Depending on your employment, and other factors, you may have to fill out a number of forms. For instance, if you were employed, you would have to fill out a Form W-2. If you were unemployed, you would need to fill out a 1099-G. If you were self-employed, you will need Forms 1099, Schedules K-1, and income records to verify amounts not reported on 1099-MISC or 1099-NEC, among other documents. However, more forms may be needed if you have had certain life events or have a number of other revenue streams, like rental income, retirement income, savings or investments, or other random income (i.e. - jury duty income, hobby income, or alimony payments, to name a few).
