Business Tax Preparation
1120, 1120-S, 1065, Schedule C — filed to withstand audit.
Overview
Business returns are where preparer skill matters most: entity classification, reasonable compensation, basis tracking, accountable plans, and §199A optimization each move the tax number by thousands. Our senior accountant and IRS-registered tax professionals prepare and review every return we file, and every client gets a year-end planning conversation before we lock the return.

Frequently Asked Questions
When are business tax returns due?
S-corporations and partnerships file by March 15 (Form 1120-S / 1065). C-corporations file by April 15 (Form 1120). Extensions add 6 months but don't extend payment deadlines.
What is reasonable compensation for an S-corporation owner?
The IRS requires S-corp owner-employees to pay themselves 'reasonable compensation' via W-2 before taking distributions. We benchmark against RCReports and industry data, document the analysis, and defend it if challenged.
Do you file returns for multi-member LLCs?
Yes. Multi-member LLCs default to partnership taxation and file Form 1065 unless they elect S-corp or C-corp treatment. We handle the entity classification decision as part of onboarding.
Can you prepare returns in a state we're not registered in but have nexus in?
Yes — with a nexus review first. Many growing businesses discover they've triggered filing obligations in states they never registered in; we prepare the returns and often pair with a Voluntary Disclosure Agreement to limit look-back exposure.
