Key Takeaways

  • Even if an S corporation has no income, it may still need to file Form 1120-S and issue Schedule K-1s to shareholders.
  • The IRS expects filings if the business had any financial activity, such as paying expenses or holding assets.
  • Ordinary and necessary expenses (like rent, utilities, startup costs, and professional fees) are deductible if the business is considered active.
  • Shareholders can often deduct losses on their personal tax returns if they have sufficient basis in the company.
  • Accurate recordkeeping and reimbursement policies are critical for substantiating deductions in an S-corp with no income.
  • Failure to file, even with no income, can result in penalties or loss of S-corp status.

Understanding all relevant s corp business expenses can help you plan ahead. This is why you need to maintain accurate records regarding all associated expenses and income. In turn, these expenses can be passed to the company's shareholders, reducing the amount of taxes they owe on their personal tax returns. 

S Corporation Defined 

An S corporation is a business entity that is limited to a maximum of 100 shareholders. By following certain restrictions, this type of business can be treated as a “pass-through” entity for tax purposes. In comparison to a C corporation, an S corporation is not taxed on its yearly earnings. Instead, all income and expenses are distributed among the S corporation's shareholders. 

These shares are based on ownership percentage. Based on each person's share, he or she will then report this activity on an individual tax return. In terms of taxation, an S corporation can either be a limited liability company or a corporation that has made a subchapter S election. Deductible expenses are then used to either decrease the shareholders' taxable income or are applied as credits for individual owners. 

S Corporation Tax Reporting 

For an individual to claim deductions, the S corporation must file a 11205. This will notify the IRS of the S corporation's annual activity. In addition, each shareholder must be given a K-1. This document details each shareholder's shares of the expenses and overall income. At the end of the K-1, shareholders will find detailed instructions to correctly report all S corporation income and expenses. 

This is an ideal business structure that allows a small business to operate as a separate entity. In turn, the business does not need to pay taxes at the corporate level. By maximizing deductions, you can save immensely on your taxes. 

When to File an S-Corp Return with No Income

An S corporation must typically file a Form 1120-S each year, even if it reports no income but expenses. The IRS considers an entity “active” if it incurred costs, paid employees, or maintained assets during the tax year. If your S-corp did not engage in any business activity—no income, no expenses, and no bank transactions—you may be able to skip filing. However, this is rare, as most businesses have at least minimal operational costs such as bank fees, state filing fees, or insurance.

Even with zero revenue, filing demonstrates that the S-corp remains compliant and helps maintain good standing with both the IRS and the state. It also prevents potential penalties for failure to file an informational return under IRC §6037.

Deductions and S Corporations 

The challenge when completing a K-1 for an S corporation is to determine whether expenses will be used as deductions on individual tax returns or to calculate the net income of the S corporation. For K-1 purposes, ordinary business income is stated on line 20 of the company's 1120S. 

Business owners are aware that they need to spend money in order to make money. However, not all are aware that spending that money can bring additional benefits. As your business grows, the money you spend can be deducted from your business income. For example, an S corporation can subtract everything from advertising to rent, taxes to employee benefits. 

Common S-Corp Expenses Without Income

Even if an S corporation didn’t generate revenue, it can often deduct ordinary and necessary business expenses incurred to maintain or prepare for operations. These may include:

  • Startup and organizational costs (legal fees, state filings, licenses)
  • Office rent and utilities
  • Professional services (accounting, consulting, legal fees)
  • Business insurance premiums
  • Marketing or website setup costs
  • Equipment depreciation

These deductions can result in a net operating loss (NOL), which may be passed through to shareholders and used to offset personal income—subject to basis limitations and at-risk rules under IRC §§1366 and 465.

However, if the IRS determines your business is not truly active (for example, still in the planning stage with no intent to earn income soon), it may classify it as a hobby or inactive entity, disallowing deductions beyond startup costs.

Consult the Experts 

If you would like to form an S corporation, it is recommended that you seek legal advice. An attorney can help ensure that all of the required documentation is filed with the right agencies — both at the state and federal levels. If you currently own an S corporation or are a shareholder, it is recommended that you hire a certified accountant to ensure compliance. 

Compliance Risks for Non-Filing S Corps

Failing to file an S-corp return—even with no income—can trigger IRS penalties of $220 per shareholder, per month, for up to 12 months. Continued noncompliance may also lead to revocation of S-corp status.To avoid issues:

  • File Form 1120-S annually, even with no income.
  • Ensure state annual reports and franchise taxes are up to date.
  • Keep copies of all receipts, reimbursement forms, and minutes to demonstrate business activity.

If you’re unsure whether your corporation needs to file or how to treat expenses with no revenue, consulting a tax attorney or CPA can help you avoid costly errors and preserve your pass-through status.

Reimbursement of Expenses Required 

If you have paid expenses that should be claimed by your S corporation, you can be reimbursed. Keep all associated receipts and turn them over to the company. If you are regularly paying for expenses yourself, then you should seek an expense reimbursement claim form. Beware that if you do not submit these expenses to the company, you will not be able to claim them on your personal tax return.

Accountable Plans and Owner Reimbursements

An S-corp shareholder who personally pays for business expenses cannot simply deduct them on their individual return. Instead, the corporation must have an accountable plan—a formal reimbursement policy that allows repayment for legitimate business costs.To qualify as an accountable plan:

  1. The expense must have a business purpose.
  2. The shareholder must document and submit receipts or logs.
  3. Any excess reimbursement must be returned to the company.

Without an accountable plan, reimbursements are treated as taxable income to the shareholder. Maintaining a written policy and timely records ensures the IRS views the payments as legitimate S-corp business expenses rather than disguised compensation.

How to Consider Business Expenses as Deductible? 

Business expenses are typically considered to be deductible as long as these conditions are met:

  • The expenses were necessary in order to conduct business 
  • You have kept all associated records to prove your claims to the IRS
  • The expense amount needs to be reasonable based on your circumstances 

When it comes to your corporation's business expenses, it is important to plan ahead and remain organized. Have a dedicated place where you store all physical records, and, for large expenses, also keep a digital copy. That way, when the time comes to file your taxes, you are not scrambling. In addition, the more organized you are, the more deductions you will be able to claim. In turn, this can help you save a significant amount of money. And remember, if you have any questions, it is recommended that you seek a professional opinion. 

Loss Limitations and Carryforwards

When an S-corp has expenses exceeding income, the resulting losses pass through to shareholders. However, the IRS limits how much can be deducted each year based on:

  • The shareholder’s stock and debt basis in the S-corp
  • At-risk limitations under §465
  • Passive activity loss rules

If losses exceed the shareholder’s basis, they are suspended and carried forward until sufficient basis is restored. This prevents owners from claiming losses beyond what they have personally invested or guaranteed.

Additionally, some startup and organizational costs can be amortized over time rather than deducted immediately. For example, up to $5,000 in startup costs can be deducted in the first year, with the remainder amortized over 15 years under IRC §195.
