Introduction
Earning interest or dividends doesn't mean you follow the federal Schedule B rules when you file in Massachusetts. The state has its own Schedule B, its own triggers, and its own classifications. Many filers skip it because they didn't need the federal one, then find out otherwise.
This guide covers what Massachusetts Schedule B is, who needs it, which interest and dividend amounts belong on it, when you can skip it, and how to file it accurately. It is based on the 2025 Massachusetts Department of Revenue (DOR) instructions, so check line numbers again for later tax years.
Key Takeaways
- Massachusetts Schedule B is a state schedule, not a copy of the federal form.
- State filing triggers differ from federal ones, so don't rely on a federal threshold.
- Gather Forms 1099-INT and 1099-DIV, brokerage statements and carryover records first.
- Treasury, Massachusetts, other-state municipal and fund income are treated differently.
What Is Massachusetts Schedule B and What Does It Report?
What the schedule is used for
The official title is Schedule B: Interest, Dividends and Certain Capital Gains and Losses. Part 1 covers interest and dividends. Part 3 calculates taxable interest, dividends and certain gains. It attaches to Form 1 for residents and Form 1-NR/PY for nonresidents and part-year residents.
How it differs from federal Schedule B
The federal form, Schedule B (Form 1040), is a different document under IRS instructions. Massachusetts line 2 even accommodates taxpayers who never filed the federal schedule. So you may need the state schedule without the federal one.
The state form also picks up certain capital gains and Massachusetts adjustments. Foreign-account reporting (FBAR/FinCEN Form 114 and Form 8938) is a separate federal obligation and isn't part of it.
How it affects the return
- Line 38 (interest and dividends) carries to Form 1, line 20, or Form 1-NR/PY, line 24.
- Line 39 (taxable 8.5% and 12% capital gains) carries to Form 1, line 23a, or Form 1-NR/PY, line 27a, when Part 2, line 11 is blank. Otherwise the Taxable Capital Gains Worksheet applies.
Line numbers can change each year, so confirm them against the current Form 1 and Form 1-NR/PY instructions.
Who Needs to File Massachusetts Schedule B?
Common triggers
The 2025 Form 1 instructions say you must file Schedule B if you had any of these:
- Dividend income
- Interest income other than from Massachusetts banks taxed at 5.0%
- Short-term capital gains or losses
- Short-term loss carryovers from prior years
- Long-term gains on collectibles and pre-1996 installment sales
- Gains or losses from selling or converting business property
- Net long-term capital gains and losses
- Excess exemptions
One source conflict is worth knowing. DOR's general dividends webpage says Massachusetts follows federal filing requirements for dividends. The 2025 booklet lists dividend income outright as a trigger, with no federal threshold. Follow the booklet.
Residency and return type
| Filer | What gets reported |
|---|---|
| Full-year resident | Income received while resident, from inside or outside Massachusetts, subject to exclusions |
| Part-year resident | Resident-period income from all sources, plus Massachusetts-source income while a nonresident; line 6b removes non-Massachusetts-source amounts from the other period |
| Nonresident | Interest and dividends only when connected to Massachusetts business activity or Massachusetts real estate or tangible property |
For nonresident and part-year capital transactions, the instructions apply sourcing adjustments through Schedule B lines 13b and 19b. Not every federally reported transaction is Massachusetts-taxable. A foreign investor holding only U.S.-source income, with no Massachusetts business or property link, isn't taxed on it by Massachusetts for that reason alone.
When it may not be required
If all your interest comes from Massachusetts banks and none of the other triggers applies, you can skip Schedule B. Allowable deductions from a trade or business also defeat the exception. Report that bank interest on Form 1, line 5, or Form 1-NR/PY, line 7.
Don't assume a small amount, a missing 1099 or no federal Schedule B removes your obligation. The listed triggers control.
What Interest and Dividend Income Goes on It?
Classifying interest income
| Income type | Massachusetts treatment |
|---|---|
| U.S. Treasury and other U.S. obligations | Exempt; removed on line 6a (see TIR 89-8) |
| Massachusetts obligations | Excluded on line 6a |
| Other-state municipal bonds | Reported on line 3 if not already in line 1 |
Federal or other-state treatment doesn't control. Don't count other-state municipal interest twice: line 3 warns against repeating exempt interest already in line 1.
Classifying dividends and fund distributions
- Ordinary and qualified dividends: Line 2 uses total ordinary dividends from the federal return. Qualified dividends sit inside that total, and there's no separate state line.
- Fund ordinary distributions: Add to line 3 only if absent from lines 1-2.
- Exempt fund portion: Line 6a removes only the part derived from U.S. government or Massachusetts obligations, not the whole distribution.
- Capital gain distributions: Mutual fund and REIT distributions go to Massachusetts Schedule D, not line 2.
- Return of capital: Line 6a excludes it if it was included in line 2.
Lines 5 and 6 only remove amounts already included in lines 1-3. They aren't extra exclusions.
Reconciling records and missing forms
Schedule B starts from the total interest and ordinary dividends on your federal return, not a payer-by-payer 1099 list. Reconcile every 1099-INT and 1099-DIV against year-end brokerage statements before relying on those totals.
The instructions don't give a Massachusetts-specific procedure for missing 1099s, nominee amounts or corrected forms. Report all taxable income regardless, and amend if a corrected form changes your return.
How to Complete and File It
Gather records
- The applicable Massachusetts return
- Forms 1099-INT and 1099-DIV, including corrections
- Brokerage and mutual fund statements showing U.S. and municipal obligations
- Prior-year loss carryover records
Separate federal totals from Massachusetts adjustments before entering anything.
Enter income and calculate
- Line 1: total interest from federal Form 1040, lines 2a plus 2b.
- Line 2: total ordinary dividends from federal Schedule B, Part II, line 6, or Form 1040, line 3b.
- Line 3: other-state and other interest, with amounts and sources, plus a statement if needed.
- Line 4: total of lines 1-3.
- Line 5: remove separately reported Massachusetts bank interest.
- Line 6a: remove eligible exclusions, with a statement. Part-year and nonresident filers use line 6b.
- Line 8 and Part 3: apply business deductions, losses and excess exemptions (line 36).
Note that lines 1 and 2 are totals, not federal-style payer lists.
For example, one taxpayer has bank interest, Treasury interest, stock dividends and an out-of-state municipal bond. All interest and dividends flow in through the federal totals.
Treasury interest comes out on line 6a. Municipal interest is added on line 3 if the federal totals missed it. Massachusetts bank interest comes out on line 5 and goes to its own return line. Confirm each treatment against current DOR guidance.
Attach, file and keep records
Attach Schedule B to Form 1 or Form 1-NR/PY. Tax software may generate it automatically, but check payer details, totals, adjustments, residency and carryovers yourself.
- Deadline for 2025 returns: April 15, 2026, which is also the payment deadline.
- Extension: generally six months, to October 15, 2026, if at least 80% of total tax is paid by April 15. Interest runs on any unpaid balance.
- E-file: through MassTaxConnect or DOR-approved vendors. Approval isn't an endorsement.
- Paper filing: a complete, signed return with all pages. No staples or paper clips. Both spouses sign a joint return.
- Records: keep them generally at least three years after the later of the due date or filing date.
Common Errors, Documentation, and When to Get Help
Errors to check before filing
- Applying the federal Schedule B threshold to Massachusetts
- Treating all municipal interest as exempt
- Leaving out income because no 1099 arrived
- Subtracting amounts never entered in lines 1-3
- Claiming the Massachusetts bank-interest deduction, which was repealed effective January 1, 2024
Before you file, confirm:
- Payer names and any duplicate or corrected 1099s
- Fund exempt portions and carryovers
- Residency status
- Agreement between Schedule B and the main return
Filing before all statements arrive can force an amended return. Use a revised Form 1 or 1-NR/PY with all original schedules. Don't use an amendment to dispute an audit.
Records and professional help
Keep statements explaining state adjustments, especially where a brokerage statement doesn't separate federal and Massachusetts amounts. Professional help makes sense when you have:
- Multiple accounts
- Nonresident or part-year filing
- Foreign investments or business gains
- Amended returns or unclear adjustments

Frequently Asked Questions
What is Massachusetts Schedule B?
It's the state schedule for Interest, Dividends and Certain Capital Gains and Losses. It is separate from federal Schedule B.
Who needs to fill out Schedule B?
Anyone with a listed trigger: dividends, non-Massachusetts-bank interest, short-term or certain long-term gains or losses, carryovers or excess exemptions. See the current Form 1 instructions.
Is Massachusetts Schedule B the same as federal Schedule B?
No. They serve different tax systems with different triggers, classifications and state adjustments.
Do I need Massachusetts Schedule B if I only received interest from a Massachusetts bank?
Not if no other trigger applies. Report that interest on its separate return line. The exception doesn't exclude the income.
What documents do I need to complete Massachusetts Schedule B?
Forms 1099-INT and 1099-DIV, brokerage and mutual fund statements, corrected forms, prior-year returns, and carryover and residency records.
Can tax software prepare Massachusetts Schedule B automatically?
Often, from the information you enter. You still need to verify exclusions, totals and filing requirements, since vendor approval doesn't confirm support for every situation.
