2024 Personal Income Taxes and What Taxpayers Need to Know

A 2024 tax return is due April 15, 2025, for most taxpayers, and the figures that shape the bill differ by filing status, income and the deductions or credits available. The most useful preparation step is to check the rules that fit your situation, from the standard deduction to retirement account limits, before choosing how to file.

2024 tax return rules: brackets, deductions and investment gains

For the 2024 tax year, federal income tax has seven marginal rates: 10%, 12%, 22%, 24%, 32%, 35% and 37%. A marginal rate applies to the portion of taxable income in its bracket, not to every dollar you earned. For example, moving into a higher bracket does not mean all your taxable income is taxed at that higher rate.

The thresholds below are for the return due in 2025. Filing status matters: married couples filing jointly and heads of household have different income bands from single filers. The figures are taxable income thresholds, so deductions generally reduce income before the brackets are applied.

The single filer figures shown for the 35% and 37% rates overlap: one threshold puts the 37% rate at $578,125, while the 35% band runs through $609,250. Do not use those conflicting numbers to calculate a return. Check the applicable IRS tax table or instructions for the precise threshold before filing. The other listed thresholds are arranged by filing status as shown.

Inflation adjustments raise many income thresholds from one year to the next, which can affect how much income falls into each bracket. They do not mean every taxpayer’s bill automatically falls. Income, deductions, credits and filing status all determine the result. Taxpayers comparing a 2024 return with an earlier year should use that year’s brackets and deduction amounts rather than assuming the old thresholds still apply.

Standard deduction or itemized deductions

The standard deduction reduces the amount of income subject to federal income tax. Most taxpayers can claim it without listing individual deductible expenses. The alternative is to itemize eligible deductions on Schedule A of Form 1040. Itemizing is generally worth comparing when the total eligible amount is larger than the standard deduction for your filing status.

To make the comparison, gather records for deductions you might claim, total the eligible expenses, then compare that figure with the amount in the table. Keep supporting documents even if the standard deduction wins. They can help you confirm whether a particular expense qualifies and give you a clear record of how you made the choice.

The Tax Cuts and Jobs Act of 2017 nearly doubled the standard deduction starting in 2018. The changes described here are scheduled to expire after 2025 unless Congress acts to extend them. That makes the 2024 figures useful for this return, but not a promise that the same amounts will apply to future tax years.

When itemizing could change the calculation

Several itemized deduction rules are especially relevant when comparing totals. The state and local tax deduction, often called SALT, is capped at $10,000 for the combined amount of state and local income taxes, property taxes and real estate taxes. If your eligible taxes exceed that cap, the excess does not increase this deduction.

For mortgage interest, the stated debt limit is $750,000, with a $1 million limit for a home bought before Dec. 16, 2017. The limit is not the same as a guaranteed deduction: eligibility and the amount of interest paid still matter. Use the lender’s annual records to work out the interest actually paid, then check which limit applies to the loan.

Cash gifts to eligible charities have a stated limit of 60% of adjusted gross income for 2024. The source rules also describe a possible total charitable deduction of up to 100% of adjusted gross income, and say the 60% limit is not automatic and must be elected on Form 1040. Donations to donor advised funds and supporting organizations do not qualify for that treatment. Because these limits depend on the type of gift and recipient, confirm the relevant IRS instructions before claiming a large contribution.

Medical expenses are deductible only to the extent that eligible expenses exceed 7.5% of adjusted gross income. That threshold means a filer with substantial medical bills may still have a smaller deductible amount, or none, after applying the calculation. Keep bills and payment records, and distinguish expenses you paid from amounts reimbursed by insurance.

Most miscellaneous itemized deductions are no longer allowed. The exception noted for this tax year concerns certain unreimbursed employee expenses. If you think that exception applies, confirm the rules for your specific work and expense rather than adding ordinary job costs to the itemized total.

Investment gains have their own rate schedule. Long term capital gains do not simply use the ordinary income tax brackets shown earlier. The table gives the 2024 thresholds by filing status, with the rate determined by taxable income and the relevant gain.

These figures are capital gains income thresholds, not a flat rate applied to every investment sale. Review transaction records and the holding period for each asset before working out the gain. If your return includes sales, do not assume the ordinary income bracket table gives the right rate for them.

Credits, retirement contributions and account withdrawals

For families and workers with lower or moderate incomes, credits can reduce the final tax bill or produce a refund. Their eligibility rules differ from deductions: a deduction reduces taxable income, while a credit reduces tax owed. Some credits are refundable, meaning a qualifying taxpayer can receive money even if the credit is greater than the tax liability.

The Child Tax Credit is $2,000 for each qualifying child. Up to $1,700 per qualifying child can be refundable for 2024. Confirm that each child meets the qualifying rules and retain the information needed to support the claim. The total credit and refundable portion are separate figures, so do not treat the entire $2,000 as automatically refundable.

The Earned Income Tax Credit, or EITC, is refundable and is aimed at eligible taxpayers with earned income. The maximum credit and the income limit depend on filing status and the number of qualifying dependents. The limits below show adjusted gross income caps for single filers and heads of household together, alongside the joint filing cap.

These are maximums and income limits, not a guarantee of the listed credit. Eligibility depends on the taxpayer’s circumstances and the credit rules. If you may qualify, use the IRS EITC tables or tax software that checks the credit rather than estimating it from income alone.

The Saver’s Credit, also called the retirement savings contributions credit, can reduce tax for people who contribute to an IRA, 401(k) or another eligible retirement account and meet the income rules. For 2024, the income limits are $76,500 for married couples filing jointly, $57,375 for heads of household, and $38,250 for single filers and married people filing separately. Check both the contribution and income requirements before claiming it.

Tax advantaged account limits are another place where records matter. The 2024 employee contribution limit is $23,000 for 401(k), 403(b), most 457 plans and the federal Thrift Savings Plan. Employees age 50 or older can make an additional $7,500 catch up contribution. SIMPLE retirement accounts have a $16,000 contribution limit and a $3,500 catch up limit for participants age 50 and older.

Traditional and Roth IRAs have a combined annual contribution limit of $7,000 for 2024, plus a $1,000 catch up contribution for people over age 50. The limit is not $7,000 for each account type. If you put money into both a traditional IRA and a Roth IRA, account for the total across the two.

Traditional IRA contributions may be deductible, but the deduction can be reduced or phased out when the taxpayer or spouse is covered by a workplace retirement plan. For a single taxpayer covered at work, the 2024 phase out range is $77,000 to $87,000. For a married couple filing jointly, it is $123,000 to $143,000 when the contributor is covered by a workplace plan. If the contributor is not covered but their spouse is, the range is $230,000 to $240,000.

A married person filing separately who is covered by a workplace plan has a $0 to $10,000 phase out range, which does not receive an annual cost of living adjustment. If neither spouse is covered by a workplace retirement plan, the phase out ranges described above do not apply. Check coverage for the tax year, not just whether you currently have a plan.

Roth IRA contributions are not deductible. Income limits apply to whether you can contribute: for 2024, the phase out range is $146,000 to $161,000 for single filers and heads of household, and $230,000 to $240,000 for married couples filing jointly. If income falls within a phase out range, the permitted contribution can be reduced. The source figures do not give the exact reduced amount for each income level, so use the IRS calculation rather than guessing.

Required minimum distributions returned for 2024. Under the age schedule described by the law, the starting age increased to 73 in 2023 and is scheduled to rise to 75 in 2033. The amount depends on factors that include the account value and life expectancy. Accounts covered by the requirement include traditional IRAs, SIMPLE IRAs, SEP IRAs and retirement plan accounts. A Roth IRA has no required minimum distribution during the original owner’s lifetime.

For anyone approaching the applicable age, check each account and determine whether a withdrawal is required for the year. Leaving money in a Roth IRA can allow it to remain invested for heirs, but that does not remove distribution rules that may apply to other retirement accounts. Do not assume that one account’s rules apply to every account you own.

The source materials also give limits for other benefit accounts, although the heading sometimes used for these figures can cause confusion. The $3,200 limit is for employee salary reductions to a health flexible spending account, or FSA. The deductible and out of pocket amounts below concern a medical savings account, or MSA, not an HSA contribution limit.

Check the type of account before using a limit. An FSA, MSA and HSA are distinct account arrangements, and the figures above do not establish an HSA contribution limit. Your plan documents and account provider can identify the account type and the rules that govern it.

Estate and gift tax thresholds may matter to families transferring assets. The basic estate tax exemption is $13.61 million for the estate of a person who died during 2024. The annual gift exclusion is $18,000 for 2024. These are separate thresholds: one concerns an estate, while the other applies to annual gifts. Keep records of transfers and check the applicable filing requirements rather than treating the exclusion as a blanket rule for all gifts.

Filing deadline, extension and choosing how to prepare

April 15, 2025, is the filing deadline for most 2024 individual federal income tax returns. Taxpayers can request an automatic six month extension by filing Form 4868, the Application for Automatic Extension of Time to File U.S. Individual Income Tax Return. The extension changes the filing timetable; follow the form instructions and IRS guidance for the steps that apply to your situation.

Some people affected by major storms or other disasters may qualify for a deadline extension announced by the IRS. Relief depends on the event and the taxpayer’s location or circumstances. Check the IRS disaster relief announcements rather than assuming an extension applies everywhere.

Before starting a return, collect income statements, records of retirement contributions, charitable donation receipts, medical expense documents and investment sale details. Then confirm your filing status and identify any dependents. This preparation makes it easier to compare the standard deduction with itemizing and to spot credits or retirement account rules that need extra attention.

Choosing between tax software and a paid preparer depends on both the return’s complexity and the filer’s time and confidence. Software is generally less expensive than hiring a tax professional, and it can guide people through common income and deduction questions. A straightforward return may be manageable without paid help, provided you can enter the figures accurately and understand the questions being asked.

A professional may be a better fit when the return includes a business, a major life event or itemized deductions. Those situations can involve records and choices that take more time to evaluate. A preparer’s fee is a cost to weigh against the possibility that specialist help identifies tax treatment or deductions the filer might otherwise miss. The possibility of a better result is not a guarantee.

Tax software and professional services are not interchangeable in every case. Software can reduce data entry errors through prompts, but it depends on accurate answers and complete records. A preparer can discuss complicated facts, but the taxpayer still needs to provide reliable documents and review the finished return. If a return is difficult to explain in a few sentences, that is a practical signal to assess the value of professional assistance.

The IRS adjusts many brackets and tax provisions annually to reflect inflation. More than 60 provisions are adjusted in a typical year, though some remain unchanged. The Lifetime Learning Credit, for example, had not been adjusted since 2020 according to the source material. Inflation adjustments should therefore be checked item by item rather than assumed to apply to every credit or deduction.

For this filing, the practical sequence is straightforward: establish the correct filing status, compare the standard deduction with eligible itemized amounts, check credits and retirement contribution records, then confirm the filing deadline or any disaster related relief. Use the 2024 limits for this return, and consult the IRS for any point where a listed threshold appears inconsistent or your personal circumstances require a more specific calculation.
