Federal and State Tax Filing

ARNA prepares and files all required U.S. federal and state tax returns. We handle individual returns (Form 1040 and schedules) for residents, self-employed professionals, and partnerships, as well as business returns (Forms 1120, 1120-S, 1065) for corporations, S-Corps, LLCs, and partnerships. Our experts also prepare estate, and trust returns (Form 1041) when needed. We carefully account for multi-state requirements: since taxpayers must file a return in every state where they earn income, we manage each state return and related withholding or estimated payments.

    Our service includes:

  • Federal income tax returns for individuals, estates, trusts, and businesses (Forms 1040, 1120, 1120-S, 1065, etc.).
  • State income tax returns in all applicable states (we ensure compliance wherever you have tax nexus).
  • Payroll and sales tax filings (if needed) in coordination with tax strategy.
  • Quarterly estimated tax payments and extensions to avoid penalties.
  • Accurate computation of deductions and credits to reduce your tax bill.

    This end-to-end approach means ARNA keeps track of deadlines and details, so you don’t have to, ensuring all federal and state filings are accurate and timely.

In case of an audit, our CPAs gather and organize crucial records, communicate directly with IRS agents, and provide strategic advice on addressing any findings.

    Our audit support services include:

  • Audit representation
  • Notice and inquiry response
  • Penalty relief

    By maintaining rigorous compliance and offering expert support, ARNA ensures that if the IRS ever comes calling, you’re fully prepared and represented.

International Tax Advisory (Cross-Border Compliance)

Whether you have U.S. tax obligations abroad or foreign income in the U.S., we provide tailored advisory and compliance services. Our offerings include expatriate tax returns, foreign business structuring, and global tax planning. We address both “outbound” scenarios (U.S. individuals or companies operating internationally) and “inbound” scenarios (foreign nationals or entities with U.S. tax exposure), focusing on minimizing worldwide tax liability.

    Key services include:

  • Expatriate and foreign national compliance
  • Cross-border planning
  • International tax treaties

    With ARNA’s global perspective, you can expand or operate internationally with confidence that both U.S. and foreign tax rules are being met.

Tax Planning Strategies for Individuals and Businesses

Proactive tax planning is a core part of ARNA’s services. We work year-round to develop strategies that lower your future tax bills while aligning with your financial goals. For individuals, we analyse income, investments, retirement contributions, and life changes to maximize deductions and credits. For businesses, we consider entity structure, timing of income and expenses, capital purchases, and available incentives. Proper tax planning not only ensures legal compliance, it also maximizes deductions and optimizes your financial position.

    Our tax planning services include:

  • Year-round projections
  • Deductions and credits
  • Retirement and estate planning
  • Business structure optimization
  • Succession and growth strategy

    Our advisors stay up to date on the latest tax law changes so your plans adapt over time. By integrating planning with filings, we help you keep more of what you earn

Corporate Tax Return Preparation (C-Corp, S-Corp, LLCs)

ARNA prepares complete tax returns for all types of business entities. We understand the distinctions between C corporations, S corporations, and LLCs and file the correct forms for each. For C corporations, we prepare Form 1120 and state corporate returns, calculating corporate tax at federal and state levels. Distributed profits (dividends) are then taxed at the shareholder level, so we also advise on tax-efficient dividend policies. For S corporations, we prepare Form 1120-S and issue Schedule K-1s to shareholders. S-Corp income (or losses) passes through to personal returns, avoiding double taxation. LLCs receive customized treatment: by default a single-member LLC’s income is reported on a Schedule C of the owner’s Form 1040, and multi-member LLCs file Form 1065 (partnership return) with K-1s. LLCs are typically pass-through entities, meaning the LLC itself pays no federal income tax; instead its profits flow through to members’ personal tax returns.

    Our corporate tax service includes:

  • C-Corp tax returns
  • S-Corp tax returns
  • LLC/Partnership returns
  • Consolidated and multistate returns
  • Audit-ready documentation

    ARNA’s expertise in all U.S. entity types means your corporate filings are accurate, maximally beneficial (we look for all available credits and deductions), and in full compliance with IRS rules and state laws.

Bookkeeping Integration with Tax Services

Accurate bookkeeping is essential for smooth tax preparation. ARNA integrates bookkeeping with our tax services to provide a complete financial management solution. We maintain your ledgers, reconcile accounts, and track income/expenses throughout the year so that your tax data is always up to date. Bundling bookkeeping and tax yields cohesive support that minimizes errors and maximizes savings. With one team handling your books and tax, we gain full visibility into your finances, allowing us to spot opportunities for deductions and avoid surprises.

    Our integrated services include:

  • Monthly bookkeeping
  • Real-time reporting
  • Tax-ready records
  • Year-end closing

    By combining bookkeeping with tax, ARNA offers better efficiency and deeper financial insight. This streamlined approach saves you time and money and makes tax season far less stressful.
