Individual Tax Preparation for Business Owners

Personal Tax Returns for S Corporation Owners

Owning an S corporation creates a direct connection between your business tax return and your personal Form 1040.

Your personal return may include W-2 wages from the corporation, Schedule K-1 income or loss, shareholder distributions, health insurance, retirement contributions and other items that originate with the business.

TaxReturn.cpa prepares the individual side of the equation, backed by a CPA firm that also understands business taxation.

Your S Corporation and Your Personal Return Are Separate — But Connected

An S corporation generally files its own federal income tax return on Form 1120-S. The corporation then provides each shareholder with a Schedule K-1 reporting that shareholder's share of relevant tax items.

The S corporation generally does not pay federal income tax on its ordinary business income at the entity level. Instead, taxable items generally pass through to the shareholders and are reported on their individual returns.

That means your business return may be finished first, but the tax story is not finished until the relevant information has been incorporated into your personal return.

What From Your S Corporation Can Affect Your Personal Tax Return?

K-1 Income and S Corporation Distributions Are Not the Same Thing

This is one of the most important concepts for an S corporation owner to understand.

You can owe income tax on S corporation income even if the business did not distribute that amount of cash to you. Your share of pass-through taxable income is generally determined by the corporation's tax results, not simply by how much money you withdrew.

Conversely, a shareholder distribution is not automatically additional taxable income. Its treatment can depend on factors including your stock basis and the corporation's tax history.

For a deeper discussion of the information reported to you from a pass-through business, see our K-1 Tax Preparation page.

Why Shareholder Basis Matters

Shareholder stock and debt basis can become important when an S corporation reports losses or makes distributions to its owners.

Basis generally changes over time as the shareholder contributes capital, receives pass-through income, incurs pass-through losses and deductions, and receives distributions.

A loss appearing on Schedule K-1 is therefore not automatically deductible on the personal return. Basis limitations apply before other potential loss limitations are considered.

Likewise, distributions can have different tax consequences when they exceed the shareholder's available stock basis.

An S Corporation Loss Does Not Automatically Mean a Personal Tax Deduction

When an S corporation reports a loss, several tax rules can affect whether the shareholder may currently deduct that loss.

Depending on the circumstances, the return may need to consider shareholder basis, at-risk limitations, passive activity limitations and other individual-level limitations.

A loss that cannot be deducted currently may potentially be suspended for use in a later year if the applicable requirements are eventually satisfied.

What About Your S Corporation Salary?

An S corporation shareholder who performs services for the corporation may also be an employee of the corporation.

Wages paid through payroll are different from pass-through income reported on Schedule K-1. The wages appear on Form W-2 and are generally subject to employment taxes, while the shareholder's pass-through business income follows separate tax rules.

The IRS also requires shareholder-employees to consider reasonable compensation for services performed before treating payments as non-wage distributions.

Health Insurance for More-Than-2% S Corporation Shareholders

Health insurance for a shareholder who owns more than 2% of an S corporation has special reporting rules.

When the applicable requirements are met, health insurance premiums paid or reimbursed by the S corporation are generally included in the shareholder-employee's Form W-2 wages for income-tax reporting, while the shareholder may potentially qualify for the self-employed health insurance deduction on the individual return.

This is a good example of why the business payroll records and personal tax return should not be viewed as completely separate systems.

S Corporation Owners May Need Estimated Tax Payments

Income tax generally is not withheld from the pass-through income reported on your Schedule K-1.

Your W-2 withholding may cover some or all of your individual tax obligation, but business profitability can cause the amount owed on the personal return to increase substantially.

Depending on your overall tax situation, estimated tax payments or increased payroll withholding may need to be considered during the year rather than waiting until the tax return is filed.

What if Your S Corporation Does Business in Multiple States?

An S corporation operating in more than one state can create additional individual filing considerations for its shareholders.

Your K-1 package may contain state schedules allocating or apportioning income to jurisdictions where you do not live. Those schedules need to be considered when determining whether additional nonresident individual returns are required.

Learn more on our CPA for Multi-State Tax Returns page.

What if You Also Need the S Corporation Tax Return Prepared?

TaxReturn.cpa is focused specifically on individual income tax preparation.

If your Form 1120-S has already been prepared, we can use the resulting Schedule K-1 and related information when preparing your personal return.

If you need both the S corporation return and your personal return prepared, business tax preparation is available separately through Boulanger CPA and Consulting PC.

Keeping the services distinct lets TaxReturn.cpa maintain a streamlined individual tax process while still giving business owners access to broader CPA-firm services when needed.

What We Review for an S Corporation Owner's Personal Return

Depending on your situation, we may review:

• Your complete Schedule K-1 and supplemental statements
• W-2 wages from the S corporation
• Shareholder distributions
• Relevant shareholder basis information
• Prior-year suspended losses when applicable
• More-than-2% shareholder health insurance reporting
• Retirement plan information affecting the individual return
• State K-1 schedules and multi-state activity
• Estimated tax payments
• Other income, deductions and credits on your individual return

If the underlying business return contains unresolved issues or the shareholder basis records need substantial reconstruction, additional work or a separate engagement may be necessary before the individual return can be completed.

How Much Does Personal Tax Preparation Cost for an S Corporation Owner?

Owning an S corporation does not by itself determine the price of your personal return. We look at the overall complexity of the 1040.

A straightforward W-2 and K-1 return is different from a return involving multiple businesses, rental properties, investment activity, several states or complex loss limitations.

Frequently Asked Questions for S Corporation Owners

Does my S corporation file a separate tax return from me?

Yes. An S corporation generally files Form 1120-S. The shareholder then receives a Schedule K-1 containing information that may need to be reported on the shareholder's individual tax return.

Do I pay tax on my K-1 or on the distributions I received?

They are different concepts. S corporation taxable income generally passes through to shareholders whether or not the corporation distributes an equal amount of cash. Distributions have separate tax rules and can be affected by shareholder basis.

Can I deduct an S corporation loss shown on my K-1?

Not automatically. Basis, at-risk, passive activity and other limitations may need to be considered before determining whether the loss is currently deductible.

Why do I receive both a W-2 and a K-1 from my own company?

They report different items. Your W-2 reports wages paid to you as an employee, while your Schedule K-1 reports your share of pass-through tax items as a shareholder.

Can TaxReturn.cpa prepare my S corporation return too?

TaxReturn.cpa is focused on individual income tax returns. Business return preparation, including Form 1120-S, is available separately through Boulanger CPA and Consulting PC.

What if my S corporation K-1 is not ready by April?

An individual tax return generally should not be finalized without required K-1 information. Filing an extension can provide additional time to file while waiting for the information. An extension gives additional time to file, not additional time to pay. Learn more on our Tax Return Extensions page.
