FinTax Review 2026: Crypto Tax Software for TON Users

FinTax is crypto asset financial and tax management software. Its social profile calls it a crypto accounting and tax fintech company. A launch write-up links it to TaxDAO, a Web3 finance and tax consultancy, and says it was founded by the former tax director of Bitmain.

In mid-2024 the team launched a Telegram mini-app that extends the software to mobile devices. It is described as the first professional crypto tax filing tool aimed at TON users. A search snippet from the project's Chinese-language social account also mentions a seed funding round at a $40 million post-money valuation, with YZi Labs' EASY Residency program named as the lead. Terms of that round are not otherwise published.

The website at the listed address currently shows a sealed HashiCorp Vault login screen. That is a secrets-management page, not a product page, so the working product is best found through the Telegram mini-app. Pricing, audits and supported jurisdictions are not published.

Crypto tax software collects a user's transaction history, classifies each event (trades, transfers, income), calculates gains and losses under a chosen method, and produces reports or forms. FinTax follows this model, according to a launch write-up of its Telegram mini-app.

The mini-app is said to connect with TON wallets and sync wallet data automatically, then generate tax forms from the imported transactions. It lives inside Telegram, so users reach it from their phone without a separate website login.

The tax treatment applied, the supported jurisdictions and the transaction sources beyond TON are not published in the material reviewed.

FinTax does not publish pricing in the material reviewed. A launch write-up says payment is handled through TON Wallet and possibly Telegram Stars, but no amounts, plans or free tiers are given.

Users would likely see the actual cost inside the Telegram mini-app or at checkout. Confirm it there before importing data.

No audits, security certifications or custody details are published for FinTax. Tax software of this type usually reads wallet and transaction data rather than holding funds. Even so, users should connect only the wallets and data needed, and check what permissions the app requests.

The main website currently shows a sealed secrets vault, which is internal infrastructure and says nothing about the product's safety. A launch write-up says the mini-app does not collect personal details from Telegram accounts, but this is a single-source claim and no privacy policy was reviewed. No incidents or regulatory actions appear in the material reviewed.

Tax outputs from any software should be checked against local rules. Regulatory treatment of crypto differs by country, and FinTax does not publish which jurisdictions it supports.

FinTax is aimed at crypto holders who use TON wallets and Telegram and want help organising transactions and preparing tax forms. It may also suit people who prefer a mobile-first tool to desktop tax software. Users in jurisdictions with complex crypto tax rules should confirm support first and consider consulting a tax professional.
