About
Built on trust,
not volume.
There are firms that process thousands of returns a season. This is not one of them, and that is deliberate.
The firm
OLEKC Tax and Accounting Services LLC is a tax preparation and accounting firm serving individuals and small businesses across the Chicago metropolitan area. Founded and run by Oleksiy, who brings over four years of hands-on experience in tax and accounting, the firm holds an active PTIN and EFIN and is an Authorized IRS e-file Provider.
The practice started with tax returns and grew into year-round work: monthly bookkeeping, payroll, business formation, and planning. That change was deliberate. A tax preparer who only sees you in March cannot help you make decisions in September, when the decisions actually get made.
When you work with OLEKC you get a direct line to the person actually doing your work. Not a call center, not a rotating cast of seasonal staff, and not a different name on your file every year.
