"The tax world can be a scary place for small business owners, especially sole proprietors that are running the show alone most of the time. With the ever-changing tax code, owners struggle to keep up with the do’s and don’ts of income tax, and it’s so important to stay up to date (or hire a CPA) to get it done right."
— Emily Dear, Co-Founder, regroupTAX
Taxes. They’re only one letter away from being a four-letter word. Frankly, it’s close enough in most people’s books.
According to studies, 60% of small business owners feel that administrative burdens, like mundane paperwork and attempting to understand seemingly undecipherable tax laws, are the most unpleasant part of tax season. It’s also a task that consumes an average of 80 hours (3 ⅓ days) each year.
Further complicating things 40% of small businesses fail to provide their tax providers (accountants, bookkeepers and tax professionals) with the proper records and documentation. Perhaps this is why almost 50% of small businesses end up filing extensions.
Your Guide to Small Business Taxes as a Sole Proprietor
While we can’t change the laws or that fact that have to file taxes, we can create this guide to help walk you through what you need to prepare and better understand the process.
Before we start, we want to emphasize that this guide is intended for small businesses operating as sole proprietorships (sole proprietors) who will file their business taxes along with their personal taxes using a Schedule C Profit or Loss From Business and Form 1040 Individual Income Tax Return.
Also, if you take any part of this guide to heart, remember this one point: It is to your advantage to work with a tax professional. Having an accountant, bookkeeper and, if necessary, a tax attorney, on your side can make a world of difference to your during tax season and throughout the year. (Yes, startups, we’re talking to you too.)
"For most small business owners, taxes end up at the bottom of a very long list of things to worry about. Having a professional handle your taxes can take an important load off of your shoulders (and off your mind), allowing you to stay focused on growing your company.

Sole Proprietorship and Your Small Business Taxes
A sole proprietorship (sole proprietor) is the most common form of small business ownership. As implied by the word sole, it a single-owner business. In the eyes of the Internal Revenue Service (IRS) and similar organizations, it is also considered an unincorporated business. (In other words, you’re not being publicly traded on the Nasdaq stock exchange.)
As a sole proprietorship is not considered a separate entity from the owner, business taxes are filed along with the owner’s personal taxes. You must file business taxes when your net earnings reach $400 or more.
While that sounds pretty straightforward, sole proprietorships often face higher scrutiny with over 2% of sole proprietor returns with receipts of $25,000 were audited — more than double the .8% audit rate for individual tax returns.
Should you have questions about your business structure and what’s best for you, it’s best to consult with a small business lawyer, accountant or both as the choice you make has legal and financial implications.
If you are a sole proprietor with less than $5,000 in business expenses, you may qualify to file a Schedule C-EZ. The requirements are very specific and if you’re unsure, it’s best to contact a tax professional.
Sole proprietors with of more than one business must fill out a Schedule C for each business.
The Goals to Aim For Every Tax Season
In addition to getting your taxes finished on time, your goals should be:
- Getting the reports, receipts and documents you need together ahead of time.
- Avoiding mistakes like missing or incorrect information that can lead to processing delays or even audits.
- Lowering your tax bill by maximizing your small business tax deductions.
"As tempting as it is to ignore, it’s worth catching up on overdue bookkeeping well before tax season rolls around. Having tax-ready books can help you comply with IRS recordkeeping requirements and file an effective tax return."
— Bryce Warnes, Content Coordinator, Bench
The Filing Deadline for Your Schedule C as a Sole Proprietor
The deadline for filing your Schedule C with Form 1040 is April 15. In 2017, April 15 falls on a Saturday and the first business day, Monday, April 17 is Easter Monday (It’s also Emancipation Day in the District of Columbia). As a result, in 2017, the filing deadline is April 18.
In most years, the deadline is April 15. If April 15, falls on a weekend, your return is due the next business day. If the next business day happens to be a holiday, you have one more day.
- If you owe business taxes, the deadline for paying these taxes is the 15th day of the 3rd month after the close of the fiscal year — March 15, June 15, September 15 and December 15.
- If, for any reason, you need to file an extension for your small business taxes, using Form 4868 submitted on or before April 18 deadline for personal income taxes. With an extension, you will have until October 17, 2017, to file your business taxes.
- As with any IRS payment deadline, if the date falls on a holiday or weekend, payment is due the next business day.

Understanding Your Schedule C
Even if you’re working with a tax professional (as we strongly suggest), it’s valuable to know what a Schedule C is and how it’s completed. The IRS has a detailed guide, but our hope is that you’ll find our walkthrough is a bit more friendly.
Line 1 — Proprietor and business Information
- Like most other tax forms, the top part of your Schedule C identifies you and your business.
- Name of proprietor — That’s you. Provide your full name, first and last.
- Social security number (SSN) — Enter your nine-digit social security number.
- It’s best if the name you provide matches the name you have on your social security card. If your name has changed for any reason, include documentation with your return and notify the Social Security Administration (SSA) to update your information.
Lines A and B — Principal business or profession, including product or service and principal business or professional activity code
- This is the business or professional activity that was the main source of income. If you own more than one sole proprietorship, you will need to complete a separate form for each business.
- If you’re in wholesale, retail or production services, you should also give the type of customer or client, for example: “Wholesale sale of hardware to retailers.”
- The complete list of codes is found at the end of the instruction guide.
Line C — Business name
- If you do business under your own name and don’t have a formal business name, you may leave this blank.
- If you have a formal business name and you also have an employer identification number (EIN), make sure that the business name you provide is the same as the one on your EIN.
Line D — Employer identification number (EIN)
- Also known as a federal employer identification number (FEIN), the main reason a sole proprietor would have one is to register with tax authorities to pay employees.
- If you do not have an employer identification number, you may leave this blank.
Line E — Business address
- If you have an employer identification number, the address you list should match the one you provided in your registration information.
Line F — Accounting method
- This is where you indicate which accounting method you’re using.
- A cash method is when you claim your income the moment it’s received — subsequently paying taxes on that income the following calendar year.
- An accrual method is when you claim income before it’s received in your bank account. An example would be claiming the amounts on an invoice before payment is received. With this system, you there’s a likelihood that you’ll pay taxes on income you haven’t received.
- Each method has its pros and cons, the deciding factor is what’s best for your business.
- If you’re unsure which method you’re using, your accountant and/or bookkeeper can give you the answers.
- The IRS also accepts “other” valid accounting methods. For the sake of brevity, we only went into the two most common methods.
- Once you choose an accounting method, it’s best to stick with it. The IRS prefers this as well.
- Certain businesses are also required to use specific methods, so again, check with a tax professional.
- A detailed overview is also provided in IRS Publication 538.
Line G — Material participation in the business
- Material participation means being actively involved in a substantive way in the business. For example, there’s a difference if you’re you a full-time employee of this company versus an investor. It is also a defining factor in claiming deductions. Key determinants include:
- Working more than 500 hours at or for the company during the year.
- You participated in the activity for more than 100 hours (with no other person participating more than you, the taxpayer).
- You participated in this activity for at least 5 consecutive years of the past 10 years.
- If you own rental property, like a condo or apartment, it is generally considered passive income that is taxed differently. This is when your accountant becomes very handy.
Line H — If you started the business in the current tax year
- Yeah for a simple one. If you did, check the box.
Lines I & J — Did you make any payments that would require you to file Form 1099 and if you did, did you file your 1099s?
- Form 1099-MISC, Miscellaneous Income is most often used by small businesses to report income paid to independent contractors.
- If you paid a contractor $600 or more in the previous tax year, you will need to complete a 1099.
- 1099s (with nonemployee compensation payments in box 7) must also be submitted to the IRS by January 31 each year.
- A best practice is to request that your contractors complete a W9 prior to working for you.
- 1099s are a primary tool for the IRS to track unreported income, so err on the side of caution in getting these completed and filed on time.
- As your 1099s are due before your income taxes, you should have already filed them and have them on hand.
Part 1 — Income
- This is the section where your calculate your gross profit and income (before deductions).
- Line 1 — Gross receipts or sales. (See instructions and check the box if this income was reported to you on Form W-2 and the “Statutory employee” box was checked.)
- In accounting terms, receipts are any money you take in while sales are literally from sales of a product. In human speak, this is the amount of money you earned this year.
- Statutory employees are classified as full-time life insurance agents, certain agent or commission drivers and traveling salespersons, and certain homeworkers.
- If you had both self-employment income and statutory employee income, you must file two Schedules C.
- Line 2 — Returns and allowances
- A return is exactly what you think it is — an item or product that was returned.
- An allowance is a discount is a reduction in the selling price in place of a refund.
- These are amounts given by you to your customers or incurred by you through returns.
- The amount you enter must be reported as a positive number.
- Line 3 — Line 1 minus Line 2
- Line 4 — Cost of goods sold (from line 42)
- Line 5 — Gross profit (Line 3 minus Line 4)
- Line 6 — Other income
- Other income can include interest from checking and savings accounts, debts that were written off but have now been claimed, prizes/awards and federal or state gasoline taxes/refunds.
- Line 7 — Gross income (Line 5 plus Line 6)
- Line 1 — Gross receipts or sales. (See instructions and check the box if this income was reported to you on Form W-2 and the “Statutory employee” box was checked.)
Part II — Expenses
- Often called the heart of the Schedule C, this is where you can claim your standard business tax deductions.
- With the claimed amounts, you must also have the proper documentation, such as invoices, receipts, utility bills, etc.
- Home office expenses (itemized and simplified method) are calculated in Line 30 of this section.
- The cost of goods sold (COGS or inventory) is calculated in Part III.
- Car and truck expenses are calculated in Part IV.
- Other expenses not covered in Parts II - IV can be listed in Part V.
- (All are covered in more detail below.)
Part II — Line 30 — Expenses for the business use of your home
- This is where you can claim your home office deduction. While there’s a common myth that claiming this deduction will increase your odds of being audited, most experts wholeheartedly debunk this urban myth emphasizing that there’s no statistical evidence to prove this case.
- The requirements that determine if you qualify for a home office deduction:
- A part of your home has to be set aside for business.
- This area has to be used exclusively for business.
- You work regularly from this area — 4 to 5 days a week, no less than 45 minutes at a time.
- There are two ways that you can calculate your home office deduction:
- The simplified method — With this method, you calculate the square footage of the space that you use as your home office then multiply this amount by $5.
- The maximum allowable deduction is $1,500 (300 sq ft x $5).
- Actual expenses (the complicated method) — Is best used when your expenses are greater than the $1,500 limit for the simplified method.
- In this method, you calculate a percentage of all the expenses related to your home office, including utilities, mortgage or rent payments, insurance, maintenance and repairs, etc.
- The factor that complicates things is whether you claim these items as a direct or indirect expense.
- Direct expenses, like the cost of a repair to your home office, can be claimed in full.
- Indirect expenses, like utility bills and mortgage/rent payments, may only be claimed as a percentage of the total cost.
- All the nitty gritty details of the home office deduction are outlined in IRS Publication 587. (A tax professional can also be your best friend on this one.)
Part III — Cost of goods sold (COGS)
- If your business is involved in producing or purchasing items for sale and your sales total more than $1 million, then you need to complete this section to account for the value of these items. (If your sales are less than $1 million, you may not have to complete this section. Let your tax professional be the ultimate judge of that one.)
- What makes calculating the cost of goods sold a bit different than inventory is that accounts for all the elements that go into creating this inventory, such as labor, materials and supplies.
- As the cost of goods sold can represent one of your largest expenses, ensuring this calculation is accurate is essential in lowering your taxable income.
- Valuation methods:
- You may value your inventory at cost, lower cost of market or any other generally accepted practice.
- If you use the cash method of accounting then you must use the cost method, which is simply the sum of your starting inventory and purchases minus your ending inventory.
- Lower cost of market (LCM) is when a business chooses to record the inventory cost that is lowest, either starting or current market price. This is most often used when a business has held inventory for a long time, when the inventory has become out-of-date or if market prices have dropped.
- If you use other methods, like first in, first out (FIFO) or last in, first out (LIFO), all you need to do is check other and attach an explanation.
Part IV — Information on your vehicle (car and truck expenses)
- You must complete this section if you have claimed car and truck expenses in Part II — Line 9 and are not amortizing or depreciating the cost or value of a vehicle using Form 4562.
- There are two methods for calculating car and truck expenses. (Because why have one when you can have two?)
- Actual expenses method — With this method you claim a percentage of costs, based on the amount you use your vehicle for business, based on every expense you incur to operate your car or truck, including fuel, maintenance, insurance and depreciation.
- Standard mileage method — In this simplified method, you multiply the amount of mileage associated with business by a standard mileage rate provided by the IRS. (Note: As the rates have changed every year since 2014, ensure that you are using the right rate.)
Part V — Other expenses
- Other expenses is a catch-all category for things that don’t fit or weren’t included under the general expenses in part II or in your home office, vehicle or costs of goods sold expenses.
- Notable items include:
- For more details, see IRS Publication 535.
Don’t Let Things Get Ugly
“Tax season has a reputation for being overwhelming, which can easily lead to mistakes along the way. But if you lean on the professionals, you can guarantee an error-free process that will minimize stress and maximize your tax savings.”
— Brendon Pack, VP, 1-800Accountant
While tax season conjures up a certain existential dread, it doesn’t have to spell disaster. Be your own best friend and keep yourself out of the way of that bus.
- Be prepared — Get all the things you need together. Be organized, systematic and even a little relentless.
- Get help — Working with a professional can help you maximize your refund, prevent mistakes and let you sleep better knowing that you’ve covered all your bases. When it comes to your taxes, these are the people you want to get to know:
- Bookkeeper — A small business owner’s best friend, this is your man or woman on the ground who can make your accounting software sing. Your bookkeeper can help you get everything ready for your accountant.
- Certified Public Accountant (CPA) — Your accountant is the one who gives everything that final eagle eye before filing your return on your behalf. (Note CPA is a specific professional designation.)
- Enrolled Agent (EA) — This an individual who has been licensed by the IRS or has at least five (5) years of experience working with the IRS. If you can’t afford an accountant, an EA is a cost-effective alternative.
- A tax lawyer — This is a big gun that you’ll only need to pull out if you’ve got a serious tax problem, such as the IRS inviting you to join them in court.
- File on time — While nearly 50% of small businesses end up filing extensions, you don’t have to be one of them.
- If the worst happens, file an extension using Form 4868 submitted on or before April 18 deadline for personal taxes. With an extension, you’ll have until October 17, 2017, to file your Schedule C. (If you know early on that you’ll need an extension, let the IRS know as soon as possible.)
- Even with an extension, any amounts you owe are still due on the original dates.
- There are two kinds of penalties for being late:
- Failure-to-file — 5% of the unpaid taxes for each month you’re late up to 25% of the total. (For micro-businesses, the penalty if you file more than 60 days late is either $135 or 100% of what is owed if the amount is less than the fine.)
- Failure-to-pay — .5% of the unpaid taxes for each month you’re late up to 25% of the total. (In other words, the penalty for not filing at all is 10x that of paying late.)
- If you pay at least 90% of what you owe and file your extension request by the April deadline, then you will not get a failure-to-pay penalty.
Become Your Bookkeeper’s and Your Business’ Best Friend
"Regardless of whether you hire someone to do your small business bookkeeping or not, you need to have a good bookkeeping system in place, understand how it works, and track some of your day to day business activities."
— Crystalynn Shelton, Writer, Fit Small Business
While the bulk of this guide deals with what needs to happen at tax season, best practices exist so that everything gets taken care of the right way throughout the year. Putting best practices like the ones below in place can also mean that you’re prepared for tax season well before the deadlines and the panic hits:
- Work with a bookkeeper and accountant all year long. Together you can make sure that you’re watching the things you ought and doing the things you should.
- With the rising number of cloud-based or virtual bookkeeping and accounting firms, you get added versatility and cost-effectiveness along with the needed expertise.
- Review the deductions you claimed this year and use them as a guide for setting up expense categories to track costs and receipts throughout the year. Then at tax time, all you have to do is check the balance sheet.
- Create a separate business bank account aside exclusively for taxes. Put money for taxes in this account as soon as you receive it to help keep you from falling behind on any estimated payments or tax deposits.
- Take advantage of the amazing array of small business software and financial tools, including:
- Accounting software, like Flare, FreshBooks, Less Accounting, SlickPie, QuickBooks Online, Xero and ZipBooks.
- Document scanning and storage from Hubdoc, Ledger Docs and Neat.
- Time tracking and scheduling tools like TSheets, When I Work and Jobber.
- Receipt scanning apps like Expensify, Receipt Bank and Shoeboxed.
- Mileage tracking apps like MileIQ, TripLog and TrackMyDrive.
- Easy invoicing and accounts payable from Plooto and Invoicera.
- Small business payroll software like Wagepoint.
- Back up your financial data regularly — create two digital copies (in two different locations) and one additional offline copy.
- Keep good records — Follow all the tips above and keep past tax records for a minimum of three years or as long as seven, depending on the claims you’ve made.
The Healthcare Debate and Your Taxes
Unless you're under a self-enforced news ban, it's kind of hard to miss all the stories on the new administration's dislike of the Affordable Care Act (ACA). As a result of an executive order issued in January, the IRS has decided NOT to enforce the proof of coverage requirement. However, if you're an employer, the American Payroll Association and the IRS advise that the ACA coverage and reporting regulations for employers are still in place.
