Relocation spending rarely lines up with the calendar year. A move approved in September may produce invoices in December and January, and each of those dollars has to land in the right tax year. This guide turns the year-end rush into a calendar, so HR, payroll and finance know what has to happen and when.
Why Year-End Is Different for Relocation
Relocation benefits are generally treated as taxable income for most employees, so every payment that the company makes or reimburses has to be reported correctly. Timing is what makes year-end hard. Costs are often paid weeks after the service happens, and payroll cutoffs arrive earlier than most teams expect in December. For the broader picture of how benefits are taxed, see relocation packages and taxes and what the latest tax law changes mean for relocation benefits. This post focuses on the dates.
November: Set Cutoffs and Chase Open Items
Start by deciding the last date for employees and vendors to submit relocation expenses for this tax year, and communicate it in writing. List every active relocation and its open items, such as household goods invoices, temporary living stays that cross year-end and home sale expenses that have not closed. Items you cannot resolve before the cutoff need a clear answer on which tax year they will fall into.
Check whether any employees have moved or are about to move between states this year, since that affects withholding and filing. Our guide to filing taxes in multiple states after relocating explains why.
Early to Mid December: Payroll Processing Cutoffs
Taxable relocation benefits and any gross-up payments must run through payroll, and the last payroll of the year has a hard cutoff. Confirm that date with your payroll team or provider now, then work backward to the date relocation data must reach them. Holiday schedules shorten the window, so treat the payroll cutoff as the real deadline, not the last day of the month.
Gross-up payments need particular care because they depend on a calculated tax amount. If a gross-up on a late expense misses the cutoff, the employee may be taxed on the benefit before they receive the offsetting payment. Our explainers on tax gross-up for miscellaneous allowances and tax gross-up show how those payments work.
Late December: Reconcile the Year
Once payroll closes, reconcile what was paid against what the relocation vendor reports. Match imputed income, equity, salaries and taxes against the checklist, and resolve differences while the people who know the answers are still reachable. We outline a five-step process in year-end relocation expense reconciliation, and the idea behind it is simple: the earlier you find a gap, the cheaper it is to fix.
January: Reporting Deadlines
Employers generally must furnish Forms W-2 to employees and file them with the Social Security Administration by January 31, or the next business day when that date falls on a weekend. Fourth-quarter payroll tax filings are also due around the end of January. Relocation payments that were taxable need to appear correctly in wages, so errors found now can require corrected forms.
State reporting may add its own dates, and some states have separate rules for withholding on relocation income. Ask your tax advisors for the calendar that applies to the states where your employees live and work.
April and Beyond: What Employees Need to Hear
Employees file their own returns by the spring deadline, and those who moved states during the year may need to file in two states. Many will be surprised that relocation benefits appear in their taxable wages. Share a short explainer in January, tell them who to contact, and consider tax filing assistance for the most complex moves.
Clear, early communication also protects the employee relationship. People who understand the tax treatment up front are far less likely to feel penalized later, which is why many companies review the policy alongside employee relocation policy essentials.
A One-Page Year-End Checklist
- Set and announce the final date for expense submissions.
- Confirm the last payroll date and the data deadline for relocation items.
- List open moves and decide which tax year late costs belong to.
- Run gross-up calculations early and review them.
- Reconcile vendor reports against payroll before the books close.
- Check W-2 and quarterly filing dates with finance and tax advisors.
- Plan a short message to employees about how relocation income appears on their forms.
