Small business tax preparation checklist 2024: 6 steps business owners should know

Image Alt Text

As a small business owner, you’ve got plenty on your plate. From hiring the right employees to overseeing the daily operations of your company, it can be challenging to find the time to manage your books.

However, staying prepared year-round can help make filing easier when tax season comes around. We’ve compiled the essential steps you need to follow to streamline your small business tax prep and filing process.

This small business tax preparation checklist breaks down the six basics of filing small business taxes and includes a downloadable checklist to stay on top of your small business tax prep needs—including what tax forms to file and documentation to gather.

1. Know the types of small business taxes

5 types of business taxes: income tax, estimated taxes, excise tax, self-employment taxes, and employment taxes

All businesses have to pay certain taxes to the IRS and state tax authorities. As a small business owner, it’s your responsibility to ensure that you meet your federal and state tax obligations. Whether you run a sole proprietorship , partnership , S corporation, or C corporation, these are the five main types of taxes your business may be responsible for.

Income taxes

Income taxes are based on the money your business makes and are paid on both a federal and state level. The amount you owe depends on how your business is set up.

C Corporations deal with double taxation, meaning they pay taxes twice—first on the money the business makes and then again when they pay dividends to their owners (shareholders). The current federal tax rate for C corporations is 21%.

Unlike C Corporations, businesses like sole proprietorships, partnerships, and S corporations pay income taxes individually. These entities are known as “flow-through” entities (also known as pass-through entities ) because the income is first reported at the entity level and then “flows-through” to the individual’s tax return on Schedule K-1.

Also unlike C Corporations, no federal taxes are paid at the business level for these types. The amount of income tax you pay depends on your personal tax bracket.

A business’ state income tax varies by state—and sometimes by city. Depending on where you do business and make money, you may have filing requirements in different jurisdictions. The rules and requirements are complex, and it’s best to consult your tax advisor if those rules apply to you.

Estimated taxes

Businesses are required to pay estimated taxes quarterly. If you run a C Corporation and you think you'll owe more than $500 in taxes, you have to pay estimated taxes every quarter. For all other business structures, you need to pay estimated taxes, too, but only if you expect to owe more than $500 on your personal tax return.

The estimated tax deadlines for 2024 are as follows:

If the date for paying taxes falls on a holiday or weekend, taxes will be due the following business day.

Self-employment taxes

If you're a sole proprietor or a partner actively involved in your business, you need to pay both the employee and employer parts of Social Security and Medicare taxes. The current self-employment tax rate in 2024 is 15.3% and is divided as follows:

If you earn more than $400 from your business, you have to report it as self-employed income and pay the self-employment tax .

Employment taxes

When you have employees in your small business, there are certain taxes you need to handle, known as employment or payroll taxes. Here's what's included:

Consult a tax advisor if you’re unclear about any employment taxes you may be responsible for.

Excise tax

Excise taxes are additional taxes you may have to pay on specific goods or services. If your business performs any of the following, you may have to pay excise taxes:

For a full list of which goods and services excise taxes may apply, refer to the excise tax overview page on the IRS website.

2. Know what business tax forms you need to file

There isn’t a one-size-fits-all business tax form . Depending on your business structure, you’ll need specific forms—like Form 1099-MISC or Form 1120—to report profits, losses, deductions, and credits to the IRS. Here are some common IRS forms for reporting small business taxes:

If you have questions about which forms to file or how to fill them out, a dedicated tax professional can help ensure you file correctly and on time.

3. Create a tax filing calendar

Twelve illustrated calendar icons accompany a list of important 2024 tax deadlines for small business owners.

As a small business owner, it's easy for tax deadlines to slip your mind. However, it’s important to keep track of when tax payments are due and when you need to file taxes. Unfortunately, the IRS doesn’t take tardiness or failure to pay lightly. To keep your business cash flow in good shape, consider creating a tax calendar.

Here are the essential small business tax dates for 2024:

If any of these dates fall on a weekend or holiday, returns and payments are due the following business day.

5. Make note of common tax deductions and credits

Tax deductions and credits are excellent opportunities to reduce your small business tax bill. This is because certain expenses—such as health insurance and office expenses—and investments may be deductible from your taxable income, reducing how much you’ll owe after you file your return.

Knowing which tax breaks and credits may apply to your business is an important step in preparing your business taxes.

Small business tax deductions

Some of the notable small business tax deductions you may qualify for include:

Small business tax credits

There are many different small business tax credits that you may qualify for. Here are some common business tax credits you should be aware of:

Visit the IRS’s Business Tax Credits page for more information on tax credits your small business may be eligible for.

6. Request a filing extension if needed

If your tax situation is complicated, or you can't gather all your documents by the regular tax deadline, consider requesting an extension. You can use Form 7004 to get a six-month extension for reporting your business income.

Remember, an extension to file doesn't mean you get more time to pay. You still need to keep up with your estimated tax payments during this period. Falling behind could result in a fine.

As with other taxpayers, the IRS is eager to collect tax payments, so they’re often willing to work with small business owners to find a solution. If paying on time is tough, contact the IRS early to discuss a payment plan. The sooner, the better.

Find peace of mind come tax time

Running a business can be stressful, but filing taxes doesn’t have to be. This small business tax preparation checklist can help save precious time you’d be spending navigating complex state tax, sales tax , and employment issues, so you can put that time back into your business.
