Best Koinly alternative in the UK? Finbooks vs Koinly

For UK investors who need to report both crypto and traditional investments, Finbooks is the better Koinly alternative. Koinly calculates crypto gains and income only, while Finbooks brings crypto, shares, ETFs, bonds, derivatives, dividends and interest into one Self Assessment-ready workflow.

If you sold ETH, disposed of shares and received dividends during the same tax year, Koinly covers only the crypto activity. The broker history needs a separate calculation before you can complete the return. Finbooks connects brokers, exchanges and wallets in the same account, with unlimited imported transactions and connected sources on every plan.

Finbooks Basic starts at £39 a year; Koinly's first paid tax-report plan is listed at $49 for up to 100 transactions. This guide compares their coverage, pricing, workflow and support so you can see which product fits the position you actually need to declare.

Finbooks vs Koinly at a glance

Both products can turn crypto activity into UK capital gains and income figures. The dividing line is the rest of your portfolio: Koinly remains a crypto tax product, whereas Finbooks carries the same process across traditional investments as well.

What does Koinly cover and where does it stop?

Koinly covers crypto activity across exchanges, public wallet addresses and more than 900 advertised integrations, including transactions involving staking, mining, NFTs and DeFi. Its UK reports apply pooling, same-day matching and the 30-day rule, while the free version lets you inspect the crypto calculation before purchasing a report.

The coverage ends with crypto. Koinly does not calculate shares, ETFs, bonds, derivatives, dividends or interest from your broker, and it cannot show how those amounts fit into your complete investment tax position. Even a fully reconciled Koinly report therefore solves only one part of the return when you invest across both markets.

Where does Finbooks cover more than Koinly?

Your Self Assessment does not split itself by app. A crypto disposal may create a capital gain, a broker may show a loss on shares, an ETF may distribute foreign income and cash held on the platform may earn interest. Those figures interact with the same allowances, loss position and wider return.

Finbooks lets you import the broker accounts alongside exchanges and wallets, then applies the relevant UK treatment to each part of the history. Crypto gains still follow the pooling and matching rules, while share disposals, dividends, interest and other investment income are kept in their correct categories for Self Assessment.

That broader scope removes an awkward gap. With Koinly, the crypto report can be complete in its own right while the rest of your investment tax still sits elsewhere. With Finbooks, both sides remain visible in the same workflow and feed into the reports you use to prepare the return.

A practical example

Suppose you sold ETH through two exchanges, disposed of shares through Interactive Brokers, received US dividends and earned interest on uninvested cash. Koinly can calculate the crypto side, but the broker activity needs a separate process. Finbooks reconstructs both histories, converts the relevant amounts into pounds and organises the resulting gains and income for the same tax year.

How do Finbooks and Koinly prices compare?

The headline prices only become useful once you include their limits. Finbooks Basic costs £39 a year and already includes unlimited imported transactions, unlimited connected sources, crypto and traditional finance, and Self Assessment-ready reports. The £99 Pro plan keeps those limits unlimited and adds portfolio tracking, automatic data syncing and tax-planning tools.

Koinly's free version lets you import crypto and preview the calculation, but it does not include downloadable tax reports. Newbie costs $49 per tax year for up to 100 transactions, Hodler costs $99 for up to 1,000 and Trader starts at $199 for 3,000 or more. Deposits and withdrawals can count towards the total as well as trades, so the required tier may be higher than your number of executed trades initially suggests.

Will both products calculate UK crypto tax correctly?

Both products are designed to apply the UK crypto calculation rather than treating every sale independently. They account for income and disposals, work in pounds and apply the same-day, 30-day and pooled-cost rules used for UK cryptoassets.

The difference lies in scope, not in pretending that one set of HMRC rules belongs to one brand. Koinly applies those rules across your crypto history. Finbooks applies them to crypto while also calculating the traditional investments that sit alongside it in your return.

Whichever product you use, the output still depends on the quality of the history. Missing wallets, duplicate imports, unlinked transfers and incorrect transaction labels can all change the result. Review the anomalies and the supporting transactions before treating any total as ready to file.

What support do you receive?

Koinly includes email and chat support with its paid tax-report plans, while the free version is self-service. Users who want professional help can look for an accountant through Koinly's external directory, but there is no equivalent personal plan in which Koinly takes responsibility for completing the work inside the product.

Finbooks varies the level of help with the plan. Basic includes email support, while Pro adds chat. If you do not want to reconstruct and review the position yourself, Human assigns a dedicated tax specialist who takes the work through to the finished output and gives the case fast-track support.

That final option is a material distinction for complicated histories. You do not have to export the portfolio into a separate service or begin the reconstruction again: the specialist works with the history already held in Finbooks.

Can you switch from Koinly to Finbooks?

Yes. You can bring the exchange and wallet history into Finbooks and add any broker or investment accounts that were outside Koinly. The imported data should still be reviewed, especially where earlier transactions were corrected manually or a transfer was matched differently in the previous system.

Finbooks currently also offers to refund the cost of another investment-tax software you have already purchased when you activate a Finbooks plan and provide proof of purchase. Check the live offer terms before subscribing, as promotions can change.

Should you choose Finbooks or Koinly?

Koinly remains a viable option only when the tax position you want to calculate is entirely crypto. The moment shares, ETFs, dividends or other broker activity enter the return, you need a second process and must reconcile its output with the crypto report.

Finbooks is the stronger choice when you want your full investment tax position in one place. Basic already covers crypto and traditional finance with unlimited transactions for £39 a year. Pro adds the tracker, automatic syncing and planning tools, while Human gives you a route to delegate the work without moving the portfolio into another system.

The choice therefore comes down to the boundary of the job. Koinly stops after producing the crypto figures. Finbooks continues through the traditional investments and income needed to prepare your complete UK investment tax position.

Bring the whole investment history into the calculation

A good crypto report solves one important part of your return. For many UK investors, however, that part now sits beside brokerage accounts and investment income that need the same level of reconstruction and review. Finbooks brings those records together, applies the relevant UK treatment and prepares the reports from one underlying history.

You can start with the 7-day free trial, import the accounts you actually use and see whether a single investment-tax workflow suits you better than a separate crypto-only report.
