Langwasser & Company CPAs Secures No-Change Audit


Langwasser & Company, CPAs is dedicated to providing the highest level of service to our clients, no matter the challenge. Internal Revenue Service (IRS) audits can be extremely intimidating and overwhelming to deal with for anyone. So, with that in mind, we are so excited to announce that through our hard work and dedication in representing our client, a $21 million construction company, we were able to obtain the best possible outcome for an IRS audit – a “no change” order. 

“No change” audits result in the originally filed return being accepted by the IRS after the substantiated information has been examined. Aside from receiving the “no change” letter, we are also proud to highlight that we were able to keep the audit from extending into other tax years, saving the client from extra fees and extending the scope and time the audit required. 

Although audits can be an uphill battle, we’d like to thank our loyal client for their cooperation and trust during this examination period.
