Sioux Falls IRS Tax Audit Accountants — Local Representation, Federal Reach
South Dakota has no state income tax — but the IRS doesn't care, and the South Dakota Department of Revenue still runs aggressive sales- and use-tax audits. CPAZenith matches Sioux Falls taxpayers with local CPAs and EAs who handle both with a Form 2848 in hand.

IRS notices handled
Decode the letter — and the deadline
| Notice | What it means | Next step |
|---|---|---|
CP14 Balance due — first notice | The IRS says you owe tax. Interest and the failure-to-pay penalty are already accruing. | Verify the balance against your return, then pay, request an installment agreement, or dispute within 60 days. |
CP2000 Underreporter — income mismatch | Third-party documents (1099s, W-2s, K-1s) don't match what you filed. Not an audit — yet. | Respond by the deadline with corrected figures or supporting docs. Ignoring it triggers a statutory notice of deficiency. |
CP504 Final notice of intent to levy state refund | Account is in collections. The IRS can levy state tax refunds and will pursue further collection action. | Open a collections case: installment agreement, currently not collectible, or offer in compromise. |
LT11 / Letter 1058 Final notice of intent to levy — 30 days | The IRS can levy wages, bank accounts, and seize assets after 30 days. Triggers your CDP hearing rights. | File Form 12153 within 30 days to request a Collection Due Process hearing and pause levy action. |
Letter 525 / 915 Examination report (audit results) | Audit findings proposing changes. You have 30 days to agree, disagree, or request Appeals. | Get representation before responding. Appeals is almost always preferable to Tax Court if you disagree. |
Notice CP90 / CP297 Notice of levy on federal payments | IRS will levy Social Security, federal contractor payments, or other federal benefits. | Same 30-day CDP window. A pro can negotiate a collection alternative and request levy release. |
Resolution paths
Back taxes, installment agreements, OIC, penalty abatement & more
Back taxes & unfiled returns
File the last 6 years of missing returns first — the IRS won't entertain any resolution until you're compliant.
- Pull wage & income transcripts to reconstruct missing data
- File substitute returns over IRS-prepared SFRs (almost always lowers the balance)
- Stop the failure-to-file penalty (5% per month, capped at 25%)
Installment agreements
Monthly payment plans for taxpayers who can't pay in full but can pay over time.
- Guaranteed (under $10K) and streamlined (under $50K) plans skip financial disclosure
- Partial-pay installment agreement (PPIA) for balances you can't fully pay before CSED
- Setup fee waived or reduced for low-income taxpayers
Offer in compromise (OIC)
Settle for less than owed when reasonable collection potential is below the balance.
- Doubt as to collectibility — the most common path
- Calculated as net realizable equity + future income (12–24 mo. multiplier)
- About 30–40% acceptance rate nationally; far higher with proper Form 433 preparation
Penalty abatement
Reduce or remove failure-to-file, failure-to-pay, and accuracy-related penalties.
- First-Time Abatement (FTA) — automatic if clean compliance history for prior 3 years
- Reasonable cause — illness, natural disaster, reliance on a preparer, records destroyed
- Statutory exceptions for erroneous IRS written advice (Form 843)
Audit representation
Power of attorney (Form 2848) puts a licensed pro between you and the IRS examiner.
- Correspondence, office, and field audits — including TCMP and EITC exams
- Appeals representation if you disagree with the examination report
- Tax Court petition prep when settlement isn't possible
Currently Not Collectible (CNC)
Temporary collection hold when paying anything would create financial hardship.
- Stops levies and garnishments while in status 53
- Requires Form 433-F or 433-A financial disclosure
- CSED clock keeps running — balance can expire while in CNC

| Tax Attorney | Licensed lawyer with tax specialty. Attorney-client privilege. Required for Tax Court litigation. | Criminal exposure (eggshell audits), foreign accounts (FBAR), Tax Court cases, complex appeals. | $350–$700/hr; $7.5K–$25K+ for litigation matters |

Local context
Sioux Falls & South Dakota tax context
- South Dakota has no personal or corporate income tax — IRS resolution is the entire conversation for federal cases
- South Dakota state sales tax: 4.2% (reduced from 4.5% in 2023) + Sioux Falls 2% municipal = 6.2% combined
- SD bank franchise tax: 6% on income for state-chartered financial institutions (Sioux Falls is a major credit-card processing hub)
- SD Department of Revenue actively audits sales-tax nexus — out-of-state sellers exceeding $100K in SD sales must register
- South Dakota's lack of income tax + favorable trust laws drives in-migration; multi-state residency audits common for new arrivals

FAQ
Common questions
Why does South Dakota run sales-tax audits if there's no income tax?
Sales and use tax is the state's primary revenue source. SD DOR examiners focus heavily on contractors (services + materials), restaurants, and out-of-state sellers triggering Wayfair-era economic nexus. A local CPA who's been through these audits is worth the engagement fee.
How does the IRS handle audits in Sioux Falls?
Most Sioux Falls IRS audits are correspondence (mail-based). Field audits go through the IRS office in Sioux Falls or Aberdeen. A local POA-holder handles all interaction — you typically don't meet the examiner.
What does audit representation cost in Sioux Falls?
Correspondence audit response: $750–$1,500. Office audit representation: $2,500–$5,000. Field audit: $5,000–$15,000+ depending on years and issues. Appeals adds $2K–$5K. Most firms quote after reviewing the notice and a transcript pull.
I moved to Sioux Falls from a state with income tax — am I at audit risk?
Yes, especially for the first 1–2 years. Former-state revenue departments often challenge residency to recapture income tax. Keep a documented relocation file: SD driver's license, voter registration, lease/deed, moving receipts, and updated W-2 / 1099 addresses. A Sioux Falls CPA can pre-empt the audit before it starts.
