Tax Form Collection: Stay Compliant, Pay with Confidence
Why This Matters
If you pay US-based affiliates more than $600 per year, you need their W-9 form. Non-US affiliates may need W-8BEN forms. Tracking who submitted what — and chasing missing forms — has always been a headache.
Now it happens automatically.
How It Works
Enable tax form requirements in your program settings (available on Elite). When an affiliate's earnings approach the threshold, they see a clear prompt to upload their tax form. Until it's submitted, payouts are held.
- W-9 for US affiliates reaching the $600 threshold
- W-8BEN for international affiliates when needed
- Automatic holds until forms are on file
- Clear messaging so affiliates know exactly what's needed
No more spreadsheets to track form status. No more surprise compliance issues at tax time.
For Your Affiliates
Affiliates see helpful guidance about which form they need and why. The upload process is straightforward.
