Significant U.S. Tax Changes for 2017

(2018 Filing Season)

Tax Cuts and Jobs Act - (2018 Changes)

The Tax Cuts and Jobs Act was signed by President Trump on December 22, 2017, and includes significant changes to personal and business taxation.  Most of the provisions of the new Act take effect for 2018, and a summary can be viewed here.

This page deals with tax changes which will be in effect for 2017, since tax returns prepared during the spring of 2018 will still follow the former code.  We will continue to update information regarding the effect of the Tax Cuts and Jobs Act as new information becomes available.

Individual Taxpayer Identification Number (ITIN) Renewal

Individual Taxpayer Identification Numbers obtained prior to January 1, 2013 and not used on three consecutive tax year's returns will need to be renewed.

Affordable Care Act

Under the Affordable Care Act, the federal government, state governments, insurers, employers, and individuals are given shared responsibility to reform and improve the availability, quality, and affordability of health insurance coverage in the United States. Starting in 2014, the individual shared responsibility provision calls for each individual to have minimum essential health coverage (known as minimum essential coverage) for each month, or qualify for an exemption. Otherwise, they are required to make a payment when filing their federal income tax return.

The provision applies to individuals of all ages, including children. The adult or married couple who can claim a child or another individual as a dependent for federal income tax purposes is responsible for making the payment if the dependent does not have coverage or an exemption.

The provision went into effect on Jan. 1, 2014. It applies to each month in the calendar year. The amount of any payment owed takes into account the number of months in a given year an individual is without coverage or an exemption.

For 2016 & 2017 the penalty for not having health coverage has increased to the higher of $695 per adult and $347.50 per child under 18 (maximum $2,085) or 2.5% of household income to a maxumum of the national average for Bronze plan coverage.  The annual national average premium for a bronze level health plan available through the Marketplace is $2,676 per year ($223 per month) for an individual and $13,380 per year ($1,115 per month) for a family with five or more members.

General Tax Provisions:

Income tax returns are due this year on April 17, 2018 unless an extension is filed and taxes are paid by that date.  Please contact us if you believe that you will need an extension for filing 2017 taxes.

Increased Scrutiny

Again this year, Internal Revenue Service has increased its scrutiny of returns filed, to ensure that fraudulent claims and false deductions are less likely to be missed.  The following areas on a return are likely to increase audit scrutiny:

  1. Amount of earnings - Normally about 1% of returns are audited but if income is over $200,000 have a 3.7% chance of audit, while income over $1,000,000 increases the likelihood of audit to 12.5%;
  2. IRS have increased matching of 1099 and W2 information to returns, and are likely to issue an audit letter if it appears that an item of income has been missed;
  3. Large charitable donations or itemized deductions increase the likelihood of audit;  It is important to maintain adequate records to support all deductions;
  4. Real estate losses, and "real estate professionals" have been targeted for additional scrutiny;
  5. Business meals, travel and entertainment are a favorite target of IRS audits;
  6. Claiming too high a vehicle business use percentage can lead to an audit;
  7. Filing a business statement showing a large loss consistently, is likely to cause IRS to challenge the business as a "hobby" where losses are not deductible;
  8. Cash businesses continue to be a favorite audit target;
  9. Any Taxpayer with foreign bank or financial assets is an increased target.  IRS has recently been very successful in levying penalties for late, absent, or inadequate reporting of foreign assets and income.
  10. IRS has been directed to look more closely at any situation where a Taxpayer has foreign currency transactions in excess of $10,000 reported by banks.

As a result of the likelihood for increased government scrutiny of all returns filed, we have this year implemented our "Prepaid Audit Assurance Program".  Under this Program, we cover the costs of representation in the event you are audited.
