Every plan lists "Unlimited tax reports for all tax years", "Crypto and stocks coverage" and "Dividend tracking"; "Tax minimisation algorithm", "Tax loss harvesting", "Advanced reports" and "Audit report" start at Investor; "Trading stock report" is on Trader. Above the ladder: "We support up to one million transactions and offer custom solutions for high-volume traders." FAQ: "Our subscription pricing is per year not tax year, so with an annual subscription you can calculate your crypto taxes as far back as 2013." | "Summ has an annual subscription which covers all previous tax years." | "For access to reports, the tax loss harvest tool or chat and priority support, you will need to upgrade to the appropriate paid plan."

Three things, and the second is the one that costs money. (1) You buy on "Each tax report is a one-time purchase." (https://coinledger.io/pricing) and you contract on "Unless otherwise set forth on an applicable ordering document incorporating these Terms, the Services are billed in advance on a monthly basis and are non-refundable." plus "You shall retain access to such Paid Services from the time you cancel until the start of the next billing period, but you will not receive a refund or credit for any days remaining in your current billing period." and "Upon termination, CoinLedger reserves the right to delete all of your Content, data, and other information stored on CoinLedger’s servers." (https://coinledger.io/terms-conditions). Nothing in the Terms says a tax year you already paid for stays downloadable; section 3.3 goes further — "CoinLedger may also remove or delete your Content from the Services at any time in its sole discretion.". Export the Audit Trail and EOY Positions CSVs the day you file, because the audit trail "The Audit Trail is meant as a supplemental document for you or your tax professional's records. Once exported, it can't be uploaded or re-imported back into CoinLedger." (2) If you are a US user with a CoinLedger account opened before November 2025, your basis may not have migrated when you were told it had. https://help.coinledger.io/en/articles/10339065-how-can-i-download-a-snapshot-of-my-2025-cost-basis-reallocation-rev-proc-2024-28 (December 31, 2024) says "This reallocation process will happen automatically on Jan 1, 2025, and no further action is required by you to facilitate this process." while https://help.coinledger.io/en/articles/10309974-how-will-coinledger-support-new-per-wallet-cost-basis-tracking-rules-irs-rev-proc-2024-28 (December 18, 2025) says "If you are an existing user that used CoinLedger before 2026, you will need to opt-in to per wallet cost basis tracking to ensure that you are in compliance with the new IRS rules." Both are live on 2026-08-19. A user who read the first and did nothing spent all of tax year 2025 on universal basis, which by CoinLedger's own words "is no longer allowed to be used in the United States after Jan 1, 2025". (3) Non-US buyers should check the method before the form. Canada's own help page tells you to set the method by hand — "Be sure to also select Adjusted Cost Base (ACB) as your Report Calculation Method." — even though the methods page says the country selection governs; Germany is absent from the country-specific list entirely, so a German filer lands on the FIFO default, and https://coinledger.io/de sells "Built For Germany Tax Rules" while producing no German statutory form and using Australian phrasing ("We know that lodging your taxes can be stressful."). Anlage SO appears only in a blog guide as something you file yourself via Elster.

Three compounding surprises, all landing after the card is charged. (1) YOUR REPORTS ARE RENTED — THOUGH YOUR DATA IS NOT DELETED. Terms clause 5.2: "For recurring services, we grant you and your Authorised Users a right to access the relevant Services only for the duration that you continue to pay for the Service, subject to these Terms." The cancellation article is blunter: "Once your subscription expires, you will lose access to any paid features, including tax reports." Read the whole article, though, because the same page also says: "The data and integrations you have imported are retained and can still be reviewed on the Accounts and Transactions pages unless a refund is issued, which may result in their deletion." So the history stays visible; what dies is the ability to REGENERATE the filed report and to EXPORT anything. The documented escape hatch does not survive either: "Currently, the only way to back up your data in Summ (formerly Crypto Tax Calculator) is by exporting your Transaction report. This ensures you have a copy of your raw data outside the platform.", which requires an active subscription ("An active subscription is required to download reports for all years.") and whose nine columns carry no cost basis. Stop paying in year three and the 2025 return you already filed cannot be regenerated to defend an audit — even though you can still look at the transactions behind it. (2) AT $49 AND $99 YOU CANNOT CHANGE THE INVENTORY METHOD. The pricing page, fetched 2026-09-29, no longer names inventory methods by tier (the features that start at Investor ($249) are "Tax minimisation algorithm", "Tax loss harvesting", "Advanced reports" and "Audit report"), but the vendor's own pricing help article states the gate: "Additionally, tools like the Tax Loss Harvesting Tool, advanced inventory methods, and advanced reports are only available on Investor and Trader Plans." The US default is Highest In First Out, so a US filer on Rookie or Hobbyist is locked into HIFO — a method that materially changes the tax owed — and the fix costs $200 more rather than a settings click. (3) UK FILERS WITH DEFI FACE A ONE-WAY DOOR: "Please note that, currently, the Bridge and Swap categories are not supported if you choose HM Revenue and Customs as your inventory method. If you use other inventory methods (e.g., First In First Out or Average Cost), you can use these categories but will not be able to switch back to HM Revenue and Customs." The method that actually binds under UK law is unavailable to anyone who has bridged or swapped, and leaving it is irreversible. Worse, the escape is paywalled: "In Summ (formerly Crypto Tax Calculator), we provide three inventory methods if your country setting is the UK. The HM Revenue and Customs method is available for all paid subscriptions. We also provide the First In First Out and Average Cost inventory methods for users on the Investor and Trader plans." — so a UK filer on Rookie ($49) or Hobbyist ($99) has HMRC as their only method and therefore cannot use the Bridge or Swap categories at all. Lesser but real: the pricing page, fetched 2026-09-29, no longer lists smart contract transactions by tier, but the vendor's help centre puts them above the $49 tier: "Certain features, such as smart contract transactions, require a subscription to the Hobbyist Plan or higher."

Score dimensions

weights sum to 86

The published score is five dimensions, each weighted for the category. "Published criteria" is the criteria block above; the other four are the engine's own terms — availability, friction, trust record, measured data. Each bar is one side's points out of that dimension's maximum; the weight beside the name is its points of the 86-point weighted total. The published criteria above can fill 24 of the block’s 30. A weight marked “constant here” belongs to a dimension every ranked product in the category holds at the same value: it still counts in the total, and it orders nothing here.
