Frequently Asked Questions

Ask Us What You Want To Know From Us

What documents are needed to prepare a business tax return?
You’ll need your year-end financial statements (profit and loss, balance sheet), prior year tax return, payroll records, depreciation schedules, 1099s issued and received, and any details on owner distributions or contributions.
How are business losses handled on a tax return?
Loss treatment depends on your entity type. For partnerships and S-Corps, losses may pass through to owners' personal returns, subject to basis and at-risk rules. C-Corps carry losses forward or back, per IRS rules.
Do I need to file in every state where I make sales?
Not necessarily. Filing is typically required if your business has nexus in a state, such as physical presence, employees, or significant economic activity. We determine filing requirements based on each state's specific thresholds.
How often should estimated tax payments be made for businesses?
Corporations usually pay estimated taxes quarterly. Pass-through entities may also need quarterly payments to avoid penalties, depending on income levels. We help you calculate and schedule these to avoid underpayment issues.
