Tax policy is likely to remain fractious and highly partisan, with Republicans focused on extending business and individual tax preferences that expire in 2025, and Democrats focused on provisions for lower-income taxpayers, such as the refundable child tax credit and earned income tax credit.

Key legislation includes the expiring 2017 Tax Cuts and Jobs Act provisions, the child tax credit, earned income tax credit and international tax reforms.

Areas for bipartisan cooperation in near term do exist, but are limited to smaller items such as pension reform, disaster relief, and perhaps tax extenders.

Republicans will likely:

• Remain focused on making items in the 2017 Tax Cuts and Jobs Act permanent.

• Attempt to reverse certain business tax increases, such as amortizing R&D expenses, that went into effect this year.

• Attempt to use the annual appropriations process to roll back IRS enforcement funding or place new limits on the use of the funds.

• Conduct oversight aimed at IRS leaks of confidential taxpayer information, such as the leak to ProPublica.
