Koinly vs Summ (Formerly Crypto Tax Calculator)

Koinly, founded in 2019, is a well-established crypto tax platform serving users in over 100 countries. It's known for its straightforward interface and solid exchange coverage, making it a popular choice for crypto investors with relatively simple portfolios.

Summ (formerly Crypto Tax Calculator), founded in 2018 – takes a more comprehensive approach to crypto taxation. As an official tax partner of Coinbase and MetaMask, Summ supports over 3,500 integrations and offers advanced features. It's designed to handle everything from simple trades to complex DeFi activities.

Let's break down how these platforms compare across the features that matter most.

Integrations (Supported Exchanges, Wallets and Blockchains)

The verdict: Summ's extensive integration coverage significantly reduces manual data entry and the risk of reporting errors.

Why it matters: Every unsupported integration means manual work or missing data. Summ's integration library is over 3x larger than Koinly's, which means you're far less likely to encounter an unsupported exchange or protocol.

DeFi Support

The verdict: If you're active in DeFi, Summ handles the complexity that often trips up Koinly users.

Why it matters: DeFi includes activities like staking your crypto to earn rewards, providing liquidity to trading pools, lending your assets, or using decentralized exchanges. These transactions are notoriously complex to track and categorize correctly for tax purposes.

If you've used platforms like Uniswap, Aave, Compound, or participated in liquidity pools, your tax software needs to handle:

• Cross-chain swaps (trading across different blockchains like Ethereum to Polygon)
• Liquidity pool deposits and withdrawals
• Yield farming rewards (income from DeFi protocols)
• Staking income (rewards from validating transactions)
• Lending and borrowing (interest earned and paid)

Koinly offers DeFi support, but users frequently report that complex transactions need manual review and correction. This is time-consuming and introduces the risk of errors.

Summ was built with DeFi at its core, supporting over 2,300 DeFi protocols with automatic categorization. The platform can identify and properly classify cross-chain swaps, liquidity pool transactions, and yield farming activities without manual intervention.

‍

Tax Reports & IRS Compliance

The verdict: Both platforms generate the necessary IRS forms. Why it matters: For US crypto investors, IRS compliance is non-negotiable. You need software that generates accurate, ready-to-file tax forms.

What is Form 8949? Form 8949 is the IRS form where you report individual crypto transactions and their gains or losses. Each trade, sale, or taxable event needs to be listed.

What is Schedule D? Schedule D summarizes your total capital gains and losses from all sources, including crypto.

Customer Support

The verdict: Both Koinly and Summ offer 24/7 human support, providing peace of mind that help is always available. 

Why it matters: When tax season arrives, and you're facing a deadline, responsive support matters.

Summ provides 24/7 live chat support that has been described as “outstanding,” “top notch,” and “excellent”. We made it our mission to offer real human support for all our customers, regardless of plan tier, so that troubleshooting an issue is just that bit less stressful for everyone. 

Security

 The verdict: If security is your priority, Summ offers protection that Koinly doesn't match.

Why it matters: Crypto tax software accesses your complete financial history across all exchanges and wallets. This is sensitive data that deserves serious protection.

What is SOC 2 Type 2? It's an independent audit that verifies a company's security practices meet rigorous industry standards. It's the gold standard for SaaS security compliance.

While Koinly is SOC 2 certified, Summ goes the extra mile with multi-factor authentication and zero-trust architecture (assuming no user or system is inherently trustworthy).

Pricing

The verdict: Both platforms have similar entry-level pricing. Summ offers better value for high-volume traders (10,000+ transactions) and includes more features at every tier.

Why it matters: While entry-level pricing is comparable, the value equation shifts when you consider what's included. At the same $49 starting price, Summ provides 3x more integrations and additional security measures – features Koinly doesn't match.

Annual subscriptions: Both prices reflect annual subscriptions that cover historical tax years. For Summ, you pay once and can generate reports for any previous year back to 2014, which can be valuable if you need to amend or submit past returns. On the other hand, Koinly requires you to buy a separate plan for every year you want to generate reports for. 

Money-back guarantee: Both Summ and Koinly offer a 7-day refund upon approval.

Free Tier

The verdict: Summ's free tier is significantly more generous.

Why it matters: Before signing up to any new platform, it's important to be able to conduct a full evaluation so you don't get locked into a product that's not 100% right for you. 

Both platforms offer free tiers, but with different limitations:

Summ Free Tier:

• Portfolio tracking for 500,000+transactions
• Unlimited integrations
• Smart suggestions and auto-categorization
• DeFi and NFT support
• Tax reports require a paid upgrade
• Free mobile app for portfolio tracking on iOS

Koinly Free Tier:

• Portfolio tracking for only up to 10,000 transactions
• Limited features
• Tax reports require paid upgrade

NFT Support

The verdict: Both platforms handle NFT taxation, with Summ offering broader cross-chain coverage.

Why it matters: NFTs (non-fungible tokens) create unique tax situations. Whether you're buying, selling, or creating NFTs, each transaction has specific tax implications. The cost basis tracking for NFTs can be particularly tricky, especially if you've traded across multiple marketplaces.

Both Summ and Koinly support NFT transactions, including major marketplaces like OpenSea. However, Summ's broader blockchain coverage means better support for NFTs across various chains, not just Ethereum.

Tax Loss Harvesting

The verdict: Both platforms support tax loss harvesting for qualifying plans. Koinly offers the feature on all tiers, whereas Summ only offers it for Investor and Trader plans. 

Why it matters: Tax loss harvesting is a strategy where you sell assets at a loss to offset capital gains, reducing your overall tax bill. Done correctly, it can save you significant money but you need software that identifies these opportunities.

Both Summ and Koinly offer tax loss harvesting features. On Summ, this tool is available for Investor and Trader plan subscribers, helping you identify unrealized losses you could harvest before year-end.

Conclusion: Why Summ is the Best Koinly Alternative

After comparing the platforms across integrations, DeFi support, security, pricing, and customer support, Summ emerges as the strongest Koinly alternative for most US crypto investors.

Here's what sets Summ apart:

• 3x more integrations (3,500+ vs 1000+) means less manual work
• More features at comparable pricing – smart auto-categorization and additional security included
• Comprehensive DeFi support with 2,300+ protocols
• 24/7 human support when you need help

However, if you need to pay with cryptocurrency, a feature Summ doesn't currently offer then Koinly may be the best option for you. Koinly also has a straightforward interface that works well for simpler portfolios.

If you're a US investor with any DeFi activity, multiple exchanges, or security concerns, Summ delivers more value for the same investment.
