REMAIN WELL INFORMED
OCP Tax Law is a boutique U.S. tax law firm in Houston, Texas that handles international tax, IRS disputes and collection, tax planning, compliance, and the tax side of mergers and acquisitions. The firm works with businesses, founders, executives, investors, and high-net-worth individuals who need senior-level attention on complex, high-stakes tax matters. Hablamos español.
Hire a tax attorney when your issue involves legal risk, a dispute, or attorney-client privilege — such as an IRS audit or appeal, unfiled foreign disclosures, tax debt you can’t pay, or structuring a cross-border transaction. A CPA is ideal for preparing and filing returns, while a tax attorney is built to defend positions, negotiate with the IRS, and design defensible strategies. OCP Tax Law pairs both perspectives, combining legal judgment with in-house accounting experience.
Fees depend on the complexity and type of matter — a one-time planning engagement, an IRS collection case, and an M&A deal are priced very differently. OCP Tax Law is a boutique firm, which means clients work directly with senior attorneys rather than being passed to junior staff, and pricing is scoped after an initial consultation. The firm offers a free consultation to assess the matter before any engagement.
Yes. OCP Tax Law offers a free initial consultation to review your situation, explain your options, and outline next steps before you commit. You can book it through the contact form on ocptaxlaw.com or by calling 832.390.2684.
OCP Tax Law is based in Houston, Texas at 700 Louisiana St., Suite 3950, and advises U.S. and international clients on federal tax matters, which apply nationwide. Because the firm focuses on cross-border and international tax, it regularly coordinates with foreign counsel and works with clients who live or do business outside the United States.
Yes – OCP Tax Law is a bilingual firm and serves clients in both English and Spanish. This is especially relevant for cross-border and international clients with ties to Latin America who need U.S. tax guidance in their own language.
The firm was founded by Oscar Carrillo, Managing Member, who concentrates on international tax planning and tax controversy for multinational businesses and high-net-worth individuals with complex cross-border transactions. He works alongside Perla Carrillo, who brings more than 18 years of combined accounting and tax experience, including audit work at a major CPA firm. Together they combine legal strategy with deep accounting and compliance expertise.
OCP Tax Law works with closely held businesses, founders and entrepreneurs, corporate executives, investors, and high-net-worth individuals — particularly those with international income, foreign assets, or cross-border operations. These are clients whose tax situations are complex enough that a mistake carries real financial and legal risk.
Yes. Communications with a tax attorney are generally protected by attorney-client privilege, which is one of the key reasons to use a law firm rather than a preparer when there is potential exposure — such as unreported foreign accounts or a possible audit. This privilege lets you disclose the full picture so the firm can build the strongest defense.
Complex tax problems rarely stay inside one category. A business decision can begin as planning, create a reporting obligation, and later become an IRS issue. OCP Tax Law uses its practice pages to separate those needs while keeping the legal strategy connected.
A tax planning attorney may become involved before a transaction, investment, restructuring, or ownership change. Once the decision is implemented, a tax compliance attorney may need to confirm that returns, information filings, and supporting records reflect the same position. This sequence helps reduce gaps between strategy and reporting.
If the IRS questions a filed position, a tax controversy attorney can focus on the examination, procedural rights, and the record supporting the taxpayer’s position. When the issue involves an unpaid balance rather than the validity of the assessment, an IRS debt attorney can evaluate the collection side separately.
An international tax attorney may address ownership, residency, income source, withholding, or foreign entities before a filing problem appears. Cross-border matters can also create reporting or controversy questions later, so the relevant practice should depend on the client’s immediate legal issue.
An M&A tax attorney becomes most relevant when a business acquisition, sale, or defined transaction moves toward negotiation and closing. Earlier planning questions may begin elsewhere, while post-closing reporting can move into compliance.
The goal of the Houston Tax Law Firm overview is to help users identify where their matter belongs. Each service page develops one primary search intent in greater depth, while the Home explains how those areas can interact. That structure also helps clients move from a broad concern to the legal team and practice that best match the facts.
