Business Tax & Compliance
Your business return prepared by an Enrolled Agent firm, not a seasonal storefront or a DIY app: Schedule C, S-corp and partnership returns, multi-state filings, and the documentation that holds up if the IRS asks. You get a clear scope and a fixed fee before we start.
Sending a request is free and carries no commitment. Scope and fee are confirmed in writing.
In short: We prepare business tax returns for LLCs, S-Corps, C-Corps, and partnerships starting at $850, with a written scope and fee before work begins. The firm is led by an Enrolled Agent authorized to represent businesses before the IRS, and serves clients in all 50 states remotely.

Business Tax Preparation Built on Accuracy and Structure
Running a business means managing a constant stream of compliance obligations. Federal and state tax returns, quarterly estimated payments, payroll filings, sales tax, and annual reports all demand attention, and the consequences of getting them wrong range from penalties to lost opportunities.
At Arc & Ledger, we approach business tax preparation as a structured engagement with a defined scope. We review your financial records, prepare the applicable returns under written procedures, and give each return a second review before it is filed. If your books need attention before we can prepare your return, we will tell you upfront and scope that work separately.
We work with businesses across a range of entity types and industries. Whether you operate as a sole proprietor, a single-member LLC, a partnership, or a corporation, we understand the specific forms, elections, and compliance requirements that apply to your structure.
What Is Included
- Review of financial records and prior year returns
- Preparation and e-filing of applicable federal business return
- K-1 preparation for partners and shareholders
- State business return preparation
- Quarterly estimated tax payment calculations
- Compliance calendar for upcoming filing deadlines
- Post-filing support for IRS or state correspondence
Which Business Entity Types Do We Serve?
Each business structure has distinct tax obligations. We prepare returns for all common entity types and can advise on whether your current structure still serves your goals.
Sole Proprietors
The simplest business structure, reported on your personal return. We check that your business income and expenses are properly documented and that you claim the deductions you qualify for, including the qualified business income deduction.
Starting at $850
Single-Member LLCs
Domestic-owned SMLLCs file on Schedule C unless they have elected corporate treatment. Foreign-owned SMLLCs have additional reporting requirements, including Form 5472, which carries a $25,000 penalty for non-filing.
Starting at $850
Partnerships & Multi-Member LLCs
Partnerships file an informational return and issue K-1s to each partner. We prepare the partnership return and all associated K-1 schedules, ensuring proper allocation of income, deductions, and credits among partners.
Starting at $1,595
S-Corporations
S-Corps pass income through to shareholders while providing potential payroll tax savings. We prepare the corporate return, K-1s, and coordinate with your payroll provider to ensure reasonable compensation compliance. The starting fee includes your California return and a reasonable-compensation memo (a $495 value).
Starting at $1,595
C-Corporations
C-Corps are taxed at the entity level and face unique considerations around retained earnings, dividends, and accumulated earnings tax. We prepare the corporate return and advise on distribution strategies.
Starting at $1,895
Non-Profit Organizations
Non-profits have specific reporting requirements to maintain their tax-exempt status. We prepare the annual information return and ensure compliance with public disclosure and governance requirements.
Starting at $1,500

Not Sure Which Entity Structure Is Right for You?
Choosing between an LLC, S-Corp, or C-Corp is one of the most consequential decisions a business owner makes. The right structure depends on profit, payroll, state, and plans for the business; the wrong one adds cost and paperwork without a matching tax benefit. Our Entity Structuring Consultation provides a written recommendation based on your specific revenue, expenses, and long-term goals.
