On Solana, anyone can launch a token with the same name, symbol and logo as another one. If your trade log identifies tokens only by ticker, two different coins can quietly share one FIFO pool, and nothing in the sheet looks broken. Here's how that happens and how to label rows so it can't.
Solana's documentation says that "Tokens on Solana are uniquely identified by the address of a Mint Account" (solana.com/docs/tokens). Jupiter's Token API docs make the same point from the other side: "a symbol such as USDC or JUP can be claimed by any mint", so you should "store and look tokens up by mint, never by symbol" (developers.jup.ag/docs/tokens).
In the Nah Crypto Tax Tracker workbook, FIFO matches each Sell against earlier Buys with the same Token text. Upper and lower case and leading or trailing spaces are ignored. We tested this: rows labelled "Bonk ", "BONK" and "bonk" were treated as one token, and the holdings line showed a single BONK.
Handy for typos, but two different mints both typed as "MOON" become one pool.
You buy the real MOON, and the next day you buy a look-alike MOON by mistake. You sell the look-alike in November and the real one in February. All numbers are EXAMPLE values; the fee is in fiat.
| Date | Type | Token | Qty | Price | Fee |
|---|---|---|---|---|---|
| 2025-10-01 | Buy | MOON | 10 | 30.00 | 0.50 |
| 2025-10-02 | Buy | MOON (look-alike) | 50,000 | 0.001 | 0.20 |
| 2025-11-05 | Sell | MOON (look-alike) | 50,000 | 0.0001 | 0.10 |
| 2026-02-10 | Sell | MOON | 10 | 20.00 | 0.50 |
Both labelled "MOON". FIFO takes the oldest units first, so the November sale of the look-alike uses up the 10 real MOON plus 49,990 look-alike units. The workbook shows a cost of 350.69 against proceeds of 4.90, a realized result of −345.79 in 2025. The February sale of the real MOON is then matched against the last 10 look-alike units (cost 0.01), giving +199.49 in 2026.
Labelled "MOON-A1B2" and "MOON-Z9Y8". Each sale finds its own lot. The look-alike shows −45.30 in 2025 (cost 50.20) and the real MOON shows −101.00 in 2026 (cost 300.50).
The all-time total is −146.30 either way, but the per-year Summary differs: −345.79 / +199.49 versus −45.30 / −101.00. Every row in the Check column says OK in both versions. The OVERSOLD flag only fires when a Sell exceeds the earlier Buys of that label, and a merged pool has plenty of units. So the sheet cannot warn you; the labels have to.
Swaps stay two rows: a Sell of what you gave and a Buy of what you got, with the same signature in G. For fees: enter the combined fee once per swap, on the token's row, in fiat, and do it the same way all year.
Look-alikes also arrive unasked: Phantom's help center says "anyone can send tokens or collectibles to your wallet without your permission" and that an unfamiliar asset is "usually spam" (help.phantom.com). Airdrops are not calculated automatically: you can log them manually as a Buy row at a value you choose (e.g. 0 or fair value; ask an advisor which), as explained in the guide. If you add one, give it its own mint-suffixed label.
How any of these rows is treated for tax purposes is a question for a tax professional.
If you'd rather not build this yourself, the Nah Crypto Tax Tracker is an .xlsx plus a PDF guide with plain formulas and no macros: Buy/Sell rows, Tx hash in G, Notes in H, FIFO by date then row order, an OVERSOLD flag and a per-year Summary. FIFO only; not tailored to any country's tax rules. 29 USDC one-time: Nah Crypto Tax Tracker. Related: own-wallet transfers and reconciling Phantom history. Not tax advice.
