Tax Reform Update for Dental Practices

Tax Reform Impact on Dental Practices

Filed under:


On December 22, 2017, H.R. 1, formerly referred to as the Tax Cuts and Jobs Act of 2017 (TCJA) was signed into law.  This tax law will affect individuals, all types of business, tax-exempt entities, international taxation, and many other areas of tax law.

Although the act is final, there is still a significant amount of guidance needed before we can really understand all of 2017 tax reform, and not all of the provisions are considered permanent.  Many of the provisions will expire after December 31, 2025 or another point in time, and caution should be taken when considering drastic changes in tax strategies or entity structuring.

Below is a summary of some of the tax provisions affecting taxpayer’s and business and how they compare to pre-tax reform law. It is important that you are talking with your tax advisor about the potential planning opportunities available to you, and how the changes could impact your tax liability for 2018.


Individual Pre-Tax Reform Law Tax Reform 2017 Comments
Individual rates Seven brackets under 2017 tax law were as follows; 10%, 15%, 25%, 28%, 33%, 35%, and 39.6% Seven brackets under reform are as follows; 10%, 12%, 22%, 25%, 32%, 35% and 37%.  These brackets expire after 2025 tax year. Taxpayers will see rate cuts and higher income limits at most brackets.
Standard deduction Deduction is $6,350 for single, $9,350 for HOH and $12,700 for joint return. Increased to $12,000 (single), $18,000 (HOH), and $24,000 (joint), and indexed for inflation before reverting to current law in 2026. The increased standard deduction will help those that do not itemize, but will likely not benefit those that historically have itemized.
Personal exemption For 2017, taxpayer’s may deduct $4,050 for each personal exemption. Personal exemption suspended for tax years beginning after 12/31/17 and before 1/1/26. The loss of personal exemptions is being offset for those in “lower” bracket by the increased standard deduction.
Child credit $1,000 tax credit for each child under the age of 17.  Tax credit phased out starting at $75,000 of income for single and $110,000 for joint. Tax credit increased to $2,000 with higher phase-out threshold beginning at $400,000 for joint and $200,000 for other taxpayers. The increased credit and threshold will benefit many taxpayers.  Provision effective for tax years beginning after 12/31/17 and before 1/1/26.
Alternative minimum tax (AMT) Taxpayers must compute their regular tax, and their AMT.  Tax liability will be the greater of their regular tax or their AMT. For tax years beginning after 12/31/17 and before 1/1/26, AMT retained and the AMT exemption and phase out of exemption. The increased exemption, the increased phase-out, and the limiting of state income tax deductions will potentially result in fewer being subject to AMT.
State and local tax deduction Individuals may claim the state and local income or sales tax as an itemized deductions. Individuals may deduct state and local sales, income, or property taxes up to $10,000 for tax years after 12/31/17 and before 1/1/26. Oregon residents (not in AMT) will be negatively impacted by this provision because of high state income taxes.
Mortgage interest Taxpayer can deduct interest on $1M of acquisition indebtedness and up to 100,000 in home equity indebtedness. Reduces mortgage interest to interest on $750,000 of acquisition indebtedness for debt after 12/15/17.  Pre-tax reform debt is exempt from new limit.  Mortgage interest on home equity has been suspended. Provisions revert back after 12/31/25.
Charitable contribution For 2017 and after 2025, cash contributions to public charities deductible up to 50% of AGI. Donations to for the right to purchase tickets are 80% deductible as charitable.


Tax reform increased AGI limit on cash donations to public charities to 60% for years after 2017 and before 2026. Tax reform repeals 80% deduction for donations made for athletic seating rights. Taxpayers will lose the deduction for seating rights unless prepaid at the end of 2017.  Charitable venture funds may be more attractive due to deduction and Oregon tax credit.
Alimony Above-the-line deduction for amounts paid, and taxable income to the recipient. Act eliminates the current above-the-line deduction for alimony payments and not taxable to the recipient. The provision is effective for divorces beginning after 12/31/18.



Corporate/Business Pre-Tax Reform Law Tax Reform 2017 Comments
Alternative minimum tax (AMT) C corporations subject to AMT if average annual gross receipts over $7.5M for preceding three years. Corporate AMT repealed beginning with 2018 tax year.  Prior year minimum tax credit allowed to offset regular tax liability.  No expiration Many small businesses are not subject to AMT, but many will benefit from the repeal of AMT.
Corporate tax rate Corporate tax brackets as follows; 15%, 25%, 34%, and 35% with phase-out of lower rates if corporation exceeds certain taxable income thresholds.  Personal service corporations a flat 35% tax rate. Corporate tax rate a flat 21% rate effective for 2018 tax year. Personal service corporations (covers healthcare, accounting, and other service-based industries) do not have a special rate, they are also taxed at 21%.

Reduces to 80% for 2023, 60% for 2024, 40% for 2025, and 20% for 2026. For small business owners, there is not much of a beneficial difference between cost recovery and Section 179 (see below).

Section 179 expensing In 2017, Businesses may expense up to $510K, expensing limited when assets placed in service in the current year exceeds $2.03M, or based on businesses taxable income. Expensing increased to $1M ($2.5M phase-out threshold).  Expands definition for eligible property to include qualified improvement property and certain improvements (roofs, HVAC, fire alarm, and security system) to nonresidential property.  The expansion of additional property will be beneficial as well as the increased limits.  Oregon business owners will need to plan for their depreciation deduction.  Oregon, among others states, will likely not follow Federal which will create differences.
Business interest expense Business interest is generally allowed as a deduction in the year it is paid or accrued. Interest deduction limited to 30% of business adjusted taxable income.  Businesses with average annual gross receipts of $25M or less are exempt.  Disallowed interest is carried forward indefinitely.
