IRS notices & your QuickBooks books: what to do (and who does what).
You got an IRS notice — a CP2000 underreporting notice, a balance due, a math or return-change notice, an information-return mismatch (like 1099s), or a payroll-tax notice — and it often traces back to the books behind the return. TechBrot is a bookkeeping and advisory firm — not the IRS, not a CPA, EA, or tax attorney. We do not respond to the IRS, file or amend returns, represent you, or give tax or legal advice. What we do: reconcile and correct the QuickBooks books behind the notice and assemble clean, documented figures your licensed professional uses to respond.

§ TL;DR
An IRS notice — a CP2000 underreporting notice, a balance due, a math or return-change notice, an information-return mismatch (such as 1099s), or a payroll-tax notice — often traces back to the bookkeeping behind the return: income or expenses miscategorized, 1099s that don’t match, payroll records off, or a return that didn’t tie to the books.
TechBrot is a bookkeeping and advisory firm — not the IRS, and not a CPA, EA, or tax attorney. We do not respond to IRS notices, file or amend returns, represent you before the IRS, negotiate, or give tax or legal advice. What we do is reconcile and correct the QuickBooks books and records behind the notice and assemble clean, documented figures your CPA, EA, or tax attorney uses to respond.
§ 01 · Where it traces back to the books
IRS notices that trace back to the books.
The notice is the symptom; the books are often the source. These are the bookkeeping problems most commonly sitting behind an IRS notice — the part we reconcile so your licensed professional can respond.
Notice 01 · Underreported income vs. deposits (e.g. a CP2000)
A CP2000 underreporting notice says the income reported to the IRS doesn’t match the return. Behind it, the books are often the issue: deposits that weren’t all recorded as income, transfers booked as revenue, or sales that never tied to what hit the bank. Reconciling deposits to recorded income shows what the real number is — the figure your professional needs to respond.
Notice 02 · 1099 or information-return mismatch
The IRS matches the 1099s and other information returns it receives against the return. When a 1099 you received doesn’t match what you recorded, or 1099s you issued don’t tie to what you actually paid contractors, a mismatch notice follows. The fix in the books is to reconcile vendor payments and the 1099s to the underlying transactions.
Notice 03 · Payroll-tax discrepancy
A payroll-tax notice flags an employment-tax difference — wages, withholding, or deposits that don’t reconcile. Payroll-tax matters are serious because of trust-fund exposure, so a licensed professional should be involved immediately. In the books, we reconcile payroll records, wage totals, and tax liabilities so the figures your professional responds with are correct.
Notice 04 · A return that didn’t tie to the books
Sometimes the return was filed from figures that never matched the bookkeeping — a P&L that didn’t reconcile, prior-year balances that were off, or numbers entered without support. When the IRS adjusts or questions it, the first job is to tie the books to reality so your professional can see the true picture and respond.
Notice 05 · Expense and categorization issues
Expenses miscategorized, personal and business mixed, or deductions booked where they don’t belong can drive a balance-due or return-change notice. Correcting the categorization in QuickBooks and documenting the support gives your CPA, EA, or tax attorney an accurate expense picture to work from — we don’t decide what’s deductible; that’s their call.
Common · Missing or incomplete records
When the records behind a period are incomplete — missing months, unreconciled accounts, gaps in documentation — the notice can’t be answered confidently because no one can prove the numbers. Rebuilding and reconciling the period so the figures are documented and defensible is the bookkeeping work that has to happen before a response is solid.
§ 02 · What to do
What to do — and who does what.
Five steps, in order. Note the division of labor: your CPA, EA, or tax attorney owns the response and any deadline; we own the books and the documented figures behind it.
- 1
Don’t ignore the deadline
An IRS notice has a response window, and missing it can forfeit options or escalate the matter. Read the notice, note the deadline, and don’t set it aside. You don’t have to have the answer today — but the clock is real, and the next step is getting it to the right person fast.
- 2
Give the notice to your CPA, EA, or tax attorney
The response, any amended return, the representation, the negotiation, and any tax or legal advice are your licensed professional’s job — not ours. Hand them the notice. If you don’t have one, this is the moment to engage a CPA, enrolled agent, or tax attorney; for a payroll-tax notice, do it immediately.
- 3
We reconcile the period’s books and assemble documented figures
In parallel, we reconcile the period the notice covers inside your QuickBooks file — correcting miscategorized income and expenses, tying 1099s and payroll records to what actually happened, and reconciling accounts — then assemble a clean, documented support package. That’s the accurate, defensible set of numbers your professional needs to respond.
- 4
Your licensed professional responds and represents you
With accurate books in hand, your CPA, EA, or tax attorney writes the response, files or amends if needed, and deals with the IRS directly — including any representation or negotiation. That is their authorized work. We don’t contact the IRS on your behalf and we don’t advise you on tax or law.
- 5
We get the books right behind them
Once the immediate notice is handled, we finish getting the books right so the same issue doesn’t recur — cleaning up the categorization, the 1099 process, and the reconciliation going forward. Accurate books are the best defense against the next notice. We fix the books; your licensed professional handles anything with the IRS.
One thing that can’t wait: if the notice is a payroll-tax matter, treat it as urgent. Unpaid trust-fund payroll taxes (the income tax and the employee share of FICA withheld from paychecks) carry serious personal exposure — the IRS can assess responsible people individually. Get a CPA, EA, or tax attorney involved immediately on the response, and have us reconcile the payroll records behind it in parallel.
§ 03 · When to call
Three signals it’s a ProAdvisor call.
The notice says your books are wrong
The IRS is questioning income, expenses, 1099s, or payroll that trace straight back to the bookkeeping — and the books can’t prove the right number today. That’s a reconciliation job before your professional can respond: tie the period to reality and document it so the figures are defensible.You need the period reconciled fast for your CPA
Your CPA, EA, or tax attorney is on the deadline and needs accurate, documented figures now. A free file review followed by a focused diagnostic gets the period reconciled and the support package assembled quickly — so your professional isn’t responding from numbers no one can stand behind.It’s a multi-year mess
The notice exposed books that are behind across multiple years — unreconciled accounts, miscategorized history, returns that never tied. That’s cleanup work, not a quick patch. We scope and rebuild the books so this notice, and the years behind it, rest on figures that hold up.§ 04 · Software, or the books?
When an IRS notice is no longer a software problem.
A notice is answered by your CPA or other licensed professional. When the figures behind it came out of QuickBooks, whether those figures were right is a bookkeeping question.
- The period in the notice was never reconciled.
- Payroll or 1099 totals in QuickBooks do not agree with what was filed.
- The same problem appears to run across more than one year.
Start with the free QuickBooks file review — a limited review that identifies likely issues and the information needed for a written scope, with the findings in plain English. If the findings show that the books themselves need work, that is QuickBooks cleanup, quoted as a fixed fee against a written scope before any work starts.

§ 05 · Who does what
Your licensed professional responds; a ProAdvisor gets the books right behind it.
The line is bright and we hold it. The response to the IRS, any amended return, the representation, the negotiation, and any tax or legal advice belong to your CPA, enrolled agent, or tax attorney — licensed professionals who are authorized to do that work. We are not, and we won’t pretend to be. What a Certified QuickBooks ProAdvisor does is the bookkeeping underneath: reconcile the period the notice covers, correct miscategorized income and expenses, tie the 1099s and payroll records to what actually happened, and assemble clean, documented figures — the support package your professional uses to respond accurately. We work to a written scope and we coordinate directly with your professional when they want us to. Independent firm — not the IRS, not a CPA, EA, or tax attorney; an Intuit account or billing matter stays with Intuit.

§ 08 · Questions
What people ask about IRS notices and the books.
Is this the IRS’s or Intuit’s official support?
No. TechBrot is a bookkeeping and advisory firm — not the IRS, not a CPA, EA, or tax attorney, and not Intuit’s official software support. Contacting us reaches no government agency. This page is a QuickBooks ProAdvisor reference and is educational only. For an Intuit account, login, subscription, or billing matter, contact Intuit directly.
Do you respond to the IRS or represent me?
No — your CPA, EA, or tax attorney does; we fix the books behind it. We do not respond to IRS notices, file or amend returns, represent you before the IRS, or negotiate. Those are the authorized work of a licensed professional. What we do is reconcile and correct the QuickBooks books behind the notice and assemble clean, documented figures your professional uses to respond.
Is this tax or legal advice?
No, this is educational only. Nothing on this page is legal or tax advice, and it is not a substitute for a CPA, enrolled agent, or tax attorney. It explains how an IRS notice can trace back to bookkeeping and what TechBrot does and does not do. For advice on your specific notice, the response, and any representation, consult your licensed professional.
How does an IRS notice trace back to my QuickBooks books?
Behind most notices is a set of books, and the books are often where the problem started: deposits not all recorded as income, expenses miscategorized, 1099s that don’t tie to what was paid, payroll records that are off, or a return that didn’t reconcile to the bookkeeping. Reconciling the period shows the true, documented figures — the basis your professional needs to respond.
I got a CP2000 underreporting notice — can you help?
We can help with the part underneath it: reconciling deposits to recorded income and tying the figures to what actually happened, so the real number is documented and defensible. We do not respond to the CP2000 or contact the IRS — your CPA, EA, or tax attorney does that, using the reconciled, documented figures we assemble.
What about a payroll-tax notice?
Treat it as urgent. Unpaid trust-fund payroll taxes — the income tax and employee FICA withheld from paychecks — carry serious personal exposure, and the IRS can assess responsible people individually. Get a CPA, EA, or tax attorney involved immediately on the response. In parallel, we reconcile the payroll records behind the notice so your professional works from accurate figures.
What does it cost to get the books behind a notice reconciled?
We start with a free file review. From there, a focused diagnostic to reconcile the period behind the notice is a fixed-fee scope from $1,200, and a full cleanup runs $1,200–$15,000+ if the books are behind across multiple periods. Written scope before any work begins. The response and representation are separate — that’s your licensed professional’s engagement, not ours.
Can you talk to the IRS or my CPA for me?
We don’t contact the IRS — that’s your CPA, EA, or tax attorney’s authorized role. We’re glad to coordinate directly with your professional when they want us to, handing over the reconciled books and the documented figures they need. The division is simple: we fix the books; your licensed professional handles anything with the IRS.
