Effective March 1, 2026 — Last updated March 16, 2026
This Service Level Agreement ("SLA") outlines TaxBlitz's commitments to platform availability, support response times, and remedies for service disruptions. This SLA applies to all paid plans, with enhanced commitments for Enterprise customers.
TaxBlitz commits to 99.9% uptime for the core platform, measured monthly. Uptime is calculated as: (Total Minutes − Downtime Minutes) / Total Minutes × 100.
Scheduled maintenance windows are excluded from downtime calculations. Maintenance is performed during off-peak hours (Sundays 2:00–6:00 AM ET) with at least 48 hours advance notice.
Availability applies to the TaxBlitz web application, REST API, and IRS filing services.
If monthly uptime falls below the 99.9% commitment, Enterprise plan customers are eligible for service credits:
| Monthly Uptime | Service Credit |
|---|---|
| 99.0% – 99.9% | 10% of monthly fee |
| 95.0% – 98.99% | 25% of monthly fee |
| Below 95.0% | 50% of monthly fee |
TaxBlitz provides tiered support based on issue severity and customer plan:
| Severity | Description | Free | Starter | Professional | Enterprise |
|---|---|---|---|---|---|
| Critical (P1) | Platform unavailable, filing failures | 24 hours | 8 hours | 4 hours | 1 hour |
| High (P2) | Major feature degraded | 48 hours | 24 hours | 8 hours | 2 hours |
| Medium (P3) | Non-critical issue | 72 hours | 48 hours | 24 hours | 8 hours |
| Low (P4) | Question or enhancement | 5 days | 3 days | 2 days | 1 day |
TaxBlitz makes commercially reasonable efforts to ensure forms submitted at least 48 hours before IRS deadlines are transmitted on time.
TaxBlitz is not liable for IRS system outages, delays in IRS processing, or failures caused by incorrect data provided by the customer.
Customers are responsible for data accuracy, timely submission, and maintaining valid TIN/EIN information.
All customer data is encrypted at rest (AES-256) and in transit (TLS 1.3).
PII data (SSN, EIN, financial amounts) is encrypted at the field level using AES-256-GCM.
Automated daily backups are retained for 30 days. Point-in-time recovery is available within the 30-day window.
Data retention defaults to 7 years (configurable per organization). Data is securely purged after the retention period expires.
This SLA does not apply to: (a) features labeled beta or preview; (b) outages caused by customer misuse, third-party integrations, or force majeure events; (c) Free tier accounts; (d) scheduled maintenance windows.
Service credits must be requested within 30 days of the incident. Credits are applied to future invoices and are not redeemable for cash.
TaxBlitz may update this SLA with 30 days written notice to Enterprise customers. Continued use after the notice period constitutes acceptance of the updated terms.
