Tax Credit

A dollar-for-dollar reduction in taxes owed.
A tax credit reduces your tax liability dollar-for-dollar, making it dramatically more valuable than a deduction of the same dollar amount (a deduction only saves you the credit amount × your marginal rate). Credits fall into three categories: (1) nonrefundable — reduce tax owed to zero but no further, with any excess generally not refunded (e.g., the basic Child and Dependent Care Credit, Foreign Tax Credit, most General Business Credits); (2) refundable — paid out as a refund even if they exceed tax owed (e.g., Earned Income Tax Credit, Additional Child Tax Credit, premium tax credit); and (3) partially refundable. Common small-business credits flow through the General Business Credit on Form 3800 and include the Research and Development Credit (Form 6765), Work Opportunity Tax Credit (Form 5884) for hiring from targeted groups, Small Employer Health Insurance Credit (Form 8941) for businesses under 25 employees offering SHOP-marketplace coverage, Disabled Access Credit (Form 8826), Employer-Provided Childcare Credit, and the new Energy-Efficient Commercial Buildings (179D) and Inflation Reduction Act clean-energy credits. Unused General Business Credits generally carry back one year and forward 20. See IRS Publication 334 and Form 3800 instructions for current credits and limitations.
Formula
Tax Savings from Credit = Credit Amount × 1 (i.e., dollar-for-dollar). Tax Savings from Deduction = Deduction Amount × Marginal Tax Rate. A $10,000 credit is worth more than a $40,000 deduction at the 24% rate.Example
A small architecture firm with $80,000 in tax liability claims a $20,000 R&D Credit (Form 6765) for software development costs and a $5,000 Work Opportunity Credit (Form 5884) for hiring two veterans. Combined credits = $25,000, reducing tax owed from $80,000 to $55,000 — a direct dollar-for-dollar reduction. By contrast, a $25,000 deduction at the firm's 24% marginal rate would only save $6,000 in tax. Even better, if the WOTC alone produced a credit larger than tax owed (impossible here but possible for low-tax-year claims), the excess carries forward 20 years.
Why It Matters for Your Business
Tax credits are the single most powerful tax-savings tool because they reduce your bill dollar-for-dollar, not just dollar-times-rate as deductions do, yet small businesses routinely overlook the R&D, WOTC, and Section 45F childcare credits worth tens of thousands annually.
Practical Tips
- •Run a credit study every year — many small businesses qualify for the R&D Credit (software development, process improvement, product design) without realizing the work qualifies
- •File Form 5884 (WOTC) certification within 28 days of a new hire from a targeted group — missed deadlines forfeit the credit entirely
- •Track all eligible expenses contemporaneously — R&D credit claims often fail in audit because of weak time-tracking and documentation of qualified research activities (QRAs)
- •Refundable credits are gold for low-income or net-operating-loss years — they generate cash refunds even when there is no tax liability to offset
Common Questions About Tax Credit
How is tax credit calculated?
The formula is: Tax Savings from Credit = Credit Amount × 1 (i.e., dollar-for-dollar). Tax Savings from Deduction = Deduction Amount × Marginal Tax Rate. A $10,000 credit is worth more than a $40,000 deduction at the 24% rate.. See the worked example below for a step-by-step calculation using realistic numbers.
