# Token Limitations

> Token types Sonar can’t fully support, and what happens when you use them.

Most tokens work on Sonar. A few token types charge a tax or pay out rewards in a way that doesn’t fit how Sonar trades and holds them.

| Token type | Works on Sonar | What happens |
| - | - | - |
| Sell tax | No | Sonar can’t trade tokens that charge a tax on sells. |
| Transfer tax | Yes, with a loss | The tax is taken on every transfer, including moves into the Vault. |
| Reward or reflection | Yes, without rewards | Tokens in the Vault don’t receive their rewards. |

## Sell Tax Tokens

Some tokens take a percentage every time someone sells. Sonar doesn’t support them, so strategies and swaps with these tokens won’t work.

## Transfer Tax Tokens

These tokens take a percentage on every transfer. You can use them on Sonar, but each move costs you the tax.

Funding the Vault moves the token twice: from your wallet to your Vault address, then into the Vault. The tax is taken on both moves, so less arrives than you sent.

> [!WARNING]
>
> **Check The Tax First**\
> A 5% transfer tax costs you close to 10% of the tokens on the way into the Vault.

## Reward And Reflection Tokens

Some tokens pay holders a share of every trade, or send them reward tokens. Tokens held in the Vault don’t receive these rewards.

> [!TIP]
>
> **Want To Keep Earning?**\
> Keep reward tokens outside the Vault, and only move what you plan to trade.
