Form 1099-R box guide
Box 1: Gross distribution
Total amount paid before rollovers, exclusions, or basis recovery.
What this box tells you
Total amount paid before rollovers, exclusions, or basis recovery.
How to use it
Use it as the starting amount, not automatically as taxable income.
Where Box 1 flows on your return
Box 1 becomes the amount reported on Form 1040 Line 4a (IRA distributions) or Line 5a (pensions and annuities) — the "gross" line. It is not, by itself, your taxable income; the taxable portion goes on the paired Line 4b or 5b, using Box 2a or your own calculation.
How Box 1 works
Box 1 reports everything the payer sent out during the year before subtracting anything — federal withholding, state withholding, employee after-tax contributions, or amounts you rolled over. If you rolled part of the distribution directly into another IRA or plan, that rolled-over amount is still included in Box 1, and you back it out using the taxable-amount calculation, not by expecting a smaller Box 1.
Because Box 1 always shows the full amount, it commonly does not match your taxable income. A $50,000 IRA distribution where $20,000 was directly rolled to another IRA and $30,000 was kept still shows $50,000 in Box 1 — the taxable $30,000 shows up separately in Box 2a.
Worked example
Maria takes a $40,000 distribution from her traditional 401(k): $15,000 is directly rolled into an IRA and $25,000 is paid to her. Box 1 shows the full $40,000, and Box 2a shows $25,000 (the taxable portion, kept as cash). On her 1040, Line 5a shows $40,000 and Line 5b shows $25,000, with the Line 5c rollover box checked.
Put the boxes together
The taxable result depends on more than one field. Use the calculator to combine gross distribution, taxable amount, withholding, contributions, rollover, QCD, age, and distribution code.

Is Box 1 always taxable?
No. Box 1 is the gross amount before any rollover, after-tax basis, or exclusion is subtracted. Compare it with Box 2a (or calculate your own taxable amount) before assuming the full Box 1 figure is taxable income.
Why is Box 1 bigger than the amount I actually received?
If part of the distribution was withheld for federal or state tax, or was directly rolled to another account, Box 1 still shows the total before those subtractions — not just the check or deposit you personally received.
Where does Box 1 go on my tax return?
It flows to Form 1040 Line 4a for IRA distributions or Line 5a for pensions and annuities. The taxable amount (often different from Box 1) goes on the paired Line 4b or 5b.
