The short answer

A federal income tax deduction lowers the income used to calculate your tax. A tax credit lowers the calculated tax directly. The value of a deduction depends in part on your tax rate. The value of a credit depends on how much you qualify for and how much you can use.

When you budget for a business expense like employee health coverage, you may hear it described as a tax deduction or a tax credit. Both can reduce your tax bill. To estimate the savings, start by identifying which part of the calculation changes.

How a tax deduction works

A deduction reduces taxable income. If an additional $2,000 deduction reduces income that would all be taxed at 24%, it saves $480 in federal income tax. If the deduction spans more than one tax bracket, the savings reflect the rates that apply to those portions of income.

On an individual return, the standard deduction is a set amount based primarily on filing status. Itemizing means adding up eligible expenses such as qualifying charitable gifts. You generally use one of these methods, and some deductions have separate rules that let you claim them even if you take the standard deduction.

How a tax credit works

You apply a credit after calculating the tax it can offset. If you have $3,000 of federal income tax before credits and can use a $2,000 credit in full, the remaining tax is $1,000.

Refundability matters when a credit exceeds the tax it can offset. Suppose you have $700 in tax and qualify for a $1,000 credit. A nonrefundable credit could reduce that tax to zero. With a fully refundable credit, the remaining $300 could be paid to you as a refund. Some credits are partly refundable or have separate rules for unused amounts. Your final refund or balance due also accounts for payments such as withholding and estimated taxes.

Compare a $2,000 credit and a $2,000 deduction

Assume each option is available in full and the entire deduction offsets income taxed at 24%. These amounts illustrate two separate scenarios.

How this can affect your employee health benefits budget

Eligible small employers may qualify for the Small Business Health Care Tax Credit on a portion of the premiums they pay for employee coverage. Eligibility depends on factors such as the number of full-time equivalent employees, average wages, the employer’s premium contribution, and how the coverage was purchased.

If your business claims the credit, reduce the otherwise deductible premium expense by the amount of the credit. For example, if your business paid $18,000 in otherwise deductible premiums and qualifies for a $4,000 credit based on those premiums, the remaining premium deduction would be $14,000. The credit reduces tax by up to the amount you can use. The deduction reduces the income used to calculate tax.

When comparing plans, start with what the business will pay toward premiums. Then ask your tax preparer to estimate the tax effect based on your business structure, payroll records, and eligibility. For help estimating the cost of coverage itself, see our group health insurance budgeting guide.
