The response was quick, which is rare in tax and financial services companies. The conversation was smooth, and they handled my issue well.
I was worried about managing transactions across multiple wallets and exchanges, from CEXs to Solana and Base. KoinX brought all the data into one place and made the process much easier. It also reduced a lot of work for my CA, especially for transactions and trading pairs that were hard to understand because they were in USD.
Really happy with the service. Everything was handled quickly and clearly. I’ll definitely be using their services again in the future.
KoinX team is responsive and knowledgeable about tax regulations. They also follow up properly and investigate any differences in starting and ending balances or profit and loss figures, either correcting them or clearly explaining the reason. I used KoinX with Bitget and had a good experience.
Very helpful service. I bought the plan for my crypto tax report and received it within minutes. The team was also very supportive and helpful with the tax filing process.
Had a really good experience with KoinX. The tax report was easy to generate, and whenever I had an issue, the support team responded quickly and sorted it out. Their customer service is excellent and makes the whole process much smoother.
It was the last day to file my ITR, and I had no idea how I would get it done in such a short time. KoinX really came through and completed the entire process in nearly 2 hours, helping me file on time and avoid the late filing fee. Really happy with the service.
This is my second year using KoinX, and the experience has been great both times. The team explained the tax calculations clearly and also suggested ways I could plan better for taxes next year. Really happy with the overall service. Special thanks to Arjun and Khushi for all their support.
Before KoinX, handling crypto clients involved a lot of back-and-forth, missing CSVs, transaction issues, and hours spent fixing mismatches. At one point, I even considered avoiding crypto cases altogether. KoinX has made the entire process much easier for both me and my team.
The reports are clear, easy to understand, and simple to explain to clients. Managing multiple crypto clients from one dashboard saves a lot of time, and generating reports is quick and smooth. KoinX has made crypto tax filing much easier for me as a CA.
Yes, it's crucial to report all crypto transactions. The IRS requires detailed records, including dates, amounts, and counterparties involved. Using KoinX, you can simplify this process, helping you generate accurate reports effortlessly.
Yes, crypto-to-crypto trades are taxable. For example, if you exchange Bitcoin for Ethereum, the Internal Revenue Service (IRS) and tax authorities will count it as the sale of Bitcoin at the market price. Each trade should be reported, and you may incur capital gains or losses based on the cryptocurrencies' value.
Cryptocurrency exchanges issue a 1099 form to any customers who earn more than $10 in interest throughout a financial year. Reporting this income to the IRS to maintain compliance accurately is essential.
Yes, all crypto transactions, including those with international exchanges, must be reported to the IRS.
Crypto tax rates in the US depend on income and holding period. Short-term gains are taxed at ordinary income rates of 10-37%. Long-term gains are subject to preferential rates of 0-20% based on income. Crypto received as income is subject to regular income tax rates.
While there’s no legal way to avoid crypto taxes, strategies like tax-loss harvesting can help you save a few dollars on your tax bill.
From Filing-ready reports to multi-client management, KoinX helps your practice handle crypto tax end to end.
