GrantExtension vs. TaxExtension.com
TaxExtension.com is the premium brand leader — 25+ years, four pricing tiers, and state-extension resources for all 50 states. GrantExtension skips the tiers and upsells: one flat fee per extension — Form 7004 / 8868 at $9.95 each — for the same core job, done faster.
Price per form

| Form 7004 (business) | $9.95 | $24.95+ (tiers) |
| Form 8868 (nonprofit) | $9.95 | Not offered |
Competitor prices verified from TaxExtension.com's site as of October 2026. It sells in tiers — personal from $19.95, business from $24.95 (Professional tiers run $49.95 / $59.95) — so the real cost depends on the tier and add-ons you pick. It does not offer Form 8868 (personal and business tiers only).

Where GrantExtension wins
- Far lower price for the same core filing — Form 7004 at $9.95 vs. $24.95+ on a paid tier.
- One transparent flat fee — no Free/Essential/Premium/Pro tiers to decode or upsell into.
- A fast, mobile-first flow focused on getting the extension filed, not selling add-ons.
- Your SSN or EIN is encrypted at rest, never shown in full after filing, and deleted 3 years after the return's due date.
- Money-back guarantee if the IRS rejects a return we can't fix.
When TaxExtension.com may fit better. If you want 50-state coverage in one place or 24/7 in-season support, and you don't mind paying a premium for the brand, TaxExtension.com delivers. If you just want your federal extension filed cheaply and quickly, GrantExtension is the simpler, lower-cost path. TaxExtension.com and FileLater are run by the same company (InterSearch Tax Solutions), so comparing one covers the other.
