Between January and April 2026, our research team analyzed publicly disclosed pricing data from 45 CPA and tax preparation firms across five U.S. regions. Our analysis found that a simple Schedule C sole proprietorship averages $640 nationwide, while S-Corporation and partnership returns typically range from $850 to $1,300.
Key Takeaways
- Business structure and annual revenue remain the primary drivers of small business tax preparation costs.
- The Northeast region of the US continues to carry the highest average small business tax preparation fees.
- Fewer than 50% of CPA firms publicly post price lists.
- The biggest cost drivers are business complexity, return timing, and record organization.
Calculation Methodology
We calculated regional averages using the midpoint of published price ranges from three firms in each of three cities per region. National pricing ranges were determined by identifying the lowest and highest disclosed fees, excluding extreme outliers beyond two standard deviations.
Average Small Business Tax Preparation Costs by Entity Type
Entity type is the single strongest cost driver in small business tax prep. Once a company crosses $500K in revenue, the preparation process demands more documentation, compliance checks, and billable time, regardless of whether the entity type changes.
The Average Small Business Tax Preparation Costs by Entity Type: 2026
| Entity Type | Revenue Under $250K | Revenue $250K-$500K | Revenue $500K-$1M | Revenue $1M-$2M |
| Schedule C (Sole Proprietor) | $475 – $900 | $700 – $1,200 | $900 – $1,450 | $1,200 – $1,800 |
| Partnership | $950 – $1,500 | $1,300 – $1,950 | $1,700 – $2,600 | $2,400 – $3,500 |
| S Corporation | $1,300 – $2,050 | $1,800 – $2,800 | $2,450 – $3,650 | $3,250 – $4,800 |
| C Corporation | $1,600 – $2,500 | $2,250 – $3,450 | $3,000 – $4,500 | $4,000 – $6,000 |
Key Findings:
- S-Corporation costs exceeded partnership fees by an average of 15% across all revenue tiers, widening significantly above $500K.
- C-Corporations in the $1M–$2M range showed the widest cost spread ($4,000–$6,000), driven by variation in recordkeeping quality and multi-entity complexity.
- Fees across all entity types are estimated to increase 6–8% from 2025 to 2026, a trend expected to continue through 2027.
Small Business Tax Preparation Cost Trends: 2023–2026
Per the NATP 2025 Fee Study, 83% of tax professionals raise fees every one to two years, typically by 6–10%. The table below applies the lower bound of that range (6% annually) to compile a four-year trend view from our 2026 baseline data. These figures represent the national average midpoint for each entity type at revenue under $250K.
The Average Small Business Tax Preparation Cost Trend by Entity Type: 2023-2026
| Entity Type | 2023 Avg. | 2024 Avg. | 2025 Avg. | 2026 Avg. |
| Schedule C | $579 | $614 | $651 | $688 |
| Partnership | $1,058 | $1,121 | $1,189 | $1,225 |
| S Corporation | $1,500 | $1,590 | $1,625 | $1,675 |
| C Corporation | $1,783 | $1,890 | $2,003 | $2,050 |
Note: Figures represent midpoints extrapolated at 6% annually from 2026 baseline data. Actual increases at individual firms may vary.
Key Findings:
- Average costs across all entity types rose 12–19% from 2023 to 2026.
- Business owners who didn’t renegotiate CPA terms during this period likely absorbed $100–$300 in added costs with no change in service scope.
- Fee growth is projected to continue at 6–8% annually through 2027.
Regional Cost Comparison Analysis
Geography has a measurable impact on tax prep pricing even for identical business profiles. The Northeast commands a 35% premium over the national average; the Midwest runs 25% below it.
Regional Tax Preparation Cost Comparison: 2026
| Region | Schedule C Average | S-Corp Average | Partnership Average | Premium vs National | Most Affordable City |
| Northeast | $650 – $1,600 | $1,300 – $2,200 | $1,200 – $2,200 | +35% | Philadelphia, PA |
| Southeast | $375 – $1,100 | $850 – $1,300 | $850 – $1,300 | -5% | Charlotte, NC |
| Midwest | $425 – $850 | $780 – $1,300 | $780 – $1,300 | -25% | Minneapolis, MN |
| Southwest | $530 – $1,100 | $900 – $1,600 | $900 – $1,600 | National Average % | Phoenix, AZ |
| West | $425 – $850 | $850 – $1,600 | $850 – $1,600 | +10% | Denver, CO |
Key Findings:
- The Northeast’s 35% premium is driven by higher CPA operating costs, market density, and more complex client profiles.
- The most affordable large markets (Minneapolis, Charlotte) run 30–40% below the most expensive (Boston, New York).
- Remote CPA services are gradually compressing regional gaps, a trend expected to accelerate through 2027.
Industry Transparency and Pricing Models
Roughly two-thirds of CPA firms require a consultation before disclosing fees. Only 22% post detailed fee schedules online, concentrated in the Southeast and Midwest.
CPA Pricing Model Breakdown: 2026
| Pricing Model | Firms Using Model | Transparency Level | Average Cost Range | Geographic Concentration |
| Published Fee Schedule | 22% | High | $135 – $1,600 | Southeast/Midwest |
| Consultation Required | 63% | Low | $500 – $2,700 | Northeast/West |
| Monthly Retainer | 15% | Medium | $200 – $4,750/month | West Coast |
| Hourly Billing | 25% | Medium | $100 – $550/hour | All Regions |
| Value-Based Pricing | 10% | Low | Project-dependent | Major Metro Areas |
Note: Percentages exceed 100%; firms may use multiple pricing models simultaneously.
Key Findings:
- The 63% consultation-required model creates an information disadvantage for business owners shopping on price.
- Pricing transparency is highest in the most competitive regions, suggesting it functions as a differentiator rather than an industry norm.
- Monthly retainer models show the widest cost spread ($200–$4,750/month), reflecting wide variation in what’s included.
Cost Factor Impact Assessment
Disorganized recordkeeping is the most common and preventable cost driver, affecting 40% of clients. Multi-state operations affect fewer businesses but carry the highest impact.
Tax Preparation Cost Factor Impact: 2026
| Cost Factor | Average Impact | Range | Frequency | Mitigation Strategy |
| Disorganized Records | +$185 | $75 – $450 | 40% of clients | Monthly bookkeeping |
| Rush Filing (Last 30 Days) | +20% | 15 – 30% | 25% of clients | Early preparation |
| Multi-State Operations | +400% | 200 – 600% | 15% of clients | State tax planning |
| First-Year Client | +25% | 10 – 40% | 30% of clients | Prior year analysis |
| Complex Deductions | +$225 | $100 – $550 | 35% of clients | Quarterly reviews |
| Prior Year Amendments | +$375 | $200 – $800 | 10% of clients | Accurate initial filing |
Key Findings:
- Disorganized records affect more clients than any other factor, and are entirely preventable with monthly bookkeeping.
- Multi-state operations add an average of 400%, and the cost curve steepens with each additional jurisdiction.
- A first-year S-Corporation client who rushes filing with disorganized records could face a 60–70% surcharge above the base rate.
