Consider Electing C-Corp Taxation / S-Corp Governance

Your LLC is subject to pass-through taxes by default. Most LLCs retain this tax classification. Some LLCs may be eligible for C-Corp or S-Corp tax treatment.

    • S-Corp helps owner-employees with more than $75,000 per annum save on self-employment tax.
    • C-Corps are subject to double taxation. The corporation pays taxes on profits, and members pay taxes for distributions. C-Corps may offer low tax rates for retained earnings if profits exceed $250,000 per owner.

Apply for Business Licenses & Permits

Licenses and permits are required to legally run your business. You can search for your type of business and the location you live in using the Small Business Administration Business License & Permit Look-up Tool. This will allow you to quickly navigate through the many federal, state, local, and international requirements.
