State Tax Update: PA Department of Revenue Raises Burden of Proof for Expense Deductions

PA Department of Revenue more info required to support business expense tax deductions Pennsylvania Department of Revenue (DOR) Secretary Eileen McNulty confirmed earlier this month in a letter to state legislative leaders that the DOR has formalized into policy its supporting documentation requirements for all business expenses claimed on personal income tax returns.

Business Expenses in Pennsylvania

Examples of unreimbursed business expenses that can be deducted on Pennsylvania state income tax include:

  • Work clothes
  • Small tools and supplies
  • Travel and mileage
  • Meals
  • Educational expenses
  • Moving expenses into PA

DOR Increasing Scrutiny

The policy announcement is the latest chapter in ongoing efforts by the DOR to increase scrutiny and documentation of unreimbursed business expense deductions. Additionally, Secretary McNulty announced in her letter that the DOR would broaden its review of such deductions to include examination of PA-40 Schedule C expenses (profit or loss from business or profession).

DOR’s actions over the past year regarding these deductions have caused consternation and headaches for practitioners and taxpayers alike. So what does this mean for your state tax filings?

New Methods to Justify Deductions

Under this new policy, the DOR will accept one of three forms of documentation to demonstrate that a taxpayer’s employer requires unreimbursed business expenses. One of the below items must be submitted with the originally filed tax return to support these deductions:

  1. A letter from the employer
  2. A copy of the employer’s employee expense reimbursement policy
  3. A signed (and notarized) affidavit

More Supporting Documentation May Be Required

In addition to the above forms, however, the DOR also indicated that it might request additional information to justify expenses the department believes may have been erroneously reported or not sufficiently substantiated.

Due to this higher level of scrutiny and review these deductions now trigger, RKL recommends that taxpayers submitting these expenses be hyper-vigilant when it comes to retaining documentation. Taxpayers will benefit from erring on the side of over retention of receipts, paperwork, emails, and any other proof of authorization or accumulation of expenses.
