Tax document checklist by entity type

The right document request depends entirely on what you're filing. Here's exactly what to ask for by return type — individual, S-corp, C-corp, partnership, and sole proprietor — so nothing gets missed and nothing extra gets asked for.

A generic “please send your tax documents” request is one of the biggest reasons clients send back the wrong thing, or send it in three separate emails over two weeks. The fix is a request tailored to the return being filed. Below is a working checklist for the five most common entity types — general reference, not a substitute for judgment on any specific client's situation. Prefer an interactive version?

Individual (Form 1040)

A standard individual return. What you need scales with the client’s situation — a W-2 employee needs far less than someone with investment income, rental property, or dependents’ education expenses.

W-2sFrom every employer during the tax year.
1099-NEC / 1099-MISCFreelance, contractor, or miscellaneous income.
1099-INT / 1099-DIV / 1099-BInterest, dividends, and brokerage sales (with cost basis).
1099-R / SSA-1099Retirement distributions and Social Security benefits.
Prior-year tax returnEspecially important for new clients.
Schedule K-1sIf the client is a partner, S-corp shareholder, or trust beneficiary.
Form 1098Mortgage interest statement.
Property tax statementsFor itemizing or state-specific credits.
Form 1098-EStudent loan interest paid.
Form 1098-TTuition statement, for education credits.

S-Corporation (Form 1120-S)

A pass-through business return. Beyond standard bookkeeping records, S-corps require close attention to shareholder compensation, distributions, and basis — the areas the IRS scrutinizes most.

Prior-year returnForm 1120-S and all schedules.
Profit & loss statementFull-year income and expenses.

Business formation documentsArticles of incorporation, S-election (Form 2553) for new clients.

C-Corporation (Form 1120)

A standalone taxable entity. C-corp collection leans heavily on financial statements, dividend activity, and debt schedules, since the corporation — not its owners — bears the tax.

Bank and credit card statementsAll business accounts, full year.

Profit & loss statementFull-year income and expenses.

Using these lists in practice

The most common mistake isn't missing an item — it's sending every client the same list regardless of entity type, which produces confusion on the client's end and incomplete uploads on yours. Start from the relevant list above, trim it to what actually applies to that client's situation, and send one complete request instead of a rolling series of “oh, and one more thing” follow-ups. For the workflow that turns a list like this into a request clients actually complete, read the complete document-collection guide or the practical playbook for ending the chase.

Not tax advice. This checklist is a general reference for what to request from clients, not a substitute for professional judgment on any specific return, jurisdiction, or client situation.

Frequently asked questions

Does every client need every document on their entity’s list?
No — these lists cover the documents that commonly apply, but not every client will have every item. A W-2 employee with no investments needs a fraction of the full individual list, while an S-corp with multiple shareholders and financed equipment will need most of its list. Treat each list as a starting menu to select from, not a mandatory checklist for every client.
What’s the difference between requesting documents for a new client vs. a returning one?
New clients need a prior-year return (and sometimes prior-year workpapers) so you can verify carryforwards, depreciation schedules, and basis. Returning clients usually just need the current year’s documents, since you already have their history on file.
Can one client need documents from more than one list?
Yes — a common example is someone who owns an S-corp and also has personal investment income, or a sole proprietor who is also a partner in another business. In those cases, combine the relevant items from each entity’s list into one request rather than sending separate ones.
