Bitcoin Taxes for Beginners: What to Track

Bitcoin taxes come down to what you track: five fields, taxable vs. non-taxable events, Form 1099-DA, and the wallet-by-wallet basis rules explained.

Here is the practical answer up front. For every bitcoin transaction, track five things at the moment it happens: the date and time, what you received or gave up (amount in BTC), the fair market value in US dollars at that moment, any fees paid, and which wallet or account it happened in. Capture those five fields from day one and every tax season becomes an export. Skip them and you will someday reconstruct years of history from exchange screenshots and blockchain explorers — usually in April, usually at billable rates.

The reason this matters more now than it did two years ago: the IRS started receiving broker reports on digital-asset sales (Form 1099-DA) for 2025 transactions — but in its first year that form reports your gross proceeds without your cost basis. The IRS increasingly sees what you sold. Proving what you paid is still entirely your job.

One scope note before anything else: this is US-focused education, not tax advice. Rules change, situations differ, and the cost of a good crypto-literate CPA is small next to the cost of guessing wrong.

The one-sentence mental model

The IRS treats bitcoin as property, not currency. Everything else follows from that sentence: disposing of property triggers a capital gain or loss against your cost basis, and receiving property as payment or reward is ordinary income at its dollar value on arrival, per the IRS digital-asset rules. Bitcoin's tax problem isn't that the rules are exotic — it's that a currency-shaped asset generates property-shaped paperwork every time it moves.

What's taxable, what isn't

Not taxable:

Buying bitcoin with dollars and holding it. No matter how far it rises, unrealized gain is not a taxable event.
Moving bitcoin between wallets you control. Exchange to hardware wallet, hot wallet to cold — not a disposal. (Track the move anyway; you'll see why below.)

Taxable:

Selling for dollars. Capital gain or loss versus your basis.
Spending it. Buying anything — a laptop, a coffee — is legally a disposal of property at that moment's price. More on this below.
Trading one crypto for another. A disposal of the coin you gave up.
Earning it. Mining rewards, payments to your business, interest, referral bonuses — ordinary income at fair market value when received. That value also becomes your basis in the coins.

The five fields, and why each one earns its place

Date and time — determines the price used, and whether a later sale is short-term (ordinary rates) or long-term (over one year, preferential rates).
Amount and direction — what came in or went out, in BTC.
Fair market value in USD — the number income and gains are measured in. Capture it at transaction time from your exchange confirmation or a price index; reconstructing "what was bitcoin worth at 2:14 p.m. three Julys ago" is exactly the misery you're avoiding.
Fees — exchange and network fees generally adjust your basis or reduce proceeds; small numbers, but they compound over hundreds of transactions.
Wallet or account — this one became load-bearing in 2025.

The rules changed in 2025 — most beginner guides are stale

Two changes made record-keeping stricter, and both reward people who track from day one.

Wallet-by-wallet basis is now mandatory. Before 2025, many filers pooled cost basis across every wallet they owned ("universal" tracking). Under Rev. Proc. 2024-28, that ended: from January 1, 2025, basis must be tracked per wallet or account. When you move coins between your own wallets — still not taxable — their basis and acquisition dates must move with them, ledger-style. This is why "which wallet" is one of the five fields.

Brokers now report your sales. Form 1099-DA began with 2025 transactions. Two things beginners consistently get wrong about it, per the IRS's own broker-reporting FAQ: first, in its debut year it reports gross proceeds only — no basis — so the IRS may see a $30,000 sale and nothing about the $28,000 you paid; your records supply the difference between a $2,000 gain and a $30,000 one. Second, basis reporting from 2026 onward only covers assets bought and held at that same custodial broker. The moment coins touch self-custody — where many holders keep long-term positions for good reasons — no broker can report basis for you. Self-custody means self-reporting, forever.

The latte problem (spending bitcoin)

Because spending is a disposal, a $9 latte paid in sats is, technically, a micro capital-gains event: what did those sats cost you, what were they worth at the register, gain or loss on the spread. Nobody enjoys this; it is still the law. The operator move is structural: if you want to spend bitcoin regularly, consider a dedicated spending wallet funded deliberately, so the taxable noise stays in one place with clean records — and your long-term stack sits untouched in another wallet, per the same separation logic in should a small business hold bitcoin. Wallet-by-wallet rules actually make this cleaner, not harder.

Earning bitcoin: two tax layers, one common trap

If your shop accepts bitcoin payments or you mine — you can estimate what a machine actually earns with our mining profitability calculator — every receipt is ordinary income at fair market value on arrival. That's layer one, and it's taxable even if you never sell. Layer two comes later: sell or spend those coins and you owe capital gain (or claim loss) versus the basis set at receipt.

The trap: a miner or merchant who received bitcoin all year and "didn't sell, so there's nothing to report" has it exactly backwards — the income already happened, priced at each day's receipt. Businesses should also know their books changed in 2025: under FASB's fair-value rules covered in our treasury piece, GAAP filers now mark holdings to market through net income. Bookkeeping and taxes will both ask for the same clean records.

Losses are useful — if you tracked

Sell below your basis and the capital loss offsets gains (and up to $3,000 of ordinary income per year, with carryforward). One quirk worth knowing: as of this writing, the wash-sale rule does not apply to bitcoin held directly — it covers securities, and the IRS classifies bitcoin as property — so selling at a loss and promptly rebuying doesn't automatically void the loss the way it would with a stock. Two cautions: spot-bitcoin ETF shares are securities, where wash-sale rules do apply; and Congress has repeatedly proposed closing this gap, so confirm current law before acting on it. None of it works, though, without basis records proving the loss exists.

What this changes in the real world

A tax position is downstream of a record-keeping habit. Concretely: keep exchange CSV exports (don't assume a platform will exist, or keep history, forever), let a crypto tax tool or a spreadsheet capture the five fields as you go, give every wallet a name and a job, and never mix spending, operating, and holding coins in one place. Ten minutes a month, or a forensic project every April — that's the actual choice. For the foundations under all this, start with our Bitcoin 101 guide, and if it's business money, the small business owner's guide covers the operational side.

FAQ

Do I owe taxes if I just buy and hold bitcoin?

No. Buying with dollars and holding is not a taxable event, no matter the unrealized gain. Taxes arrive when you dispose — sell, spend, or trade — or when you earn bitcoin, which is income at receipt. You should still record every buy: today's purchase is tomorrow's cost basis.

Is moving bitcoin between my own wallets taxable?

No — transfers between wallets you control are not disposals. But under the wallet-by-wallet rules effective in 2025, the coins' basis and acquisition dates must follow them to the new wallet, and any network fee is worth recording. Untracked self-transfers are the #1 way otherwise-clean records rot.

The exchange sends the IRS a 1099-DA — doesn't that mean my taxes are handled?

No. In its first year the form reports gross proceeds without cost basis, so the IRS may see your sale amount but nothing about what you paid. And broker basis reporting, once it starts, only covers coins bought and held at that same custodial broker — anything that touched self-custody is yours to substantiate. The 1099-DA raises the cost of sloppy records; it doesn't replace them.

I mined / got paid in bitcoin and haven't sold. Do I report anything?

Yes — that's the common trap. Bitcoin received from mining or as payment is ordinary income at its fair market value on the day it arrived, sell or not. That value becomes your basis; selling later is a second, separate gain-or-loss event. Track every receipt with its date and dollar value.
