Tax preparation, planning, and IRS defense — all in one hub
Tax has three jobs: file accurately, plan proactively, and defend when challenged. This hub maps the six paths most owners need — from filing a Schedule C to defending an IRS field audit to building a 5-year entity strategy.

Credentials
CPA vs EA vs Tax Attorney — who do you need
Three credentials have unlimited IRS representation rights. The right one depends on whether you need filing, advisory, or litigation.
- CPA — broadest scope: returns, audits, attest, advisory, tax court (with USTCP)
- Enrolled Agent (EA) — federally licensed, tax-only, often more affordable
- Tax Attorney — required for tax court, fraud, criminal exposure, complex M&A
- PTIN-only preparer — limited rights; appropriate only for simple 1040s
Entity tax
Which return to file and when
Entity type drives both the form and the due date. Late-filing penalties on a 1120-S are $245 per shareholder per month — easy to avoid.
- 1040 / Schedule C — sole proprietor, April 15
- 1065 — partnership/LLC, March 15
- 1120-S — S-corp, March 15
- 1120 — C-corp, April 15 (calendar year)
- Quarterly estimates — April 15, June 15, Sept 15, Jan 15
Resolution
When you owe the IRS more than you can pay
Most resolution outcomes fall into one of five buckets. Avoid 'pennies-on-the-dollar' marketing — only about 30% of OIC submissions are accepted.
- Installment agreement — under $50K, automatic for individuals
- Offer in Compromise — only if total assets + future income < liability
- Currently Not Collectible — temporary hardship status, accrues interest
- Penalty abatement — first-time abate is automatic if compliant 3 prior years
- Innocent spouse relief — for liabilities tied to a former spouse
Planning
The five moves that move the needle
Most year-end tax savings are decided in October and locked by December 31. These are the levers that actually compound.
- S-corp election once net profit clears ~$60K
- Solo 401(k) or SEP-IRA — up to $69,000 (2024) employer contribution
- Augusta rule — 14 days of tax-free home rental
- Cost segregation on commercial real estate over $500K basis
- QBI deduction (Section 199A) — 20% off pass-through profit

FAQ
Common questions
How much does a CPA charge to prepare a tax return?
1040 with a Schedule C runs $400–$1,200. An S-corp return (1120-S) is $1,200–$2,500. A partnership (1065) is $1,500–$3,500. Multi-state and consolidated returns scale from there. Hourly rates for advisory work are $200–$450.
When should I switch from a tax preparer to a CPA?
Any time you have a business entity, rental property, K-1 income, or stock-based compensation. Preparers are fine for W-2 + standard deduction. The breakpoint is usually $200K AGI or any 1099/K-1 income.
How do I respond to an IRS audit letter?
Do not ignore it — the response window is 30 days. Engage a CPA, EA, or tax attorney with audit experience before you reply. Most audits are correspondence audits (mailed letter) and can be resolved by documenting the items in question.
What is tax planning vs tax preparation?
Tax preparation files what already happened. Tax planning changes what's about to happen — entity choice, retirement contributions, asset timing, depreciation elections. Planning generates 5–15x ROI; preparation alone usually breaks even on fees.
Can a CPA negotiate with the IRS on my behalf?
Yes — CPAs, EAs, and tax attorneys have unlimited representation rights granted under Circular 230. They can sign Form 2848 (Power of Attorney) and handle all communication with the IRS for you.
