How do I record a bill that's only partly for work?

Record the full bill with vendor, date, and amount, and add a short note describing the business portion and how you arrived at it. Cash Workspace keeps the record and the bill together for review; it does not calculate the split for you.

Are home-office costs deductible?

Whether an expense is deductible depends on your situation, so confirm it with a qualified accountant or tax professional. You can flag items 'potentially deductible — confirm with a professional' so they're easy to raise.

Does Cash Workspace read my utility bills automatically?

No. You enter each cost by hand and attach the bill yourself. Cash Workspace does not sync with your bank and does not read, scan, or extract data from your bills.

Keep home-office expense records you can actually review

When you work from home, your business costs hide inside personal bills: the same internet line, the same electric bill, the same phone plan. If you never separate them into their own records, year-end becomes a guessing game. Cash Workspace gives you one place to record each home-office cost as its own line with a vendor, date, amount, and the receipt or bill attached.

The problem

Why home-office costs get muddled

Home-office spending is rarely one clean charge. It is a slice of bills you also pay personally, plus one-off purchases that blur into household shopping.

Internet and electricity are paid as household bills, so the business share never gets recorded anywhere.
A desk, chair, or monitor gets bought with the same card as groceries and disappears from your records.
Phone costs are split between personal calls and client calls but logged as a single lump.
By tax time you're scrolling through statements trying to reconstruct what was for work.
Receipts for supplies pile up in a drawer with no link to the expense they paid for.

The workflow

Turn home-office costs into clean records

Record each cost as its own line, note how you arrived at any business portion, and attach the bill.

1
List your recurring bills
Write down the bills that carry a business share: internet, electricity, heating, phone. These repeat every month.
2
Record each as its own expense
For every bill, create a record with vendor, date, and amount, and note the portion you treat as business in the description.
3
Add one-off purchases
Log desk, chair, monitor, lamp, and supply buys as separate records under the right category as you make them.
4
Attach the bill or receipt
Attach the utility bill, internet invoice, or store receipt to its record so the number and the proof stay together.
5
Flag tax-adjacent items
Note 'potentially deductible — confirm with a professional' on items you'll ask your accountant about, without assuming they qualify.

Record structure

What to record for each home-office cost

A consistent set of fields makes every home-office line reviewable at a glance.

Expense category: Pick a product category such as utilities, internet, phone, equipment, or supplies so similar costs group together.
Vendor: Who you paid — your ISP, electric company, phone carrier, or the store.
Date: The bill or purchase date, so it lands in the right month and fiscal year.
Amount: The full charge, with the business portion you treat as work noted in the description.
Business-portion note: A short note of how you arrived at the share, e.g. 'home office is one of five rooms' or 'work line, 100%'.
Receipt or bill: The utility statement, internet invoice, or store receipt attached to the record.
Review flag: An optional 'potentially deductible — confirm with a professional' note for items to raise with your accountant.

Common mistakes

Mistakes to avoid

Recording a whole household bill as a business cost with no portion note.
Lumping internet, phone, and utilities into one 'home office' line so the detail is lost.
Assuming an item is deductible instead of flagging it to confirm with a professional.
Buying equipment on a shared card and never logging it as a separate record.
Keeping receipts loose instead of attaching them to the matching expense.
