As a business owner, you may take all legitimate business expenses as tax deductions, to reduce your business tax. But some business tax deductions are easier to figure out than others. 

For example, taking a deduction for the cost of supplies is pretty straightforward, and deducting, and interest on business purchases is pretty easy to calculate. 

Some Tricky Business Tax Expenses to Deduct

But for other business expenses, it's not easy to figure out what's deductible and what's not. Hence, this list of 7 business expenses that you should be cautious about taking. This is not to say that they are not legitimate business expenses, but these expenses are on this list because the deduction might be limited, or an audit trigger, or just complicated to calculate. 

Proving Deductions for Business Expenses

First, a general caveat for business owners: The most common way the IRS gets business taxpayers at audit is for not having the documents to prove deductions. Make sure you have the business records you need. 

Here's the list of business tax deductions to take with caution: 

1. Business Driving Expenses 

Deducting expenses for use of your car or a company car for business driving is both complicated and an audit red flag.

First, to deduct expenses for business use of your car, you must drive at least 50% of the time for business purposes. Then, you MUST be able to show excellent at-the-time records to prove the business purpose for all business driving expenses, whether you take the standard mileage expenses or actual expenses. 

2. Home Business Space Deductions

The IRS looks carefully at attempts to claim a deduction for a home business space. In particular, the IRS wants to be sure this space is being used ONLY for business purposes. Even a once-a-year personal use can negate the deduction. Second, be careful to deduct only the actual amount of space used for the business and make sure you have nothing personal in that space. The IRS can come to your home and check. 

3. Employee Gifts, Bonuses, and Awards

This one sounds like a no-brainer - all types of employee gifts, awards, and bonuses should be deductible to your business - rewarding employees is certainly an allowable business expense. But there are limits on some of these items (gifts, for example, must be small), and you also have to consider that some of these (bonuses, for example) are taxable to the employee. Lots of things to think about before you run out and buy something for employees. 

4. Dues to Clubs and Organizations

Business owners should be able to join clubs to network and for interaction with other businesses in similar professions. But not all club dues are deductible - forget the golf club, for example, even if you do business while you're on the course. Only dues for professional and trade organizations are acceptable. And some club dues and expenses are strictly forbidden, like political organizations. 

5. Business Travel Expenses

Like expenses for business driving, business travel expenses are both limited in amount and restricted. Can you deduct the cost of taking your spouse on a business trip? It depends on several factors. Can you deduct the cost of travel from home? What about travel overseas? Yes, it's complicated. 

6. Meals and Entertainment

As of the 2018 tax year, business entertainment expenses are no longer deductible. That means no sporting events, concerts, or resorts. Meal expenses are still deductible, and you are still limited to 50% of allowable expenses. Entertainment for promotional purposes is still deductible, for example a community event.

7. Depreciation on Business Assets

This is probably the most complicated business tax deduction. The laws keep changing and limits and restrictions on accelerated depreciation change each year. The limits for Section 179 deductions and bonus depreciation have increased. That means you and your tax professional can do some tax planning. But you'll need the help of someone who is familiar with the details of depreciation; it's tricky, believe me. 

8. Donations to Charity

Corporations can deduct donations to charities. For all other business types, charitable donations are deductible through your personal tax return. 

9 . Purchase of a Computer

Computers are legitimate business purchases. Changes to the tax law have loosened the restrictions on computers, tablets, and peripherals (like software and printers). They are no longer listed property, but you must be able to show that you are using them at least 50 percent of the time for business.

Computers, etc. aren't subject to depreciation restrictions, unless they cost more than $2,500. This means you can deduct the full cost of one of these devices in the year your business bought it and began to use it.
