April 15 is close enough that the decisions you make this week either put money in your pocket or leave it on the table.

Schedule 1-A is the new deduction block created by the One Big Beautiful Bill. It covers four separate items: no tax on qualified tips, no tax on the overtime premium, car loan interest up to $10,000, and a $6,000 senior deduction for filers 65 and older. Plus the SALT cap jumped to $40,000 this year. Each one requires data you either have organized or you don’t.

Most filers aren’t missing the deductions because of bad tax software. They’re missing them because the numbers never got tracked. Tip income recorded on crumpled receipts, overtime buried inside a single paycheck total, car loan interest split across twelve months of statements.

The right finance apps fix that problem before tax season. Here’s what actually works.

Skip if: Your W-2 already has Box 12 TP and TT codes and you’re not itemizing. Tax software handles the rest. Use if: You have tip income, hourly overtime, a car loan, or SALT-eligible property taxes that need to be tallied before you file.

What Schedule 1-A Actually Requires From You

Before picking an app, know what data each deduction needs.

No tax on tips. You need the total amount of qualified tips you received through employer payroll in 2025. If Box 12 code TP is on your W-2, you’re done. If it’s not (and most aren’t yet), you need your tip income from Box 7 or reconstructed from pay stubs. Apps that let you tag income by type can build this number over time instead of scrambling for it now.

No tax on overtime. The deduction covers the premium only: the extra pay above your base rate. On a $22/hour base, the $11/hour premium is deductible, not the full $33 OT rate. Knowing your total OT hours and rates is required. Payroll apps and income trackers can separate this from regular wages automatically if you’ve been using them.

Car loan interest up to $10,000. Every interest payment on a personal vehicle loan made in 2025 is potentially deductible. Twelve months of loan statements. If your loan servicer reports interest on a year-end statement, that’s enough. If not, you’re adding up individual payment breakdowns.

$6,000 senior deduction. Automatic if you’re 65+, no tracking required. But if your MAGI is near $150,000 (single) or $300,000 (joint), the phase-out means tip and overtime deductions that lower your MAGI might protect this deduction. Worth knowing.

SALT up to $40,000. State and local taxes: income taxes withheld, property taxes paid. If you itemize, the cap increased dramatically from $10,000. Property tax receipts and state withholding from your W-2 make this straightforward.

Copilot Money: Best for Tip Workers

If you earn tips, Copilot Money is the most practical app for Schedule 1-A prep.

Copilot’s income tracking lets you tag each paycheck with categories. For tip workers (servers, bartenders, delivery drivers, hair stylists), this means separating tip income from base wages across every deposit. Once set up, it gives you a running year-to-date total you can hand directly to your tax software.

The categorization is automatic but correctable. Copilot reads your bank and payroll deposits, guesses the category, and learns from corrections. If your employer runs tips through payroll separately from base pay (common with restaurant payroll systems), Copilot picks this up and tracks both lines.

For SALT, Copilot’s spending reports make it easy to pull your state income tax withholding history and property tax payments. Filter by payee and date range, export the total. Takes about five minutes.

Who it’s for: Hourly tip workers who want year-round tracking instead of a March scramble. Also useful for W-2 employees with multiple income sources.

Limitation: No direct tax integration. You’re exporting totals to use in your tax software, not filing from Copilot. For a deeper look at how it compares to Monarch for general budgeting, see the Copilot Money vs Monarch Money comparison.

Cost: $13/month. No free tier.

Security: Plaid-based bank connections (read-only). Data encrypted at rest and in transit.

Monarch Money: Best for Car Loan Interest and Full Deduction View

Monarch Money has the best loan tracking of any budgeting app right now.

For car loan interest specifically: Monarch connects directly to most auto loan servicers and tracks your balance, payment history, and interest paid automatically. You can pull the exact interest amount for 2025 in about thirty seconds. That number goes directly into your Schedule 1-A calculation for the car loan interest deduction (up to $10,000 for personal vehicle loans).

The net worth dashboard gives you a complete picture of your financial position, which is useful if you’re close to the MAGI phase-out thresholds for the senior deduction or overtime deduction. Monarch shows your income, balances, and deductions in one place. The “will this tip deduction help protect my senior deduction?” math becomes visible rather than theoretical.

SALT tracking works similarly. Property taxes connected through your mortgage servicer account update automatically. State income tax withholding shows up on your W-2 import.

Who it’s for: Homeowners with car loans and moderate complexity. Anyone who wants a single dashboard showing all their Schedule 1-A-relevant numbers.

Limitation: Monarch doesn’t have a dedicated tax summary export. You’re reading numbers off the screen rather than generating a document. For a current look at the platform’s overall state, check the Monarch Money winter 2026 review.

Cost: $14.99/month or $99/year.

Security: Read-only bank connections, multi-factor authentication, no credential storage.

Quicken Simplifi: Best for Overtime Workers

Quicken Simplifi handles income categorization more granularly than most budgeting apps.

For overtime tracking: Simplifi lets you tag income transactions with custom labels. If your employer runs overtime pay as a separate payroll deposit or line item, you can tag it as “overtime” and Simplifi totals it across the year. If overtime is buried in a single paycheck total (which it usually is), you’ll still need your pay stubs. Simplifi helps you reconcile what’s hitting your bank account against what the stubs show.

The watchlists feature is useful for car loan tracking. Set up a watchlist for your auto loan account, and Simplifi tracks monthly payments and can show interest vs. principal breakdowns if your lender reports them.

At $5.99/month (billed annually), it’s the most affordable paid option here.

Who it’s for: W-2 employees with overtime income who want income categorization without paying full Monarch or Copilot prices. Also works for anyone tracking multiple income sources.

Limitation: No direct loan servicer integration as strong as Monarch’s. Car loan interest tracking works if you manually enter it or your lender account connects cleanly. See the Quicken Simplifi 2026 review for the full breakdown.

Cost: $5.99/month (annual) or $7.99/month.

Security: 256-bit encryption, read-only bank connections via Plaid and Finicity.

YNAB: Best for Variable Income and Tip Budgeting

YNAB (You Need A Budget) doesn’t track deductions directly. What it does better than any other app is help tip workers and hourly employees budget around variable income, which indirectly supports deduction maximization.

Here’s the connection: tip workers often underreport income to themselves. The month-to-month variation makes it hard to know what you actually earned. YNAB’s zero-based budgeting requires assigning every dollar, which forces you to account for all income, including cash tips you might otherwise mentally ignore. Over a full year, that discipline produces an accurate tip income picture.

The reports section in YNAB shows total income by category by month. If you’ve labeled tip income consistently, year-end totals are right there.

This doesn’t replace Box 7 from your W-2 as the authoritative number. But for filers who think they earned more in tips than their W-2 shows, YNAB records can help you verify (or identify a discrepancy worth investigating with your employer).

Who it’s for: Tip workers with variable income who struggle to track what they earn. Also useful for anyone who wants to be deliberate about SALT spending (property tax timing, estimated state tax payments).

Limitation: At $14.99/month (or $99/year), it’s expensive relative to what it adds for pure deduction tracking. If your income is relatively stable and you just need to pull numbers, Simplifi or Monarch is more efficient.

Cost: $14.99/month or $99/year. Occasional 34-day free trial.

Security: Read-only bank connections, two-factor authentication.

The Free Option: A Spreadsheet That Actually Works

Not everything requires a subscription.

For the car loan interest deduction specifically, a simple spreadsheet handles it. Your loan servicer either sends a year-end interest statement or it doesn’t. If they do, you’re done. If they don’t, grab your last 12 monthly statements (most servicers have these in the online portal) and add up the interest column.

For the SALT deduction: your property tax bill shows the total paid. State income tax withheld is on your W-2. Two numbers, no app required.

For the senior deduction: check your birthdate, confirm MAGI is under $150,000 single / $300,000 joint, done.

The only deductions that genuinely benefit from an app are tips (if you earn them frequently and have variable totals) and overtime (if your W-2 doesn’t break it out clearly). If neither applies, a spreadsheet gets you to the same number in less time than signing up for a service.

IRS Free File: Worth Knowing Before You Pay Anything

This is only tangentially about apps, but it affects your cost calculation.

The IRS Free File income limit jumped to $89,000 AGI this year. Fewer than 3% of eligible filers use it, which means the vast majority of people who could file free are paying $30–$100 for software instead. If your AGI is under $89,000, check Free File eligibility before buying anything.

The IRS Free File income limit guide for 2026 walks through which providers are participating this year and what return complexity each covers.

How to Actually Use These Apps Before April 15

If you’re starting today, here’s the fastest path to having the numbers you need.

For tip income: Open Copilot or YNAB, connect your bank and payroll accounts, and look at 2025 deposit history. Tag income as “tips” vs. “base wages” if your employer runs them separately. Compare your total to Box 7 on your W-2. If the W-2 number is lower than what you actually deposited, that’s a conversation to have with your employer before filing.

For overtime: Pull your December 2025 pay stub (or your year-end payroll summary if your employer provides one). You need: total overtime hours, your regular rate, your OT rate. The deductible amount is (OT rate − base rate) × OT hours. Cap at $12,500 single / $25,000 joint.

For car loan interest: Log into your auto loan servicer account. Download the 2025 interest summary or annual statement. Total interest paid goes directly into your Schedule 1-A calculation, up to $10,000.

For SALT: Box 17 on your W-2 for state income tax withheld. Add your property tax bill total. Combined, subject to the $40,000 cap.

Once you have these numbers, the Schedule 1-A best tax software guide covers which platforms handle each deduction correctly when you go to file.

What No App Can Fix

A few honest notes before you download anything.

Apps track what you connect. If you earn cash tips and don’t deposit them, no software knows they exist. The OBBB tips deduction only covers tips reported through employer payroll (W-2). Cash tips you kept but didn’t report don’t qualify. The IRS has gotten sharper at cross-referencing employer payroll records with individual returns.

Overtime deductions require your employer to have paid overtime as defined under FLSA. Salaried-exempt employees who worked extra hours don’t qualify, regardless of what an app shows. If you’re not sure whether your role qualifies, check the OBBB tax deductions W-2 guide for the full occupational criteria.

And no app substitutes for reading your W-2 carefully. Schedule 1-A deductions are only as accurate as the underlying W-2 data. Start there before assuming any app total is correct.

FAQ

Which app is best for tracking tip income for taxes?

Copilot Money handles tip income tracking most effectively. It lets you tag paycheck deposits by income type and builds a year-to-date total you can compare to Box 7 on your W-2. YNAB is the better choice if you need to budget around variable tip income throughout the year, not just track it.

Can I use a budgeting app to track car loan interest for Schedule 1-A?

Yes. Monarch Money has the strongest auto loan integration. It connects directly to most loan servicers and shows interest paid by month. Alternatively, your loan servicer’s online portal should have a 2025 interest summary you can download without any additional app.

Does YNAB help with Schedule 1-A deductions?

Not directly. YNAB doesn’t generate tax reports. But for tip workers, YNAB’s income tracking disciplines produce an accurate year-end income picture that helps verify W-2 totals. It’s a budgeting tool being used for a secondary tax-prep purpose.

Is there a free app to maximize OBBB deductions?

The IRS-recommended path is still the most underused: IRS Free File handles Schedule 1-A deductions for filers under $89,000 AGI at no cost. For tracking (not filing), a spreadsheet with your pay stubs and loan statements covers most situations without a subscription.

What’s the difference between Schedule 1-A and the regular Schedule 1?

Schedule 1-A is the new deduction addendum created under OBBB specifically for tips, overtime, car loan interest, and the senior deduction. It’s above-the-line, meaning you take it in addition to the standard deduction, not instead of it. Regular Schedule 1 covers existing above-the-line deductions like student loan interest and educator expenses.
