Eligibility to File Colorado Form 104PN
Colorado Form 104PN is required for part-year residents and nonresidents to determine their Colorado tax liability based on residency status and income sources.
2.1 Who is Required to File as a Part-Year Resident?

Part-year residents must report income earned during their Colorado residency period and apportion their income accordingly. Filing is required if their income meets Colorado’s filing thresholds. The form helps determine the portion of income subject to Colorado state tax based on the duration of residency.
2.2 Who is Required to File as a Nonresident?
Nonresidents must file Colorado Form 104PN if they earned income from Colorado sources, such as wages, self-employment, or other income tied to the state. This form is required to calculate tax liability on income earned within Colorado. Nonresidents do not file a full state return but must report and pay taxes on income derived from Colorado activities. Failure to file may result in penalties. The form ensures accurate reporting of Colorado-sourced income and proper tax calculation for nonresident filers.

Determining Residency Status
Determining residency status is crucial for accurately filing Colorado Form 104PN. It involves assessing domicile and time spent in Colorado to classify as a resident or nonresident.
3.1 Definition of a Colorado Resident
A Colorado resident is defined as an individual who maintains a permanent home in the state and spends a significant portion of the year there. Residency is determined by domicile, which involves intent to remain indefinitely. Factors such as voting registration, driver’s license, and property ownership can support residency claims. For tax purposes, residents are subject to state income tax on all income, regardless of source. Understanding this definition is critical for accurately completing Colorado Form 104PN and ensuring compliance with state tax requirements.
3.2 Factors Determining Part-Year Residency
Part-year residency in Colorado is determined by the duration of stay and domicile within the state during the tax year. Individuals who maintain a permanent home in Colorado but spend part of the year elsewhere qualify. The specific start and end dates of residency are critical for calculating tax liability. Factors such as voting registration, driver’s license, and property ownership can influence residency status. For part-year residents, Form 104PN requires precise start and end dates of Colorado residency to accurately apportion income and determine tax obligations.

Colorado Form 104PN requires accurate residency dates and income apportionment. It includes two columns for federal and Colorado adjusted gross income calculations, ensuring precise tax liability determination;
4.1 Understanding the Structure of the Form
Colorado Form 104PN is divided into two main columns: Column A for federal adjusted gross income and Column B for Colorado-specific adjustments.

To complete Colorado Form 104PN, taxpayers must provide specific information, including residency start and end dates, federal adjusted gross income, and Colorado-specific adjustments.

Calculating Income for Colorado Form 104PN
Colorado Form 104PN requires calculating modified federal and Colorado adjusted gross income. Part-year residents report income as full-year residents initially, then prorate based on residency duration. Accuracy is crucial for correct tax assessment and compliance.

5.1 Modified Federal Adjusted Gross Income (Column A)
Column A of Colorado Form 104PN requires calculating the modified federal adjusted gross income (MAGI). This starts with the federal AGI from the taxpayer’s IRS Form 1040. Colorado-specific modifications are then applied, such as adding back certain deductions or excluding specific income items not taxable in Colorado. Accurate calculation is critical, as this column serves as the foundation for determining taxable income. Taxpayers must ensure all federal adjustments align with Colorado tax laws to avoid errors in their state tax liability calculation.
5.2 Modified Colorado Adjusted Gross Income (Column B)
Column B of Colorado Form 104PN calculates the modified Colorado adjusted gross income. This begins with the federal AGI from IRS Form 1040 but applies Colorado-specific modifications. Taxpayers must add back certain deductions or exclude income items not taxable in Colorado. For example, Colorado does not tax Social Security benefits, so these are excluded. Accurate calculation is essential, as this column determines the taxable income subject to Colorado state tax. Ensure all adjustments align with Colorado tax laws to avoid errors in tax liability calculation.

Tax Proration and Apportionment
Tax proration and apportionment for part-year residents and nonresidents are calculated using Colorado Form 104PN, ensuring income is prorated based on residency period or Colorado-sourced income.
6.1 How Income is Apportioned for Nonresidents
For nonresidents, income is apportioned based on Colorado-sourced income. Using Form 104PN, nonresidents calculate the percentage of income earned in Colorado. This involves separating federal adjusted gross income (Column A) from Colorado-specific adjustments (Column B). The apportionment percentage is applied to total income to determine the taxable amount. Only income earned in Colorado or from Colorado sources is subject to state tax. This ensures nonresidents are taxed fairly based on their economic ties to the state, aligning with Colorado tax regulations.
6.2 Prorating Income for Part-Year Residents
Part-year residents prorate income based on the duration of Colorado residency. Using Form 104PN, they calculate the proration factor by dividing Colorado residency days by 365. This factor applies to total income, ensuring only income earned during residency is taxed. Column A reflects federal adjusted gross income, while Column B adjusts for Colorado-specific deductions. The proration factor is then applied to determine taxable income. This method ensures fairness, taxing only the income earned during the period of Colorado residency, aligning with state tax regulations.
