    Date: Apr 21 2026
    Summary

    Overall i'm back for my second year, and hopefully my third year next year. I hope they offer a promo code or something.

    Positive

    Nice website, lots of options and advanced features, high transaction count for paid accounts. Supports all the wallets.

    Negative

    Support is good but slow to respond, this is mainly for advanced users who have hours to spend correcting transactions, unless you didn't do many transaction in your tax year.

    Worked very well the first year, tougher the next but likely due to my trading complexity

    Date: Apr 27 2026
    Summary

    For all my portfolio stuff, this is a wonderful platform.

    For leveraged/trading, it works, but not as user friendly. It could be some settings that need to be tweaked, but my trading wallets had shown the wrong balances. I would have had to go into each transaction to make manual changes. It's possible that the trading platform I used reported items like "Hit TP", "Hit SL" differently or in a way that's not easily translatable to the platform. As such, I left 4 stars.

    Also, the AI bot support chat thing was exceptional. It was able to process a refund on a subscription I forgot about!

    Above average and is more than enough for the average investor. Thank you SUMM!

    Positive

    Aesthetically pleasing platform
    Discount via Coinbase
    Caught things I had missed
    Easy to make changes
    AI Bot Support Chat very good!

    Negative

    No advanced subscription renewal notice
    Solana trading/perpetuals, the balances did not show accurately. Showed all wallets at the wrong balances, when there's profits/losses from leveraged trading in there.

    Issue importing file into MEXC

    Date: Apr 21 2026
    Summary

    Overall, this is a complex environment with some many exchanges and wallets to deal with. I am satisfied with SUMM. Always prompt support

    Positive

    Very quick response and came up with the solution. Gilbert worked through the files I uploaded and advised to remove two columns, UID and MEMO.

    Negative

    It looks like SUMM had not updated their rules to accept MEXC downloads of withdraw transactions. Got there in the end

    Very good product.

    Date: Apr 28 2026
    Summary

    Excellent.

    Nothing has ever gone wrong for me with this tool.
    It's done exactly as I've wanted it to as a crypto trading hobbyist.
    If I scaled up my business endeavours to professional trading, I would still use this tool. It's that reliable.
    I'd just need to upgrade my yearly subscription and it would be "plug and play" so to speak.

    Positive

    Everything feels modular and interconnected.
    There is a high-quality customer support bot and human assistance where it's needed.
    The calculations are accurate and the tool corrects errors that I had no clue about.
    I completely trust this tool because it's earned it, through good results and quality, especially for the price.
    This tool has a massive range of support and integrates well with other tools like TurboTax!

    Negative

    I noticed that one article, specifically about importing into TurboTax, was not kept up-to-date and so I had to figure out a big problem myself when the article could've took hours off of my workload.

    I found the same with overly optimistic sync time estimates.
    The tool read that sync could take as long as 5 minutes.

    It took probably about an hour or longer for a few accounts, presumably because the service is very busy during the end of tax season.

    I spent a long time troubleshooting but if I knew that it would just take more time, that would have cut down a lot of my workload.
    But, because of the excessively optimistic time estimate, I thought there was a bug and wasted twice or three times the amount being stumped and getting frustrated on what's going wrong.

    Helps a lot with crypto tax!

    Date: Apr 26 2026
    Summary

    Overall Summ is a good product with many great features that will help anyone make sense of their crypto every year.

    Positive

    Summ is easy and intuitive to use. It is easy to important all transactions from multiple platforms for analysis. It includes convenient summary pages and breakdown of complicated crypto categories into a simple format.

    Negative

    Summ didn’t send an email to remind me of my upcoming annual payment, but the automated message system helped to address my concern.

    Intuitive design and helpful team

    Date: Mar 16 2022
    Summary

    I was impressed with the responsive customer service of CryptoTaxCalculator, at least I found it much faster and helpful than that of Coinbase at their start (though different level of service).

    Positive

    Easy to understand and navigate through the pages and data,
    flexible to monitor and correct any transaction discrepancy,
    above all, responsive team to all my inquiries.

    Negative

    Will provide more constructive feedback as soon as I file my first crypto tax report at CRA.
    Thank you to the team at CryptoTaxCalculator.

    Date: Dec 11 2021
    Summary

    Happy with the service and will stick with them! Tax time can be daunting and can be difficult to remember past years transactions, especially when having to start from scratch. Im happy with the team as I got a result when I thought it would never get resolved with the many challenges.

    Positive

    Customer Service, especially David who was able to provide a single point of contact and answer all my questions! Appreciate the support through my difficult taxes.

    Negative

    The challenges were mainly to do with the reports from my exchanges and not all the data is provided in the reports.

    So far so good!

    Date: Dec 16 2021
    Summary

    Being new to crypto tax, so far i'm very pleased with this service. I hope they add NFT's in the future. so far so good!
    not your keys, not your coins. DRS this platform helps keep track of all your trades once you enter them via API or CSV. So make sure to keep a log all your trades!

    Positive

    This service has many features, one including adding wallets that are not listed, but being able to relabel them from a CSV file.
    Helpful customer service.
    Trade cost basis breakdown on each trade.
    Free trial without adding CC details is a huge pro!

    Negative

    It can get confusing for new crypto users however once you understand how and what you need to be taxed on, relives many headaches!

    Inability to import wallet addresses that are on the ETH blockchain that are not supported directly on crypto tax software, however you can relabel/link the address that is listed as the receiving address from an exchange or supported wallet to a CSV file that you imported so cost basis and stuff update to that address. click on the 3 dots on the right of the transfer in question and click edit, then scroll to the bottom of the listed wallets and at the bottom will be your imported wallet you want to link/label as!

    Slightly for more for advanced users.
    I don't believe they support NFT's.

    A few things notably missing, but the best I've found after trying 5 others

    Date: Dec 20 2021
    Summary

    Although there are a few shortcomings, it is extremely complicated to nail crypto and I feel they're on a better track than anyone. I haven't regretted the yearly sub.

    Support - a mixed bag. Typically it'll take two days, but David is excellent - the rare type that closely reads and understands questions and gives excellent, precise answers. The experience with Patrick wasn't good though when I was trying to find where to enter current prices for unsupported tokens - Patrick not understanding my desire to see unrealised gains and have a substantial part of the main page - the dashboard - relatively accurate.

    CTC is good already, and I think it'll only get better, so do highly recommend.

    Positive

    CTC was the app I went ahead and paid for after trialling Koinly, CoinTracker, Crypto.com, Rotki, and Kubera.

    I was particularly interested in how well it handled trickier transactions, IDO's, staking rewards and exchange support. So far it does better than the rest, in particular Koinly - it's main competition for Australia. IMO Koinly gets one or two tax issues incorrect, but CTC gets them right.

    CRC is well laid out too - lots of info on the page for a glance rather than Koinly's more clicks approarch. Kubera was a beautiful design but isn't crypto specific - and no generalised program is going to handle crypto well.

    Wallet/Exchange pretty good, nicely organised and configured, but syncing about 7/10. Some major companies like Gate.io (#9 on CMC) and Celsius have APIs but can only be imported via CSV which is a pain. MEXC (#25) not supported and its CSV incompatible so bit of mucking around there. And I get the rare transactions on BSC not coming through - but a hard sync gets them perfectly.

    Negative

    1. Desperately needs the ability to enter a current price for currently held assets that it can't fetch prices for. I'd rather a token's worth using a price I haven't updated for a week, just like transactions I haven't imported for a week, that in showing the tokens worth $0. It makes the main page pretty worthless - Overall Balance, Unrealised Gains (overall and for each unsupported coin), and Winners and Losers simply can not be accurate without this. Sharesight, my share tracker, allows manual entry of current prices.

    2. I really can't use the reports directly as the CGT methods only have LIFO, FIFO and HIFO, with one method applying to the whole portfolio. What I'm missing is the additional "Minimise CGT", "Minimise gain" and "Maximise gain" options, and on a per asset per year basis that Sharesight allows. But the reports still help out a ton - it would be impossible without it.

    3. Pricing - tricky one. I'll likely need the top Day Trader tier soon despite not being anything like a day trader - a few buys per week max and I rarely sell. It's all these silly staking rewards of mere dollars I get daily which I wish Binance and the like would just credit me weekly. Or buying a token with low liquidity can sometimes result in something like 20 transactions at all the different prices the order was filled at. Not CTC's fault, it's DB space nonetheless and each has to be tracked separately for CGT (and additionally income for staking rewards), but just know transactions can really up quickly.

    Crypto tax calculator

    Date: Nov 29 2021
    Summary

    Excellent product, with all the other programmes I have used the results were full of errors, the CGT calls were wildly out.

    Positive

    The product works it’s easy to import files from kraken, ledger and Trezor ; 2 years CGT done in 40 mins, well done. This is the first product I have found which is not full of bugs and the CGT is accurate.

    Negative

    Nothing so far, I have not found any issues when using the software.
