pump.fun and taxes

This is general information, not tax advice. Rules differ by country and change often. For anything beyond a few small trades, use a tax professional who knows crypto.

What pump.fun says

pump.fun puts the whole job on you:

• “You are responsible for determining and paying all applicable taxes related to your use of the Pump Platform” (Terms §29.16).
• It “do[es] not provide tax advice in any jurisdiction” (§4.6, on creator fees).
• For Holder Rewards (§4.8(i)) and referral fee share (§4.9(i)) it may ask for identifying or tax information, withhold amounts, or report payouts to authorities where the law requires.
• Competition prizes may have tax withheld, and winners may be asked for tax documents (Competition Terms, Taxes).

We found no tax form or downloadable tax report in pump.fun’s published pages as of 4 November 2026. Your records are up to you.

Events that are usually taxable

Event	Usually treated as
Selling a coin for SOL or USDC	Disposal: capital gain or loss
Swapping one coin for another	Disposal of the first coin
Spending SOL to buy a coin	Often a disposal of the SOL itself (it may have changed in value since you got it)
Creator fees received	Income when received
Holder Rewards, cashback, callout rewards	Usually income when received
Referral fee share	Usually income
Competition prizes, bounties	Usually income
Moving coins between your own wallets	Usually not taxable, but keep the record
Fees paid (curve, Platform Fee, network)	Usually added to cost or deducted from proceeds

The third row catches many people: on pump.fun you usually buy coins with SOL, so each purchase can also be a sale of SOL.

What to record for every trade

• date and time (UTC);
• the coin’s contract address (names repeat, addresses don’t);
• amount bought or sold, and the SOL or USDC paid or received;
• the value in your currency at that moment;
• fees: pool fee, the 0.45% Platform Fee, network fees;
• your wallet address and the transaction signature.

Everything is on the public Solana ledger, so you can rebuild it from your wallet address with a block explorer or a crypto tax tool that reads Solana wallets. Export at least yearly; small coins vanish from data providers quickly.

Losses

Most pump.fun coins lose most of their value. In many countries a realised loss can offset gains. Some tax authorities want the coin actually sold or disposed of before a loss counts, and a coin with no buyers can be hard to sell. Rules on worthless assets vary, so ask a professional.

Country pointers

• United States: the IRS treats digital assets as property. Gains and losses go on your return, and every Form 1040 asks whether you received or disposed of digital assets. IRS digital assets.
• Canada: the CRA treats crypto gains as business income or capital gains depending on how you trade. CRA crypto-asset information.
• Australia: disposing of a crypto asset is usually a capital gains tax event. ATO: tax and crypto asset investments.
• United Kingdom: pump.fun is not available in the UK. HMRC’s cryptoassets guidance covers holdings from before the block.
• Elsewhere: search your tax authority’s site for “crypto” or “digital assets”. Many countries treat each swap as a disposal.

Keep the cost in view

Fees reduce your gains or increase your losses, and on pump.fun they’re large: 1.70% each way on the bonding curve in the app. The fee calculator shows the round trip, and how to sell and withdraw covers getting to cash.
