Which returns will you file?
Pick the closest fit to see your federal return, your Colorado return, and the other Colorado filing that usually comes with it.
Federal return, IRS
Form 1040
Your annual federal return, with wages, retirement income and investments.
Colorado return, CDOR
DR 0104, 0104EZ or 0104PN
DR 0104 for full-year residents, or the shorter DR 0104EZ if you qualify. Part-year residents and nonresidents add DR 0104PN.
Also watch
Pay 90% by April 15
The filing extension to October 15 is automatic, but at least 90% of the tax must be paid by April 15 to avoid penalties.
Federal return, IRS
Form 1040 with Schedules C and SE
Business profit and self-employment tax on your personal return.
Colorado return, CDOR
DR 0104 or 0104PN
Business income goes on your individual Colorado return. A sole proprietorship has no separate Colorado entity return.
Also watch
Estimated payments
Colorado expects estimated payments on DR 0104EP when next year's tax after credits will be more than $1,000.
Federal return, IRS
Owner's Form 1040
Disregarded by default, unless the LLC elects to be taxed as a corporation.
Colorado return, CDOR
Owner's DR 0104
Colorado treats LLC income the same way as your federal return, so a disregarded single-member LLC's income goes on the owner's return.
Also watch
Periodic report
LLCs file a periodic report with the Colorado Secretary of State every year, online, for a $25 fee.
Federal return, IRS
Form 1065 or 1120-S
An entity return, with a K-1 for each owner.
Colorado return, CDOR
DR 0106
Due April 15 for calendar-year filers. Without the SALT parity election, a composite return is filed for most nonresident owners.
Also watch
SALT parity election
Both entity types can elect to pay tax at the entity level at 4.4%, on DR 0106 or DR 1705. The 2025 election is irrevocable.
Federal return, IRS
Form 1120
The corporate income tax return.
Colorado return, CDOR
DR 0112
Taxed at 4.4%, apportioned by a single receipts factor. Due May 15 for calendar-year filers, with a filing extension to November 15.
Also watch
Estimates and periodic report
Quarterly estimates when next year's tax after credits will exceed $5,000, plus a $25 periodic report with the Secretary of State.
These are typical paths, not a filing determination. Elections, ownership, residency and where you earn income can change what you file; your consultation confirms it.
Filing in Colorado: what's different
The rules that most often change a Colorado return, checked against Colorado Department of Revenue (CDOR) guidance on 27 October 2026.
One flat rate of 4.4%
Colorado taxes individual income at a flat 4.4% of Colorado taxable income, which starts from federal taxable income. No temporary rate reduction applies for 2025.
The same 4.4% rate applies to C corporations and to partnerships and S corporations that make the SALT parity election.
Which Colorado return?
- DR 0104
- Full-year residents, and the base return for part-year residents and nonresidents.
- DR 0104EZ
- A shorter form for full-year residents with no Colorado additions, subtractions or credits.
- DR 0104PN
- Filed with DR 0104 by part-year residents and nonresidents with Colorado-source income.
DR 0104PN prorates the tax so it applies only to income received in Colorado or from Colorado sources.
Key dates for calendar-year filers
Apr 15
Individuals file DR 0104 and pay at least 90% of the tax. Partnerships and S corporations file DR 0106, including any composite return, and pay any tax owed.
May 15
C corporations file DR 0112 and pay their Colorado income tax.
Oct 15
Extended individual returns and extended DR 0106 returns are due. The extension is automatic; no form is needed.
Nov 15
Extended C corporation returns on DR 0112 are due.
A date that falls on a weekend or legal holiday moves to the next business day. Every extension is automatic and covers filing only; tax is due by the original date.
Starts from federal taxable income
DR 0104 begins with federal taxable income from Form 1040 line 15, so your Colorado figures depend on your federal ones. Above $300,000 of federal AGI, part of the federal deduction is added back.
Periodic report
LLCs and corporations file a periodic report with the Colorado Secretary of State every year, online only. The fee is $25, and it can be filed up to two months before or after the report month without penalty.
Sales tax
The state rate is 2.9%, and local taxes are added. Some home-rule cities run their own sales tax under their own rules. If you sell taxable goods, we confirm your state and local registrations during scoping.

Accounts or assets outside the US?
US taxpayers with foreign bank accounts, investments or non-US funds can have three separate reporting duties: the FBAR, Form 8938 and Form 8621 for PFICs. Each has its own rules, and filing one doesn't satisfy another.

A PFIC is a foreign corporation with at least 75% passive income or at least 50% passive assets. Many mutual funds and ETFs registered outside the US, including Indian mutual funds, can qualify, so we check each holding. Form 8938 thresholds are higher if you live abroad.

Questions about filing in Colorado
Something specific to your situation? Ask a US CPA in a 30-minute consultation.
Can Savetaxs prepare both my federal and Colorado returns?
Yes. We prepare federal returns for individuals and businesses together with the matching Colorado returns: DR 0104, 0104EZ or 0104PN for individuals, and DR 0106 or DR 0112, including composite returns and the SALT parity election, for businesses. Your consultation confirms which returns apply to you.
The work is done online, by video or phone, with documents shared through an encrypted upload.
Do I need to request an extension for my Colorado individual return?
No. The Colorado Department of Revenue grants an automatic six-month extension to October 15, with no form to file. It extends the time to file, not to pay. At least 90% of the tax must be paid by April 15 to avoid penalties, and any remaining balance accrues interest. Payments can be made through Revenue Online or with the extension payment form, DR 0158-I.
I moved to or from Colorado this year. Which form do I file?
Part-year residents file DR 0104 with DR 0104PN, which prorates the tax to income received while living in Colorado or from Colorado sources. Nonresidents with Colorado-source income file the same pair. Other states may need their own returns, and we map each one during scoping.
Does my single-member LLC file its own Colorado income tax return?
No, not if it is disregarded for federal purposes. The Colorado Department of Revenue treats LLC income the same way as your federal return, so the income goes on the owner's DR 0104. The LLC still files a periodic report with the Colorado Secretary of State every year, with a $25 fee.
What is Colorado's SALT parity election?
A partnership or S corporation can elect each year to pay Colorado income tax at the entity level, at 4.4%, instead of passing the tax through to its owners. The election is made on the DR 0106, on DR 1705, or with an estimated payment on DR 0106EP, and it binds the entity and all owners. For 2025 it is irrevocable.
An electing entity makes quarterly estimated payments when its tax from the election exceeds $5,000. Whether it helps depends on the owners' federal position, which we review during scoping.
How is pricing determined?
A consultation with a US CPA starts at $59. Filing is priced per return, based on forms and schedules, the number of states, your entity type and the condition of your records. Bookkeeping is priced on monthly volume. You see the fee before you proceed.
I have bank accounts or mutual funds outside the US. What do I need to file?
Possibly one or more of three forms. The FBAR (FinCEN Form 114) applies when your foreign financial accounts total more than $10,000 at any time in the year, and it is filed with FinCEN, not with your tax return. Form 8938 has higher thresholds and is attached to your income tax return. Filing one does not replace the other.
If you own shares in a non-US mutual fund or other passive foreign investment company (PFIC), Form 8621 may also be required for each fund. See our foreign asset reporting service.
