FAQs
Normally, you will need your W-2s, 1099s, bank statements, dependent information, expense receipts (business, education, medical, etc.), and your prior-year tax return. Contact us and we will send you a detailed list of requirements.
You can check the status of your federal refund using the IRS “Where’s My Refund?” tool, available at IRS.gov or through the IRS2Go app. You only need your SSN/ITIN, filing status, and the exact refund amount.
For your state refund, you can use the “Where’s My Refund?” system from the Minnesota Department of Revenue on its website. It will ask for your SSN/ITIN, date of birth, type of return, and refund amount.
At CBO Accounting & Advisory Services, we offer tax preparation services in English and Spanish for individuals and small businesses in Minneapolis and the surrounding metropolitan area. We review deductions, credits, and deadlines for both the IRS and the state of Minnesota.
Do not be alarmed. Bring us the letter immediately. We will review it and explain what it means and what the next steps are. We offer support for the returns we prepare. We can also amend prior-year returns if errors are identified.
For most people, the deadline is mid-April (the same date for the IRS and Minnesota). If you request an extension, you can usually file until October, but any payment due is still required in April. During your appointment, we review your case and remind you of all important deadlines.
Filing late may result in penalties and interest, but the sooner you address it, the lower the cost. We help you get back on track with the IRS and Minnesota, set up payment plans, and correct prior-year returns if needed.
