Higher maximum rate

The pre-election Biden tax plan would raise the top individual federal income rate on ordinary income and net short-term capital gains back to 39.6%, the top rate that was in effect before the Tax Cuts and Jobs Act (TCJA) lowered it to 37% for 2018-2025. Biden also said he would generally raise taxes on folks with incomes above $400,000 without supplying specifics.

2. Itemized deductions

Biden has said he would limit the tax benefit of itemized deductions to 28% for upper-income individuals. In other words, each dollar of allowable itemized deductions could not lower your federal income tax bill by more than 28 cents, even if you are in the proposed 39.6% maximum tax bracket.

For upper-income individuals, Biden would reinstate the pre-TCJA rule that reduces total allowable itemized deductions above the applicable income threshold. Allowable deductions are reduced by 3 cents for every dollar of income above the threshold.

Biden would eliminate the TCJA’s $10,000 cap on itemized deductions for state and local taxes.

6. Elimination of real-estate tax breaks

The Biden tax plan would: (1) eliminate the $25,000 exemption from the passive loss rules for rental real estate losses incurred by middle-income individuals, (2) eliminate Section 1031 like-kind exchanges that allow deferral of capital gains taxes on swaps of appreciated real property, (3) eliminate rules that allow faster depreciation write-offs for certain real property, and (4) eliminate qualified business income (QBI) deductions for profitable rental real estate activities.
