Irish side income: Form 12 or Form 11 for PAYE workers?

You have a PAYE job in Ireland and a small paid activity outside it. Perhaps you prepare orders for an online shop, give lessons or do occasional design work. The practical question is which return to use, and which figures decide that. Revenue’s detailed guidance distinguishes taxable income from gross income. This article follows those distinctions, using official pages checked on 9 October 2026. If you are considering the work itself, the earn from home page explains how packing orders fits together.

Which two amounts should a PAYE worker check? #

Revenue’s self-assessment registration page sets two separate tests: taxable non-PAYE income exceeding €5,000, or gross non-PAYE income exceeding €30,000. Its PAYE return guidance also says Form 11 is required if you are taxed under self-assessment, for example where tax on your non-PAYE income is not collected through reduced PAYE credits and rate bands. Having a salary therefore does not, by itself, establish that Form 12 is the correct return.

For the smaller non-PAYE amounts, Revenue describes an online Form 12 through myAccount, with adjustments to collect tax through PAYE. If this is your first year, check your registration and collection arrangement before relying on that route. Tell Revenue what the activity is and what you expect to receive. This gives it enough information to answer the return question, rather than asking whether a vague “side hustle” needs declaring.

How do the gross and taxable tests differ in examples? #

The third example explains why checking only profit can miss a filing requirement. It could describe a separate activity with substantial receipts and costs. Do not copy those costs into a parcel-packing calculation: a shop’s stock is not a purchase by its sender. The last example illustrates the exact boundary. Revenue uses “exceeds” and “more than” in its detailed pages, so reaching a limit is different from exceeding it. Other reasons for Form 11 can still apply.

What counts as your receipts when you pack orders? #

AirPost’s published model has the shop send its products and packaging to you. You prepare its customer orders and earn the agreed fee. The shop pays for the label. Build your records around your own service fees, deductions and any separately agreed reimbursement. Neither the retail value of the shop’s products nor a label bought by the shop is automatically income from your packing service.

Keep the gross fee, any deduction and the amount paid out in separate columns. A bank deposit alone may not explain the whole transaction. If a payment combines fees with a repayment for materials, keep the conversation and receipt that explain the repayment. Ask Revenue or your adviser how to treat that item in your circumstances. A clear breakdown lets you check the treatment without guessing from a single balance total.

Can you deduct every cost connected with your home? #

Revenue’s business-expenses guidance allows expenses directly related to running the business and requires mixed personal and business spending to be separated. It also distinguishes capital expenditure from ordinary expenses. A household bill does not become entirely deductible because you prepare some parcels at home. Equally, money the shop spent on its own packaging is not a cost you paid. Work from evidence of your expenditure and the relevant business use.

For each receipt, write a short explanation beside it: what you bought, who paid, which activity used it and whether there was personal use. Put uncertain items in a separate list before calculating taxable income. For example, a shared telephone bill needs a different explanation from supplies bought exclusively for an agreed dispatch. Keeping that distinction from the start makes an annual total more useful than a folder of unexplained receipts.

How do you submit smaller extra income in myAccount? #

1. 1

   Confirm that this is your return route

   Check the Form 12 eligibility rules, your tax registration and whether tax on the extra income is being collected through PAYE. Use Revenue’s secure MyEnquiries service if the arrangement is unclear.

2. 2

   Prepare the relevant year’s figures

   Separate PAYE details from non-PAYE receipts, relevant costs and taxable amounts. Reconcile your service records with statements so you can explain any difference.

3. 3

   Open the previous-year review

   Revenue’s extra-income guide directs you to “Review your tax for the previous 4 years”, select the year and request a Statement of Liability, then complete the Income Tax Return.

4. 4

   Enter and submit the extra income

   Use the “Non-PAYE income” section and provide the relevant details. Complete the remaining questions, sign and submit, and save the acknowledgement and resulting documents.

These are Revenue’s previous-year filing steps, not instructions to put estimated current-year amounts into a closed year. Keep the period visible on your working sheet and on the return. If the information in your account differs from your records, investigate the difference before signing. That is particularly useful when a payment statement contains a deduction or an adjustment that your bank statement does not describe.

What changes if Form 11 applies? #

Revenue describes Form 11 as a return completed through ROS with a self-assessment panel. That panel includes income, profits, costs and the amounts of Income Tax, USC and PRSI due. Moving to that system is more than choosing a different name for the same form. Registration, the return and the payment calculation each need attention. Use the official self-assessment guide for your year, including its pay-and-file and preliminary-tax sections.

Before contacting Revenue, prepare a short description: your PAYE employment, when the additional activity began, expected gross receipts, expected taxable income and whether you already have an Income Tax registration. Add any other non-PAYE sources. This is a better question than “I earned a little online; do I need ROS?” It also helps an adviser identify whether the thresholds or another feature of your tax status determines the answer.

Which records should you keep throughout the year? #

Revenue’s business record page requires records continuously and says the original documents must be kept for six years. Keep invoices, payment statements, receipts and the calculations linking them to your return. For packing work, keep a separate operational list of stock and completed orders. It can explain a fee, but the stock list is not a substitute for an income record. The Irish parcel-packing guide explains the underlying work.

Review your running totals when new statements arrive. Compare all relevant non-PAYE activities, including work outside AirPost, rather than checking each source in isolation. A simple sheet with dated transactions and source references is enough to make the review repeatable. Store submission confirmations alongside the totals used for filing, so you can later see which figures were reported and which were still estimates.
