAs can access multi-client licenses with dedicated dashboard tools. These institutional plans allow firms to purchase bulk transaction bundles, assign separate sub-accounts to individual clients, and manage permissions from a centralized workstation. Payment for plans can be settled using credit cards or major digital assets.

Dune uses a freemium model where users can sign up at zero initial cost to write public queries, build public dashboards, and explore community research. Free accounts receive a baseline allowance of monthly query execution credits, sufficient for casual exploration and standard research workloads. However, free accounts run on shared compute queues, which can lead to longer execution waiting times during peak network congestion, and all published work remains publicly visible.

For teams requiring dedicated resources, Dune provides paid commercial tiers, commonly structured around Plus and Premium subscriptions alongside custom Enterprise packages. Paid plans introduce private query authoring, private dashboards, larger allowances of monthly compute credits, prioritized query execution pipelines, and automated query scheduling. Furthermore, Dune offers programmatic API tiers priced according to monthly datapoint and execution unit allowances. Heavy data users consuming continuous streaming API responses or running resource-intensive historical aggregations must monitor their monthly credit burn rates closely, as additional compute units and private team seats scale total recurring costs.

Because Bitcoin.Tax is a non-custodial software service, it does not hold private keys, manage digital asset custody, or initiate transfer operations. The system interacts with exchanges strictly through read-only API credentials, which restrict access to historical balances and transaction records without permitting trading or asset withdrawals.

Account access is protected using standard industry security protocols, including two-factor authentication via time-based one-time password applications. User data, uploaded spreadsheets, and generated tax forms are stored within authenticated cloud environments protected by transport layer encryption and encrypted storage systems. Users maintain operational control over their stored datasets, with options to delete uploaded files, purge exchange sync histories, or wipe individual client portfolios at will.

While software-based data processing reduces custodial risks, users remain responsible for ensuring that API keys created on third-party exchanges have trading and withdrawal permissions permanently disabled. Additionally, filers must verify that uploaded CSV files do not contain extraneous personal identifying credentials beyond standard transaction parameters.

Dune is entirely non-custodial and read-only regarding asset management. The platform does not hold, transmit, custody, or manage cryptographic keys, wallet funds, or financial balances. Users connect to the analytics dashboard using standard email credentials or single sign-on mechanisms, with optional multi-factor authentication available to helps protect organizational accounts. Read-only wallet addresses can be queried publicly across raw ledger records, ensuring that no sensitive private keys are ever requested or stored on the platform servers.

From an organizational data security perspective, Dune supports role-based access management for corporate accounts and research teams. Workspace administrators can designate member permissions, control private dashboard visibility, and manage the generation and revocation of API keys. Network communications are secured through standard transport layer encryption protocols. Because public queries and schemas are accessible to all platform users by default, enterprise users managing proprietary trading strategies or unpublished commercial metrics must helps support their dashboards are explicitly set to private within paid team workspaces to prevent unintended strategy disclosure.

Bitcoin.Tax is accessible globally, serving taxpayers across multiple countries. The system natively accommodates calculation rules and currency valuations for the United States, Canada, the United Kingdom, Australia, and parts of Europe, allowing users to configure local base currencies and tax reporting frameworks suited to their home revenue authorities.

For United States filers, the software generates outputs formatted directly for IRS Form 8949 schedules, complete with attached descriptions, acquisition dates, disposal dates, cost-basis adjustments, and gain/loss totals. Data can also be exported into standard file formats ready for direct ingestion into common consumer tax preparation suites such as TurboTax and TaxAct, as well as comprehensive CSV dumps for custom tax software.

Customer support is primarily delivered through a digital ticketing framework, complemented by documentation guides, video walkthroughs, and FAQ archives explaining standard import formatting and troubleshooting. Professional-tier users receive prioritized inquiry handling to assist during peak annual filing deadlines.

Founded in Norway in 2018, Dune provides global web availability without traditional financial services licensing requirements, as it provides data analytics rather than investment execution or money transmission services. Access to the platform web portal and documentation is available internationally, subject to standard international sanction boundaries and acceptable use policies that prohibit malicious scraping or system abuse. Individual researchers and enterprise organisations can register accounts using standard email credentials or single sign on authentication without needing accredited investor verification.

Customer assistance is centered around an extensive public knowledge base, official platform documentation, and an active community Discord server. Free tier users primarily obtain assistance through community discussion channels and shared public forums, where experienced community analysts collaborate on SQL debugging and table mapping. Paid subscription tiers receive dedicated support routing, including direct technical assistance channels, higher service level agreements for enterprise accounts, and dedicated onboarding sessions for data engineering teams integrating Dune API streams into internal production data pipelines.

Selecting the right tier on Bitcoin.Tax depends primarily on trading volume, account complexity, and organizational role. Individual casual users with fewer than 20 total transactions across a tax year can utilize the complimentary free version to generate basic summaries without upfront software costs.

Active retail traders who execute frequent spot trades or participate in recurrent staking programs should calculate their total expected annual trade entries to select an appropriately sized standard tier. Upgrades can be performed mid-season if import volumes exceed initial estimates. For accounting practitioners, the multi-client Pro tier provides client isolation, white-label client summaries, and bulk billing capabilities that streamline practice workflows.

Selecting an appropriate Dune plan depends on workflow privacy, query execution frequency, and external pipeline requirements. Independent analysts conducting public market research and educational protocol breakdowns can operate comfortably on the free plan, leveraging the extensive community catalog. However, Web3 startups, risk advisory firms, and hedge funds typically require paid subscription tiers. These plans unlock private query workspaces to protect proprietary logic, eliminate watermarks on embeds, provide prioritized compute queues for complex nested queries, and supply dedicated API access keys to feed clean onchain metrics directly into custom internal applications and investor reporting decks.
