The Problem

You're paying too much in crypto tax, and you don't even know it.

Cryptocurrency is a complex new asset class, and most CPA firms aren't equipped to account for it properly.

Your CPA missed DeFi, staking, and airdrops.

Many generalist CPAs treat crypto like stocks, which can lead to missed reporting requirements, incorrect cost basis, and suboptimal tax outcomes.

The IRS is asking about your crypto.

You may be receiving Form 1040 questions, CP2000 notices, or Letters 6173 and 6174. The IRS is claiming you owe tax. We know how to respond to resolve these issues and minimize what you owe.

Your cost basis is wrong. You're overpaying.

Lots are mismatched, transfers are double-counted, exchanges report incomplete data. We reconcile every transaction and deliver an audit-ready history.

Real Results

Numbers we've put
back in clients' pockets.

Anonymized examples from real client engagements. Past results don't guarantee future outcomes, but they show what specialized tax strategy can deliver.

IRS Defense

$47K notice reduced to $3.2K

Client received a CP2000 from the IRS for $47K in unreported crypto gains. We rebuilt the cost basis from on-chain data and cut the assessment 93%.

Theft Loss Deduction

$1.4M tax deduction substantiated from scam loss

A client lost $1.4M in a pig-butchering scam. We prepared a comprehensive tax memorandum documenting the transactions, facts, and applicable IRS guidance to support a theft loss deduction.

Entity Structuring

$23K saved annually

Self-employed contract worker was set up as a sole proprietor. We established an S-Corp with $60K reasonable salary, saving $23K/year in self-employment and related tax.

Reconciliation

$61K in phantom gains removed

Seven years of unreconciled trading across 11 exchanges and 40 wallets. Reconstruction identified $61K in overstated gains, saving $16K in taxes.

Tax-Loss Harvesting

$83K in losses harvested

During the end of 2025, systematic loss harvesting captured $83K in realized losses, saving $33K in taxes in the current filing year.

Estimated Payments

$4,200 in penalties avoided

DeFi investor had been paying only at filing time. Quarterly safe-harbor planning eliminated $4,200/year in underpayment penalties.

Client Voices

Trusted by serious crypto investors.

Garrett actually picks up the phone when I call. After three years with a generalist CPA who ignored my DeFi positions, working with COS Elite was a complete reset. Saved me five figures the first year alone.
