Year-end tax statement: what's in it and how to use it

Crypto and tax season usually means digging through CSV exports from five different exchanges, guessing at cost basis, and hoping the numbers line up. We do that work for you. Every buy, sell, and auto-invest you make on 401jk.app is recorded with a USD snapshot at the moment it settles, so generating a clean year-end statement is one tap.

What you get

Visit /tax, pick a year and your country, and we generate a printable report. Hit Print, save as PDF, and hand the file to your accountant. Or download the CSV and import it into the tax tool of your choice.

If you're in the US

The report includes a Form 8949 Attachment Statement in the exact column order the IRS expects (description, acquired, sold, proceeds, cost basis, gain/loss, term). Attach it with your Form 8949 and enter the totals; the IRS accepts a summary statement as a substitute for filling out each line. There's also a Schedule D summary with the short-term and long-term splits already calculated. FIFO is the default; pick HIFO from the dropdown if your records support it.

If you're in the UK

Section 104 pooled-basis summary, formatted for HMRC. Total disposal proceeds, allowable costs, gain or loss per disposal. Verify same-day and 30-day adjustments with your accountant before you file the Self Assessment.

If you're in Germany

FIFO with the §23 EStG one-year holding rule applied per disposal. The report flags each row as “exempt” (held over 12 months, tax-free under the private-sale exemption) or “taxable”. Your tax advisor (Steuerberater) can lift the numbers straight into Anlage SO.

If you're elsewhere

France, Sweden, Norway, Canada, Australia all have presets that use the cost-basis method your local tax authority expects (average cost in most of Europe; FIFO in Norway and Australia; ACB in Canada). For everyone else, “Other / Worldwide” gives you a generic FIFO/HIFO/average-cost summary in USD that any accountant can work with.

How the math works

At the moment each trade is confirmed on Solana, we save the USD value of the SOL leg (using a server-side price snapshot) so reports always reflect what the trade was actually worth at that moment, not whatever the price source happens to say later. The cost-basis engine then walks your trades in order, matching each sale to earlier buys using the chosen method, and emits per-disposal gain/loss with holding-period classification.

Free, no third-party account required

Reports come from us directly. There's no Koinly subscription to set up, no CoinTracker account to link. The CSV export is in a generic format that imports cleanly into any of those tools if you want to double-check, but it's strictly optional.

What we're not

We're not your tax advisor. The report is an informational summary that gives your accountant or your tax software everything they need to file accurately. We don't file anything on your behalf, and we don't claim the report substitutes for professional tax advice. Verify with a qualified tax professional before filing. Same advice we'd give for any other crypto product.
