Coinfig turns exchange, wallet and CSV history into clear, defensible tax figures for your IRS return. Your tax report is free for up to 100 transactions, with a completeness check before you ever rely on the numbers.
See a sample reportCoinfig reads your history straight from the origin: direct exchange API connections and our own full archival blockchain nodes. Nothing is inferred from a third-party indexer, so the figures trace back to ground truth.
Direct, read-only API connections to the venues you actually use, local and global, plus a universal CSV importer for everything else.
On-chain wallet coverage from our own full archival nodes. Every historical balance and transfer is verifiable down to the block.
Most tools calculate. Coinfig also tells you whether the calculation is built on complete data. The Data Completeness Score grades your year from 0 to 100 and gates the report, so you never file on a guess.
What came in vs. what went out per asset, value-weighted so a R1 gap doesn't tank a clean year.
Deposits and withdrawals matched across your exchanges and wallets; anything unmatched is listed for you to fix.
The score gates your report, so you never file on a guess.
Missing sources, unmatched transfers and unexplained outflows flagged before they reach a report.

Coinfig turns your exchange and wallet history into clear capital gains and income figures for the US calendar tax year. It works out proceeds, cost basis and net gain on every disposal, and separates short-term from long-term based on how long you held each lot.
You get downloadable, transaction-level schedules and workings that support your filing, including the capital gains figures reported on Form 8949 and Schedule D. Coinfig is a calculation and reporting tool, not tax advice, and it does not imply any endorsement by the IRS.
US tax rules separate crypto held for one year or less (short-term) from crypto held longer than one year (long-term). Short-term gains are generally taxed at ordinary income rates, and long-term gains at lower rates.
Coinfig tracks the holding period of every lot and reports your disposals split into short-term and long-term, so the figures line up with how the IRS treats them. Your actual rates depend on your income and personal circumstances.
Coinfig calculates cost basis lot by lot, so every disposal traces back to the specific units you acquired and the price you paid, with the full working shown behind each figure.
From 2025 the IRS expects cost basis to be tracked on a per-wallet or per-account basis. How that applies to your own history is worth reviewing with a tax professional, and Coinfig shows its assumptions clearly so you can check them.
Yes. Crypto received as income, for example from staking rewards, mining, airdrops or payment for work, is generally taxable at its fair market value on the day you receive it.
Coinfig records these as income events and values them at the time of receipt, kept separate from the capital gains on any later disposal. For how a specific reward should be treated, check with a tax professional.
Yes. When you connect an exchange through its API, Coinfig uses read-only access to import your transaction history. It cannot place trades or move funds.
If you prefer not to share an API key, you can also import your history by CSV from most exchanges.
Coinfig supports direct read-only integrations with selected exchanges and universal CSV imports for most exchanges that provide downloadable trading history.
If you use a US exchange with a non-standard export format, support can confirm the fastest way to bring your history in.
No. Coinfig provides calculations and reports based on the data you import and the settings you choose. It does not provide personalised tax advice, and it does not imply any endorsement or approval by the IRS.
For complex situations, such as business trading, mining, or unusual transactions, consult a qualified tax professional. You remain responsible for what you file.
