After years of preparing tax returns, accountants can tell you that tax season goes
smoothly for one simple reason: preparation. Every tax season, accountants see two
types of clients: those who walk in with a shoebox of crumpled receipts on April 14th,
and those who arrive in February with everything organized and labeled. Guess which
ones get better results and pay lower fees?
Here’s what accountants really need you to have ready before sitting down together.
Start by gathering all documents that show money coming in. Accountants need to see
every dollar that came into your household. Your W-2s should arrive by January 31st,
and returns can’t be filed without them. The same goes for 1099 forms: 1099-NEC for
contract work, 1099-INT for interest income, 1099-DIV for dividends, 1099-B for
investment sales, and 1099-R for retirement distributions.
Here’s something clients often miss: if you sold stocks, crypto, or real estate,
accountants need your purchase dates and costs, not just the sale information. Clients
have lost thousands in deductions simply because they couldn’t document their cost
basis.
Don’t forget the side income—jury duty pay, gambling winnings, prizes, unemployment
benefits, Social Security income, or rental property earnings. The IRS gets copies of
these forms too, and they notice when income goes unreported.
Tax professionals especially want to know about life events that happened in 2025:
marriage, divorce, births, adoptions, home purchases or sales, job changes, business
launches, inheritance, or significant medical events. These changes have substantial
tax implications and often require additional documentation and strategic planning.
Deduction Records: Where You Can Save Money
This is where accountants’ expertise makes the biggest difference, but only if you give
them the information they need. Accountants can’t deduct what they don’t know about.
You may qualify for new deductions available whether you itemize or not:
Income limits and eligibility rules apply, so bring documentation for any of these
categories.
The 2025 standard deductions are:
$31,500 for married filing jointly
$23,625 for head of household
$15,750 for single or married filing separately.
You only itemize if your total deductions exceed these amounts. If you’re itemizing, your
accountant will need the following:
statements. The state and local tax cap has increased to $40,000 for 2025.
gross income. While most people don’t reach this threshold, major surgeries,
chronic condition treatments, or significant dental work can get you there. Include
insurance premiums paid with after-tax dollars, mileage to medical appointments,
and prescriptions.
For donations over $250, we need written acknowledgment from the charity. If
you donated items to Goodwill or similar organizations, get a receipt and
document the fair market value.
If you paid tuition or student loan interest, gather Form 1098-T from educational
institutions and Form 1098-E for student loan interest. Records of 529 plan contributions
and withdrawals are also essential.
For families with young children, childcare expenses can qualify for valuable credits.
Accountants need the provider’s name, address, and tax ID number, along with the total
amount you paid.
Your Form 1095-A, B, or C documents health insurance coverage. If you received
advanced premium tax credits through the marketplace, Form 1095-A is essential for
reconciling what you received versus what you qualified for.
Traditional IRA contributions, HSA contributions, and SEP-IRA contributions can reduce
your taxable income. Bring statements showing these contributions.
Cryptocurrency is treated as property by the IRS. Every time you sell, trade, or use
crypto, it’s a taxable event. Accountants need records of every transaction: date, type,
amount, and value in USD at the time.
If you worked remotely for an out-of-state employer, you may need to file in multiple
states. Gig economy workers—Uber drivers, DoorDash deliverers, Airbnb hosts—need
documentation of all platform earnings and related expenses.
Start Early
Don’t wait until April. Gathering these documents takes time, and you may discover
you’re missing something that requires follow-up. Starting early gives you time to
request missing forms and have a less rushed conversation with your tax professional
about your tax situation.
Consider creating a year-round system where you file tax-related documents in one
location as you receive them. When tax season arrives, you’re already prepared.
The Bottom Line
Your accountant’s job is to maximize your legal deductions and credits while ensuring
accurate filing. Your job is to provide complete, organized documentation that makes
their work efficient and thorough. The better prepared you are, the more your
accountant can focus on strategic tax planning rather than hunting for missing
information.
By having these documents ready and organized, you’ll save time, reduce stress, and
potentially save money through deductions you might have otherwise overlooked. Your
accountant will appreciate your preparedness, and you’ll have confidence that your
return is complete and accurate.
