TL;DR
On this page
A newly-solo CPA setting rates for the first time has two reference points and a gap. The first reference is the salary they left behind: $80,000 base plus benefits at a Big 4 firm, billed at $250-400/hr to the firm's clients. The second is the gig-platform aggregate: ZipRecruiter's "Freelance CPA" average sits at $47.71/hr, which is closer to bookkeeping than accounting. Neither is the right anchor for solo practice.
The right anchor is the realized rate after write-downs, collection loss, and the unbillable portion of the working week. This report aggregates the AICPA 2025 National MAP Survey patterns, the National Society of Accountants Income & Fees Survey, the NATP 2026 fee survey, and verified service-tier data from Arvori and SmartPath. The goal is a working rate card for solo practice, not a client-facing cost guide.
The headline numbers
The stated hourly range that recurs across every credible source is $150 to $500 for solo CPA practice, with senior partners at established firms charging $400-800. EAs (enrolled agents) sit at $150-300, a 20-100% discount to CPA rates for equivalent services per SmartAsset's CPA vs EA comparison.
| Credential | Hourly range | Notes |
|---|---|---|
| Senior partner (regional firm) | $400-800 | Often Big 4 alumni; specialist work |
| Solo CPA (experienced, niched) | $300-500 | Tax planning, advisory, IRS rep |
| Solo CPA (core practice) | $150-350 | Standard returns, monthly close, advisory |
| Enrolled Agent (EA) | $150-300 | Tax-focused; IRS practice rights identical to CPAs for representation |
| Unenrolled tax preparer | $75-200 | Implied band; no AICPA or state-board licensure |
Per Accountably, the $150-500 range "varies based on geographic location, complexity of services, level of expertise, and firm size." Per Arvori's 2025 pricing guide, the practitioner-facing distinction is staff-level ($75-150), senior-level ($175-300), manager-level ($250-450), and partner-level ($400-800). Solo practitioners typically anchor at the senior-to-manager band because they're doing the work themselves but pricing it at a level that reflects firm-equivalent expertise.
The billable rate illusion
Most rate guides stop at stated hourly. Solo practitioners need to keep going. Per Arvori's analysis of AICPA MAP Survey patterns, the realized hourly rate is materially lower than the stated rate because three things happen between billing and the bank account:
- Write-downs. Small firms write down 8-15% of billed time as standard practice (clients push back, the engagement scope drifted, the billable hours look excessive in retrospect).
- Collection loss. Even with strong engagement letters, 5-10% of billed work does not collect: late payment, disputed scope, client disappearing.
- Billable utilization. Solo CPAs are billable 55-70% of working time. The remaining 30-45% is admin, business development, training, software setup, and the parts of the practice that do not invoice.
The math compounds. A stated $200/hr at 65% utilization with 12% write-down and 7% collection loss realizes:
$200 × 0.65 × 0.88 × 0.93 = $106.45/hr realized.
That is not a bug. That is the structure of solo practice. The implication: set the stated rate to hit the realized target, not the other way around. A solo CPA targeting $150,000 annual revenue at 1,400 billable hours needs a $107 effective rate, which means a $200-220 stated rate after the realized-to-stated multiplier.
pro tip
The Big 4 exit math. A senior associate at Big 4 earns roughly $80,000-100,000 base while being billed to clients at $250-400/hr. The firm captures the spread to pay overhead, training, partner compensation, and profit. Going solo, you lose the firm's billing leverage and you have to absorb the overhead yourself. The new floor: target a stated rate that gives you a 40-50% margin over your prior loaded employer cost, then iterate up as utilization and demand support.
Service-tier rates (the most-asked questions)
Most solo CPA pricing decisions happen at the engagement level, not the hour level. The tiered rates below come from the verified 2025 corpus across Arvori, SmartPath, and Bonsai, cross-checked against the NSA and NATP surveys.
Tax preparation
| Return type | Range | Notes |
|---|---|---|
| Simple 1040 (W-2 only) | $200-450 (LCOL) / $500-800 (HCOL) | NATP 2026 base average $236 |
| 1040 + Schedule C | $450-900 | Self-employment income adds 2-4 hours |
| 1040 + Schedule E (rental property) | $450-1,200 | Depreciation schedules, passive activity rules |
| S-Corp (1120-S) | $1,500-4,500 | Reasonable comp analysis, K-1 prep |
| Partnership (1065) | $1,200-3,500 | Multi-member LLC, capital account tracking |
| C-Corp (1120) | $2,000-6,500 | Less common for freelance practice |
| Trust/estate (1041) | $1,500-5,000 | Specialty band |
Per CPA Trendlines citing the NATP 2026 fee survey, "the average 1040 base fee jumped from $162 in 2024 to $236 in 2026, a 45.7% nominal increase in two years." The floor is rising fast. A solo CPA pricing 1040s below $200 in 2026 is anchored to pre-2024 numbers.
Bookkeeping and client advisory services (CAS)
| Client size | Monthly retainer |
|---|---|
| Solo freelancer / micro-LLC | $300-500 |
| Small business (under $500K revenue) | $500-1,000 |
| Growing business ($500K-2M) | $1,000-2,500 |
| Mid-market ($2M-10M) | $2,500-6,000 |
| Multi-entity / CFO-advisory | $2,500+/mo per entity |
The CAS retainer market overlaps with bookkeeping practice. The cross-reference is in the bookkeeper rates 2026 complete guide. For CPAs offering CAS specifically, the rate premium over a non-CPA bookkeeper is roughly 30-50% at the same engagement scope because the CPA can sign attestation work and provide tax-planning advisory inside the same retainer.
IRS representation and audit defense
| Engagement type | Range |
|---|---|
| Hourly (IRS examination, appeals) | $200-500+ |
| Flat-fee audit defense (simple) | $2,000-5,000 |
| Flat-fee audit defense (complex) | $5,000-12,500+ |
| Offer in Compromise | $3,500-7,500 |
| Tax court representation | $300-700/hr + retainer |
IRS rep is the highest-margin service line for solo CPAs because it is time-sensitive (client is in active enforcement) and the IRS deadline pressure removes most price negotiation. CPAs and EAs have identical practice rights before the IRS, so the credential premium narrows here. Clients pay for the practitioner's experience with the specific issue, not the letters after the name.
Strategic tax planning and advisory
| Engagement type | Range |
|---|---|
| One-time tax planning (high-income client) | $1,500-5,000 |
| Annual planning package (quarterly check-ins) | $2,500-8,000/yr |
| Business structure / entity selection | $1,500-4,000 |
| Estate planning (basic) | $2,500-8,000 |
Strategic planning is the second-highest-margin service line and the fastest-growing for solo CPAs moving up-market. Per Arvori, the shift from compliance-only practice to advisory is "the most consistent revenue-growth signal" in the AICPA MAP data.
Fractional CFO
| Engagement depth | Monthly retainer |
|---|---|
| Lite (quarterly review + light advisory) | $1,500-2,500 |
| Mid-tier (forecasting, KPI tracking, monthly business review) | $3,000-6,000 |
| Full-service (board prep, fundraising, weekly cadence) | $6,000-12,000+ |
| Hourly rate (when retainer not yet established) | $150-350/hr (entry-mid), $350-500+/hr (senior) |
Fractional CFO is the premium ceiling for solo CPA practice. The engagements are sticky, the work is strategic rather than transactional, and the client base self-selects for size (typically businesses doing $2M+ revenue who need finance leadership but cannot justify a full-time hire).
The billing-method shift
A solo CPA launching practice in 2026 should not default to hourly billing. Per the AICPA 2025 National MAP Survey, the billing-method distribution across firms is:
- Hourly: 63% of firms still use it
- Per-form: 40%
- Value billing: 30% (up 5 percentage points since 2022)
- Fixed pricing: 29% (up 4 percentage points since 2022)
SmartPath's proprietary research across 1,700+ firms found that 79% of firms are actively moving away from hourly for bookkeeping and CAS work. The reasoning is operational: hourly creates a structural misalignment where the faster a practitioner works, the less they earn. Value and fixed billing reward systemization gains.
"Hourly billing is the fastest way to turn your firm into a treadmill."

For new solos: lead with fixed-fee or value-priced packages for recurring work (monthly CAS, annual tax prep), reserve hourly for clearly-scoped specialty engagements (IRS rep, ad-hoc consulting). The bookkeeper engagement letter and proposal template covers the structural mechanics; the conventions transfer directly to CPA engagements.
Tax-season surge pricing
Charging a surcharge for tax-season work, particularly for disorganized clients who submit records late or incomplete, is industry-standard practice, not an exception. Per the National Society of Accountants Income & Fees Survey cited by Intuit's TaxPro Center, 75.1% of tax preparers add a surcharge for disorganized records, averaging $145.14 per affected return.
The surcharge does two things at once. It compensates for the extra hours that disorganized clients consume, and it changes client behavior in subsequent years (the disorganized client either organizes or accepts the price). Solo CPAs publishing the surcharge as a line item in the engagement letter (rather than billing it retroactively as a "complexity adjustment") get materially better client compliance with documentation requests.
Geographic adjustment
Per Arvori's 2025 metro-tier analysis:
| Market tier | Adjustment vs national median |
|---|---|
| Top tier (NYC, SF, Boston, DC) | +40% to +80% |
| Major metro (Chicago, LA, Seattle, Miami) | +15% to +35% |
| Mid-size metro | -5% to +15% |
| Small city / rural | -10% to -25% |
Remote-only practice partially flattens the geographic gap because a solo CPA based in a low-cost market can serve clients in high-cost markets at high-cost-market rates if the client relationship is sticky. The flattening is partial because clients sourcing from local referrals still expect local rates.
Credential and certification premium
The CPA license commands a measurable premium. EAs are competitive for tax-focused practice but cannot perform attestation work (audits, reviews, compilations). The 20-100% range in stated hourly rate compounds over a career:
- A CPA charging $300/hr and an EA charging $200/hr at equivalent utilization
- Across 1,400 billable hours per year
- Produces a $140,000 vs $93,000 stated revenue gap
Net of the CPA license cost (exam fees, CPE, state-board fees, AICPA dues, roughly $1,500-3,000/yr) and the EA license cost (similar but lower, $500-1,500/yr), the credential delta is real money. For a newly-licensed CPA going solo, this is the answer to "should I have just stayed an EA": the data says no.

How to set yours
Working backwards from the verified data, a sensible solo CPA rate-setting process is:
- Calculate your realized-rate target. Decide annual revenue goal. Divide by realistic billable hours (1,200-1,500 for first-year solo). That is your realized hourly rate target.
- Apply the realized-to-stated multiplier. Multiply by 1.7-1.9 to back into stated rate, accounting for 8-15% write-downs, 5-10% collection loss, 55-70% utilization.
- Cross-check against the AICPA MAP band. Senior/manager-level work anchors at $175-450 stated. If your computed rate is well below that band, you are under-pricing.
- Set service-tier flat fees from the table above. Use the realized hourly to compute floor flat fees, then add 15-25% margin for value-pricing.
- Publish the disorganized-client surcharge. $100-200 per affected return, on the engagement letter.
- Lead with fixed-fee packages for recurring work. Hourly is for IRS rep, ad-hoc consulting, and discovery engagements only.
- Add a geographic adjustment. If you are in a top-tier metro or serving top-tier clients remotely, charge for it.
The all-in target for a 3-year experienced, niche-specialized, fractional-CFO-anchor solo CPA is comfortably $400+/hr stated, with realized $200-260. The starting target for a first-year solo CPA leaving Big 4 with no niche yet is $175-225 stated, realized $100-130. Below that band is undercharging.
The honest summary
The published rate ranges for solo CPA practice ($150-500/hr) overstate what hits the bank. The realized rate after write-downs, collection loss, and unbillable time is roughly 50-65% of the stated rate. Set the stated rate to clear the realized target, lead with fixed-fee and value-priced packages, publish the disorganized-client surcharge, and exit hourly for everything except specialty engagements.
The cross-profession context is in the freelance rates 2026 complete guide. The bookkeeping-side data is in the bookkeeper rates 2026 complete guide. The lien doctrine when clients do not pay is in the bookkeeper late payment and accountant's lien post, and applies identically to CPA practice.
