Prepare a P&L Statement.

Your P&L (or income statement) shows how much your business earned and spent over the year. It’s the foundation for your business tax return — and helps you see your profitability at a glance.

You’ll use it to:

Confirm your business type

Many new businesses form as LLCs. For tax purposes, the IRS looks at how your LLC is structured — single owner, multiple owners, or if you’ve elected S-corp or C-corp status.

Sole ProprietorsSelf-employed individuals or single-member LLCs that haven’t elected another statusSchedule C (Form 1040)
PartnershipMulti-member LLCs or general partnershipsForm 1065, Schedule K-1

Review & file confidently

Once you’ve entered your business information, you’ll see a clear summary of your results — what you earned, what you can deduct, and what you owe. TaxAct checks for accuracy, helps you spot potential savings, and makes it easy to file securely.
