Quick answer
- Expenses reduce the amount available from turnover before personal take-home planning.
- Common contractor costs include accounting, insurance, software, equipment, training, professional membership and unpaid admin time.
- Do not assume every personal cost is a business expense; allowable treatment should be checked against Revenue guidance or accountant advice.
- The safest pricing approach is to include recurring costs before deciding your minimum rate.

Costs to list before quoting a rate
| Cost type | Examples | Pricing impact |
|---|---|---|
| Professional | Accounting, legal review, insurance | Raises minimum annual turnover |
| Tools | Software, laptop, subscriptions, hosting | Should be spread across billable work |
| Training | Courses, certifications, conferences | May reduce billable days and add direct costs |
| Admin | Bookkeeping, invoicing, proposal writing | Often unpaid unless priced indirectly |
| Protection | Pension, emergency buffer, income gap planning | Important for long-term sustainability |
Expense planning rule
Separate three lists: costs you definitely pay each year, costs that depend on the contract, and personal costs that should not be treated as business costs without checking. Then use your day rate to cover the first two groups before counting the rest as personal income.
Pricing cost versus tax deduction
A cost can be commercially real without being fully deductible for tax. Your day rate may need to recover personal protection, downtime or a mixed-use item even when the tax deduction is restricted. Keep the pricing calculation and the tax computation as two separate schedules.
| Item | Pricing treatment | Tax question |
|---|---|---|
| Accountancy and business insurance | Include recurring annual cost | Was it incurred for the trade? |
| Laptop or equipment | Recover cost over useful contracts | Expense now or capital allowance treatment? |
| Phone / broadband | Include business share | How is mixed private use apportioned? |
| Training | Include fee and lost billable time | Does the course maintain the existing trade or create a new one? |
| Pension and emergency buffer | Build into required revenue | Not an ordinary trading expense; review separate rules |
Mixed-use and capital costs
Revenue states that where an expense has both business and private use, only the business portion is claimed. Phone, motor and premises costs therefore need a defensible apportionment. Equipment and other capital items may not be deducted in the same way as routine running costs; capital allowances may apply instead.
A spreadsheet entry is not enough on its own. Keep the receipt or invoice, payment evidence, business purpose and the calculation used for any private-use restriction.
Six-year contractor records checklist
- Sales invoices, credit notes and contracts.
- Expense receipts and supplier invoices.
- Bank, card and payment-provider evidence.
- Mileage or travel purpose records where relevant.
- Asset purchase documents and capital-allowance schedules.
- VAT invoices and VAT return workings.
- Year-end accounts, tax computations and filed returns.
- Notes supporting business/private apportionments.
Revenue says original business records used for Income Tax, Corporation Tax or CGT calculations must generally be retained for six years. Digital storage can help, but the contractor remains responsible even when an accountant keeps the records.
Frequently asked questions
Should I include accountant fees in my day rate?
Yes for pricing. Even if the tax treatment is checked separately, recurring professional costs should be covered by your rate.
Are all contractor costs tax deductible?
No. Allowable treatment depends on Revenue rules and your exact circumstances, so check before relying on a deduction.
Should unpaid admin time be priced?
Yes. Even when it is not invoiced directly, it reduces the number of days available for paid client work.
Can I claim the full cost of a phone or broadband bill?
Only the business portion should be claimed where there is mixed private use. Keep a reasonable and supportable apportionment.
Is a laptop always an immediate expense?
Not necessarily. Equipment can require capital-allowance treatment rather than a full immediate trading deduction, depending on the facts.
Can I claim ordinary commuting or meals?
Do not assume so. Travel, subsistence and ordinary personal living costs have detailed restrictions and should be checked against Revenue guidance.
How long should contractor expense records be kept?
Revenue generally requires the underlying business records and linking documents to be retained for six years.
