Tax preparation for Centennial, Colorado

Centennial wraps around the south end of the Denver Tech Center, and the returns reflect that. Corporate compensation, a fair amount of consulting work that started as a layoff, and a housing stock old enough that a lot of it has been converted into rentals rather than sold.

Equity compensation from a DTC employer

RSUs, ISOs, and ESPP shares create two taxable events that people routinely collapse into one: the vest or exercise, and the later sale. The trap is basis. Brokers frequently report only what you paid out of pocket and omit the compensation income already taxed through your W-2, which makes the sale look far more profitable than it was and produces a return that overstates gain. It is one of the most common overpayments we find, and correcting it takes nothing more exotic than checking the 1099-B against your vest or exercise records. If you have exercised ISOs and held them, alternative minimum tax enters the picture as well.

Rentals, including the accidental kind

A house that got rented out instead of sold is still a rental for tax purposes, and it comes with rules people are surprised by. Depreciation has to be tracked from the day it went into service, and it gets recaptured when you sell whether or not anybody ever claimed it. Not claiming it does not save you anything; it just costs you the deduction and leaves the recapture in place. Most residential rentals belong on Schedule E, and if you have lived in the property during the ownership period, the gain exclusion rules on a later sale are worth understanding before you list it, not after.

Consulting income layered on top of a W-2

Plenty of Centennial households have one salary and one contract. That combination is easier to fix than pure self-employment, because withholding on the W-2 side can be adjusted to cover the tax on the contract side and skip quarterly vouchers entirely. It is a five-minute change on a W-4 that saves a year of estimated payment deadlines, and almost nobody knows to ask for it.

Property tax across two school districts

Centennial spans more than one school district, and school district levies are the largest single component of a Colorado property tax bill. Two comparable houses a few streets apart can carry noticeably different tax bills for that reason alone. It matters on the return because state and local tax deductions are capped, so higher property tax does not translate into proportionally more federal benefit.

The Centennial problem nobody warns you about

Centennial has collected its own sales tax since 2009 rather than routing it through the state, with a city rate currently at 2.5 percent, its own retail sales tax license, and its own business registration. Confirm the current rate with the city before relying on it, because rates change by ordinance.

Here is the part that causes real trouble. A great many Centennial addresses carry Englewood, Littleton, or Aurora as the mailing city, because postal boundaries were drawn long before Centennial incorporated in 2001 and never got redrawn. The city printed on your mail is not evidence of which municipality you are in, and it is definitely not evidence of which municipality's sales tax you owe. Businesses get this wrong in both directions: some collect and remit to the wrong city for years, and others assume they are in unincorporated Arapahoe County and never register at all.

The fix is to verify by address rather than by mail. Colorado's Department of Revenue publishes a rooftop-level jurisdiction lookup, and the city can confirm its own boundaries. Do that once, write down the answer, and the problem goes away. Skip it and you can end up owing back tax to a city you did not know you were in, which is a bad conversation to have three years late.

Looking for a CPA or tax accountant in Centennial?

Worth being straight about the wording, since it is how people search. Chuck is an Enrolled Agent, not a CPA. It is a federal credential issued by the IRS, earned by examination, kept current through continuing education, and it authorizes representation of taxpayers before the IRS in any state. The focus is tax rather than accounting generally.

For an individual return, a Schedule C, a partnership, or a small S-corp, an EA and a tax-focused CPA do the same work under different letters. The genuine difference: audited or reviewed financial statements, and formal attestation for a lender, require a CPA firm, and we will say so rather than take the engagement. The longer comparison is here.

How Centennial clients actually work with us

The office is close enough that some Centennial clients still drop documents off in person, which is genuinely faster for a shoebox of paper. Everyone else uses the secure upload and handles the rest by phone. Either way the return gets read through before it is filed, and you talk to Chuck rather than to whoever picked up.

A good number of Centennial clients have been here ten years or longer, which is the part of this that does not show up in a search result. Chuck has been preparing returns since 2010 and takes a limited number of new clients each season, so calling in February beats calling in April.
