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.

Yes. KoinX provides tax optimization insights that help US investors identify unrealised losses across their portfolio. These insights help you spot assets that could be disposed of before the tax year ends to offset capital gains. Since the IRS allows crypto losses to offset gains from other assets with no annual cap, this can meaningfully reduce your federal tax bill.
The IRS classifies cryptocurrency as property under IRS Notice 2014-21, not as currency. This means every sale, trade, or spending of crypto is a taxable disposal subject to capital gains tax. Crypto received through mining, staking, airdrops, or as salary is taxed as ordinary income at your applicable federal income tax rate on the day of receipt.
Short-term capital gains apply to crypto held for 12 months or less and are taxed at ordinary income rates ranging from 10% to 37%. Long-term capital gains apply to crypto held for more than 12 months and are taxed at reduced rates of 0%, 15%, or 20%, depending on your total income for the year.
Yes. The IRS taxes NFTs under the same rules that apply to other crypto assets. Buying an NFT with cryptocurrency is a taxable disposal of the crypto used. Selling or trading an NFT triggers capital gains tax on any profit. Some NFTs may qualify as collectibles, attracting a higher long-term capital gains rate of up to 28%.
Several IRS-compliant strategies can reduce your crypto tax liability. Holding assets for more than 12 months qualifies you for lower long-term capital gains rates. Selling crypto at a loss can offset your capital gains and reduce up to $3,000 of your taxable income each year. Donating crypto to a qualified 501(c)(3) charity is fully tax-deductible at the asset's fair market value on the donation date.
Yes. The IRS allows crypto losses to offset capital gains from any asset with no annual limit on the amount. If total capital losses exceed your gains for the year, you can deduct up to $3,000 of the remaining loss against your ordinary income. Any unused losses beyond that amount carry forward to future tax years until fully used.
US taxpayers must report crypto disposals on Form 8949 and summarise totals on Schedule D. Crypto income from staking, airdrops, or freelance payments is reported on Schedule 1 or Schedule C, depending on whether it is business income. All taxpayers must also answer the digital asset question on Form 1040, even if no taxable crypto activity occurred during the year.
No more spreadsheets. Just clean, IRS ready reports in minutes.
