Our Guided New Business Formation & LLC Setup Services

  • Business Entity Selection

    Your structure shapes taxes, liability, and growth. We evaluate whether an LLC, corporation, or another entity best serves your goals, weighing pass through treatment, protection, and flexibility, so you launch with a structure that fits your plans rather than one you regret and unwind later.

  • LLC Formation and Filing

    Forming an LLC involves precise, state specific steps. We handle the formation paperwork and filings correctly, establishing your LLC properly from the start, so your business is recognized, your liability protection stands, and you avoid the errors that rushed setups so often create.

  • EIN Registration

    Most new businesses need a federal tax ID. We obtain your EIN, the number that lets you hire employees, open bank accounts, and file taxes, so this essential step is handled correctly and your business is ready to operate officially without frustrating delays or complications.

  • Corporate Formation Services

    Incorporating carries specific requirements and lasting implications. We guide the formation of your corporation, handling the filings and establishing the structure properly, so whether you choose an S or C election, your business begins on firm legal ground and aligned with your tax strategy.

  • Business Structure Tax Planning

    How you form your business determines what you owe. We plan your structure with taxes in mind, considering elections, self employment exposure, and future growth, so your entity works to minimize liability from day one rather than costing you through an inefficient setup.

  • Startup Compliance Guidance

    New businesses face obligations they never expected. We walk you through the compliance requirements that come with launching, from registrations to recordkeeping, so you understand your responsibilities and start off in good standing rather than discovering missed steps once problems have already begun to surface.

Tax Efficiency From Day One

Early choices shape your future bills. We plan your formation with taxation in mind, positioning your entity and elections to minimize liability, so your business starts saving from the outset rather than paying more simply because no one considered the tax angle at launch.

Frequently Asked Questions

  • Should I form an LLC or a corporation?

    It depends on your goals for taxes, liability, and growth. LLCs offer flexibility and pass through taxation, while corporations suit different plans. We carefully evaluate your situation and recommend the structure that fits best, then handle formation so you launch correctly and confidently.

  • How long does it take to form an LLC?

    Formation time varies by state and filing method, ranging from a few business days to a few weeks, with more steps before you are fully operational. William Diker, CPA in New York, New York guides the process, so nothing stalls or gets overlooked.

  • Do I need a registered agent for my LLC?

    Yes. Every LLC needs a registered agent with a physical address in the formation state to receive legal and government correspondence. We carefully help you arrange this correctly, so your business stays properly served and compliant from the moment it is formed onward.

  • Do I need an EIN to start my business?

    Most businesses do. An EIN lets you hire employees, open bank accounts, and carefully file taxes, functioning like a Social Security number for your company. We obtain it for you as part of formation, so this essential step is handled correctly without delay.

  • What is the difference between a single member and multi member LLC?

    A single member LLC has one owner and is taxed like a sole proprietorship by default, while a multi member LLC has several owners and is taxed like a partnership. We carefully help you structure and file correctly for whichever describes your business.

  • Do I need an operating agreement for my LLC?

    Strongly recommended, and required in some states. An operating agreement defines ownership, profit sharing, and roles, helping prevent disputes and carefully protect your liability shield. We reliably help ensure yours is in place, so your LLC rests on a clear, solid internal foundation.

  • Does an LLC protect my personal assets?

    Generally, yes. A properly formed and maintained LLC separates your personal assets from business debts and legal claims, though that protection is not absolute. Drawing on 45+ years serving New York, New York, William Diker, CPA helps you form and maintain it correctly.

  • Can my LLC choose how it is taxed?

    Absolutely. An LLC can keep its default treatment or elect to be taxed as an S corporation or C corporation when advantageous. We evaluate which option lowers your overall liability, then file the election properly and on time, so the choice truly holds.
