      Accounting Review from Dmitrii Legetskii

      This company helped us set up our accounting system from beginning to end. I am a serial entrepreneur with experience working with many different accounting groups and this one has been the most responsive overall. They have helped us with registering the business, putting together payroll, and getting our quarterly tax returns filed. They have been also very helpful with giving personal tax advice. I would recommend them to any other friends and especially other business owners.

Frequently Asked Questions

What is the difference between a tax preparation company and a CPA?

The main difference is scope. Tax preparation companies prepare and file returns, while Certified Public Accountants (CPAs) provide deeper financial guidance and long-term tax strategy. 

FactorTax preparation companyCPA
Main rolePrepares and files tax returnsProvides tax and financial expertise
ServicesTax return preparationTax planning, accounting, audits
TrainingVaries by preparerLicensed accounting professional
Complexity handledSimple to moderate tax preparationComplex taxes and business finances
RepresentationLimited ability with tax authoritiesCan represent clients
Typical clientsIndividuals, small businessesBusinesses, high-income individuals

How do tax firms typically charge?

Tax companies usually charge either a flat fee or an hourly rate. Most simple individual returns cost about $200 to $300, while more complex returns often run from $300 to $800. 

Pricing modelTypical costHow it worksBest for
Flat fee$200 to $300 for simple returnsOne set price for the returnSimple personal taxes
Flat fee for complex return$300 to $800Higher fixed price based on forms and complexity Itemized deductions, self-employment, investments 
Hourly rate$100 to $200You pay for the time spent on the workComplex or unclear cases
State return add-on$50 to $150Extra charge for filing state taxes Federal + state filling
Amendment or revision$50 to $300Extra charge to fix or update a filed returnCorrected returns

Tax companies usually raise prices when returns become more complex. Multiple income sources, self-employment, rental property, investments, and business filings all increase the cost. Large firms, CPAs, and firms in high-cost cities also tend to charge more. 

Can tax companies represent me in an audit?

No. Only certain licensed tax professionals can represent you in a tax audit. 

Professional Can represent you in an auditNotes
Certified Public Accountant (CPA) YesFull representation rights before the IRS
Enrolled Agent (EA) YesFederally licensed tax specialist
Tax attorneyYesHandles complex disputes and legal cases
Tax preparation companySometimesOnly if the preparer is a CPA or EA
Unlicensed tax preparerNoCannot represent clients before the IRS

Most tax companies prepare and file tax returns, but cannot represent clients during an audit unless they employ licensed professionals such as CPAs or Enrolled Agents. Only those credentials allow full representation before the IRS. 

Do best tax companies offer Identity Protection (IP) PINs?

No. Tax companies do not issue Identity Protection PINs. 

The IRS issues the Identity Protection PIN directly to taxpayers to prevent tax fraud and identity theft. Tax companies can help you request or manage the PIN during tax filing, but they cannot generate or assign one. 

The PIN is a six-digit code that must be included when filing a tax return. It confirms your identity and prevents someone else from filing a return using your Social Security number. 

What happens if a tax company has a data breach?

Tax preparation companies must report the breach, notify clients, and take steps to stop tax fraud. 

If a tax company experiences a data breach, federal rules require immediate action to protect taxpayer information and prevent fraudulent filings. 

Required actions include: 

  • Report the breach to the IRS to help block fraudulent tax returns linked to stolen taxpayer data. 
  • Notify state tax agencies and law enforcement, such as the FBI or Secret Service. 
  • Inform affected clients that their personal or financial information may be compromised. 
  • Investigate the breach by hiring cybersecurity or forensic experts to identify how the data was accessed and stop further exposure. 

Tax preparation firms must also follow the FTC Safeguards Rule, which requires them to maintain a written security plan that protects taxpayer data.Â
