Big Book of Taxes 365 Online Version

Regular price $ 95.00

The Big Book of Taxes 365 > Online Tax Research Edition.

Part quick reference guide, part tax research platform, the Big Book of Taxes 365 was designed for the tax professional on a limited research budget, though powerful enough to add to any tax research library.

In an era of constantly changing tax laws, paper-based quick reference guides have become obsolete. On top of that, Congress has decided to make changes retroactive. Bottom line, a printed tax reference guide may be worthless by the time the ink dries.

This online research tool includes over 150 chapters within 1,250 plus pages, covering everything individual tax with highlights of small business issues.


The Big Book of Taxes has our constantly updated research center, which links to over 300 sites, including IRS forms, the IRM, Code, Regs, Rev Rulings, Rev Procs, bulletins, draft forms, tax treaties, state tax agencies, K-1s for publicly traded partnerships, per diem rates, SS administration, and the list goes on and on.

Many tax professionals spend thousands of dollars on tax research products. The Big Book of Taxes is designed as the cliff-notes of tax law, basically the same result as having a staff of full-time tax technical researchers.

The format and table of contents follow the 1040, making it easy to navigate.

In addition, you can use quick search queries, flow charts, worksheets, indexes, and note tools to make the Big Book of Taxes 365 an unmatched tool.

"The Big Book is the most complete reference manual I’ve seen. My experience and background, not surprisingly, make it easier to use. It’s really very accessible. Amazing depth, as well as the unbelievable breadth and ClientWhys, updates it as relevant pronouncements come out, daily when necessary. WOW! What an undertaking! It looks fantastic." Phil Storrer, CPA

"I love the online version of the Big Book. The fact that it’s continuously updated is an amazing perk that cannot be duplicated in a print edition. And many publishers don’t even update their digital versions, so what we have in the online Big Book is a tremendously useful and unrivaled tax tool. Thanks, Lee!" Matt Bigelow
