Knowing how to prepare your personal taxes before your appointment can make the filing process more efficient and help you identify information that may still be missing. A complete tax file includes more than Forms W-2 and 1099. In addition, personal information, dependents, potential deductions, credits and tax payments can affect your return.
Therefore, begin by gathering the records that apply to your situation. Next, compare those documents with the income sources and financial changes you had during the year.
Most importantly, do not use a generic checklist as proof that a deduction or credit applies to you. Instead, use it to organize the information your tax preparer needs to evaluate your individual return.
BEFORE YOUR APPOINTMENT
Build a Complete Personal Tax File
A tax return brings together information from many different sources. Consequently, preparing only your income forms may leave important pieces missing.
First, create one folder for the tax year. A physical folder works, although a secure digital folder can also make documents easier to organize.
Next, group records by purpose: personal information, income, dependents, deductions and credits, tax payments and special financial events.
As a result, you get a clearer picture of what you have before the return is prepared. In addition, this system makes missing information easier to identify.
THE GOAL
Complete. Organized. Accurate.
Your tax documents tell different parts of the same financial story.
Therefore, bring those pieces together before the return is prepared.
CHECKLIST 01
Personal and Identification Information
Begin with the information used to identify you, your spouse and anyone else included on the return.
Even small errors in this section can create unnecessary filing problems.
Gather Identification Numbers
Have the Social Security number or applicable Individual Taxpayer Identification Number for yourself, your spouse and dependents included on the return.
Additionally, verify the spelling of each name. If you legally changed your name, make sure the appropriate records reflect that change.
Confirm Your Address
Use your current mailing address. If you moved during the year, tell your preparer because a move can also affect state filing requirements.
Have Your Current IP PIN
If the IRS assigned you, your spouse or an applicable dependent an Identity Protection PIN, have the current IP PIN available. Because a new IP PIN is generated each year, do not rely on an old number.
CHECKLIST 02
Gather Income Documents From Every Source
Your personal tax return can include several types of income. Therefore, compare the tax documents you receive with the jobs, accounts and financial activities you had during the year.
Employment and Retirement Income
Employees commonly receive Form W-2. However, if you worked for multiple employers, account for each job before filing.
Meanwhile, retirement income can generate forms such as Form 1099-R. Social Security recipients can also receive Form SSA-1099.
Rather than assuming last year’s income sources are identical, review what actually happened during the current tax year.
Interest, Investments and Other Income
Banks and brokers can issue Forms 1099-INT and 1099-DIV for interest and dividends. Other forms, meanwhile, can report unemployment compensation, miscellaneous income and payment transactions.
In addition, keep records of digital asset transactions and other reportable income even when you do not receive an information form.
Consequently, compare tax documents with your own records instead of treating the forms as the only possible sources of income.
CHECKLIST 03
Review Dependents and Family Changes
Family information can affect filing status, dependency claims and eligibility for several tax benefits. Therefore, tell your preparer about significant changes instead of simply copying information from the prior-year return.
For each potential dependent, gather the correct name and taxpayer identification number. In addition, be prepared to discuss the person’s relationship to you, age, residency and support when those facts are relevant.
During the year, marriage, divorce, birth, adoption and changes in custody or living arrangements can also affect the return.
For example, when more than one person might try to claim the same child, federal dependency and credit rules determine who is eligible. A family agreement alone does not necessarily override those requirements.
As a result, discuss unusual dependent situations before the return is filed.
FAMILY CHECK
Tell Your Preparer About
✓ Marriage or divorce
✓ Birth or adoption
✓ New dependents
✓ Changes in custody
✓ A child who moved out
✓ College attendance
✓ Changes in dependent income
Together, these facts can affect more than one part of the return.
CHECKLIST 04
Collect Records for Potential Deductions
A deduction generally reduces taxable income, but not every personal expense qualifies.
Therefore, organize potentially relevant records and allow the applicable tax rules to determine what can be claimed.
Standard Deduction or Itemized Deductions
Many taxpayers use the standard deduction. Alternatively, others may benefit from itemizing qualifying expenses on Schedule A.
For example, potential itemized deductions can include certain mortgage interest, state and local taxes, charitable contributions and qualifying medical expenses. However, each category has its own requirements and limitations.
Other Deductions
Some deductions do not depend on itemizing. For example, eligible taxpayers may have adjustments involving certain IRA contributions or student loan interest.
In addition, current federal law includes other deductions with specific eligibility requirements. Consequently, provide your preparer with relevant records even when you are unsure whether a particular tax benefit applies.
CHECKLIST 05
Gather Information for Potential Tax Credits
Tax credits and deductions work differently. Generally, a deduction reduces taxable income, while a credit reduces tax according to the rules for that credit. In addition, some credits can be refundable.
Children and Dependent Care
Families should organize information about qualifying children and other dependents. In addition, childcare expenses can be relevant when determining eligibility for the Child and Dependent Care Credit.
Therefore, keep the provider information and payment records that apply to your situation.
Before filing, families claiming child-related tax benefits should also make sure names and identification numbers are accurate.
Education and Other Credits
College students and families may receive Form 1098-T and have records of qualified education expenses. However, the form alone does not determine the amount of an education credit.
Meanwhile, Marketplace health insurance can generate Form 1095-A, which can be important for reconciling advance Premium Tax Credit payments.
Therefore, include these records in your tax file instead of waiting for your preparer to request them later.
CHECKLIST 06
Homeowners: Gather Property Records
Owning a home can create several records that are useful during personal tax preparation.
However, homeownership does not automatically make every housing expense deductible.
Mortgage and Property Tax Records
First, gather Form 1098 and records showing applicable real property taxes. These amounts can be relevant when determining itemized deductions, subject to federal limitations and other requirements.
Did You Buy, Refinance or Sell?
If you purchased, refinanced or sold real estate during the year, bring the applicable closing documents. A sale, for example, can require additional information involving selling price, adjusted basis, improvements and selling expenses.
In addition, keep long-term records of qualifying capital improvements. Those records may become important when the property is eventually sold.
CHECKLIST 07
Include Side Jobs and Self-Employment
A personal tax return can also include business activity. For example, freelance work, independent contracting and certain gig economy activity may be reported on Schedule C when the taxpayer operates as a sole proprietor.
However, do not prepare this section using Forms 1099 alone. Instead, gather complete records of business income and expenses.
Useful documents can include invoices, bank records, payment processor statements, receipts, mileage records and estimated tax payment information.
In addition, separate personal expenses from business costs. Mixed-use expenses may require allocation under the applicable rules.
Finally, consistent bookkeeping makes it easier to determine the business activity that belongs on your individual return.
SELF-EMPLOYMENT FILE
Bring More Than 1099s
✓ Business income records
✓ Forms 1099 received
✓ Expense records
✓ Receipts and invoices
✓ Mileage records when applicable
✓ Estimated tax payments
✓ Bookkeeping reports
Together, these records should reflect the complete business activity.
CHECKLIST 08
Review Investments and Digital Assets
Investment activity can require more information than the amount deposited into your bank account.
Therefore, gather annual tax statements and transaction information before preparing the return.
Stocks and Other Investments
Investment sales can require information about proceeds and cost basis to determine gain or loss. Although broker statements may provide much of this information, additional records can sometimes be necessary.
Also, gather Forms 1099-INT and 1099-DIV for applicable interest and dividend income.
Digital Assets
Likewise, keep records of cryptocurrency and other digital asset transactions. Taxable activity can exist even when no tax information form arrives.
Consequently, retain transaction histories showing relevant purchases, sales, exchanges and other activity needed to determine the federal tax treatment.
CHECKLIST 09
Account for Taxes You Already Paid
Your return does not only calculate income, deductions and credits. It also reconciles certain tax payments already made during the year.
Federal Income Tax Withholding
Forms W-2 and certain Forms 1099 can report federal income tax withheld during the year.
Because withholding affects the final balance or refund calculation, review these amounts carefully.
Additionally, if you worked multiple jobs, include the forms from each employer rather than assuming the information is combined automatically.
Estimated Tax Payments
If you made federal or California estimated tax payments, gather a record of the dates and amounts paid.
In addition, include payments made through an online tax account or with estimated tax vouchers.
Rather than estimating these amounts from memory, verify your payment records so the return reflects the payments actually made.
CHECKLIST 10
Verify Your Bank Information
If you choose direct deposit for a refund, gather the correct routing and account numbers before filing.
Likewise, verify banking information used for an electronic tax payment.
Check Every Digit
First, confirm that the account shown on an old return is still correct. Then, verify the routing number, account number and account type with your financial institution when necessary.
Review Where Your Refund Is Going
Before authorizing the return, review the direct-deposit information shown on it. Most importantly, you should understand where the refund will be deposited.
As a result, banking information deserves the same final review as your name, income and dependents.
ONE MORE STEP
Compare This Year With Your Prior Tax Return
Your previous tax return can be a useful reference because it shows income sources, dependents, deductions and credits that applied in the prior year.
However, do not copy it mechanically. Instead, use the prior return to identify what changed.
For example, you may have changed employers, started a business, sold investments, bought a home or had a child. Alternatively, you may have retired, begun receiving Social Security benefits or added a second source of income.
Because these changes can affect different parts of your current return, make a short list of significant differences and discuss them with your tax preparer.
Also, bring a copy of the prior return when your preparer does not already have access to it. This information can provide useful background and help identify items that deserve additional review.
ASK WHAT CHANGED
Compare With Last Year
✓ Employment
✓ Income sources
✓ Marriage or divorce
✓ Dependents
✓ Homeownership
✓ Investments
✓ Self-employment
✓ Retirement
Ultimately, your current return should reflect your current facts.
BEFORE YOU FILE
Make Sure Your Tax File Is Complete
Filing early can be useful. However, filing before you have necessary information can create additional work.
Therefore, check your expected tax documents before authorizing the return.
Don’t Ignore a Missing Form
If you know an employer, bank, broker or another payer should provide a tax form and it has not arrived, investigate before filing.
Similarly, if a form appears incorrect, contact the issuer when appropriate instead of simply leaving the information off your return.
Review the Completed Return
Finally, review your return before it is submitted. Confirm personal information, income, dependents, major deductions and credits, refund or balance due, and banking information.
Even when a professional prepares the return, the taxpayer remains responsible for the information reported on it.
AFTER FILING
Use This Year’s Return to Prepare for Next Year
Personal tax preparation should not end when the return is accepted. Instead, use the completed return to identify changes that may improve next year’s tax planning and recordkeeping.
Review Your Withholding
Federal income tax generally works on a pay-as-you-go basis. Employees usually make payments through paycheck withholding, while taxpayers without sufficient withholding may need estimated tax payments.
Therefore, review withholding after major changes in income or family circumstances.
For additional help, the IRS Tax Withholding Estimator can help eligible taxpayers evaluate federal withholding from jobs, pensions or annuities.
Keep Next Year’s Records Together
After filing, create a new tax folder and add relevant records throughout the year.
For example, save important property documents, charitable contribution records, estimated tax payments and business information when the transactions occur.
Consequently, next year’s tax preparation begins with organized records rather than a search through twelve months of paperwork.

COMMON QUESTIONS
FAQ About Preparing Personal Taxes
Finally, these answers cover common questions about getting an individual income tax return ready for preparation.
Your exact documents depend on your situation. Generally, common items include Forms W-2 and 1099, identification information, dependent records, documents for deductions and credits, estimated tax payment records and verified banking information. In addition, self-employed taxpayers should gather complete business income and expense records.
Your previous return can provide useful background and help identify changes. However, it should not simply be copied because income, dependents, deductions, credits and other circumstances can change from one year to the next.
If you know an important tax document is still expected, investigate before filing. Generally, preparing a complete and accurate return reduces the risk of having to address missing information after submission.
The absence of a Form 1099 does not automatically make business or freelance income nonreportable. Therefore, use your own records to determine the complete income and expenses from the activity.
If the IRS assigned you an IP PIN, use the applicable current IP PIN when filing a federal individual income tax return. Because the IRS generates a new IP PIN each year, an old number should not be reused as the current PIN.
Yes. Before authorizing filing, review personal information, income, dependents, significant deductions and credits, banking information and the final refund or balance due. In addition, ask questions when something on the return is unclear.
