One question at a time
Start with what you want to understand about the move. Note where existing records are held and how you’ll reach the people or providers who can supply them after you leave.
Make a research planChoose a concrete starting point: a pay record, the period it covers, or a question about working in more than one place. Keep your question alongside the records you already have.
Make a research planSeparate the things you want to understand—an account, a retirement plan, a home or a business. Give each question its own place in your notes before looking for a specific answer.

About three minutes. No email, documents or exact amounts required. Preliminary only—not tax advice. This public check does not prepare or file a tax return.
There isn’t a published guide for this direction yet. Start with the research plan above or the preliminary diagnostic; we won’t send you to a draft article.
