Business tax preparation playbook

What goes into a clean business tax filing

Business entity types

Your entity determines the form you file, how owners are taxed, and which planning levers are available. The right CPA matches the entity to your stage and goals — and re-evaluates the choice each year as your business grows.

Sole proprietor — Schedule C on the owner's 1040, self-employment tax on all profit
Single-member LLC — disregarded entity by default, same as Schedule C
Multi-member LLC / partnership — Form 1065 with K-1s to each partner
S-Corporation — Form 1120-S, reasonable W-2 wages plus distributions
C-Corporation — Form 1120, flat 21% federal rate, dividends taxed at owner level

Filing timelines

Business returns operate on a different calendar than personal ones. Missing a deadline triggers per-month, per-shareholder/partner penalties that compound quickly. A business tax pro tracks every due date for your entity, state, and any registered foreign jurisdictions.

March 15 — S-Corp (1120-S) and partnership (1065) returns due
April 15 — C-Corp (1120) and sole proprietor returns due
Sept 15 — Extended S-Corp and partnership returns due
Oct 15 — Extended C-Corp and sole proprietor returns due
Quarterly — Estimated payments (April 15, June 15, Sept 15, Jan 15)
Jan 31 — W-2s and 1099-NEC issued to recipients and the IRS

Tax preparation checklist

The fastest, cheapest engagements are the ones where the client shows up organized. Before your first meeting, pull the items below so your CPA can spend the time on strategy rather than chasing documents.

Prior-year federal and state business returns
Year-end financial statements: P&L, balance sheet, trial balance
Bank and credit card statements (Dec 31 closing balances)
Payroll year-end reports, W-3 summary, and 1099-NEC reconciliations
Fixed asset additions and disposals with purchase invoices
Loan statements with year-end principal balance and interest paid
K-1s received from any partnerships or S-Corps you own
Major events: ownership changes, new states, M&A activity

CPA matching: finding the right fit

Business tax work is specialty work. A boutique that runs SaaS S-Corps all day will outperform a generalist for a venture-backed startup — and a construction-focused firm will know percentage-of-completion accounting cold. Match by industry, entity type, and engagement size; verify license; confirm fees up front; and test communication before signing.

Specialty match — industry, entity type, and growth stage fit
License verification — active CPA or EA confirmed with the state board
Fee transparency — fixed-fee, hourly, or value-based, scope clearly defined
Communication cadence — quarterly check-ins or annual-only engagement
Technology stack — alignment with your accounting and payroll systems

Common questions

About business tax services

When are business tax returns due?+

S-Corps and partnerships file by March 15, C-Corps and sole proprietors by April 15. All can extend six months — but extensions only delay filing, not payment.

Should my business be an S-Corp?+

Once your net profit consistently exceeds ~$50K, an S-Corp election typically saves meaningful self-employment tax. A business tax pro can model the breakeven for your situation.
