HB26-1222 instructs Colorado to “decouple” from several recent federal changes that expanded business-related tax deductions. For tax years beginning January 1, 2027, individual and corporate taxpayers must add back certain federal deductions (business interest under IRC §163(j), bonus depreciation §168(k), the elective production property depreciation §168(n), and immediate domestic R&D expensing under §174A) to their Colorado taxable income.
The bill then allows taxpayers to subtract those add‑backs over time using specified amortization periods that approximate how the items would have been treated under the prior federal rules.
The revenue produced by these add‑backs is earmarked to fund a new refundable Family Affordability Credit targeted at families with children. Legislative Council staff will annually set the per‑child credit amount so that the total credits available in a year are projected to equal the revenue raised by the add‑backs.
The credit is refundable, subject to income phase‑outs, and designed to preserve the state’s targeted support for low‑ and moderate‑income families while keeping broad federal conformity for other tax calculations.
At a Glance
What It Does
HB26-1222 adds back to Colorado taxable income the incremental federal deductions created by recent federal law changes (IRC §§163(j), 168(k), 168(n), 174A) for tax years beginning January 1, 2027, and permits taxpayers to recover those amounts over multi‑year subtraction schedules starting in 2028. It then converts the resulting state revenue into a refundable Family Affordability Credit whose total annual value is set to match the projected revenue gain.
Who It Affects
Colorado resident individuals with children, pass‑through owners, and corporations that claim the targeted federal deductions—particularly capital‑intensive and manufacturing businesses—plus tax practitioners, the Department of Revenue, and Legislative Council staff who must implement the revenue‑matching mechanism.
Why It Matters
The bill selectively breaks conformity with federal changes to preserve state tax revenue used for an income‑targeted family credit. That shifts the incidence of recent federal incentives: businesses keep the federal benefit for federal tax purposes but face higher Colorado taxable income, increasing state compliance complexity and altering state competitiveness choices.

What This Bill Actually Does
HB26-1222 takes a surgical approach to state tax conformity. Rather than reworking Colorado’s entire income tax base, it asks taxpayers to add back only the incremental amounts created by four specific federal changes: expansion of the business interest limitation (IRC §163(j)), the restoration of 100% bonus depreciation (IRC §168(k)), a new elective 100% depreciation for qualified production property (IRC §168(n)), and a new immediate domestic R&D expensing rule (IRC §174A).
For tax years starting January 1, 2027, both individual and corporate filers must increase their Colorado taxable income by the amount of those federal deductions to the extent they exceed what would have been allowed prior to the federal changes (with narrow reductions allowed where older deduction rules would otherwise apply).
Recognizing that those add‑backs would be lumpy, the bill builds in phased subtractions that allow taxpayers to recoup the disallowed federal deductions on a state return over time. For example, the legislation specifies a five‑year phase for the business interest addback, a ten‑year phase for bonus depreciation, a very long phase (38 years in the text) for qualified production property, and a four‑year phase for R&D expensing.
Subtractions begin in tax years starting January 1, 2028, apply after other subtractions, and may be carried forward up to ten years if a taxpayer’s income is insufficient to absorb them in a given year.The revenue the state collects from those incremental add‑backs is not left in the general fund. Section 3 creates a refundable Family Affordability Credit aimed at the same target population as the existing family affordability tax credit: low‑ and moderate‑income families with children.
Legislative Council staff will calculate, as part of its December revenue forecast each year starting in 2027, the projected net revenue gain from the add‑backs; staff will then set a single dollar amount per child (the same for single and joint filers at the same age category) so total credits claimed are projected to equal the revenue gain. The credit is refundable, subject to phase‑out thresholds tied to adjusted gross income, can be apportioned for part‑year residents, and the Department of Revenue is encouraged to design a monthly refund option.
The Five Things You Need to Know
The bill requires add‑backs to Colorado taxable income for federal deductions under IRC §163(j), §168(k), §168(n), and §174A for tax years beginning January 1, 2027.
Subtractions to recoup the add‑backs begin in tax years starting January 1, 2028, and are amortized as: one‑fifth over 5 years, one‑tenth over 10 years, one‑thirty‑eighth over 38 years, and one‑fourth over 4 years (text assigns these schedules to the four add‑backs).
Legislative Council staff must annually project the net revenue gain from the add‑backs and set a single per‑child dollar amount so that total Family Affordability Credits claimed are projected to equal that revenue gain.
The Family Affordability Credit is refundable, applies in addition to existing child credits, is phased down by adjusted gross income using fixed decrement rates, and can be apportioned for part‑year residents; the Department may offer refunds in 12 monthly installments.
Excess subtractions (if a taxpayer’s deductions exceed Colorado taxable income after other subtractions) may be carried forward up to ten years and must be applied to the earliest eligible year; any remainder at the end of that period is forfeited.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Legislative declaration and purpose
This section explains why the General Assembly is targeting selective federal changes: expanded business deductions reduced Colorado taxable income and, the bill asserts, materially reduced state revenue used to support the family affordability tax credit. The declaration frames the bill as a revenue‑neutral policy that preserves broad federal conformity while reclaiming incremental revenue from those federal changes to fund a targeted family credit. Practically, this is the policy hook the Department and courts will use to interpret implementation choices and to defend the decoupling as limited and intentional.
Individual add‑backs and phased subtractions
Adds specific subsections (3)(v)–(y) requiring resident individuals to add back the amounts of federal deductions attributable to IRC §163(j), §168(k), §168(n), and §174A for tax years beginning Jan 1, 2027, with narrowly tailored exceptions that let taxpayers reduce the addback by amounts they could have claimed under prior IRC sections. It then creates subsection (4)(ff) allowing multi‑year subtractions beginning in 2028 (the 5‑, 10‑, 38‑, and 4‑year schedules). The provision mandates ordering rules (these subtractions apply after other statutory subtractions except one listed exception) and creates a ten‑year carryforward window for unused subtraction amounts, which is material for taxpayers with volatile incomes or large initial addbacks.
Family Affordability Credit mechanics and governance
Creates the new refundable Family Affordability Credit, defines eligible children (aligned to IRC §152(c) but with Colorado age bands), specifies income phase‑outs for single and joint filers, and makes the credit refundable and available in addition to existing child credits. Critically, the statute tasks Legislative Council staff with projecting the revenue gain from the addbacks each December and setting a single dollar amount per young child (and 75% of that amount for older children) so the total credits available are projected to match that revenue. The Department must report revenue gains annually to Legislative Council staff, and the statute expressly allows monthly refunding by rule or program design.
Corporate add‑backs and phased subtractions
Mirrors Section 2 for C‑corporations by adding analogous addback subsections (2)(m)–(p) and the corresponding phased subtractions (3)(u). The corporate language contains the same exceptions allowing reduction of the required addback where alternative depreciation or capitalization rules would have applied under pre‑change federal law, and it preserves the same carryforward and ordering mechanics. Practically, this creates a state‑level distinction between federal and Colorado taxable income for affected corporations and will require adjustments in Colorado apportionment and tax provision workpapers.
Effective date and referendum provision
Sets the act’s effective date tied to final adjournment timing and includes the standard referendum trigger language. The section also contains the General Assembly’s TABOR‑related declaration in the earlier legislative findings: the bill asserts any net district revenue gain is incidental and de minimis, a point that both influences its voter‑approval posture and may be tested if revenue effects diverge from projections.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Low‑ and moderate‑income families with children: The new refundable Family Affordability Credit targets the same population as Colorado’s prior family affordability policy, increasing after‑tax resources for eligible families and offering monthly refund delivery as an option for cash flow.
- Households with young children: The statute sets higher credit amounts for children five and under (full amount) and 75% of that amount for children ages six through sixteen, concentrating benefits where studies suggest impact on poverty reduction is larger.
- Legislative Council and budget planners: The bill gives Legislative Council staff an explicit role in linking revenue projections to credit sizing, helping the legislature operationalize a revenue‑neutral policy in future forecasts and budgets.
Who Bears the Cost
- Capital‑intensive and manufacturing businesses: Firms that rely heavily on bonus depreciation, production property elective depreciation, or immediate R&D expensing will face higher Colorado taxable income relative to federal returns, increasing state tax liabilities and compliance complexity.
- Taxpayers and tax practitioners: The addback/subtraction mechanics, ordering rules, multi‑year amortizations, and ten‑year carryforward create added complexity for returns, bookkeeping, and planning, increasing preparation costs.
- Colorado Department of Revenue and Legislative Council staff: DOR must implement new forms, administer refundable monthly payments, and handle carryforward tracking; Legislative Council must produce reliable revenue‑matching projections each December, adding analytical workload and forecasting risk.
Key Issues
The Core Tension
The central dilemma is balancing two legitimate goals that pull in opposite directions: reclaiming state revenue to preserve targeted family assistance by selectively decoupling from federal business incentives, versus maintaining tax conformity and simplicity for businesses and taxpayers. The bill preserves federal benefits at the federal level but imposes Colorado‑only tax costs and complex amortization rules — a policy that protects low‑income households but increases compliance burdens and may change state competitiveness for capital investment.
The bill is precise in its target but introduces several operational and interpretive trade‑offs. First, tying the Family Affordability Credit’s total annual value to Legislative Council projections creates a revenue‑matching rule that is only as good as the forecast: overestimates leave unspent revenue (or smaller-than‑expected credits), while underestimates could create political pressure to expand the credit or reallocate funds.
Second, the subtraction schedules are uneven and lengthy (notably a 38‑year schedule in the text). Those staggered recoveries create timing mismatches between when Colorado collects revenue from addbacks and when taxpayers economically realize state relief, complicating cash‑flow comparisons and making year‑by‑year revenue neutrality hard to guarantee.
Third, the statutory ordering rules and carryforward ceilings raise administrative questions: how to sequence the new subtractions against existing subtractions and credits, how to allocate addbacks and subtractions among partners or multi‑state entities, and how the monthly refund mechanism will operate for refund‑eligible taxpayers. Finally, the bill contains a possible drafting inconsistency in one cross‑reference to the subsection tied to the 38‑year amortization; that ambiguity will require correction or administrative guidance to avoid disputes over which deduction is subject to which amortization period.
