Schedule L: Transactions with Interested Persons Definition

What Is Schedule L: Transactions with Interested Persons?

Schedule L is a tax schedule attached to IRS Form 1040 that is used to calculate the standard deduction for certain tax filers. Schedule L is only used by taxpayers who are increasing their standard deduction by reporting state or local real estate taxes, taxes from the purchase of a new motor vehicle, or from a net disaster loss reported on Form 4684.

Schedule L is also used for those who file Form 990 or Form 990-EZ to provide information about the financial transactions and arrangements between the organization that filed the forms and disqualified persons under section 4958, or other interested persons. Schedule L is also used to distinguish members of an organization's governing body as independent members. 

Key Takeaways

  • Schedule L is a form attached to U.S. income tax returns used to calculate a taxpayer's standard deduction.
  • Most taxpayers who use the standard deduction instead of itemizing do so because they don't have to keep track of qualifying expenses or they don't have enough items to deduct.
  • Not all taxpayers qualify for the standard deduction.
  • Schedule L may also be used for organizations in conjunction with Form 990.

Understanding Schedule L: Transactions with Interested Persons

Schedule L is necessary because refunds and rebates already received on real estate taxes reduce the amount of additional standard deduction for which a taxpayer may be eligible. The standard deduction is the portion of income that is not subject to tax that can be used to reduce your overall tax bill. With regards to motor vehicles, taxpayers in states that do not charge sales tax but levy another fee on the purchase of a new vehicle can treat those fees as a tax for the purpose of this form. Taxpayers should check to see if an increased standard deduction will provide the same tax benefit as itemizing deductions.

Schedule L is also used to report partnership income to the IRS. So, for example, if you are part of a business partnership that distributes incomes to its members, federal tax law dictates that the partnership is not taxed on the profit, but the partners report the income on their own individual returns. Form 1065 is used to first declare business partnership income to the IRS and then Schedule L is used to detail the specifics of the partnership balance sheet.

The balance sheet includes all business assets, equity, and capital, as well as liabilities and it provides a financial overview of the business. The balance sheet also dictates if any other forms are required based on the total financial amount, as more paperwork is needed if the total partnership assets exceed a total of 10 million dollars.
