Q3 estimated tax and extended 2025 partnership & S-corp returns are due in 36 days — September 15, 2026. Start now

Everything a small business and its owner need — except the things that need a licence.

Returns, books, payroll, planning and the letters that arrive afterwards. Each service is priced separately and flat, so you can take one thing or the lot without being bundled into something you did not ask for.

Being straight with you

What we do not do.

A short, honest list is worth more than a long, vague one. If you need any of the following, you need a differently licensed professional and we will say so at the first conversation rather than after taking a fee.

  • Audits, reviews and compilations. Any attest or assurance engagement requires a licensed CPA firm. We are not one. We prepare financial statements for your internal management use only.
  • Legal advice or legal drafting. Operating agreements, contracts, trusts and entity formation as a legal matter belong with an attorney.
  • Investment or insurance advice. We are not investment advisers and we sell no financial products. Nothing we recommend pays us a commission, because nothing we recommend could.
  • General representation before the IRS. An unenrolled preparer’s practice rights are narrow and specific. We explain exactly what they cover on the IRS notice help page.

What is left is a great deal: preparing and filing returns, keeping books, running payroll, planning ahead, and answering the correspondence that follows. That work does not require a CPA licence, and it is the work we do all day.

Xelvon Tax Advisors LLC is not a certified public accounting firm and is not a law firm. We are not certified public accountants, attorneys or enrolled agents, and we are not licensed by the Utah Board of Accountancy or any state board of accountancy. We do not provide audit, review, compilation, attest or assurance services, and we do not provide legal or investment advice. We do not have authority to represent clients before the Internal Revenue Service. We can prepare and explain a written response for you to sign and send yourself, and we will refer you to a certified public accountant, an enrolled agent or a tax attorney when a matter needs one.

Preparing and e-filing federal and state tax returns, keeping books, running payroll, filing information returns and planning ahead do not require a CPA licence — that is the work we do. Read the full scope of practice.

Where we can and cannot work. We prepare federal returns for taxpayers anywhere in the United States, and state returns for every state except those listed here. A small number of states license or register tax return preparers, and we do not offer services there until our registration is in place. We cannot currently prepare any returns for residents of Connecticut and New York, where a state preparer registration is required before a firm may prepare returns or advertise. We cannot currently prepare individual income tax returns for residents of Maryland and Oregon; business and fiduciary returns for those states are outside that restriction. If you live in one of these states, call (435) 341-4014 and we will tell you exactly where our registration stands rather than take work we cannot do.
