Payments on account planner for landlords
Enter your tax bills and see exactly what you'll pay each January and July, so the 2027 rate rise doesn't catch you out.
Key facts
- If your Self Assessment bill is over £1,000, HMRC usually asks for two payments on account, each 50% of last year's bill.
- They're due on 31 January and 31 July.
- The 2027/28 rate rise shows up as a bigger balancing payment on 31 January 2029.
- No payments on account if 80% or more of your tax is collected through PAYE.
How payments on account work
Each payment on account is half of the previous year's bill. On 31 January you also pay any balance for the year just ended. Because payments on account are based on the previous year, a rise in tax isn't collected until the following January as a balancing payment, plus higher payments on account from then on.
Why January 2029 matters
Your 2027/28 bill, the first at 24%/44%/49%, is due by 31 January 2029. Payments on account for 2027/28 are based on 2026/27, at the old rates, so the increase lands in one go. Estimate it with the landlord tax calculator and set money aside monthly.
Can I reduce them?
If you expect lower profit, you can apply to reduce payments on account. If you reduce them too far, HMRC charges interest on the shortfall. You can also ask HMRC to collect up to £3,000 through your PAYE tax code if you file online by 30 December.
