I needed a new accountant, and Seidy was quick to reply. He took care of my documents quickly and professionally, even asking questions that I didn’t know to ask myself. He and got them to me much faster than I expected, and I’ve been very happy and will continue to use his services.

Seidy was super helpful. I had multiple tax years in multiple states that felt like it was going to be a mess to do on my own. But, Seidy was patient and quick to respond to my questions

Seidy was very responsive to phone calls and messages through Thumbtack. He asked about other possible deductions that we may not have included with our tax docs. Once he completed our return, he reviewed it with me. He finished our return in under an hour. I will definitely use his services again if he’s available.

SL Tax, Accounting & Bookkeeping was great to work with on my 2025 taxes. He helped me understand some of the new tax laws and filed the paperwork for my LLC and rental property. It was a great one-stop-shop.
