'Tis the season for filing taxes as a married couple. Newlyweds currently accessing their W-2s may be exploring the tax benefits of marriage, as well as the benefits of married filing jointly vs. separately. Admittedly, gathering your IRS forms and deciphering a new tax code may seem like one of the least appetizing ways to welcome life as newlyweds, especially if you just returned from a fabulous honeymoon and unpacked those registry gifts. But understanding the tax benefits of marriage (one of the many perks) *may* sweeten the deal. If you haven't already, it's time to roll up those sleeves yourself, hire a CPA (certified public accountant) or enlist a tax service to do the heavy lifting on your behalf. Filing taxes married may lead to questions about marriage tax brackets, maximum tax breaks and more. Here's how to navigate tax season as newlyweds.

Documents You Need for Filing Taxes After Marriage

Spring isn't only a time to welcome Daylight Savings. For US couples, it's also tax season: a period where you'll either have to crunch the numbers yourselves or hire a CPA or digital service to report your earnings for the previous year. While most will have experienced this separately, newlyweds will be facing a first when filing taxes married. It may lead to questions about marriage tax brackets, maximum tax breaks, whether to file jointly or separately, and more. Before you dig into the details, start by setting yourself up for success. In addition to gathering the basics like your Social Security numbers, birth dates, valid IDs and bank account numbers, here are some of the documents you need for filing taxes after marriage.

W-2 and/or 1099 Form

Lisa Greene-Lewis, a CPA and TurboTax spokesperson, says that each person must have either a W-2 or 1099 form to file taxes. The former is an official IRS document provided by employers that outlines an employee's annual earnings, taxes withheld and benefit contributions. A 1099, on the other hand, is a similar IRS form for contractors, freelancers or people who earn non-employee income or miscellaneous income. These documents are essential for filing taxes.

The Previous Year's Tax Returns

When you file taxes, you report your earnings for the previous year—but information from the year before that can be helpful to have on hand too. "When you get married, you'll want to have each of your previous tax returns," says Greene-Lewis. "You might need to refer to that and get information you'll need for the current year." Thus illustrates the importance of organizing all your essential documents, especially when you're newly married. Keep your information in one, easily-accessible spot, because you may never know if and when you'll need to refer to past years.

Additional Financial Documents

The exact collection of documents you need for filing taxes jointly or separately varies among couples. If you pay home mortgage interest, Greene-Lewis says, that information will be reported on a 1098 form. If you have student loans, that payment history will be listed on a 1098-T form. You may also need forms that itemize childcare records, charitable donations or medical expenses. An exact list of what you have to submit can be determined by a CPA or an online service.

Name and Address Changes

You may have also changed your name after marriage, in which case you must report this to the IRS (Internal Revenue Service). Discrepancies between your updated name and what the agency has on file could disrupt your tax return. The best way to notify the IRS is by updating your Social Security card. This also applies to a change of address, which requires that the US Postal Service be notified in forwarding of mail service (which can be done online) and by sending the IRS Form 8822, Change of Address.

The Best Time to File Taxes as a Married Couple

It's the golden question: When's the best time to file taxes? Taxes are always due on Tax Day, April 15, unless that date falls on the weekend (in which case they'll be due on the next business day.) Perhaps unsurprisingly, any expert will tell you it's best not to delay the process. The optimal timing for filing taxes (married or not) is sooner than later in the season. Prepping in advance will alleviate any pressure, especially if you need to work through the differences in filing jointly or separately.

"It's complicated and requires a little bit of attention beyond just saying, 'Okay, we've got to do our taxes and get started over the weekend,'" says Jeff Motske, president and CEO of Trilogy Financial Services and author of The Couple's Guide to Financial Compatibility. "Keep both an electronic file and a paper file and continue to look at them [and] put things in there, but don't wait until April. Open it up in [the New Year] when you start [receiving] important information [like your W-2 forms, for example]."

How to Determine Your Marriage Tax Bracket

It helps to know your marriage tax bracket, whatever that may be. You have two filing options after the wedding: jointly or separately. "Married filing jointly" tax brackets apply to your combined income, while "married filing separately" tax brackets apply to your individual income. Which you select depends on your specific circumstance, but more on that below. Knowing your bracket(s) helps you understand the rate at which you're both taxed. That can influence financial planning and make tax return surprises (such as owing extra money) less likely.

Experts suggest preparing the tax returns both ways to work through calculations. From there, couples can work through whether to file jointly or separately. Most services provide an automated option for couples to easily discover their best filing status.

Just as it's crucial to have money management conversations before getting married, this continues long after you exchange vows. Motske recommends scheduling a monthly financial date night so you're consistently on the same page. "If there's one thing I'd encourage all couples to do, it would be to be transparent about their money and determine what their budget is," he says. "Once they figure that out, they can figure out the tax aspect of it as well. Taxes need to be calculated into your budget too."

It's easy to find your married tax bracket. Use an online guide, like TurboTax's tax bracket calculator or H&R Block's tax bracket guide, to review the most recent federal tax brackets and understand how they work.

The Tax Benefits of Married Filing Jointly

The tax benefits of marriage depend on how you file. "Most [married couples] file together, and in most cases, filing jointly works better than filing separately. But everybody's scenario is case by case," Motske says. Married filing jointly basically means you're sharing tax liability, and in turn, submitting one tax return together. But what exactly are the tax benefits of marriage if you file together?

The Highest Standard Tax Deduction

First off, married couples filing jointly qualify for the highest standard tax deduction, which is $31,500 for most couples under age 65 in 2025 (up from $29,200 in 2024). According to TurboTax's guide to filing jointly or separately, they're often eligible for extra tax credits too.

Because of the way "married filing jointly" tax brackets are structured, you may get a "marriage bonus." If one spouse's income is more than the other's and they file jointly, the higher earner could potentially owe the government less than if they filed separately. Essentially, their partner's income may lower their tax bracket. Of course, it goes the other way too—that could increase the lower earner's tax rate. Do some math to determine what would happen in your specific situation.

Gift Taxes

One of the greatest benefits of filing jointly in marriage just happens to be a love language. Doing so allows one spouse to give the other unlimited gifts in cash or property, free of traditional gift taxes. It's worth noting this applies only to US citizens.

IRA Benefits

Here's another perk for couples who individually hit the annual contribution threshold for their IRA. While the limit is $7,000 per filing year, married couples filing jointly can each hit the limit, even with one income. In short, a married couple could contribute up to $14,000 across two IRAs. That number can increase to $16,000 ($8,000 per person) if they're over 50.

Estate Protection

Succession isn't the only place where you'll come across estate and gift tax exemptions. As couples talk through estate planning, there's an unlimited marital deduction that can help protect the estate in the case of death. Under federal law, one party can leave assets to the surviving spouse without being taxed.

Saving Time

This goes without saying, but filing taxes together as a married couple could save some time over, say, filing twice individually. Consulting with an expert, if necessary, can also ultimately save money and valuable time, especially if both parties tune into the nuances of ways to maximize their marriage tax benefits.

Higher Charitable Deductions

Opening those pocketbooks (both physical and digital) doesn't only help others. Donating cash can result in a deduction, allowing you to lower your taxable income.

The Tax Benefits of Married Filing Separately

Can married couples file taxes separately? The answer is yes. While most couples may benefit more from filing taxes together, there are some nuances to consider for married filing separately. "Married people that file separately tend both be high income earners, so they may be in a bracket where they've exceeded that benefit for their tax rate," says Greene-Lewis. You'll want to weigh the pros and cons of what works best for you within your respective brackets. These are just a few of the possible tax benefits of filing separately.

Avoiding Tax Liability

Did you know that if your spouse messes up a figure, you're equally liable for those numbers? "One benefit of filing separate tax returns would be tax liability—in other words, filing separately so you don't assume someone else's tax liability right away," Motske says. "So, if one of you has had some problems in the past, you might want to be careful. That's why transparency and understanding what goes on with your partner's finances is so important."

Avoiding the Marriage Tax Penalty

There's also the possibility of what's called a "marriage tax penalty." Infrequently, filing jointly can put you both in a higher tax bracket than if you filed separately. (This only happens if both spouses were originally in one of the higher tax brackets. It's also worth noting: the top tax rate is 37% for those with incomes beyond $626,350 for single filers and $751,600 for married couples filing jointly.) One of the reasons this takes place is because the married filing jointly (MFJ) income tax brackets aren't equal to twice the single income tax bracket.

Filing Due to Out-of-Pocket Medical Expenses

One occasion where married filing separately may benefit both parties if one person has a large number of medical expenses paid out-of-pocket. In these instances, that individual may be able to more easily qualify for medical deductions as it requires passing the 7.5% barrier of the adjusted gross income, as opposed to filing jointly.

When to Consult an Expert for Filing Taxes Married

If you still have questions about married filing jointly vs. separately, figuring out your 2025 marriage tax bracket, necessary documentation, or anything else pertaining to filing taxes as a newly married couple, hiring a pro to walk you through the process is worth it. There are even some tax hacks you might not know exist. (For example, Greene-Lewis notes that some wedding expenses can be written off in certain circumstances.) Working with a trusted pro can help you navigate all your options when you're filing taxes married.

"I always encourage people to see professionals. Just like you'd go to the doctor or dentist, the same goes when it comes to your finances and taxes. Especially after a big expense like a wedding, [newlyweds] are just burnt out financially by the time tax season comes around, and they're not quite ready to go back into that space," Motske says. "That's where a professional can come in and be unbiased and make the process as painless as possible. Seeing someone who's able to answer your questions, run your scenarios multiple different ways and know the tax codes better than software is so valuable."

That said, even online tax filing comes with personalized support. If you use TurboTax or H&R Block, for example, you can still request help from experts through live chats or one-on-one sessions that should be scheduled in advance. TurboTax even offers line-by-line tax return reviews with a CPA or EA.

How to Optimize Your Tax Refunds as a Married Couple

So you've gotten through tax season and you wound up with a refund. Now, you have to decide how to use it together. "I always advise people to put it to work for them," says Motske. "Make sure you're putting those tax savings somewhere meaningful, whether it's [saving up to] buy a house or pay off some debt." Greene-Lewis also suggests investing some of your refund into your IRA, as your contributions may be deductible in the next year's tax refund. Regardless of how you decide to use your tax refunds, allocating your money with intention and care is one massive leap toward financial wellbeing in your relationship.
