For tax year 2025, all documents were submitted and a written agreement was signed for this firm in February to complete my taxes. Tax day passed and there was zero communication on the status of my taxes. Calls, texts and emails were ignored or pushed aside before this firm stopped responding altogether. I had to contact the IRS to confirm that this firm failed to file my taxes. To this day no apology or explanation has been given. Do not trust this business to handle your taxes.

Update 2026/03/05:…read more The maintenance issue was resolved on March 2, 2026. After I posted the February 26, 2026 review (see below) and emailed multiple people at Onyx Capital Management on February 26, 2026, Mr. Zachary G., the maintenance manager, personally intervened, reviewed my video evidence accurately, apologized and took full accountability for an initial vendor error. He ensured the repair was completed promptly and followed up with professionalism. I am updating this review to reflect that the operational failure was eventually corrected. However, I am raising this review from a 1-star to only a 3-star rating because the administrative process remains a concern. The general manager, Ms. Victoria L., prematurely dismissed my concern and deleted my community post shortly after it was uploaded. She also posted a public comment stating that the lamppost had been fixed, based on an inaccurate assessment of my video evidence. Furthermore, she did not reach out directly to clarify or correct that public statement once the error was identified. While the maintenance leadership is professional and capable, the administrative side of the business still has significant room for growth regarding transparency, due diligence, and resident communication. ------------------------------------------ Feb 26, 2026 My HOA has Onyx Capital Management as our management company. On 11/28/2025 I submitted a maintenance request for the replacement of a lightbulb of the lamp post facing my rear door. As for 2/26/2026, almost 3 months later, the lightbulb is still not replaced. I sent video evidence that it is not fixed. They replied with a photo of a working lamp post, not the one that is broken. Thus far, this company has FAILED miserably at keeping the promise stated on their company website: "At Onyx Capital Management, we set the utmost standards to provide care, support, and quality to our homeowners and Board Members." I have sent multiple emails and called a couple of times. I have been patient. But this latest replay is the last straw. Onyx Capital Management's failure in this case is completely unacceptable. ------------------------

I was comfortable negotiating terms with Vicky and Zach and I knew they understood every concern and past mistakes the new Board didn't want to repeat. Our Onyx contract is still only 4 months old but after our community town-hall tonight, The Board and and community have expressed nothing but praise for our new management company. Our files, documents, investments, and our money is respected. The quality of work contractors they have recommended and brought to us have exceeded expectations.
