For 2018-2025, you (and estates and trusts) can use your qualified business income (QBI) to create the 20 percent deduction under Section 199A.
While federal income tax losses from business activities are usually beneficial, losses from pass-through business entities can have the adverse side effect of reducing allowable QBI deductions for pass-through business entity owners—such as you.
In this context, pass-through entities are defined as sole proprietorships, single-member (one owner) LLCs treated as sole proprietorships for federal income tax purposes, partnerships, multimember LLCs treated as partnerships for federal income tax purposes, and S corporations.
These entities can pass through business losses that you can deduct in the current year. But a pass-through of a loss could harm your QBI for the current year.
Or you may have to suspend the losses and carry them forward to future years. The suspended losses can also result in negative QBI in the year you deduct them.
If you own multiple businesses and/or rental properties, the Section 199A deduction can get complicated. If you would like my help sorting this out for you, please don’t hesitate to
