Starting a business can be both exciting and challenging. One crucial aspect that new business owners must navigate is understanding their tax obligations. This guide provides an overview of essential tax considerations for new businesses, including how to comply with federal and state tax requirements, maximize deductions, and stay on top of important deadlines.

Federal Tax Obligations

Federal Income Tax

All businesses are subject to federal income tax. How income is reported and taxed depends on the structure of the business—such as a sole proprietorship, partnership, corporation, or limited liability company (LLC). For example, some entities report business income directly on the owner’s individual return, while others file separate business tax returns. LLCs in particular can be taxed in different ways depending on elections made with the IRS.

Maria started a sole proprietorship and learned that she needed to report her business income and expenses on her personal tax return using Schedule C. Understanding this filing requirement helped her prepare adequately for tax season.

Federal Payroll Taxes

If you have employees, you are responsible for withholding federal income tax, Social Security tax, and Medicare tax from employee wages. In addition, employers generally pay a matching share of Social Security and Medicare taxes. Employers must also follow federal deposit schedules and file required payroll tax returns, such as quarterly or annual employment tax forms, to report wages and taxes paid.

John hired his first employee and learned that he needed to withhold federal income tax, Social Security, and Medicare taxes from the employee’s paycheck. He also accounted for the employer’s matching share of Social Security and Medicare and set up a system to make required deposits and file payroll tax returns on time.

Federal Self-Employment Tax

Sole proprietors, partners, and many LLC members who are not treated as employees are generally subject to self-employment tax, which covers Social Security and Medicare contributions. This tax applies when net earnings from self-employment reach at least $400 for the year and is separate from federal income tax. Self-employment tax is calculated using Schedule SE and is often paid through estimated tax payments.

Lisa, an independent contractor, calculated her net earnings from self-employment and determined that they exceeded the applicable threshold. She used Schedule SE to calculate her self-employment tax and made quarterly estimated payments to cover both income tax and self-employment tax.

State Tax Obligations

Sales and Use Tax

Many states require businesses that sell taxable goods or services to register for and collect sales tax. Rates, filing frequencies, and rules vary widely by state and may depend on where the business has a physical or economic presence.

Tom opened a retail store and registered for a sales tax permit in his state. He collected sales tax on each sale and remitted it to the state according to the required filing schedule.

State Income Tax

Most states impose an income tax on businesses operating within their jurisdiction, though the rules, rates, and filing requirements differ by state and by business structure. Some businesses file separate state returns, while others report business income on the owner’s individual return.

Emily’s LLC operated in a state with a 5% income tax rate. She reviewed her state’s rules and filed the required state income tax return to remain compliant.

State Payroll Taxes

In addition to federal payroll taxes, businesses with employees must comply with state payroll tax requirements. These may include state income tax withholding and state unemployment insurance taxes, with registration, reporting, and payment rules set by each state.

When Joe expanded his business to include employees, he registered with his state tax agency and unemployment office and ensured that all required state payroll taxes were withheld, reported, and paid on time.

Maximizing Tax Deductions

Common Business Deductions

Businesses may deduct ordinary and necessary expenses incurred in carrying on a trade or business. Common examples include office supplies, advertising, travel, and professional services. Proper documentation and recordkeeping are important, and some costs may need to be capitalized and recovered over time rather than deducted immediately.

Sarah carefully tracked her business-related expenses and kept receipts and records throughout the year. This allowed her to accurately claim allowable deductions and support them if questions arose later.

Home Office Deduction

If you use part of your home for business, you may qualify for the home office deduction if the space is used both exclusively and regularly for business and serves as your principal place of business. The deduction can generally be calculated using either an actual-expense method, which allocates home expenses based on business use, or a simplified method based on square footage.

Alex converted a spare room into a dedicated home office that he used regularly and exclusively for his business. After reviewing the available calculation methods, he claimed a home office deduction using the approach that best fit his records.

Start-Up Costs

Certain start-up and organizational costs incurred before a business begins operating may be partially deductible in the first year. Generally, up to $5,000 of start-up costs may be deducted, with any remaining amount amortized over 15 years. This first-year deduction is reduced dollar-for-dollar when total start-up costs exceed $50,000 and is eliminated entirely at $55,000. The business must be actively operating to claim these deductions.

Rachel incurred significant costs while preparing to launch her consulting business. Once the business began operating, she deducted a portion of her start-up costs in the first year and amortized the remaining amount over the required period.

Staying On Top of Deadlines

Federal Tax Deadlines

  • Quarterly Estimated Taxes: Individuals generally must make estimated tax payments if they expect to owe at least $1,000 in tax when filing their return, while corporations generally have a lower threshold. Safe-harbor rules may help taxpayers avoid penalties if certain payment requirements are met.
  • Annual Tax Returns: Filing deadlines vary by business type. Sole proprietors typically report business income on their individual returns, partnerships and S corporations generally file earlier in the year, and C corporations usually file by the 15th day of the fourth month after the end of the tax year.

Nick reviewed his business structure and determined that he needed to make quarterly estimated tax payments. He also confirmed the correct filing deadline for his type of business and marked it on his calendar to avoid late filing.

State Tax Deadlines

State tax deadlines often align with federal deadlines, but this is not always the case. Filing and payment schedules can differ by state and by tax type, making it important to verify requirements with the appropriate state tax authority.

Jenna checked her state’s tax agency website and confirmed that her state’s estimated tax and filing deadlines closely matched the federal schedule, helping her coordinate her tax planning.

Final Thoughts

Starting a business involves understanding and managing a range of tax obligations. By staying informed about federal and state requirements, understanding available deductions and their limitations, and tracking important deadlines, business owners can improve compliance and reduce the risk of penalties. Many new businesses also choose to work with a tax professional to better understand how general rules apply to their situation.
