Using Your Personal Phone for Business: How to Record It in Your Books

Why a business phone needs its own lines

A phone is one of the easiest places for the books to get muddy. One phone does the work calls, the client texts and the family group chats. The monthly bill covers all of it. The app store charges go on the same card. If every phone cost goes to one line called phone expenses, no one can tell what was business and what was personal at the end of the year.

The fix is to give each phone cost its own line. The bill goes to phone service. The apps go to software and subscriptions. A case, a charger and a screen protector go to phone accessories. When the month closes, the totals are already in the right places, and the personal share is kept out.

We set the lines up once in QuickBooks Online or Xero, and the same lines run every month. The bank feed and the card feed do some of the work, but we review every line, so a bad feed rule does not send a personal app charge to a business line all year.

Here is what happens when the lines are set up right.

When each cost has its own row, the books tell the story of what the phone really cost to run for the business.

What goes in the phone lines

The phone lines hold the real costs of using a phone for work. The monthly bill is the big one. Work apps come and go. A case, a charger or a screen protector shows up now and then. Repairs happen when the screen cracks or the battery dies.

Each one gets its own account in QuickBooks. The reason matters because a year of phone bills is a big number, and a year of app charges is a different big number. If they share one row, you can not see which one grew. We keep them apart, so the totals stay clear.

The receipts and the bills are the proof. Every phone bill, every app charge and every accessory receipt gets tied to the transaction in the books. When the month closes, the cost is in the right line and the proof is on file.

Here is what we keep on file for each phone.

• **The monthly bill: ** each one tied to the transaction in the books.
• - **The app charges: ** each work app in its own line, not piled in one row.
• - **The accessory receipts: ** each case, charger or screen protector tied to the transaction.
• - **The repair bills: ** each one recorded when it happens.
• - **A note on the use: ** whether the phone is all business or part personal.

Keep the records in one place. We tie them to the books as we go, so nothing is missing at year end.

Keeping the personal share out

A phone used for business is also a personal phone a lot of the time. The same device takes the client calls and the family calls. The same data plan streams the work emails and the music. The costs are real, but only the business share belongs in the business books.

The clean way is to keep the business costs in the books and the personal share out. When the phone is used for both, the full bill goes in its own line, and we add a note that the use is mixed. Your CPA decides how the split works. We keep the records clean so they have good numbers to start from.

Here is what to do when a phone is used for both.

• **Record the full phone bill in its own line.** The total is on file, and the split is a note for your CPA.
• - **Keep the work app charges in their own line.** Each one tied to the transaction.
• - **Do not put the personal share in the business books.** It does not belong there, even if the same phone is used for both.
• - **Add a note that the use is mixed.** Your CPA needs to know the phone was not all business.
• - **Tie every business receipt to the transaction.** The proof stays on file so nothing is missing at year end.

The split is your CPA's call. We keep the costs in the right lines and the personal use noted, so the books are clean either way.

Some owners buy a separate phone for the business. When the phone is all business, the full bill goes in the books and no split is needed. We still keep the bill tied to the transaction and the receipt on file. When the phone is mixed, the note goes on the line so your CPA can see it.

The records that hold it together

A phone in the books needs a few records to stay clean. The lines in QuickBooks are the big one. The bill is the proof. The app charges and the accessory receipts fill in the rest.

We keep the phone costs in their own lines, not in one general row called phone expenses. We tie the bills to the transactions. We keep the full bill on file. We note which phone each cost belongs to if you have more than one. And we add a note when the use is mixed, because your CPA needs it either way.

If you run more than one phone for the business, each one gets its own set of lines. The bill for phone one does not mix with the bill for phone two. The app charges for each one stay in their own rows. That way the cost per phone is clear, and a big repair bill on one phone does not hide in the total for the whole set.

Here is what we keep on file for each phone.

• **The monthly bill: ** each one tied to the transaction in the books.
• - **The app charges: ** each work app in its own line.
• - **The accessory receipts: ** each case, charger or screen protector tied to the transaction.
• - **The repair bills: ** each one recorded when it happens.
• - **A note on the use: ** whether the phone is all business or part personal.

Keep the records in one place. We tie them to the books as we go, so nothing is missing at year end.

What your CPA decides, not us

We keep books and run payroll. We do not prepare taxes. We do not give tax advice. We do not tell you what share of your phone bill to claim or whether to buy a separate phone. Those are calls for your CPA or tax preparer.

What we do is keep the records clean so your CPA has good numbers to start from. The lines are set up right. The bills are tied to the transactions. The personal use is noted. The receipts are on file. Your CPA can read the books and make the calls.

When the tax questions come up, we point you to your CPA. We answer their questions about the books, but we do not give the advice. You can read more about how we keep the books on our bookkeeping page, and about payroll on our payroll page.

A situation we clean up

The one line called phone expenses

A small business owner uses one phone for work and for personal calls. The monthly bill, every app charge and every case goes to one line called phone expenses. No note on what was business. No split between the lines. At year end, the CPA asks what share of the phone was business and what was personal. The owner can not tell from the books, and the bills are in no order.

Here is how we handle it. We set up separate lines for each phone cost. We pull the bills for the open months and tie each one to its transaction. We keep the app charges in their own line and the accessory receipts in their own spot. We add a note that the business share is your CPA's call. We close each open month one at a time, from the oldest forward. Then the routine runs every month, so the next year end starts with clean books and a note on the line.

Common questions

How do I record a personal phone used for business in my books? Give each phone cost its own line. The bill, the apps and the accessories each in their own account. Tie every receipt to the transaction. We set the lines up once and keep the costs in the right spot every month.

What do I do with the personal share of the phone bill? Record the full bill in its own line and add a note that the use is mixed. Do not put the personal share in the business books. Your CPA decides how the split works. We keep the records clean so they have good numbers to start from.

Do I need a separate phone for the business? You do not have to. A separate phone makes the books simpler because the full bill goes in and no split is needed. When the phone is mixed, we add a note so your CPA can see it. The choice is your CPA's call, not ours.

Do you tell me what share of my phone to claim? No. We do not prepare taxes or give tax advice. We keep the costs in the right lines and the personal use noted, and your CPA decides the share. You can reach us on our contact page if you want a team that keeps your phone costs clean.
