Clear answers before you calibrate your paycheck.

Withholdwise is a private federal and state withholding planner. It uses your pay, withholding, income changes, and planning details to estimate whether your current withholding may be drifting from your target. It is educational planning software, not tax preparation or tax filing software.

It is a withholding calculator and planning tool, not a tax return product. Withholdwise can help you review paycheck withholding, compare safe-harbor planning benchmarks, and prepare questions or W-4 planning notes. It does not prepare, sign, or file a federal or state tax return.

Yes. Owing money when you file does not by itself mean an underpayment penalty applies. Federal rules include payment benchmarks, but eligibility and exceptions depend on income, filing status, installment payments, withholding, and other facts. Check current IRS Topic 306, Publication 505, and Form 2210; a screening estimate cannot guarantee whether a penalty applies.

Yes. You can upload a text-based paystub or photo for browser-based extraction of gross pay, federal/state withholding, and detected pre-tax deductions (401k, HSA, health insurance). Always review every detected value in the planner to ensure your pre-tax and bonus inputs are complete.

The paystub parser extracts current and year-to-date gross pay, federal withholding, state withholding, federal taxable wages, and common pre-tax deduction line items (401k, HSA, FSA, health insurance). When pre-tax deductions are detected, Withholdwise automatically populates them and expands the pre-tax accordion so you can verify your baseline.

Withholdwise is designed to process paystub information in your browser whenever possible. The paystub parser does not need your Social Security number. Local scenarios, pulse history, and Pro status may remain in browser storage. Redact SSNs, bank details, addresses, and employee IDs before uploading.

Yes. PNG, JPG, JPEG, and WEBP images can be read with an in-browser OCR engine. Use a sharp, well-lit, flat image with the entire statement visible. Shadows, folds, glare, handwriting, and very small print can reduce accuracy. Always compare the detected values with the original statement.

Withholdwise does not ask you to send the PDF password. Open the statement in your PDF reader, save an unlocked copy—often through File → Print → Save as PDF—and upload the unlocked copy. You can also enter the values manually.

Enter the values manually using the planner. A failed extraction is intentional when the statement is unreadable, uses an unusual layout, or produces inconsistent current and year-to-date amounts. This protects you from relying on an incorrect prefill.

Quarterly is a practical review cadence. Recheck after a raise, bonus, job change, RSU vest, marriage, new dependent, major deduction change, or substantial 1099 or side-hustle income. Your employer payroll settings and personal tax facts can change the result.

Yes. Add additional W-2 or spouse income in the planner, and use the bonus, RSU, and self-employment fields for other income. For self-employment planning, you can enter expenses or business miles. Keep records and consult a tax professional for filing decisions.

The planner uses planning benchmarks such as 90%, 100%, and 110% of estimated tax liability to help frame potential exposure. These are screening signals, not a guarantee that you will avoid a penalty or owe a particular amount. IRS rules and individual circumstances determine the applicable requirement.

No. Withholdwise provides estimates and planning signals based on the information you enter. Bonuses, credits, deductions, state rules, investment income, self-employment, and other facts can materially change a final tax result. Use the estimate to decide what to review, not as a guaranteed balance due.

It provides educational W-4 planning guidance and a downloadable summary. It does not replace IRS instructions, employer payroll guidance, or advice from a qualified tax professional. Review any change with the appropriate source before submitting a new W-4.

No. The core planner is available without an account. Authentication is requested when you begin a Pro checkout so the purchase can be associated with your account.

Use Portable Vault in the Track tab. You can save an encrypted 256-bit AES vault directly into your local Google Drive, Dropbox, or iCloud folder, allowing seamless cross-device sync without uploading your data to remote cloud servers.
