Why high earners switch to ExcelTax

Most tax help shows up once a year. Your income, deadlines and risks run all year. We built a system that does too.

Deadlines

4/yr

Every quarterly estimate calculated from your real books and scheduled before it is due — April, June, September and January.

Records

7yrs

Returns, receipts and workpapers kept in your Vault for seven years — longer than the standard IRS look-back window.

Support

365

A named tax pro who answers in September, not just in March — including when an IRS letter shows up.

The ExcelTax stack

Six connected modules. One tax picture.

Each module does one job well, and they share data — so the numbers that fund your estimates are the same numbers on your return and in your audit file.

Vault

Encrypted document intake. Snap a receipt, forward a 1099, upload a notice — everything lands in one organized, searchable file.

Ledger Sync

Connects your bank, cards, payroll and accounting software, then keeps categories clean month by month — not in a panic each spring.

Estimate Engine

Recalculates your federal and state estimates each quarter from year-to-date results, with safe-harbor math built in.

Filing Desk

Business and personal returns — 1040, 1120-S, 1065, 1120 and state — prepared by a pro and reviewed twice before you sign.

Audit Shield

If the IRS or your state opens an exam, we assemble your audit file and hand it to a partner CPA who represents you.

Notice Center

Upload any IRS or state letter. We tell you what it means within one business day and handle the response.

Reduce your risk of errors and missed deadlines

Penalties rarely come from one big mistake. They come from a missed quarterly payment, a 1099 that never made it onto the return, or a letter that sat unopened. ExcelTax watches all three, all year, and tells you what to do before it costs you.

How we help each client type

From scattered to sorted in four steps

Most clients are fully onboarded within two weeks. After that, the system runs in the background and we check in each quarter.

  1. Connect

    Link accounts and upload last year's returns. We flag anything missing.

  2. Review

    A strategy call to size your estimates, entity setup and biggest savings.

  3. File

    Returns prepared from books that were kept right all year, then reviewed twice.

  4. Defend

    Every return is backed by its workpapers, and a partner CPA if the IRS asks questions.
