Terms of Service

1. Service description

MultiW2 is a tax planning and optimization tool designed for individuals with multiple W2 income sources. The service calculates estimated federal income tax liability, detects Social Security overpayment, recommends W-4 withholding adjustments, tracks retirement contribution limits, and plans quarterly estimated payments.

MultiW2 is not tax preparation software, not a tax advisor, and not a substitute for professional tax advice. It is a planning tool intended to help you understand your tax picture throughout the year.

2. Tax disclaimer

All calculations provided by MultiW2 are estimates based on user-provided data and published IRS rates for the 2026 tax year.

MultiW2 does not guarantee the accuracy of any calculation. Tax situations are complex and individual — factors such as state taxes, AMT, NIIT, phaseouts, and other provisions may affect your actual tax liability in ways that MultiW2 does not model.

MultiW2 is not responsible for underpayment penalties, incorrect tax filings, overpayment of taxes, or any financial losses arising from use of the tool. By using MultiW2, you acknowledge that the calculations are for planning purposes only and that you should consult a qualified tax professional for advice specific to your situation.

3. Account terms

  • One account per person. Shared accounts are not permitted.
  • You must provide accurate information when creating your account and entering financial data. MultiW2 calculations are only as accurate as the data you provide.
  • You are responsible for maintaining the security of your account credentials and for all activity that occurs under your account.

4. Subscription terms

MultiW2 offers a free tier and a paid Pro tier with two billing options:

  • Pro Quarterly: $39 per quarter, billed every 3 months.
  • Pro Annual: $99 per year, billed annually.

All payments are processed by LemonSqueezy, our Merchant of Record. Cancellation takes effect at the end of the current billing period. No refunds are issued for partial billing periods.

After cancellation, your data remains accessible in read-only mode. You can view your saved calculations and job data, but you cannot create new calculations, enter W2 data, or access Pro workflows. Resubscribing restores full access immediately.

5. Acceptable use

  • MultiW2 is for personal tax planning use only. Commercial resale of calculations, automated scraping of the service, or use of the service on behalf of others without their explicit consent is prohibited.
  • You may not attempt to bypass tier restrictions, manipulate the service, or interfere with other users' access.

6. Intellectual property

MultiW2 owns the software, design, and all intellectual property associated with the service. You own your data — all financial information you enter into MultiW2 belongs to you and can be exported or deleted at any time.

7. Limitation of liability

To the maximum extent permitted by law, MultiW2 and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, or use, arising from or related to your use of the service.

MultiW2's total liability for any claim arising from or related to the service shall not exceed the amount you paid to MultiW2 in the 12 months preceding the claim.

8. Governing law

These terms are governed by and construed in accordance with the laws of the State of Delaware, without regard to its conflict of law provisions. Any disputes arising from these terms or the service shall be resolved in the courts of Delaware.

9. Changes to these terms

We may update these terms from time to time. Material changes will be communicated to registered users via email at least 30 days before they take effect. Continued use of the service after the effective date constitutes acceptance of the updated terms.
