Tax tools.
1099-DA, white-label, API.
Kryptos gives exchanges and custodians the compliance tooling they need to satisfy regulators and the user-facing tax features that reduce support tickets and churn. Deploy via API or white-label in weeks, not quarters.
Trusted by retail exchanges, institutional custodians, brokers, and neobanks adding crypto.
Every compliance and user tax tool in one platform.
From IRS broker reporting to in-app tax calculators, Kryptos gives you the full stack so you are not building it from scratch or stitching together vendors.
Embedded tax tools
Drop a tax center directly into your exchange or custodian UI. Users see their gains, losses, and downloadable tax reports without leaving your platform. White-label branding throughout.
1099-DA broker reporting
IRS Form 1099-DA requires brokers, including crypto exchanges, to report customer basis and proceeds. Kryptos handles collection, calculation, and e-file submission so your compliance team is not building this from zero.
User tax calculation
Per-user gain/loss calculations with support for FIFO, LIFO, HIFO, and specific identification. Users can download reports for their jurisdiction without contacting support.
Regulatory compliance
DAC7 reporting for EU exchanges, OECD Crypto-Asset Reporting Framework (CARF) filings, and FinCEN requirements. One integration covers your obligations across multiple jurisdictions.
API-first integration
REST API and webhooks for real-time transaction streaming, tax event notification, and report generation. SDKs in TypeScript and Python. Most integrations go live within four weeks.
White-label deployment
Your brand, your domain, your user experience. Kryptos powers the calculation and compliance engine under the hood while your users never see our name. Custom styling via design tokens.
Typically live within four to six weeks from contract signature.
Every type of crypto financial institution.
Retail exchanges
Give your users a tax centre they will actually use. Reduce the support tickets asking 'how do I do my taxes?' and the churn that happens every April when users realise they have no idea what they owe.
Institutional custodians
Provide institutional clients with the cost-basis tracking and reporting they need for their own fund accounting. Reduces friction at audit time and differentiates your custody offering.
Regulated brokers
Meet your 1099-DA obligations without building the entire broker reporting stack yourself. Kryptos integrates with your existing transaction records and handles the IRS filing workflow.
Neobanks adding crypto
Launch crypto with compliant tax tooling from day one. Your users expect the same tax visibility for crypto that they get for stocks. Kryptos gives you that without a separate engineering project.
Common questions from compliance and product teams.
How does 1099-DA broker reporting work?
Under IRS regulations effective for 2025 transactions, crypto exchanges classified as brokers must report each customer's proceeds and cost basis on Form 1099-DA. Kryptos connects to your transaction database, calculates the required fields using IRS-compliant methods, generates the forms, and submits them via the IRS FIRE system or your preferred filing agent.
How long does the API integration take?
Most clients are live within four to six weeks from contract signature. The timeline depends primarily on how normalised your transaction data is. If you have a clean event-log API, we can typically connect, validate, and go live faster. We provide dedicated integration support throughout.
What white-labeling options are available?
Full white-label is available for Enterprise plans. Your users see your logo, your domain, and your color scheme. We also offer a co-branded option where Kryptos branding appears alongside yours. Both options include custom email templates for tax report delivery.
Can users choose their own cost-basis method?
Yes. FIFO, LIFO, HIFO, and specific identification are all supported. For US users, IRS-default FIFO is the baseline, but users can elect a different method where permitted. The method election is stored per-user and applied consistently across all their transactions on your platform.
How do you handle DAC7 and OECD CARF for non-US exchanges?
DAC7 (EU platform reporting) requires exchanges to report seller information to member state tax authorities annually. OECD CARF extends similar requirements globally. Kryptos collects the required data fields during onboarding, maintains them throughout the year, and generates the XML filings in the required schema for each jurisdiction you operate in.
The rest of your obligations, one platform.
Reporting is one job. The same account and transaction data covers global filing and US rules, through a single integration.
