IT Support for Accounting Firms in Denver, CO
A Denver CPA practice files federal and Colorado returns against the same April 15 deadline, tracks a city head tax and home-rule sales tax for its business clients, and keeps every bit of it in software that cannot fail in March. NetSys runs the IT underneath, from preparer laptops to client portals, remotely from our Brooklyn office and month to month.
The short answer
NetSys provides IT support and managed IT for Denver accounting and CPA firms: an engineer-staffed help desk, Microsoft 365 and laptop management, multifactor authentication, secure client file exchange, ThreatDown endpoint protection, tested backups and the written information security program the FTC Safeguards Rule calls for. All of it is delivered remotely: we never send a technician to a Colorado office, and new preparer laptops ship ready to sign in. Someone picks up every day between 2 a.m. and 9 p.m. Mountain, deadline weekends included, and the fee is set per user each month once we have assessed the firm.

What a Denver tax season asks of a firm's IT
Colorado individual returns are due on April 15 with the federal return, so a Denver practice has one hard peak instead of the staggered state deadlines some firms juggle. Business clients bring work that is particular to the city. Denver levies an occupational privilege tax: $5.75 a month withheld from each employee who earns at least $500 there, plus $4.00 a month paid by the business, with monthly returns once an employer has ten or more staff. Denver is also a home-rule city that administers its own sales and use tax, and it appears on the state's list of jurisdictions in the Colorado Sales and Use Tax System. Every one of those filings means another portal, another set of credentials and more client bank details moving through the firm. Many preparers also spend part of the season working from home in Highlands Ranch, Arvada or Aurora. We give each of them a managed laptop, keep portal and e-Services credentials in Keeper behind multifactor authentication, limit client folders to the engagement team and send every return through a secure portal or encrypted message instead of a plain attachment.
How remote IT support carries a Denver practice through April
Everything we do for a Denver firm happens remotely, and we say so before an agreement is signed: no NetSys engineer will come to your office. For an accounting practice that matters less than partners expect. A tax application that refuses to open, a scanner that stopped saving to the client folder, a manager locked out of the portal or a print queue that stalled on a Saturday are all fixed over a remote session. Seasonal staff receive laptops enrolled through Windows Autopilot, with the tax software, mapped folders and printers waiting at first sign-in, and those machines can be wiped and returned when the season closes. Brooklyn runs two hours ahead, so our engineers are already working when the earliest Denver preparer logs on, and calls are answered between 2 a.m. and 9 p.m. Mountain. A ransomware alert or an email outage in deadline week goes straight to your dedicated engineer.
Client data, payment fraud and the Safeguards program
A CPA firm holds the records criminals want most: Social Security numbers, bank routing details, payroll registers and years of prior returns. The usual loss starts with a convincing email, not an attack on the tax software. We put Barracuda filtering and DMARC on your domain, block automatic forwarding to outside mailboxes, require number-matching multifactor prompts, and write a callback rule for any change to a client's or vendor's bank instructions. KnowBe4 training runs before January, when phishing lures about IRS notices and refund status pick up. Access is reviewed each quarter and removed the day someone leaves. We keep the Qualified Individual named in your written program informed of what changed, what was blocked and what still needs a decision, so the plan on file matches the controls actually running.
Backups and the late-season storms Denver gets
Front Range weather has a habit of arriving close to the deadline. The March 13 to 14, 2021 blizzard left 27.1 inches at Denver International Airport and kept its runways shut into Monday afternoon. On April 6 and 7, 2024, eight days before the federal filing date, Xcel Energy cut power to about 55,000 customers in its first public safety power shutoff, and wind damage pushed the total past 150,000 across nine counties. A firm whose files live in Microsoft 365 and whose staff carry managed laptops keeps working through both. We back up mail, SharePoint and OneDrive independently of Microsoft, protect any on-premises tax database with Datto or Veeam and an immutable copy held outside Colorado, and run a test restore every December so the first real one is never in April.

Rules that shape IT for Denver accounting firms
FTC Safeguards Rule (16 CFR Part 314)
Tax preparers count as financial institutions under the Gramm-Leach-Bliley Act, so a CPA firm needs a written information security program overseen by a Qualified Individual, a written risk assessment, access controls, encryption of customer information and multifactor authentication. Firms holding information on fewer than 5,000 consumers are excused from some provisions, not the whole rule. Since May 13, 2024, a notification event involving at least 500 consumers must be reported to the FTC within 30 days of discovery.
IRS Publications 4557 and 5708
The IRS tells tax professionals they are required to keep a written information security plan and to review and test it regularly. Publication 5708, released in August 2024, is a template written for smaller practices; Publication 4557 explains the safeguards behind it, including multifactor authentication and how to report client data theft to the IRS. We keep your plan aligned with the tools in place so an examiner sees a document that describes your office.
Colorado record disposal, security and breach notice
Under C.R.S. 6-1-713, 6-1-713.5 and 6-1-716, Colorado requires a written policy for destroying paper and electronic records with personal identifying information once they are no longer needed, reasonable security procedures, and contracts that hold service providers to the same standard. After a breach, affected Colorado residents must be told no later than 30 days after the firm determines it occurred, and the Attorney General as well once 500 or more residents are involved. This is general information, not legal advice.

Accounting Firms in Denver: FAQs
Who provides IT support for accounting firms in Denver?
NetSys does, remotely from our office in Brooklyn. We run IT for accounting and CPA practices around the way they work: preparer laptops, access to tax and practice-management software, document storage, client portals, email security, backups and the written security plan that ties it together. Partners get an account manager whose cell number they can call directly, and the engineers who answer have degrees in electrical or electronics engineering or computer science, plus Cisco and Microsoft certifications. The agreement runs month to month.
How does IT support work for accounting firms in Denver?
Preparers and partners call, email or message engineers directly, every day between 2 a.m. and 9 p.m. Mountain, the weekends before April 15 included. NinjaOne and Intune manage the computers, Microsoft Entra ID the identities and Keeper the shared credentials, which is why almost every problem is solved over a remote session. Nobody from NetSys travels to Denver; a replacement laptop arrives ready to use, and your office manager plugs in anything physical while an engineer talks them through it.
What does IT support cost for a CPA firm in Denver?
The fee is a monthly amount per user, worked out after we assess the practice, and there is no public rate card. For a Denver firm it moves with partner and staff headcount, the number of seasonal preparers who join each year, whether the tax software runs on a server you own or in the vendor's cloud, the security tools included and how much written-program and audit-evidence work you want from us. A one-time project such as moving a file server into SharePoint gets its own quote once it is scoped. Nothing locks the firm into a multi-year contract.
How do you help Denver CPA firms meet the FTC Safeguards Rule?
We begin with the written risk assessment the rule requires, then put the controls in place and document them: multifactor authentication on every account that reaches client data, encryption on laptops and in email, access limited to the clients each person serves, logging, tested backups and yearly security training. Your written program names the Qualified Individual and describes those controls as they actually run. When something changes, such as a new client portal or a departing partner, we update the program with it.
Do you support our tax and practice-management software?
Yes, at the layer beneath the application. We keep the server or cloud access it needs working, schedule updates outside deadline weeks, give its database a separate backup, and when the program itself breaks we raise the ticket with its maker and stay on the call until it works. We do not resell or license tax software. Document management, e-signature and portal tools get the same care: we secure the accounts and devices and deal with each vendor directly so partners are not on hold.
How do you handle seasonal staff and remote preparers?
Every seasonal hire gets a firm-owned laptop or an Azure Virtual Desktop session, a named account with multifactor authentication, access only to the client folders assigned to them and an end date set on the first day. Personal computers never touch tax software or client files. When the season wraps up, accounts are disabled, laptops are wiped remotely and shipped back, and the access review is filed with your security program, which is the record an examiner or insurer will ask to see.
