The Roth IRA in Massachusetts

Massachusetts Roth IRA report card

Start with the action you are considering. These are the Massachusetts rules to check, with official sources for each.

New IRA contributions

Neither a Traditional nor a Roth IRA contribution produces a Massachusetts income-tax deduction. Federal treatment can differ. DOR contribution rules.

Traditional IRA conversions

Previously Massachusetts-taxed contributions may reduce the state-taxable amount. Keep contribution and prior-recovery records. DOR cost-recovery rule.

Ordinary conversion tax

The Massachusetts-taxable portion ordinarily faces 5% state tax. Calculate that portion before applying a rate. DOR tax rates.

The 2026 surtax

An additional 4% applies only above $1,107,750 of Massachusetts taxable income. The threshold is not federal AGI. DOR surtax rules.

Qualified Roth withdrawals

A federally qualified Roth IRA withdrawal is excluded from Massachusetts income, including the surtax base. DOR Roth treatment.

Moving

Nonresident Roth conversions are not taxed by Massachusetts, but actual residency—not a new mailing address—controls. DOR conversion guidance; residency tests.

Creditor claims

The individual-IRA exemption has contribution limits and specified court-order exceptions. It is not a promise against every claim. Massachusetts exemption statute.

Estate tax

An owner's Roth can enter the estate-tax calculation. Income-tax-free withdrawals and a beneficiary designation do not settle that calculation. DOR estate-tax guide.

First, which action are you taking?

A Roth IRA is a retirement account you own. To understand the tax treatment, separate three actions that can sound similar:

• Contribute: put new money into an IRA. A regular Roth contribution has eligibility and annual-limit rules. Massachusetts gives no deduction for either a personal Traditional IRA contribution or a Roth IRA contribution—even when the Traditional contribution is deductible federally.
• Convert: move existing eligible retirement money into a Roth IRA. This is not the same as making a regular annual contribution. A conversion can create current income even though the money remains in a retirement account; the taxable amount needs to be calculated.
• Withdraw: take money out. A qualified Roth IRA withdrawal is excluded from federal and Massachusetts income. That does not make the earlier conversion tax-free.

“Qualified” has a specific meaning. The applicable Roth five-tax-year period must be satisfied, along with a qualifying condition—commonly reaching age 59½. Death, disability and qualifying first-home treatment have their own rules. A withdrawal that is not qualified is not necessarily all taxable: federal ordering treats regular contributions first, conversion and rollover amounts next, and earnings last. Taxable earnings and any additional federal early-distribution tax are separate questions. IRS Publication 590-B explains those distinctions; DOR follows the federal Roth income exclusion.

One IRA, two different tax records

Basis is your record of amounts that can come back without being included in income again. It is not a second account or a particular investment inside the IRA. Massachusetts and the federal government can recognize different amounts because they treated your original contributions differently.

Your federal record tracks nondeductible Traditional IRA contributions and the basis you have already recovered, commonly through Form 8606. The federal calculation generally allocates that basis proportionally; it does not simply let you label a conversion “only my after-tax dollars.” Other Traditional, SEP and SIMPLE IRA balances can affect that calculation. IRS Form 8606 is the starting document to review.

Your Massachusetts record tracks contributions previously subject to Massachusetts tax and the recovery already used. Because the state denied the personal Traditional IRA deduction, a contribution deducted federally may still belong in this state history. Massachusetts generally lets that previously taxed amount come out first, before later IRA income is taxed. This is cumulative recovery, not a new allowance every January. DOR's cost-recovery directive and the current statute explain the distinction.

The 2025 Massachusetts Schedule X instructions use contribution and prior-distribution history. When both spouses receive the covered distributions on a joint return, they complete separate worksheets. A spouse's unused recovery is not a shared household pool. Keep old returns and contribution/distribution records with the account history; a custodian's current balance does not establish what Massachusetts taxed years ago.

A $50,000 conversion, explained dollar by dollar

Consider one owner who has always lived in Massachusetts and has one Traditional IRA worth $100,000 immediately before a hypothetical 2026 conversion. Its history is:

• $30,000 of contributions deducted federally but previously taxed by Massachusetts;
• $10,000 of federally nondeductible contributions, also previously taxed by Massachusetts; and
• $60,000 of investment growth.

Together, the contributions create $10,000 of federal basis and $40,000 still available for Massachusetts recovery. There have been no earlier distributions or conversions. The owner converts $50,000 and has $50,000 left in the Traditional IRA on December 31.

Assume no current contributions, other Traditional/SEP/SIMPLE IRA balances, other distributions, outstanding rollovers, qualified charitable distributions, special repayments or changes in value. No inherited account or public-pension rollover is involved. For the isolated Massachusetts tax result, the entire state-taxable increment is below the surtax threshold and deductions and credits do not change. Federal tax liability and benefit effects are not calculated.

The illustration uses the continuing mechanisms shown in IRS Form 8606 (2025) and the 2025 Massachusetts Schedule X worksheet. Both linked forms are for the 2025 tax year; the example is a hypothetical 2026 transaction.

The same $50,000 conversion creates $45,000 of federal taxable income but $10,000 of Massachusetts taxable income in this example. The federal calculation recovers $5,000 proportionally and leaves $5,000 of federal basis. Massachusetts recovers its full $40,000 first, leaving no state recovery amount from this history. The isolated Massachusetts tax is $500.

These are two calculations of the same transaction—not two deductions to stack. Subtracting $40,000 from the already reduced $45,000 federal amount would double-count part of the recovery. Likewise, the $500 is not the total federal-and-state cost. Different balances, prior withdrawals, new contributions or changing deductions require a fresh calculation from the records. The Massachusetts worksheet begins with total covered distributions, not simply the federal taxable figure.

The extra 4% is a layer, not the starting rate

Once you know the Massachusetts-taxable conversion amount, ask a second question: does it cross the surtax threshold? Ordinary conversion income generally faces the 5% state rate. For 2026, an additional 4% applies only to Massachusetts taxable income above $1,107,750—not to every dollar once the threshold is crossed.

The statutory surtax base adds the positive final taxable amounts in Massachusetts Parts A, B and C after their applicable deductions and exemptions. A negative final part does not reduce a positive one. This is not federal adjusted gross income, the account's balance or the gross conversion. Qualified Roth income already excluded from Massachusetts income stays out.

A joint return has one threshold, not one for each spouse. Separate IRA recovery worksheets do not change that. DOR's surtax guidance explains the filing rules and exceptions.

This is a different example from the basis illustration. Assume a full-year Massachusetts resident's 2026 surtax base is $1,087,750 before conversion. That means the final positive Massachusetts taxable-income parts—not federal AGI or gross receipts.

The conversion adds $50,000 of Massachusetts-taxable income after any state basis recovery. It is not merely a $50,000 gross transfer. Apply the published 2026 threshold of $1,107,750. There are no negative income parts or unused deductions, and the owner is not already above the threshold. Assume no changes in deductions, exemptions, capital-loss use, credits or benefits, and no other change to the income base. This isolates the ordinary state tax and additional surtax caused by the conversion. The DOR threshold and taxable-income definition govern the calculation below.

There is $20,000 of room below the threshold, so only the final $30,000 of this state-taxable increment attracts the additional 4%. Ordinary tax is $2,500; the added surtax is $1,200; together they are $3,700. Applying 9% to the entire $50,000 would instead produce $4,500—$800 more than this isolated calculation.

The lesson is to identify both the taxable amount and where it falls. A conversion entirely below the threshold and one entirely above it have different state-tax results. Neither example includes federal income tax or changing household tax benefits. Also, Massachusetts capital losses cannot offset ordinary conversion income just because a federal calculation permits an ordinary-income loss deduction. DOR's capital-loss rules keep those treatments separate.

Your employer plan is not your personal IRA

A personal Traditional IRA and a pre-tax workplace plan can start with different Massachusetts tax histories. For ordinary employees, qualifying pre-tax 401(k), 403(b) and governmental 457(b) deferrals generally stay out of Massachusetts income when excluded federally. Designated Roth deferrals are included currently. Compare that with the state deduction denied for a personal Traditional IRA contribution. DOR's contribution-treatment chart describes these employee-plan distinctions.

Moving pre-tax workplace money through a Traditional IRA does not create previously Massachusetts-taxed contributions. The 2025 Schedule X instructions specifically flag deferred-plan rollovers such as 401(k) money. Before assuming a state recovery amount, trace actual after-tax contributions and any historical state differences.

Government pensions need their own analysis. Massachusetts excludes Social Security and specified contributory government pensions, but retirement or public employment does not automatically exempt a personal IRA conversion or pre-tax TSP withdrawal. Other states' contributory pensions have a reciprocity rule; it is not a general IRA exemption. DOR's government-pension guidance distinguishes the payment types.

There is a narrow pension-to-IRA exception worth retaining: Directive 89-8 allowed recovery of a qualifying Massachusetts pre-retirement pension lump sum, including its pension interest, after rollover to an IRA with no further contributions. That is not a ruling that all later IRA earnings—or every direct pension-to-Roth transfer—are exempt.

Self-employed savers should also check the business form. Massachusetts disallows specified retirement-contribution deductions made on a partner's or sole proprietor's own behalf, including the elective and matching 401(k) contributions addressed by Directive 08-3. S-corporation shareholder-employees have different treatment. An ordinary employee's payroll result is not a reliable substitute for this separate analysis.

Moving changes the question—not your old records

A move changes the questions, not just the address on the IRA. Work through three issues separately: your residency, when the conversion is received, and the records that follow you.

Establish residency first. Massachusetts can treat you as resident because it remains your domicile—your true, fixed home—even without a minimum day count. An out-of-state domiciliary can also be resident by maintaining a Massachusetts permanent abode and spending more than 183 counted days here. Partial days count; exactly 183 does not satisfy that second test. A continuously maintained home, including one owned or leased by a spouse, can matter. DOR considers the actual move and intention to make the new place home, not one address change or registration. DOR's residency guide explains the factors and exceptions.

Match the conversion to the resident period. The 2025 Form 1-NR/PY instructions report Roth conversions received while a Massachusetts resident, including income from outside the state. Do not simply multiply an annual conversion by the fraction of the year lived here. Federal law protects qualifying nonresident IRA income, and DOR expressly says nonresidents are not taxed on Roth conversion distributions. A transaction spanning a move needs review of its actual dates; this is not a request-date or settlement-date shortcut. Continuing Massachusetts wages, property or business income can still require separate reporting.

Bring both contribution histories. Arriving in Massachusetts does not create extra state basis for contributions never taxed here. A returning resident may have earlier Massachusetts-taxed contributions to substantiate. Keep federal nondeductible basis separate; moving does not itself erase it, and overlapping amounts must not be deducted twice. The Massachusetts statute ties its additional recovery to previously Massachusetts-taxed amounts.

Qualifying military households have separate servicemember-and-spouse residency elections. Ordinary moving checklists do not replace those rules.

Saving through work in Massachusetts

Massachusetts has retirement programs that can offer Roth contributions, but the account type matters. CORE is a multiple-employer 401(k) sponsored by the State Treasurer. An eligible Massachusetts nonprofit with 100 employees or fewer can choose to adopt it; the size ceiling increased effective July 1, 2025. Employees participate through an adopting employer, rather than opening a personal Roth IRA through CORE.

CORE offers pretax and Roth choices. Its automatic-enrollment default is 6% pretax, with employer-selected annual increases of one or two percentage points up to 15%. Unless an employee chooses otherwise, enrollment occurs no sooner than 60 days after notice. Read the enrollment notice and make your own election: the default is not an automatic Roth contribution.

For eligible public employees, the Massachusetts SMART Plan offers voluntary pretax and Roth 457 salary deferrals. That is another workplace account, not a Roth IRA. The name “Roth” does not make every account's contribution limits and withdrawal rules identical, and an available Roth option does not by itself promise an employer match.

Secure Choice is separate. The FY2026 provisions were returned for amendment; H.4248's legislative history records a July 2025 committee referral. The 2026 economic-development bill containing a Secure Choice proposal shows conference appointments as its latest displayed action on September 8, 2026. Those records do not establish a launched program or current employer enrollment duties. CORE's enacted expansion should not be confused with those proposals.

College savings and the Roth connection

U.Fund is Massachusetts' 529 college-savings plan. U.Plan is a separate bond-based prepaid-tuition program that locks in a percentage of undergraduate tuition and mandatory fees at participating Massachusetts institutions. They share a state contribution deduction, but they are not interchangeable accounts. In particular, do not apply the 529-to-Roth transfer option to U.Plan.

Qualifying contributions share a combined annual Massachusetts income deduction of up to $1,000 for single, head-of-household and married-separate filers, or $2,000 for joint filers. This is one taxpayer limit across qualifying accounts and children. The December 31 owner of record is treated as the contributor. The deduction reduces taxable income; it is not a $1,000 or $2,000 reduction in the tax bill.

A qualifying 529 transfer directly to the beneficiary's Roth IRA is excluded from Massachusetts gross income beginning with tax year 2024, consistent with the federal exclusion. The federal conditions still matter: at least 15 years of account history, eligible contributions and associated earnings from before the final five-year period, sufficient compensation, coordination with that year's IRA contribution limit, and a $35,000 lifetime ceiling. Recent contributions and their earnings are not the eligible pool. This is not an unrestricted way to convert any education account into retirement savings.

There is a separate state question: whether an earlier Massachusetts education-contribution deduction must be repaid. The gross-income exclusion does not settle that issue. Confirm the treatment with DOR or your tax preparer before a transfer; this guide does not assume either automatic recapture or a blanket exemption from it.

Families starting earlier have two distinct opportunities. BabySteps supplies a $50 seed for an eligible Massachusetts child's U.Fund opened before the first birthday or first adoption anniversary, without a family match. NextSteps offers a one-time $50 match for qualifying first accounts opened from January 1, 2026 for children ages 1 through 3. NextSteps requires at least $50 from other sources before the account's first anniversary and excludes children who already received BabySteps.

The senior property-tax credit uses its own income rules

The latest schedule used here is for 2025, not a projection for 2026. It provides a maximum Senior Circuit Breaker credit of $2,820. The 2025 income ceilings are $75,000 for single filers, $94,000 for heads of household and $112,000 for joint filers. The homeowner assessed-value ceiling is $1,298,000 as of January 1, 2025.

Eligibility includes being at least 65 by year-end and occupying a qualifying Massachusetts principal residence, with additional conditions. Married-separate filers do not qualify. For homeowners, the calculation compares qualifying property tax plus half of separately charged water and sewer payments with 10% of adjusted total income. Renters use 25% of qualifying rent instead of those homeowner payments. The applicable maximum still limits the result.

For a conditional 2025 illustration, $8,000 of qualifying homeowner payments and $60,000 of adjusted total income leave $2,000 above the 10% income amount. At $70,000 of adjusted total income, the same payments leave $1,000. Assume all other requirements are met. These examples show the income sensitivity; they do not classify a Roth withdrawal or conversion.

Before counting on a credit, have the actual transaction reviewed under the applicable Schedule CB rules. This guide does not automatically include or exclude every Roth dollar. For a 2026 estimate, first obtain the 2026 indexed limits rather than reusing these 2025 amounts.

For health coverage, start with the program name

An account balance, a withdrawal and a conversion are different facts. For MAGI-based MassHealth pathways covering most children, pregnant people, parents and expansion adults, there is no asset test. A federally taxable conversion can nevertheless affect countable income. Massachusetts' additional IRA cost recovery does not, by itself, lower the federal taxable amount used for that analysis. Household composition, the month income is received and applicable exclusions matter; a conversion does not automatically mean coverage ends.

Regular community MassHealth Standard for people age 65 and older uses a different screen: generally income at or below 100% of the federal poverty level and countable assets of $2,000 individually or $3,000 for a couple living together. That is not the rule for every older applicant. A separate MAGI route for qualifying older parents or caretaker relatives with a child under 19 has no asset limit.

CommonHealth also provides a distinct route for some disabled adults age 65 and older. Qualifying working adults and certain nonworking adults with at least ten years of earlier CommonHealth coverage use separate financial rules, not the ordinary older-adult asset rules. Disability, work or coverage history and other conditions still apply, and premiums may be required.

Massachusetts Medicare Savings Programs have had no asset test since March 1, 2024. Their income limits and counting rules remain. Do not use an IRA balance alone as an asset-test barrier, or assume that no asset test means every distribution is excluded from income.

Long-term-care eligibility needs its own assessment. Massachusetts considers a couple's combined countable assets regardless of ownership. For 2026, the published community-spouse maximum standard is $162,660, but the allowance is not a universal half-assets calculation. The state uses the greatest of combined countable assets up to the indexed ceiling, a court-ordered amount, or an amount determined after a fair hearing. The reference entries include the additional dollar standards. Account treatment, assessment timing, income allowances and transfer rules require separate review before a transaction.

Finally, MassHealth estate recovery is not Massachusetts estate tax. For deaths from August 1, 2024, the age-55+ recovery category is narrowed to long-term-care-related services, with separate permanently institutionalized rules. Recovery is limited to the probate estate and remains subject to applicable protections. Whether a particular IRA actually passes outside probate depends on its arrangement.

What account protection does—and does not—cover

“Tax-free” and “protected from creditors” answer different questions. Massachusetts law exempts an individually maintained IRA from ordinary attachment and execution, subject to limits. Applying that IRA category to an owner's Roth is a reading of the statute alongside the federal Roth IRA definition; the Massachusetts section does not separately name Roth IRAs.

The exceptions matter. Specified divorce, separate-maintenance and child-support court orders can reach funds as the law permits. After a criminal conviction, a court can also order payment of a monetary penalty or victim restitution. These exceptions do not automatically entitle every claimant to the account.

A separate limitation looks at deposits during the five years before bankruptcy or entry of judgment. Deposits exceeding 7% of the individual's total income for that same period lose this exemption. That is not 7% of the IRA balance or an annual contribution limit. Rollovers and transfers generally do not count as new deposits for this test, but they do not erase a limitation that already applied. The parallel pension-protection statute contains the period and tracing rules.

Protection may also change when money leaves the account. In the 2024 ZipBy v. Parzych, a federal district court applying Massachusetts law allowed creditors to reach the retirement distributions at issue after withdrawal. The ruling distinguished certain protected annuities. Do not assume an ordinary cash withdrawal carries the account's exemption into every later use.

Bankruptcy has a separate framework. The aggregate federal cap for covered IRA exemptions is $1,711,975 per debtor for cases filed April 1, 2025 through March 31, 2028. Specified employer-plan rollover amounts and earnings are disregarded; SEP/SIMPLE accounts are outside this cap. Those exceptions do not mean every Roth conversion is uncapped. See the official adjustment notice and §522 rules.

An account kept as inherited also needs separate legal review: Clark v. Rameker rejected the federal retirement-funds exemption for inherited IRAs. That federal holding does not decide every Massachusetts state-law claim or an eligible spouse's rollover into an own IRA.

Tax-free withdrawals do not mean estate-tax-free

A qualified Roth withdrawal can be income-tax-free for a beneficiary while the owner's Roth balance is still included in an estate-tax calculation. Estate tax concerns the property transferred at death, not just taxable withdrawals. Naming a beneficiary can allow an IRA to pass outside probate, but nonprobate treatment is not an estate-tax exclusion or a blanket creditor exemption.

For current deaths, Massachusetts' principal filing test asks whether the gross estate plus adjusted taxable gifts exceeds $2 million. That is not a tax on the IRA alone, nor a promise that crossing the filing threshold creates tax due. Gifts can affect filing without being added to the state-death-tax-credit calculation. The current M-706 instructions explain the distinction.

The state uses a tax table and a credit of up to $99,600; it does not simply apply one flat rate to the amount over $2 million. The credit removes the former threshold cliff—a sudden tax jump from crossing the threshold. Deductions, estate composition and property location still affect the result. DOR's estate-tax guide walks through the calculation.

Rules effective for deaths on or after August 1, 2025 also matter for multistate estates. A resident's calculation excludes out-of-state real and tangible property and adjusts for qualifying Massachusetts-only marital-trust property, called QTIP. Associated deductions must follow the allowed property base. For nonresidents, the current liability calculation instead focuses on Massachusetts real and tangible property, rather than prorating a worldwide-estate tax. The worldwide estate-and-gifts filing test remains separate. An ordinary IRA interest is not real or tangible property merely because its custodian has a Massachusetts office. The current estate-tax statute sets these boundaries.

The executor generally handles the return and payment within nine months after death. A filing extension does not automatically extend payment. Massachusetts currently has an estate tax, not a beneficiary-class inheritance tax for a 2026 death, and no state gift tax. That does not remove gifts from the estate filing analysis. See DOR's transfer-tax guidance and the current M-706 instructions.

Plan how to pay the tax, too

Calculating conversion income and paying the resulting tax are separate steps. Withholding is a payment toward the bill, not a deduction that reduces the taxable conversion. Massachusetts withholding on eligible IRA payments generally follows the federal withholding election, with an exception for amounts not expected to be Massachusetts-taxable, including previously taxed contributions. Ask the payer how it handles the actual transaction and state recovery records; account interfaces are not all the same. The state withholding regulation explains the distinction.

The 2026 Circular M instructions permit Form M-4P or a payer substitute and additional withholding. A payer's calculation may not capture your other income or full surtax liability. Conversely, the mandatory federal withholding rule for an indirect workplace-plan rollover is not a rule for every IRA conversion.

For the ordinary estimated-tax safe harbor, the required annual payment is the lesser of 80% of current-year tax or 100% of qualifying prior-year tax. The prior-year alternative requires a filed return covering a full twelve-month tax year. Withholding counts, and current-year tax includes the surtax. This is a payment-timing rule, not a discount on the final liability. Massachusetts §14 supplies the conditions and special-case rules.

The general calendar-year 2026 installment dates are April 15, June 15, September 15 and January 15, 2027. If conversion income arrives late in the year, the annualized-income method may match required installments to that timing. It does not defer unrelated earlier tax, and paying everything when filing the return does not establish timely compliance. Review the 2026 Form 1-ES instructions alongside the timing of your income and withholding.

Which year do these rules cover?

This guide is dated September 8, 2026. Some 2026 amounts are already published, including the $1,107,750 surtax threshold and the regular IRA limit of $7,500, or $8,600 at age 50 or older. Regular IRA contributions share that annual limit; Traditional-to-Roth conversions do not use it as a conversion ceiling.

The annual Form 1, Form 1-NR/PY and Schedule X instructions cited here are labeled 2025. A later webpage update does not change their tax year. Published 2026 estimated-payment forms are separate from final annual-return instructions. Use the final forms for the year you are filing, and do not assume future line numbers or Circuit Breaker limits are unchanged.

How to use this guide and its examples

This guide provides general education, not a personal tax, legal or benefit-eligibility determination. A qualified Roth withdrawal can be excluded from income while the owner's account remains relevant to estate tax. A beneficiary arrangement can avoid probate without deciding creditor protection. And ending Massachusetts residency for an IRA conversion does not erase tax on continuing Massachusetts-source wages, business or property income.

Bring separate federal and Massachusetts IRA histories to your tax preparer, including each spouse's contributions, earlier distributions, rollovers and residency dates. For benefit or long-term-care questions, identify the specific coverage pathway and ask how the actual account and transaction will be treated. For creditor, inheritance or estate questions, have the account documents and relevant dates reviewed. Do not turn a general rule—or an unresolved classification—into an assumption about your balance.
