Taking on new clients?

We receive many new inquiries from taxpayers seeking an Enrolled Agent and would like to refer them to members building their practices.

We also receive regular contacts from seasoned tax practitioners looking to retire, seeking other like-minded tax professionals they can trust to refer their valuable clients to.

As such, we are developing a list of members taking on new clients. If you want to be added to this list, please reach out to [email protected] and specify the type(s) of taxpayer(s) you are most interested in serving.

CoSEA continues to work closely with Our State Agencies and Legislators

CoSEA is working with CDOR and CDLE to develop future rules and regulations and to become an apprenticeship sponsor for our members. If you are interested in participating in this process, please email me today at [email protected] or call John Dundon on his cell at 720-234-1177.

For next year's 77th General Assembly, CoSEA is working on legislation to give business owners who are in arrears on sales or withholding taxes an opportunity to enter into an installment agreement rather than face bankruptcy or closure. Please join us in this most excellent effort.

Trump Accounts:

Treasury, IRS issue proposed regulations on employer contributions to Trump Accounts under the Working Families Tax Cuts

IR-2026-90, Aug. 11, 2026 — The Department of the Treasury and the Internal Revenue Service today issued proposed regulations providing guidance to employers that choose to make contributions to Trump Accounts for employees or their dependents.

Treasury and the #IRS remind you about the new Trump Account, a long-term savings tool for eligible children that lets your investment earnings grow tax deferred. Employers can contribute up to $2,500 per year, within the total annual contribution limit of $5,000. Learn more: https://ow.ly/HWuC50ZyE3h

Running a business and looking for a recruitment or retention boost? The Trump Account is a great incentive for current and future employees who have or plan to have children. Employers can contribute up to $2,500 per year for eligible children. https://ow.ly/HWuC50ZyE3h

See Understanding Trump Accounts and a one page explanation about Trump Accounts.  Many employers have been waiting for more guidance on employer contributions to Trump Accounts to administer their plans. You can submit comments until September 25, 2026.
