Deidre can help with:

Clergy

Clergy have dual tax status as both employees and self-employed individuals. Since a church does not withhold taxes, clergy are responsible for paying taxes as self-employed people.
Multi-state income

This usually happens when tax payers work across state lines or have lived in multiple states in a tax year.
ITIN

An individual tax identification number (ITIN) helps people file taxes without a Social Security number.
Small Business Advanced Certified

Proprietorships, C corps, and S corps all file yearly taxes, but the forms used to file depend on the way the business is set up.

Entity Formation Tax Savings: Potential savings based on estimated self-employment tax savings of sole proprietor (Schedule C) users with over $40,000 in profit in 2023 by taking an S Corp election and filing in 2024, net of salary payments and payroll taxes. Election must generally be made by the due date of the return for the year prior to the year the S Corp election is to take place. Savings requires payment of a reasonable salary. Other requirements apply, and additional fees like tax preparation and payroll services are not included. Overall tax savings will vary based on your circumstances. All tax situations are different. Taxes are only one consideration in determining whether to form a business. You may want to seek the advice of an attorney to evaluate all of the relevant considerations. Block Advisors Business Formation Products and Services provide automated online tools that you can use to help meet your business formation needs and are not tailored to your particular situation. See our FAQs for more information.
