Kynth Quarterly Taxes vs Keeper
You shouldn't have to prepay a year of tax software to see the quarterly math.
Keeper is one of the best-known tools for self-employed taxes: it tracks and uncovers business deductions automatically, analyzes your return for missed opportunities, and includes federal and state e-filing with a max refund guarantee — with a 1:1 accountant on Premium and up. It's billed annually: $199, $399, or $1,199 a year depending on plan. Kynth Quarterly Taxes takes the quarterly-estimate job specifically: it connects to your bank feed and books, finds the deductions you're leaving on the table, and computes each estimate with the math laid out and the payment amount ready at every deadline — it drafts and organizes for your review, and filing stays with you or your CPA. Here's the honest comparison.

No success fee, no usage meter, no demo call. 30-day money-back guarantee.
The honest math: Keeper Standard is $199 a year prepaid; Kynth Quarterly Taxes is $19 a month — about $228 if you keep it all year, and nothing if you only need it through a rough quarter. Keeper's fee includes e-filing your return; Kynth's includes drafting every estimate with the math shown, a free manual tier, and a 30-day money-back guarantee. Pick by the job, not the sticker.
The honest recommendation
- You want your annual return e-filed inside the same product that tracked your deductions — filing is Keeper's headline feature and Kynth doesn't file.
- You want a 1:1 dedicated accountant answering questions through the year, which Keeper includes from Premium up.
- You prefer one prepaid annual fee that covers deduction tracking and tax season together.
- The quarterly estimates are the actual pain — you want each one computed with the math laid out and the payment amount ready at every deadline, then reviewed by you or your CPA.
- You want monthly billing and a free manual tier instead of a $199+ annual prepay for a job that peaks four times a year.
- You'd rather prove it works first — the live demo runs on sample data with no account or card, and the 30-day money-back guarantee covers the rest.
