Jonlyn & Associates Inc, CPA's
Assisting Illinois Business and Individuals in Accounting Tax and Financial Services





684 West Boughton Road Suite 103, Bolingbrook Illinois.

Are you looking for an Illinois Certified Public Accounting firm large enough to offer a full array of wealth management services such as accounting, taxation, financial, and consulting services, but small enough to know you on a personal level? Then look no further. The Wheaton CPA firm of Jonlyn & Associates, started in 1991 by John V. Pezzullo CPA, has grown today to four CPA's and five professional staff accountants, each offering top-notch credentials and experience. From Individual income tax returns to Start-up companies to larger corporations or LLC's, Jonlyn & Associates can assist you with your wealth management, accounting, payroll and income tax requirements, including audits of non-proft 501(c)3 organizations and ERISA 401K profit sharing plans.  And if you are in Internal Revenue Service tax trouble and qualify for an IRS offer in compromise "OIC", we can assist you in saving your tax dollars. Many IRS exams and problems can be resolved quickly without you visiting the internal revenue service.

Whether you need accounting, payroll preparation, tax planning, tax return preparation, small business consulting, or a full complement of other individualized services, we will give you the full resources you would expect only from a large accounting firm while maintaining that personal touch. See why many businesses & professional individuals throughout the DuPage and Will County areas choose Jonlyn & Associates for their accounting, tax, and financial services needs. Jonlyn & Associates directly service the greater Chicago area including Will, Kane, Cook, McHenry, Lake and DuPage County. We also have many out of state and multi state clientèle, both business and individuals.

Our Certified Public Accountants can advise you on the taxability of distributions from your Pension, Keogh, IRA or 401K plan. Individual Retirement Accounts is an excellent way to defer your tax instead of making an immediate donation to the Internal Revenue Service. Our CPA's can help you make the right tax saving decisions.

If your business is unfortunate to incur an employee fraud or theft we can assist you in Forensic Accounting and/or financial audits to determine your loss, employee involvement, and/or where the assets are. Embezzlement is occurring more frequently throughout the business community and much more with the small business. 

We now offer peer reviews of other CPA firms.
