The problem
You guess at quarterlies, lose track of deductions you might qualify for, and hand your CPA a pile of raw data in March that costs $400/hr to assemble.
Most US SMBs overpay quarterly estimated taxes — because they're guessing. The default IRS method (safe-harbor on prior year) leaves cash sitting at the Treasury earning nothing, when that cash could be running your business.
Worse: deductions get missed. Mileage. Home office. R&D. Section 179. Half the deductions a small business is entitled to require active tracking through the year — you can't reconstruct them in March.
And when March hits, your CPA wants a stack of artifacts: the M-1 book-to-tax differences worksheet, depreciation schedules, 1099s for every contractor you paid, exhibits for every deduction. Without these, the CPA bills you to assemble them — at $300–$500/hr.
How Tax Prep solves it
The Tax Prep Support Agent calculates estimate figures from actual income and expenses, surfaces potential deductions as you go, and prepares the M-1 worksheet your CPA needs at year-end — so your CPA reviews and approves rather than re-keys. It does not provide legal or tax advice.
The Tax Prep Support Agent calculates your federal and state quarterly estimate figures from actual income and deductions — not from last year's number. It prepares an estimate figure for the quarter so you and your CPA can decide what to send the IRS. It does not provide legal or tax advice.
As you go, it surfaces potential deductions. Mileage from your calendar. Home office from your business address. Software subscriptions categorized correctly. Section 179 candidates flagged. Every potential deduction captured during the year, not reconstructed in March.
At year-end, the agent prepares a CPA-ready tax package: M-1 worksheet showing book-to-tax differences, depreciation schedules, 1099s for every contractor paid over $600, deduction exhibits with source receipts attached. Your CPA reviews, approves, and signs; they don't re-key.
