Tax Prep Notes on iPhone: The Year-Round System for Freelancers and Self-Employed

Tax preparation is an information retrieval problem. Every year, people overpay or miss legitimate deductions because they cannot reconstruct what happened eleven months ago. The receipts are somewhere. The business meal was definitely deductible. The home office calculation needs a number you wrote down once and now cannot find.

The fix is simple: a note-taking habit throughout the year, not a frantic search in January.

Who This System Is For

This system is designed for:

• Freelancers and contractors tracking business income and expenses across multiple clients
• Self-employed professionals managing a combination of employment income and sole trader activity
• Landlords logging rental income, repairs, and allowable property expenses
• Side-business owners maintaining records separate from their primary employment
• Employed individuals with significant non-standard deductions (home office, professional subscriptions, charitable giving)

If your tax situation is entirely handled by a single employer and you have no additional income or deductions, this system adds less value. For everyone else: the investment pays for itself the first year.

The Core Principle: Capture at the Point of Expenditure

The right time to log a business expense is when you incur it — not at month-end, not before the tax return deadline. At the moment of purchase you know:

• What you bought
• Why it was for business
• Who you were with if it was a meal or entertainment
• The exact amount

One week later you may still know these things. Three months later you will know some of them. Eleven months later you will struggle to reconstruct the context that makes the expense deductible.

Nemos opens in one tap. Log the expense before you put your card away.

Folder Structure for Tax Notes

[Tax Year] — Expenses One note per expense category or one rolling note per month — whichever you will actually maintain. Running log of business expenditure with date, amount, vendor, and business purpose.

[Tax Year] — Income All income sources: client payments received, invoice dates, amounts, VAT if applicable. Essential for freelancers and multiple-income individuals.

[Tax Year] — Receipts Log Not the receipts themselves (use a scanner app for those) but a log confirming which receipts exist: date, vendor, amount, file reference. Useful when your accountant asks "do you have the receipt for X?"

[Tax Year] — Mileage Date, destination, purpose, miles. Captures the business mileage log required for vehicle expense claims.

[Tax Year] — Meetings and Meals Business meals and entertainment: date, attendees, venue, amount, business purpose. The purpose documentation is what makes these deductible.

[Tax Year] — Home Office If you claim home office: note the days worked from home, any home-related costs (broadband, office supplies), the room used. Calculation happens at year-end but the data is captured throughout.

The Expense Log Entry Format

Keep entries consistent so they are scannable:

``` 2026-03-14 | Adobe Creative Cloud | £55.99/mo | Business software subscription — design work for client projects 2026-03-15 | Client lunch — Sarah (Apex Ltd) | £87.00 | Business development, discussed Q3 contract renewal 2026-03-18 | Train to London | £42.50 | Client meeting, Apex Ltd offices, Canary Wharf 2026-03-20 | Home broadband | £35.00/mo | 60% business use allocation — remote working ```

Date, vendor/description, amount, business purpose. Thirty seconds per entry.

---

The Mileage Log

HMRC and most tax authorities require a contemporaneous record of business mileage — a log written at the time of travel, not reconstructed afterwards. Nemos handles this:

``` 2026-03-14 | Home → Client (Apex Ltd, Manchester) | 47 miles | Client quarterly review meeting 2026-03-21 | Home → Accountant | 8 miles | Tax planning meeting ```

Simple. Defensible.

---

The Income Tracker

For freelancers with multiple clients:

``` CLIENT INVOICES — 2026 --- INV-024 | Apex Ltd | £4,200 | Issued 2026-03-01 | Paid 2026-03-18 INV-025 | Blue River Co | £2,800 | Issued 2026-03-15 | PENDING INV-026 | Apex Ltd | £1,500 | Issued 2026-03-28 | PENDING ```

Running total at the bottom. This is the document you send to your accountant in January and the record that reconciles against your bank statement.

Deductible Category Reference

Keep a reference note with the expense categories relevant to your situation. Not a legal guide — a personal checklist of your typical deductible expenses as agreed with your accountant:

• Professional subscriptions (bar membership, professional body, trade journals)
• Software subscriptions used for business
• Business travel (train, flights, taxis — not commuting)
• Business mileage (personal vehicle)
• Client meals (business purpose, attendees documented)
• Professional development (courses, books, conferences)
• Home office proportion (broadband, utilities, office supplies)
• Equipment (laptop, phone, peripherals with business use)
• Accountant and professional fees
• Marketing and advertising

Your categories will vary. The list is a prompt, not a prescription.

iPhone-Specific Tax Capture Workflow

At a business meal Before the card hits the table, open Nemos. Log: date, venue, names of attendees, business purpose. The receipt goes in your wallet or is emailed to you; the context note is in Nemos before you leave the restaurant.

On a business trip One running trip note: travel costs, accommodation, per diems, incidental expenses. Captured as they happen, summarised at the end of the trip.

After a client call If the call generates a chargeable event or a commitment, note it immediately. Time entries, agreed deliverables, and billing decisions decay fast in memory.

Share Sheet from banking apps Some banking apps allow you to share transaction details. Screenshot and add to your Nemos expense log. A two-step capture takes less than 30 seconds.

Connecting Notes to Your Accountant

When tax return time arrives, your Nemos notes are the source material your accountant needs. Options:

1. Export notes as text and paste into a shared document
2. Summarise each category into a table and email it
3. Walk through your notes during a screen-share call

The key is that the data exists, is organised, and does not need to be reconstructed from bank statements and memory. Your accountant will give you a better return if they do not have to guess.

GDPR and Privacy Note

Tax notes often contain client names, billing amounts, and business relationship details — information that falls under data protection regulations in some jurisdictions. Nemos stores data on-device by default, not on external servers. This is appropriate for sensitive financial records that you are not required to share beyond your accountant and tax authority.

FAQ

Do I need a dedicated accounting app instead? If you need formal bookkeeping, VAT returns, or invoicing features, an app like QuickBooks, FreeAgent, or Xero is the right tool. Nemos is the pre-accounting capture layer — where you log the information before it goes into a formal system.

Can I log expenses in any currency? Yes — note the currency alongside the amount. For multi-currency freelancers, add the exchange rate at the date of the transaction.

What if I miss a few weeks of logging? Bank statement review can reconstruct most entries. Log what you can from memory with the caveat that business purpose may be approximate. Going forward, the habit prevents the gap from recurring.

Should I photograph receipts or keep paper ones? Use a dedicated receipt scanning app (HMRC's own app, Dext, or AutoEntry) for archiving receipts. Nemos logs the supporting context — the business purpose, attendees, reason for travel. The two systems complement each other.

How long should I keep these notes? HMRC requires records for five years after the tax year in question. Other jurisdictions have similar requirements. Archive your Nemos year-end notes rather than deleting them.
