Colorado Qualified Business Income Deduction Addback Explained

The Colorado Qualified Business Income (QBI) deduction addback reverses the benefit of the federal QBI deduction on a taxpayer’s state tax return. This adjustment increases your Colorado taxable income, making it higher than what is calculated on your federal return. This ensures that federally deductible income is included in the base for calculating Colorado income tax.

Understanding the Federal Qualified Business Income Deduction

The federal Qualified Business Income (QBI) deduction, established under Section 199A of the Internal Revenue Code, allows owners of certain pass-through businesses to deduct up to 20% of their qualified business income. Pass-through entities include sole proprietorships, partnerships, S corporations, and some trusts and estates.

Qualified business income is generally the net profit from a qualified trade or business. Certain types of income are specifically excluded, such as investment income, capital gains, dividends, and interest income that is not directly related to the business’s primary activities. The deduction is taken on the individual owner’s personal tax return, reducing their overall federal taxable income.

The calculation of the QBI deduction can be complex, with limitations based on the taxpayer’s taxable income, the type of business, W-2 wages paid, and the unadjusted basis of qualified property. For many small business owners, it represents a significant federal tax savings.

The Colorado Addback Requirement

Colorado law requires an addback of the QBI deduction claimed on a federal return, which negates the tax benefit for state income tax purposes. The state’s rationale for this is to maintain its tax base by not conforming to this part of the federal tax code for higher-income taxpayers.

This addback requirement is not universal and applies only when a taxpayer’s adjusted gross income (AGI) exceeds certain thresholds. The addback is required for single filers with an AGI over $500,000 and for joint filers with an AGI over $1,000,000. However, taxpayers who file a Schedule F (Profit or Loss from Farming) with their federal return are exempt from the addback requirement, regardless of their income level.

Calculating and Reporting the Addback

The total QBI deduction amount claimed on your federal Form 1040 is the figure needed for the addback. This amount is reported as an addition to federal taxable income on the Colorado Individual Income Tax Return (Form DR 0104).

You must enter the addback amount on the specific line designated for this adjustment. This entry increases the federal taxable income that is the starting point for the state tax calculation, thereby establishing your Colorado taxable income.

Interaction with the SALT Parity Act Election

The QBI addback also interacts with Colorado’s SALT Parity Act election. This act allows certain pass-through entities, such as partnerships and S corporations, to elect to pay state income tax at the entity level, rather than the tax being paid by the individual owners on their personal returns. This election is a response to the federal limitation on the state and local tax (SALT) deduction for individuals.

If a pass-through entity makes the SALT Parity Act election, its partners or shareholders are required to add back the entire amount of their federal QBI deduction on their Colorado return. This requirement applies regardless of the individual’s adjusted gross income. Making this election makes the addback mandatory for a taxpayer who would have otherwise been exempt based on the AGI thresholds.
