1. Why am I being asked to fill out a W-9 form?
We’re required by the IRS (U.S. tax authority) to collect taxpayer information from U.S. customers.
The W-9 form helps us verify your identity and report your crypto activity correctly for tax purposes.
This is the same process used by banks and investment platforms.
2. I’m not a U.S. citizen — why do I need to fill something out?
If you’re not a U.S. resident or citizen, but you reside in USA, you’ll complete a W-8 form instead.
It confirms that you’re not subject to U.S. tax reporting.
Once submitted, you won’t need to provide a W-9.
3. Is my information safe?
Yes — your tax information is handled securely through TaxBit, a trusted compliance platform used by leading crypto companies like Coinbase and PayPal.
All data is encrypted and protected following strict IRS and financial security standards.
4. What happens if I don’t complete the form?
If you don’t provide your tax information, U.S. law may require us to apply backup withholding, meaning 24% of your crypto sale proceeds could be withheld and sent to the IRS.
Completing the form ensures this doesn’t happen and keeps your account in good standing.
5. I tried to submit my form but got an error. What should I do?
Please double-check that:
- Name and address should match
- Your SSN or TIN is entered correctly
- You’ve signed and certified the form
If the issue continues, contact our Support Team → Category: Tax & Compliance, and we’ll help verify what went wrong.
6. Where can I find my tax forms later?
Once available, you’ll be able to view and download your tax forms (like 1099-DA) directly from your Settings → Tax Forms section in the app or web.
We’ll notify you when these forms are ready.
7. What is a 1099-DA form?
The 1099-DA is a new IRS tax form for crypto transactions.
It reports your total crypto sales or exchanges for the year — similar to the 1099-B form used for stock trading.
This helps you file your taxes accurately.
8. Why is Blockchain.com doing this now?
The IRS recently introduced new regulations for digital asset brokers (like Blockchain.com).
Starting in 2026, we’re required to report crypto transactions to the IRS using the 1099-DA form.
Collecting your W-9 or W-8 information now ensures we meet these requirements smoothly.
9. Who is TaxBit?
TaxBit is a tax compliance platform that automates crypto tax reporting.
They securely collect and verify your tax information and generate IRS-compliant forms.
They don’t access your funds — they simply manage the tax documentation process.
10. What if I already gave my SSN before?
If we already have your SSN on file, you might just need to confirm or complete a few additional fields in the W-9 form.
This ensures all information is accurate for tax reporting.
11. Will I receive a copy of my submitted W-9 or W-8?
You’ll get a confirmation that your form was submitted successfully, but not a downloadable copy of the W-9/W-8 itself.
For future tax forms like the 1099-DA, you’ll be able to download them from your account once they’re available.
12. Do I need to pay taxes through Blockchain.com?
No — we do not collect or file your taxes for you.
We’re only required to report your transaction activity to the IRS.
You should use the information we provide (like the 1099-DA) when you file your taxes with your accountant or tax software.
13. How long will it take to complete the process?
Filling out your W-9 or W-8 form usually takes less than 2 minutes.
Once submitted, you’ll see a confirmation that your information has been received securely through TaxBit.
