Income Taxes

Most people do not find themselves staying up late at night reading the tax code with the eagerness that they would show for the latest page-turner. But if you develop a basic familiarity with business income tax rules, you just may find it interesting to see how you can manage your business with an eye toward minimizing taxes.

In general, you will find that the IRS gives a wide range of expenses that it allows as deductible. The term "ordinary and necessary" is operative here. If a deduction is "ordinary," or common to your industry, the odds are good that it will be allowed. The way your business is taxed will depend on the form of business you have selected.

The type of tax treatment and form you file will depend on the form of business entity that you have selected. This chart gives a quick overview.

Proprietorship

Business does not pay the tax

Form 1040, Schedule C

Partnership

Business does not pay the tax

Form 1065

C Corporation

Corporation files return

Form 1120 or 1120-A

S Corporation

Business does not pay tax

Form 11-20 S

LLC

May file as sole practitioner (Form 1040, Schedule C), corporation (Form 1120 or 1120-A ) or partnership (Form 1065)

As indicated on the chart above, a proprietorship, partnership, S corporation and possibly an LLC will not pay taxes itself. The tax burden is passed along to the business owner, and the income is taxed at the individual's personal tax rate.

A corporation, which is treated as a separate entity or "person," pays taxes at a graduated rate. Currently, the first $50,000 of net income is taxed at a 15 percent rate. The next $25,000 of income is taxed at 25 percent. Rates for net income over $75,000 vary between 34 percent and 39 percent.

What about business tax deductions?

You can be fairly certain that just about any expense incurred to benefit your business will be deductible for tax purposes. Remember the "ordinary and necessary" guideline.

The IRS has been specific in its rulings regarding some types of deductions. Depreciation, travel expenses, meals and entertainment and auto expenses fall into that category. If it is ordinary or necessary to your industry, it normally will be deductible.

First, here are just a few deductions your business can take:

  • interest payments
  • rent
  • office supplies
  • fees and commissions
  • insurance
  • expenses for attorneys
  • accounting services and other professional advisors
  • repairs and maintenance of your equipment
  • vehicles the business owns
  • office supplies and expenses

Employee-related expenses can also be deducted, such as:

  • wages
  • payroll taxes
  • benefits and retirement contributions
  • pension and profit-sharing plans

Expenses related to selling your products are allowable deductions:

  • marketing and advertising costs
  • trade publications
  • fees and commissions
  • association memberships
  • business conventions and trade shows

Health, dental and group life insurance are all allowable deductions, as are moving expenses. There are other qualified benefit plans which are deductible for the business. In addition, these benefits are not taxable to employees.

In general, the IRS wants to make sure that the business owner does not set up a business plan that benefits himself or herself more than his or her employees.

What do I need to know about depreciation?

Although depreciation is not a cash expense, it is deducted from income on your taxes and thus reduces your tax liability.

If you buy equipment or machinery that has a useful life of more than 1 year, you will most likely deduct the cost over a number of years. This rule recognizes that you will be using the asset for more than 1 year.

Can I buy a truck for my business and write it off right away?

This is where depreciation kicks in. You will most likely have to depreciate it over a period of years.

How do you figure the amount of depreciation?

There are two types of depreciation: "straight-line" and "accelerated."

Straight-line is the simplest. Divide the cost of the asset by the number of expected years of life.

Accelerated depreciation means that the tax deduction for a purchase is sped up; you are allowed to take a larger amount as a write-off in the first years after you have made the purchase.

So I can deduct the full cost of equipment when I buy it? Are there any exceptions?

The answer is yes. A small business is most likely to qualify. You can choose to deduct up to $100,000 worth of depreciable assets in the year you make the purchase.

Of course there are exceptions. If you buy more than $400,000 of depreciable assets in the year, this rule does not apply; you will need to make adjustments to the $100,000 first year write-off as it phases out.

A second exception is that the amount you deduct cannot be greater than your taxable income for that year.

Can I deduct travel, meals and entertainment?

The IRS wants the business to distinguish between travel for business purposes and personal travel. Deductions for business travel covers almost all expenses you would encounter on a business trip: any form of transportation that takes you to your destination, meals, lodging, cabs or limos from the airport or while in a city, tips, laundry and cleaning expenses.

If a trip is partly business and partly personal, you are allowed to deduct only the business portion.

As for meals and entertainment, the IRS allows a business to deduct only 50 percent of the expense. This applies to you and a guest that you might pay for-you can deduct half of each meal or entertainment.

If you are a sole proprietor paying taxes through your personal Form 1040, you will take the deduction on Schedule C. A corporation may reimburse its employee-owner or employee for 100 percent of the meal and entertainment expenses, but it will still only be able to deduct 50 percent for tax purposes.

Can I deduct my automobile expenses?

There are two ways to compute your automobile expenses.

Each year, the IRS states a per-mile allowance for deductions, and that might be the simplest way to calculate the expense. The alternate method is to keep track of all car-related expenses like gas and oil, tires and repairs and use the actual costs.

Can I deduct all of my automobile expenses?

As with business and personal travel, you will need to allocate expenses if you use your car for both business and personal reasons. Commuting expenses are not deductible, and neither are parking fees at your normal place of work; these are considered personal expenses.

Can I depreciate automobile expenses?

The business entity can depreciate an automobile that it has purchased.

Can I deduct software that comes separate from a computer?

Yes, you can deduct 100 percent of the software cost in the year you make the purchase.
