PCS Moving Expenses for Service Members: Form 3903 Step by Step

By SSgt Christian Horton

Page updated: October 21, 2026 · Official guidance last changed: July 1, 2026

Most people lost the moving expense deduction in 2018, but members of the Armed Forces on active duty kept it when the move is a permanent change of station. This guide explains the IRS test, the costs that count, how government reimbursements change the answer, and walks one invented member through Form 3903 line by line for a 2025 tax return filed in 2026.

Who can still deduct a move

The Form 3903 instructions say that for tax years beginning after 2017 you can no longer deduct moving expenses unless you are a member of the Armed Forces on active duty and, because of a military order, you move because of a permanent change of station. Publication 3 adds that the move has to be a result of the order, so a move you choose to make on your own is not covered. The IRS topic page on military moves also says that employees and new appointees of the intelligence community who move in 2026 or later may be treated as members of the Armed Forces for this purpose, which does not change anything for service members.

Publication 3 defines a permanent change of station as one of three kinds of move: from your home to your first post of active duty, from one permanent post of duty to another, or from your last post of duty to your home or to a nearer point in the United States. The last kind has a clock: it must happen within 1 year of ending active duty, or within the period the Joint Travel Regulations allow.

Where Guard and Reserve members stand

The IRS wording is about members on active duty moving under a military order. It does not use the word reservist in this rule, and it does not describe what happens when a Guard or Reserve member is called to active duty and moves under orders. The sources reviewed for this guide settle only the general test, so a reservist who moves under active-duty orders should keep those orders and ask a tax professional how the test applies. A move you make between drill weekends, such as taking a civilian job in a new city, would not appear to meet any of the three definitions above. Drill travel is a different deduction, covered in who qualifies for the travel deduction.

Which costs are deductible

Under the instructions, you can deduct reasonable expenses that were not reimbursed and not provided in kind, for two things: moving household goods and personal effects, and travel. The table sorts the common items using the wording in Publication 3 and the Form 3903 instructions.

Travel can include airfare, and the day you arrive counts. Household members do not have to travel together, but each person gets one trip. You cannot deduct general repairs, maintenance, insurance or depreciation on your car, goods you bought on the way, return trips to your old residence, unnecessary side trips or lavish lodging. Expenses are deducted in the year you paid or incurred them, and the instructions tell filers who make estimated tax payments to account for taxable reimbursements and deductible moving costs. Two details trip people up. First, the 30-day limit applies to storage after the goods are moved from the old home, not to every storage bill. Second, the household that counts is anyone who has both the old and the new home as a main home, which excludes a tenant or employee unless you can claim that person as a dependent.

The mileage rate to use

If you drive your own car, you can use the actual cost of gas and oil with a record of each expense, or a standard mileage rate. The Form 3903 instructions for 2025 give 21 cents a mile for moves in 2025. For 2026 the IRS set two moving rates for certain active-duty members of the Armed Forces: 20.5 cents a mile for January 1 through June 30, and 23.5 cents a mile from July 1 through December 31. A move in 2025 uses 21 cents on the return you file in 2026; a 2026 move uses the rate for the period it took place, and you should confirm both against the 2026 Form 3903 instructions when they are published.

Reimbursements and allowances

Most of the work in a PCS year is deciding what the government already paid for. Publication 3 says not to include in income the value of moving and storage services the government provided because of a permanent change of station. It also says dislocation allowance, temporary lodging expense, temporary lodging allowance and move-in housing allowance are not included in income. The catch is that a cost one of these allowances already covered cannot also be deducted: Publication 3 says not to deduct any expenses that were reimbursed by an allowance you did not include in income. In plain terms, the deduction is your own costs minus what the government paid toward them.

Line 4 asks for the total the government paid you for the line 1 and line 2 expenses that is not included in box 1 of your Form W-2, and the form says that figure should appear in box 12 of the W-2 with code P. The instructions say not to enter on line 4 the value of moving or storage services the government provided, or any part of a dislocation allowance, temporary lodging allowance, temporary lodging expense or move-in housing allowance. Costs those allowances covered are left off lines 1 and 2 instead. Then the form compares your expenses with that amount. If your expenses are larger, the difference is your deduction. If the government paid more than your expenses, you do not deduct anything, and the form tells you to include the excess on Form 1040 line 1h. Publication 3 carves out dislocation allowance, temporary lodging expense, temporary lodging allowance and move-in housing allowance: those are not income even when they exceed your costs. Publication 3 notes that when total reimbursements exceed your actual costs, the government generally includes the excess in your W-2 wages already.

Worked example: one move, two outcomes

The members below are invented. Both made a PCS move in 2025 under orders, drove their own cars and kept their receipts. The numbers show how Form 3903 works; they are not typical costs.

Member A's meals on the road ($190.00) never enter the form because meals are not deductible. A $1,507.00 deduction lowers taxable income by that amount, so the tax saved is $1,507.00 times the member's marginal rate; at an invented 12 percent rate that is about $181.00. In this example the $1,500.00 is assumed not to be in W-2 box 1 and to contain no dislocation, lodging or housing allowance, and Member B's payment was larger than the costs, so there is nothing to deduct and the form directs the $490.00 excess to line 1h. Notice that the two members spent different amounts and ended up on opposite sides of the same line, which is why the line 4 figure matters as much as the receipts.

Where the result goes

The Form 3903 form says to enter line 5 on Schedule 1 (Form 1040), line 14, for the 2025 tax year. Publication 3 says the same and adds that if you qualify for more than one move you use a separate Form 3903 for each. Because the deduction is an adjustment to income, it reduces adjusted gross income whether or not you itemize. The form also has a box at the top where you certify that you meet the active-duty and military-order requirements, so check it only if both are true.

Spouses, dependents and foreign moves

The checkbox on the form covers moves by you, your spouse or your dependents under the order, so family moves count when the order covers them. When the military moves you and your family to or from different locations, the instructions treat the moves as a single move. If you are the spouse or dependent of a member who deserts, is imprisoned or dies, a permanent change of station for you includes a move to the member's place of enlistment or induction, to your or the member's home of record, or to a nearer point in the United States.

A foreign move is a move from the United States to a foreign country or between foreign countries, and the instructions say a U.S. military base abroad is not United States territory for this purpose. For a foreign move the deductible costs expand to include moving household goods to and from storage and storing them while the new job location stays your main one. If you file Form 2555 to exclude foreign income, the instructions say to report the full amount on Form 3903 and see Publication 54 for the part tied to the excluded income. The same instructions have a separate path for members who moved abroad in an earlier year and claim only storage fees, which go directly on Schedule 1, line 14, with the box checked next to that line. The instructions apply that path only when the government-paid storage amount is included in box 1 of your W-2, and the foreign-move storage rule requires that the new job location is outside the United States.

What the sources do not settle

These IRS pages do not give an amount you can deduct without receipts, and the Form 3903 instructions say to complete the lines using your actual expenses. They also do not set a cap, but they do require that expenses be reasonable and exclude lavish lodging and unnecessary side trips. Questions about travel allowances, weight limits and entitlements belong to your finance office and the Joint Travel Regulations, not to the IRS pages cited here. If your Form W-2 box 12 code P figure does not match your pay records, ask your finance office before you file.

A short checklist before you file

• Confirm the move was due to a military order and counts as a permanent change of station.
• Collect receipts for packing, hauling, in-transit storage, lodging, tolls and parking, and leave out meals.
• Use 21 cents a mile for a 2025 move, or the 2026 rate for the period of your move (20.5 cents through June 30, 23.5 cents from July 1), if you do not track actual car costs.
• Find the W-2 box 12 code P amount and compare it with your line 1 and line 2 totals.
• Complete one Form 3903 per move and carry the result to Schedule 1, line 14.
• Keep the orders with your tax records.

Common questions

Can I deduct meals on the way?

No. The Form 3903 instructions say you cannot deduct any expenses for meals.

Is the dislocation allowance taxable?

Publication 3 says dislocation allowance is not included in income. It does not create a deduction, and any moving cost you paid with it cannot be deducted a second time. The costs it covered are left off lines 1 and 2 of Form 3903, and the allowance itself is not entered on line 4.

Do I need Form 3903 if the government paid for everything?

If the government paid for the costs and the amount is excluded from your income, there is nothing to deduct. Form 3903 is how you compare your own costs with what was paid, and the IRS pages reviewed do not say you must file it when you have no deduction.
