Tax Clients
As a valued member of the PBMares community, we want your experience to be predictable and easy. Whether you’re working with us on your business or individual tax returns, you’ll find helpful links and resources here.
Below are links to help you prepare for your 2024 tax filing. Please contact PBMares if you need additional assistance.
Client Responsibilities
As a valued client, we want you to be an active participant in your tax filing process! It helps to understand how the process works.
Preparing a tax return involves organizing and assembling several documents, many of which come from third parties. We understand that gaining access to some documents and tax forms, like K-1s, takes time and is out of your control. While you may not have everything ready to send to us at one time, please do not wait to send a critical mass of documents when only one or two may be missing. This helps us to complete your return faster and assign work accordingly.
In some cases, extending your tax return may be necessary. Extensions are common and do not increase the likelihood of an IRS audit; however, if you owe taxes, extending the return is not an extension of time to pay any taxes due. If your return is extended, PBMares will help you understand your tax liability and any extension payments that need to be made.
In general, as a tax client, you are responsible for:
- Signing the Engagement Letter and disclosure statement
- Updating personal information in the Tax Organizer
- Answering all questions in the Tax Organizer
- Submitting all tax and related documentation to PBMares as soon as possible
- Ensuring the accuracy and correctness of the information provided to PBMares
- Reviewing and approving the return in a timely manner
For a specific list of your unique client responsibilities, please refer to your most recent Tax Engagement Letter.
