The Internal Revenue Service recently issued guidance for taxpayers with certain deductible expenses to reflect changes resulting from the Tax Cuts and Jobs Act also known as the TCJA.

Revenue Procedure 2019-46 (PDF), posted on, updates the rules for using the optional standard mileage rates in computing the deductible costs of operating an automobile for business, charitable, medical or moving expense purposes, according to an IRS news release.

More Info

The guidance also provides rules to substantiate the amount of an employee’s ordinary and necessary travel expenses reimbursed by an employer using the optional standard mileage rates. Taxpayers are not required to use a method described in this revenue procedure and may instead substantiate actual allowable expenses provided they maintain adequate records.

The TCJA suspended the miscellaneous itemized deduction for most employees with unreimbursed business expenses, including the costs of operating an automobile for business purposes. However, self-employed individuals and certain employees, such as Armed Forces reservists, qualifying state or local government officials, educators and performing artists, may continue to deduct unreimbursed business expenses during the suspension, the news release continued.

Moving Expenses

The TCJA also suspended the deduction for moving expenses. However, this suspension does not apply to a member of the Armed Forces on active duty who moves pursuant to a military order and incident to a permanent change of station, the IRS release added.

Private Collection Agency

Taxpayers who are contacted by a private collection agency on behalf of the IRS might have questions about the program. These taxpayers can visit to find answers to questions they might have.

In fact, to better help these taxpayers, the IRS recently updated the private debt collection pages on These updates added more information for taxpayers whose case is being handled by a collection agency.

The web pages include info such as:

  • The names and addresses of the collection agencies.
  • How the process works.
  • What a taxpayer should do after being contacted.

Here are some things taxpayers should know about the private debt collection program:

  • Before being contacted by a private collection agency, the taxpayer will receive two letters.
    1. Notice CP40 comes from the IRS to individual taxpayers. Business taxpayers receive a Notice CP140 from the IRS. These letters tell the taxpayer their overdue account was assigned to a private collection agency.
    2. An initial contact letter comes from the private collection agency. This letter has info on how the taxpayer can resolve their overdue taxes.
  • Both letters contain a taxpayer authentication number. It’s used by the collection agency to confirm the taxpayer’s identity. It’s also used by the taxpayer to verify the caller is from a legitimate collection agency.
  • Taxpayers whose debt was transferred to a private collection agency will be contacted by one of four agencies. When contacted, the taxpayer should make sure the caller is from one of the private collection agencies listed on
  • The private collection agency will ask the taxpayer a series of questions to make sure they’re talking to the correct person.
  • The taxpayer will be asked to exchange portions of the taxpayer authentication number with the private collection agency. This allows the caller and the taxpayer to validate each other’s identity.
