One of the biggest misconceptions I see as an Enrolled Agent is that people think…“I have an LLC… so I file a separate business tax return, right?”
Not necessarily.
Your tax return is based on how your business is taxed—not the name of your business structure, or the fact that it is a business. By the end of this article, you’ll know exactly which tax forms your LLC business should be filing — and whether your business and personal taxes are filed together or separately.
Let’s break it down.
Sole Proprietor (No LLC)
If you operate under your own name and have not formed a separate legal entity with your state, you are automatically considered a sole proprietor. This is true even if you never called yourself a business.
For tax purposes, there is no separate business return. You file one personal tax return — Form 1040 — with a Schedule C attached. Schedule C is not a separate return. It is simply an additional form included with your 1040 to report your business income and expenses.
Your net profit from Schedule C flows onto your Form 1040 and is subject to:
- Income tax
- Self-employment tax
For those of you who received a 1099-NEC for freelance, contract, side, or gig work, the IRS considers you self-employed, which means you are operating as a sole proprietor by default.
Single-Member LLC (Default Tax Treatment)
If you operate under your own name or a registered business name and have formed a separate legal entity with your state, you are considered a single-member LLC. However, for federal tax purposes, a single-member LLC is treated as a disregarded entity by default. That means the IRS does not see your LLC as separate from you for income tax purposes. They “disregard” the entity and treat you and the business as the same taxpayer.
So you still file one personal tax return — Form 1040 — with a Schedule C attached. Again, the Schedule C is simply an additional form included with your 1040 to report your business income and expenses. It is not a separate business tax return.
The LLC exists for legal protection at the state level, but unless you elect to be taxed differently, the IRS taxes it like a sole proprietorship.
That’s the part most people miss. Having an LLC does not automatically mean you file a separate return.
Multi-Member LLC (Default Tax Treatment = Partnership)
If your LLC has more than one owner, the default tax treatment is a partnership.
Unlike a sole proprietor or single-member LLC, a multi-member LLC does file a separate business return. The business files Form 1065 (U.S. Return of Partnership Income) to report the company’s total income and expenses for the year. However, the partnership itself does not pay income tax.
Instead, the profit (or loss) is divided among the owners based on their ownership percentages. Each owner receives a Schedule K-1, which shows their share of the business income. That amount is then reported on their personal tax return.
So while there is a separate partnership return filed, the tax is still paid at the individual level. The income “passes through” the business to the owners.
Tax Elections Change the Return You File
Everything we’ve discussed so far applies to the default tax treatment — meaning no special election was filed with the IRS. But business owners do have the option to choose a different tax classification. When that election is made and approved, the return you file changes.
Here’s how that works.
LLC Taxed as an S Corporation (Election Required)
An LLC can choose to be taxed as an S corporation in order to create tax planning opportunities and potentially lower overall tax liability. This is done by filing Form 2553 (Election by a Small Business Corporation) with the IRS and having it approved.
Once that election is in place, the business files Form 1120-S each year. The company reports its income and expenses on that return, and each owner receives a Schedule K-1 showing their share of the profit.
S corporations require ongoing compliance and administrative responsibility.
If you actively work in the business, you are generally required to pay yourself a reasonable salary through payroll. That means:
- Running payroll
- Making payroll tax deposits
- Filing payroll reports
- Issuing W-2 forms at year’s end
An S corporation can create tax savings when its profits support it. But it is not just a tax label — it is a structure that requires proper setup, maintenance, and consistent compliance to avoid penalties.
LLC Taxed as a C Corporation (Election Required)
An LLC can also choose to be taxed as a C corporation in order to operate as a separate corporate taxpayer and potentially take advantage of corporate tax strategies. This is done by filing Form 8832 (Entity Classification Election) with the IRS and having the election approved. Once approved, the LLC is treated as its own taxable entity.
The business then files Form 1120 each year and pays corporate income tax at the entity level.
Here’s where it differs from a default LLC. With a single-member LLC or partnership, income flows through to the owner’s personal return. With a C corporation, the corporation pays its own tax first. If the owner later takes money out as dividends, those dividends are reported on the owner’s personal tax return and may be taxed again. That’s what people are referring to when they talk about “double taxation.”
C corporations can make sense in certain situations — especially when profits are being retained in the business or when outside investors are involved. But like an S corporation, this structure comes with increased compliance, corporate formalities, and separate tax reporting responsibilities. It’s not just a checkbox. It’s a commitment to operating as a corporation for tax purposes.
The Bottom Line
Whether you file your LLC and personal taxes together depends on how your business is taxed — not simply whether you have an LLC or business.
Your LLC is a legal structure.
Your tax election determines how you file and which return you file.
It comes down to:
- How many owners do you have
- Whether you filed a tax election
- How the IRS currently recognizes your entity
I’ve seen business owners file two returns when they didn’t need to — and I’ve seen others miss required filings because they didn’t realize their LLC was being taxed as a partnership or corporation. That’s how penalties and IRS letters start.
If you’re unsure, don’t guess during tax season.
Before filing, make sure you understand how your business is classified for tax purposes. Filing the wrong return — or failing to file a required one — can create problems that are much more expensive to fix later.
