Preparation resource. Editorial review: November 3, 2026. This guide helps organize records and questions; it does not determine your tax position. Use the agency instructions for the relevant year and obtain advice for your circumstances.
Records to organize
Prepare the records that relate to your situation and keep the original supporting statements. Use the same filing year or clearly labelled periods so the reviewer can follow the history.
- All Forms 1099-INT and year-end statements
- Account ownership and original-currency records
- Prior-year adjustments that may affect the current statement
How to use these records
Separate ordinary interest, tax-exempt interest, penalties and foreign tax shown on the statements. A missing information form is not proof that interest is unreportable. Include foreign accounts in a separate disclosure inventory even when they earned nothing.
The question to resolve before filing
Does the list include every account and distinguish US interest from foreign-account reporting questions?
Start with the facts you can support. Identify missing statements, corrections and earlier filings instead of filling a gap with an estimate that has not been discussed. Tell the team which countries, tax years and agencies are involved so the engagement can cover the right work.
A mistake to avoid
Do not assume an account has no reporting relevance because it paid little or no interest.
A clear handoff to your preparer
- Label the evidence. Keep each record with its relevant year, account or activity.
- List open questions. Share missing information and anything that differs from the prior return.
- Confirm the scope. Ask which returns, disclosures and follow-up work are included before preparation begins.
Do not enter identity numbers, account numbers, verification codes or tax-document copies in a public enquiry. Use your private client portal for requested records after onboarding.
Official starting points
Use the current agency guidance and the instructions for the applicable filing year. A source link is not confirmation that a particular rule, election or claim applies to your circumstances.
