rewrite this title Best Small-Business Tax Services of 2026 – NerdWallet

Small-business tax services range from DIY software to full-service accounting firms (and options between). Which of those services will best serve your needs depends on several key factors.

Many business owners think they can get by with filing their taxes once a year through popular DIY software. Those services may be fine for some businesses, but there’s a solid chance your business is ready for something more intentional.

Many industry professionals suggest that any of the following factors should give you pause to consider moving to expert human help on your small-business taxes.

It’s also important to understand what each of the different services can offer your business.

Ella Rivkin, CEO of ERPS Group, a full-service business advisory firm that offers strategic tax planning, explains that there is a big difference between a professional who files your tax return and one who acts as a strategic advisor. While one keeps your records accurate, the other works to lower your tax bill throughout the year. Having the former doesn’t mean you have the latter.

We’ll dive into that in the next section.

When it comes to hiring a professional to handle your business taxes, the type of credential matters less than specialization and day-to-day focus. Here’s what each option covers and who it’s right for.

Best for: Business owners who want a single point of contact and year-round strategic tax and financial guidance.

Good to know: This is the broadest business tax service option. “A full-size accounting firm with strategic tax planning … they’re doing the bookkeeping, they’re doing the payroll, the sales tax, the tax return, the strategic tax planning, even preferably insurance and wealth management, so they can do absolutely everything in house,” Rivkin says.

🤓 Nerdy tip: This option eliminates the headache of coordinating multiple service providers and ensuring they’re all up to speed on what the other is doing. Not every business will be ready for this option, but it’s worth considering the investment to set up a strong financial ecosystem for your business from the start.

Best for: Business owners who need services beyond taxes, including formal financial statement review for lenders or investors and broader financial advising.

Good to know: CPAs are licensed at the state level and undergo rigorous training and examination, which does in part cover taxation, to earn the credential. They must also complete ongoing education requirements and license renewals. But not all CPAs are well versed in small-business taxes.

🤓 Nerdy tip: Working with a CPA in your state has great advantages. State and local tax obligations vary significantly, and local expertise is valuable.

“ There are a lot of CPAs in this world that are terrible tax people. I fix more CPA mistakes than non-CPAs. CPA does not mean you have any tax experience. ”

Tish Heiss, enrolled agent and founder and CEO of PKH Advisors, PLLC, a Pittsburgh-based tax, accounting and advisory firm serving small businesses, speaks to how important it is to properly vet your chosen tax professional. A CPA may be a great fit for your business. You just need to do your research and ensure they have the tax expertise you require.

Best for: Business owners whose primary need is tax prep, planning and IRS representation.

Good to know: EAs are licensed at the federal level. Unlike CPAs, they are exclusively focused on taxes. While EAs can handle complex business structures (S-corps, partnerships, multi-state), their specialization still varies. So it’s important to ask what entity types they work with regularly.

🤓 Nerdy tip: An EA can be less expensive than a CPA for comparable tax work.

Best for: Sole proprietors and single-member LLCs with simple structures. You’ll want to have clean books, no employees and operate in only one state.

🤓 Nerdy tip: Evaluate these key features when considering a tax software solution:

Expert tip: Rivkin told NerdWallet on the topic of DIY tax software that ultimately the question isn’t whether the software saves you money. It’s really about whether you’re leaving more money on the table — through missed deductions, credits and other savings opportunities — than the cost of hiring a professional.

Focus your search for a business tax professional on the services you need rather than a specific credential. Find someone with demonstrated experience in your business structure and industry. Then interview them before you commit.

Cost estimates below are aggregated from publicly available CPA and tax-firm pricing pages and industry cost guides rather than a single formal survey. Actual fees vary significantly by location, business complexity, bookkeeping quality and the experience level of the professional you hire. Treat these as a general planning range, not a quote.

A note about fees: Tax preparation fees are typically deductible as a business expense on your tax return.

Rivkin offers a helpful analogy for understanding the importance of finding a tax professional who isn’t overwhelmed by a long client list. It’s like going to a doctor who sees “40 patients a day and they only have five minutes to spend with you,” she says. “It’s just not possible to find out everything in five minutes.”

That’s why Rivkin says it’s really important to understand “how much time that professional can give to you because it’s not just putting the numbers together, it’s to actually dig deeper. That’s the only way that they can help you and provide successful results for you.”

Do not hire a tax preparer who does not at least have a PTIN. The IRS requires any person who is paid to prepare federal tax returns to have this ID number. If a paid tax preparer doesn’t have a PTIN, then they are violating IRS rules and subject to penalties. Keep in mind that a PTIN is not a credential that speaks to any sort of formal education or preparation for the job; it simply ticks a legal box.
