Do the words “tax season” make you shudder? You’re not alone. Over half of US adults say tax season stresses them out. And when you run your own business, your tax time heebie-jeebies are bound to be even more severe. 

Tax season is faster and easier when your bookkeeping is organized. And our partners at Bench will handle all of your small business bookkeeping, and even file your taxes for you.

But if you’re filing your own taxes, read on. We’ll cover all of the forms you will need to file and any tax deadlines you will need to meet—plus how to file on time or get an extension. 

The documents you need to file taxes

When you file your tax return, you must be able to prove what you earned and what you spent —for the sake of reporting income, as well as claiming tax deductions. These records are not submitted with your return, but you’ll use them to calculate your total income and expenses for the year. However, you will need to have them on hand in the unlikely event you’re audited.

Basic info for filing small business taxes

  • Personal and business info: Your address, the address of your business, your full name, and your Social Security Number (SSN).

  • Last year’s filing: Having your previous return on hand makes it easier to complete this year’s return and keep track of info like depreciable expenses.

  • A Tax ID number: There are a variety of different numbers you may use as a tax ID number—from your SSN to your Employer Identification Number (EIN). Not sure which method to use for your business? This article on tax ID numbers offers a handy rundown.

Records of small business revenue

  • Invoices you sent to clients: Keeping copies of any communications and paid invoices helps you track your revenue and can support your case if your revenue or income are ever questioned by the IRS.

  • Records of goods sold: Cash receipts, or transaction lists from an online store or point of sale, can serve as a record of revenue you’ve earned.

  • Other sales records tracking revenue: It’s smart to hold on to any records of revenue you’ve received throughout the year.  In lieu of organized bookkeeping and regular income statements, you can use them to calculate your revenue for the year.

Records of expenses

By subtracting your expenses from your revenue, you get your total income for the year. That’s essential for filing. Also, many expenses are deductible—and if you make deduction claims, you’ll need to back them up.

Be sure to keep accurate records of the following tax expenses

  • Rent receipts

  • Office supplies receipts

  • Employee salaries

  • Mileage records

  • Other deductible expense receipts

Annual financial statements

An income statement, balance sheet, and (if you use accrual accounting) cash flow statement for the year will make filing a return easy. Comprehensive financial statements give you all the info you need to file. If you haven’t made financial statements part of your business strategy, now may be the time to hire a bookkeeper.

Essential tax forms and deadlines

Once you have your documents in order, obtain the forms you’ll need to file your return. The exact forms you’ll use, and the deadlines for filing, depend on your business structure.

Tax forms and deadlines for sole proprietors

Filing Deadline: April 15, 2024 (the same as your personal taxes)

There’s no need to file a separate return for your business. Report your business income and expenses on Schedule C of your personal tax return. If you’re itemizing deductions, list them on Schedule A.

The IRS instructions will walk you through the process of tallying your expenses and revenue for the year, and determining your income. 

Tax forms and deadlines for LLCs

Filing Deadline: April 15, 2024 (single member)

Filing Deadline: March 15, 2024 (multi member)

If you’re a single member LLC, you’ll file your taxes the same way you would as a sole proprietor. 

If you’re a multi-member LLC, you will elect to file taxes as either a partnership or an S corporation.

Tax forms and deadlines for partnerships

The partnership files Form 1065, and each individual files a Schedule K-1 to report what they’ve made and lost during the year. Partners claim unreimbursed business expenses on Schedule E.

Partnership filings, and Form 1065, can get pretty complex. For this reason, we recommend working with a tax professional to file your taxes.

Tax forms and deadlines for C corporations

Filing Deadline: April 15, 2024

In addition to your personal tax return, you’ll file a separate return for your corporation using Form 1120. This form is similar to Schedule C of your personal tax return, but more complex—and separate from your personal finances. Most business owners hire an accountant to help with Form 1120. 

Tax forms and deadlines for S corporations

Filing Deadline: March 15, 2024

You’ll file a Form 1120S for your corporation, and each shareholder will need to report their profits and losses with Schedule K-1. Similarly to a C corporation return, most S corps get help from an accountant to file taxes

Tax forms and deadlines for businesses that hire contractors

Filing Deadline: Sent to recipients by January 31, 2024

If you’ve paid $600 or more to a contractor, you need to file Form 1099. One copy of this form goes to the IRS, for the sake of filing your own taxes; another copy goes to the contractor, so they can use it to file their taxes.  If you’ve hired more than one contractor you will need to file a separate Form 1099 for each contractor.

How to file taxes online

Gone are the days of filing paper returns. The most efficient (and popular) way to file taxes with the IRS is online. 

To file your taxes online, you have two options: Free File, or Free File Fillable Forms.

IRS Free File

The IRS has partnered with 8 providers who offer free versions of their accounting software that you can use to file your taxes online. You’re automatically enrolled in Free File once you sign up with one of these providers— there’s no need to sign up through the IRS website.

Most providers offer a basic software package for free. These typically aren’t able to cover all the needs of a business—such as filing itemized deductions. You’ll need a paid version for that; the packages recommended for sole proprietors range from $25 ( to $85 (H&R Block).

IRS Free File Fillable Forms

Essentially, Free File Fillable Forms lets you complete IRS forms online, through the IRS website. These forms will do basic calculations for you, but they don’t check for errors.

Fillable Forms will automatically calculate your tax refund, and you can elect to have your return transferred directly to your bank account. You can also resolve any taxes due online.

If your business is small and relatively simple—like a sole proprietor—and you’re already experienced with filing taxes for your business, Fillable Forms may be a good choice. 

Otherwise, the process may intimidate you, and you run the risk of making errors. In that case, you may be better off having someone file your taxes for you.

How to get an extension

If it looks like you’ll be late filing taxes, file for an extension ASAP.  An extension will save you from IRS late filing penalties, and requesting an extension is pretty straightforward.

Filing a tax extension for your sole proprietorship or single-member LLC

If you plan to pay your taxes online, you can get a six-month extension through the IRS payment portal.

Otherwise, you can request an extension by filing IRS Form 4868.

Filing a tax extension for your multi-member LLC, partnership, or corporation

You can file for a six-month extension using IRS Form 7004

File early, rest easy

If you can, file your taxes early—meaning, well before the deadline. This may take some prep, but it has advantages.

First, you’ll get your tax refund earlier. Remember, a tax refund is your money—you just happened to overpay it to the IRS, and they’re holding on to it. Your money isn’t collecting interest while the IRS holds it. The sooner you get it back, the sooner you can put it to work for your business.

Second, you’ll have the info you need to start planning your estimated taxes for the coming year—you can check one more item off your tax to-do list.

To file early, you’ll need tip top books. The more organized your books, the easier it is to get the numbers you need to file your return. The best way to stay organized is to do your bookkeeping throughout the year, rather than handling it all in one mad scramble come January.

If you think you’ve submitted your taxes twice, don’t worry. We got the perfect article for you: Filing Duplicate Tax Returns? Here’s What to Know and Do

In closing

Tax time doesn’t have to be stressful. And it won’t be, so long as you have everything you need to approach it in an organized way. Your filing date, and the forms you need, vary according to your business structure—so make sure you know what’s needed before the deadline comes.
