GrantExtension vs. TaxZerone
TaxZerone has one of the cleaner interfaces in the cheap tier and "Tax Time Twins" bundles that pair a 4868 with a 7004 or 8868. But on price, GrantExtension goes lower — Form 7004 / 8868 at $9.95 each, one flat fee with no return purchase required.
Price per form
| Form | GrantExtension | TaxZerone |
|---|---|---|
| Form 4868 (personal) | Not offered this season | $11.99 |
| Form 7004 (business) | $9.95 | $17.99 |
| Form 8868 (nonprofit) | $9.95 | $14.99 |
Competitor prices verified from TaxZerone's site as of October 2026 (4868 $11.99 / 7004 $17.99 / 8868 $14.99). TaxZerone lists 7004/8868 free only if you also prepay the underlying 1120-S/1065/990 return with them — a bundling play, not a standalone price.

Where GrantExtension wins
- Lower standalone price — Form 7004 $9.95 vs. $17.99, and 8868 $9.95 vs. $14.99.
- No return purchase required — our low price is the standalone price, not a bundling hook.
- One flat fee shown before you pay, for every form we file.
- A clean, mobile-first 5-minute flow with instant IRS confirmation.
- Your SSN or EIN is encrypted at rest, never shown in full after filing, and deleted 3 years after the return's due date.
When TaxZerone may fit better. If you're already filing the underlying return (1120-S, 1065, or a 990) with TaxZerone, its bundled free extension can be the cheaper path. For a standalone extension at the lowest flat price, GrantExtension wins.
