# Launch Week IV Day 3: Lago × Avalara Integration —  End Tax Guesswork

### Automate tax calculation through Lago

Lago’s native tax feature engine is perfect for straightforward EU VAT, but once you get into the questions like whether you have to pay taxes in Illinois because Matt from accounting has a summer home there… you’ll need a dedicated tax solution like Avalara, especially relevant to [tax compliance in billing](https://getlago.com/blog/kyc-and-aml-for-fintech-billing-implementation-guide) for regulated industries.

Now, all Lago customers can stop worrying about that complexity and use our native Avalara integration to calculate taxes for all invoices — [tax automation as a billing feature](https://getlago.com/blog/billing-system-evaluation) that's worth evaluating alongside everything else.

It’s simple to set up:

### One-time tax set-up

1. **Connect Lago to Avalara** in *Settings → Taxes → Avalara*.
2. **Map addresses** Lago already stores your customer’s billing or shipping location.
3. **Ship invoices as normal** Lago calls Avalara’s API in real time, returns the exact rate, and prints the tax line, including for complex scenarios like credit notes, voids, top-ups and refunds? Covered.
