Takuya Tanabe
Cointax Inc.cryptact is more accurate in its calculations than any other service, and the data it outputs is easy to verify.
Calculating P&L on crypto trades is extremely complex, especially if you use several exchanges, trade on overseas exchanges, use different currencies (yen, dollars and so on) or swap one crypto for another. cryptact converts everything to Japanese yen automatically from your transaction history using price data fetched every minute, so there is no need to convert to yen yourself and no worry that the result drifts far from your actual trades.
I have used it since launch, and the supported exchanges, currencies and usability keep improving, so it gets easier to use every day.
Some parts of crypto P&L calculation are hard to handle on your own, but cryptact calculates following the National Tax Agency's guidelines and flags odd transactions as errors, so mistakes are unlikely. I highly recommend it.
Yuichi Murakami
Certified Public Accountant OfficeJust connect a wallet address to easily import DeFi transaction data, and with automatic identification it's easy to use even for frequent traders.
cryptact not only supports many exchanges in Japan and abroad automatically, it can also import transaction history from many of them via API, and it collects market prices for a very large number of crypto assets automatically.
For anyone who used to gather and calculate information in a different format for each exchange, it should greatly reduce the effort of collecting and applying transaction history and market prices.
DeFi and NFT trading, a market growing every day, can also be imported just by connecting a wallet address, and with automatic identification it feels very easy to use for frequent traders. If you upload your transaction history regularly, it also becomes easy to understand your asset position and plan how to manage it toward the end of the year.
Crypto taxes:
do you have these misconceptions?
My annual P&L on the exchange is under ¥200,000,
so I don't need to file a tax return
The P&L shown on an exchange can differ from your P&L for tax purposes.
I only swapped crypto for crypto and never converted to yen, so I made no profit
Even if your yen balance didn't change, swaps between crypto assets count toward your profit calculation.
I invested only a small amount,
so I don't need to calculate P&L
As a rule, P&L is calculated with the total average cost method, so it often differs from what you expect.*
*For individuals in Japan
cryptact, also used by tax accountants, supports the total average cost methodso you can file your tax return with confidence
Individuals in Japan are, as a rule, required to calculate with the total average cost method.
With this method you often turn out to have a profit even when you feel you've made a loss.
Question
What is the P&L?
*Trades within the same year *Calculated per 1 coin bought/sold *Using the total average cost method
Buy crypto for ¥1.5 million
Sell for ¥1.4 million
Buy for ¥900,000
A profit of ¥200K
First, find the average purchase price for the year
(¥1.5M × 1) + (¥0.9M × 1) = ¥2.4M
¥2.4M ÷ 2 coins = ¥1.2M
Subtract the average purchase price from the sale price
¥1.4M - ¥1.2M = ¥0.2M
