Business Tax Preparation · Verified Directory
Business Tax Preparation — LLCs, S-Corps, Partnerships & C-Corps
Business returns are unforgiving — wrong entity election, missed K-1 deadline, or under-withheld estimates can cost more than the return itself. CPAZenith connects you with CPAs and EAs who file 1120, 1120-S, 1065, and complex Schedule C returns every season — and represent clients when the IRS comes calling.
Problems we solve
Common tax problems we solve
Tax issues rarely fix themselves. A tax resolution specialist reviews your situation, files missing returns, and negotiates the best path forward with the IRS or state agencies.
- You owe back taxes to the IRS or state
- You received a notice or lien and are not sure what to do
- Payroll taxes were not filed or paid correctly
- Previous returns contain errors or missing deductions
- You need a payment plan or offer in compromise
- An audit or examination is pending
- You are not confident your books are tax-ready
What's included
What business tax preparation includes
Federal & state returns
1120 (C-Corp), 1120-S (S-Corp), 1065 (partnership/multi-member LLC), Schedule C — federal and every state you have nexus in.
K-1 issuance
Partner and shareholder K-1s issued by deadline. Every K-1 matched to ownership %, basis, and distribution tracking.
Quarterly estimates
1120-W, 1040-ES projections that hit safe harbor without overpaying — recalculated mid-year as numbers change.
Owner compensation strategy
Reasonable W-2 wages for S-Corp owners, 199A QBI optimization, retirement contribution layering.
IRS notice & audit support
Built-in resolution support — if the IRS questions the return, the prep firm represents you.
Extensions & late-file rescue
Form 7004 extensions and reasonable-cause letters for missed deadlines (penalty: $245/partner or shareholder/month).
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
Who you hire matters
CPA vs Enrolled Agent vs Tax Attorney
| Type | Scope of practice | Best for | Typical cost |
|---|---|---|---|
| CPA | Unlimited IRS representation. Strongest on tax planning, business returns, and complex accounting. | Business owners, multi-entity filers, anyone whose case crosses tax + accounting + financial statements. | $200–$450/hr; $2K–$10K typical resolution engagement |
| Enrolled Agent (EA) | Federally licensed by the IRS, unlimited representation rights. Tax-only focus. | Personal collections cases, installment agreements, OIC, audit representation when no litigation risk. | $150–$300/hr; $1.5K–$6K typical resolution engagement |
| 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 |

FAQ
Common questions
When are business tax returns due?
S-Corps (1120-S) and partnerships (1065): March 15. C-Corps (1120) and Schedule C sole props: April 15. All extendable six months via Form 7004 — but extensions delay filing, not payment.
What does business tax preparation cost?
Schedule C / single-member LLC: $400–$900. Partnership 1065: $900–$2,500. S-Corp 1120-S: $1,200–$3,500. C-Corp 1120: $1,500–$5,000+. Multi-state, consolidated, or international filings cost more.
What if my business owes more than I can pay?
Pay what you can with the return, then set up an installment agreement immediately. For balances under $25K, online payment agreements are usually approved within minutes. Larger balances require Form 433-B financial disclosure.
Do I need separate preparation and resolution firms?
Not usually. Most full-service business CPAs handle both — they already have your books and entity history, which makes resolution faster and cheaper than starting fresh elsewhere.
How to choose
How to choose a tax-resolution professional
Use these criteria to compare candidates side by side and avoid the most common hiring mistakes.
Industry concentration
Ask how many clients in your industry they currently serve. Generalists miss niche credits, filings, and software conventions.
Credentials and licensure
Verify active CPA license, Enrolled Agent status, or relevant certifications (QuickBooks ProAdvisor, Xero Partner, AFSP).
Software stack
Confirm they work in your existing platforms — QuickBooks Online, Xero, Gusto, Sage Intacct — rather than forcing a migration.
Engagement scope and SLAs
Get a written engagement letter that lists deliverables, monthly close date, response times, and what is and isn't included.
Pricing transparency
Prefer fixed monthly fees over open-ended hourly billing for recurring work. Ask what triggers a price increase.
References and reviews
Ask for 2–3 current client references in your industry, plus check independent reviews and state-board status.
