Do Business Owners Need to Make Quarterly Estimated Taxes and How Much Should You Pay?
Four invisible bills on your calendar. Do nothing, and penalties add interest. Use safe harbors to make them optional.
Summary of What This Blog Covers
- Who must pay quarterlies, who can skip
- Safe harbor (100%/110%) vs current-year (90%)
- Cash-flow friendly system + examples + checklists
Who Actually Needs to Make Estimated Taxes?
Generally yes if profit > $400. Skip if withholding covers liability or no tax due last year.
How Much Should You Pay?
Safe harbor: 100%/110% of last year’s tax.
Current-year: 90% of this year’s tax.
Annualized: pay when income arrives.
A Practical System You Can Run
Monthly funding to tax account → quarterly payments on autopilot. Blend with W-4 bump.
Worked Examples
Last year $24k tax, AGI $210k → safe harbor $26.4k total.
Lumpy income → annualize to match timing.
