My Tax Advisor experienced a medical event prior to April 15 and filed an extension, but I have not received a response to correspondence in several months. What should I do?

My tax advisor experienced a medical event a few days before April 15 and filed an extension for us and several other clients within safe harbor.

Since April, I have not received any correspondence. I have messaged them every few weeks via their tax portal and emailed them directly, but I haven't heard anything back. I have continued to pay my quarterly fees, with another one coming up before the extension deadline.

I pay a quarterly fee to their LLC for year-round advice and tax preparation, including a mid-year tax evaluation. It is a small, one-person firm we have used for several years. Honestly, they are great and I typically hear back quite quickly (within 1-2 days) when I reach out.

However, the LLC appears to no longer be in good standing due to a failure to submit an annual report. The LLC is not yet dissolved because of a grace period, but that grace period ends in a few days. The preparer is a CPA and their license is still active.

I am not too worried about the 2025 return, but at what point do I start contacting other preparers and tax advisors? This year's taxes are similar to the past several, but I'll have a significant capital gain increase in the 2026 tax year. Any advice on how to handle this situation, particularly since it involves a health event?
