What types of business tax returns do you prepare?

We prepare all business entity tax returns including Form 1120 (C-Corp), Form 1120S (S-Corp), Form 1065 (Partnership), Schedule C (Sole Proprietor), and multi-member LLC returns. We also handle franchise tax reports, sales tax filings, and payroll tax returns for Texas businesses.

How much does business tax preparation cost?

Our business tax preparation starts at $750 for simple Schedule C filings and ranges up to $3,500+ for complex multi-state corporate returns. After our initial consultation, we provide a transparent quote based on your specific entity type, number of transactions, and complexity. There are never hidden fees.

When are business tax returns due?

It depends on your entity type. Partnerships and S-Corps are due March 15th, while C-Corps and sole proprietors (Schedule C) are due April 15th. We can file extensions if needed, giving you until September 15th or October 15th respectively. Texas franchise tax reports are due May 15th annually.

Should my business be an LLC or S-Corp?

The right entity depends on your income level, business type, and growth plans. Generally, S-Corps can save on self-employment taxes once your net income exceeds $60,000, but LLCs offer more flexibility. We provide entity selection consulting to analyze your specific situation and can help you convert if beneficial.

What business expenses can I deduct?

Common deductions include office rent, equipment, supplies, professional services, insurance, travel, meals (50% deductible), home office expenses, vehicle costs, and employee wages. We review your expenses to ensure you're capturing all legitimate deductions while maintaining proper documentation.

Do you provide year-round support or just at tax time?

We provide comprehensive year-round support including quarterly tax planning sessions, estimated tax calculations, quick questions via email or phone, and proactive tax-saving recommendations. You work with the same team throughout the year, not just during tax season.

S-Corporation Tax FAQs

Common questions about S-Corp taxation and our services

When should I elect S-Corp status?

Generally, when your net business income exceeds $60,000-$80,000 annually, S-Corp election becomes beneficial. The exact threshold depends on your specific situation. We provide a free analysis to determine your optimal timing.

What is reasonable salary for S-Corp owners?

Reasonable salary varies by industry, experience, and duties performed. Generally, it should reflect what you'd pay someone else to do your job. We use IRS-approved methods to determine and document your reasonable salary.

Can I elect S-Corp status mid-year?

Yes, but it complicates your tax filings. You'll need to file two returns for the year - one as an LLC/sole prop and one as an S-Corp. We typically recommend January 1st elections for simplicity.

What's the deadline for S-Corp election?

Form 2553 must be filed by March 15th to be effective for the current tax year. However, late election relief is available in many cases. We can help with both timely and late elections.

Do all states recognize S-Corp elections?

Most states recognize federal S-Corp elections, but some like California, New York, and New Jersey have additional requirements or taxes. We handle multi-state compliance for S-Corps operating nationwide.

How much can I save with S-Corp status?

Savings typically range from $5,000 to $50,000+ annually, depending on income level. The primary savings come from reduced self-employment tax. Our free analysis calculates your specific savings potential.
