So You Can Focus On Growing Your Business

Maybe this has happened to you


You know your periodic tax filings are coming due or maybe that the due date has passed so you call your accountant to get things moving.

You leave a message.

A couple of days later, you look through the mountainous pile of paperwork on your desk, and you see something that confuses you on last month’s Profit & Loss statement. Mentally, you add that to the list of things you need to ask your accountant. And so you won’t forget, you send him an email.

Another week goes by.

You get an invoice in the mail from your accountant but it doesn’t seem quite right, so you want to ask for some clarification and he still hasn’t called you. And in the same stack of mail, you see an envelope from your “friends” at the Department of Revenue.

You send your CPA another email and leave another voicemail.

With some trepidation, you reach for the letter opener, afraid of what you’ll find in that envelope.

  • This doesn’t happen to clients of Mueller Tax & Accounting Services. Whether it’s a simple question about last month’s P&L, or a discussion about long-term tax planning or anything else related to your firm’s tax and financial needs we want to talk to you!
  • We return your calls promptly.
  • We answer your emails.
  • We respond & we’re here when you need us!


Or, maybe you’ve had this kind of experience


You finally get that call back from your accountant. Relief! You tell him you’re in the middle of something (what business owner isn’t always in the middle of something?) but you can take a few minutes, because you really need to talk to him.

Ninety minutes (and six missed customer calls) later, you finally disconnect. Your face is red, and your blood pressure is probably a bit on the high side.

You’re embarrassed, ashamed of yourself (despite your many accomplishments) you feel awful!

You’ve just spent an hour and a half receiving a verbal spanking and a first-class scolding from your accountant.

Your tax filings are late, your bookkeeping is sloppy (wasn’t he supposed to help you fix that?) and he’s going to have to add a late fee to your invoice for his ‘services.’

You’re a bad client!

As you head to the break room for a fresh cup of coffee (and a deep breath or two), you realize your accountant never did answer the questions you’d called him about.

Nope, no answers just the rebuke.

  • This is another thing Mueller clients never experience. We’re here to help you! Some CPA firms treat you like you and your business exist to help them and that’s completely the opposite of the attitude we take at Mueller Accounting & Tax Services.
  • We appreciate what you’re going through.
  • We know how easy it is for any business owner to get upside-down with the IRS, or fall behind on bookkeeping chores.
  • At Mueller Accounting & Tax Services, whatever the issue with your tax or accounting situation, we respond with a positive mindset and expectation. Whatever it is working together, we’ll get this done.

Our business taxes are now being done correctly after almost 7 years of huge mistakes by other CPAs!

Thank You Mueller Accounting & Tax Services

for making our business better and getting us on the right track!
