Core Capabilities of Our Tax Reporting API
Engineered for fintechs and crypto-native businesses, our API delivers the precision, automation, and auditability required to scale with confidence in any jurisdiction.
Real-Time Portfolio & Transaction Sync
Automatically ingest and normalize data from 500+ exchanges, wallets, and DeFi protocols. Maintain a single source of truth for all on-chain and off-chain activity with sub-5 minute latency.
Automated Cost Basis & Gain/Loss Calculation
Apply FIFO, LIFO, HIFO, or specific identification methods with full audit trails. Accurately handle complex scenarios like staking rewards, airdrops, and cross-chain transfers for precise tax liability.
Regulatory Form Generation & Filing
Generate country-specific tax forms (IRS Form 8949, Schedule D, international equivalents) ready for submission. Our logic is continuously updated for the latest guidance from global regulators.
Enterprise-Grade Security & Data Integrity
Built with SOC 2 Type II compliant infrastructure. All data is encrypted in transit and at rest. We provide immutable audit logs and role-based access controls for your compliance team.
Compliance Advisory & Audit Support
Access our team of crypto tax specialists for complex filing questions and audit defense. We provide detailed explanation reports for every calculation, simplifying communication with tax authorities.
Business Outcomes: Beyond Compliance
Our Compliance-First Tax Reporting API delivers more than just regulatory checks. It's a foundation for operational excellence, investor confidence, and sustainable growth in the digital asset economy.
Accelerated Fundraising & Due Diligence
Provide institutional-grade, auditable tax reports to investors and auditors in minutes, not weeks. Streamline capital raises and M&A by demonstrating robust, automated financial controls.
Operational Efficiency at Scale
Eliminate manual reconciliation and spreadsheet errors. Automate cost-basis tracking, income classification, and report generation for thousands of transactions, freeing your team to build.
Enhanced User Trust & Retention
Offer built-in, accurate tax summaries directly in your app's dashboard. This sticky feature reduces user churn and positions your platform as an essential financial hub, not just a trading interface.
Future-Proof Regulatory Agility
Our API dynamically adapts to new tax jurisdictions (e.g., EU's DAC8, MiCA) and reporting standards. Ensure continuous compliance without costly engineering re-writes or legal surprises.
Actionable Financial Intelligence
Transform raw blockchain data into structured insights. Identify top-performing assets, analyze user profitability, and generate data-driven reports for strategic business decisions.
Enterprise-Grade Security & Audit Trail
Every calculation is cryptographically verifiable and logged. Maintain a immutable audit trail for regulators and internal controls, built on SOC 2 Type II compliant infrastructure.
Build vs. Buy: The Compliance Tax API Decision
A detailed comparison of the time, cost, and risk involved in developing a compliant tax reporting system in-house versus leveraging Chainscore's production-ready API.
| Key Factor | Build In-House | Buy with Chainscore |
|---|---|---|
Time to Initial MVP | 6-12 months | 2-4 weeks |
Initial Development Cost | $250K - $600K+ | $0 (API usage) |
Ongoing Compliance Burden | Your team (1-2 FTEs) | Fully managed by Chainscore |
Coverage: Jurisdictions & Rules | Requires constant legal research | 100+ jurisdictions, auto-updated |
Security & Audit Readiness | High risk, requires separate audit | Pre-audited, SOC 2 Type II compliant |
Integration Complexity | High (multiple data sources, rule engines) | Low (single REST/Webhook API) |
Total Cost of Ownership (Year 1) | $400K - $800K+ | Starting at $50K |
Guaranteed Uptime & Support | Your responsibility | 99.9% SLA with 24/7 support |
Our Implementation Methodology
We deliver a structured, phased approach to integrate tax compliance into your product, minimizing disruption and accelerating your time-to-market.
Discovery & Architecture Review
We conduct a deep-dive analysis of your existing infrastructure and transaction flows to design a tailored integration strategy. This ensures our API aligns with your data models and business logic from day one.
Sandbox Integration & Testing
Develop and test against our full-featured sandbox environment using your anonymized production data. Validate transaction categorization, cost-basis calculations, and report generation before going live.
Security & Compliance Audit
Our security team performs a pre-launch audit of the integration, ensuring data handling meets SOC 2 Type II standards and that reporting logic complies with IRS, MiCA, and other relevant frameworks.
Production Deployment & Monitoring
We manage the cutover to live endpoints with zero downtime. Post-launch, we provide 24/7 monitoring, performance dashboards, and alerts for any data discrepancies or regulatory updates.
Ongoing Compliance Updates
We automatically update tax logic and reporting formats in response to new regulations (e.g., IRS Form 8949 changes, DAC8, MiCA). Your integration remains compliant without requiring code changes.
Dedicated Technical Support
Gain direct access to our engineering and tax specialist teams via dedicated Slack channel or ticketing system. We provide architectural guidance and troubleshooting to ensure operational excellence.
