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, and ensure that every filing is accurate and submitted on time. 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

Entity Types 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

Schedule C

The simplest business structure, reported on your personal return. We ensure your business income and expenses are properly documented and that you are taking advantage of all available deductions, including the qualified business income deduction.

Starting at $850

Single-Member LLCs

Schedule C or Form 1120

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 $950

Partnerships & Multi-Member LLCs

Form 1065

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 $1,800

S-Corporations

Form 1120-S

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.

Starting at $1,800

C-Corporations

Form 1120

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 $2,000

Non-Profit Organizations

Form 990

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 can save thousands in taxes annually, while the wrong one can create unnecessary complexity and cost. Our Entity Structuring Consultation provides a clear, data-driven recommendation based on your specific revenue, expenses, and long-term goals.

Frequently Asked Questions

Common questions about this service area.

The right entity depends on your specific situation, including your income level, number of owners, liability concerns, and long-term goals. We offer an Entity Structuring Consultation ($500) that provides a detailed analysis of the optimal legal and tax structure for your business. This is a separate engagement from tax preparation and is well worth the investment before you commit to a structure.
An S-Corp election can provide payroll tax savings when your business generates consistent net income above what you would pay yourself as a reasonable salary. The general rule of thumb is that it starts making sense when net business income exceeds $50,000 to $60,000 annually, but the right answer depends on your full financial picture. We can model the savings for you during a planning engagement.
A business tax return includes the preparation and filing of the applicable federal form (Schedule C, Form 1065, Form 1120-S, or Form 1120), K-1 preparation for partners or shareholders, and any required state filings. It does not include bookkeeping, record cleanup, or tax planning, which are separate engagements.
Foreign-owned single-member LLCs are required to file Form 5472 and a pro-forma Form 1120 annually. The penalty for failing to file is $25,000 per form, per year. We handle this filing as part of our Compliance Guard retainer package or as a standalone engagement.
Yes. Sales tax filings are $150 per state per filing period. Quarterly payroll tax returns are $350 per quarter for businesses not on a retainer package. Both services are available as standalone engagements or as part of our monthly retainer packages at a reduced rate.
