What Pro unlocks

💾
Saved Calculations
Every tool result saved to your dashboard. Compare S-Corp vs LLC scenarios from 3 months ago. Never recalculate from scratch.
🔍
Unlimited AI Reports
Full personalized Tax Optimization Reports normally cost $39 each. Pro gives you unlimited access — run one every quarter or every week.
📅
Quarterly Deadline Reminders
Estimated tax due dates: Apr 15, Jun 16, Sep 15, Jan 15. We'll email you 2 weeks before each one — personalized to your filing status.
🔔
Tax Law Change Alerts
When rates, brackets, or deductions change in ways that affect your saved scenarios, you'll know immediately — not at tax time.
📊
Personalized Dashboard
Your own private hub: all calculations organized by tool and date. Recommended next steps based on your situation. One URL, everything.
📈
Year-over-Year Comparison
Run the same entity comparison with this year's numbers vs last year. Track how your tax liability changes as your business grows.

Frequently asked questions

Do I need a Pro account to use the free tools?+
No. All 6 calculators and generators are completely free — no account required. Pro adds saved history, unlimited AI reports, and personalized features on top.
How do I log in? I don't see a password field.+
We use magic links — no passwords. Enter your email, we send a secure link, you click it and you're in. Your login link is valid for 1 hour.
What happens after I subscribe?+
After payment, you'll land on a welcome page. Enter your email to activate your account and we'll send a login link to your inbox. Click the link and your Pro dashboard is ready.
Can I cancel anytime?+
Yes. Cancel directly from your dashboard or email us at hello@taxstackhub.ai. No contracts, no questions asked. Your Pro access continues until the end of the billing period.
Is my financial data private?+
Yes. Your saved calculations are tied to your account and never shared. We don't sell data. The numbers you run stay yours. See our privacy policy for full details.
Is this a replacement for a CPA?+
No — and we say that clearly. Tax Stack Pro is the intelligence layer between DIY guessing and paying $5,000+ for CPA advice. Use it to understand your situation, model scenarios, and go into CPA meetings better prepared. See our AI disclaimer.

The gap between DIY and CPA
doesn't have to cost $5,000
