How Work Reimbursements Are Taxed

The Two Types of Reimbursement Plans

1. Accountable Plan: Tax-free reimbursements (if requirements met) 2. Non-Accountable Plan: Taxable reimbursements (treated as income)

The difference: How the reimbursement is structured and documented.

Tax Treatment Summary

Accountable Plan:

• Reimbursement is not taxable income
• Not reported on W-2
• No tax impact

Non-Accountable Plan:

• Reimbursement is taxable income
• Reported on W-2
• You pay tax on it
• You cannot deduct expenses (employees can't deduct since 2018)

Key point: Structure matters. Same expense, different tax treatment depending on plan type.

Accountable Plans: Tax-Free Reimbursements

What Is an Accountable Plan?

Accountable plan is an employer reimbursement arrangement that meets IRS requirements.

If requirements are met: Reimbursements are tax-free.

Requirements for Accountable Plans

Three requirements (all must be met):

1. Business Connection

• Expense must have business connection
• Must be for business purpose
• Must be ordinary and necessary

2. Substantiation

• Employee must provide documentation
• Receipts, expense reports, etc.
• Must show: Amount, date, location, business purpose

3. Return of Excess

• Employee must return any excess reimbursement
• Cannot keep reimbursement that exceeds expenses
• Must return within reasonable time

If All Requirements Met

Reimbursement is:

• Not taxable income
• Not reported on W-2
• No tax impact

Employee benefits: Get reimbursed tax-free, no tax on reimbursement.

Example: Accountable Plan

Scenario:

• Employee travels for business
• Spends $1,000 on business expenses
• Submits expense report with receipts
• Employer reimburses $1,000

Tax treatment:

• Reimbursement: Not taxable
• Not on W-2
• No tax impact

Employee keeps: Full $1,000 (tax-free).

Non-Accountable Plans: Taxable Reimbursements

What Is a Non-Accountable Plan?

Non-accountable plan is any reimbursement arrangement that doesn't meet all three requirements of an accountable plan.

If requirements are not met: Reimbursements are taxable.

Tax Treatment

Reimbursement is:

• Taxable income
• Reported on W-2 (as wages)
• You pay tax on it

Important: Since 2018, employees cannot deduct business expenses. So if reimbursement is taxable, you pay tax on it and cannot deduct the expenses.

Result: You're worse off than with accountable plan.

Example: Non-Accountable Plan

Scenario:

• Employee travels for business
• Spends $1,000 on business expenses
• Employer gives $1,200 "allowance" (no documentation required)
• Employee keeps the $200 excess

Tax treatment:

• Reimbursement: Taxable income
• Reported on W-2: $1,200
• Tax on $1,200 (at your rate, e.g., 24% = $288)
• Employee keeps: $1,200 - $288 = $912 (less than expenses!)

Employee is worse off: Paid tax on reimbursement, cannot deduct expenses.

What Expenses Can Be Reimbursed?

Qualifying Business Expenses

Common reimbursable expenses:

• Business travel (airfare, hotel, meals)
• Business meals (50% deductible for employer)
• Car expenses (mileage or actual)
• Business phone calls
• Business supplies
• Professional development (conferences, training)
• Home office expenses (if qualified)
• Business equipment

Must be: Ordinary, necessary, and for business.

Non-Qualifying Expenses

Not reimbursable (or taxable if reimbursed):

• Personal expenses
• Commuting (home to regular workplace)
• Entertainment (since 2018)
• Personal portion of mixed expenses

If employer reimburses these: Usually taxable.

Documentation Requirements

What Must Be Documented

For accountable plan, document:

1. Amount: Cost of expense
2. Date: When expense occurred
3. Location: Where expense occurred
4. Business purpose: Why expense was necessary
5. Business relationship: Who you met with (for meals)

Receipts

Keep receipts for:

• Lodging (always required)
• Meals over $75
• Transportation (airfare, etc.)
• Other expenses over $75

For expenses under $75: Receipts not required, but still document.

Expense Reports

Submit expense reports with:

• List of expenses
• Receipts attached
• Business purpose for each
• Dates and locations

This substantiates expenses for accountable plan.

Per Diem Alternative

If using per diem rates:

• Still need to document: Dates, location, business purpose
• Don't need receipts for meals (per diem covers it)
• Simpler documentation

Employer can use per diem instead of actual meal costs.

Common Reimbursement Scenarios

Scenario 1: Accountable Plan - Business Travel

Situation: Employee travels, submits expense report, gets reimbursed

Tax treatment:

• Reimbursement: Not taxable
• Not on W-2
• No tax impact

Employee benefits: Tax-free reimbursement.

Scenario 2: Non-Accountable Plan - Allowance

Situation: Employer gives monthly "allowance" for expenses, no documentation required

Tax treatment:

• Allowance: Taxable income
• On W-2
• You pay tax on it

Employee is worse off: Pays tax, cannot deduct expenses.

Scenario 3: Mixed - Some Accountable, Some Not

Situation: Employer reimburses some expenses (accountable), gives allowance for others (non-accountable)

Tax treatment:

• Accountable portion: Not taxable
• Non-accountable portion: Taxable
• Only taxable portion on W-2

Employee: Pays tax only on non-accountable portion.

Scenario 4: Reimbursement Exceeds Expenses

Situation: Employee spends $800, employer reimburses $1,000

If accountable plan:

• Must return $200 excess
• If returned: $800 is tax-free
• If not returned: $200 is taxable

If non-accountable plan:

• Entire $1,000 is taxable
• No requirement to return excess

Scenario 5: Employee Doesn't Submit Expenses

Situation: Employee has expenses but doesn't submit for reimbursement

Tax treatment:

• No reimbursement = No tax impact
• But: Employee cannot deduct expenses (employees can't deduct since 2018)
• Employee pays expenses out of pocket with after-tax dollars

Employee is worse off: Pays expenses with no tax benefit.

Reimbursement vs. Allowance

Reimbursement (Accountable Plan)

How it works:

• Employee incurs expenses
• Submits documentation
• Employer reimburses actual expenses
• Tax-free (if accountable plan)

Advantages: Tax-free, covers actual expenses Disadvantages: Must document, may take time to get reimbursed

Allowance (Non-Accountable Plan)

How it works:

• Employer gives fixed amount
• No documentation required
• Employee keeps any excess
• Taxable income

Advantages: Simple, immediate Disadvantages: Taxable, may not cover all expenses

Which Is Better?

For employee: Accountable plan (reimbursement) is better (tax-free).

For employer: Accountable plan is better (deductible, not subject to payroll taxes).

Both benefit from accountable plan structure.
