What to prepare

For overall return preparation, start with the general checklist. Additional documents depend on your income and the services you need.

General document checklist

How we determine the scope

After a general description of your situation, we identify which areas need to be reviewed together and which involve separate reporting or another tax year.

Helpful resources

Children, dependents, and tax credits: documents that may be needed

If children, dependents, or credits are claimed, the facts of the year and supporting records should be reviewed before filing.

Form 1095-A and Marketplace health insurance

If you had health insurance through the Marketplace during the year, Form 1095-A is important for reviewing the return. Form 8962 is used when the Premium Tax Credit must be calculated or advance credit payments must be reconciled.

Tax filing extension: Form 4868

Form 4868 can provide additional time to file an individual federal tax return, but it does not extend the time to pay tax.

Selling a home: tax records that may matter

A home sale is not reviewed from the sale price alone. The return may depend on whether the property was your main home, how long you owned and used it, adjusted basis, and whether you received Form 1099-S.

How it works

Common questions

This is my first U.S. tax return. Where do I start?

Start with a short description of your situation: status, income sources, family/dependents, states of residence, and any foreign income or accounts.

Which services are outside your scope?

The main focus is U.S. individual tax returns. Payroll, sales tax, corporate returns, and full bookkeeping are not included in standard Form 1040 preparation. If a matter is outside our scope, we will say so before preparation begins.

When do I need to reach out early rather than wait until the last minute?

The tax filing season generally begins in the second half of January. It is better to reach out early for 1099 / Schedule C work, Marketplace coverage, foreign income or accounts / FBAR, multiple states, complex child or dependent situations, an IRS letter, or prior-year returns. These situations often require additional fact and document review.
