Business Tax Compliance FAQs

Clear answers to common questions we receive from business owners and finance teams.

When are business tax returns due?
C corporation returns (Form 1120) are due by the 15th day of the fourth month after the tax year ends. S corporation returns (Form 1120-S) and partnership returns (Form 1065) are due by the 15th day of the third month after the tax year ends. Extensions are available and move the filing deadline by six months respectively.
What happens if we need more time to file?
Extensions can be filed to extend the deadline for submitting your return. Extensions do not extend the time to pay tax owed. If tax is due, estimated payments should be made by the original deadline to avoid penalties and interest.
How do you handle multi-state tax filings?
We analyze business activity by state to determine filing requirements, calculate apportionment using state-specific methods, and prepare required state returns. Nexus is reviewed annually to identify new obligations or changes in filing status.
Do our financial records need to be finalized before tax preparation?
Yes. Accurate tax returns require accurate financial records. Books should be closed, reconciled, and reviewed before tax preparation begins. If adjustments are needed, we identify those early in the process.
What documentation do you need to prepare our business return?
We typically need finalized financial statements, prior-year tax returns, depreciation schedules, loan documents for interest deductions, records of major asset purchases or disposals, and relevant legal or transaction documents from the tax year.
What makes your compliance work different from other firms?
We treat every return as if it will be examined. That means comprehensive documentation, written support for material positions, and technical accuracy that goes beyond basic form completion. The goal is work that stands up under review.
Do you handle sales tax and other business compliance beyond income tax?
Yes. We can support sales tax compliance, business personal property tax, annual 1099 filing, payroll tax returns, and other regulatory requirements depending on your needs.
