A Guide to Small-Business Tax Services

Small-business owners face a widening choice in tax services, from do-it-yourself software to full-service accounting firms, and the right fit hinges on business complexity, revenue, and long-term financial strategy, according to a NerdWallet guide [1]. Industry professionals suggest that businesses with revenue exceeding $50,000, those operating in multiple states, or those that have added employees or changed their legal structure should consider moving beyond DIY software [1]. The Internal Revenue Service, which collected roughly $4.7 trillion in fiscal year 2023, processes more than 271 million returns annually, underscoring the complexity of the U.S. tax system [4]. Certified public accountants are licensed at the state level and undergo rigorous training, but their tax expertise varies. "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," said Tish Heiss, an enrolled agent and founder of PKH Advisors, PLLC [1]. Enrolled agents, by contrast, are federally licensed and focus exclusively on taxes [1]. Ella Rivkin, CEO of ERPS Group, frames the decision as an investment. "The right advisor can save you millions," she said [1]. Rivkin advises business owners to ask how often a professional meets with clients, warning against those who only convene once a year during tax season [1]. For sole proprietors and single-member LLCs with simple structures, software options such as TurboTax Business, H&R Block, TaxSlayer Self-Employed, and TaxAct remain viable, with estimated 2026 costs ranging from $0 to $230 for federal and state filing [1]. Full-service accounting firms, which bundle bookkeeping, payroll, and strategic tax planning, can cost between $1,500 and $6,500 annually [1]. Small businesses form the backbone of the U.S. economy, generating half of all jobs but only 40 percent of GDP, according to data on small and medium enterprises [5]. Globally, SMEs account for 90 percent of all companies and more than 50 percent of employment [5]. The IRS has faced staffing challenges, including a 15 percent reduction in its workforce as of 2018, with enforcement staff declining by more than 25 percent, which has affected its audit capacity [4]. Research published in 2024 found that an additional dollar spent auditing taxpayers above the 90th income percentile yields more than $12 in revenue, while audits of below-median income taxpayers yield $5 [4]. Business owners vetting a preparer should verify credentials through the IRS directory and confirm the preparer holds a valid preparer tax identification number [1]. Red flags include promises of guaranteed refunds, a lack of interest in prior-year returns, and very short meeting times [1].
