Working from home has become commonplace. But just because you
have a home office space doesn’t mean you can deduct expenses associated with
it. And for 2018, even fewer taxpayers will be eligible for a home office
deduction.
Changes under the TCJA
For employees, home office expenses are a miscellaneous itemized
deduction. For 2017, this means you’ll enjoy a tax benefit only if these
expenses plus your other miscellaneous itemized expenses (such as unreimbursed
work-related travel, certain professional fees and investment expenses) exceed
2% of your adjusted gross income.
For 2018 through 2025, this means that, if you’re an employee,
you won’t be able to deduct any
home office expenses. Why? The Tax Cuts and Jobs Act (TCJA) suspends
miscellaneous itemized deductions subject to the 2% floor for this period.
If, however, you’re self-employed, you can deduct eligible home
office expenses against your self-employment income. Therefore, the deduction
will still be available to you for 2018 through 2025.
Other eligibility requirements
If you’re an employee, your use of your home office must be for
your employer’s convenience, not just your own. If you’re self-employed,
generally your home office must be your principal place of business, though
there are exceptions.
Whether you’re an employee or self-employed, the space must be
used regularly (not just occasionally) and exclusively
for business purposes. If, for example, your home office is also a guest
bedroom or your children do their homework there, you can’t deduct the expenses
associated with that space.
2 deduction options
If you’re eligible, the home office deduction can be a valuable
tax break. You have two options for the deduction:
- Deduct a portion of your mortgage interest, property
taxes, insurance, utilities and certain other expenses, as well as the
depreciation allocable to the office space. This requires calculating,
allocating and substantiating actual expenses.
- Take the “safe harbor” deduction. Only one simple
calculation is necessary: $5 × the number of square feet of the office
space. The safe harbor deduction is capped at $1,500 per year, based on a
maximum of 300 square feet.

2017 return or would like to know if there’s anything additional you need to do
