Discover how BlackLine Tax Group was founded to solve the real tax challenges traders face.


Taylor Gartica & Nolan Knight founded BlackLine Tax Group to solve a real problem: traders deserve tax filing software designed by people who actually trade. Most tax services treat traders like everyone else. We don't. We understand wash sales, Section 1256 contracts, day trading losses, and the complexity of multiple accounts because we've lived it. Our mission is to make tax filing less painful and more accurate for the trading community.
BlackLine Tax Group is built by people who understand trading taxes from the inside. We combine real trading experience with CPA expertise to solve the tax challenges traders actually face.
Founder
Taylor established BlackLine Tax Group to resolve the complex tax reporting challenges traders face each year. In collaboration with licensed CPAs and informed by direct trading experience, the firm integrates rigorous compliance expertise with practical market insight.
Managing Director
Nolan, CPA and Managing Director at BlackLine Tax Group, oversees tax compliance, technical review, and regulatory standards across all engagements, providing licensed oversight for complex individual and business filings, including high-volume trading and entity structures.
Early adopters are getting specialized tax filing built for their trading strategies, not generic returns.
Finally a tax service that understands day trading. They caught deductions I'd missed for years and made the whole filing process straightforward.

BlackLine gets it. As an options trader, I've always felt like I was forcing my tax situation into cookie-cutter software. Not anymore.

Built by traders for traders. The support I got was specific to my strategy, not generic advice. That made all the difference.
