BasisGuard - Explainable Crypto Tax Reports

Crypto taxes that show their work

For
Crypto investors with multi-year histories across many exchanges and wallets, including DeFi users and multi-entity filers, anywhere tax reports are required
Who are
Frustrated by missing cost basis, duplicated or omitted records, DeFi and margin trades that get misclassified and inflate gains, and support that is AI-only when the numbers are wrong
We build
A crypto tax app that imports from 100+ wallets and exchanges, automatically detects and repairs missing cost basis and misclassified transactions, explains how every gain was computed, and generates country-specific tax reports on demand
Unlike
CoinTracker, which reviewers say misclassifies margin trades, gives generic support replies and gates tax forms behind a $1,999 plan
Koinly, which still needs significant manual editing for DeFi and puts users behind an AI chatbot
CoinLedger, whose reconciliation reviewers call challenging and whose Done For You service is expensive
We deliver
Automatic flagging of missing cost basis and suspect transactions before the user files
A per-transaction audit trail that shows why each gain was calculated
Guaranteed human escalation for calculation issues during tax season
So that
Crypto investors can file accurate, defensible tax reports in hours instead of paying accountants thousands of dollars or spending weekends manually editing transactions
Revenue potential
$40K MRR
Build time
4-6 months for an MVP covering the top 30 exchanges and 3 tax jurisdictions
Target market
Individual crypto investors worldwide, especially those with multi-year, multi-exchange and wallet histories, DeFi activity and missing cost basis. A secondary segment is multi-entity users (personal, SMSF, company) and the accountants who serve them.

The Problem

Crypto investors with years of activity across several exchanges and wallets end up with missing cost basis, duplicates and omissions, and say "I had 5 or 6 exchanges and 3 years to reconcile. It stressed me out to think about it." Even with software, DeFi and margin trades get misclassified and inflate gains, and support is AI-only when the numbers are wrong.

“Just recently, I found out that I needed to be filing taxes on these transactions. Like most people, I freaked out. I called many different "crypto accountants" who wanted THOUSANDS of dollars to help me file Form 8949 from my past few years.”

“because of the " Missing Cost Basis" that the crypto exchanges does not calculate for the customers.”

“Bitget margin transactions are being classified as loan repayments and generating very large capital gains, while other transactions have missing or zero cost basis, which is also significantly inflating my gains.”

“It has gotten better identifying defi trades but still requires significant manual editing.”

“It took a while to become familiar with the program, but even then, I wasn't always sure when corrections were necessary or how to make them.”

“I’m paying hundreds of dollars to use an app that isn’t working and would take someone a very small amount of time to fix, but instead I can’t get any more work done on my taxes due to them not wanting to provide any support.”

“They have an AI chatbot who has clearly been given the mission of avoiding connecting with a human.”

“CoinTracker is asking me to upgrade to a $1,999 plan to obtain the tax forms, while I still cannot get meaningful help correcting the underlying transactions that those tax forms would be based on.”

“managing three separate sign-ins and paying full price for each is frustrating.”
