How We Serve

Audit & Assurance

Audits, Reviews, Compilation & Agreed Upon Procedures

We believe our audit quality and client service is unparalleled, our people can be pleasant to work with, courteous to the company's staff, and operate with any surprises. We believe auditors should be valuable assets to management. We are confident that our quality client service will stand strong when compared to other auditing firms.

Hinkle & Company, PC has provided auditing services for over 20 years. We have intentionally focused our growth on small and manageable groups of high quality clients. This allows us to commit a substantial amount of time and personal service by our top professionals as opposed to sending staff members out with only top professionals arriving at the end of fieldwork.

Industries Served

Governmental Entities

We provide auditing services to cities, counties, school districts and charter schools.  Whether you prepare just annual financial statements or a complete Comprehensive Annual Financial Report (CAFR), we have the experience you want.

College and Universities

We have audit more small to medium-sized colleges and universities in Oklahoma, including their foundation component units, than any other single audit firm over the past five years.

Non-Profit Organizations

We provide audits of public and private foundations, community action agencies, charitable organizations, and other such non-profit organizations.

Single Audits

We provide 'Yellow Book' audits in compliance with Uniform Guidance for recipients of Federal funds. Governmental auditing services may include state and local entities such as cities, authorities, or other political subdivisions, non-profit organizations, or any other organization receiving Federal funds.

Construction Industry

We provide audits or reviews of construction companies needing assurance services for bonding requirements.

Services Provided


Audits are the flag-ship of the services we offer. Auditing services include those in compliance with Yellow Book standards, Uniform Guidance standards, and standard audits in compliance with GAAS.


Reviewed financial statements are a lower level of assurance than audits. The procedures are designed to inquire with management as to whether FASB or GASB guidelines are being followed. Analytic procedures are used to assist these procedures.

Compilations with Full Disclosure

The lowest level of assurance services is a compilation of the financial statements from the records of the entity. These compilations will include the full disclosures required by FASB or GASB accounting pronouncements.

Agreed-Upon Procedures

If you need something other than an audit, review, or compilation we can develop agreed-upon procedures. These types of engagements would include mileage audit of governmental entities, confirmation of receivables or payables, or verification of procedures or controls of internal controls.

Internal Audit Services

We can provide your organization with regular internal audit services designed specifically for your risk areas. Internal audit services are generally provided on a quarterly basis.

Closing General Ledger and Preparing for Audits

If your organization does not have the resources to close the general ledger and prepare for the audit, we can help! We will work as part of your accounting department and prepare all closing entries, prepare work-papers for the auditors, and draft the financial statements and footnotes. We will also work with your auditors during the entire audit process.

Income Tax Services

Individual Income Taxes

Today's tax laws are so complicated that filing a relatively simple return can turn into a headache and a hassle. Even handling your own income tax preparation using a computer software program can be a task that leaves you with more questions than answers.

It is just too easy to overlook deductions and tax credits to which you are entitled to, and nobody likes leaving their hard-earned money on the table. That's why we are here to walk you through every step of this tedious process. We will leave you feeling confident and relieved that you chose to work with us to file an accurate return that allows you to sleep easy.

Hinkle & Company PC

Business Income Taxes

Federal income tax is one of the most challenging and crucial aspects of managing any business of any size. Income tax compliance presents an ongoing risk, one that demands nearly constant monitoring of the regulatory landscape.

Many tax departments devote significant resources to preparing filings and meeting deadlines, often leaving little time for planning, or for managing regulatory changes. We look at compliance beyond the quarterly requirements, assessing tax strategies within the context of a company's overall financial goals.

Regardless of your business structure, we prepare all types of business income tax returns, such as:

  • Form 1120 - Corporate Income Tax Return
  • Form 1120S - 'S' Corporation Income Tax Return
  • Form 1065 - Partnership Income Tax Return​

Other Services

Other Tax Services

We are experienced in various other tax related services outside of yearly preparation of individual income tax returns or business tax returns. They include:

  • Amending returns filed by a prior CPA firm with errors or unreported items
  • Corresponding with the IRS and state tax agencies to resolve issues
Hinkle & Company PC
  • Helping individuals after they have been a victim of identity theft
  • Helping individuals estimate their taxes and calculate quarterly payments to avoid surprises at the time to file
  • Reviewing financials statements of businesses to look for opportunities afforded to them by the tax code
  • Research of specific tax and business issues
  • Foreign bank account reporting
  • Filing of past due returns
  • Staying current on proposed changes to the tax code
  • State-level tax planning

We value a relationship with our clients and view tax services as an ongoing and year-round service, not a service where we prepare your return and talk once a year as many other firms do.

Many planning opportunities are discovered by having a relationship with our clients and understanding their business, industry, and personal situation. We are always available to schedule an appointment to review your latest filed returns and make recommendations to improve your specific situation so that we are taking full advantage of every available credit and deduction.

We do our best to provide an excellent service and experience to relieve any unnecessary pressure or stress created by thinking about your taxes. Please see our contact page to get in touch with us.

We look forward to working with you.
