How to file Small Business Taxes, Types, and Deductions

Owning a small business is rewarding, but it comes with responsibilities, including taxes. Small businesses typically face various types of taxes, such as income tax, self-employment tax, payroll tax, and sales tax. Your specific tax requirements will depend on factors like your business structure whether it’s a sole proprietorship, LLC, or S corporation the state you operate in, and whether you employ staff. Familiarizing yourself with these taxes can save you from costly penalties and help keep your business financially healthy.

Types of Small Businesses Taxes

Income Tax

Nearly all businesses must file an annual income tax return, but the rate and form depend on your business structure. Sole proprietorships, partnerships, and S corporations pass their income directly to the owner’s personal tax return, meaning profits are taxed at the individual level. In contrast, C corporations face double taxation, where income is taxed both at the corporate level and again when distributed as dividends to shareholders. Choosing the best structure for your business can help reduce income taxes and align with long-term goals.

Form 1040 Schedule C (Sole Proprietorships) Used by sole proprietors to report income and expenses.

Form 1065 (Partnerships) File by Partnerships to report income, deductions, and other tax information.

Form 1120 Used by C corporations to file separate corporate tax returns; the corporation pays taxes directly.

Form W-2 Issued to employees to report wages, withheld taxes, and other employment income details.

Form 1099-NEC Issued to contractors for reporting non-employee compensation.

Self-Employment Tax

For sole proprietors and partners, self-employment tax covers Social Security and Medicare, calculated at 15.3% of net earnings. Half of this tax is deductible, which helps reduce taxable income. Keeping precise records of income and expenses ensures an accurate self-employment tax calculation, and many small business owners find that working with a CPA or tax software helps them manage this responsibility effectively.

Payroll Tax

Businesses with employees must withhold federal and state taxes from their wages and cover additional employment taxes. This includes Social Security and Medicare contributions, which the employer matches. Payroll taxes require careful management, as errors can lead to penalties. Many business owners use accounting software to handle payroll taxes efficiently, ensuring they stay compliant with IRS regulations.

Excise Tax

Excise tax applies to specific products like fuel, tobacco, and alcohol, often paid by the manufacturer or retailer rather than the consumer. Small business owners selling these goods must ensure they comply with both state and federal excise tax requirements to avoid penalties. Many businesses include excise tax costs in their pricing to cover this expense, and working with a tax professional can help manage accurate tax payments.

Estimated Taxes

Employment tax covers Social Security, Medicare, and income tax withholding for employees. Employers must match contributions for Social Security and Medicare, which adds to payroll costs. Many small businesses use payroll software or services to handle employment tax, ensuring compliance and accurate records. Staying updated on tax rates helps business owners avoid errors and penalties.

Sales Tax

In most states, businesses must collect sales tax on goods and some services, then remit it to the state. Sales tax rates vary depending on location, with some municipalities adding additional rates on top of the state rate. Regularly setting aside the collected tax ensures you have funds ready when it’s time to remit, helping avoid last-minute shortages and penalties.

State and Local taxes for Small businesses

Property Tax: If your business owns real property or equipment, you may need to pay property tax. Local governments assess property values and apply tax rates that may vary each year. Property tax can significantly impact your budget, so planning for it in advance can help maintain cash flow, especially if rates increase.

Income tax: Nearly all businesses must file an annual income tax return, but the rate and form depend on your business structure. Sole proprietorships, partnerships, and S corporations pass their income directly to the owner’s personal tax return, meaning profits are taxed at the individual level. In contrast, C corporations face double taxation, where income is taxed both at the corporate level and again when distributed as dividends to shareholders. Choosing the best structure for your business can help reduce income taxes and align with long-term goals.

Tax Deductions For small businesses

Home Office Deduction

If part of your home is exclusively used for business, you may qualify for the home office deduction. This deduction can reduce your taxable income significantly by covering a portion of rent, utilities, and maintenance costs based on the size of your workspace. Keeping detailed records of these expenses ensures an accurate deduction claim.

Vehicle Expenses

Using a vehicle for business offers two ways to claim deductions: mileage or actual expenses. The mileage deduction allows a simpler option, while actual expenses (fuel, maintenance, and depreciation) may be beneficial for high-use vehicles. Choosing the right deduction method can maximize savings, so keeping mileage logs or detailed receipts is essential.

Equipment and Supplies

Office equipment, computers, and supplies can often be deducted immediately, helping you recover costs quickly. The IRS allows many of these purchases to be deducted under Section 179, reducing your taxable income for the year they’re purchased. Maintaining clear records and receipts makes it easier to support these deductions if needed.

Utilities and Rent

For businesses with dedicated office space, rent payments and necessary utilities like electricity and internet are deductible. These expenses can add up quickly, so deducting them helps reduce your overall tax burden. Clear documentation of rent and utility payments ensures that you’re prepared to back up these deductions if audited.

Travel and Meals

Business travel and a portion of meal expenses can be deducted, including transportation, lodging, and meals related to conferences, meetings, or client visits. Documenting the business purpose for each trip is essential, as these deductions are often closely scrutinized by the IRS. Proper documentation helps you claim the full deduction and minimizes risks in case of an audit.

Important forms for small business taxes 

Form 1040 Schedule C

Sole proprietors report their income and expenses on Form 1040 Schedule C, which integrates with their personal tax return. This form includes categories for common business expenses, simplifying deduction claims and providing a clear view of net profit. Filing Schedule C accurately is key to avoiding penalties and managing personal and business tax responsibilities.

Form 1065

Partnerships file Form 1065 to report income and deductions, and each partner receives a Schedule K-1 outlining their share of the earnings. This form ensures that each partner reports their portion on their individual tax returns, keeping everything in compliance. Filing Form 1065 on time is crucial for partnerships to avoid penalties and keep tax information organized.

Form 1120 or 1120-S

Corporations file separate tax returns on Form 1120 (C corporations) or 1120-S (S corporations). While C corporations pay taxes at the corporate level, S corporations pass income through to shareholders, who report it individually. Understanding these forms and the tax implications of each structure can help you make informed choices for your business.

Form W-2 and 1099-NEC

For employees and contractors, Form W-2 and Form 1099-NEC are essential for reporting income. Employers are responsible for issuing these forms on time to ensure accurate reporting and compliance with tax regulations. Proper management of these forms helps prevent issues with employees or contractors and ensures you’re meeting IRS requirements.

Filing Deadlines And Estimated Taxes

Quarterly Estimated Payments

Most business owners need to make quarterly estimated tax payments to cover income tax and, for self-employed individuals, self-employment tax. These payments are due on April 15, June 15, September 15, and January 15. Planning ahead and setting reminders helps avoid penalties and ensures you’re covered when taxes are due.

Annual Filing Deadline

For most small businesses, the annual filing deadline is April 15, though corporations may have different dates. Missing the filing deadline can result in penalties, so preparing early and using accounting software can streamline the process. A CPA can also help ensure you meet deadlines and accurately file your returns.

Extensions

If you need extra time to file, you can request a six-month extension with Form 4868 for personal returns or Form 7004 for business returns. Remember, an extension only moves the filing date not the payment date so any owed taxes must still be paid by the original deadline to avoid interest.

Minimize your tax Liability

Take Advantage of Retirement Contributions

Retirement plans like SEP IRAs or solo 401(k)s allow business owners to reduce taxable income while building future savings. These contributions are tax-deductible, and small business retirement plans offer higher contribution limits than standard IRAs. Consulting with a tax advisor can help you make the most of these options.

Defer Income and Accelerate Expenses

Deferring income or prepaying expenses can help manage taxable income, especially if you expect fluctuations in revenue. Delaying income recognition or accelerating deductions enables you to balance high-income years, which can reduce your tax burden significantly. This strategy works well for businesses experiencing seasonal changes in income.

Claim Tax Credits

Tax credits directly reduce your tax liability and can make a significant impact. For instance, the Small Business Health Care Tax Credit is available to businesses that provide employee health insurance, and the Work Opportunity Tax Credit offers incentives for hiring from specific groups. Familiarizing yourself with available credits can yield substantial savings.

Track Carryovers

Some deductions and credits might not apply fully in a single year, allowing them to carry over to future years. By tracking these carryovers, you can maximize tax benefits, especially during lower-income years. A tax professional can help ensure that carryovers are correctly applied, maximizing your tax efficiency.

FAQs

1. What qualifies as a business expense for tax purposes? 

Business expenses are costs that are "ordinary and necessary" for running your business, according to the IRS. Common deductible expenses include office supplies, utilities, rent, travel costs, and equipment. To qualify, expenses should directly relate to your business and be documented properly.

2. Do I need to pay taxes on my small business quarterly? 

Yes, most small business owners, especially sole proprietors, partners, and self-employed individuals, need to make estimated quarterly tax payments to cover both income and self-employment taxes. These payments help avoid large lump sums at year-end and prevent penalties.

3. Can I deduct my home office for tax purposes? 

If you use a part of your home exclusively and regularly for business, you may qualify for a home office deduction. The deduction can be calculated using the simplified method (a set rate per square foot) or the regular method (calculating actual expenses based on percentage of home use).

4. How much should a small business save for taxes? 

A good rule of thumb is to set aside 25-30% of your business income for taxes, though the actual amount may vary based on income, expenses, and business structure. Consulting with a tax professional can help determine a more accurate percentage for your specific situation.

5. What happens if I miss a tax deadline for my business? 

Missing a tax deadline can result in penalties and interest charges from the IRS. If you realize you’ll miss a deadline, consider filing for an extension (though this only extends filing, not payment). Paying as much as you can by the deadline and contacting a CPA can help minimize potential fees.
