How To Pick the Best Tax Preparation Service

The best tax preparation service depends on how complex your return is, how much help you want and what you're willing to pay. If you have a single W-2 and take the standard deduction, you can likely file free with online software.

If you itemize or run a business, a credentialed preparer may be worth it — the average fee for a professional to prepare an itemized Form 1040 with a state return was about $323 in the most recent National Society of Accountants survey.

Key Takeaways

• Match the service to your complexity. Simple W-2 returns fit DIY software, while business, rental or investment income often calls for a credentialed pro.

• Know the cost range. DIY software runs from free to about $100, while professional preparation can range from roughly $200 to $1,000 or more depending on your forms.

• Free filing exists for many people. IRS Free File offers free guided software to taxpayers with income under about $89,000 for 2025 returns.

• Most people who hire help use paid preparers. Paid preparers completed about 53% of individual income tax returns in 2021.

• Credentials matter. Every paid preparer must have a Preparer Tax Identification Number, and many also hold a CPA or enrolled agent credential.

• Protect your data. Choose services with encryption and multi-factor authentication, since returns contain sensitive personal and financial information.

What Is a Tax Preparation Service?

A tax preparation service helps people and businesses prepare and file returns with the IRS and state tax agencies. The category covers several options:

• Online tax software: Guides you step-by-step through filing.

• Certified tax professionals: CPAs, enrolled agents and tax attorneys who prepare and sign your return.

• Full-service preparation firms: Hand off your documents and a preparer does the work.

• Virtual tax assistance: Software paired with on-demand access to a tax expert.

The IRS processed about 161 million individual income tax returns in fiscal year 2024, and a large share were prepared with professional help.

What Are the Main Types of Tax Preparation Services?

There are several ways to prepare and file. The best fit depends on your financial situation and how comfortable you are filing yourself.

The most recent National Society of Accountants fee survey (2020–2021) put the average cost to prepare a Form 1040 with itemized deductions and a state return at about $323. That survey is the latest the group published, so actual fees today may be higher due to inflation and regional demand.

How Do You Choose the Right Tax Preparation Service?

The right service comes down to a few key factors.

How complex is your tax situation?

Start by gauging how complicated your taxes are. You may benefit from professional help if you:

• Own a business.

• Have investment income.

• Earn freelance or gig income.

• Sold real estate or other large assets.

• File in multiple states.

If your taxes are straightforward — a W-2 job and a few deductions — tax software is often enough. Many people in this group can also use IRS Free File, which provides free guided software to taxpayers with income under about $89,000 for 2025 returns.

What does the service cost?

Cost is one of the biggest deciding factors. Online platforms often offer free filing for simple returns, but added forms and schedules raise the price quickly. Hiring a CPA or enrolled agent costs more but may help identify deductions you would otherwise miss.

Does it offer accuracy guarantees?

Reputable services back their work. Many software companies promise to reimburse penalties or interest if the service makes a calculation error, and professional preparers should review your return carefully before filing.

How does it protect your data?

Tax returns hold sensitive personal and financial information. Look for:

• Multi-factor authentication.

• Data encryption.

• Identity theft protection.

Tax-related identity theft remains a real risk, so security should weigh into your choice.

Can you reach a tax pro when you need one?

Some services include unlimited access to tax professionals, which helps if you have questions about deductions, credits or recent tax law changes. Paid preparers completed about 53% of individual income tax returns in 2021, so plenty of filers value that direct support.

MoneyLion offers a service to help you find personal loan offers. Based on the information you provide, you can get matched with offers for up to $100,000 from our top providers. You can compare rates, terms, and fees from different lenders and choose the best offer for you.

How Can You Tell If a Tax Preparer Is Reputable?

If you go with a professional, confirm they meet basic IRS standards. Look for:

• A valid PTIN. All paid preparers must have a Preparer Tax Identification Number.

• Credentials. A CPA, enrolled agent or tax attorney designation signals training and oversight.

• Transparent pricing. A clear, upfront quote before any work begins.

• Positive reviews. A track record of satisfied clients.

• Year-round availability. Someone you can reach after tax season if questions come up.

Avoid any preparer who promises an unusually large refund or refuses to sign the return they prepared.

What Questions Should You Ask Before Hiring?

A few questions can help you avoid surprises:

• How much experience do you have with returns like mine?

• What is the total cost to file?

• Will you represent me if I'm audited?

• How do you protect my personal data?

When Is a Professional Tax Preparer Worth It?

Professional help tends to pay off when your finances get complicated. Examples include:

• Self-employment income.

• Rental properties.

• Significant investments.

• Recent major life changes, like marriage, a home sale or a new business.

Taxpayers can claim a wide range of credits and deductions depending on eligibility, and a credentialed preparer may help you find ones you'd otherwise miss.
