David E. Clampitt is a solo CPA practice in Oklahoma City focused on individual income tax preparation, small-business accounting, and tax planning for self-employed professionals. Unlike larger multi-partner firms, Clampitt handles clients directly rather than routing them through junior staff, a structure that appeals to business owners and freelancers who prefer consistency and direct access to the person doing the work.
As a sole practitioner, Clampitt operates at a smaller scale than regional firms like Crowe LLP or national chains like Jackson Hewitt, but with different economics: no overhead for multiple offices or large administrative teams means lower fees for clients and, typically, longer relationships with the same accountant. The practice centers on preparing Form 1040 returns with schedules for self-employment income, rental property, and investment accounts. For business clients, Clampitt prepares entity returns (S-corps, partnerships, sole proprietorships) and provides quarterly estimated tax guidance, year-end tax planning to reduce liability, and bookkeeping support.
Clampitt charges by the complexity of the return, not a flat rate. A straightforward individual return with W-2 income and standard deductions typically runs $150 to $250. Returns with rental properties, business income, or multiple investment accounts add $75 to $150 per schedule. Small-business returns start around $300 and scale with entity type and transaction volume. Quarterly tax planning consultations are generally billed hourly at rates between $150 and $200 per hour, though an initial consultation may be shorter and less costly. Call to confirm current fees, as rates shift seasonally; tax prep pricing often increases between January and March.
Oklahoma City has three broad tiers of tax services. Large regional firms like Crowe or BPM Accounting serve primarily mid-market and corporate clients and charge accordingly, with business returns starting at $1,000 or more. Mid-sized local firms like Brickhouse Accounting and CliftonLarsonAllen offer similar depth but higher overhead. Solo practitioners like Clampitt suit business owners and self-employed individuals who want direct access to one accountant, lower fees, and personal service without paying for unused infrastructure. Storefront chains like H&R Block and Jackson Hewitt are cheapest for simple returns (sometimes under $100) but do not offer tax planning or ongoing advisory relationships. Clampitt falls between: more involved than a chain, more accessible and cheaper than a large firm, with continuity that few other options match in Oklahoma City.
Clampitt suits self-employed consultants, small-business owners with straightforward structures, rental-property investors, and professionals with side income who value direct accountability and ongoing tax strategy. The solo model means you work with the same person year to year, which builds context and reduces the chance of missed deductions or filing errors. It does not suit large corporations or entities with complex M&A, multi-state operations, or international exposure; those clients need the resources and specialized teams that bigger firms provide. It also may not be ideal if you prefer a one-call-a-year transactional relationship; Clampitt's model emphasizes planning and follow-up.
A new client typically starts with a phone or in-person consultation to review the prior year's return, current business structure, and income sources. Clampitt will ask for prior tax returns, business records, W-2s, 1099s, and any major changes in income or deductions. If it is a business client, he may request bank statements and profit-and-loss summaries. The conversation establishes what tax strategies are available (retirement contributions, entity structure, timing of income) and what documents you need to gather before preparation begins. The goal is to flag opportunities before filing, not after.
Clampitt operates by appointment. Tax season (January through April 15) requires scheduling weeks in advance; summer and fall are more flexible. Exact hours and contact information are best confirmed by calling directly or checking a local business directory, as these details vary year to year. Most work can be handled by mail, email, or secure file transfer, though meeting in person at his Oklahoma City office is an option if you prefer it.
David E. Clampitt fills a specific role in Oklahoma City's accounting landscape: for business owners and self-employed professionals who want lower costs and direct access to their CPA, without the overhead of a larger firm, a solo practice delivers both.
