Effective tax planning is not a once-a-year activity — it is a year-round strategy that determines how much of your income you keep. O&M Tax & Business Advisory builds proactive tax plans for Edinburg and Rio Grande Valley small business owners that go far beyond simple return preparation. Services include estimated tax planning, deduction optimization, entity structure review, payroll tax strategy, and retirement contribution planning — all designed to legally minimize what you owe and maximize what you keep. Whether you are a sole proprietor, LLC owner, or S-Corp, O&M Tax creates a custom plan matched to your income level, industry, and financial goals.
Your current tax professional only hears from you in March or April. By then, the biggest savings opportunities have already passed. Tax strategy must happen in January, June, and October — not just at filing time.
Many South Texas business owners are operating as sole proprietors when they should be structured as S-Corps. That one mistake alone can cost $10,000–$30,000 in unnecessary self-employment taxes every single year.
Home office deductions, vehicle expenses, retirement contributions, and Qualified Business Income (QBI) deductions — most business owners miss these because their advisor never brought them up.
Without clean monthly bookkeeping, you’re making major decisions — hiring, buying equipment, expanding — without the financial data to back them up confidently.
Staffing, software, insurance — costs keep rising, and without a financial system in place, profitability quietly erodes year after year.
The first step is free. Schedule your strategy call and know within 45 minutes exactly how much you’ve been overpaying — and what you can do about it.
