Why Track Crypto Card Spending in Koinly?

Crypto-card transactions create a unique tax challenge. Unlike traditional credit cards, every purchase involves a stablecoin transfer, FX conversion, or cashback deposit — all of which have tax consequences.

Cashback is taxable income at fair-market value on the date received. A USD/EUR conversion triggers a capital gain or loss if you later sell the stablecoin at a different price. Card fees may be tax-deductible depending on your jurisdiction. Koinly handles all of this automatically, saving you hours of manual spreadsheet work.

Signal: Failing to report crypto-card income and gains to your tax authority can trigger audit risk or penalties — accurate Koinly tracking protects you. The IRS, HMRC, and EU tax authorities now scrutinize crypto income closely.

Getting Started With Koinly

Koinly is a cloud-based crypto tax platform that tracks transactions across 500+ exchanges, wallets, and now, crypto-payment cards. Setting up takes under 5 minutes.

Step 1: Create Your Account Visit koinly.io and sign up with your email. Choose your country — this determines which tax forms Koinly generates for you (1040 for US, SA103S for UK, etc.).

Step 2: Choose Your Import Method Koinly offers three ways to import ether.fi card transactions:

  • API integration (recommended): Direct connection syncs transactions automatically. Koinly receives read-only access — it cannot withdraw funds.
  • CSV upload: Export statements from ether.fi and upload manually. Useful if you prefer full control or have gaps in API history.
  • Manual entry: For transactions Koinly missed. Rarely needed with API setup.

Key metric: Koinly’s auto-categorization engine uses machine learning to classify 70–80 % of transactions correctly on first import, saving hours of manual review.

How to Import ether.fi Transactions Into Koinly

The API method is the standard. Here’s the step-by-step process:

Setting Up the API Connection

  1. Log into your Koinly dashboard.
  2. Click “Add Wallet/Exchange” (top right).
  3. Search for “ether.fi” in the dropdown.
  4. Click “Connect”.
  5. You’ll be redirected to ether.fi to authorize Koinly. Review the permissions (read-only access to transaction history).
  6. Click “Approve” on ether.fi.
  7. Return to Koinly. The import starts automatically.
  8. Transactions appear in your dashboard within 1–5 minutes.

How to Import ether.fi Transactions Koinly — after your first sync, Koinly continues pulling new transactions daily. You can manually refresh anytime by clicking the refresh icon next to the ether.fi connection.

Handling CSV Imports

If API isn’t available in your region or you prefer manual uploads:

  1. Log into your ether.fi Cash account.
  2. Navigate to “Statements” or “Transaction History”.
  3. Select your date range and click “Download CSV”.
  4. Return to Koinly and click “Add Wallet/Exchange” → “CSV Upload”.
  5. Select the file and map the columns (Date, Amount In, Amount Out, Fee, etc.).
  6. Review the preview and click “Import”.

Why it matters: API import reduces manual data-entry errors, keeps your records in real-time sync with spending, and is audit-proof because Koinly’s records match your official statement.

Categorizing Cashback and FX Conversions

Once imported, Koinly shows a list of transactions. Each needs categorization — this step determines how the transaction appears on your tax return.

Categorizing Cashback

ether.fi Cash pays cashback in the same stablecoin (usually USDC). Mark this as “Income” in Koinly — specifically, use the “Cashback” subcategory if available, or “Other Income” if not.

Example: You spend $100 and receive $3 USDC cashback. Koinly shows two rows:

  • Outflow: $100 (your purchase)
  • Inflow: $3 USDC (mark as Income).

On your tax return, you’ll report the $3 as taxable income at fair-market value on the date received.

Categorizing FX Conversions

If you spend in EUR and your account is in USD, Koinly auto-detects the conversion. The system assigns a cost basis based on the spot exchange rate at transaction time.

Example: You spend €100 when 1 EUR = 1.10 USD, so your cost is $110. Three months later, you convert that EUR to USD at 1 EUR = 1.12 USD, yielding $112. Koinly calculates a $2 capital gain.

Most users accept Koinly’s auto-categorization for FX conversions — it’s accurate and audit-proof.

Advanced Features and Custom Categorization

If you’re researching how to use borrow mode ether.fi or other advanced tier features (available on Luxe and Pinnacle accounts), categorize loan proceeds separately:

  • Loan received: Mark as “Liability” (not income).
  • Loan repayment: Mark as “Expense” or offset the original liability.

Consult your tax advisor on the proper treatment in your jurisdiction.

Risk: Miscategorizing a deposit as a “Transfer” instead of “Income” can trigger audit flags during automated IRS matching. Koinly’s category guidance is conservative — use it.

Tax Reporting and Year-End Reconciliation

Koinly generates three key reports:

1. Capital Gains Report Shows every gain and loss from FX conversions, stablecoin redemptions, or asset swaps. Broken down by transaction type, holding period (short-term vs. long-term), and date.

Example output:

  • Date: 2026-03-15
  • Asset pair: EUR → USD
  • Cost basis: $1,200
  • Sale price: $1,224
  • Gain: $24 (short-term)

2. Income Report Lists all cashback, airdrops, and staking rewards. Totals by year and category.

Example:

  • Cashback from ether.fi Cash: $432.50
  • Date range: Jan 1 — Dec 31, 2026
  • Fair-market value: Calculated at transaction date

3. Tax Summary (Country-Specific) For US users, Koinly generates a summary compatible with Form 8949 (capital gains) and Schedule 1 (other income). UK users get a summary for the UK tax return. EU users get POAO (pro rata acquisition) calculations required by MiCA regulations.

Exporting and Filing

30 days before your tax deadline, export all three reports as PDF. Many accountants accept Koinly exports directly — you don’t need to manually re-enter data into your tax software.

Watch: Tax laws are evolving. The US IRS, UK HMRC, and EU tax authorities have issued new guidance on crypto-asset reporting. Verify your jurisdiction’s 2026 rules before filing — Koinly updates its forms annually, but rules vary by region.

What to Watch

  • Sync health: Check your Koinly dashboard weekly. If the ether.fi connection shows “Last sync: 8+ days ago,” manually refresh or re-authorize.
  • Cashback timing: ether.fi posts cashback 1–3 days after a purchase. Verify it’s arrived before reconciling your Koinly dashboard.
  • FX rate drift: Koinly uses the official rate at transaction time. If you see a cost basis that doesn’t match your expectation, check the historical spot rate for that date.
  • Tax-law updates: Q1 every year, check your tax authority’s website for new guidance on crypto-card reporting.
  • Account security: Enable 2FA on both ether.fi and Koinly. Never share API keys or seed phrases with anyone, including Koinly support.
  • Data export cadence: Download a backup of your Koinly data quarterly to an encrypted drive — this prevents loss if Koinly goes offline.

Bottom Line

  • If you’re a regular ether.fi Card user making 10+ transactions per month, importing transactions into Koinly saves at least 5 hours at tax time.
  • Set up API import today so transactions sync automatically — this gives you a full year of clean, categorized records before next April.
  • Review your Koinly dashboard quarterly to catch miscategorizations early and confirm sync is working.
  • Tax tracking is no longer optional: major exchanges and card issuers now report to tax authorities. Use Koinly to stay compliant and defend yourself in an audit.
