Meet IRS requirements for business tax compliance

IRS CP501, CP503 and CP504 arrive in a fixed sequence — CP504 is the Notice of Intent to Levy, and the final notice gives 30 days to file Form 12153.

An IRS Form 4564 Information Document Request is a request, not a court order — answer only what's asked, keep a copy of everything, and ask for time early.

One missed Form 941 deposit draws a 2–15% IRS failure-to-deposit penalty, and unpaid trust fund taxes can become 100% personally yours under the TFRP.

Volunteer hours are worth $0 on your return, but the IRS lets you deduct 14 cents a mile, supplies, and uniforms — and two 2026 changes shrink who benefits.

A PTIN, an EFIN after a 45-day IRS suitability check, and Form 8867 diligence on every credit return — the federal startup checklist for paid preparers.

After the IRS cut 28% of its workforce, phone waits doubled to 14 minutes, paper processing slowed to 36 days, and audit revenue fell 35%. The small-business playbook is to e-file everything, use the Business Tax Account, respond to notices online, and keep audit-ready books.

An IRS Identity Protection PIN is a free six-digit code that blocks anyone from e-filing a federal return with your Social Security number. Here is who can get one, the three ways to request it, how it works for spouses and dependents, and the errors that cause rejections every filing season.

Section 7611 lets the IRS examine a church only after a high-level Treasury official records a reasonable belief in writing, sends two separate notices, and agrees to finish within two years and stay away for five. This guide walks through each stage, the pre-examination conference, the five exceptions that remove the protection entirely, and the three bookkeeping failures that trigger most church inquiries in practice, namely unrelated business income, informal payroll, and campaign intervention.

Under Section 7502 a return mailed on or before its due date is deemed filed on the postmark date — but only if it actually arrives, and a postage-meter date never counts. Since December 24, 2025, USPS postmarks reflect regional processing rather than deposit, so certified mail or a free manual postmark is the proof that holds.

An IRS Letter 2800C orders you to withhold at a rate the agency sets, effective no sooner than 60 days out, and an employer who keeps withholding at the old rate is liable for the tax that should have been withheld. Here is the response checklist, the two narrow exceptions, and how to convert a pre-2020 allowance-based lock-in for modern payroll software.

If a payroll company withdraws your tax money and never deposits it, the employer still owes the full tax plus penalties. A payroll service provider or reporting agent assumes no liability, a Section 3504 agent shares it, and only an IRS-certified CPEO is solely liable for its work-site employees. This guide covers the Trust Fund Recovery Penalty that reaches owners personally, seven warning signs of a failing provider, and the monthly EFTPS verification habit that catches a missed deposit at a 2% penalty instead of 10%.

EPCRS gives small business 401(k) sponsors three ways to fix plan mistakes — self-correction with no fee, no filing, and no IRS contact through the third plan year for significant errors, a voluntary filing with IRS approval, or a negotiated closing agreement on audit — with standard fixes for late deferral deposits, missed eligible employees, plan loan failures, and missed RMDs.
