2018 Tax Changes

The Tax Cuts and Jobs Act Suspended or Repealed Certain Rules and Deductions

Beginning January 1, 2018, the following items have been eliminated:

  • Miscellaneous itemized deductions subject to the 2%-of-adjusted-gross-income floor
  • Personal and dependency exemptions
  • Moving expenses except for certain active duty military personnel
  • Exclusion for bicycle commuting
  • Phaseout of itemized deductions

Beginning 2018 All Taxpayers Must Use Form 1040

All taxpayers must use Form 1040 for 2018; Forms 1040A and 1040EZ have been eliminated. Form 1040 has been redesigned and is supplemented by new Schedules 1 through 6.

Schedule 1:

Schedule 1 is used to report income or adjustments to income that can’t be entered directly on Form 1040.

Additional income is entered on Schedule 1, lines 1 through 21. These are generally the same items that were listed in the 2017 income section of Form 1040 in 2017.

Adjustments to income are entered on Schedule 1, lines 23 through 36. These are generally the same items were listed in the 2017 Adjusted Gross Income section of Form 1040.

Add the amounts on Form 1040, lines 1, 2b, 3b, 4b, and 5b, and the amount on Schedule 1, line 22, and enter on Form 1040, line 6.

If you have adjustments to income, subtract the amount on Schedule 1, line 36, from the amount on Form 1040, line 6, and enter on Form 1040, line 7.

Qualified Business Income (QBI) Deduction (Code Sec. 199A)

Beginning 2018, a provision in the Tax Cuts and Jobs Act (sec. 199A) allows a deduction of up to 20% for certain domestic qualified business income (QBI) from pass-through entities (sole proprietorships, partnerships, limited liability companies, and S corporations). The QBI deduction is taken by sole proprietors, partners, S corporation shareholders, estates and trusts. The QBI deduction does not apply to C corporations.

In addition, you may also be entitled to add to the QBI deduction up to 20% of combined qualified REIT dividends and qualified publicly traded partnership (PTP) income.

The QBI deduction is subtracted from adjusted gross income on Form 1040. It is not deducted from business income and it is not an adjustment to gross income in figuring adjusted gross income. However, since this deduction is subtracted from adjusted gross income, those claiming the standard deduction or itemized deductions may claim this deduction.

Part of the justification for providing this tax benefit to non-C corporation businesses was the significant tax rate reduction for C corporations, from a maximum graduated rate of 35% to a flat 21% rate.

Entertainment Expenses

For 2018 and beyond, the TCJA eliminated the deduction for any expenses related to activities generally considered entertainment, amusement or recreation. For example, taking a client or potential client to a ball game or to a dinner-theater.

However, taxpayers may continue to deduct 50% of the cost of business meals if:

  • the taxpayer (or an employee of the taxpayer) is present
  • the food and/or beverages are not considered lavish or extravagant and
  • the food and beverages are purchased separately, or shown on the bill separately from the cost of the entertainment.

2018 IRS Mileage Allowance

  • Business: 54.5 cpm
  • Medical: 18 cpm
  • Moving: 18 cpm (see Note below)
  • Charitable: 14 cpm

Note: Moving Expenses Under the Tax Cuts and Jobs Act (TCJA):

Only members of the U.S. Armed Forces on active duty who move pursuant to a military order and incident to a permanent change of station may deduct unreimbursed moving expenses for 2018 and later years . These qualifying Armed Forces members are also the only taxpayers who may exclude employer allowances or reimbursements for eligible moving expenses.

Form 3903 is used to report deductible moving expenses. The excess of deductible moving expenses over excludable government allowances or reimbursements, as shown on Form 3903, is entered as an adjustment to income on Schedule 1 of Form 1040.

2018 Vehicle Depreciation Limit and Bonus Depreciation for Vehicles

The ceiling on depreciation for a vehicle placed in service in 2018 is generally $10,000, reduced by personal use. However, if the vehicle is used more than 50% for business in 2018, the first-year dollar limit is increased by the bonus depreciation allowance to $18,000 ($10,000 plus $8,000), reduced by personal use. You can elect not to claim the bonus allowance.

Certain vehicles are exempt from the annual depreciation limits, such as an ambulance, hearse, or combination hearse-ambulance used directly in business, taxi cabs used for transporting persons or property for compensation or hire.

Depreciation Limits Under the New Law (TCJA) for Passenger Vehicles placed in service after Dec. 31, 2017:

  • If the taxpayer doesn’t claim bonus depreciation, the greatest allowable depreciation deduction is:
    • $10,000 for the first year,
    • $16,000 for the second year,
    • $9,600 for the third year, and
    • $5,760 for each later taxable year in the recovery period
  • If a taxpayer claims 100 percent bonus depreciation, the greatest allowable depreciation deduction is:
    • $18,000 for the first year,
    • $16,000 for the second year,
    • $9,600 for the third year, and
    • $5,760 for each later taxable year in the recovery period

The new law also removes computer or peripheral equipment from the definition of listed property. This change applies to property placed in service after Dec. 31, 2017.

2018 First-year expensing (Section 179), Bonus Depreciation, Farm Property, Applicable Recovery Period for Real Property

For qualifying property placed in service in 2018, first-year expensing is allowed up to a limit of $1 million. The limit begins to phase out dollar-for-dollar if the total cost of qualifying property exceeds $2.5 million.

Section 179 Deduction Phase-out:

If the cost of qualifying property placed in service in 2018 is more than $2,500,000, you reduce the $1,000,000 expensing limit dollar-for-dollar for each dollar the cost of qualifying property exceeds $2,500,000 (but not below zero).

For example, if you place machinery in service during 2018 costing $2,600,000, the $1,000,000 deduction limit is reduced by $100,000 to $900,000, which is entered on Form 4562, Line 5 of Part 1 (labeled "Dollar limitation for tax year.")

If the cost of the property was $3,500,000 or more, you could not take the Section 179 deduction because the $1,000,000 deduction limit would be completely phased out.

Bonus Depreciation:

The new law increases the bonus depreciation percentage from 50 percent to 100 percent for qualified property acquired and placed in service after Sept. 27, 2017, and before Jan. 1, 2023.

The bonus depreciation percentage for qualified property that a taxpayer acquired before Sept. 28, 2017, and placed in service before Jan. 1, 2018, remains at 50 percent. Special rules apply for longer production period property and certain aircraft.

Bonus Depreciation for Qualified Used Property:

The definition of property eligible for 100 percent bonus depreciation was expanded to include used qualified property acquired and placed in service after Sept. 27, 2017, if all the following factors apply:

  • The taxpayer or its predecessor didn’t use the property at any time before acquiring it.
  • The taxpayer didn’t acquire the property from a related party.
  • The taxpayer didn’t acquire the property from a component member of a controlled group of corporations.
  • The taxpayer’s basis of the used property is not figured in whole or in part by reference to the adjusted basis of the property in the hands of the seller or transferor.
  • The taxpayer’s basis of the used property is not figured under the provision for deciding basis of property acquired from a decedent.
  • Also, the cost of the used property eligible for bonus depreciation doesn’t include the basis of property determined by reference to the basis of other property held at any time by the taxpayer (for example, in a like-kind exchange or involuntary conversion).

The new law added qualified film, television and live theatrical productions as types of qualified property that may be eligible for 100 percent bonus depreciation. This provision applies to property acquired and placed in service after Sept. 27, 2017.

Under the new law, certain types of property are not eligible for bonus depreciation in any taxable year beginning after December 31, 2017. One such exclusion from qualified property is for property primarily used in the trade or business of the furnishing or sale of:

  • Electrical energy, water or sewage disposal services,
  • Gas or steam through a local distribution system or
  • Transportation of gas or steam by pipeline.

This exclusion applies if the rates for the furnishing or sale have to be approved by a federal, state or local government agency, a public service or public utility commission, or an electric cooperative.

The new law also adds an exclusion for any property used in a trade or business that has had floor-plan financing indebtedness if the floor-plan financing interest was taken into account under section 163(j)(1)(C). Floor-plan financing indebtedness is secured by motor vehicle inventory that in a business that sells or leases motor vehicles to retail customers.

Changes to Treatment of Certain Farm Property

The new law shortens the recovery period for machinery and equipment used in a farming business from seven to five years. This shorter recovery period, however, doesn’t apply to grain bins, cotton ginning assets, fences or other land improvements. The original use of the property must occur after Dec. 31, 2017. This recovery period is effective for eligible property placed in service after Dec. 31, 2017.

Also, property used in a farming business and placed in service after Dec. 31, 2017, is not required to use the 150 percent declining balance method. However, if the property is 15-year or 20-year property, the taxpayer should continue to use the 150 percent declining balance method.

Use of Aternative Depreciation System for Farming Businesses

Farming businesses that elect out of the interest deduction limit must use the alternative depreciation system to depreciate any property with a recovery period of 10 years or more, such as single purpose agricultural or horticultural structures, trees or vines bearing fruit or nuts, farm buildings and certain land improvements. This provision applies to taxable years beginning after Dec. 31, 2017.

Applicable Recovery Period for Real Property

The new law keeps the general recovery periods of 39 years for nonresidential real property and 27.5 years for residential rental property.

The new law changes the alternative depreciation system recovery period for residential rental property from 40 years to 30 years.

Qualified leasehold improvement property, qualified restaurant property and qualified retail improvement property are no longer separately defined and no longer have a 15-year recovery period under the new law.

These changes affect property placed in service after Dec. 31, 2017.

Under the new law, a real property trade or business electing out of the interest deduction limit must use the alternative depreciation system to depreciate any of its nonresidential real property, residential rental property, and qualified improvement property. This change applies to taxable years beginning after Dec. 31, 2017.

2018 Mortgage Interest

The deduction for mortgage interest on a principal residence and second residence is limited to acquisition debt up $750,000 ($375,000 for married persons filing separately) for loans acquired after December 15, 2017.

No deduction is allowed for interest on home equity debt, regardless of when the loan was obtained. However, this bar does not apply to the extent proceeds are used to buy, build, or substantially improve the home that secures the loan.

For example, If the loan is used to pay off credit card debt or buy a car, the interest is not deductible. If the loan is used to improve a second home, but the loan is not secured by the second home, the interest is not deductible.

2018 State and Local Taxes (SALT)

Starting in 2018, you cannot deduct more than $10,000 ($5,000 if married filling separately) of the following taxes, in any combination:

  • On Schedule A, Line 5a, you may deduct state and local income taxes or state and local general sales taxes, but not both.
  • State and local real property taxes
  • State and local personal property taxes

Example: Married couple files 2018 joint tax return. They paid the following taxes:

  • 2018 state/local income taxes withheld from their 2018 gross wages: $1,000.
  • They paid their 2017 state/local income tax liability shown on their 2017 return when they filed their 2017 return on April 15, 2018: $300
  • 2018 State and local sales tax: $1,300
  • Real estate taxes: $8,800
  • Personal property tax on two vehicles: $950
  • Total taxes paid: $12,350

Result: On Schedule A, they deduct the combination of $1,300 sales tax and $8,700 real estate taxes, for a maximum SALT deduction of $10,000. The remaining $2,350 is not deductible.

Foreign Taxes:

  • Foreign real property taxes are no longer deductible.
  • Foreign Income taxes ARE still allowed as an itemized deduction and are NOT subject to the $10,000 limit ($5,000 limit if married filing separately). However, a foreign tax credit may be a better alternative to the deduction.

2018 Standard Deduction

Your standard deduction depends on your filing status.

  • Married filing Joint return: $24,000
  • Qualifying widow(er): $24,000
  • Head of household: $18,000
  • Single: $12,000
  • Married filing separately: $12,000
  • Dependents - minimum deduction: $1,050
  • Additional Deduction if Age 65 or Older, or Blind. If you turned 65 on January 1, 2019, you are considered to be 65 as of December 31, 2018 for purposes of claiming this deduction. The larger deduction for blindness is allowed regardless of age.
    • Married-per-spouse, filing jointly or separately:
      • $1,300 ($2,600 for age and blindness)
    • Qualifying widow(er):
      • $1,300 ($2,600 for age and blindness)
    • Single or head of household:
      • $1,600 ($3,200 for age and blindness)

If you turned 65 on January 1, you are considered to be 65 as of December 31 of the previous tax year. For example, if you turned 65 on January 1, 2019, you are considered to be 65 as of December 31, 2018 and would be eligible to claim the additional standard deduction that applies to age.

Complete Blindness:

To be eligible for the additional standard deduction for blindness, you must be completely blind as of December 31. The larger deduction for blindness is allowed regardless of age.

Partial Blindness:

To claim the additional standard deduction if you are partially blind as of December 31, you will need to get a letter from your eye doctor certifying that you cannot see better than 20/200 in your better eye with lenses or that your filed of vision is 20 degrees or less. If your eye doctor believes your vision will never improve beyond these limits, this fact should be stated in the letter.

2018 Personal Exemption Deduction Suspended for yourself, your spouse, and each dependent

You can no longer claim a personal exemption for yourself, your spouse or your dependents.

2018 Earned Income Tax Credit (EIC)

Maximum EIC:

  • $3,461 for one qualifying child
  • $5,716 for two qualifying children
  • $6,431 for three or more qualifying children
  • $519 for taxpayers who have no qualifying child

The phaseout ranges for the EIC have been adjusted for inflation.

2018 Child Tax Credit and Credit for Other Dependents

For 2018, the child tax credit amount is increased, up to $2,000 per qualifying child under age 17. This credit is refundable, which means if the credit exceeds your tax liability, you get the excess amount refunded to you, within limits.

The income limits on eligibility for the credit have been increased. The credit will not begin to phase out until modified adjusted gross income (MAGI) exceeds $400,000 if married f filing jointly, or $200,000 for all others.

In most cases MAGI is the same as adjusted gross income (AG). If you claim the foreign earned income exclusion, foreign housing exclusion or deduction, or possession exclusion for American Samoa residents, these amounts must be added back to AGI to get MAGI for credit purposes. The threshold amounts will NOT be indexed after 2018 for inflation.

The maximum credit of $2,000 per qualifying child is reduced by 5% or $50 for each $1,000 (or fraction of $1,000) that your MAGI exceeds the phaseout threshold.

There is also a new nonrefundable credit up to $500 for a qualifying dependent who is not a qualifying child.

2018 Saver's Credit

The adjusted gross income (AGI) brackets for the 10%, 20%, and 50% credits are increased for 2018.

No credit is allowed when AGI reaches:

  • $31,500 for single taxpayers
  • $47,250 for heads of households
  • $63,000 for married persons filing jointly

ABLE account contributions can now qualify for the credit.

2018 529 Plans and ABLE Accounts

Distributions from 529 plans to pay tuition in primary and secondary school up to $10,000 is not a taxable distribution. Distributions from 529 plans can be rolled over tax free to ABLE accounts (up to annual contribution limits). Also, annual contributions to ABLE accounts can be increased under certain circumstances.

2018 Health Savings Accounts (HSA)

The definition of a high-deductible health plan, which is a prerequisite to funding an HSA, means a policy with a minimum deductible for 2018 of $1,350 for self-only coverage and a maximum out-of-pocket cap on co-payments and other amounts of $6,650.These limits are doubled for family coverage ($2,700/$13,300).

The contribution limit for 2018 is $3,450 for self-only coverage and $6,900 for family coverage.

2018 Tax-Free Exchanges (Section 1031)

Under the Tax Cuts and Jobs Act, only exchanges of real property held for business and investment property completed in 2018 and beyond are eligible for like-kind treatment. Gain is taxed to extent of "boot" received. Exchanges of personal property in 2018 and beyond, such as trading in a vehicle used for business, are no longer eligible for like-kind treatment.

Transition Rule:

The new law allows like-kind treatment for exchanges of personal property begun but not completed by the end of 2017, assuming the exchange qualified under the prior law rules for personal property; the 45-day identification deadline and 180-day completion deadline must be met.

Related Parties:

If you make a qualifying like-kind exchange with certain related parties, tax-free treatment may be lost unless both parties keep the exchanged property for at least two years.

What is "like-kind' property?

Like-kind property refers to the nature or character of the property. For example, real estate traded for real estate, land for a building, farm land for city lots, commercial property for residential rental property or a leasehold interest of 30 years or more for an outright ownership in realty.

Real property in the U.S. and foreign real property are NOT (by nature) like-kind.

2018 Individual Health Care Mandate

For 2018 you are required to have minimum essential health coverage through:

  • an employer plan
  • a government program, or
  • other plan

Penalty:

This mandate still applies for 2018, but does NOT apply After 2018. Therefore, if you didn't have minimum essential health coverage for 2018, you will pay a penalty, unless you are exempt from this requirement.

The penalty amount for 2018 is the higher of:

  1. 2.5% of household income above your filing threshold, or
  2. $695 per person in your household ($347.50 per dependent child under age 18),

up to a maximum of $2,085.

Premium Tax Credit: (PTC):

If you bought health care coverage in 2018 through a government exchange (also called "The Health Insurance Marketplace") and your household income is between 100% and 400% of the federal poverty line), there is a PTC available to help pay the premiums for coverage obtained through a government exchange.

You can choose to either have your PTC payments go directly to the insurer on a monthly basis (this the Advance Premium Tax Credit or APTC), or, if you don't want advance payments, claim the PTC on your tax return. Since this is a refundable credit, you will receive a refund even if you owe no tax. But, you must complete Form 8962 and attach it to your return to get this credit.

If you choose to have your PTC paid monthly to the insurance company, this is referred to as an Advance Premium Tax Credit (APTC). Form 8962 is used to reconcile the amount of APTC payments that you should have received vs what you actually did receive during the year.

If your allowable credit on Form 8962 exceeds the advance payments, the excess, called the "Net Premium Tax Credit", can be claimed as a refundable credit on Line 70 of Schedule 5 (Form 1040).

You must complete Form 8962 attach it to your individual income tax return to get a refund.

If you must pay back any excess credit, the repayment is an additional tax that must be reported on Line 46 of Schedule 2 (Form 1040). There is a limit on the required repayment.

Form 1095-A:

You'll receive Form 1095-A if you received health coverage through The Health Insurance Marketplace. Do NOT file Form 1095-A with your income tax return. Keep it for your records. Form 1095-A provides a month-by-month breakdown of the coverage premiums for you and your family and shows the advance payments your received.

The Form 1095-A gives you the monthly premiums for the second lowest cost silver plan (SLCSP) for your family in local area. The SLCSP is referred to as the "reference" or "Benchmark" plan and the SLCSP premium is used th calculate the monthly advance payments as well as the allowable credit on Form 8962.

Health Coverage Tax Credit (HCTC) and the Trade Adjustment Assistance (TAA):

If you do not claim the premium tax credit and qualify for Trade Adjustment Assistance (TAA), you may qualify for the HCTC of 72.5% of the premiums on Form 8885. The Health Coverage Tax Credit provides health insurance premium assistance to individuals to cover them, their spouse and qualifying family members. Advance monthly payments of this credit are available.

Eligible individuals are:

  • Displaced workers who have lost jobs due to foreign competition and are receiving Trade Adjustment Assistance (TAA) benefits
  • Older workers receiving wage subsidies under an alternative trade adjustment assistance (TAA) program or re-employment trade adjustment assistance (RTAA) program established by the Department of Labor, and
  • Pension Benefit Guaranty Corporation (PBGC) pension beneficiaries age 55 to 65 who are not enrolled in Medicare.

The HCTC may not be claimed for any month you were enrolled in Medicare (Part A, B, or C), Medicaid, CHIP, FEHBP, or TRICARE and coverage for family members does not qualify if they are enrolled in such plans. However, once you enroll in Medicare, the HCTC generally can be claimed for eligible coverage of your qualified family members for 24 months.

2018 Self-employment Tax and Deduction for Portion of Self-employment tax

  • One half of the self-employments tax may be claimed as an above-the-line deduction on Schedule 1 of Form 1040.
  • On Schedule SE for 2018, self-employment tax of 15.3% applies to earnings of up to $128,400 after the earnings are reduced by 7.65%.
  • The 15.3% rate equals 12.4% for Social Security (6.2% employee share and 6.2% employer share) plus 2.9% for Medicare (1.45% employee share and 1.45% employer share).
  • There is no cap on earnings for the 2.9% Medicare rate. The 2.9% rate applies to total earnings, from the first dollar and on up.

2018 Social Security Wage Base

  • For 2018, the maximum wage base for Social Security withholdings is $128,400.
  • The employee's share of the Social Security tax rate is 6.2% (50% x 12.4%), therefore, Social Security tax withholdings should not exceed $7,960.80 (6.2% x $128,400).
  • The employee's share of the Medicare tax rate of 1.45% (50% x 2.9%) is withheld from all wages, regardless of amount.
  • The employer also pays 1.45% of each employee's total gross wages.

2018 IRA and Roth IRA Contribution Phaseout; Rollover Limits

For 2018, the contribution limit for traditional IRAs and Roth IRAs is unchanged at $5,500, or $6,500 for those age 50 or older.

You can make only one IRA rollover (60-day rollover) every 12 months. However, there is no restriction on the number of direct transfers you can make each year. If you miss the 60-day deadline because of an event specified in Revenue Procedure 2016-47, you can complete the rollover by self-certifying your eligibility for this relief.

Traditional IRA Deduction Limit for Contributions:

The deduction limit for 2018 contributions to a traditional IRA is phased out for active plan participants with modified adjusted gross income (MAGI) between:

    • $63,000 and $73,000 for a single person or head of household,
    • or between $101,000 and $121.000 for married persons filing jointly and qualifying widows and widowers.

The phaseout range is MAGI between $189,000 - $199,000 for a spouse who is not an active plan participant and who files jointly with a spouse who is an active plan participant.

Roth IRA Contribution Limit:

The 2018 Roth IRA contribution limit is phased out for a single person or head of household with MAGI between $120,000 and $135,000 and for married persons filing jointly and qualifying widows and widowers with MAGI between $189,000 and $199,000.

If you converted your traditional IRA to a Roth IRA in 2018, you cannot undo it; the conversion is permanent.

2018 Deduction Limits for Long-Term Care Premiums

The maximum amount of age-based long-term care premiums that can be included as deductible medical expenses for 2018 (subject to the 7.5%.

  • $1,560 for those age 51 through 60
  • $4,160 for those age 61 through 70
  • $5,200 for those over age 70

Casualty and theft losses

For 2018, only casualty and theft losses of personal-use property in a federally declared disaster are deductible. The $100 and 10%-of-AGI limits continue to apply.

Kiddie Tax

Children with unearned income above $2,100 pay tax on it using the tax rates applicable to trusts and estates. The tax on this unearned income is no longer figured using the top rates of the parents.

The Kiddie Tax computation is generally made on Form 8615 and is attached to the child's return. However, if your child is under age 19 or a full-time student under age 24 and his or her only income is interest and dividends, and other tests are met, you may elect on Form 8814 to include your child's unearned income on your own tax return, instead of computing the kiddie tax on Form 8615.

2018 Annual Gift Tax Exclusion and Gift Tax and Estate Tax Exemption

  • For 2018, the annual gift tax exclusion increases to $15,000 per donee for gifts of cash or present interests.
  • The basic exemption amount for 2018 gift tax and estate tax purposes is increased to $11,180,000 (prior year $5,490,00).
