Tax Preparation FAQs
Get answers to the most common questions about our tax services.
How much does tax preparation cost?
Individual tax returns start at $350, while business returns range from $800-$2,500 depending on complexity. We provide a transparent quote after reviewing your specific situation. Schedule a free consultation for accurate pricing.
When should I file my tax return?
Tax returns are typically due April 15th each year. However, we recommend filing as early as February once you have all your documents. Early filing means faster refunds and reduced identity theft risk. We can also file extensions if needed.
What documents do I need to provide?
Common documents include: W-2s from employers, 1099s for contract work or investments, mortgage interest statements (1098), property tax receipts, charitable donation receipts, healthcare coverage forms (1095), and prior year returns. We'll provide a comprehensive checklist during your consultation.
Do you handle California state taxes too?
Yes! We prepare both federal and California state returns. California has unique tax laws and credits that we're experts in navigating. We also handle multi-state returns if you worked or lived in multiple states during the year.
Can you help if I'm being audited?
Absolutely. As licensed CPAs, we provide full IRS audit representation. We handle all communication with the IRS, gather necessary documentation, and represent you in meetings. Our goal is to resolve the audit quickly and favorably.
How quickly can I get my refund?
With e-filing and direct deposit, most federal refunds arrive within 21 days. California refunds typically take 2-3 weeks. We file electronically to ensure the fastest processing. You can track your refund status using the IRS Where's My Refund tool.
What if I haven't filed taxes in several years?
We can help you get back into compliance. We specialize in preparing multiple years of back tax returns. The IRS typically allows you to file up to 3 prior years to claim refunds. We'll assess your situation, calculate any penalties, and work on a plan to resolve your tax debt if applicable.
Do I need to visit your office in person?
No! Our services are 100% cloud-based. You can upload documents securely through our client portal and communicate via phone, email, or video call. We serve clients throughout Orange County, Riverside, Los Angeles, and beyond - all virtually. However, we're happy to meet in person if you prefer.
