# What Are Regulatory Fees (REG and TAF)?

This is a regulatory fee that is charged by the US government -specifically, the *Financial Industry Regulatory Authority (FINRA)* and the *Securities and Exchange Commission (SEC)* - on all "Sell" orders you make on Grifin (the stocks you sell).

Grifin does **NOT** benefit financially from these charges in any way, shape, or form. These charges are 100% passed on to the above government agencies in full:

- SEC regulatory fee for both equities and options: **$27.80 per $1,000,000** (sells only).
- FINRA Trading Activity Fee (TAF): **$0.000166 per share** (sells only). 
    - This FINRA transaction fee is rounded up to the nearest penny.
    - Max FINRA fee of $8.30.

### **NOTE: New regulatory fee update as of June 1, 2025:**

The **Consolidated Audit Trail (CAT)** introduced a new fee structure, which Grifin will be billed for. This fee will be charged per trade, but we will ***NOT*** pass this fee on to you (whereas, the existing REG/TAF fee mentioned above ***IS*** passed on to you).

The **CAT Fee rate** is based on executed equivalent shares. Current fee structure is:

**Equities (stocks)**

The CAT Fee is calculated at $0.000046 per share (1:1 ratio) as follows:

**Fee × Executed Equivalent Shares = CAT Fee**

**Do I have to pay for these fees separately?**

No, you do not pay regulatory fees separately. The ***"REG and TAF Fees"*** are automatically deducted from stock sale proceeds. As for the ***"CAT fees"*** cost, as mentioned above, Grifin covers that for you. :)
