“The Moskowitz tax law firm assisted my law firm with applying for the ERC tax credit and performed a miracle as I have next to zero knowledge/skills when it comes to tax returns/forms/refunds. They made it as painless as possible, submitted the necessary documents to the IRS, and then BAM Congress/the President shelved the whole program. They kept me informed, offered encouragement that it would happen, and then over a year (years?) later, they informed me it was processed, approved, and I should receive a check shortly – times 2! And it happened! Thank you Sherri Yee, Paul Vargas, Jaclyn Bull, and all the others (you know who you are!), and of course, Steve Moskowitz. Any future “issues” with the IRS/FTB, I shall return!”
If you are searching for Irvine tax attorneys, it is likely because a tax issue has already begun to escalate—or because you want to prevent one before it becomes more serious. At Moskowitz, LLP, we represent Orange County business owners, professionals, executives, investors, and high-net-worth individuals in complex federal and California tax matters.
Irvine’s financial landscape is shaped by technology, healthcare, real estate, finance, law, construction, professional services, startups, international business, and corporate headquarters. Taxpayers in the area may deal with pass-through income, equity compensation, business deductions, real estate portfolios, contractor classification, sales tax exposure, multiple entities, cryptocurrency, foreign accounts, and income earned across multiple states or countries.
Tax complications like these can lead to inquiries from the IRS, FTB, EDD, CDTFA, or other taxing authorities. What starts as a basic notice or audit may become far more serious if ignored or mishandled, potentially resulting in penalties, liens, levies, garnishments, or criminal exposure.
Moskowitz, LLP assists individuals and businesses with complex tax issues involving:
We believe early action is critical. By reviewing your situation, identifying risks, and managing agency communications, we work to help limit exposure and keep the matter from becoming more difficult to resolve.
Irvine taxpayers with complex financial lives may face heightened stress when the IRS opens an audit. Issues involving privately held businesses, startup stock or options, investment income, real estate interests, professional practice revenue, or significant deductions can lead to substantial exposure if not handled properly. Our team helps evaluate the issues, protect your position, and respond strategically.
We represent C corporations, S corporations, partnerships, LLCs, sole proprietorships, professional practices, and high-income taxpayers in audit matters. For Irvine business owners, physicians, dentists, attorneys, real estate professionals, consultants, contractors, executives, and investors, an audit can reach beyond one year of taxes. It may influence cash flow, business continuity, financing, professional credibility, and future financial planning.
California tax authorities can be equally persistent. The Franchise Tax Board frequently challenges residency positions, capital gains reporting, business income allocation, and multi-state income treatment. These concerns often arise for Irvine taxpayers who leave California, sell companies, exercise stock options, own investments in multiple states, or split their time between jurisdictions.
Our tax professionals create documentation-backed strategies, communicate with tax agencies, and work to move the dispute toward a focused and efficient resolution.
Payroll tax disputes can create immediate and serious consequences for a business. If payroll taxes are not properly withheld or paid, owners, officers, and other responsible parties may face personal exposure in addition to business liability.
Irvine businesses, including startups, professional practices, construction companies, consulting firms, and technology-related companies, may encounter payroll tax scrutiny involving employee versus contractor classification, remote workers, project-based labor, unpaid tax deposits, or the use of independent contractors. These issues can become urgent when the IRS or EDD determines that payroll tax obligations were not met.
Moskowitz, LLP represents companies in IRS payroll tax investigations, EDD audits, worker classification disputes, and trust fund recovery penalty cases. Early response matters because payroll tax problems can disrupt bank accounts, operations, vendor relationships, and the financial survival of the business.
Tax debt can become more difficult to manage the longer it remains unresolved. Irvine taxpayers facing IRS or California tax liabilities may benefit from acting quickly to reduce financial pressure, address disputes, and return to compliance before collection efforts become more aggressive. Our team reviews each client’s financial circumstances and identifies resolution strategies that may be appropriate, including installment agreements, negotiated settlements, penalty relief, offers in compromise, lien assistance, levy concerns, or other tax relief options. Taking action sooner may create more room to negotiate and plan.
Many tax concerns can also be prevented before they become disputes. Through proactive planning, we help Irvine entrepreneurs, executives, investors, business owners, and professionals reduce risk, maintain compliance, and build a stronger foundation for long-term financial stability.
Our team provides guidance on entity structure, compensation planning, business tax compliance, multi-state tax matters, and complex income planning. This type of planning can be especially important for clients with equity compensation, business sales, real estate transactions, investment income, or professional practice earnings.
Tax matters involving alleged fraud, unreported income, delinquent returns, undisclosed foreign assets, or claims of intentional wrongdoing require careful and discreet representation. The consequences can be significant, and both legal and financial risks must be considered.
Moskowitz, LLP represents clients in criminal tax investigations and other high-stakes tax matters. Our goal is to protect your rights, limit unnecessary exposure, and help you understand each stage of the process.
We also help Irvine clients with international tax compliance, including FBAR and FATCA reporting, offshore disclosure matters, foreign bank account concerns, cross-border income, and international business tax issues. For clients with global investments, foreign income, or business interests outside the United States, careful compliance is essential.
Irvine’s economy includes technology, healthcare, real estate, finance, education, construction, professional services, hospitality, retail, international business, and corporate operations. From businesses near Irvine Spectrum Center, John Wayne Airport, and the Irvine Business Complex to offices along Jamboree Road, Main Street, Barranca Parkway, Culver Drive, Alton Parkway, and the I-405 and I-5 corridors, many taxpayers have financial lives that do not fit into simple categories.
A business owner may face payroll tax concerns, sales tax exposure, contractor classification issues, and pass-through income questions. A real estate investor may need help with depreciation, basis, capital gains, rental income, or multi-state holdings. A physician, dentist, attorney, consultant, contractor, or executive may need guidance on deductions, entity structure, payroll compliance, tax debt, or residency planning. An investor may face issues involving stock compensation, capital gains, cryptocurrency, foreign accounts, or an IRS audit.
Moskowitz, LLP provides comprehensive tax support for individuals and businesses facing these kinds of challenges.
You do not have to face a serious tax matter alone. If the IRS, FTB, EDD, CDTFA, or another California tax authority is putting pressure on your finances, business, reputation, or future, Moskowitz, LLP can help. We work with individuals, business owners, professionals, executives, investors, and companies to develop practical strategies for resolving tax problems.
Whether your concern involves an audit, unpaid tax debt, payroll tax exposure, business tax planning, offshore disclosure, tax litigation, or criminal tax defense, our team is prepared to help you understand the path forward.
