Frequently Asked Questions

Answers to Common Tax Service Questions

  • Do you offer tax preparation for both federal and state returns?

    Yes, we prepare both federal and all applicable state returns, including Idaho state taxes. Our CPAs ensure compliance in each jurisdiction and help clients understand how state and federal rules interact. Many of our clients also have multi-state obligations, and we are experienced in navigating those complexities.

  • What do I need to bring to my tax appointment?

    We ask clients to provide common documents such as W-2s, 1099s, last year’s return, and records of deductible expenses. Business owners may also need to bring financial statements and payroll records. To make the process easier, we provide a detailed checklist and secure upload through our client portal.

  • Can you help if I haven’t filed taxes in a few years?

    Yes, we regularly assist clients who need to catch up on prior-year tax filings. Our team will work with you to gather the necessary information, file back taxes, and help reduce potential penalties. We can also coordinate with the IRS on your behalf to create a path forward.

  • How is tax planning different from tax preparation?

    Tax preparation focuses on accurately filing past-year returns, while tax planning looks ahead to minimize your future tax liability. Our CPAs help individuals and businesses create strategies around retirement, investments, business sales, and other events to achieve better long-term outcomes.

  • Do you provide tax services only during tax season?

    No, we offer year-round tax planning and support. While many clients meet us during tax season, our advisory and planning services help individuals and businesses make smarter decisions throughout the year. This ensures fewer surprises and more confidence at filing time.
