How to Deduct Start Up Costs on Schedule C

For sole proprietors and other self-employed individuals, Schedule C of Form 1040 is the standard for reporting business income and expenses. The costs incurred before your business officially opens its doors are subject to special tax treatment. The IRS divides these pre-opening expenditures into two categories—start-up costs and organizational costs—which are considered capital investments in your business’s future. Because of this classification, they cannot be fully deducted in the same way as regular, ongoing operational expenses.

Identifying and Distinguishing Pre-Opening Costs

To properly deduct expenses, you must distinguish between start-up costs, organizational costs, and regular business expenses. The key timing element is that both start-up and organizational costs are incurred before the day your active business begins.

Start-Up Costs

The Internal Revenue Service (IRS) defines start-up costs as expenses paid or incurred for investigating the creation or acquisition of an active trade or business, or for creating one. These are costs you would be able to deduct if they were paid to operate an existing, similar business. Common examples include:

• Market research
• Advertising for a grand opening
• Travel to meet with potential suppliers
• Wages for employees in training
• Fees for consultants or attorneys assisting in business planning

Organizational Costs

Organizational costs are expenses related to the legal formation of a corporation or partnership. Examples include state filing fees, legal services for drafting documents like a partnership agreement, and fees for accounting services related to setting up the business structure. While corporations and partnerships often have both cost types, sole proprietors typically only incur start-up costs, as they do not have formal legal structure requirements.

Certain expenses are explicitly excluded from both categories. You cannot include deductible interest, taxes, or research and experimental costs. The costs of acquiring depreciable business assets, such as buildings or equipment, also do not qualify and are instead handled through depreciation.

Calculating the Allowable Deduction

The tax rules provide for a combination of an immediate deduction and long-term amortization for both start-up and organizational costs, with each category calculated separately. In your first year of operation, you can elect to deduct up to $5,000 of start-up costs and, if applicable, up to $5,000 of organizational costs.

Each of these $5,000 first-year deductions is subject to a phase-out. The deduction for a category is reduced dollar-for-dollar if your total costs for that category exceed $50,000. If your costs in either category reach $55,000 or more, you cannot take an immediate deduction for that category, and all of those specific costs must be amortized.

Any costs not deducted in the first year must be amortized, or spread out, over a period of 180 months (15 years). This period begins in the month that your active trade or business begins. To calculate the monthly amortization, take the total remaining costs for a category and divide them by 180. For the first year, you multiply this monthly amount by the number of months your business was operational.

For example, a business with $15,000 in start-up costs that opened on July 1 can deduct the first $5,000 immediately. The remaining $10,000 is amortized over 180 months, resulting in a monthly amount of $55.56 ($10,000 / 180). Since the business operated for six months, the first-year amortization is $333.36 ($55.56 x 6). The total first-year deduction for start-up costs would be $5,333.36 ($5,000 + $333.36). A separate calculation would be performed for any organizational costs.

Required Information and Form Completion

The election to deduct and amortize these costs is made on Form 4562, Depreciation and Amortization. You will need to know the total amount of your qualifying costs and the exact date your business began active operations. This date determines the start of the 180-month amortization period and how many months you can claim in the first year.

To complete the form, you will focus on Part VI, “Amortization.” In this section, you will enter a description of the costs on separate lines, such as “Business Start-Up Costs” and “Organizational Costs.” For each, you must enter the date the amortization period begins, the total amount of costs to be amortized, the 180-month amortization period, and the calculated amortization deduction for the current year.

Reporting the Deduction on Schedule C

After you have calculated your total allowable deduction on Form 4562, the final step is to report this amount on Schedule C (Form 1040), Profit or Loss from Business. The total deduction, which includes the immediate deduction and the first-year amortization, is transferred from Form 4562 to your Schedule C.

The deduction is reported in Part V of Schedule C, designated for “Other Expenses.” You will write in a description on one of the blank lines, such as “Amortization,” and enter the total deduction amount calculated from Form 4562.

You must attach the completed Form 4562 to your tax return, as failing to do so can lead to the disallowance of your deduction. For all subsequent tax years, you will continue to file Form 4562 to claim the annual amortization deduction until the full 180-month period is complete.
