Try Free DemoNNS Tax Pro reads the CSV export from the Network Nervous System dApp and pools ICP under UK Section 104 rules. Follow these six short steps to download your account history — no technical knowledge required.
In your browser, go to nns.ic0.app and log in to your NNS dApp account using the Internet Identity passkey prompt. The Network Nervous System dashboard loads — this is the official app for managing your ICP accounts, neurons, and canisters. No download is required; it runs entirely in your browser.
NNS dApp sign-in uses Internet Identity passkeys — there is no password or seed phrase to enter. NNS Tax Pro never sees, transmits, or stores your seed phrase, password, or wallet credentials.
From the NNS dApp dashboard, navigate to the Account section. This is where your ICP account balances and transaction history live.
Within the Account section, select Reporting and then click Transactions. This opens the transaction reporting view where you can filter and export your ICP activity.
In the reporting view, open the source token/account selector and set NNS as the source so the export covers your ICP transactions on the NNS dApp. NNS Tax Pro pools ICP under UK Section 104 rules, so export your ICP account history here.
Open the date range picker and choose the reporting period you want to cover — for example, the full UK tax year. The reporting view will filter your ICP transactions to that period.
Click Export to download your raw .csv transaction file. Your browser saves a CSV containing every ICP transaction for the selected account and date range. Upload this file to NNS Tax Pro to preview your UK Section 104 summary.
The exported CSV contains your full ICP transaction history — store it securely and only upload it to NNS Tax Pro over a trusted connection.
After uploading your CSV exports and running the calculation, the report preview is blurred and locked. You can unlock both PDF and JSON downloads using either checkout rail:
At checkout you can optionally enter an email address to receive an automated PDF receipt or invoice with your on-chain transaction proof (or Stripe session reference). You can re-send the same PDF receipt at any time from the My Unlocked Reports dashboard — no need to re-enter payment details.
The report preview and the My Unlocked Reports dashboard show a live price badge for ICP, alongside a historical rate trend chart. The chart traces the GBP rate for ICP over your selected date range so you can see how cost basis and proceeds were valued over time.
Open the dashboard, upload your exported NNS CSV for ICP, and preview your UK Section 104 summary free — no sign-in required to preview.
