How do IRS examination status calls generate billing gaps for tax controversy attorneys?

IRS field examinations generate billing gaps because the 12–24-month audit cycle produces a long series of status calls that arrive on the IRS examination team's schedule — document request deadlines, IDR (Information Document Request) responses, examination team availability for taxpayer interviews — rather than the attorney's billing calendar. The IRS Revenue Agent calls the attorney with a new IDR, schedules a taxpayer interview, or requests extension documentation without advance notice synchronized to the attorney's billing practice. At the start of the examination, the taxpayer calls the attorney immediately upon receiving the IRS CP2000 correspondence notice or the Form 4549 Income Tax Examination Changes: 'I got a letter from the IRS saying I owe $240,000 — what is this?' The attorney begins substantive IRS correspondence analysis on that call without a billing matter open. Examination status call types: (1) IDR receipt and response planning call (20–35 min) — when the IRS issues a new Information Document Request, the attorney evaluates the scope of the IDR (IRC § 7602 summons authority vs. voluntary cooperation), the taxpayer's documentation availability, and whether a Taxpayer Advocate referral is warranted; (2) RAR (Revenue Agent Report) preliminary discussion call (25–40 min) — the IRS Revenue Agent may conduct informal preliminary discussions with the attorney about proposed adjustments before issuing the formal RAR; these calls contain substantive concession and negotiation content but precede any formal written response; (3) Appeals conference preparation calls (20–30 min each) during the 30–60-day window between the 30-day letter and the Appeals conference; the attorney and client conduct preparation calls on the client's availability schedule; (4) TEFRA partnership audit coordination calls (20–35 min) — large partnership examinations under TEFRA (I.R.C. §§ 6221–6234) involve a Tax Matters Partner and multiple partner calls that arrive across the extended 3–5-year partnership audit cycle. At 55% untracked: 15 examinations × 8 calls × 30 min × 55% = 33 hours = $9,900–$16,500/year at $300–$500/hr. IRS Appeals conference preparation adds 10 appeals matters × 4 calls × 25 min × 55% = 9.2 hours = $2,750–$4,583/year. IRS examination gap: $9,900–$16,500/year (combined with Appeals: $12,650–$21,083/year).

How do Tax Court petition preparation calls generate billing gaps during the 90-day window?

The 90-day statutory notice of deficiency window under I.R.C. § 6213(a) — the period within which the taxpayer must file a Tax Court petition to preserve Tax Court jurisdiction — generates a concentrated billing gap because the client calls immediately upon receiving the Statutory Notice of Deficiency (SNOD, CP3219A), and the attorney begins substantive legal analysis under time pressure without a Tax Court billing matter yet open. The SNOD triage call (30–50 min) is the most systematically underlogged event in Tax Court practice: the attorney reviews the SNOD adjustment summary, evaluates the tax year at issue and the 90-day deadline calculation (or 150-day deadline if the notice was sent to a taxpayer with a foreign address under § 6213(a)), and advises whether to petition the Tax Court, accept the deficiency and pay, or wait for additional IRS review. Tax Court petition preparation call types: (1) SNOD triage and Tax Court jurisdiction evaluation call (30–50 min) — the attorney evaluates the adjustment and advises on Tax Court vs. refund-suit litigation strategy (the taxpayer cannot both petition the Tax Court and sue for a refund in the same proceeding); (2) Tax Court petition drafting status calls (15–25 min each) — as the attorney drafts the Tax Court petition under Tax Court Rule 34, the client calls with document questions and fact clarifications that the petition must accurately state; (3) IRS Counsel settlement branch calls (20–35 min each) — Tax Court cases settle at a high rate (approximately 90%) through the IRS Office of Chief Counsel docketed case settlement process; settlement calls arrive when the IRS Counsel attorney assigned to the docket has availability, not when the taxpayer's attorney is available; (4) Stipulated Decision evaluation call (25–40 min) — when the parties reach a settlement, the Stipulated Decision document must be reviewed for mathematical accuracy and scope of settlement before the taxpayer signs. At 55% untracked: 10 Tax Court matters × 6 calls × 35 min × 55% = 19.25 hours = $5,775–$9,625/year. Tax Court gap: $5,775–$9,625/year.

How do Offer in Compromise calls generate billing gaps on the IRS case worker's schedule?

Offer in Compromise (OIC) practice under I.R.C. § 7122 — submitting an OIC based on doubt as to collectibility, doubt as to liability, or effective tax administration — generates billing gaps because the IRS OIC Examiner calls on the IRS's processing schedule, which is typically 12–24 months after the initial OIC submission, and the calls arrive without advance scheduling synchronized to the attorney's billing calendar. The OIC process also generates interim advisory calls when the client calls to ask about the status of the pending OIC, the effect of the OIC on the Collection Statute Expiration Date (CSED) under I.R.C. § 6502(a), or whether a Lien Notice (NFTL) filing while the OIC is pending affects the OIC's viability. OIC call types: (1) financial analysis and OIC eligibility call (25–40 min) — the attorney conducts the Reasonable Collection Potential (RCP) analysis under IRM § 5.8.4.4 (net equity in assets + future income component based on 12 or 24 months of future income depending on the OIC type); these calls require access to the client's financial records in real time and generate 2–3 calculation calls before the OIC is submitted; (2) IRS OIC Examiner call-back (20–35 min) — the OIC Examiner calls from the Brookhaven, Memphis, or Cincinnati IRS campus on a schedule the attorney cannot anticipate; the Examiner may request updated bank statements, vehicle NADA values, or business equipment appraisals within a 14-day deadline; (3) Collection Due Process hearing coordination calls (25–35 min) — when the IRS issues a Final Notice of Intent to Levy (CDP notice, Letter 1058), the attorney has 30 days to request a Collection Due Process hearing under I.R.C. § 6330; CDP hearing preparation generates 3–5 calls in the 30-day window; (4) PPIA (Partial Payment Installment Agreement) status calls (15–25 min each) — when an OIC is rejected and the taxpayer enters a PPIA under I.R.C. § 6159, monthly status calls track the CSED and the PPIA payment compliance. At 60% untracked: 20 OIC and CDP matters × 6 calls × 30 min × 60% = 36 hours = $10,800–$18,000/year. IRS Installment Agreement monitoring adds 15 IA matters × 3 calls × 20 min × 55% = 8.25 hours = $2,475–$4,125/year. OIC and collection gap: $13,500–$22,500/year.

Tax controversy attorney time tracking: IRS examination status calls, Tax Court petition preparation, and Offer in Compromise monitoring

Q: What role does the IRS whistleblower program play in tax controversy billing?

IRS whistleblower claims under I.R.C. § 7623(b) — the mandatory award provision for claims resulting in collected proceeds exceeding $2 million — generate an extended advisory call structure because the IRS Whistleblower Office processes claims over a 5–10-year period, and status calls arrive at IRS processing milestones that are unpredictable and unscheduled from the attorney's perspective. The initial Form 211 submission call (35–50 min) is the most substantive advisory event: the attorney evaluates the quality of the claimant's information (specificity, plausibility, materiality) and advises whether the claim meets the § 7623(b) threshold analysis for a mandatory award. Subsequent calls: IRS acknowledgment and claim number assignment call (15–20 min); annual status inquiry call to the Whistleblower Office (20–30 min); IRS audit results determination call (20–35 min) when the IRS informs the claimant that an examination based on the whistleblower claim is ongoing; award determination call (30–45 min) when the IRS issues a preliminary award determination under Treas. Reg. § 301.7623-2 and the claimant must decide whether to file a Tax Court petition for award review under § 7623(b)(4). At 55% untracked: 8 whistleblower matters × 4 calls × 30 min × 55% = 8.8 hours = $2,640–$4,400/year — a smaller but structurally distinct call gap that compounds across a 5-year claim timeline.

Tax controversy practice — IRS field and correspondence examinations, Tax Court petitions, Collection Due Process hearings, Offer in Compromise submissions, and IRS Appeals conferences — generates three billing-gap sources driven by IRS administrative schedules rather than the attorney's billing calendar: IRS examination status calls during the 12–24-month audit cycle (15 examinations × 8 calls × 30 min × 55% untracked = $9,900–$16,500/year at $300–$500/hr), Tax Court petition preparation calls during the 90-day deficiency notice window (10 matters × 6 calls × 35 min × 55% untracked = $5,775–$9,625/year), and Offer in Compromise and Collection Due Process coordination calls on the IRS case worker's schedule (20 matters × 6 calls × 30 min × 60% untracked = $13,500–$22,500/year). For a solo tax controversy attorney, the annual billing gap is $35,000–$65,000.

TL;DR

ClaimHour captures every IDR-receipt call before the formal examination response is drafted, every SNOD triage call during the 90-day Tax Court window, and every OIC Examiner call-back when the IRS campus calls — passively, no timer, no audio, no call contents. $29–$59/mo. No PMS required.

IRS examination: status calls during the 12–24-month audit cycle

IRS field examinations generate billing gaps because the 12–24-month audit cycle produces a long series of status calls that arrive on the IRS examination team's schedule — document request deadlines, IDR response windows, Revenue Agent availability for taxpayer interviews — rather than any billing calendar the attorney controls. The IRS Revenue Agent calls with a new Information Document Request, schedules a taxpayer interview, or requests extension documentation without advance notice synchronized to the attorney's billing practice. The examination also generates client status calls: the taxpayer calls when an IRS notice arrives in the mail, when the IRS Revenue Agent sends an email, or when the taxpayer's CPA (who is handling the accounting response) calls the attorney to coordinate the legal strategy.

IRS examination call types: (1) IDR receipt and response planning call (20–35 min) — when the IRS issues a new Information Document Request under I.R.C. § 7602 summons authority, the attorney evaluates the scope of the IDR, identifies any privileged or work-product-protected documents in the request, and advises the taxpayer on the response strategy; the attorney also evaluates whether the IDR timeline justifies a filing of a Taxpayer Advocate Service referral under I.R.C. § 7811; (2) Revenue Agent Report preliminary discussion call (25–40 min) — the IRS Revenue Agent may conduct informal preliminary discussions with the attorney about proposed adjustments before issuing the formal RAR; these calls contain substantive concession and negotiation content but precede any formal written response and any billing entry for the examination adjustment response; (3) IRS Appeals conference preparation calls (20–30 min each) — once the taxpayer receives the 30-day letter following the RAR, the 30–60-day IRS Appeals conference preparation window generates 3–5 status calls between the attorney and the client on the client's availability schedule; (4) Partnership examination coordination calls (20–35 min) — TEFRA partnership audits under I.R.C. §§ 6221–6234 involve Tax Matters Partner calls and individual partner notification calls that arrive across the 3–5-year partnership audit cycle. At 55% untracked: 15 examinations × 8 calls × 30 min × 55% = 33 hours = $9,900–$16,500/year. IRS Appeals conference preparation adds 10 appeals × 4 calls × 25 min × 55% = 9.2 hours = $2,750–$4,583/year. IRS examination gap: $9,900–$16,500/year.

State and local tax examination calls — state income tax, sales and use tax, and property tax audits — generate a parallel call structure on the state revenue department's examination schedule. State examination cycles are typically 3–5 years; the attorney advising on a combined IRS and state examination carries two overlapping call structures with different audit timelines and different examiner contacts.

Tax Court petition: 90-day deficiency window preparation calls

The 90-day statutory notice of deficiency window under I.R.C. § 6213(a) generates a concentrated billing gap because the client calls immediately upon receiving the Statutory Notice of Deficiency (CP3219A) — and the attorney begins substantive legal analysis under time pressure without a Tax Court billing matter yet open. The SNOD triage call is the most systematically underlogged event in Tax Court practice: the attorney reviews the adjustment summary, evaluates the 90-day deadline calculation, and advises on Tax Court vs. refund-suit litigation strategy in a single call that generates no billing entry because no engagement has been formalized for Tax Court representation.

Tax Court petition preparation call types: (1) SNOD triage and Tax Court jurisdiction evaluation call (30–50 min) — the attorney evaluates the proposed adjustment, determines whether the deficiency amount and the tax years at issue make Tax Court cost-effective vs. accepting the deficiency and paying (and later suing for a refund in the Court of Federal Claims or a federal district court), and explains the jurisdictional election the taxpayer is making; (2) Tax Court petition drafting calls (15–25 min each) — as the attorney drafts the Tax Court petition under Tax Court Rule 34, the client calls with documentary clarifications (the taxpayer's name as it appears on the return, the exact tax year at issue, the IRS's docket office address for the specific SNOD); these drafting calls are underlogged because they feel like administrative coordination rather than legal advice; (3) IRS Counsel settlement branch calls (20–35 min each) — Tax Court cases settle at approximately 90% through the IRS Office of Chief Counsel docketed settlement process; settlement calls arrive when the IRS Counsel attorney assigned to the docket has availability; the attorney cannot schedule these calls in advance; (4) Branerton conference and trial preparation calls (20–35 min) — if the case does not settle and proceeds to trial, the pre-trial Branerton conference (Tax Court Rule 110) generates a concentrated call cluster in the 30 days before the trial date. At 55% untracked: 10 Tax Court matters × 6 calls × 35 min × 55% = 19.25 hours = $5,775–$9,625/year. Tax Court preparation gap: $5,775–$9,625/year.

Offer in Compromise and collection: calls on the IRS case worker's schedule

Offer in Compromise (OIC) practice under I.R.C. § 7122 generates billing gaps because the IRS OIC Examiner calls on the IRS's processing schedule — typically 12–24 months after the initial OIC submission — and the calls arrive without advance scheduling synchronized to the attorney's billing calendar. The IRS campus examiners at Brookhaven (for regular mail submissions), Memphis, and Cincinnati call during IRS business hours from blocked or unidentified numbers; the attorney must take the call immediately because missed IRS calls require a return-call process through the IRS switchboard that can delay the OIC processing by weeks.

OIC and collection call types: (1) financial analysis and Reasonable Collection Potential calculation call (25–40 min) — the attorney conducts the RCP calculation under IRM § 5.8.4.4 using the client's Quick Sale Value of assets, equity in assets, and future income component; these calculations require access to the client's financial records in real time and generate 2–3 preparatory calls before the OIC is submitted; (2) IRS OIC Examiner call-back (20–35 min) — the OIC Examiner calls to request updated financial statements (within 14 days), NADA-listed vehicle values, or business equipment appraisals; the attorney takes the call and advises the Examiner on what can be provided within the deadline; (3) Collection Due Process hearing preparation calls (25–35 min each) — when the IRS issues a Final Notice of Intent to Levy (Letter 1058 or LT11) triggering the CDP hearing right under I.R.C. § 6330, the attorney has 30 days to file a CDP hearing request; CDP hearing preparation generates 3–5 concentrated calls in the 30-day window where the attorney evaluates the collection alternative arguments (installment agreement, OIC, uncollectible status, or penalty abatement) available in the CDP hearing under Treas. Reg. § 301.6330-1; (4) PPIA and Installment Agreement status calls (15–25 min each) — ongoing installment agreement clients call monthly when a payment is made or when a payment is missed; the attorney advises on the default cure options under I.R.C. § 6159(b) before the IRS terminates the IA and resumes collection. At 60% untracked: 20 OIC and CDP matters × 6 calls × 30 min × 60% = 36 hours = $10,800–$18,000/year. Installment Agreement monitoring adds 15 IA matters × 3 calls × 20 min × 55% = 8.25 hours = $2,475–$4,125/year. OIC and collection gap: $13,500–$22,500/year.
