Does every small business make estimated payments?

No. Requirements depend on business and owner circumstances, tax, withholding, and current law.

Can I use last year’s payment amount?

Ask the CPA whether a prior-year method applies and whether current income or tax changes require an update.

What proof should I retain?

Keep the calculation, approval, payment confirmation, date, amount, tax period, and related IRS notice.

Estimated Tax Payments: Questions to Review With Your CPA

October 4, 2026 · Small Business tax guide · 2 min read

Some owners and self-employed people may need to make estimated tax payments during the year. The right approach depends on income, withholding, entity and owner circumstances, prior tax, and current rules. Ask the CPA to explain the applicable calculation and keep a calendar rather than relying on memory.

Identify who may owe payments

Ask how the business’s legal structure affects entity-level obligations and the owner’s personal estimated taxes. Do not assume every LLC or corporation has the same payment responsibility.

Document the calculation and assumptions

Record projected income, withholding, credits, prior-year figures, safe-harbor assumptions if relevant, and the source used. Ask how large changes in revenue, deductions, or ownership alter the estimate.

Schedule dates and approvals

Put due dates, responsible preparer, reviewer, payment method, and confirmation storage in a shared calendar. Allow time for cash planning and record the transaction in the accounting system.

Revisit after major changes

Ask the CPA when forecasts should be refreshed, such as after a strong quarter, new owner draw, asset sale, or payroll change. Keep notices and payment confirmations with the year’s tax file.

Tax rules and thresholds can change and depend on individual facts. Confirm dates and calculations with the IRS and a qualified tax professional for the applicable tax year.

Use the directory search to find options, then confirm details with the relevant professional or official source. See IRS estimated taxes for individuals.
