Quarterly Taxes
Connect your accounting software and let TaxVault automatically calculate your quarterly taxes, generate IRS forms, and send payment reminders.
What Are Quarterly Taxes?
When you work for yourself (freelancer, contractor, small business owner), no one withholds taxes from your paycheck. Unlike W-2 employees, you're responsible for paying your own taxes directly to the IRS.
The IRS doesn't want to wait until April to get paid—they require self-employed people to pay estimated taxes four times per year:
These payments include both income tax and self-employment tax (15.3% for Social Security & Medicare). If you don't pay enough, the IRS charges penalties.
✅ TaxVault calculates exactly what you owe based on your actual income and expenses—no guessing, no surprises.
The Problem We Solve
Entrepreneurs face a unique quarterly tax nightmare that existing solutions ignore
Underpayment Penalties
The IRS penalizes estimated tax underpayment at ~8% annually. Guessing wrong costs you real money.
Variable Income Chaos
Freelancers and business owners have unpredictable revenue, making quarterly estimates pure guesswork.
Deadline Confusion
Four quarterly deadlines (Apr 15, Jun 15, Sep 15, Jan 15) are easy to miss, triggering penalties.
Manual Calculations
Most entrepreneurs use spreadsheets or guess, leaving money on the table or risking penalties.
