π¨ Self Assessment Reminder β Payment on Account Due 31 July π¨
A quick reminder for anyone who completes a Self Assessment tax return β the second Payment on Account is due by 31 July 2026.
Payments on account are usually made in two instalments, due on 31 January and 31 July each year.
This often catches people out because it arrives in the middle of summer, long after the January filing deadline has been forgotten!
β
You may need to make a payment if:
β’ You are self-employed, a landlord, or have other untaxed income.
β’ Your previous Self Assessment tax bill was over Β£1,000.
β’ Less than 80% of your tax was collected at source.
π‘ Remember, a Payment on Account is an advance payment towards your next tax bill, based on your previous year's liability. If your income has reduced since then, you may be able to apply to reduce the payment.
β οΈ Missing the deadline can result in interest being charged on the outstanding amount.
