Colorado and Denver tax questions
Do you accept new tax clients?
Yes. Centennial Accounting Group is currently accepting new tax clients. Prospective clients can schedule a consultation to discuss their tax situation and determine the appropriate next steps.
Do you provide tax preparation in Denver?
Yes. Centennial Accounting Group provides individual and business tax services for clients throughout Denver, the Denver metro area, and across Colorado.
Do you work with businesses throughout Colorado?
Yes. We provide tax and accounting services to businesses throughout Colorado and can also assist companies with multi-state operations.
Can you handle both my business and personal tax returns?
Yes. We work with both individuals and businesses, and many clients have us handle both. During the consultation we look at your business entity, your personal return, and how they connect, then agree on the right scope.
Do you provide tax planning or only tax preparation?
Both. Depending on your needs, our work can include preparing your returns and proactive tax planning during the year, so decisions are made before filing deadlines rather than after.
Can you help with previous tax years?
Yes. In an initial consultation our team can review prior-year filing needs, unfiled returns, and other outstanding compliance matters, and explain what would be involved in bringing them current.
Can you help if I received an IRS or Colorado tax notice?
Yes. We review IRS and Colorado Department of Revenue notices, explain what they mean, and help you decide how to respond. Every situation is different, so we cannot guarantee a particular result, but you will know your options.
When should I schedule a tax consultation?
Earlier is better. Scheduling well before a filing deadline leaves time to gather documents, plan, and avoid rushed decisions. If a deadline or notice is already close, book now and tell us the date.
