New Partnership Audit Rules and Tax Law Changes


There have been two major pieces of legislation signed into law that affect each individual and entity.  The first is the Bipartisan Budget Act of 2015 (“BBA”) which became effective as of January 1, 2018, and the second is the Tax Cuts and Jobs Act of 2017 (“TCJA”) which applies for tax years beginning after December 31, 2017 (and in many instances ending before January 1, 2026).[1]  This letter will give a general overview of the changes that may affect you, but you should consult with your attorney or other tax professional for an in depth determination of whether or not you need to take any immediate action.

BBA Changes to Entities Taxed as a Partnership: The BBA repealed and replaced the 1982 Tax Equity and Fiscal Responsibility Act (also known as “TEFRA”). The BBA institutes new rules that focus on partnership-level determinations, assessments, and collections of tax.  The BBA will force most entities taxed as a partnership, including limited liability companies, to amend their partnership agreements or company agreements in order to comply with the new law.  You should consult with your attorney or other tax professional to determine if your partnership agreement or company agreement should be amended.

Tax Changes under the TCJA regarding Individuals:

  • Standard Deduction – taxpayers are allowed to reduce their adjusted gross income (“AGI”) by the standard deduction. The TCJA increased the standard deduction to $24,000 for married individuals filing jointly (up from $13,000), $18,000 for head-of-household filers (up from $9,550), and $12,000 for single individuals and married individuals filing separately (up from $6,500).
  • Tax Brackets – the TCJA applies seven new tax brackets for individuals: 10%, 12%, 22%, 24%, 32%, 35%, and 37%.
  • Personal Exemptions Suspended – prior to the TCJA, taxpayers determined their taxable income by subtracting from their AGI any personal exemption deductions. After the TCJA, the deduction for personal exemptions is effectively suspended.
  • Kiddie Tax – the TCJA made modifications to the taxable income of a child attributable to earned income and net unearned income.
  • Capital Gains – the TCJA generally retains the pre-TCJA rates, but indexes them for inflation.

  • Carried Interest – the TCJA imposes a three year holding period in order for certain interests received in connection with the performance of services to be taxed as a long-term capital gain rather than ordinary income.
  • Limitations of “Excess Business Loss” – the TCJA provides that the excess farm loss limitation does not apply and instead a non-corporate taxpayer’s “excess business loss” is disallowed. Such excess business losses are not allowed for the tax year but are instead carried forward and treated as part of taxpayer’s net operating loss carry forward in subsequent tax years.
  • Personal Casualty & Theft Losses – the personal casualty and theft losses deduction may be suspended, except for personal casualty losses incurred in a Federally declared disaster.
